The ALLPOWERS 100W foldable solar panel is delivered in a cardboard box including various adapters for connecting to power stations. There are also 2 USB outputs for directly charging small devices with USB voltage. The idea of folding small solar panels together is interesting. However, the overall structure then has no stability and must be “stretched” accordingly in order to achieve full performance. Hanging from a vertical surface or laying on the floor will not produce the maximum possible performance. On the other hand: Better little than nothing... so you're happy to at least be able to provide your cell phone with a backup charge. On a bike trip, the weight of just over 2kg doesn't play a dramatic role, it only takes 2 minutes to set it up during breaks and connect it... The charging current of just over 2A isn't much, but every little bit can help... I always have it I also attached a small power bank to the second port... No matter how the panel was (in the sun), there was always enough power... I'm satisfied, the panel is good for my purposes. Only the price is a bit steep and the purchase needs to be carefully considered.
