Features

  • Charge Visualization:The indicator lights can help you understand the charging status: the blue light is on (put in the sun), the red light is on (charging), and the green light is on (charging is complete).A short circuit occurs and all three indicators are off
  • Intelligent Protection:Built-in charging microprocessor, improved charging algorithm, can provide overvoltage protection, overcharge protection, short circuit protection, etc. It can prevent reverse charging and can be safely used for charging and maintenance of 12 V batteries
  • Higher Conversion Rate:The regular convex points of surface distribution are conducive to the secondary propagation of light, absorb the radiant heat of solar energy to a greater extent, and greatly improve the photoelectric conversion efficiency
  • Widely Used:The included three-pieces SAE cable kit is plug-and-play,it can be used for cars and 12 V batteries. Comes with carabiner and suction cup to meet your different installation needs. Suitable for automobiles, RVs, motorcycles, ships,snowmobile,etc
  • More Durable:The PET material can be waterproof and dustproof. A layer of epoxy board is added as a bottom plate, which is more sturdy (the broken panel will cause the charging efficiency to decrease). You can contact us at any time if you have any questions

    • Functionality
Color: black Size: 10W
IMHO. I think every vehicle on land and water should have one of these. We all depend on our battery to crank a vehicle or boat but sometimes something goes wrong. This product is great for keeping your battery top off at peak performance at all times. I highly recommend.

    • Stopped working after 2 months (Or so I thought) [UPDATED REVIEW]
Color: Black Size: 30W
Original Review: At first I really liked the panel, I have a Bluetooth adapter that reads battery voltage and I could see the charge go up if I sat there for a few seconds. I was checking voltage regularly (every 2 or 3 days) to make sure it was keeping my battery at the properly charged, which it was. So when I finally decided to trust this and not be checking it so often, it stops working. Now I have a dead battery and will have to pay to have it replaced. Not happy. Updated Review: Let me start by saying that the reason my battery drained was not this solar panel's fault. Turns out the Hands-Free Link module in my car had gone bad and was draining the battery even when the car was off. Once that was found to be the issue, thanks to a friend that has the same car I do and coincidentally started having the same battery drain issue too, he told me what was causing and how to get to it to unplug it to test if my HFL module was draining the battery. After the HFL module was unplugged I then though to take this solar panel out from storage and check, I had not used it since I labeled it as "bad" but never got to throw it away since I thought it did put out some power just not enough for my car. Well now I can say that my car can sit indefinitely, the battery will not die anymore and has not gone bellow 12.3 volts even after 3 weeks of the car not being used. ... show more

    • Doesn't like the elements
Color: Black Size: 20W
Used as a battery tender for my car in storage. Works great if you leave the solar panel on the dash but it doesn't like being in the elements if you put it on the outside of the vehicle. Barely had it a year and it no longer charges. Completely dead. It worked great when it did work though.

    • Great charger
Color: Black Size: 20W
Perfect go to charger for my golf cart, four wheeler or side by side batteries. Super easy to use and monitor progress. Fast charge and good value! Lightweight too!

    • works perfectly
Color: Black Size: 20W
Picked up to keep the battery charged in a second vehicle that is rarely driven. Battery would be dead in a week or so. Plugged into power port, and set the panel on the dash, and after 3weeks, the engine turned over and started easily. Measured it at 18v at 1.5amps. Would buy again. Panel is super thin, but tough and slightly flexible. Really pleased with the performance and quality. ... show more

    • Bad Fuse in cigarette plug-in.

Arrived on time. Eager to hook it up to my C5 corvette, I was disappointed to see there was no "connection". My trusty voltmeter detected no continuity in the + lead. Visual inspection did not detect the defective fuse. Replaced the fuse at my expense and with the wrong size for now. Uses a 5-amp 250 volt. I only had a 10-amp 250 volt. It now is showing that it is connected and charging. Yes, I will get the proper fuse Amazon at my expense. ... show more
