EF ECOFLOW NextGen 220W Portable Solar Panel, Bifacial Design Up to 25% Conversion Efficiency N-Type Solar Cell, with Adjustable Kickstand, IP68 Waterproof, Foldable for Camping/Home Backup

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

Gotta love harnessing the power of our sun and being able to use it for free these solar panels are perfect bifacial too which means you get energy from both sides which is great when you need it most they are super easy to set up too and I love that they come in a protective carry case

Work very well on our Delta 2 Max for camping

Bought a Delta 2 & EcoFlow Solar-panel 2 years ago for camping trips. A nice bit of kit, but the firmware/software is glitchy, e.g. loses Bluetooth connectivity with the App, has to be reinstalled, & firmware updates are often problematic (read the forums). The one star is because of very disappointing customer support. 6 weeks into a 12 week camping trip in France & Spain and the Delta 2 stops working. After trying all the usual fixes, I contact Customer Support, in summary, their support is: 1. Turn it off & back on again. 2. Update the firmware (this had already failed, after several attempts, I provide the error code.) 3. We’ll send a replacement to your UK address, in 7-15 days. I explain my situation, currently in Spain, half way through a 12 week camping trip & relying on the Delta 2 & Solar panel to power my fridge, etc. In summary, replacing my Delta 2 outside of the UK is not in warranty! I am now altering my trip & paying for Electricity. Thanks EcoFlow!

Pretty good , bit of a hand full moving them around

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

Been using this now all summer and getting an average of 1800 Watts over 10 hours worth of "Sunshine" in my back garden without bothering to keep moving it for optimum angles etc. I did once see 202w of power coming through around 1:30pm when it was probably at its best angle. I then use this electricity to charge my Bluetti AC200 Max (yes a different make but still compatible), The Bluetti then powers my entire home office. Laptop, 2 x Ultrawide Monitors, Router (running all the time) and lamp when required. Plenty of "free" energy that cost a fortune to invest in the first place, but probably I've saved around £200 over the 7 months or so that I've been using it. I am considering investing in a 2nd panel purely to double the usable power in winter as I'm only getting the sun for around 4 hours now in October.

Still experimenting. But in weak sunshine (over cast sky) it's challenging around 5% an hour. Waiting for a bright sunny day to test out its full pontential.
