PEARL Revolt 28-watt foldable solar panel review: Perfect for bike trips, hiking and co

Because unlike pointless solar products such as power banks with solar cells (please don’t buy them!), where the panel size is not nearly enough to charge the product in a meaningful way, the Revolt folding panel with its four modules is very capable of supplying smartphones, power banks and similar devices with power throughout the (sunny) day. We charged both our smartphone and power bank during the trip, so we still had enough energy in the evening. Only on the rainy Saturday did we leave the panel completely in our bag.

However, if you only cover one of the four modules completely, the charging current drops very sharply. And in our test to charge two devices at the same time, the display never showed more than 2.4 A even with good sun and orientation. Apparently, the current is not displayed for both outputs at the same time, because both devices were charged quite quickly. On the other hand, the charging process stopped and restarted every now and then even in good sun, so charging two devices at the same time doesn’t appear to be very sophisticated.
