EF ECOFLOW 160W Portable Solar Panel for Power Station, Foldable Solar Charger Chainable with Adjustable Kickstand, Waterproof IP67 for Outdoor Camping RV Off Grid System

INCREDIBLY POWERFUL, STRONG AND WATER RESISTANT - USED OFF-GRID IN THE UKThis panel is amazing. It produces up to 400W in direct bright sunshine but can produce as much as 40W even in heavy overcast in a UK summer with light rain falling. In very heavy overcast and heavy rain it will not work (obviously) but this would be a tall order for any solar system. I have used it in constant rain in the Lake District and Wales this summer, and been so chuffed that it continues to gather power in sub-optimal conditions.I have been blown away by how much energy you can harvest from the sun with this thing and though I am late to the party if I had more money to invest I would be buying an EcoRiver solar panel system for my house. The initial cost is high but it is more than worth it. This panel recharges my EcoRiver Delta 2 at full power (400W) in around two or three hours from flat. In overcast conditions it takes 6-8 hours to recharge the battery from 50% to 100%.The panel was able to endure the very strong winds and very heavy rain from Storm Betty recently while on holiday. I did have it attached using strong paracord to two strong trekking poles as a support system and it was carefully guyed down to strong tent pegs. At one point water was gushing along the panel, which was oriented uphill, forming a small river around 4 inches high. This is well beyond the expectations for water resistance for the panel and I was suitably amazed it survived - the electrical connections are sited about half way up the panel. The carry case is very good at doing just that - but perhaps not so good as a panel support which is its secondary use - see below.Suggestions for improvementThough this panel is amazing it is not superbly supported by the included case which doubles as a support system for the panel. The end result is a panel which sags and is not fully flat when angled using the case. I corrected this as described above by tying the corners with paracord to trekking poles but this was not a perfect solution. The powered, automated solar tracking support made by EcoRiver is an astonishing £2600 on their website (nearly £1000 more than the cost of the Delta 2 and this panel together!!) so I will be finding a cheaper solution to support the panel better. Some sort of lightweight but strong metal frame might be a good way of supporting the panel and in my view should be included in future versions.Additionally this is a very large and heavy panel. At 16kg it is uncomfortable to carry more than a short distance by hand and is large and unwieldy to put up - best done by two people. You don't get something for nothing - all that power has to come from plenty of surface area - and I don't regret buying this one bit. I will hopefully get years of use from it.

We bought the Eco-Flow Delta 2 power bank and needed the solar panels to with it, so we thought we’d buy Eco-Flow. They are simple to erect and even have eyelets so you can secure them to the ground and they are stable once up. It depends on how much sun you have as to how quickly they charge and you have free energy when you need it without needed to be plugged into a service pitch.I also like that you receive a bag with your purchase to keep the panels in when not in use, not every brand does this. I’d highly recommend purchasing these panels, you’ll not be disappointed

I am very pleased with the quality and performance. The only reason it did not get 5 stars is because it did not come with a lead to link it to the Delta 2 I bought at the same time. Having had both items shipped to my holiday destination ready to be off grid I then had to wait another four days before I could use it as I had to order the connecting lead. The solar panel arrived with a note to tell me what to order but it would have been helpful to either know in advance it to have it included in the order.Now looking forward to happy camping with the ability to charge cameras and other holiday gadgets with ease.

Does what it claims. Very happy with product!

Great item. Work well and easy to store and transport

Early use but this panel feels very well made and I am hoping that it will last a long time. I am using this with the Anker 757 power station as I only want to use a single panel and this one is about perfect with a rating of 220W. The supplied cable plugs directly into the 575 and it started charging as soon as connected.Early May and I am seeing 160 to 170W in direct sunlight. I am hoping that with attention to the angles and a better day I could see a number approaching 190W. Should be good to charge from 50% to full in 4 hours.*Edit* Clear sunny day and it produced 178W allowing for a 62% to full charge in 2.8hrs (as per image) Not sure if I will see 180W but I will keep on trying

I purchased the Ecoflow Delta 2 along with the 220Watt Bifacial Solar Panel after a lot of research and YouTube watching. What can I say, apart from “WOW what a piece of kit”. I wish I purchased one sooner. The Delta 2 doesn’t have the biggest storage capacity in the Ecoflow range & haven’t used it to its full potential so far. Just charging Phones, Power Tool batteries, Laptops etc. It has surpassed my expectations. It was very easy to set up, the App is straight forward to set up & use. The first time charging it, I was always checking the power input from the panel, which at times exceeded the 220 watts. The other day I was charging the Delta 2 at the same time I was charging two Power Tool batteries and my Phone with no problem.

It’s a solar panel, what to say? Works however the ‘stand’ is infuriatingly bad.
