straight out the box i got 43.9 voc pretty good i meed the 400w that us the thumbs up the flimsy frame and legs not so good they hold the panels up ok would do far better mound on a solid frame using the gromits the folding velcro flap to keep it folded while carry is below the handle could c9me lose and unfold best to use some straps to secure it little heavy not bad its about the with of my renogy 200w solar suitcase and 2" short on length the renogy is a solid frame suitcase i like the positive 400w so over looking the velcro and flimsy design will build a frame to support it better good for the price when needing 400w for bluetti elite 300.

so far so good. it is heavier than I expected but will be easier to bring on camping trips easy to set up and use. the output is a little less than a fixed panel but it's ease of transport makes up for that. the extra wire connector makes it useful for my different battery packs

Great product welled package and worth the money no I don't get paid for this review this from real experience and this is the second item I purchased from this company and I haven't had any type of issues with them and I highly recommend others to give a chance

I haven't measured the wattage but it does perform well in the two weeks I've used it. it's plenty of power to keep my 100a lifepo battery charged which powers my 12v fridge, assuming I only use it as a fridge. turning the freezer section on draws more power than the 200w panel can produce in the few hours of light we get in October. I can deal with that. decent value

This portable solar panel outperformed considering the affordable price. I got @ 300 watts on an imperfect sun day. Folds easily, not too heavy. Happy with purchase!

I've been watching these solar panels for some time now. I waited until the industry settled on the same wires. This solar panel is what I expected and there were no surprises. Depending on what devise you want to charge up, you will probably need to get an adapter kit for some of them. I found one for $10.00 and just keep it in the pocket when I need it.

300w max is all I've been able to get out of them - full sun, mid-day. Good portable backup/add-on system.

Panels are awkward to put out,a little flimsy. Had I known, I would have just purchased 2-100watt systems. Had to purchase wiring fitting to work with my Jackery.

This is a 300 watt panel, not 400 watts as claimed. When tested, the solar array underperforms at 300 watts, though advertised as 400 watt capacity. Isc = 7.5 amp tested, Voc = 42.5 volt tested = 318 unloaded watts tested, in full sun at noon. Actual Imp x Vmp is 10% lower at <300w real capacity. That said If you're okay with only getting < 300 w total output, you will be happy with the build quality.

This product arrived with half the panels not working, and after a day's use with very light handling, a 3rd panel went out. This item breaks too easily.
