Exogear’s Exovolt Plus is a stackable battery pack, meaning you can pile on as many together and create a battery powerful enough to recharge even the biggest power guzzling gadgets.
The Exovolt Plus consists of two parts (each sold separately): a main unit and a sub unit. The main unit is the half with the USB port, charging LEDs and power button.
Each main unit has a capacity of 5,200mAh and can be stacked with what appears to be unlimited sub units (capacity appears to be 5,200mAh as well) to create an “unlimited expandable battery capacity.”
The Exovolt Plus will be available ‘soon’ and it will cost $89.95 for the main unit and and $49.95 for each sub unit.
