EF ECOFLOW220 Watt Portable Solar Panel, 25% High Conversion Efficiency N-Type Solar Cell, NextGen Foldable Solar Panel with Adjustable Kickstand, IP68 Waterproof for Camping RV Off Grid System

As a Hawaii-based outdoor enthusiast, I'm impressed with the EcoFlow 220W Portable Solar Panel. Its portability and durability make it perfect for beach trips and camping adventures.The panel's performance is outstanding. On a sunny Hawaiian day at 12:05 PM, I recorded a peak input of 206 W - that's 93.6% of its rated capacity! This efficiency translates to faster charging times for my devices and power stations.Setup is easy with adjustable kickstands, and the panel is compatible with various devices. While it's pricier than some alternatives, the build quality and performance justify the cost.For those serious about portable solar power, the EcoFlow 220W panel is an excellent choice. It's become an essential part of my outdoor kit, consistently delivering reliable energy under the Hawaiian sun.​​​​​​​​​​​​​​​​

Thin, lightweight and works well

So far the Ecoflow solar panels have been the best purchases of all the panel I have bought. Their output is very good and they are durable. They are also portable and are very high quality. They are a little more expensive than other brands but in this case you do get what you pay for.

Just returned from 2 weeks camping in the boonies. This trip was powered by two Ecoflow solar arrays totaling 440 watts. The power plant was the 2048 watt cd Ecoflow Delta 2 Max. This setup flawlessly ran lights, TV, music, device charging, phones, and all my Dewalt tool and camping accessories. Just what I’d hoped for…Changing out propane bottles at week two, I had the opportunity to put the fridge and water heater on solar. It held up to the task, but it put a dent in storage. Not unexpected, but I needed to witness the drain. All around - we were pleased, and likely to create a stack of these for larger camps, parties, weddings, etc. No complaints so far.

started out great! but 7months later and it's limping to the barn.I suppose part of the problem is that it was never meant to be a daily driver?I think the most I ever got out of it was 175w but now I'm lucky to get 75 on a fully sunny day and while I realize that to achieve the 220, I would have to operate in the vacuum of space, I really didn't think it would go below 100 Watts...ever!!I know humidity plays a factor, but still, 1/3 of the supposed output is subpar in my book.

I've used this solar panel for three months now and it seems to be well made and I haven't had any issues using it. I had some questions regarding solar panels and power stations and customer service was very helpful. I like that the solar panel is portable and ease to use. I know I'll likely never get the output advertised, so with that in mind ... I live in Phoenix AZ at it is around 1pm and I'm pulling in around 180W. Overall I'm happy with my purchase.

These are powerful panels that even in winter provided 200-205 watts close to the rated 220 watts between 10 and 3pm in SoCal. The built in stands and sun angle guide used to position the panels for optimal exposure are easy to use. I'd recommend using sand bags around 10lbs each to secure the stands in windy conditions. I bought some Aimosen sand bags here on Amazon. They fold up nicely and store in the included zippered bag.

The Ecoflow 220 Watt Portable Solar Panel does charge my Ecoflow Delta 2 power unit but it almost isn't worth the hassle. The biggest issue is the poor mechanical design. The panel is indeed portable and folds up. The problem is that it doesn't stay unfolded, and it doesn't stay positioned. There is nothing to keep the panel sections horizontal to each other and they tend to fold inward. The feet to position the panel are almost useless. They barely manage to resist the weight of the panel itself, and have rather weak elastic straps to keep the feet from folding under the panel. A bump from a small animal, uneven ground, or wind can move the sections of the panel or make the whole thing collapse to the ground. This "portable" panel also has no provision for better mounting or a better stand. A few dollars worth of extra plastic or metal and some mechanical engineering could have avoided the problems. If you plan to use solar often, this panel is a waste of money. Buy some other panel, and buy the necessary stand or mounting hardware. For infrequent use, it is tolerable, but probably overpriced considering the poor design.
