Goal Zero Ranger 300 Briefcase

Sale price$1,099.99

More solar (300 Watts!), less weight. Our lightweight panels let you harness more power from the sun while still being easily transportable from place to place. Perfect for a high-use solar power solution.

Convenient, Foldable Design: Four 75-Watt panels, totaling 300 Watts, chained together and connected at the hinge. Easily pack and transport the Ranger 300 from place to place, then store it when not in use.

Add Solar Power, Not Pounds: Designed with a thinner aluminum frame and ETFE polymer instead of glass, the Ranger 300 adds 100 Watts of solar to the Boulder 200 while shedding 3 lbs.

Easy to Use: Featuring an innovative, patent-pending design, the Ranger 300 kickstand automatically folds out as you open the panel, allowing you to easily position the panel in place while solar charging.

Maintain Portability: Built-in handles and magnetized corners make it easier to fold up your panel, pack in the car and go.

The solar panel does not hold a charge - it only produces power when it is exposed to sunlight and connected to a power station or bank.

Optimize solar panel efficiency by positioning them south-facing at a 45-degree angle.

For faster recharging, use multiple solar panels.
