Modern electronic devices have brought the much needed convenience into everyday living, however one of their biggest disadvantages is how quickly their batteries often can die out. Most batteries in modern electric devices only last a few hours before needing to be recharged, this can prove to be difficult during power cuts or when off grid and without a power pack. That’s where the Rockpals SP003 and the Rockpals RP082 foldable solar panels come into play as they allow one to recharge their battery using free solar power that is readily available during the day. The question however any consumer would want to ask is, which of the two products is much better and offers the best value for the money?
