4 watt works better than the 8 watt panels
Great product, even though the first one I bought warped, and died after about two years. Used every day in my truck, as it is parked unless camping or picking up lumber or jerrends like that. I purchased two 8 watt, and they have to be in exactly the right spot to charge, which means you have to keep moving it also and have a meter to check. (Major return problems). That is why I bought this 4 watt again, and is working great.

🌟🌟🌟🌟🌟 **A Reliable and Efficient Solar Charger!**
Just to note - this seems to fail about every 18 months - I hope this one doesn't do the same again The Sunway Solar Car Battery Trickle Charger & Maintainer is exactly what I needed to keep my 12V car battery charged and maintained. The solar panel is compact and lightweight, making it easy to position on the dashboard or windshield with the included suction cups. It’s super easy to set up—just plug it into the cigarette lighter or connect it directly to the battery with the alligator clips. I’ve been using it for a while now, and it keeps my battery in top shape, even during extended periods of non-use. This is a great solution for maintaining batteries in cars, boats, or RVs. Highly recommend for anyone looking to extend their battery life and avoid unnecessary drains. ⭐⭐⭐⭐⭐

Cracked case in under 2 weeks
3 star review for the housing breaking apart from heat. Had for less than 2 week and it cracked other than that it charges my vehicle as intended will have to wait to see if it’ll stand the test of time or if the cracked case is due to internal pressure and failure of the product in time.

Sunway Solar trickle charger
Nope. This charger is a parasitic drainer. It drained my battery in just two days after connecting the alligator clips to the battery terminals. It has no diode to prevent drain even though it claims to. Do not buy this charger nightmare.

Works great!
I love this little thing! It adds just enough to keep my truck charged and ready to go. I generally park with my truck facing away from the sun so I place the solar panel in the rear window and run the wire to the socket on the dash (continuously on) which works perfectly.

Trickle charger that works year after year
I am a snowbird, when I come home in the early spring, my truck starts right up. Plug it in the cigarette lighter put it in the windshield. See you in six months. Battery is fully charged when I get home.
