300W Solar Blanket | Waterproof | 24.5% Efficiency | Only 9.9 lbs | No US Sales Tax

Dependable Portable Solar Power When Conditions Aren't Perfect

Most solar panels are tested under perfect laboratory conditions.

Real life is different.

Wildfire smoke. Cloud cover. Rain. Snow. Morning fog. Haze. Short winter days. Low sun angles. Partial shade from trees. Dust, mud, and constantly changing weather conditions.

When you're overlanding hundreds of miles from the nearest town, living off-grid, preparing for emergencies, or depending on solar power to keep essential equipment running, perfect conditions are rarely guaranteed.

The Off Grid Trek 300W Solar Blanket was built for the real world.

Featuring genuine SunPower Gen 3 Maxeon solar cells with a 24.5% efficiency rating, waterproof construction, and a compact folding design weighing only 9.9 lbs, it delivers dependable charging power for power stations, batteries, Starlink systems, communications equipment, refrigeration, emergency gear, and more.

Unlike bulky rigid panels, the 300W Solar Blanket folds to approximately the size of a laptop, making it easy to store, transport, and deploy wherever power is needed.

Waterproof and Built for Real Outdoor Use

Weather doesn't stop adventures.

Rainstorms roll in unexpectedly. Snow falls overnight. Mud, dust, and harsh environments are part of life outdoors.

Unlike many portable solar panels that need to be packed away at the first sign of bad weather, the Off Grid Trek 300W Solar Blanket features a fully waterproof design built for real-world use.

Whether you're camping in the mountains, traveling remote backroads, living off-grid, hunting, fishing, responding to emergencies, or maintaining communications during power outages, this solar blanket is designed to keep producing power when conditions become challenging.

Maximum Power Without the Bulk

Traditional solar panels are effective but often difficult to transport and store.

The Off Grid Trek 300W Solar Blanket provides up to 300 watts of charging capability while folding into a compact package measuring only 290 x 310 x 85 mm.

When folded, it takes up minimal cargo space. When deployed, it provides serious charging power for:

• Portable Power Stations

• LiFePO4 Battery Systems

• Starlink

• Ham Radio Equipment

• Portable Refrigeration

• Emergency Communications

• Cameras & Electronics

• Remote Monitoring Equipment

• Mobile Devices

• Overlanding Vehicle Batteries

• Trailer Batteries

• Camper Batteries

• Remote Basecamp Power Systems

For overlanders and remote travelers, the ability to recharge vehicle-mounted auxiliary batteries, trailer batteries, and camp power systems can mean the difference between extending your adventure and heading home early.

Designed for Real-World Solar Production

The difference between a solar panel on paper and a solar panel in the field is performance when conditions aren't ideal.

Cloud cover, smoke, haze, and low sun angles can dramatically reduce output from many solar panels.

Built with genuine SunPower Gen 3 Maxeon solar cells and a 24.5% efficiency rating, the Off Grid Trek 300W Solar Blanket is designed to maximize energy harvest throughout the day, helping you generate more usable power when you need it most.

Because when you're depending on solar power, every watt matters.

Compact, Lightweight and Easy to Deploy

At only 9.9 lbs (4.5 kg), the Off Grid Trek 300W Solar Blanket delivers substantial charging capability without the weight and bulk associated with traditional solar systems.

Fold it.

Store it.

Deploy it in seconds.

Whether you're operating from a vehicle, RV, cabin, basecamp, or emergency location, you'll appreciate the portability and simplicity of a compact solar blanket designed for life on the move.
