  • Works on my boat.

  • Great Solar Charger
Size: 20W Color: White
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 to charge my four wheeler battery
Size: 10W Color: White
Mounted it to the outside of my polebarn to get adequate sun. Has a blue light on the back of the panel letting you know the sun is there. Has a red light to let you know it’s charging and a green light to let you know it’s fully charged. And the material is somewhat flexible.

  • It's working well.
Size: 10W Color: White
Something is drawing down my battery very slowly and I've not yet been able what it is. Now, the car might sit for a couple weeks and it starts right up. I'm going to need to find and fix the problem before the snow comes, but now I can procrastinate for a little longer.

  • Works GREAT!!! Just what I was looking for!
Size: 10W Color: White
We purchased this to put on our boat to keep our battery charged. Have had it for several weeks now and it works perfectly for what we wanted. Keeps our boat battery fully charged without overcharging it. Turns out the 10V version was large enough for trickle charging between trips out.

  • Works great!
Size: 20W Color: White
All you need to charge your 12v battery! I bought this for our adventure van that only gets driven a few times a month. The kit came with various connection options and in our case we just plug it into the charging port on the dash. I accidentally left the interior lights on one night and in the morning the battery was dead… with just this solar charger we were able to start later that day! Worth every penny! ... show more
