Review for: Portable Solar Panel 280W/20V Foldable Power Station Lightweight 24% Efficiency Charger with IP67 Waterproofing with MC4 Conversion Plug for Camping
UPDATE after 1 month on the road at bottom of review.
>WARNING: Be careful, check your charging system specs before you purchase this HIGH VOLTAGE solar panel!
This appears to be a well built solar panel. The kick stands work well and are better than the other two similar panels I have. This panel is big! About 8 feet long, 2 feet wide. Pretty heavy also, not to the point of hard to carry, but it should stay in place better with wind than the other two folding panels I own. The storage pouch is larger than the two other folding panels I have, but there was less in this large pouch.
The advertisement shows “wide compatibility” in photos (as of 24 April 2024), and has the word “adapter” in the title, that lead me to believe that there are adapters included to attach to various kind of battery pack. Nothing like that in the package I received, only MC4 connectors, no adapters.
>One star off for misleading advertisement.
The Amazon advertisement says “Maximum Voltage 20 Volts.”
Inside the storage pouch on the panel, it says maximum power is at 23 volts.
Manual says: Open circuit voltage 27.4V. Working voltage 23V. Operating current 11.8A
Measured panel voltage is higher than the advertisement says. Checking with a meter in 10AM late April southern Wisconsin sun, I get over 35 volts open circuit. Short circuit current came in at 12.5 amps, and a good size spark on my meter leads.
Hooked the solar panel to my (very much NOT recommended) “ECO-WORTHY 12V 20A DC to DC Charger with Solar Charge Controller” I saw ZERO CHARGE. With the charge controller connected, and zero charge current, I measured 28 volts on the solar panel. I assume the very small load of the charge controller was pulling the voltage down. Still, that 28 volts is three volts more than the eco-worthless controller would accept, according to Eco-W’s specifications.
>Two stars off for panel voltage being too high.
Hooked the panel to my little “Energizer 293W Portable Power Station” it did charge, but that unit is limited to 60 watts solar charging so using this panel does not make sense for such a little battery pack.
Our camper is in for repair or I would have tested the panel with that charger. The charge controller in the camper says it is rated up to 45 volts input. Once we get it back and have a sunny day, I will update this review. Unfortunately, that may be several weeks (late May?) as I will not be available to do such tests for a while.
UPDATE: We used this panel for a month in southern Utah. Sun was strong most of the time, charging happened fast. As long as your solar controller can handle the higher voltage this panel produces, it appears to be a good one. One thing I really liked is the panel produced electricity even without full sun, cloudy days still provided a few amps charge.
Would I actually purchase this panel? Probably not, to expensive. One star added back since the panel did the job I wanted it for. Be aware that this panel is rather heavy, however that helps it stay in place when the wind kicks up. We had some high winds (winds to front of panel) and the panel never moved. I will be keeping and using this panel.

Have been messing with small scale solar for years, gradually expanding system to help in case of Florida extended storm related power outages. This new setup was nearly instant, quickly placing on ground and connecting with cables to an existing solar controller. Even without best placement for sun, it produced more power than existing fixed 300 watt roof mounted system! Being so light and portable, I did move it a couple times during the day to somewhat center it for best results. Clouds also did not hurt it as much as roof mounted system. Surprisingly excellent system!!
Only downside was included cable and connections. Being portable, I guess it assumes fixed MC4 to the spare included XT60 cable was all that is needed. Would be nice if a few other options were included. Most users should already have methods to connect to various cables anyway, so not a deal breaker by any means.

I got this for a little solar charger i received and this has worked pretty well for it. I am getting about 50-80 watts consistently into my rechargeable power station so i am quite happy with the results so far. It is quite large and folds away quite flatly. It was honestly a lot larger than I thought it would be for 100w but i am glad to have it as backup solution. It is also a little heavier than other similar sized solar panels i have but not terrible.

I am new to portable solar power devices, so I’m not sure if things I noticed are significant or not. Between the ad, the instructions, and the panel I found three different numbers for voltage produced. I didn’t do any measurements, I just hooked things up and watched them work, which fortunately they did.
The kickstand supports worked well to hold the panels up, but I’d like to know what is inside the fabric cover of the kickstand. Is it something that will fall apart if it gets wet? I had to buy an adapter to connect the panel to my camper solar plug, as well as a set of extension cables so I can move the panels instead of the camper when the sun moves. Folded up these panels aren’t exactly light, but at a little one 20 pounds they’re not difficult to move around.
I recommend these solar panels.

Used this to charge my giant backup battery. Got it fully charged in about 2 hours of full midday sun. Couldn’t be happier!

The Yolaness 100W solar panel measures 21″ x 24″ folded and opens to be 21″ x 48″ and weighs 8.02 lbs. It has a built in power puck that provides connectivity to MC4 connector, USB-A and USB-C ports. No output specs were provided for the 2 USB ports, but I assume they are standard 5V.
In testing the panel in bright sunlight, 83 degrees it showed an impressive output of 113W which is excellent. I like that build on handles for easy carry and having the MC4 connectors which makes it easy to connect to my equipment. It would be a good choice for camping, boating and other outdoor activities either standalone using the USB power to charge/power USB equipment or with a portable power station making also ideal for power outages.

Pretty skeptical about these at first but it seems to be great, looks big not sure if it’s powerful to charge up a whole solar generator yet but great for camping and charging phones and smaller stuffs so far. Can be quite useful for festival camping
