If you are worried about keeping your phone charged while having fun under the sun this summer, perhaps what you need is the SOLSOL cap. This rather unique cap has built-in solar panels mounted on the bill. So while you are out having fun, the cap will charge your phone at the same time. All you have to do is connect your phone to the cap with a charging cable.
The solar panels on the SOLSOL uses the highest efficiency panels available today with 18% efficiency. Charging speed is about half the speed when compared to charging from a PC or laptop’s USB port. While this may not sound very fast but when you are stuck with a phone with a dead battery, I bet you won’t be complaining.
Other than the solar panels, the SOLSOL cap looks and functions very much like any baseball cap. It is made from 100% cotton material and it is available in 8 different two-tone and solid colors. While you cannot submerge it underwater, the cap is water resistant and can withstand a light drizzle.
The cap does not come with a built-in rechargeable battery which means it cannot store battery power. It is probably not a good idea anyway to mount a charging battery right next to your head. If you need to store power for later use, you can always charge a power bank using the SOLSOL cap. Also, if you need to get out of the sun, you can always leave your cap and your device charging under the sun while you cool off.
