Two caveats though:
- One on the capacity made: my smartphone has a 3100 mAh battery, so I took it knowing full well it would not provide a full charge. A quick calculation gives us an expected capacity still close to 95% or months I reach 80% charge after complete discharge of the external battery having connected the mobile just under the 15% mark. So I get something like 65% loading my smartphone (30% missing).
- Another on the operation of LEDs: indeed, it has a red LED for battery charging and blue mobile device charging. It would have been wise to have an extinction of the red LED or a green in passing at the end of loading, the fact that the LED is lit leaves doubt on the charge status. However no problem when loading a device, the LED turns off when the battery is empty!
I'm still happy with this small external battery I already repaired several times!
I recommend for a device that does not require 3000 mAh for who wants a full load.
If your device needs the 3000 mAh, I recommend taking a battery with a higher capacity.
