JAQ: Off-grid Charger for Smartphones

Your smartphone may be powerful, but it does not have an unlimited battery life. If you plan to spend a lot of time outdoors, you are going to need a decent portable battery charger. The JAQ is not your average charger though. It generates energy from water and salt contained in its slim power card. You can carry multiple cards in your bag to always have power on the go.

Once you have charged your phone, you can remove the power card and throw it away with peace of mind (it is recyclable). Each card has 2400 mAh capacity. You charge Android, iOS, and Windows smartphones and tablets with this. The product will debut later this year.
