How Much Can 2200mah Charge. The wall charger will charge the power bank at a faster rate than the computer. The timer takes longer because these can only be charged at much lower current rate of 01C or 110C mAhr10 charging time in hours of their mAh capacity value.
Iusuallycharge at 12C at home though since I have the time and I just think it is safer. Generally speaking a good rule of thumb is to divide the mAh of 20000mAh power bank by the mAh of your device battery. However it should not essentially be double depending on the electronic equipment within and quality age of the battery.
But only go above 1C if the pack specifically says you can.
How many times 30000 mAh battery capacity of your smartphone. MAh is how many milliamperes a battery can deliver in an hour. Generally you can charge up to 1C so youd be safe charging at 22A. Usually between 30 mA to 100 mA depending on the 9V battery capacity in mAh.
