How many times can the power bank charge my phone/devices?

The time it takes to charge a device with a power bank is dependent on a number of factors. Firstly and most important is the output of the Power Bank, most are 1A output. Only larger capacity power banks (5000mAh +) will have a 2A or 2.1A output. A second important factor is the resistance of the cable used. Some cables only have a 1A capacity capability.The same calculation as above can be used to calculate how long the power bank will take to charge a device. The example below assumes there is 0% power left in device battery.
Powerbank output: 1A
Phone battery: 1500mAh
Calculation: 1500mAh / 800mAh = 1.875 hours
(Why 800mA? An estimate of 20% power is consumed during the charging/ discharging process)

Which adapters are right for use the devices?

If you are unsure which adapters or cables to use with a power bank, the easiest solution is to use the USB cable that came with your device. You can study the adapter on that cable to identify which adapter to use by simply comparing them.We supply cables with multi adapters so that our power banks can be used with many brands or types of devices. The above 3 in 1 cable covers over 98% of new cell phones.

How many phones will a Power Bank be able to charge?

The simple answer is the Economy Class Power Banks can roughly fully charge one phone.
Business Class Power Bank may be able to charge a couple of phones depending its capacity.
The iPhone capacity ranges about 1450 mAh, Galaxy phones range from 1650 mAh to 2600 mAh. The iPad ranges 6600 mAh to 11620 mAh.

How do I know the power bank is true capacity?

Fake capacity power banks are a dime a dozen right now in China. We have specialised testing equipment that allows us to place a load on the power bank or battery we are testing and then measure the output duration of the battery. This gives us the true capacity of a battery or power bank. Feel free to pop into our office to see this equipment and test any of our power banks.
