Port Solar Charger
Carrying around a backup battery for those times your smartphone goes flat isn’t a bad idea, but what’s going to charge the charger if its batteries run low too? XD Design’s Port Solar Charger remedies this potential catastrophe by pairing it with a built-in solar panel and silicone suction cup, sticking to a window or airplane porthole for fuelling up midday. While the 3.5-inch diameter device packs a battery capacity of only about 800 mAh, i.e. not enough to fully charge most modern day smartphones, it still suits road trips, outdoor adventures, and long flights just fine.
