For a more in-depth review of the Blavor Solar Power Bank, check out this article: https://www.powerbankexpert.com/blavo...

Unlike most other power banks, Blavor comes with a solar panel that can be used for charging. Granted, getting a full charge this way will take a lot of time under direct sunlight, but still, it's doable.

Other than that, it's also worth noting that it also comes with Qi wireless charging and a very powerful flashlight. It's rugged and very suitable for outdoor usage. It can also be taken on flights.
