Without the use of fuel, the ultracompact Extreme 350 Power Pack stores 350-watts to run appliances and other devices for hours, and at only 26 lbs., it's relatively simple to transport.

For use as a primary power source, the power pack can be charged via wall outlet, solar panel (not included) or with the car adapter (not included). The unit will hold a charge for three to four months, so it's not always necessary to recharge after light-use outings.
