Power is everything when traveling, and a lot of times our chargers can take up tons of space. The inCharge is the size of a small keychain and has six different charging input and output combinations to provide power to your phone, headphones, e-reader, smartwatch, and more. For quick reference, the inCharge has these specific ports: an input USB-C, an output USB-C, a USB-A, and an output lightning plus micro USB.
