We’ve introduced many portable chargers. But apparently a nice charger has been left out. That’s ZAGGsparq 2.0 portable charger by ZAGG.
The portable charger looks like a fat outlet. It measures 3.5 x 3.5 x 1 inches, and weights 54 lbs. In its big paunch there is a 6000mAh rechargeable battery pack in order to ensure your portable devices never power-hungry. The two USB ports allow you to simultaneously charge two USB devices such as smartphone, iPhone, iPad, and etc. Apart from that, 4-light indicator can tell you the battery status.
