Nature's Generator Elite Power Pod can be used independently or in conjunction with the Nature's Generator. It comes with an internal 100Ah Sealed Lead Acid battery that can be recharged through the solar panel input on the front of the unit. On the front of the unit we also include an LED light fuel gauge to let you know the units level of charge as well as a 12V DC outlet. Although the Nature's Generator Power Pod doesn't come included with our custom heavy duty cart (when not bundled with Nature's Generator) you can purchase that separately, creating ease of use and transportation from one spot to the next. The Nature's Generator Elite Power Pod also includes a compartment on the top section of the product. The fuse connector for expansion purposes is stored here. You can also store any other items inside the compartment that you may want to keep handy with your unit.
