With Qi charging is it just a case of using a 2A power brick and enjoying charging at the same speed as a 2A (iPad) charger with lighting? Or do you need to make sure you’re using a particular Qi charger?

Can you put the 29W charger into Qi?
 
Quick-Charge 2.0/3.0 is not the same as plain high-amperage supply. There may be some logic built into it. I'm not the expert in this, so could be wrong, but if there is a standard named, it's safer to make sure that requirement is met.

Most reviewers seem to recommend RavPower, including TheVerge. The thing is...on Amazon, it would be CAD$82 by the time it's delivered (taxes, shipping, customs). So for CAD$90, I decided the Mophie, which is endorsed by Apple and is available locally, was my pick.

I'm going to be experimenting with some no-name standing docks though, since it would be better/easier for FaceID. Currently looking at This one.


Here's a some info.

I bought a no-name charge on amazon that doesn't work. Placing my phone on it I come back and notice my phone has slid off the charger , the heat most be making it move and the surface is not strong enough to prevent slipping.

I don't really want to pay $60 for a charger, so may give one of the anker's a shot or not use wireless charging at all.

I think it's better off getting one that comes with the wall plug instead of having mixed results with your own

I’ve got this which is good (and was cheap) but keen to get something faster if it is out there, or at least learn how to make this as fast as possible, hence the post

2A Charger required. iPhone charger is 1A. That’s why some people seem to have problems with some of these QI pads. They are not using the correct plug.

Never had an issue with it not working, works like a dream. Just prepared to pay for something better if it’s out there

Why do you need a 2A charger? Current wireless will only charge at 5W so a 1A should be enough. Is there some loss due to the wireless system so you need a higher current at the source?
 
So I guess this is a bad idea? Was thinking of about 5/6 for around the house little DIY project for the weekend?

Why is it a bad idea? It’ll charge at 5W which is the same speed as the charger that comes in the box. Not as fast as a 2.4A charger or iPad charger, but wireless is about convenience more than absolute speed right now

I’ve seen several of these on Amazon where the seller/manufacturer says to only use with 2A. There is a difference between watts and amps, but I’m not an electrical engineer. My simple understanding is that amps allow more of charge to pass quickly to make up for the loss of watts due to inefficiency in wireless chargers.
 
Well if you buy the Mophie one when Apple enable wireless fast charging the cable that’s including will allow for fast charge

I bought one from Anker, which supports the normal 5w charging, and fast wireless charging which is 10w, and to get fast charging i must use a quick charge 3.0 power brick, anything else should work for the normal 5w charging

True, but the 8/8+/X will never use 10w. The max they will achieve, after an update, is 7.5.

Yes that’s what i heard but it might be useful for other phone in the future or future iphone model, who knows...
 
I bought the Mophie one from the Apple store, yes it’s expensive but I thought firstly I’d treat myself and secondly that if Apple endorse it then it’ll be good quality and support fast charging later in the update. I could spend £20 a few times to try and find one that works right or £54 for the Mophie which works great.

What I can’t understand though is why are the iPhone X and 8 series limited to 7.5 watts when I read Qi goes up to 15 watts?
 
I have the Mophie and found it to be inconsistent. Placement must be precise or it either will not charge or alternate between charging and not. (Blinking green light as opposed to solid). I’m going to most likely buy a cheaper Qi charger from Amazon and return this one.

im curious about this as well, the adaptor apple gives is 1A, a lot of these chargers if you buy without an adaptor require 1.5-2.4a adaptor. The Choetech T511 i bought says that in the book. Also a lot of these chargers im seeing that come with adaptors are all 2A

i should mention that when i use the apple 1a adaptor with the qi wireless one i bought the adaptor gets hot to the touch after charging for a while

So will the Anker not charge at 7.5 when the update happens? Is this model ONLY 5 OR 10W, or is it a range of 5-10?
 
It's not an either/or situation. It's an "up to" scenario.

Ok, so the Anker seems like the best bet, no? Buy the Anker pad now at $25, when update comes from Apple, buy the Anker plug for $15 as well. Cost is still less than Belkin or Mophie.

Just buy everything now so you will be ready when the update comes out. I think the anker one is the best looking one also the smallest, i love it
 
For what it’s worth, I bout this one for less than $14 on Amazon, and it works great overnight:
https://www.amazon.com/Wireless-Cha...coding=UTF8&psc=1&refRID=7YAPVMB32329T2KP3KS6

Like some of the others, it specifies a 2A Charger, so I’m using a spare iPad charger with it.

so basically if its above 2a u can use any charger? my ipad charger is 2.1a, maybe thats why my 1a apple charger gets hot when connected to my choetech wireless charger ( says 5v-2a on back of the pad)
