Do you know what is the purpose to which it was put, such as power consumption, and stand by time. Multiply these two along and you can arrive at the AH. Add a 10% to be on safe side. the voltage is same as what you had used. If a 12V operated stereo is taking 200mA and can be used with power pack for say 8 hours, then its Ah is 1.6, and voltage is 12V. So I will use a 12V 2Ah battery pack for getting the desired standby time. see if the link gives any clue. Look for a matching photograph of the item and check out whether it has same dimensions, like height, width and thickness.

The voltage is obviously 5V, but it may not be just a battery pack as I had thought.

Simply to say, mAh is the capacity a power bank owns. For example, a 10400mAh power bank has twice the power than a 5600mAh one. I don't know how much yours has. I personally has a RavPower 14000mAh battery charger and it's a juicy one which charges my phone 5 and more times.

There is no capacity specification marked on the box . But you can test it to get know what capacity it is by charging your mobiles .

Firstly you can charge the power bank full , then you can use the power bank to charge your phone . Then let us know how many times it can charge your phone full ?

For example , your phone battery is 1450mA and the power bank could you charge your phone 4 times . As usual the power bank's exchange rate is about 85% .

Then we can account it by 1450 x 4 /85% =6823 , And when power bank charge /discharging , itself has some power consumption . So the capacity is around 7000mA~8000mA .

Hope it helpful to you

You can charge your mobile ,according the mobile battery capacity and the charge times you can calculate the actual capacity of your power bank.

it was on the box but i threw it some time back and i can't remember it now.. anybody with this power bank help me out maybe?
