Buying a New Power Bank - What Specs would work?

SaberX on 12/01/2024 - 11:25

Hi brains trust. Just a bit confused on what to buy for a new power bank given all the latest charging speed techs. Last power banks I had were 6-8+ years so mAh was more a concern and we didn't have as much worry about QC 3.0 or 20w or 45 W ports etc.

I'm just abit amateur with the different charging speed and techs and therefore what power bank specs to purchase given the abundance of online listings.

I have an Oppo find X2 pro from the covid era ozbargain deal. It uses their 65w super vooc charging speed via my Oppo power brick. In the past I have used Samsung lines so had QC 2.0 power bricks and the like.

Are all phones backward compatible ? So 20 W or 45 W ports will all be utilised by my Oppo? How about if it's QC 3.0 or PD ports? What will work with opoo and other phones that aren't QC 3.0 or will your phone just dial back what it draws to suit?? Basically do I just aim for the highest output wattage ports power bank to get the fastest speed as the phones will negotiate a workable wattage and I presume if it's a flagship model it will draw the max watts ?

Will a 65 W advertised power bank which usually markets towards laptop PD charging work with my super vooc Oppo? Would love a super vooc charging power bank as the fast charge is great in a pickle.

Likely to upgrade to a Samsung s ultra line if prices drop. So hoping to be a bit future proof too.

Happy for any brand re recommendations. Just using Amazon at the moment and anker , veektomx, charmast and cygnet seem to be most of the china brands thrown. Just after small to medium for portability. But still decent capacity e.g. able to charge a 4500mah phone twice at least. So presuming a 10k maH capacity as best middle ground?

Also what is it the true capacity called again (not the stated capacity ) as I recall there's a difference to actual capacity but not all specs list it.

Sorry a few amateur questions. Besides knowing phones can draw a few diff combinations of watts depending on what the charger typically lists on its specs I'm just not across how electronics work with say power banks pumping out different standards /wattages.

    What Specs would work?

    Most of them.

    • SaberX on 12/01/2024 - 11:29

      I get that - I meant more from an electrical pov what power wattage or specification type e.g. qc3.0 works with day my Oppo or other phones that aren't that specific power speed , would give the fastest charging speeds?

      Basically do I just choose the power bank with 45 W over 20w ports out would give me the best bang for buck speed wise for any phones used to charge ?? Or is there a reason so many are 20w qc3.0 as it works better?

  • Shadowsfury on 12/01/2024 - 11:38

    Don't think you'll find ones at a reasonable price that would charge so quickly - the reasonably priced ones (say up to $35 for 10000mah type sizing) would top out at 18-22.5w - which to me is fine don't need to fast charge all the time especially with a battery you'll be carrying around anyway

    I try to look for the ones that are newer release dates (there's still heaps from 2019 or so as first sold date on Amazon) and don't have a micro-USB port - even if its redundant just slowly want that port out of my life.

    I last bought the INUI one from Amazon - and missed the associated sale that was posted earlier this week by just a few days.

    Just avoid the Heymix ones and you should be OK with whatever (INUI, Anker, Veekxxxxxx etc)

    • SaberX on 19/01/2024 - 01:52

      Yeah a micro USB port just isn't handy these days. Have plenty of USB a to micro USB devices to charge e.g. Bluetooth headphones etc but definitely not required for current day use.

      What's wrong with heymix if I may ask? I'll try and stick to the other 3 you mentioned otherwise. Someone below said baseus too was an avoid? Which I thought was also a reputable brand given its everywhere like heymix on listings?

      • Shadowsfury on 22/01/2024 - 11:52

        Look at the comments of some of their deals here - there'll be links to people's experiences with heymix devices (usually their chargers - blowing things/burning etc)

    OPPO use their proprietary VOOC charging technology.

    your phone supports:
    1）10V SuperVOOC: up to 65W(6.5A)，compatible with 67W(6.1A)、50W(5A)、33W(3A)

    2）5V VOOC: up to 20W(4A)

    3）PD (18W，9V/2A)

    unless you somehow source a VOOC compatible power bank from China, your best bet is to find a PD compatible charger that support 9V output.

    personally I have not heard INUI so I can't say they are good or bad, but I have plenty trouble with beasus so avoid it

    • SaberX on 19/01/2024 - 01:54

      Sorry missed this response previously. Out of curiousity why would a 9V PD power bank be best for my Oppo find X2 pro? You mentioned the 1) and 2) that my phone charges with so I was just genuinely interested how the charging voltage and current worked that 9V PD was recommended. Or was that more for cross comparability for future phones as mentioned?

