9callmark Posted June 13, 2016 Share Posted June 13, 2016 Found this online.It is interesting to combine a battery charger and lightweight outdoor powerbank. I have several rechargeable li-ion batteries, so I think it can help to reduce my backpack weight. It is said can also connect with a solar panel to store solar power into the batteries. This sounds cool. Link to comment Share on other sites More sharing options...
