Cave man to a city man
EcoFlow is the future

Worth every penny. This solar panel has changed the way I use my EcoFlow max. amazing working art. It even gives me 370 watt in day cloudy day. My generator is always 95-100 topped up. During the day. Just need a little bit of light and they power up. Highly recommend. I dont get paid for this survey and not sponsored. My personal experience. They deserve 5 star. I ordered my 2nd 400 watt panel.

Excellent Solar Panel

Excellent Solar Panel, very good power output... when I tested, I was getting about 350 watts out of each panel, all without even trying hard to get the angle right. Would definitely recommend.

3 x 400W panels outside 24x7 for 125 days straight

We have had 3 of the 400W solar panels outside for 125 days straight, rain, snow, hail, high winds, and no issues. They actually can stand up to sustained use in weather! I've had them flat on the ground and now on the side of a small rise. Running them in serial. I've gotten up to 960w, yesterday I got 940w late morning. For 2 months they powered our seedling far in the water shed (pictured to the right in the photo) . Lately they power up all our battery recharging operations - our water filtration and our freeze drier.

Good buy

Ordered it as soon as it became in stock again. Took a while as it shipped from Hong Kong. Packaging was damaged but luckily the panels were not. The panels are heavier than I thought they would be. Works very well to recharge a standard delta unit - generating max of 200w by lying flat in morning sunlight. Took about 1 hour to go from 86% to 100%.
