Arrived in good shape but output has degraded over months
The product arrived on time and is as advertised. I had never worked with a solar charger and was able to begin charging the battery on our camper within 10 minutes of unpacking it. The quality seemed appropriate when considering the low price point (but not great). Initial performance in direct sunlight was approx 55 watts, which seemed acceptable and was able to charge the deep cycle battery on my travel trailer relatively quickly. While the thin, light design is nice, the panels come with no mounting system or stiff backing so the flex of the panels makes them difficult to position. Thin loops around the outside are helpful, but are not strong enough to support the panels if suspended and pulled away from the supporting object to provide and appropriate angle to the sun. After several months, we brought the panels on a two week trip. We never used them on the trip, but since returning the performance is less than half of the original performance. I have wiped the panels down and looked for a damaged cell (which I don’t see) but am unable to restore the original performance. My guess is that they were damaged, but believe I will look for a replacement that is more durable.

Works great
Came with sealed package, build quality is good, on a sunny day it changes two phones without issue, my iPhone charges from 5% to 50% in about one hour. I don’t have a tester to see exact power output but it does do what I need. I like its functionality the charging cord has a multi adaptor could charge for different types of devices. It is a convenient portable solution for my poolside.

So far so good. Definitely buy cable extensions as the ones that come are short. Product looks good. Haven’t had time to use it a lot yet.

🔎 Overview 🔍Perfect emergency solar panel or camping solar panel if you plan on being in sunny remote areas. I was not able to get super accurate measurements of charging speeds so I will put it in terms of how fast it charged my iPhone 15 Pro from 20% under sunny conditions. When fully unfolded and facing directly at the sun, the panel was able to charge my phone from 20% to 95% in roughly 45 minutes. It also was able to charge my iPad and numerous other small USB devices. The size is rather large and may surprise people how big of a solar panel is required to generate just a little bit of energy.I would happily recommend this foldout solar panel to anyone who is planning on charging their devices while camping in remote sunny areas!

I am a little bit of a solar geek. I started playing around with solar about 8 years ago on a camping trip where electricity wasn’t going to be available. I still wanted to shower in my trailer and run my CPAP machine at night. I started out with one monocrystalline panel that was huge and unwieldy, a charge controller and a 12-volt battery. It worked, but it wasn’t ideal. I’ve been adding to it ever since. I can’t believe how much solar has improved even in just a few years.This panel we are reviewing today, for the price and for it’s size is pretty much ideal for a weekend camper who is looking for something small enough to pack, but big enough to power all their devices. Combine this with a power bank of some sort, and a nice sunny day and there is no reason why you shouldn’t be able to stay fully charged.The panel claims an output of 110 watts. Very impressive for its size. The thing is, usually if you read that fine print that number is based on optimal conditions and other factors that make it very difficult to achieve. Not so with this baby. I took it out for a test drive. The day I checked the numbers there was some light cloud cover. I would say about 90% sun. I measured the voltage output and found with the panel tilted on it’s kickstand facing the sun it was putting out about 25.4 volts. A tad high for a 20-volt panel but within spec. I then checked the amperage. It was putting out 3.89 amps. Now applying the old formula (yes, I remember something from high school) Watts = Amps x Volts I got 98.8 watts. Almost 100 watts from a panel that wasn’t even in full sun. As a guy who has played with various solar panels over the years, I’m here to tell you: That’s impressive!The build is really good. The magnetic snaps hold it shut with just the right amount of force. The carrying handle is a great touch and the built-in pouch holds all the accessories you should need to charge just about any device. I use an adaptor that connects directly from the Cerrxian connectors (standard solar connections) to an SAE connecter and then to my charge controller, so I didn’t need most of the provided connectors, but if you plan on using this to charge a portable battery box you’ll likely find everything you need in the pouch.Overall, I found the quality to be great. It feels well thought out. I’m super impressed with the numbers, and the manufacturer has provided all the necessary cords for most people. The price is really good with the 20% off coupon applied. That brings it down below $150 (at the time of my order) that is a really good deal for what you get.I really like this product and yes, I would recommend it.
