    • Incredible Capacity with Solar Backup
Color: Blue
This 41,000 mAh power bank is an absolute powerhouse. It easily keeps all my devices charged for days on end, making it perfect for long trips or emergencies. The added solar panel is a fantastic bonus for peace of mind when you're off the grid. While solar charging is naturally slower on a capacity this massive, it's a great backup feature to have in a pinch. It is well-built, reliable, and highly recommended for anyone needing serious portable power ... show more

    • High capacity charger in a small package.
Color: Orange
Very high capacity charger. I can't believe they were able to pack that much battery into something that is seemingly pretty small and flat. It could barely fit into my pocket but it's a really impressive device. Very durable packaging. Many ports for connecting. Solar charging works great. Great flashlight.. Charges quickly. I feel like this is a must for every car. Definitely for the home. When the lights go out this thing can charge your phone eight times . ... show more

    • Solar panel adds essentially zero charge
Color: Black
Placed in bright sunlight for nearly an entire afternoon and battery barely increased at all. The panel exists purely for appearance.

    • Great solar charger
Color: Blue
Purchased this in case our power were to ever go out and no longer have access to electricity. I didn’t realize how big it would be (it’s larger than my iPhone 15pro) However that makes it so there’s a larger surface area to charge. My SIL borrowed it and she said it charged her Samsung phone faster than her wall charger. A keeper for sure ... show more
