I wanted to be sure I had more than enough power going into my Delta Pro and Extra Pro Battery, especially if I am on the move or need to power my 3D printers for an outdoor event. Leaving the panel out in prime sunlight made it charge the batteries as I was 3D Printing. This means I was 3D Printing with ZERO CARBON EMISION! That's amazing!! I'm seriously considering making my whole business run on ECOFLOW Batteries and Solar Panels from this one experience alone.

I purchased this item a few weeks ago, but have not had the opportunity to use it yet. I am a novice camper. I can consider myself a first generation camper or explorer in my family. But even though I only have a few camping nights under my belt, I was impressed with the information that I was exposed to online from the reviews of other customers and fellow campers. I really enjoyed the idea of winter camping and I am sure that the solar panels in conjunction with the EcoFlow Delta 2 which I have also recently purchased will be a great combination. I am planning on creating my first YouTube video which will consist in the unboxing of the 400 W solar panel from EcoFlow as well as the EcoFlow Delta 2. As part of a winter camping video series based on New Jersey’s state park campgrounds. I am very eager to see the results of both products. Hopefully, I will inspire other family members to enjoy the beautiful outdoors as well as the different EcoFlow products.

These panels have far exceeded my expectations. I use these panels in conjunction with my Honda ES2200 to charge my Ecoflow Pro which in turn supplies power to my RV Trailer. The panels typically supply 250 to 275 watts on a sunny day leaning against my trailer. When laid out more flat to the ground I've seen as much as 380 watts. These panels are heavy and a little pricey, but I believe it's money well spent and plan to purchase at least one more set..

You know how you bump elbows with someone on the sidewalk and they put a little brainstorm in your head, well thats what led me to buying the Delta Pro and the "Extra Battery" .. I use it exclusively for charging my Tesla (I don't have a garage, or access to electricity in my carport) .. Perfect solution for everyday driving for me ...

The solar panel works as it's supposed too. Gets close to the wattage, if placed correctly in the sun. Charged my EcoFlow Delta within 3 hours from 50% on a sunny and warm day. I did have an issue with the kickstand and had to prop it up using outdoor furniture, but I'm assuming that was user error. :-) One of the accessory hooks broke, but they replace it very promptly.

This pane has been my go to panel when charging my devices. i average around 375 t9 384 watts which is very good. i now own three of these panels and i would highly recommend them to anyone looking for a large foldable panel with this much solar output. Do not just take my word for it try one and see why I love this panel so much.

Solar panels are great and provide faster charging than I thought they would. They are extremely heavy however and I was unable to move them around well. Also, they are floppy and it is difficult to easily reposition them for sunlight. If you are not very strong and small in stature, you should consider a smaller panel set.

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%.

The panel itself is a bit bulky (42lbs) if you make a brace it works very well I have gotten up to 385 watts of power. And the panel is robust. The down side to this panel is that it takes 6 to 8 min to set up. And the team that designed the stand never tried to use that piece of crap I have 3 of them modified all of them so I don't have to unfold or use the terrible stands .

The case to be used as a stand is a joke. I couldn't get it to work for me at all. I opted to just lay the panel flat on my back deck. The sun hits my deck from around 9am until 6pm. It is July so I'm sure that will change, but for now it is working for me. With all that said and done, I still am able to produce up to 310watts. I'm very happy with that. My TV, and my gaming laptop and 2 fand and 2 phone chargers only pull 170watts. So I am able to game and charge other items and have no worries of using more power than I am producing..
