This year, Tylt is betting big on external battery packs, bringing several new lines to the market. They range in capacity, size, and shape, but share a general aesthetic. Each has at least one distinguishing factor that sets it apart from the many other batteries on the market.
Energi 5K+ Battery Pack ($90) is a slim pack, housing a 5200mAh cell. It has both Lightning and micro-USB cables built-in, as well as a USB output port. Each charges at 1-Amp speeds.
Physically smaller, Energi 3K Travel Charger (~$60) has fold-up wall prongs, and a captured Lightning cable, in addition to a standard 3000mAh cell.
Energi 2K Travel Charger (~$30) drops the cable of the larger edition, substituting in a USB port. It has a 2200mAh cell.
