This power bank has a medium capacity of 2600mAh. This approximates to 2.6amp hours of charging. As an iPhone battery only has a capacity of 1420mAh you may think you would get almost two refills, but unfortunately the charge process does not work on a 1:1 ratio. Beware of anyone who tells you it does! You will, however, get one full charge with some left over for a quick top-up.
This brilliant little device is something we are proud of, so unlike other sellers on the market we offer a one year guarantee – and we are so confident of them you can also have a 28 days no quibble return.
