This is one product you almost hope you don’t need. The iWerkz Solar Charger can keep your mobile devices going as long as you need using the power of the sun. It folds up to be nice and portable and clocks in at just over a pound. It’s something you should always have with you, or keep in the car.

Just imagine you’re stuck in the middle of nowhere and your car battery is dead. You call for help but can’t reach anyone. You need to stay in communication. You’re fine until your cell’s battery runs out but what then? Out there the cell service may be spotty and that means the battery drains faster. At the first hint of trouble, set up this solar charger and let it gather all the energy it needs from the sun. With 2 amps of power output, it will get your phone working again quickly and keep it working until you get rescued.

This is a great thing for campers to bring too because if you get lost, you have no access to other power. You may be relying on your phone for survival at that point. Setting this up at the campsite means you’ll have power as long as you need it.

When you really think about it, you should be looking at getting several of these little chargers. Put one in each car, keep one in the emergency kit at the house, one in a travel kit, keep one with your camping or hiking supplies. This is the sort of thing you should have when you need it. You’ll be really glad you did.
