Website didn’t mention solar panel works better outside of windows. Had a strange problem with power coming from the panel when I plugged into the cigarette lighter the door locks wouldn’t lock ? They worked when I unplugged it. The car has an electrical drain somewhere and that’s why i wanted to try the solar panel. I’d say the panel was ok maybe a problem with the car 🚗

I bought two for the batteries on my boat, and I am very happy with them. They are solidly built, and work exactly as advertised. I took a chance because they don't tell you how long the wires are, and was happy to find they are about 9 feet long. Good product.

Reviewed in the United States on February 22, 2024

Color: Solar Powered Battery Chargers 20wVerified Purchase

This solar panel charged up my battery and with a inverter you can run some appliances. The higher the wattage on inverter more things can be used for example a NuWave cooktop and this solar panel will keep your battery charged 😀 👍.
Must have, period. For outings, camping, fishing, picnics or for emergencies-power outages, hurricanes, tornadoes or earthquakes. Gonna get a couple more panels and a couple of lithium batteries and I'm set, of course a higher wattage inverter. This item is NOT a luxury it's a necessity. Portable and easy to handle. Only draw back is that it has to be sunny, clear and super sunny otherwise forget it. Obviously forget it if it's raining, dark n cloudy or any other obstruction. For the most part a great item to have.

I've had this for about a year now and it works great. I've got a small trickle charger that won't charge a fully dead battery. Hook this to it for a couple hours and it's good to go again. At least enough juice to use my other charger. I have this connected basically year round to my dump trailer and it keeps the battery strong whenever I need it. I'm planning on buying more.

Color: Solar Powered Battery Chargers 7.5w-BVerified Purchase

POSTED Review mid-Jan 2024. I bought this in April 2023 and in late November the LED light stopped working after heavy rain. I tried drying it out during December but it is still not working. It constantly shows a red light even when it is bright daylight and even at night and it is connected to a battery.
UPDATE: A day or so after placing this review, I was contacted by UK_POWOXI - Amazon Marketplace and without any questions they immediately dispatched a replacement unit which I now have.
This level of service is a mark of a good reputable trustworthy firm.
PS This is a good piece of kit that delivers a consistent voltage above 12V, I just measured 15.1V
