Hi, I was evaluating if I should get more batteries or an AC powerbank, I ended with the later. It charges 2 MP batteries from 30% to 100% and there is still some power remaining. So I think it is quite nice https://lifepowr.co/
Additionally, with the solar panel it is supposed to refuel in 5 hours at full sun, so quite a nice combo for trekking etc
