a more of a vehicle/car battery maintainer.
if you have a plan on storing your vehicle/car or will not use it for a longer period, this one is good. it keeps the battery charged and you will never have to worry restarting the engine.
pls note, this will never charge a dead battery.
This charger has a long cord about 8-10 feet. I have a trailer I keep my bike in. The panel can be mounted like a slotted key hole but I sat mine on the roof and ran the wire through the side door and inserted in my power outlet. No more removing seat and battery cover to jump it off during bad riding months. My battery would only "click" the starter and two days later it had enough charge to start. Really surprised me as it is not intended to recharge battery just maintain charge. Overall works great. Great price too. Found similar charger on china import website and was same price. Would like to see optional alligator clips for direct battery applications such as lawn mowers, ATV, autos with switched outlets, etc.
The solar array doesnt have a blocking diode in it... a 4 cent, IN4007 diode would have kept this from draining everyone's batteries by preventing the electricity from flowing backwards through the system at night/low light when the solar array wasnt forcing power through the system... but they couldnt be bothered to do that. So it kills your battery.
Bought this to keep my boat battery charged. Hooked it up for the first time exposed to full sunlight. Came back a week later and my battery was too weak to crank the engine.
I usually unhook the radio wire so the radio clock/preset current won't slowly drain the battery. I figured that the solar charger would be enough to compensate for this small draw without having to disconnect the radio every time, but apparently the charger doesn't have enough output to even keep the time set on the radio. Either that or it is actually draining the battery. Anyway, it's not doing what I bought it for.
The solar cells are protected from breaking better then the one I just broke. The blinking light only means "charge" as in the panel is getting sun, it shows nothing about whether or not current is going to your battery, (misleading description). I put in my own circuit to indicate when current is actually going to the battery.
Used to Maintain classic car battery while in storage. Measured 20 volts and 4.5 amps on a sunny day.
The product did not work at all. The indicator light flashed for 1 second on first use and then never again. Total disappointment.
the led on the charger flashes saying it's working, gets a minimum of 8-10 hours of direct sunlight (I live in San Diego) but I didn't notice ANY difference in the charge of my battery on my seldom used vehicle. I'm returning it...don't buy it!
The Wagan Solar Power Battery Charger provides a trickle of energy that will keep your car battery topped-off with enough power to start your car -- as long as you drive it every 24-hours. Depending on what type of problem is causing your battery to drain when the engine is off, you will still have to drive your car regularly to fully re-charge the battery.
In my experience, the trouble lights on my dashboard will not turn off, ever. That small amount of energy drain was enough to leave me with a battery too weak to turn the engine over. After a jump-start and a 40-minute drive, I put the Wagan Charger on my dash, parked the car in a position where it would get the maximum amount of sunlight during the day, and plugged the charger into my car's power outlet (the old "cigarette lighter" outlet.)
When I went out to start my car the next day, the Charger's red LED light was blinking, and the car started with no problem. I discovered, however, that I needed to take my car for a spin AT LEAST ONCE EVERY 24-HOURS, or the battery would drain away. I skipped one day of driving, and my battery was stone-cold dead the following day.
This is something that I would have liked to use, but my car's 12V slot requires a key
in the ignition. Have not used, but will keep.
After the panel was bought, I was waiting on a friend for an hour or so, popped the panel into the sun side of my van and listened to the radio, even had a fan going the whole time. Van started up just fine. would be great for tailgating, sporting events and camping.
Recieved the charger took it out of the box,, saw that the red LED was flashing and pluged it in to my lighter and left it on the dash.Checked it after a couple of days and the light was not flashing.Took it apart to check for loose or broken wires,and found none.Checked the LED on another charger and it would flash,so it is the charger,not the LED being burnt.For all I know the thing did not last 5 minutes!!
I plugged the battery charger up in my truck so it could charge the battery.
I let it charge for 1 week. When I tried to start my truck the battery was more
dead than before.
Almost a weeks I have this wonderful product and yesterday I have checked my car working wonderful. Great so far. :)
works well and does what I expected it to
The only draw back I have is you can't connect it directely to the battery.
Maybe I just got a lemon and the solar panel works fine otherwise. The one I received didn't charge my battery but discharged it within a week or less despite being in a sunny state. I hated to have to send it back and won't go for a replacement even so it would've been the cheapest, easiest and most economic way to keep my battery topped. So I'm back to the wired trickle charger/maintainer which runs from a 120 V outlet for now and maybe I give it another try at some point with the same (if I find out that it worked fine for other customers) or try another brand.
Easy to operate and reasonable cost Perfect!
This product drained my battery instead of charging it. So I took it back!
waste of precious money and time.
