this is the new release high density battery Mini version of the older 25000mAh 100W INIU.
early slight discount is a common tactic to get people to try the product and get reviews.

cheaper than the Xiaomi 25000mAh 100W PD powerbank which was often posted for $139.

this INIU is much more compact and can also do 100W PD out of a single port. it achieves it with high density battery + stacked circuit inside.
if you have doubts about 100W output, many INIU powerbanks have been tested to achieve the output spec, the tests did mention it gets toasty when doing it though. marketing says 100W in/out but imo it might be 65W in, because that's the case with the smaller 20k Mini model (65W out but 45W in) but I could be wrong.

Xiaomi 25k: ‎18.8 x 8.13 x 2.79 cm; 580 Grams
INIU 25k: ‎11 x 7 x 3.6 cm; 440 Grams (9mm thicker but only 58% of the length of Xiaomi, 140g lighter).

Also available INIU 20000mAh (65W output max) new release Mini version is $76.49 delivered.
https://www.amazon.com.au/INIU-20000mAh-Compact-Portable-Cha…

in my opinion the 20k is slightly more impressive capacity to weight than the 25k but doesn't do 100W out. the 20k does 65W max out, and 45W in.
INIU 20k: 11 x 7.1 x 2.9 cm; 324.1 Grams.

this 20k one in particular was listed a month ago on amazon which then got removed. it's now back but looks like they combined the listings of the old and new Mini together as "options" so be careful not to click the wrong one.

    also worth mentioning, even though Xiaomi is bigger heavier and more expensive it has been said it uses high quality Samsung 21700 batteries inside.

    the ultra cheap (2 year old stock) Limeta 10000mAh powerbank deal I posted is also said to use Samsung 21700 inside, but this info did not seem that important to most ozbers. https://www.ozbargain.com.au/node/890654

    btw the negative review for the 25k claiming only 16000mAh 80Wh capacity is stating the output capacity written on the powerbank. I see this on powerbank reviews all the time, a 25k powerbank can never have 25k output capacity it's impossible. there is energy lost to heat.

    some brands won't even have the output capacity printed at least INIU has it on the powerbank. INIU also tested to perform better than most in terms of % output capacity and also input to stored to output capacity.

      25000 mAh @ 3.6 V nominal = 90 Wh
      16000 mAh @ 5 V nominal = 80 Wh

      Always compare Wh. The original review made the mistake of comparing mAh at different voltages, which is completely invalid. Power bank marketing likes to use mAh at internal cell voltage because bigger number; it's never been a reasonable measure (previously all input/output occurred at 5 V, now multiple voltages are supported making it even less relevant).

      80 Wh / 90 Wh = 11% loss, more or less expected.

      • hi I watched a few full reviews from the youtube channel Allthingsoneplace and the 10k and 25k (65W) INIU he tested seemed to do very well in the efficiency loss area.

        he seems to know what he's doing so I trust his calculations are correct, I couldn't remember the exact numbers from memory but after watching again they both achieved ~88% efficiency, which lines up with what you said only ~11% loss.

        the 25k (65W) in particular was able to output constant 65W from full (100%) to empty (0%) which is what I remember I based my decision to go with 65W output INIU Mini.

        hopefully the new 25k 100W output Mini in this deal does just as good. the 140W INIU tested by the same channel did terribly, but I think he got a faulty one because so many things were wrong with it such as not reporting correct % charge and it going completely dead repeatedly until he plugged it into a charger which "woke it up".

      Maybe output-capacity is half-truth ? Maybe DEVICE-charge is more relevant, see extract & link below ?

      Owners of recent INIU 10000mAh power-bank sales @ Amazon-AU: does your power-bank charge your 5000mAh phone ~ 1.2 time, 5800/5000 ?

      'In our tests, 10,000mAh of battery pack capacity translated to roughly 5,800mAh of device charge. 20,000mAh chargers delivered around 11,250mAh to a device, and 25,000mAh banks translated to about 16,200mAh of charge. That’s an average efficiency rate of around 60 percent.'
      https://www.engadget.com/computing/accessories/best-power-ba…

      • Maybe output-capacity is half-truth ?

        I missed the tiny text in brackets it says at (5V) output on the back of mine next to output capacity.

        I asked ai what the efficiency loss estimate of a 25000mAh powerbank would be, they replied (hope I don't make any mistakes).

        For a 25000mAh @ 3.6V battery with 75% battery to device efficiency and 80% conversion efficiency at 5V, the final usable capacity is 15,937mAh @ 3.6V. which just so happens to be the same as the reviewer stated, but it's at 3.6V not 5V.

