The most powerful wearable is the EcoFlow Power Hat
Charge your gadgets from your head with this wearable solar hat.

When I think of solar panels in hats, I think of a baseball cap with a fan in the brim and a couple of small PVs hot glued to the top.
The EcoFlow Power Hat is not that at all. This wide-brimmed hat has solar panels incorporated into the brim all the way around, so it can capture energy from all angles.
Weighing in at just 370 grams, the hat is lightweight and flexible enough to be taken anywhere. It's rated at IP65 and features both USB-C and USB-A outputs, so you can use it to charge two devices simultaneously.
