EcoFlow sent their 160W Solar Panel to the field lab as a companion to the RIVER 2 we recently reviewed. The 160-watt solar panel is a 4x40-watt portable folding solar charger for portable PowerBanks. It comes in a nice cloth carrying case that doubles as a stand, and weighs in at 15.4 lbs. With 160W of maximum output, we decided to try out taking the remote observatory off-grid to see what we could accomplish.
