The required solar charging time is long.
Solar panel is not always reliable


Power outages are an ongoing issue across the country, with the average U.S. electricity customer experiencing eight hours of power interruptions in 2020. With so many relying on internet access for work, school and personal activities, a disruption of even a half hour or so can be a problem.

Having a backup power source can help keep your devices up and running at all times, even when you don’t have power at home. But a smaller, more portable power source means you can take it on the go with you. Stuck at the airport with no way to charge your phone? No problem, as long as you have your handy power bank with you.

A solar power bank gathers energy from the sun to power your devices. As long as you have access to direct sunlight and some time, you can charge your electronics without using electricity at all. That makes power banks a great option if you’re looking for a sustainable way to charge your devices.

For best results, your solar power bank will need to have access to direct sunlight for the time necessary to charge them. You can charge them through a window, but they won’t be as efficient as those charged in direct sunlight.

If you’re using your power bank while hiking, some allow a carabiner to be attached. You can then hang it from your backpack to expose it to the sun while you walk. If you’re camping, you could hang your power bank on your tent where the sun is hitting it.

You might not always have access to sunlight, though. For those times, you’ll need to be able to charge your power bank using electricity. Your power bank should come with an adapter that provides a backup charging method for when solar power isn’t an option.