      Notwithstanding the conversation on the Oppo power bank 2 below that is (which we now know has vooc).

      • OMGJL on 19/01/2024 - 11:19

        this comment was made before I know you can actually get a VOOC power bank from Australia.

        Logic is PD power bank is easy to get, likely cross compatible with later devices, and fastest (consider I thought you can't get VOOC stuff at all)

      actually not a bad choice.

      reading this review in Chinese

      the C port supports QC/PD which is the most common charging protocol.
      The A ports supports QC and VOOC

      30w would be enough to charge ipad or even some laptops.

      The only ugly part is to enjoy full VOOC charging, need to use the A-C cable included (No, you can't use other non-VOOC cable to enable VOOC) and for other charging you 'll want to have a C-C cable (still charges VOOC devices in a slower rate)

      OP I think this is your best bet albet the VOOC cable uglyness

      • Prong on 13/01/2024 - 10:31

        Yeah that is a good deal. And $25 is about half the price of buying it elsewhere and solid value considering the spec.

        And great find with that review. It does 3A PPS up to 11V, so should do Samsung 25W fast charging. Plus 15V which is useful in many cases.

        Definitely the best bet for OP.

        • SaberX on 13/01/2024 - 13:55

          May I ask why 15 v is useful in terms of charging ?

          I'll have to read up on what Samsung uses. First I've come across PPS. I thought Samsung were on qc2.0 or 3.0 last I knew. Although I came from a Samsung s8+ before my Oppo so I'm somewhat dinosaur.

          I did note the latest ultra (23?) I think is only 45 W or was it 25w? One of the reasons I was worried abt shifting as I've grown spoilt by the Oppo 65w super vooc. Having to juice up in a toilet break or a quick office water jug refill is awesome. 5-10 mins and your back at 80% and ready to go.

          Still scarred by the hour to get from flat back up with the old s8+.

          • Prong on 22/01/2024 - 12:09

            @SaberX: Many laptops will charge from 15V, and it is useful for things like USB-C to car accessory socket cables, which often use 15V triggers.

            PPS is where the power bank (or wall charger) and phone (or other device) communicate, and the charge supplies the specific voltage and amperage the phone wants.

            The phone will ask for the exact voltage needed to charge the battery (and adjust that as it charges) or an option such as double the voltage, which the phone then steps down. This approach means most or all of the heat generated during power conversion happens in the power bank or charger, rather than the phone. Heat is a key limiting factor for charge rate, so less heat in the phone means a faster charge rate.

            Options such as 65W SuperVOOC are not possible within the USB PD spec, so need custom chargers and cables, which is why it uses USB-A.

      • SaberX on 13/01/2024 - 13:54

        Thanks. So the A port supports vooc but not super vooc? Or is it same thing albeit super vooc just means the charging speed is closer to the 65w max it' does natively ?

        I have one or two Oppo official super vooc cables already that work super vooc on my 65w power brick and the cigarette port car charger (50w) I can use. If that's what you mean by using the included a-c?

        What happens if one used a non vooc cable on the A port or even charged the Oppo on the C to C port? How do the mobiles negotiate charging watt and speed when charging through a different protocol? Would a QC 3.0 port still be fastest compared to a qc2.0 or other protocol when plugging in say this Oppo??

        And similar light a 45 W output USB port would be much faster than the 20w as does it just work on sheer numbers?

        Edit:

        Only thing is trying to find some dimensions on the eBay listing. Seems quite large from reviews so hoping it's reasonably travel friendly. Is there a way to work out what the real capacity the 10000mah goes to? Charging capacity or whatever it's called?

    • SaberX on 13/01/2024 - 13:51

      Thanks. I'm happy to go Oppo for my Oppo super vooc but just noting I'm also keen for a power bank that will be future proofing as I'm probably a yr or so from the next mobile changeover which may mean Oppo, or something else e.g. back to Samsung or another brand.

      How would an Oppo charge without an Oppo power bank or super vooc. Would it charge faster if I went for a power bank with 45 W ports more so than the 25 W? So just go for higher output for higher speed or it doesn't necessarily dial back like that?

      • OMGJL on 13/01/2024 - 22:33

        So the A port supports vooc but not super vooc?

