Allpowers Portable Solar Car Boat Power Solar Panel Battery Charger

Had it on my Seadoo all summer - routinely in the past I had a low charged battery when reaching October but not this year - every start all summer till pulling out of the water in the Fall was strong. Recommend as a trickle charger/maintainer - will not charge from a dead battery. Works as stated.

Lo uso para mantener cargada mi batería asta hora vavien

Great product works as advertised. I have a Dodge Durango that doesn't get used to often and every now and then I usually start the car to charge the battery, but somehow forgot over the holidays and it drain down to nothing. So before I charge my battery and the traditional sense in plugging it into an actual car battery charger, I decided to get this solar maintainer and see what it does from an absolutely dead battery. I let a charge for one day, and later that night when I put the key in the ignition I did get a beep and then the battery died again. So after that I let a charge for two days, put the key and I heard the beep because the door was open, and it actually beeped A bunch of more times, but when I tried to actually start the car, of course it didn't start and I know that shouldn't happen at all. After that I let it charge for five days, and pretty much the same thing happen when I let it charge for two days. If anyone knows something about this please send a message or add a comment to this, the alligator clips that clip on the positive and negative are very thin metal, I wonder if I cut those off, strip the wires, then wrap the bare wire on the battery terminals if I would get a better connection and that would help or is it just simply the fact that 5 W is nothing compared to an actual car battery?****update 7/31/15****So honestly, it barely works with just one. You notice it, but it's not Tremendous! So I actually bought 2, 1 each for two cars. I went ahead and connect both of them together at the same time to one car. I didn't think anything of it, and didn't use/ turn on my 02 Durango for two months straight. Needed to move it the other day, when I started it up, BAZINGA WHAM BAM there it goes! She turned on so powerful I couldn't believe it. It's like as if I just installed a brand new battery. YES, it's true. I just bought two more for my other car ;)

Purchased for charging boat battery while using or not for our trolling motor. Works great. Purchased another to try on ATV battery.

I bought this for emergency use. I'm afraid that there will be no electricity on the road when driving, which will help the car to start engine. I haven't had the opportunity to use it outdoors yet. But I tried it once at home. The operation is relatively simple. It would be better if it comes with a protective cover.
