    • Good product
Size: 20W Color: White
So far so good. Attached it to my RV battery as per the instructions and it seems to work. Not that much power, but enough to extend battery life when I don’t want to run a generator. The suction cups are pretty marginal, but the panel works well.

I've been using the SUNAPEX 10W Solar Car Battery Trickle Charger & Maintainer for a while now, and it’s a great way to keep the car battery charged, especially if you don't drive it every day or if you live in a cold place. The solar panel is lightweight and portable, so you can easily take it with you wherever you go. It's also waterproof, which is a big plus. The charger is easy to use. Just connect it to your car battery and leave it in the sun. It will automatically start charging your battery. The charger also has a built-in overcharge protection feature. I've used the charger to keep my car battery charged when is cold outside and I don’t go out, and it's worked perfectly. ... show more

    • Easy to install but be aware that it would be easier to install if suction cups were taller.
Size: 10W Color: White
Honestly it works so that is the main thing. The only improvement they should make to it is to provide taller suction cups to attach it so it wouldn't have to bend backing material because circuit box plastic gets wedged between backing material and glass of windshield. I don't actually attach suction cups to glass because I don't want to stress backing material since it has the solar panel on it. Kind of an obvious error in fitment that would be caught if they had tried to install it on a glass surface. Still charging works great so that is the most important point to me. I would give it 5 stars on easy to install if it had taller suction cups. I just rest it against the propped open hood to charge and don't use the suction cups to hold it. Those using it for long term use may find this to be a reason to look for another model or think about dealing with the too short suction cups issue?? You've been warned about an issue on an otherwise great product. Product works great in actual use trickle charging battery. I have the 10W model. I don't know if all size panels have the same suction cup issue or not? ... show more

    • Very easy to install, works without direct sunlight, though is most efficient with direct sunlight.
Size: 20W Color: White
I am using this to maintain the batteries in the semi tractor I use. As a warehouse manager I have a semi that gets used to run materials out to large construction projects, as well as shuttling trailers in and out of docks as needed. Our tractor can set for days at a time between uses. Using a solar charger / maintainer frees up an outlet and keeps the batteries fully charged and ready when needed. During warm weather when the tractor does not need to have its block heater plugged in, we can park it anywhere and keep the batteries fully charged. ... show more

    • Great Solar Charger
Size: 20W Color: White
Review Image by Invoxicated Invoxicated
My experience with solar chargers started about a year ago. I had a 5 watt charger that a friend had given me for my generator battery. I never used it for that. Fast forward one year later - I have since retired and my truck sits in my driveway a lot more than it used to. My battery kept going dead so I tried the 5 watt charger and waited a week to see if it either worked or if my battery was dead again. To my surprise it worked! My truck started right up but the problem was that the old battery was 4 years old at that point and I knew that this was going to keep happening unless I either went back to work or I was going to keep the solar charger on my truck battery. The sun and the heat warped my 5 watt charger so I needed a new one. I saw this one and it was on sale at the moment I purchased it here on Amazon. You should know that any solar charger you buy will be subjected to extreme heat and light so please keep that in mind when you buy one of these things. I recently went to remove mine during a hot afternoon and nearly burnt myself because the unit was so hot after being on my dashboard in the midday sun in front of my dashboard heat shield (see pic). 20 watts seems to be the limit for a solar charger before it needs a separate controller to regulate the flow of power to what whatever it is you're charging. Also for those who care at 20 watts the charger is putting out about one amp of DC electricity which would be the equivalent of a trickle charger output from a battery tender. I like this unit because the solar panel is flexible instead of being rigid or made from hard plastic like my 5 watt charger. The holes in each corner give you the flexibility on how you want to position for maximum sunlight exposure. In my case I laid the panel down on my dashboard and put my big sunshade behind it to protect the dashboard and interior of the truck from the heat and sun fade. The sunshade keeps the panel propped up for best sun exposure. I didn't write the review until I tested it out the same way I tested the 5 watt panel, by waiting a week to see if my new battery (Northstar AGM- NOT RECOMMENDED due to it going dead within 10 days of inactivity and VERY poor warranty support-see my review) would be able to start my truck (Nissan Murano). The Murano has a 3.5 liter engine, not a big engine by any standard yet I have to keep a solar charger on it in order to prevent the battery from draining on me. The charger has been on my truck for about 3 weeks now and whenever I decide to go for a drive my truck starts right up with no issues. I disconnect the charger before I start the truck and when I come home I reconnect it. A bit of a pain in the neck but it guarantees that my truck will always start no matter how long it sits in my driveway I can see this charger might have other uses too. It could be used in a camping situation to charge battery packs or an emergency situation as well. The only minor quibble I have is that the panel does come with a small controller attached to the back to let you know that the charger is charging. There are 3 lights on this little controller. One to let you know that it's receiving sunlight so that it can function. Another LED to let you know that it's charging whatever battery you have it attached to. Then there is a third LED, a green one. Once an item is fully charged the green light is supposed to come on. I have yet to see this green light come on but the charger does work as it's intended. Update 5-29-21- The green light on the controller does appear to function! I noticed the other day after having my truck sitting with the charger attached the green light on the back of the solar panel was on! Apparently my battery must have been low and it took time for the charger to top off the battery. Highly recommended -------------------------------------------------------------------------------------------------------------------------- I rely heavily on reviews when I make purchases so I put some time into reviewing everything I buy on Amazon for personal or business use so I can help other people considering that item.

    • Works Great
Size: 30W Color: White
I have tried 10W and 20W panels from other brands and this has worked the best, hands down. I charge a pair of 45aH 12V batteries, and it will keep them topped up in sunny Colorado, no problem. The flexible panel is tied down on my boat and is pretty tough. It was not the cheapest, but worth the money! ... show more

    • Drained battery - recommend adding blocking diode on positive charging wire if you want to use it.
Size: 10W Color: White
Seemed to work great during the Summer but when Winter came, it seems to have completely drained the battery of a parked car. Tested it outside of the vehicle and the controller on back of panel would not shut it off when the panel voltage got below 13 volts and instead would start a battery drain. On Winter days there is more time at below 13 volts than above. Have now added an external blocking diode to the positive charge cable to prevent the battery being drained by the panel and will see how that holds up. ... show more
