215W Solar Blanket | Waterproof | 23.5% Efficiency | 13.6 lbs | No US Sales Tax
Portable Solar Power Built for Real-World Conditions
Most solar panels are tested under perfect laboratory conditions.
Real life is different.
Wildfire smoke. Cloud cover. Rain. Snow. Morning fog. Haze. Low winter sun. Partial shade. Dust, mud, and changing weather conditions.
The Off Grid Trek 215W Solar Blanket was designed for those real-world conditions.
Built using genuine SunPower solar cells with a 23.5% efficiency rating, this waterproof solar blanket delivers dependable charging power for power stations, batteries, Starlink, communications equipment, refrigeration, and essential electronics.
Its lower-voltage design also makes it compatible with many smaller portable power stations that cannot accept the higher input voltages of larger solar panels, providing greater flexibility when building a portable power system.
Compact, durable, and easy to deploy, it provides reliable portable power wherever your adventures take you.

Waterproof and Built for the Outdoors
Weather doesn't always cooperate.
Rain, snow, mud, dust, and harsh conditions are part of every adventure.
Unlike many portable solar panels, the Off Grid Trek 215W Solar Blanket features a fully waterproof design built for real-world outdoor use.
Whether you're overlanding, camping, living off-grid, fishing, hunting, traveling in your RV, or preparing for emergencies, 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 bulky and difficult to transport.
The Off Grid Trek 215W Solar Blanket folds into a compact package while delivering substantial charging capability for:
• Portable Power Stations
• LiFePO4 & AGM Batteries
• Starlink
• Portable Refrigeration
• Ham Radio Equipment
• Overlanding Vehicle Batteries
• Trailer & Camper Batteries
• RV House Batteries
• Emergency Communications
• Cameras & Electronics
Its 22.3V open-circuit voltage makes it compatible with many smaller power stations that cannot safely accept higher-voltage solar panels, making it an excellent choice for customers looking for maximum compatibility.
For overlanders and remote travelers, the ability to recharge vehicle batteries, trailer batteries, and critical equipment without relying on shore power provides true energy independence.
Designed for Real-World Solar Production
Cloud cover, smoke, haze, and low sun angles can significantly impact solar production.
Built with genuine SunPower solar cells, the Off Grid Trek 215W Solar Blanket is designed to maximize energy harvest throughout the day, helping generate more usable power when conditions aren't ideal.
When every watt matters, efficiency matters.
Compact, Durable and Easy to Deploy
The best solar panel is the one you actually bring with you.
The Off Grid Trek 215W Solar Blanket was designed to be easy to transport, quick to deploy, and simple to store.
Fold it.
Pack it.
Deploy it in seconds.
Whether you're setting up camp, charging batteries at a remote work site, maintaining communications equipment, or powering your next adventure, you'll appreciate having serious charging capability without the bulk of traditional solar panels.

Customer Reviews
Excellent service and excellent products.
Thank you for the review :)
Finally had a chance to test the 215Watt solar blanket to charge a goal zero yeti400 and It works like a charm. Charging from 60 to 100% takes less time than via wall outlet.
Haven't run the yeti400 to lower than 40% to see if that's calculates to take longer but I trust the blanket is up for that too. In overcast the blanket will putout approx 8watts into the Yeti, even when only 1 patch is in full sunlight and the rest in shadow. ( took no watt value in that situ)
approx 15watts from 5 patches in sunlight/shadow from balcony railing
approx 30watts from 9 patches in sunlight/shadow from balcony railing
approx 58watts from all 15 patches in sunlight/shadow from balcony railing
I use it during the evening to run a aquarium pump to run a small gold sluice setup. I can see this setup with any other brand of Solar power generator in the field with gold prospectors.
This product delivers and Rene's service is outstanding. Thank's Off Grid Trek
Thank you for the review, I am happy we could help you :)
My experience with Rene and OGT was a great one. All products are sturdy and of quality materials. I use the 215 w Solar Blanket to charge the Inergy Apex, running a Snomaster fridge; and on a sunny day with small clouds and the fridge pulling current, there was still 175 w left over to charge the Apex itself.
Happy it is working well for you, thank you for the review :)
“I purchased the 215 watt solar blanket as a charging option for the Inergy Apex. I am a CPAP user and I wanted something mobile (no large solar panels) and something that would be easy to hookup.
I called Off Grid Trek and spoke to the owner of the company. All questions I had were answered to my satisfaction. I will consider a smaller 28.5 watt solar blanket for charging a cell phone or other electronics while outdoors.”
Happy that we could find a solution for you :)
“I have only used this product once to charge my Inergy Apex. Hookup and deployment of the solar blanket was easy. If you are looking for charging and travel flexibility with the Apex, this is it.”
Thank you for the review :)
