Click to Download PDF Specification Sheet

The PowerBank™ is a battery powered AC generator and Uninterruptible Power Supply (UPS) that stores electricity for use when and where power from the grid is unavailable: remote, off-grid, emergency and black-out scenarios.

As a reliable primary or back-up power supply, the PowerBankTM is safe for indoor use, is non-toxic and does not require ventilation or cooling.

Fully charged, the PowerBank™ 5.4 delivers 5,400 Watt hours (5.4 kWh), a sufficient reserve to operate computers, appliances, AV equipment, power tools, fans, electric blankets and medical equipment for hours or days at a time (see run-time chart below).

How the PowerBank™ Works

UPS Mode (Uninterruptible Power Supply)

  • Plug a standard extension cord into the PowerBank™ “AC Input” and into a standard AC outlet (wall socket)
  • Plug electronic devices and equipment into one of the PowerBank™ AC or USB DC power outlets
  • Turn the PowerBank™ inverter “ON” using the Controller Module (refer to manual as needed)
  • AC Power will now be available from the PowerBank™ AC outlet
    • The AC grid automatically charges the PowerBank™ whenever the batteries need recharging
    • During a grid failure, the PowerBank™ automatically switches to UPS mode enabling uninterrupted
      (continual) and reliable equipment operation

Remote AC Power

  • Utilize the PowerBank™ wherever and whenever reliable uninterrupted power is needed
  • Turn the PowerBank™ inverter “ON” using the Controller Module
  • Plug electronic devices and equipment into the PowerBank™ AC or USB DC power outlets
  • Power is now available to run your electronic devices and equipment for hours or days at a time


  • When battery power is low or whenever time permits, plug the PowerBank™ into the wall, generator or solar/wind charger to recharge. Charging can be done as frequently as desired without harm to the system or the PHI 2.7 batteries.

The power required to run equipment in everyday situations varies with the electrical device. Appliances such as microwaves, irons, toaster ovens, and hairdryers require high current for short periods of time. Appliances such as televisions, computers, fans, and refrigerators use low current for extended periods
of time.

For example, if all of the following devices are used once a day, the total usage will be less than 1,500 watt hours.
