BakUpBox Video

Unlimited Power Ltd. has issued utility and design patents protecting the BakUpBox in the US and Internationally. This video gives you introduction to the BakUpBox.

What it does

Combat Ready Power

The BakUpBox MilSpec unit is designed to charge quickly and provide up to 1000Wh of power for active missions. The MilSpec unit weighs less than the current weapons and ammo load todays troops carry. At less than 30 seconds it has the quickest set up time of any military solar product available.

Disaster Preparedness

In a disaster, the BakUpBox can provide emergency power to keep your electronics running for days. When the unit runs out of power, just set it in a window or outside and it will recharge from solar in hours, not days like some other units.

Power on the Go

You can use the BakUpBox  anywhere and at anytime, day or night! The stored solar energy can be used for camping, in your RV, Tailgating or for work around your house.  The uses are "unlimited!"
