300W POWER RATING: One of the most powerful, portable solar power options on the market today, with up to 11.9 amps an hour on sunny days. – VERY LIGHT WEIGHT: Weighing only 13.23lbs 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 24.5%, 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.

Great 300W panel -- two in series even better!

I did a lot of research before settling on Off Grid Trek (OGT) for several solar blankets. I wanted something compact, durable and, most importantly, reliable in that it would work very well when I needed it. So, for me, these blankets are a great value. To charge one of my Anker Solix powerhouses (C1000), I rigged up two of the 300W blankets in series using the OGT cable that made the connections easy as could be, along with one of the OGT 15' extension cords. Highest rated input to my Anker was an amazing 554 watts in great sun but routinely in the 400W-500W range in good sun. Even in varying cloud cover, watts generated were 100-300W. Very satisfied as I got 500 watt-hours into my Solix in about 75 minutes. Rene was great in helping me work through the best solutions to meet my needs. All products were delivered promptly too. I am much better equipped for power outages with this gear.
I also got several of the 30W solar blankets for other family members (mainly as an emergency or off-grid backup for charging small devices like phones).
Highly recommend OGT!

Hi Todd, that is great output for end of March where you are located, thank you for the review.

Much better than advertised.

Love to compact, mobile solar blankets. Everything that was promised and more. Light weight, easy to transport and position and incredibly efficient. A must have for everyone investing in the future.

Hi Ken,

Thank you for the review we appreciate this.

I’m glad I waited for this product to exist

I had the powerfilm (different company/panel) in my Amazon cart for more than 5 years. When I finally got ready to pull the trigger I did some research and found these panels and went with them instead.

The price is still pretty steep for my meager wallet, but after seeing other panels drop to 0% energy production from one measly shadow or cloud I knew these were the right ones for me.

This is my first solar panel purchase ever and god willing I will make enough money to buy and set up everything my family needs. 73

Hi Yohance,
Happy that we could help, we appreciate the review.

Exactly as adverttised

I'll be honest, the 'low light conditions' video attached to this product page won me over. i got EXACTLY what i paid for, no marketing nonsense, no time wasting, good, honest "here are some realistic expectations" and i actually got them.

I used to it charge a Montek 1000 which then charged my R/C car batteries. i made a whole day out of playing with my dumb toy and i not only charged two R/C batteries (80W charge rate a piece) but had more than enough to power my 12V fridge (50W) and charge my phone too.

Oh and i ran all of that with JUST the panel (80x2 batteries = 50W fridge = still less power than the panel made). Granted it was pass-through power because the blanket doesn't have a 12V car charge port but that's besides the point.

I am very happy that i can throw this on the roof of my car so quickly (the 300W blanket in particular is too wide to fit on just the windshield even on full size trucks.), and charge everything i need.

I look forward to helping my neighbors this hurricane season so they don't have to chug gas in their cars JUST to charge their phones.

Hi Brett, Happy that this will allow you to help not only yourself but your neighbours as well when needed, that is Awesome. Thank You for the review!

Have a 220W OGT blanket WANT a 300W version

I really like my 220 watt OGT solar blanket but if the 300 watt version was available then I would have purchased it for few hundred $$ more. I need that extra wattage to charge my BLUETTI AC200 MAX even though, on the "PV" setting it does charge well with the 220 watt version. In short GET THE 300 WATT BLANKET.

Hi Eric, Thank You for the review, it is appreciated!
