stuck the panel up in the moon roof window and plugged into the center counsel cigar lighter which is always on. This means I don't have to worry about battery discharging when the car is left in driveway for a long time. Nothing is outside and I don't have to remove it when driving. Will see how long it lasts.Update after a few weeks: works well.

Like other posters I am a believer. I have a 2009 Honda Accord EX sedan. My car sits and its parked outside. I put the solar panel on the dash and hook the battery cables and it does the rest. It shut off when the battery is fully charged. If it is still hooked up, sun is out and the battery is drained in anyway, this will automatically turn on and start to trickle charge as needed. I will buy another one for my wife's car. Before this I had to drive my car about 30mins for the alternator to charge the battery. I only need to do this in the winter time, I dont have this issue in the summer time.

The simple steps below will protect you from discovering unpleasant surprises after it is too late to return the panel.(If you don't have an multimeter/ammeter, or you are not comfortable using one to measure current or direction of current, get help. There is no point in damaging your meter because you don't want to ask for help.)BEFORE YOU ORDER: With the car turned off, doors and trunk closed, and lights and accessories unplugged or off, unhook a battery lead and use an multimeter/ammeter between the battery and the unhooked lead to measure the parasitic current draw when your car is asleep. Whatever that number is, multiply it by 3 or 4 to allow for overnight draw and cloudy days. So if you measure a draw of 1 amp, you should purchase a panel good for at least 3 or 4 amps output. (YOUR NUMBERS ARE NOT LIKELY TO BE THAT LARGE, I WAS JUST MAKING A SIMPLE EXAMPLE) If in doubt about which panel to buy, it doesn't hurt to have a little extra capacity to account for aging of the panel, multiple days of bad weather, and exaggerated output ratings from the manufacturer.AFTER YOU RECEIVE THE PANEL: STEP 1: First, in full daylight use an ammeter between the solar panel and the battery to verify that it is working and providing something close to the current output you expect. This is also a good way to find the optimum location for the panel. STEP 2: With the panel in full darkness (covered, at night, or both) use an ammeter to verify that no appreciable current is flowing from your battery to the solar panel.We all want to do things the quick and easy way, but these are fairly simple steps that will help you avoid problems and get a successful result. I hope this is helpful to someone.

I have a 2014 Prius which can sit for a month before I am back in town. I bought this trickle charger to keep the 12V battery from going dead, like before. I bought an extension cable that runs from the solar charger which sits on the dashboard to the 12V battery in the back of the car.So far, it has kept my battery alive for the past 3 months. 4 weeks is the longest the car has sat without being driven. The car is in Southern California so it gets a fair amount of sun. The picture shows a green light that I saw when I returned, 4 weeks later.The green light means the 12V battery is fully charged. I leave the trickle charger plugged in when I drive, but I take it off the dash because it will easily fly off if the suction cups are not being used.I will have to see if it will continue to keep the battery charged up enough during the winter months when there is less sun.

I got the first one to keep the battery charged on my 2004 Jeep Grand Cherokee that I drive on occasion and is parked outdoors with the alarm on. It's worked so well I bought I second one for my 2000 Cherokee since I bought a more fuel efficient daily driver. Yeah, I could pull both up to the shop and put my trickle chargers on 'em, but that's a pain and blocks my shop doors. In over a year I've have had zero issues and CAR BATTERIES are expensive. With the alarms on both, the batteries are always charged and the Jeeps are ready to rock without having to drag out the big charger or expensive booster, running a cord and always worrying that I've compromised the existing battery.Having said as much, I just put the panel on top of eithers roof and let it do it's thing. I do not use the suction cups and have not tried it mounted inside either vehicle.

This unit is a serious upgrade from the 10W model! It is of much sturdier construction, and works in lower-light conditions. One important new feature: the LED is on the face of the board, not on the back, as on the previous model. This means that if you mount it permanently, as I do, you can still easily see the light display, which indicates the panel status. It cost a few bucks more but it is definitely worth it.