        16Ah x 3.6V = 57.6Wh
        57.6Wh/90Wh = 64% so only 36% lost I think that's more realistic than 11% loss mentioned in a comment above. so it's close I read good is 30%, and terrible (random cheap powerbank from amazon) can be as much as 50% loss.

      One of the great things about the xiaomi/zmi is that it can sustain 100w charging until empty (could even do 200w too for short periods).

      Most power banks seem to struggle maintaining 100w, like the ugreen one that regularly gets posted here (apparently only does it for ~15 minutes before throttling down to ~35w). Something to be mindful of, if that's important to your use case

      • I would think it would be important for people charging their laptops or anything else demanding. I've tried googling but I can't find anything on the sustained output of different power banks. Where did you find this information?

        • +1

          Just looking at reviews.

          https://www.youtube.com/watch?v=sIgp1jMWUwE

          Whenever this guy reviews powerbanks, he usually makes some comments about sustained discharge, because apparently that's the biggest difference between cheap powerbanks and quality ones

          • @Butt Scratcher: Thanks for sending that through. It's very interesting and I don't know why it's not discussed more. For eg, someone below said they have a Lenovo ThinkPad which needs 65W. If they get a Ugreen (100W or 65W, doesn't matter) that can only output at full wattage for around 15 minutes before throttling down to 35W, then that power bank is only useful for 15 minute charging sessions. If the laptop battery is nearly 0%, a non-sustaining power bank will only buy it a short amount of time before throttling. And then the next question would be how long before the power bank resets and can output properly again. I'm not sure if that person is reading our little sub-chat but it sounds like they need to buy only Xiaomi/ZMI.

          • @Butt Scratcher: that guy reviewed/tested the normal sized 25k 65W output INIU. https://youtu.be/rQ5Fnenxy1g?si=Ex2azD8AWEq1Mj3I&t=207

            it was able to do 65W out from full (100%) to empty (0%). that's what I based my INIU Mini 65W output model purchase on.

            • @n3ck3ntry8bort0rgasm: t's not 100w, and it isn't this powerbank is it?

              He also did also tested an iniu 140w that kept bricking itself and couldn't sustain it. So what is this supposed to tell us about this powerbank in this deal?

              • @Butt Scratcher:

                He also did also tested an iniu 140w that kept bricking itself and couldn't sustain it.

                yes I referred and pointed out the 140W model review was terribly bad in a comment towards the top. https://www.ozbargain.com.au/comment/16406834/redir
                it is likely faulty out of the box, in which case if you bought from amazon would be a instant return.

                if you watch the full review he mentions the 140W INIU would repeatedly not wake and turn the % display on, and it happened multiple times when he pressed the button and the only way to wake it up and get it working again was plugging the powerbank into a charger. this is definitely not normal behaviour for a powerbank, maybe he didn't have enough time or bother to test then get another replacement to test again who knows.

                • @n3ck3ntry8bort0rgasm: From what I recall, it was repeatable behavior. He also said he saw other amazon reviewers who corroborate with the behavior he saw

                  He seemed to suggest that it was bricking itself from running too hot at 140w.

                  You kind of missed my point though.

                  • +1

                    @Butt Scratcher: okay but by your defence in your previous comment, we are talking about 100W output not 140W output?

                    so let's meet in the middle. to me the fact they can design a 65W output powerbank which sustains it's maximum until empty with no problem, means that they have figured out how to design it to do that properly. so the same design can be applied to the new release Mini models I posted in my deal. in the case of 100W output some improvement to allow higher sustained output.

                    until Allthingsoneplace or some other tester with the equipment tests the Mini's 100W output, both opinions that it can or can't do it are invalid.

                    I know the Xiaomi model I linked to in the deal is popular because look how many good deal votes and comments they have while costing $139. Samsung makes the best 21700 batteries on the market I learned that much too. I'm not trying to argue which powerbank is better, naturally you would assume the more expensive one will be better. and obviously the Mini INIU being 58% of the size you would assume some kind of compromise is there.

                    but just from my experience watching many INIU reviews, many of them (except the 140W in particular) actually manage the sustained output consistently. and I mentioned a downside in the deal description, some of them get very toasty when doing it. I suspect this is due to the some of the older normal size models being very thin (less material thickness to absorb away and reduce heat).

                    • @n3ck3ntry8bort0rgasm:

                      okay but by your defence in your previous comment, we are talking about 100W output not 140W output?

                      That's exactly my point, I'm using your comparison of two unrelated products, to show you how it tells you nothing about this.

                      until Allthingsoneplace or some other tester with the equipment tests the Mini's 100W output, both opinions that it can or can't do it are invalid.

