AA 12 V Car Solar Battery Trickle Charger, AA1432 - for Vehicles and Caravans - Battery Connectors Included, Solar 4.8W, Black

Reasonable price. The OBD plug seems to be a rare feature on these solar panels. It is needed because some vehicles dont activate the cigarette lighter socket unless the ignition is on. This is a well thought out product. Kept my motorhome battery charged during April. I accidentally left a cabin light on for 2 weeks and this saved me from a flat battery. Good quality item.

This solar panel car battery trickle charger is a useful device for keeping your car battery topped up when parked for long periods of time.The panel is the size of a dinner tray and is quite robust without being too heavy.It connects via the OBD socket which is usually located just under the dashboard. This socket has direct connections to the car battery which are not affected by the ignition being turned off.I would recommend this item.

useful for harvesting solar energy to keep 12 volt battery charged. Inside the car windscreen in direct sunlight it pumps out just over 17 volts.

I have a Stop/Start SEAT, battery went low and wouldn't start the car.But it had enough power to shut windows/lock car/fold mirrors.Sat over weekend 2 1/2 days to be precise, mixed weather.Went to it on Monday morning, started straight away.I was apprehensive on buying it, but on advice I bought it.100% recommended.

The instructions are rubbish. But, it's not too complicated so not a real issue.As for the charger, it does create a charge. Sort of. The more sun it gets, the more charge it generates.... but even then it really is a tiny amount. Even less if there is any tint on the car window, clouds in the sky or just a lack of strong direct sunlight. Will this stop my car battery going flat if I don't use the car for a while? Not a chance in the winter months! It'll just give me a little extra time. A very little extra time. In the summer, it might just about cope.At best, this 4.8W panel is okay for a small car. My car has two 12v batteries so I'll probably start looking for charger with a safe and reliable 20-30w panel.

Does what it says on the box we'll and of good quality build in a light weight package.

No use at all. I have tried on 3 different vehicles and they drain the battery rather than charge. Do y bother get a plug in trickle charger instead my car spent 2 days at the dealer to rectify faults caused by this.

OK so far. Very easy to connect. I like you don't need the battery , just the EOBD connection. Bought for motorhome, which just got a new battery, so trying this as the garage said it was one option to preserve it when not using.
