If you’re one who finds yourself frequently hiking, camping, or just generally away from an outlet, Bushnell’s Bear Grylls Solar Wrap ($89) is a great option for charging your electronic devices. This Lithium Ion battery solar charger connects via USB, and can hold a 4-hour wall charge, or a 10-hour solar charge. When rolled up, its compact size of 4.3”x1.25” is small enough to fit in your pocket, and its deployed size of 18”x1.25” is ideal for connecting to the front of your backpack. Better yet, at only 3.1 pounds, you’ll barely notice the addition either way.

Fear not if it happens to be an incredibly overcast day. The Solar Wrap has fully multicoated optics and razor-sharp BaK-4 prisms so it can almost always find enough sun. And should you happen to take a tumble down a hill, only to land in a stream, its rugged and waterproof design means you wouldn’t find yourself up a creek in another sort of way.

So grab that friend who says they’ll never go outside with you because they can’t live without their technology, because now you can enjoy the feeling of being off the grid without actually having to do it.
