Today i ordered a QI fast charger pad from Anker powertouch 10
I was wondering would it be possible to charge using wireless fast charge pad & usb to micro usb from the mains plug to get a superfast charge at the sametime or would adaptive charging from the device be smart enough to only draw 2.1 amp to stop a melt down, what takes priority if i had my phone on the pad & mains plugged in or would it damage my device, also is it true wireless charging is better as there no ramp up to max charge,
my local repair shop told me that when u plug in a fast charge wire it can take 5-10 minute for adoptive charging to request full 2.1 amo from the mains

Hi Here in Mexico dont have a UK plugs and of corse my phone charger dont fits o the outlet but i have a USB Charger I can plug the Data cable to carge but the only question i have is this specs
Samsung Original Travel Charger is output : 5V = 0.7a
My USB output : 5V = 0.5a
Please Help
I think the only diff is the charges Times is less amp takes more time to full the battery.
i use the uk charger here in the u.s. i believe they are set for multiple power inputs just get a cheap adapter to change the plug configuration. that is what i am using.
i posted the below in another charger thread but in case it serves here
not sure if a lot of folks are just unaware, but every phone i've had charged fine from a usb port off my computer
since i started tethering my phone to my laptop (browse the web from family couch) december 2009, i haven't used the wall charger
even if i'm not tethering, i've got a spare usb cable on the desktop, that when i sit down at the desk, the phone or whatever device, gets connected to - far more convenient and fewer items occupying space on the desk
plus, i've got that Tmo car charger that just has a usb port on it's end - so the same cable that i use to tether to the laptop (when in the car), if i'm using the phone in the dock for nav, runs down to the charger - the charger, with no cable hanging off it when not in use, let's me leave the charger in the socket 24/7 - no looking for it in the glove box and untangling it etc
that charger is simply converting the 14V car voltage to 5 V the USB port normally delivers
2 - 3.5 hours seems to take my 1150mah battery from low charge to full
for what it's worth

There is nothing wrong with that. 5V is all you need. As long as you don't supply too high a voltage, your batteries should be safe. Don't worry about the amperage (current). Lower current (0.5a vs 0.7a) just means that it takes longer to charge the batteries.
And for those who really must have a wall charger that charges the batteries directly, you can buy a universal USB charger (http://www.dealextreme.com/details.dx/sku.15264). It works great. It plugs into any USB charger or laptop USB port, and charges any battery rated 3.7V. You can find them on eBay for just a couple of dollars.
On the Samsung Galaxy Note 2 (basically all Samsung Galaxy device), their two data pins on the official charger are shorted to be verified as a official charger and enable fast charge. If I connect it to a no-branded usb 12v charger, it takes a very very very long time to finish charging (like 5 or more hours bevause it only want to recieve 350mA rather than the higher rate on the official charger). I remember I dont have any problem charging my HTC Desire HD with the Samsung charger. But if I use HTC charger on Note 2 it also needs hours and hours to charge.
My question is what brand/model uses the 2 data pins to verify (or know how to charge when they are shorted) so that damage will not occur. Anyone knows the answer?
Several things going on here. There is a difference between USB and AC charging mode. I have had to short two wires in my car adapter to get my Nexus 7 to start charging with AC mode. Don't assume that every charger is capable of charging at the same rate. If you have a 350 mA charger, it won't charge your device as fast as a 2A charger.

I didnt mean that every charger can charge at the same rate. I wanna modify a 2A charger but I'm scared that if I unexpectedly connect it to an incompatible phone and something bad will happen. If a no-branded charger (data pins are not shorted) is connected even it's on the wall plug, the device will set it as USB charging and lower the receiving voltage so the device will charge very slow or the battery percentage will be dropping even when charging while using. My HTC charger can charge the phone that it belongs (Desire HD) in 2+ hours but the Note 2 needs 5 hours (this means that the HTC charger has no shorted data pins). And the Desire HD wont get an error when using a charger with shorted data pins (Samsung charger). What I want to know is what phone cannot be used with a charger with shorted data pins in case someone (or myself) use my modified charger to charge a incompatible phone and let damage occur.
Hi,
I have a Z3 and was wondering if I can connect my magnetic charging dock to a Quick Charge 2.0 charger? Will it work as a normal charge, quick charge, not charge at all or burn out my phone?
No it is not it will charge as a regular charger because the phone is not giving the permission to the charger to give more energy. Quick charge it uses all 4 wires within the cable to communicate with the phone and magnetic charge is using only two, so it can't communicate with the phone, other than just giving it charge .

QC2.0 will work with normal usb cable, and DK48 dock. Unfortunately it doesn't work on standard magnetic charger like magnector and etc.
I have an s7 and I was curious if anyone knew whether you could use a qi wireless charger and wired charger on a s7 either with some sort of application or otherwise to effectively charge it from both sources simultaneously to boost charge speed and if anyone knew of a battery case that can be charged by qi wireless charging and can use qi wireless charging to charge the cellphone once it was disconnecTed from the wireless charger so that I don't have to plug my battery case into my s7 and can just keep the usb port free.
Just tried it. The phone uses whatever charging method was connected first. If it's on the wireless charger and you plug in a cord, it ignores the cord. If it's charging wired, and you set it on a charging pad, it ignores the pad.
Samsung makes a battery back that will charge the phone wirelessly. I haven't seen anything that indicates whether the back can be charged wirelessly or not. Reviews seem a bit mixed:

So, when it is about charging, this Galaxy S21+ (Exynos) can be really choosy. With a lot of chargers, it difficulty reach 1.3A. Only few of the selected chargers (my Lenovo 65Watt laptop charger, IKEA 27Watt charger) it could reach 2A charging with wired. For wireless charging, it's even worse. Currently I owned 3 wireless chargers.
1. Energizer 15Watt charger. Never even shows Fast Wireless Charging.
2. Samsung EB-U1200 Wireless Charging Power Bank. This one shows Fast Wireless charging. It could charge up to 2A for a while and then once the battery temp hits about 39C (and it hits there within 5 mins), it throttles.
3. Huawei SuperCharge 27Watt Wireless Charger (with Huawei 22.5Watt SuperCharge Charger and 5A cable), performs same as Samsung Power Bank. Reaches up to 2A, then battery heats up and throttles.
I've tried different ways, including removing the phone case while charging but result is still the same. Does any of you have similar experience? or is it just my phone? Please advise me how to make wireless charging more efficient.
I've not tried wireless charging however for wired you need a charger that supports USB C PD PPS (this is a fairly new standard) and without this you won't get anything more than about 2A.
This Ravpower charger for £16 (£13 with current voucher code) works a treat hitting 4.6A when the battery is empty reducing as the battery becomes full. You have to use USB C to USB C to achieve this.

My guess is there will be a similar standard for wireless charging that you need to adhere to.