                      Wonderful, i'm glad we can agree on this.

                      Because you were trying to make the case that they have a product that can sustain 65w, which i was not talking about and is neither of these models. To somehow make a conclusion on the performance of this.

                      • @Butt Scratcher: okay.

                        Because you were trying to make the case that they have a product that can sustain 65w, which i was not even talking about. To somehow make a conclusion on the performance of this.

                        I did try my best to explain that in my comment above, I made a few edits so maybe it takes time to appear.

                        To somehow make a conclusion on the performance of this.

                        that's the best I can do because there is no test. wouldn't you also assume that "new" models are better than old ones?

                        fyi I actually have a reason to come to a conclusion, because I had a limited budget and I wanted a newer model powerbank. I bought the INIU Mini 65W output version (linked in deal towards the bottom) because I actually thought about it. afaik you neither have the Xiaomi or the INIU in the deal.

                        • @n3ck3ntry8bort0rgasm:

                          There's a lot of emotional appeal in the reasons you are using here. So I want to remind you of what my original point is.

                          Most power banks seem to struggle maintaining 100w, like the ugreen one that regularly gets posted here (apparently only does it for ~15 minutes before throttling down to ~35w). Something to be mindful of, if that's important to your use case

                          Im not saying no one should buy this, or that it is a bad product. I'm saying to be weary if you need 100w sustained performance.

                          Conventional logic says, the smaller something is, the harder it is to cool it. So there is good reason to be skeptical in absence of a review. Especially considering there are many larger powerbanks out there struggling to sustain 100w.

                          There's nothing wrong and i have no issue with the powerbank you just purchased. But you made it out to be directly superior to the zmi, so I wanted to inform people what some of the great things about it is

                          • @Butt Scratcher: ok sure I read reply right above and it makes sense to me.

                            I don't know how common or uncommon it is for a powerbank to not perform sustained spec. but yes I weighed things up and made a decision.

                            I was not trying to make the powerbank I purchased superior to the Xiaomi/ZMI. mine is 65W out max version INIU, not 100W out like the Xiaomi. I was just pointing out how the 25k 100W INIU claims the same performance (in output only actually, not input: Xiaomi does 100W in as well while INIU only does 65W in). and is cheaper and smaller that's it. if claiming it was better than the Xiaomi in every area, I would have made sure to link a proper in-depth test review.

                            also fyi this is ozb so many opinions on deals here I also disagree with. such as anything made by Anker is the best. also the way UGreen has gotten insta promoted to "as good as Anker" when they only just started making Chargers and powerbanks and I read many early 1 star Amazon reviews that stated many issues such as ports dying one by one on their chargers. but no ozb likes cheap and tend to ignore the rest. there were those built in cable 10000mAh powerbanks posted recently for $10 each with completely unknown brand name and questionable battery quality, but ozbers loved those posts.

                            tbh that was my original opinion on INIU because I heard about overheating and pouch cells. but my opinion has turned around a bit after people telling me how impressed they are irl and also the mostly positive opinions you read online. so imo I was confident enough to give it a chance. if you really were thinking about getting a INIU or not, maybe consider that if it doesn't perform 100W sustained like you need, if buying from amazon likely they will side with you that the "product is not as described" and you can get a full refund.

                            • @n3ck3ntry8bort0rgasm:

                              NO you should NOT ASSUME anything about any new products OR any new tech advancements that comes out until there is real world tests or real world users buying the product and posting their reviews..

                              These high density battery mini power banks are considered new tech advancement products.

                              If you been around long enough you would have seen new tech products OR new tech advancements that came that had problems that were not found in QA testing by the manufacturer.

                              e.g. Samsung Galaxy Note 7, apple bendgate + antenna gate,
                              https://www.google.com/search?q=tech+products+that+were+reca…

                              Also never trust anything manufacturer claims on their specs until there is real world tests to see if what they claim / market / advertise is true

                              e.g nvidia 50xx series claims about performance vs 40xx series

    • does inui use Samsung 21700 or what brand?

  • +5

    after buying their smaller 10k carry, i am a massive fan of this brand now. the quality of their products are extremely impressive!

    • +3

      Second this. Never had an issue with INIU over a ~dozen products.

      • Except those hardcore Xiaomi or Anker fans seem to have problems with INIU.

  • https://iniushop.com/en-au/products/iniu-p63-e1-power-bank-s…

    Seems to be 65w input / recharging according to the images on the top of the product page linked above

    • I see conflicting things. It says 100W in images. Only when that one port is outputting.

