Size: 300W
To me, this is a magnificent product when set up I’m always putting out between 37 and 39 volts is producing between five and 7 Amp. And that’s depending on the sun angle and conditions in the sky. I set it up once and it started producing one to 2 A before the sun was even completely just from the light of the bright day. I love this product. It’s a 48 volt 40 volt open current which I have to have to charge my 48 V E bike with a boost charge controller. It’s not a 12 V 18 V it’s not designed unless you have a step down charge controller the steps it down to that voltage. ... show more

    • 1.5 star. 8 reasonable charges.
Size: 300W
Came out of the box maxing out at 252W. I have strong sun in Orange County Ca. Laying completely flat gets the most wattage. I only received about 8 charges at starting at 250w and gradually declining to 150w. Then was only in the 60w range. So I wiped it off and it went up to 125w for an hour then straight down to 60w. Now even when clean and good strong sun ( that is only Way I use it) max watts are 64. So I you want to waste $245. For 8 reasonable charges. Buy it. This product is a rip off. 1.5 stars ... show more

    • Light weight for the size.
Size: 300W
I liked the weight and that it carries easily. Do not like the supports that are supposed to hold it up. If anyone sneezes with in 25 yards of it. The panels fall over and it's hard to get back up by your self.

    • Never worked
Size: 300W
Unfortunately, I ordered this while it was still cloudy and rainy, so I didn't get to use it until after the return window had closed. It doesn't work. I have an identical panel from this seller that does work so I didn't think there would be a problem until it was too late. I emailed the seller and never heard back. Don't buy this unless you can test it right away. The one that does work has NEVER pulled anything close to 300W. The most it has done is 160W. I've been terribly ripped off by this company. Edit: I have still not heard back from them two months later. ... show more

Works very well with ecoflow power station . Took it camping and was able to charge from 85%to 100% in 50 minutes full sun . Just the other day I put it outside to charge and was pulling about 230w . The downside is moving the panels around if you are under trees in the forest. Other than that it works, would recommend it ... show more

    • It's the form factor
Size: 300W
I am new to solar, bought this to go with a generator. Shipped outside of the US so had to pay for the weight. It has worked well so far. I recently compared it with a traditional solar panel which is huge and quite heavy. For the size it is very effective and efficient.
