Power your smartphone on the go with this Tzumi Pocketjuice 3488BB-3 portable charger, which features a 7800 mAh built-in battery and a 2 USB ports for charging. The rubberized coating offers easy carrying and a stylish design.
This product has worked well for me for recharging my phone. The battery life advertised seems to be accurate. It is a bit bulky. If I were to purchase one again, I would look for a smaller version.