        Correct, means 30w charging —- but keep in mind with your "65w", it will only charge at 65w full speed for a very short period and will become 30 or so watt when the phone is somewhere above 40% charge. TL;DR is it won't be much slower than 65w fast charge albet half the digit number.

        why 15 v is useful

        some PD equipped high power device (for example laptop) can charge at 15v, higher voltage == wider support.

        ultra (23?) I think is only 45 W …. I was worried … I've grown spoilt by the Oppo 65w super vooc.

        this power bank supports PPS up to 11v and up to 3 Amps, Samsung charges at 9.5v (ref), so at 3A it's about 28.5w, so on this power bank, Samsung/OPPO will charge at the same speed.

        on wall power, Samsung takes 38mins from 0-80%, Oppo takes roughly 40mins for 0-100%, it's slower but not painfully slow. All phones will charge faster when it's near empty and slower as it charges.

        5-10 mins and your back at 80% and ready to go.

        more like 15mins from 0%, unfortunately samsung will only reach 35% ish (ref above)

        What happens if one used a non vooc cable on the A port or even charged the Oppo on the C to C port?

        16.7 watt ish.(ref - same link as above)

        How do the mobiles negotiate charging watt and speed when charging through a different protocol?

        they negotiate on plugging in and choose the highest priority charging protocols. priority is set by phone manufacturer, not something you should worry about, apart from making sure using the right cable.

        Would a QC 3.0 port still be fastest compared to a qc2.0

        no. QC3.0 or PPS have much finer voltage increment steps vs QC2.0/PD, not faster, just finer.

        dimensions

        148.44mm * 71.13mm * 16mm @ 223.6g, very typical average 10000mah size and weight. about same weight as iphone 13/14/15 pro max

        a way to work out what the real capacity the 10000mah goes to?

        read it as you can continue to drain 10000 mA for an hour (in 3.7v). in normal charging at 5v, that's 5200mAh.

        a 45 W output USB port would be much faster than the 20w as does it just work on sheer numbers?

        ON SUPPORTED PROTOCOL yes.
        if no protocol supported at all those number doesn't matter, it'll be 10w max

        a charger(power bank) may support say 10 different protocols, few does 30w, few does 20w, few does 15w, your phone will pick the fastest supported one, whatever that was.

        your 30watt charger may only does 20w or even 10w depends on what's plugged into it.

        I'm also keen for a power bank that will be future proofing

        dude, this supports PD and PPS and QC, that's about every non-proprietary protocols out there, and VOOC too.

        an Oppo charge without an Oppo power bank or super vooc

        dials to the next best protocols. As I told you above in my comment,
        3）PD (18W，9V/2A)
        if no PD, (say you have a charger does QC and other protocols but NO PD/VOOC), 5v2A @ 10W

        • SaberX on 17/01/2024 - 03:42

          Hey there. Just a quick one (will respond to your other comments later) but what review or site did you see that lists what protocols and the like are supported ? I've tried searching the power bank 2 (pbv02 model?) And all the results are either Australian sites selling it or indian and they all mention the 30 W USB C and USB a ports. None mention anything about PD and PPS/QC? Just wondering where you read what the ports support?.

          I've been googling the name /model and have struggled to find much more than the typical item listing info that comes up

          Will respond to the rest of your comments tomorrow. Lot to take in. Did you have any useful guides on reading up on how the phones negotiate what they draw? Noted your comments and responses on what phones would draw on power wise but just wanted to learn abit more about the 101 of all the protocols and what the speed defaults too if you don't have it. Similarly understanding how diff voltage and amps combine for the overall watts

          For example you mentioned Samsung charging at 9.5v X 3a so total ,28.5 wattd. Do basically a 30 W port means it will output up until 28.5 W max theoretically?

          And would one normally have to enquire what combination of v and a the port can handle. For example I know some wall chargers may do up to theoretical max but they are pre set v and a combinations aren't they ? So if your phone doesn't meet that combo of v and a even if the watts is within what would normally charge it , it won't charge correct? Or is this where the whole default back to 10w occurs (which is what you describe any non protocol compliant phone would charge with).

          I'm also keen to understand as you mentioned the use of the right cable. Given the proliferation of cables from China. In vooc case it has to be official to work. But for other phones like Samsungs are cables easily determine from the specs their compatibility to achieving max charging speeds ? Given alot of the cheap China stuff one used to buy just gets called "USB C" and many mum's and dad's assume that means it just works.

          • OMGJL on 17/01/2024 - 08:05

            @SaberX: 1, I posted the review above in my first or so comment, links to a Chinese site.

            There's no good way to know what a phone take, apart from hook it up with those charging protocol detectors showing on the site.

