Charging Interest

First camping of the year and here’s what we’ve learnt:

Bike is fine but keeping the phones charged is a real pain. We have a Power Gorilla (Google it) but it only ever seems to help out for a couple of hours. Charging off the bike used to be the solution but newer phones (htc one m7,nexus 6) use energy quicker than bike can supply it. Nexus 6 on common ac charger (guerilla charging in laundry room) forecasts 3 hours to full but only 2 piggy backing off Power Gorilla (also guerilla charging).
