The charge packs contain either a lithium-ion or lithium-polymer battery, depending on the model, in a plastic enclosure. The units have a 5-volt DC USB input for charging the unit, and 1 or 2, 5-volt DC USB or Lightning output connections for charging devices. The “mini” and “stack” units have additional input and output connections so they can be stacked and simultaneously charge from connection to a single power source. All units can charge device(s) while they themselves are being charged.&&&&The units support a range of input amperage, generally 0.4 to 2 amps. The “mini” and “stack” units output 1 amp. The “slate” units have dual outputs. Two of the “slates” output 1 amp through one port and 2.4 amps through the other. The largest “slate” unit has dual 2.4 amp output.&&&&The units come with a USB cable so that one can charge the battery from any standard 5-volt USB port. The units do not come with a wall transformer for direct charging from the mains. The manufacturer recommends using a charger which comes with one of the user’s devices to be charged to charge the charge packs from the mains. The units regulate output voltage to ensure standard 5-volt output is provided to the device being charged via the USB output port.&&