            2, to fast charge, the charger and the phone have to
            FIRST, talk in same protocol (example, talk in PD?QC?VOOC)

            SECOND, negotiate the highest voltage
            (Can you take 5v?9v?12v?)

            THIRD, charge at the MAX current, either the most a charger can provide, or the most a phone can take.

            No protocol, default 5-10watt,
            Have protocol, charge at the lower spec of whichever side have the most bottleneck.

            3, As far as cable goes.
            QC doesn't require special cable
            PD require a cable to have EMARK chip in them
            VOOC require OPPO's own chip in the cable ( you can see a detector pin deep in the middle on the USB A side)

            it's always recommend to buy a cable with thicker gauge copper wires, though till this date there's no guarantee unless you cut the damn thing open.

            Hence you want to buy a reliable brand that meet the charging requirements, and hope for the best.

            • SaberX on 04/02/2024 - 20:27

              @OMGJL: Hi there! Just an update. I've gotten the Oppo power bank and have given it a whirl. Somehow the difference in vooc that it comes up with is noticeably slower than super vooc. I've tried it at lower levels I E. Charge from 30% and also at higher levels. The power bank whether I use my normal super vooc cable or the included short one seems to only pump out about 50-65%/hr charge rates when using accubattery to measure. The voltage is just under 4v (3.99xx) but the charge current is in yellow circa 5-7watts. Mostly 6w.

              Meanwhile I've tested out the charging brick and the 50w super vooc via the car cigarette lighter and both blow into the mid 100%s /hr rates. Circa 140-160% usually. The watts is green and much higher mostly 20-23 watts constantly but with the fast charging at lower levels up to 27-30w spikes.

              I'm just curious your thoughts given you mentioned it'd still be reasonably fast on the power bank. Am I doing something wrong ?

              Also I am planning to buy an international travel adapter and the lencent ones online typically for entry levels do 12w (5v 2.4a) USB a. Some models do 65w PD via USB C. And I found this model that does 60w through usb A:

              Given it is gan technology like super vooc protocol would I get any super vooc charging through a 60w USB a port? It says 20 v X 3a and the post you did up above only seems to have 3 compatible charging protocol for my phone. Does it mean if I don't have a super vooc power brick essentially I can only access PD 9v X 2A - 18w Max via option 3? Or will phones negotiate a higher charge given the USB a port supports up to 60w?

              Sorry if it's a silly question given my lack of electronics and charging knowledge. If you could help me out ?

              Happy to pay $44 for the higher 60w USB a option , as I presume this would work well with future phones if we use Samsung ultra lines , the Mrs iPhone, and anything else. But if the Oppo will just default to 10w (is that the standard with no protocol not the 12w?) Then the entry level travel adapter's are only $20 that come with basic USB ports.

              This is the Amazon travel adapter gan mentioned above:

              https://www.amazon.com.au/LENCENT-Universal-International-Ch…?

              Edit: to make us of the USB C 65 W and even the USB a 60w do I just get a cable that has an emark chip that therefore allows PD? Does that mean if PD is possible then it is compatible with PPS (Samsung flagships)?

              Then given the travel adapter's USB ports support QC 4.0 I don't need any special cable just a phone or device that utilises that QC protocol.

              Hopefully I've understood the protocols correct?

              • OMGJL on 04/02/2024 - 22:10

                @SaberX:

                charge current is in yellow circa 5-7watts

                Voltage unit is V, Current is A, power = voltage*current, unit is W (Voltage/Amperage/Wattage) IDK what you meant

                I'm just curious your thoughts given you mentioned it'd still be reasonably fast on the power bank. Am I doing something wrong ?

                I wonder if you have inserted the cable deep enough, try plug and insert it super firmly.

                I also wonder if this power bank is genuine, look at this photo https://imgur.com/a/4yutTJD
                on the right hand side of the photo there's 2 green circle, highlighting the VOOC detecting pin (of the port and the cable) if the charger doesn't have it, then it's fake for sure.

                gan technology like super vooc protocol

                No, GaN is a technology to make power converting more efficient, which will reduce charger's physical size. not a protocol.

                if you buy this charger, you won't have access to VOOC anyway. The charger has no VOOC no matter if you use the A or the C port.

                if you bought it already, best to use a usbC-usbC cable, it'll charge with PD protocol. Your later device (samsung/iphone) all have PD, so it'll charge at whatever the best speed it could do itself.

                Hopefully I've understood the protocols correct?

                yes you are right. to summarize:

                PD/PPS have 3 requirements: 1. phone support PD/PPS. 2.Charger support PD/PPS. 3. Cable have emark chip.