      • +1

        yeah it does 100W output with only one port used.

        desty is talking about input (charging the powerbank), it's 65W max.

    • +1

      Seems to be 65w input / recharging

      yeah I mentioned that in the post. reason being I have the 20k and it it's input is 45W.
      so the 25k has 100W output but pretty sure only 65W input (charging the powerbank).

  • +3

    Haven't purchased an iniu product for a while but was happy they sent me a cover for powerbank purchases via Amazon.

    ( stretch fabric) less slippery.

  • Damnit. Literally purchased two of the power banks in the comparison image last year, now I want to swap them for these due to weight and size when travelling overseas.

  • Wtf so smol

    • But so strong.

    • That's what she said

  • How does INIU compare to Anker/Ugreen/Xiaomi?

  • +1

    I have the 25000mAh 65w version of this one, it’s been a champion for about 3 years for me now.

    This one appears to be about 2/3 the physical size.

  • This may be a dumb question…
    I recently got a refurb thinkpad, and I'm looking at these for keeping the battery up.
    If the charger is meant to be 65W would the laptop still charge correctly with a 100W power supply?

    • +1

      I'm still having a bit of difficulty understanding what you mean in your last sentence.

      does the laptop charge with USB-C?

      if it charges USB-C 65W yes 100W charger/powerbank is perfectly safe. if it's limited to 65W it will negotiate 65W maximum and charge the same speed as your thinkpad charger. if the laptop is also 100W USB-C compatible then it will negotiate 100W and charge faster. there is no issue.

      just make sure you are using the 65W labeled USB-C port on the power bank, as the other USB-C port is limited to 36W.

      • Yes sorry should've been more clear!
        Charging with USB C - sounds great!

  • Their website has the same version but with an USB-C EDC attachment cable. I think that Amazon version is "without cable" (it comes with a 30cm cable, but I think that's just a standard cable not one which you can attach to the battery)

    https://iniushop.com/en-au/products/iniu-p62-e1-power-bank-s…

    Unfortunately the website is showing out of stock. Note that you can get a 15% coupon for signing up once they are back in stock.

    • +3

      ok I'm an idiot. this entire time I thought the lanyard thats attached out of the box is just a nice lanyard.

      turns out it's a 20cm USB-C to C cable. so yeah amazon ones come with it as well.

      • Oooh awesome I'll buy it. Thanks for the confirmation!

        • @RayEarth2133 did you end up getting it, and did it turn up as the “with cable” version? Amazon review pics suggest not. Thanks for your comment either way

          • @ramezemar: just a fyi RayEarth was asking about the P62, which is the 20k version Mini.

            it is also the model I got from amazon and yes it includes the short C to C cable.

            the 25k version in the main link in deal post is the P63 and I can't comment whether it comes with cable or not.

  • does anyone know what is the limit for bringing these chargers on a plane?

    • According to a quick google search, this is roughly the limit.

    • No limit to chargers.

      Limit on batteries are generally 100wh. This is under that (Wh = (mAh * V) / 1000)

    • +3

      100Wh was the size limit until now. the power bank in this deal is 90Wh.

      but I read a few comments recently on ozb that said certain airlines are changing their rules. so maybe google search the rules for the particular airline you will be using.

      tbh I don't travel much at all so that's all I can help with.

      • 160Wh on Scoot and SQ. But as of this month you are not allowed to actually use it inflight.

  • I bought this last week for $99. It's unopened and I can return it, but as it's not sold by Amazon themselves there's a $7 postage fee. Not sure I can be bothered returning and reordering just to save $8.

    • +5

      I think your time and effort would be better spent elsewhere.

      • Sir, need I remind you this is OzBargins

    • That is a successful return fee. It’s really wasteful to do stuff like that. They should just refund the difference seeing as you noticed in a short timeframe (I realise Amazon don’t).

      • They use to refund a long time ago.

      • They probably figured they save money this way as way less people would bother returning stuff to save a few bucks as that involves going to the post office compared to being lazy on the couch and asking for some money.

        • Yeah agreed. But, most people probably wouldn’t notice. It would be a great policy if they had it. Pretty sure eBay offers something like it.

  • after trying the Ugreen and Xiaomi I am an Iniu man now

    • Why? What makes it better than Ugreen and Xiaomi?

      • He obviously just likes it iniu for some reason

    • @CoolHwip74, @Save 50 Cent, @ocular

      Maybe people should be brave, provide details, be as factual as possible, regardless of neg & contrary replies ?

