# Does using a higher amp micro usb charger destroy the device battery?

My spare jiofi device came with a 1A micro usb charger, and my phone uses a 2A micro usb charger.

I want to occasionally charge this jiofi device to not let the battery drain down completely.

Is it safe to use the 2A charger on the jiofi device, by using a higher amp charger will it affect the battery life?

This is the same question I had posted few days back. Some has copied it and re-posted it again. What is going on here?

It reduces the battery life

Ideally charging current should be 1/10th of battery capacity for maximum battery life

Since 1500mah battery would be there. Better not to use 2amp charge. Use 1amp or less

You can use a 10A charger if you want. It is the device that regulates how fast the bettery gets charged. Now a 5000mah battery charging from a 5v charger can charge it at 1C which means the battery is 3.7volts and 1A which equates to 3.7 watts.. So it will charge the battery to 100% or so in about 1.5 hours.. New phones charge faster than 1C but they regulate it so only like 20-80% of the charge is done faster while the rest is done slower..

Many terminologies here.. 1C means charge capacity v/s speed of charging which is in Amps.. You need special handling to charge faster.. Also batteries are not 5v but 3.7 volts..

The main problem with charging is, you can charge a battery upto 4.2volts without problems and get 90% capacity.. 4.3volts to get 95% and 4.4 volts to get 100% but at 4.4volts the battery can develop problems.. You can also overcharge the battery to get 110-120% capacity.. The higher voltage you charge the shorter its life.. Most everything will only charge a battery to 90-95% or even less.. power banks only do 80-85% because they want you to reuse it like 500 times..

1C means unit of charge bro.
