Please note that the HomePower ONE is designed to be a PORTABLE power station. It keeps your choice of home devices charged and operational for up to 7 days on a single charge (depending on the power required by the individual device and the frequency of your using it). It's compatible with home appliances, electronic communication and medical devices, security systems, and more. You can conveniently take the HomePower ONE to the area where your device is located, and plug your device into the unit. If your devices are located in different areas and you need to power them at the same time, you can either move all the devices to one area or buy multiple HomePower ONE units for more backup power and flexibility.
