I been looking like crazy and all I found were as high as 850mAh for the Droid Charger. Anyone found any other than the Stock Charger?
I use an old Nokia wall charger. The output is 550 mA. It works just fine. The way I see it is that its a higher output than just charging it through a computer and less than the stock wall charger.
The slower you can charge a Lithium-Ion battery, the better.

I need the faster you charge the lower the charge and wears out battery faster
if you do want a FAST Charge, then you got it with high output it'l kill your battery but.. there is an upside.. if you charge on fast charge..
then drain it 15 precent charge again you'll have similar effects of a long slow charge
The Apple charger is a 1000 mAh charger.

apple phones also have crap battery time
I use an old Motorola charger because the cord is longer... charging it on the computer USB takes FOREVER!!! It is from a ROKR E8 and I think it says 650mAH The stock charger that came with the Slide is 1A and my GF's charger for her CLIQ XT is 850mAH.....
I use them all, does it really make a difference?
And how so I condition the battery because I get horrible battery life
I recently bought a 1900mAh anker battery for the Sensation and I plan to use it for my Amaze.
On the battery it says that the limited charge voltage is 4.2V and on my charger it says that its output is 5V. Does this mean that I should not charge my anker battery with my charger? Or will it be fine?
It will charge fine. I have 2 anker batteries.
Our x10 don't support powerbank charge right?

As long as the charger can charge lithium polymer batteries at 3.6 and 3.7 volts as well as fit the actual battery. Then yes.
I'm using an external charger myself: PowerBase C-734U. It takes all kinds of batteries, and I charge most of my Li-Po and Li-Ion batteries in it.
I have a battery charger for my lipo batteries that I use in rc helicopters. I was wondering if I could use that charger for charging my gtab?
Hey, is it safe to use original 45W Samsung charger daily? Got it for nice price ($25) from friend's shop.
I read somewhere it's not recommend to use 45W. Also I read S20+ supports 25W only.
Thank you for answers.
It is safe to use the charger but I am not sure if it will be able to charge it at 25W also.
So if I will use 45W, charging will be the same as with original charger?
Tried it, remaining time to fully charged is showing the same with both chargers.

I have the 45w charger. Charging speed depends on the phone temperature. The phone slows down the charging when phone temperature gets high. It's marginally faster than the one that came with the phone. But it's super fast charging for the first 30 minutes or so compared to our of the box.
So i use the 45w charger at office when I need to charge the phone fast and seldom fully charge it as I would unplug it and go somewhere else.
At home I just plug in the charger that came with the phone for overnight charging. Perhaps not the best to leave it charging overnight but I need a full battery next day.
Even if the charger provides 45w, the phone will only pull what is needed from the charger itself. So if the phone limits itself to 25w, then thats all it will use from the charge available.
Equally, if the charge provided is lower than the maximum the phone can use (i.e. 25w phone but 15w charger), then it will use the maximum from the charge available.
Chargers these days offer a multitude of different voltages and amp ratings, but they are smart and will only send what is requested by the device that is plugged in so there's no chance of accidental over-voltage.
I too have the 45W samsung travel charger and did a comparison on power draw compared to the 25W charger that is included with the phone. I used both the USB C cable that came with the phone (Black) and the thicker cable that came with the 45W charger (White), while measuring the power draw using a power consumption meter that was plugged into the wall between the charger and the outlet. My phone was at 40% charge when I tested. The results are shocking.
Included 25W charger
Phone's Black cable - 27.9 W
Charger's White cable - 27.2 W
Samsung 45W travel charger
Phone's Black cable - 29.7 W
Charger's White cable - 31.3 W
The similar power draw explains the charging speed difference of 10 minutes which many reviewers on youtube have observed. Taking another step, I have read that the S20 Ultra requires the charger to support PPS to achieve (10V, 4.5A) in order to charge at 45W. So why does the 45W travel charger only support (15V, 3A), (20V, 2.25A), (3.3-11V, 4.05A), (3.3-16V, 2.8A) and (3.3-21V, 2.1A)? Even the best case scenario would be to use the (3.3-11V, 4.05A) PPS profile and set it to (10V, 4.05A) to give only 40.5W. I smell a rat.
Interesting. I have also measured power draw but my results are bit diferent.
45W charger was getting up to 41W for 4 mins.
On overall charging speed 0-100% the diference is 10mins, but after charging 20mins I'm getting 54% on 45W and 37% on stock.
17% in 20mins it's a lot of difference.
45W is slowing down up to 1A after that to cool down the phone. 25w have similar behaviour.
Baseus 65W PPS chargers triggers SFC 2.0 but it takes more than 2h to charge fully. Amperage is oscilating as hell.
my Huawei 65w laptop Charger charges my S20U much quicker than the 25w charger i find...

I have been continuously testing and found that if your phone has less than 30% battery and the battery temperature is under 33 ºC, it will charge at 40W. After that, it drops to 30W for the remainder of the charge and then drop again to 20W when the battery is above 80%.
Next step is to find a good battery data logging app which logs battery percentage, battery temperature, charging current and time. Surprising to find that not many apps can do this. Even the Battery Charging Monitor app doesn't log all that data.
