You are so on point I got that NEW AGE ENEGIZER it works like magic too fast! I got it 1k I thought I was wasting money!

Greatzeus:
My lenovo A5000 charger's output is 5.2 V ---2.0A.
Its so fast charges my 4000mah battery in less than 1 hour from maybe 15% to 100%.

That is a tablet charger and not suitable for many phones. That 5.2v is too much for most smartphones. Yes it will charge ur phone faster because it is 2.0A but ur phone might not respond properly to touch while charging and this might have a lasting effect on ur battery. I have a galaxy note 4 charger rated at 5.3v 2.1A. Whenever I use it on htc one m7 or other phones the screen doesn't respond well to touch while charging. U can touch the recent button and it will launch the camera. It also does this with my Innjoo tablet. Although on some phones like the s6 it works perfectly.

In a nutshell, it is not the voltage that determines the rate of charge, it is the ampere ur device is able to draw. In this case the charger is maxed at 2 amps which is fast for most devices. But if ur device is rated at say 1.5 amps, then ur device will regulate the amp to 1.5 amps and not the whole 2 amps.

OP, Don't forget that cables also play an important role when it comes to charging.

How are my sure you are not promoting your franchise?? ...

Anyways, thanks for the information. It really helped. Now I can easily identify a fake BlackBerry charger.

Benart:


I think it also shortens the battery life gradually due to the high current the battery takes in

So i recommended every average android users should use a charger with an output less than 1.5A.

Actually in these days 1.5A charger is not even fast enough for the phones that are being released. I remember my LG G3 from 2014 had 1.8A. These days 2.0A seems to be the standard for most phones. Like I said earlier, even if u use a 2.4A charger, ur phone will only draw the amount of current it need, so if ur phone requires 1.5A it will only draw 1.5A.
