This is my second time order one 400W solar panel for power station use. GreenMagic 400W is very nice product after i checked out, i want put more details below: The package has one 400W solar panel/around 10fts cable/multi-connectors/parallel kits for MC4 connectors/Manual. I had plug it in my power station from 10:00am-5:00pm, Charging performance is very good.The highest charging power can be around 330W and it dropped some due to summer hot weather i guess. Besides the charging performance, it also has some nice features what i noticed such as obviously lighter than my first 400W solar panel,it has multi connectors for match many kinds charging ports needs, came with parallel MC4 connectors for 800W power use(2 * 400W), Finally the price is very good compare with quality of others brand solar panels. Expecting GreenMagic can launch more nice products soon.

I bought two of 400W solar panels. It took only two days to delivered (by FedEx). It came with one big box and two small boxes inside. Each box has 1*400W solar panels, multi-connectors kit, parallel kit, 10ft charging cable with MC4 connector and the manual. I charged my battery for couple hours by these two 400W panels through parallel kits. The charging power range 480W-580w. I believe it might go higher under in nice sunshine weather! Besides charging power, I was surprised by the quality. The flexible panel is pretty durable and weight is obviously lighter compare to my old solar panels. Easy to carry on and it fits in my SUV trunk. Finally I recommend GreenMagic 400W. It is a great product with good features!

I liked that it was easy to setup but it lacked a stability pole. This panel is almost identical to another panel I own that included a 300 CM collapsible pole to stabilize the panels. (EENOUR looks the same panel and I own that one and it came with the pole) if this panel came with the pole it would garner a higher rating. I really liked the connector, it included all the combinations you might need to connect to your charge controller or solar charger. I was able to get 298-305 watts in direct sunlight. Not bad, but less than the rated. Open circuit woltage was 43v

Ordered mine about 5 months ago. I got 2 and returned 1 — I don’t remember my reasoning — but they did not give me a hard time about it. I will most likely order my second one again soon. This one is holding up pretty well. I get about 280 to 320 on them, and most start going down or looking pretty bad after a couple of months. This one is holding up great and still looks brand new. At the same time, I take care of my stuff. If you leave it outside for days, I have no idea how well it will hold up. Mine gets put away when not in use.

I now have 6 of these for a total of 2400 watts of solar for my camper. I decided it was better to have these portable panels than to mount solar on the roof so that I can park in the shade and put the panels in the sun. These are the lightest panels of their size I've seen and they are pretty easy to setup. I am in the northeast US and have not gone to any lengths to get "ideal" placement, but the best wattage I've gotten out of these is a little over 300 watts per panel - which I'm totally ok with. I imagine that if I aimed them better and were father south I'd get a higher output, but as I said, I'm very ok with what I'm getting. It takes me about 5 mins to set them all up, and when I'm travelling I keep them in the shower of the camper. I originally got 3 of these, and then I got 3 more of I guess the newer version.

I had high hopes for this panel. 400 watts for substantially less than other 400-watt portable panels. Alas, it was too good to be true. Testing it from 11:00 am to 1:00 pm on July 6th when the sun was highest in the sky, no clouds (but slightly hazy) and the panels reclined to their maximum to match the solar inclination.... I only got 228 watts maximum (very briefly) with an average of 200 watts at 39.6 volts. That 57% of rated capacity at the maximum output and 50% of rated output on average. Compare this to the 200-watt panel (name brand) that I already owned that produced between 88% and 93% of its rated capacity at the same time and set up the same way. Otherwise, this seems to be a well-made panel. The connectors are good. The packaging was good although shipping was a bit slow. Its price and output are mostly in line with 300-watt panels. I just wish it was what it was supposed to be.
