Battery packs are great for keeping your phone charged on the go, but what do you do when your battery pack runs out of juice? Well, if it was solar powered, then you could just set it in the sun.
Solar battery packs are relatively cheap, and they can keep your phone charged when you’re away from an outlet. They’re great for camping trips, hikes, canoeing, or power-related emergencies. You could even leave one in the back seat of your car, in case you find yourself in the middle of nowhere with an empty tank and a dead cellphone. You can also use them to charge laptops, GoPros, pico projectors, smart watches, and any other device that you’re trying to bring outside.
These power packs can charge your phone between 4 and 8 times when they’re at a full charge. Just keep in mind that most solar battery packs need about a week in the sun to gain a full charge (you can plug them into an outlet if you need to charge them more quickly). But you could realistically use of these to power your phone forever, so long as you don’t spend your entire camping trip draining your phone’s battery on Facetime.

Feelle 24,000mAh Dual USB Solar Battery Pack ($43)
As we mentioned earlier, most solar battery packs take about a week in the sun to get a full charge. They’re fine for a weeklong camping trip, but they won’t take you off the grid, and they won’t power multiple devices for very long. What’s the obvious solution to this problem? C’mon, add more solar panels!
The Feelle is a solar battery pack that has three solar panels instead of one. It can achieve a full charge after about 35 to 40 hours in the sun, which is radically faster than most solar battery packs. Keep in mind that the Feelle has a large capacity of 24,000mAh. You could realistically use this power pack to keep your phone, laptop, and a few other devices perpetually charged, without ever plugging into an outlet.
This power pack comes in a nice leather case, so you can look cool when you’re backpacking in the middle of nowhere. It has two USB-A inputs, but neither of them are Quick Charge compatible. Hopefully you enjoy the outdoors so much that you don’t care how quickly your phone charges.
