20W Solar Panel Kit with USB Output Ports, Portable Solar Charger for Car, RV, Boat, Cell Phone & More (20w)

Looks to be of great quality. Charged my batteries up no issues so far. 100 watts and flexible too!

I have no idea what half of these reviews are for, the reviews don't match this for this solar panel 20 watt. Some of these panels come with no factory sticker describing power specs, manufacturing is also inconsistent with the red light that suppose to turn on where usb c jack is located on back panel, the red light comes on in sunlight to let you know panel is on. Sometimes on some panels red light is missing. So far all panels worked, but good to have consistency in manufacturing. At least have the brand and spec sticker on back of panel, on many panels this is missing. Why ?I like the power output for a small 20 watt panel, reads 25v dc in full sun unloaded. Panel is flexible to a point, but be careful with panel if you hear crackling noises, youve gone too far in flexing it. The panel does deform and warp a little in hot sun, so good to mount this on a stronger flat surface like a 1/8" panel plywood. I suggest not glueing, just use scew holes to mount it. You need some air flow underneath all solar panels. Maybe a few spacers 1" thick under screw holes to raise panel a little and get air flow.Appears to be very effecient solar panel, absorbs any source of light even on cloudy days. Great for keeping your vehicle battery topped up. And easily charge your phone or tablet. With a few more of these 20 watt panels you can charge a solar battery generator and keep it topped up in a full charged state.These solar panels are Affordable, are effecient, but time will tell how well these hold up. It has a descent warranty.Again this isn't waterproof but can be made waterproof by sealing the back usb c charging and wiring holes on plastic box housing on back of panel. It has a dc barrel plug for 12v battery charging. However this panel and more panels can be wired together, then it can and should be used with a good MPPT solar charge controller for faster, safer lifepo4 battery generator charging. And it would be good for much faster 12v lead acid vehicle battery charging.

I got this for my hen house I immediately noticed it had wires showing that would make it not work after one rain. Meaning it's definitely not waterproof. There was also a hole in the solar pannel box where the wires come out. I taped the wires with black duck tape and thought id try to mount it. I wanted to mount it on nothing but chicken wire. So I was going to zip tie it especially since it came with zip ties. But I soon realized that there were no holes on the front for the zip ties to go through from the back. And the screws hold the metal cage on it. So I have no idea how I could zip tie it. I tried going in through the blades and it won't spin. I was maddddd. And then I realized that the caged side is where I the wind comes out but the back is exposed. There's a warning not to stick your fingers in there. Not good. So how am I supposed to put this tiny fan on the hen house facing the house without the run having exposed to blades. These fans are tiny they are the size of a pen. I doubt they would do much wind that's why I wanted it for my smaller area hen house. I do not recommend these because you won't be able to do much with them. The only thing I like is the cords are very long from the fans to the solar panel. Do not buy

Worked well I would get around 12w to charge a battery but stopped working right and got a hot spot

The 1st pic showing it charging power banks. It can other small devices.Pic 2 is the shows the back side. The connector in the back for the accessories in comes with. (Haven’t used them)Pic 3 is the output amount. It comes with 2 USB ports, but depending on what you want recharge it will recharge 1 at a time. It says 12v/5v but I think its only 5V. Unless that’s for the wire connector in the back.Pic 4 shows the thickness of the panel. It’s thin and can be easily stored and carried around. I sometimes tie a weight on the corners in case of windy days.Other things to know: it still recharges in overcast and shade. Comes with suction cups so if you could attach it to a window or a parked car window (under the sun). Great to have if you go camping.Month worth of testing:The power bank is a 26000mAh and takes approximate 24 hrs of sunlight. A 24000mAH will take 14-18 hrs. A 8000mAH will take about 4 hrs. An iPhone SE 1-2 hrs. A whole day can charge a tablet 65-85% (remember to turn off any applications in your devices).Overall its a great to have. I just wished i got the 20W instead.

I purchased this panel and fans for use inside of my greenhouse. The system was much smaller than I expected, so I decided to use it on a shelf where I keep plant seedlings. It usually only turns on when the sun is very bright and will not run in early morning or afternoons. So far after a couple of months of use it is still working.

I purchased this panel primarily to power a small 12v fan I salvaged from a computer, to dry out herbs and onions in my garden shed. The fan is rated at .63 amps and runs like a champ with direct power from this panel. I also tested the usb charging ports, and both will recharge my iphone, going up by a couple of percent in a minute or two. My secondary use will be to charge power banks. The USB supply sits on the back of the unit, and has two open slots, so I'm not sure how well they will hold up if exposed to weather, but the rest of the unit is thin and slightly flexible. There is no bulky metal frame. There are 4 mounting grommets, and the unit comes with both a couple of carabiners and 4 suction cups which fit in the grommets for mounting on windows or smooth surfaces. This appears to be well made, of reasonable quality and with good performance.

This thing is thin and flexible enough that it can be wedged in between the frame and pack of a Mystery Ranch Terraframe 80 and would fit inside of probably most 50+ L packs. The USB box seems a bit fragile but I like that it has a 12V output. I took a small USBC fast charging power block and 3m taped it to the back of the panel and plugged it into the 12v supply. This panel will fast charge a phone or power bank if the sun is right. Kept my devices charged on a 4 day hike.