                QC 4.0 have 2 requirements: 1. phone support 2.Charger support you still don't want to use a dodgy cable but no firm requirements.

                • SaberX on 04/02/2024 - 23:48

                  @OMGJL: This is what I meant by current. I know it doesn't match up to the electrical definition but this is what I see in accubattery when it's monitoring charging speeds.

                  Interestingly enough after coming home and plugging in it hit green watts e.g. 12 W current. Still nothing like the 22-23 W it tends to pull from super vooc power brick.

                  https://imgur.com/a/VDJq5F9

                  However while it started charging faster then you can see per this next two screenshots that are uploaded in that Imgur link that it's fluctuating back down to a yellow /red current i.e. quite low.

                  Is this normal or is there a fault? Both the cable from the charger and my personal one are fine charging via the power brick so it's not those. Looking at the power bank and the cable provided I think. I can see the extra clip inside the USB a housing. Not to mention the phone does say fast charging in the corner with the VOOC bubble in the middle. It's just so much slower vooc.

                  Also the power bank print on back says OPpo vooc power bank 2 30w model PV02 cell capacity 5000mAh 7.4V 37kWh. Rated capacity 5200 mAh(5v ~5A).

                  Is this correct? The listing states this is a 10,000 mAh power bank. The back of the box packaging has printed on it:

                  " 30W flash charging in both directions.
                  High energy density 10,000mAH llithium ion polymer cell. Compatible with PD, QC and other mainstream fast charging protocols).

                  It then has a *Uses two 5,000 mAh cells in series equivalent to 10,000 mAh capacity.

                  The sticker further down the back that is stuck on and not printed lists the same model number and colour and lithium cell type. But also lists cell capacity as : 5,000mAah 7.4V 37kwh. With a rated capacity of 5,200 mAh.

                  Is it therefore a 5000 mAh or 10,000 mAh power bank?

                  Regarding the gan travel adapter. I haven't bought it yet. I was just tossing up between cheap $20 version from lencent with standard USB ports or going this 60w USB A and USB C 65w.

                  So basically as I have no vooc technology the fastest I could charge by non vooc USB is via USB C ports PD? And 18W would be my maximum despite having a 65W USB C pd port?

                  So in summary PD is only available via USB C port? Similar to how vooc charging is only on USB A you can only have PD via USB C?

                  And do you need to still see what combinations of PD (voltage and amps are provided) as I presume all phones have certain combos they'll use ? And just because the port is 65W max will it be limited by what PD combination of current and amps the charger can give that the phone also takes??

                  Or does PD just take the theoretical maximum the phone can take if the charger is rated higher?

                  Edit:

                  Does the emark chip have a visible physical difference like the vooc pin you sent the picture of? Or you can only go off what's advertised or trial and error ?

                    @SaberX: with your powerbank, it's 99.9% genuine (have pin, show charging logo).

                    As for why it's slow, I don't have much clue, maybe somehow the manufacturer broke the VOOC charge protocol software, but super VOOC still works… send them a support ticket? by spec it's all fine to me, I don't see why not but shit happens… worst case it's still a good PD power bank..

                    any 10000mah powerbank on the market is rated in 3.7v battery voltage, but when it provide charge at 5v it will have less mah, so 10000/5000 is both correct (in different voltage), this is one of those marketing BS you see..

                    with alternative charger, no VOOC then fastest is PD. no matter how fast that PD is you end up with up to 18w (what your phone take)

                    And do you need to still see what combinations of PD

                    yes, for your phone it need to have 9v. best if it's > 2A

                    Does the emark chip have a visible physical difference like the vooc pin you sent the picture of? Or you can only go off what's advertised or trial and error ?

                    no physical difference by look, it's only an internal chip. You'll need to go by marketing slides. If marketing slides says it have it, then that's fine. emark chip isn't expensive, no point faking those usually.

                      @OMGJL: I can see in the images on the side of the travel adapter the 9V but 3 A. Can't find any 9V 2A combo. Does this mean it will revert to the next nearest voltage and amps combination listed on the adapter (I think it was 15 W or lower combined) or does PD dial down the amp so that a 9v 3A PD port can be used as a 9V X 2A = 18w which is what PD my Oppo find X2 pro handles?

                      Yes very odd that the power bank seems genuine… And the speed isn't quite there. The only other way I suppose is to find a VOOC PHONE CHARGER and compare the difference perhaps.

