added to OP, thanks,
How fast would it charge iPhones?
Depends.
Not sure why they are negging you.
It really does depend.
- What iphone model
- What cable is being used.
- How old is the battery.
- Charged while being used or on standby?
- If any apps and other things are turned on at the same time like Wifi, bluetooth etc.
Probably because he just said depends and nothing else of value.
@smartazz104: Original commenter asked a question with none of the detail required to give a valuable answer.
In addition to the list above:
- What the current % of charge is.
charge iPhones?
- How many iPhones you are charging at once.
The list could go on and on. In summary - it depends. In further summary - you ask a dumb arse question you get a smart arse reply.
@MS Paint: Okay.
Sorry about the “dumb arse question”.
iPhone 11 Pro, so what’s the answer, smart arse? iPhones don’t support QC so I assume they would be charging at the same speed.@mrgeckoz: Thank you for providing me with the opportunity to answer your question.
Assuming the battery is totally flat it will take approximately:
- 30 minutes to achieve 50% charge
- 60 minutes to achieve 85% charge
- 136 minutes to achieve 100% charge
I hope this has helped and that you enjoy the rest of your weekend.
@mrgeckoz: the downside with the cheap chargers is usb a ports so limited in how fast it charges apple vs usb c charger and usb c to lightning ……
i find these chargers are handy for table lamps and stuff that now need you to supply own charger instead of plug packs and still use usb a cables …..
@mrgeckoz: Your comment is correct. With USB-A, it is impossible to operate in USB-PD mode because USB-A lacks a pin that only exists in USB-C to perform USB-PD charging negotiation. To make the matter worse, this charger's old chipset doesn't even support Apple's 5V 2A protocol, which meant it has to fallback to the basic 5V 1A mode when used with Apple devices.
@MS Paint: Regrettably, what you calculated is incorrect, please see my comment below with full explanation and what the 18W charger is capable of when used with an Apple device. P.S. I do not neg OZB comments (even if the comment contains incorrect information). This one is tricky because if you don't have a USB meter, you cannot tell.
Apple users, the 18W charger would operate like a 5W charger on Apple devices.
If a mod is available / online, perhaps put in a comment that the 18W charger is only able to operate in 5W charging mode (based on testing from a user who own the 18W charger purchased from a past deal). The 18W charger is really only suitable for Android devices.
@netsurfer: Thanks for the clarification. Much appreciated. Finally someone gets where my question is coming from…too many smart arses here now.
Because he gave a dumb answer. All the criteria is irrelevant. 99% just want to. Plug it in and leave it, not all the other silly options. Just a general time from flat would have sufficed.

Please add more value to your response EC 😉
At least it's an answer not a question
if you check the pictures it can provide: 5V @ 3A.
So this charger will charge any phone faster than using a 2.1A USB charger.
Incorrect for at least the 18W version. That's because Apple requires the charger to support Apple's own 2A or 2.4A 5V protocol. Regrettably, the charger's chipset is NOT coded to support it.
So this charger will charge any phone faster than using a 2.1A USB charger
That's also incorrect. The phone (the device receiving power) decides how much current to draw. Otherwise, if I use a 100W charger on a laptop that supports only 30W, it would fry the laptop.
There is actually a bit more than meets the eye with cheap chargers with old chipsets. Old Samsung and Apple chargers do not play nice to each other. The 18W version does not play nice with iPhones.
You should NOT get the 18W version for iPhones. I don't have the 30W version to check.
The 18W version is USB-A and is coded just enough for Android phones. It does NOT support Apple's old faster charging (i.e. 5V / 2A to 2.4A). So, when using it, you are stuck with 5V * 1A (5W charger). For Apple devices, this is basically a 5W charger. I have tested it just now (an iPhone which has only 37% battery so fast charging, if supported would be used) with a USB meter to confirm. The meter reported no Apple 5V fast charge support (which I was surprised, and I double checked the actual mode when charging, stuck at 5V 0.98A). As soon as I changed to even my old Apple 10W charger, meter reported 5V ~2A with the original Apple charger.
Being a USB-A charger, it does not support USB-PD so it is impossible for it to support fast charging on Apple or Google branded phones.
As for why I never bothered with the 30W version. Zero of my old micro-USB phones supports QC2/3 @30W. Majority of my phones use or support USB-C/PD charging. As for the pack of 3 I bought, they have been collecting dust. These are not versatile and are for Android phones only (it does support Samsung's 5V old fast charging protocol, pre-QC; and obviously, it supports QC so newer Samsung phones would elect to use QC with these).
Charging modes supported by the 18W charger:
- 5V 1A (fallback, no specific charging protocol) : This is the only mode the 18W charger is able to operate with Apple devices
- 5V 1.2A DCP : Android devices pre-QC
- QC 1.0/2.0/3.0 5V, 9V, 12V - Android devices supporting QC1, QC2 or QC3
I have checked multiple times with Apple devices. Even if the charger defaults to 5V 1.2A DCP, as soon as an Apple device is connected, it drops to default fallback 5V 1A.
Do not assume 5V 3A would just work on any device. Likewise for 9V and 12V. If you don't know phone / tablet charging protocols, talk to your mate who knows first.
If using these to power raspberry pi's - any advance in the 30w vs 18w?
