FreeLoader - 300W SunCharger

The FreeLoader is the next step up from the SunCharger. It packs more power so you can do the things you love longer, while still maintaining lower cost and weight measurements.


Manufactured by Sungzu, the best solar power systems money can buy, this is where multi outlet use begins.


With a FreeLoader system you can run multiple appliances at the same time. If you’re not sure what you’d want it for, think about what you would want in a dorm room or small cabin.


For outdoor power situations, this is perfect for bringing the comforts you need outside: a fan to keep you cool, lighting for ambience or better visibility, or a projector and stereo for your own outdoor theatre. Measured entertainment center time of up to 6 hours.


If you have a boat, pair this with a solar panel for an easily accessible solution to off-shore power. The same concept applies for RVers: this means no more running your truck to get your batteries charged!


Look into our bundle section for the pairing that matches your lifestyle and budget.