      Maybe OP is referring to recent purchase of 10000mAh power-bank for $13 ? https://www.ozbargain.com.au/node/899350

  • +1

    There's also this one which is 140 watt output. $110.49. Or the 27000 one for $120

    https://www.amazon.com.au/dp/B0CB1CCQ5P

  • While this thing is certainly smaller than the standard equivolent powerbank (my Cygnett 25K is 18cm), they must have a hand model with some mighty large hands. If the device is 11cm tall, then her thumb is over 8cm long. My thumb is 6cm long, so arguably her hands are 30% bigger than mine…

    • I have the 20k which is only different in cm thickness. I held it the same way and it does look very similar.

      maybe a trick of editing and photography because when I hold it that way and then remove the powerbank my thumb actually starts much further up, like imagine 2cm from the bottom of the power bank behind that your palm is still behind it.

      they might have used the 20k model for both 20k and 25k photos though because mine looks as thick as the 25k photo.

  • Really tempted for traveling later in the year…just wondering if I should hold until EOFY sales to see if it'd go down in price further.

    Got enough powerbanks lying around the house otherwise lol…

      if you want my opinion you should get it only if you will use it. it's not good to just let powerbanks sit around and do nothing. worst case you charge it to around 50% to minimise wear in storage and repeat. but then you are charging it and putting energy into it for nothing.

      I even remember reading a comment about the $139 Xiaomi, they complained of high self discharge and it not being able to charge things when they decide to use it. imo they must have just let it sit for a long time. if you are regularly using and charging it you will always know the state of charge and have it ready to use.

        Totally agree man…I might just hold on and pick it up later in the year before I head off overseas.

        Won't let FOMO get me this time lol.

  • bought for my trip to japan in may with my partner and two kids…lots of devices to charge!

    • with that many people and devices, you need at least 2 or more powerbanks

    I opened the INIU website for the same one and saw a 15% off welcome offer on its $89.99 price, but closed it and then 30 or so minutes later i get an ad from facebook offering 20% off with code "STAY20", so it might be cheaper that way - my checkout price is $71.99

    • There is no stock?

      That's for the 'Classic Model' this is the 'New Release' which is out of stock on the INIU website.

  • cheers took for 71

  • If you're wanting something similar size/weight that can do max 145w (140w single port) check out the Move Speed M25 Pro. It's about $75 shipped on Aliexpress

    • not a well known brand from aliexpress..

  • I have the current one. This one is 20% lighter (~100g) and 4cm shorter. Same width & depth. Should I? Do I?
    My INIU has been faultless. All the others I've had haven't lasted.

  • I was going to buy the 10K one but it's not really good value at $49.99 including the 15% discount. Hoping to get it for around $25-35 sometime.

  • I have the 10k version and now after about 30 cycles, it only ever charges to 92-96%, don’t think that’s normal for such low cycle count. YMMV

    • Which 10k version is this?

    • it only ever charges to 92-96%

      ~ 30 cycles seems short for battery degradation & internal structure damage.

      Did you,
      1.allowed it to drain to 0%…& left it in that state or low battery-level, say 10% for an extended-period?
      2.fully charged it to 100%.
      3.full & candid disclosure of your circumstances…extended-use @ high-temp, it got hot?

    • Weirdly, it's still available to buy on Amazon…

      Any ideas?

      • I tried reordering it I noticed the new listing wasn't combined with the regular one so who knows…

        • I tried reordering it I noticed the new listing wasn't combined with the regular one so who knows…

          weird. read my comment below. seems like they can't make up their minds which listing they want to use. or maybe a bunch of people clicked the cheaper option and complained when they got the normal sized version. 🤷‍♀️

        • Listing is gone now

          • @wombat81: Still haven't got the second cancellation, will wait to see what happens. Fingers crossed

      • I have no idea. I got mine a few days ago, because the price was pretty low for the 25k I waited a few days before posting just in case price error. so I assumed this deal was a go.

        but I remember planning to buy it a month ago and them taking down a previous listing as well before I could click buy. that listing was for the product on it's own, so I would think this time around they combined the Mini as a option on the listing linked in deal and it was officially available?

        • I mean I didn't really neeeeeed it but I did want it, so I guess I'll hope for the second order but realistically will need to wait for them to list it again I suppose.

    • Yes I came straight here lol

    • Yes. Very odd… unsafe maybe?

      • but it happened (at least) once before when I was checking it. they took down the listing. so if unsafe, why put it back up again?? 🤔

        • Hand a random thought. Could it be d****s returning the item and saying it is “faulty” to get a refund? To avoid return shipping fee? And Amazon has a system that when X amount are returned they pull a listing until seller investigates or whatever? I’m sure they wouldn’t want to mess around with bad battery packs.
