Can I charge my phone with a PowerBank with less milliamp hours (mAH) capacity?

Question

Batteries

Are Powerbank Drobak KL-5071 1200 mAH and LG Optimus phone compatible with 1500 mAH battery? And what can happen if such a power bank is used for a long time to charge this phone?

Answer 1

Ahem... And what should happen? Nothing will happen, the same thing as disconnecting from the network by 70-80% of the charge.

Answer 2

As soon as the voltage on the elements of the power bank drops below the level morally approved by the controller, it will turn off the voltage supply to the converter.
If the power bank is a collective farm, without overdischarge protection, then the controller in the phone will interrupt charging.
In any case, everything will be ok.