                      Anyway I will have to use it for now as it is for our upcoming trip. Better than nothing.

                      Any 100w advertised fast charging USB C to USB C cable online I presume includes emark then? Otherwise you wouldn't be able to get up to such high speeds I'm presuming?

                      The hardest pin to see when checking the genuine is the device port. Much easier seeing a back pin I found in the USB cable.

                      @OMGJL: Out of curiousity. What is the purpose with a USB A 60 W? If PD is over USB C what charging devices or protocols could use up to 60W in USB a?

                      Mainly curious as they sell other travel adapter's with various iterations where the watts per USB a and USB C vary up and down. Some they do 12 or 15 W across all USB a ports, and others like this one both USB c are 65w and one USB a is 60w. The second USB a is 5 W which I understand would charge lower powered items. But yeah what else could possibly use the USB a 60w?

                        @SaberX: voltage is what matters, amperage—— larger than what you need is good. Every electronic devices ever.

                        I have a VOOC charger (actually DASH but same thing, oneplus rebrand of VOOC), you can even have it if you are in SYD.

                        Any 100w advertised fast charging USB C to USB C cable online I presume includes emark then?

                        Correct.

                    @SaberX: Your phone is not charging at the full rate the power bank can output. Your phone is in control here, and sets the charge rate.

                    Why isn't it charging at up to 30W? Hard to know and you might have to contact OPPO and ask.

                    OPPO says SuperVOOC is backwards compatible with slower versions of VOOC, but it's not 100% clear what that means. EG, your phone supports SuperVOOC, but does that mean it is backwards compatible with VOOC? Or is the backwards compatibility only on the charger side?

                    I would assume you phone is backwards compatible with VOOC, but considering the voltage differences with SuperVOOC, perhaps OPPO did not include the necessary hardware in the phone to do 30W VOOC.

                    If so, then your best bet is likely PPS mode, which is via the USB-C port.

                    The OPPO power bank does up to 11V at 3A in PPS mode. SuperVOOC uses 10V, up to 6.5A. So the power bank can supply 30W at the right voltage for the phone. However I can't find any information on if the Find X2 Pro supports PPS, so it might not ask the power bank for this, and thus charge slower.

                    It's easy to test. Plug your phone into the USB-C port on the power bank with a quality USB-C to USB-C cable. Then see what AccuBattery says. Post the number or screenshot here and we can take a look.

                    Re: the power bank - it is 37Wh, which is equivalent to 10,000mAh at 3.7V. (and the same as 5,000mAh at 7.4V) So yes, it is a 10,000 mAh power bank.

                    The rated capacity at 5V, 5A = 5,200 mAh. This the usable capacity if discharging at 5V, 5A. This is the real world capacity after efficiency and other losses. This is also a perfectly normal rating.

    What is your budget? Will you be likely to also need to charge a laptop?

    As others have said, Oppo VOOC is very uncommon for power banks, so the best bet there is a Oppo power bank.

    For Samsung, you generally just need PPS support. But many power banks don't list PPS spec, even when they support it.

    Most newer power banks do support PPS, but you generally need a 45W or higher model to get full Samsung charging speeds.

      I'm not too sure what it costs for a decent power bank tbh. I would have though a $50 budget 8 yrs ago was a heap but if I pushed to $80 is that reasonable?? For a decent quality brand that pushes out good specs and won't melt down in my pocket haha.

      While I have an oppo now it would be nice to use super vooc but I was happy to go with a power bank that charged it as fast as possible without super vooc and that enabled me to use future mobile purchases e.g. Samsung and others. So future proof.

      I wasn't sure therefore if you just went with the largest watt outputting ports and qc3.0/pd… I wasn't sure what the conventions meant in terms of how an Oppo would draw power from these sources… Hence the thread. I just figured a higher output port or latest port tech would charge it faster?

      So Samsung use PPS and qc3.0 is more for other phone models and pd is more a laptop term if trying to charge a laptop e.g. I have a HP 65w charging laptop (spectre)?

    the wall of text just for a battery bank…. no tldr.

      Sorry but not everyone lacks patience and wants everything on a platter.

  • pn09 on 23/01/2024 - 11:32

    Don't want to hijack the thread but rather than create a new one I wanted to get a recommendation for a PowerBank to recharge an HP Probook - these laptops use 65W charger bricks.

    I quite liked the idea of the Iniu BI-B63 with the 3 year warranty - https://www.amazon.com.au/INIU-25000mAh-Portable-Charging-3-…

    Any tips from the brains trust? Cheers
