220W POWER RATING: One of the most powerful, portable solar power options on the market today, with up to 8.8 amps an hour on sunny days. – VERY LIGHT WEIGHT: Weighing only 13.6lbs it’s so easy to setup and pack up compared to traditional folding panels that can weigh three or four times as much. And when it’s packed away, it is the size of a laptop, leaving more storage for other items you may want to bring on the adventure.

EXTREME EFFICIENCY: It is rarely sunny all day, but the Off Grid Trek blanket’s solar cells are able to harness maximum power even on cloudy or overcast days. The solar panel efficiency is up to 24.1%, while most of the similar products on the market are 15% or lower.  We only use the best Sunpower Gen 3 Maxeon solar cells.

CHARGE YOUR MOBILE DEVICES DIRECTLY: Connect your devices  to the 2 USB, 1 USB-C or DC ports for high-speed, safe charging of mobile devices on the back of the solar blanket.

AUTOMATICALLY BUILT-IN USB IC: Most folding solar panels with a USB connector cannot charge some types of mobile phones due to not having an automatically recognized USB IC. The special IC in the Off Grid Trek blanket makes the charging current as powerful as possible so the charging rate is quicker, where other kinds of folding solar panels only consume some of the output current, making the charging time much longer.

ENVIRONMENTALLY FRIENDLY: Extend battery life by maintaining correct charge levels. Save the environment and your wallet!

The Off Grid Trek Solar Blanket will instantly connect to our optional Solar Regulator via the included, industry-standard Anderson connection so there’s no need for complicated wiring or costly modifications to your existing 12v system.

ETFE Surface: Enhances the Solar Blankets performance and life. Imported from Japan, the EFTE has a better transparency than the normal PET which increases the Solar Blankets Power Output in the same light conditions. The ETFE also increases the life of the solar blanket to more than 10 years.


  • Internal operating temperature for our Solar Blankets is -35C to +65C and for cables -45C to +70C, warranty does not cover use outside of the temperatures should damage occur.

A must have for Preppers

Bought these for quality reviews and portability. Many benefits over Powerfilm and hundreds cheaper

Thank you for the review :)

Excellent portable solar array

When I bought an E-CELLS e-mountain bike I needed a way to charge the bike's two batteries when hunting or camping. The Off Grid Trek 220 watt blanket was the best array of this kind I could find anywhere. It charges my "solar generator LFP battery which in turn charges my bike batteries. No worries about bringing gas to run a small generator. The sun and the O.G. TREK blanket are my power source. Clean, efficient and great for home power outages as well.

Happy to hear that it is working well for you :)


I wish every company was run with such great customer service! Rene was extremely helpful and attentive. I would highly recommend off grid trek to anyone looking for high quality solar and customer service.

Thank you for the review :)

Solar panels, like most aftermarket components, have a general correlation between quality and price. This solar blanket is not one of the exceptions. Pricewise, it’s comparable to the RedArc blankets, but those aren’t currently available in North America. Yes, there are cheaper panels on the market; but if you want assurance that your panels will produce the most energy in the widest range of conditions, this blanket is the best way to go. The quality, mil-spec components and testing Rene used/uses for designing and making these blankets gives them the best chance of not failing exactly when you need it. Customer service is excellent, the owner (when he’s not exploring off the grid himself) is readily available for questions and quickly returns emails and phone calls.

Thank you for the review much appreciated and that reminds me that I need a bit of mountain time exploring soon :)
