   To use on newer Jackery units, I had to get the DC7909 to DC8020 adapter plug.

   以前100Wのパネルを使っていたが充電能力が落ちてきていた
   こちらは200Wとパワーがあるので安心して充電できる。
   ただ、重量が10㎏ちょいと重いので持ち運びには一苦労する
   普段は車に入れての移動なので良いけど
   キャンプサイトと駐車場が離れているときは大変（＾＾；
   でも一度設置すれば防水IP67なので多少の雨が降ってもそのままでOK。
   設置場所は車のルーフラックに広げている。
   サイトでは冷蔵庫、扇風機で電源取り充電ではPC、スマホ、LED照明くらいしか使わないので
   充分余裕である。

   This is the best portable solar panel available, made from exceptionally high-quality materials that make it resistant to bending and breaking. It features a rubber-like coating that protects the solar cells from deteriorating over time. Unlike my other solar panels, which began to chip after a week, this one feels and looks incredibly durable. Even at full price, it outperforms its competitors, but when on sale, it’s an exceptional deal. I use it with my Anker F1200, where it reaches 375 watts on bright days or hovers between 280 and 330 watts, allowing for faster charging. Highly recommended for anyone seeking a heavy-duty 400-watt solar panel.

   I have used quite a few foldable solar panels, and this one is my favorite so far. Very sturdy backing, very good solar cell performance. Currently a sunny day for testing, and I consistently get over 140W and sometimes with as much as 175W. Hard to beat, highly recommended.

   Edit: Well, a couple months later and the wires attaching to the panel broke off. I cut the fabric away to see what was up, and it’s just two little solders and some rubber insulation, very cheaply connected and not built to last. The panels themselves are great, but the wiring is bad. This one goes in the Dumpster, and I no longer recommend.

   Edit: Nurzviy identified the problem, and offered to repair/replace the panel. New one works great, and I might add they have fantastic customer service. This panel is sturdy, easy to set up, gives great wattage output, and is again my favorite portable/foldable panel offered here. Thanks!

   This panel puts out about 320-350 watts per hour in full sun (for the engineers out there- this was measured in early November in Southern CA. Readings were taken every hour and the panel angle adjusted to maximize output). It increases the charge on an EcoFlow 3600 Watt generator about 7% per hour using a 25 foot cable. The EcoFlow started at 5% at 8:30am and stopped charging at 3:45 pm (no sun) with a 59% charge. The only negative is that is fairly heavy and doesn’t come with a great stand. I have used 200 Watt panels and the. I really recommend this high output panel.

   Open circuit I had 23 volts In almost direct sun In West Texas. This Is a solid built portable solar panel that I have yet to hook onto my Jackery 1000 or anything else, but the volt meter doesn’t lie. I feel like It’s a good value for the money. I also think that they are probably all made at the same place with a few variations. Some have a few more attachments, some are different colors and some of the ones cheaper than this one have less solar cell protectant sheets. I almost bought one for $168.00 new off ebay, but at about $25.00 more, this one had more protection and was close to 10 pounds heavier. This Is the second one…my first one arrived In a box that had been opened and looked to have been a returned Item. It was missing parts and pretty ragged out. I sent It back and they replaced It with no problems. I almost didn’t ask for a replacement but now I am glad I did.

   It works better than I expected.
   It’s just as described, couldn’t ask for more from an item.
   It’s well built, gives out great charging power. It’s a little bigger than I expected, but not too big. It’s definitely a great value for the money.

   What I did find (I’m new to color panels), is that it gets hot. (I mean I sits in the sun, so I should have expected that.) So I learned quickly that I needed to plan to give it some cool down time before I out it back up. But it cools off pretty quickly on the shade too.

   Great addition to my echo batteries.
   

10. NoviceTech Verified Buyer – 17 April 2025

    I got 140 watts with my DJI 500 on the 200 watt solar panel, I said that’s not to bad.

    Power output is as advertised. Unit is heavy-ish, and therefore not portable, but it is easy enough to throw in the back of your vehicle and set up where you may need it.

    Build quality seems to be pretty good, however, the grommets at the top are ripping out and once they are gone, I have no attachment points and it may become useless unless I just lean it against something.

    Also, don’t count on the case working as a stand because they are too heavy and it’s flimsy. The newer version supposedly has solved this problem with better stands, but I created a collapsible PVC pipe stand with T’s and 90° elbows that seems to work OK

    The lack of a good stand, but mostly the grommets coming out is why I wouldn’t give it higher stars

    It looks pretty study with 22.6% of claimed efficiency. I managed 160W out of afternoon sun in non-ideal angel as the kickstand is not really adjustable. I would say the value is to charge my battery from 20% to 80% in a day of full sun, i.e. 600W / 160 ~= 4hr.