Pretty sure the included charger is 18W so no advantage. I don't think the Pi can draw more (could be wrong though). Best to check site
Thanks :) (yes I meant advantage, thanks for picking up the typo)
It has multiple usb 3 ports itself which can draw plenty of power
Zero advantage to this. Power draw is tiny.
For a pi, what you really want is a charger that accurately outputs 5V. Many USB chargers give slight below 5 leading to power warnings and more rarely to a throttled CPU.
IIRC my Pi 4B is drawing 5V 3A = 15W. So
RPi 4 - no point getting either of them.
RPi 3 or below - basically, at best a 12W charger (regardless of which one you get) but none of them supports 15W anyway. Worst case 5W charger (too lazy to check, but if enough people are interested, I could check it on my old Pi zero (it is collecting dust somewhere, I need to find it first).RPi 4: with USB-A, it CANNOT draw 3A out form 5V. There are multiple factors making that happen. 1. It is against spec; 2. It requires QC2 or QC2 (against official USB-A specs) and RPi 4 does NOT support QC, it doesn't even support proper USB-C PD. 3. The cable (if legit) wouldn't allow that to happen.
The only reason you get these is if you, for some reason, needs 2 or 3 dirt cheap chargers.
I could check it on my old Pi zero (it is collecting dust somewhere, I need to find it first).
All good, I've got a 1st gen Pi Zero W with a USB DVB-T adaptor (running piaware) on a 1a 5v power supply no probs
Does anyone know if Xiaomi makes any QC4.0/PD3.0 compatible adapters? Can't seem to find any good bricks on ebay that don't look dodgy
Hmm what charger to get for the s23ultra? Seems it can do 45w? Coming from an S10+ its a bit of a change.
Where does it say it can do 45w?
I'm also looking for a deal for one. Currently I have two 3rd party chargers and a Samsung one that does super fast charging.. If I'm not mistaken, being PPS (programmable power supply spec) capable is the requirement.
So if the charger is advertised as PPS capable (and 45w+), it should work.
Simple y/n…
If I use one of these with a 100w baseus USB C cable to charge my pixel 7, will it say 'charging rapidly'?
Yes, Pixel 7 uses QC3.0 and it charges at 30w.
Y
No, these chargers are USB-A ports and Pixel 7 will only fast charge with a USB-C fast charger.
They are crap. I had them and thrown them.
I was thinking to buy one, what's wrong with these?
They dont fast charging. I have other fast charging 20w adaptors, they work better on Samsung phone. Also they are huge compare to other adaptors, so it gets difficult to use them along with other adaptors or in power board
You can buy them and if you are ebay plus member return them for free if it doesnt work for you.
That's a no brainer. A 20W charger will be faster than an 18W charger.
30W is for Xiaomi Turbo Charge and Samsung isn't Xiaomi, so 18W it is.
@Clear: It does not charge fast at all. At least not for me. Using the same cable it was charging at slow speed and Samsung phone would not also display fast charging.
@BargnHuntr: Which Samsung phone? Unless the latest ones have removed it they normally have Samsung Adaptive Fast Charge which is a rebadged QC 2.0.
Buy now - think later.
I still have 2-3 samsung charges before they made them separate. Are these an upgrade?
this isn't usb-c?
no
The POCO M5s super-charges with the 33W charger that came with it; is the 30W one here strong enough to super-charge it too?
Is this type c
good deal
What’s better 18W or 30W for iPhones? The latter will cause over heating if too fast?
your phone will decide how much power it wants to draw ….advantage of 30w chargers is hopefully higher spec components ….so if phone is just charging at 18w hopefully charger runs cooler vs 18w charger which is maxed out ….. down side of 30w charger is bigger and they way they fit on power boards can make it a bit of a squeeze vs 18w which are smaller ….
none, both would be at 5W speed anyway.
Will the 30W charger charge the Samsung Galaxy S23 at the highest charging rate (25W)?
Yes.
No it won't. It's not a USB-C PD charger.
will this charge fastest speed on samsung S21 to S23 phones?
Yes.
S23 ultra can charge at 45W.
Still looking for a 30w charger with dual USB3 and USB-C ports.
Now that would be a ball-tearer…
I have the 30w of these and they are slow in charging ipad. Not sure why
read the comment above
The iPad doesn't have Qualcomm Quick Charge (18W) or Xiaomi Turbo Charge (30W). That is why.
Our iPad mini 2's original charger is 10W.
thanks
This is all too complicated, Got a Xiaomi Redmi Note 10 Pro, so what cable do I need to get for fast charging with this charger? Scored a Qualcomm 3.0 charger with integrated USB-C lead when touring Japan. Even with an adapter for the 2 flat prongs this has been such a convenient charger for travelling, but need a spare. Why don't we see plug packs with integrated usb-c leads?
Got a set a few months ago.
Not, when plugged into a standard double GPO (power point) it's so wide, that it isn't possible to plug anything else in at the same time.
FYI.
I received mine 30w ones today, it doesn't say on the adapter that they are 30w
Same here.. i am wondering if we are given the 18w ones.. because the same seller now have 18w listed for $16 which was the price of 30w ones as per this deal.
I received my charger today and they are not in packaging, so can't really make out whether they are 18w or 30w charger. Also charged my Pixel 7 pro, it is not saying "charging rapidly", whereas with 30w PD charger P7P says "charging rapidly".
30w $16.8
