Ideal for putting multiple charges into phones and small devices like cameras or GPS units, the black Goal Zero Flip 24 6700mAh Portable Power Station is a stylish power solution for anyone who needs to keep their gear going when they're out or off the grid for a long weekend. A flip-out USB plug charges the 3.6V, 6700mAh capacity Li-Ion NMC (nickel manganese cobalt oxide) battery from standard USB computer ports or wall plug adapters or plugged directly into many Goal Zero solar panels like the Nomad 5 or 7 Plus to get its charge. The Flip has a single standard USB output port that accepts your device's charging cord and outputs 5VDC (up to 2.1A, 10.5W max). Designed to be highly portable it measures just 3.7" long and weighs a mere 4.6 ounces.
