Product overview

• Keep your battery topped up with solar power, even if the weather is overcast
• Ideal for cars, caravans, boats etc
• Interchangeable connectors: accessory socket plug and crocodile clips
• Blue flashing LED charge indicator
• Durable ABS outer casing
• Built-in diode prevents reverse charging
• Suction cups for easy mounting

Designed to trickle charge 12V lead acid batteries with no additional running costs. Ideal for cars that will be left standing for long periods, as well as for maintaining batteries in caravans and boats. The built-in blocking diode prevents reverse charging from the battery to the solar panel at night.

The solar panel can be connected directly to your car battery, or used through your 12V accessory socket, and will slowly trickle charge the battery. It is not designed to charge a battery completely from flat, however will maintain a battery by keeping it topped up when it is not in use. For larger vehicles with bigger batteries consider using a higher wattage solar panel.

Rated 5 out of 5 by from I read the other reviews a couple of weeks ago before I bought mine. They are mostly spot-on. I did hope that this would work via my cigarette lighter but was not surprised when it didn't. However I can sit the panel on the dash and I run the wire around / under the passenger door and then under the bonnet of my Alfa 159. Only a couple of inches of wire are visible outside the car?????? and the battery is topped up. I would recommend the solar panel to other people who have a car where the battery is exhausted by the drain from the alarm etc. over a period of a couple of weeks or more.

Rated 5 out of 5 by from This is a well made product, the interchangeable adapters (cigarette lighter and croc clips) allow connection directly to the battery circuit or via car cigarette lighter socket. It is not waterproof, but using the plastic case that all the parts were in and sealing it in the case, it has been outside several rainy days without any problems. It has a slow charging rate, but it only rated at 1.5w charging spec. so it is to be expected. It will maintain a battery at full charge when the battery is not in use and this Electricity is free! :-)

Rated 5 out of 5 by from Very good solar panel, it works even in daylight. I think it uses a voltage regulator built-in, as seems to be able to keep the voltage around 18v no matter on the amount of light (in reasonable lighting conditions - e.g cloudy day. I Have tested the voltage and it seems to be around 17-18 volts, which is a good voltage for charging 12v batteries. I have it permenantly connected to a small 12v 6ah lead-acid battery which runs a small inverter. From a day of charge in mild sun on window (after voltage gone down for inverter to cut off), I can run a 20watt fan for around 40-55 mins, or charge my mobile up fully. The average power I recorded from this panel in mildly sunny conditions is around 500-600mah worth of charge - meaning every day it puts 0.5 of 6ah's into my battery. You get a good length of cable - around 2-3 metres.

Rated 5 out of 5 by from This panel is ideal for trickle charging my diesel car battery that is used very infrequently. It maintains sufficient charge so that even while the car alarm and Immobiliser systems are working continuously the battery remains in fully charged state. After fixing the panel to the inside of the window using the suckers the cable can be trapped in the wound up window and run under the closed car bonnet. The winter months still provide sufficient output.

Rated 5 out of 5 by from I got one of these for my 1972 VW camper van after having starting problems due to a low battery- and it works great. I leave it plugged in for long periods over the winter and it always starts first time. When away camping i connect it to my leisure battery which is ideal if you have one as you can keep that topped up too. Would highly reccomend!

Rated 5 out of 5 by from Bought this to charge up a portable 12v power pack that I was taking camping with me. Great product, robust, simple to use and comes with all the connections you may need. Simply attached to my powerpack during the day and trickle charged until later on in the evening where we then connected some outdoor led fairy lights, which then illuminated the tent until bedtime. Were also able to charge our mobile phone during the day. Great price, great product...

Rated 5 out of 5 by from The best tenner I have ever spent, just plug in and forget it ,with the piece of mind of knowing the battery will be fully charged when you next go to your car, great for when you leave your car standing for the 2 week summer break.So good I purchased on foe my elderly father,easy to use and no hassle. Great product highly recommended.

Rated 1 out of 5 by from Waste of a tenner!!! I bought this on the odd chance that it would work and after a sunny week we have been having it has failed to keep my motorbike battery topped up. Being off work for 4 weeks, my motorbike will be locked up all that time. Having a tracker and alarm fitted to the bike, I don't want the battery going flat. I bought this on Saturday and installed it on the bike. On Monday I checked the battery with a multimeter and got a reading of 12.25v. Not bad I thought. Went to check it today and got a LOW reading of 8.9v. A complete joke. I checked the charge rate of the solar panel with the multimeter and I am only getting a range between 6.5-7.8v of charge in direct sun light. Useless. Will be taking this back for a refund.

Can I connect my solar trickle charger and my electric trickle charger to my car battery together. The idea is to have a back up in the event of a power cut. Many Thanks. George.

Asked by: GEO 1
No, this would not work.

I need a trickle charger to maintain a 12 volt 110 amp/hour battery in a caravan. This charger does not appear to have a charge controller, is there any risk of overcharging the battery?

Asked by: Hal47
it will maintain a battery by keeping it topped up when it is not in use. There's very little risk of overcharging the battery. You may however require a larger wattage panel for a large amp/hour battery

Is this item weatherproof, could it be used on a garage roof for example and is there anything to prevent it overcharging a car battery?

Asked by: Ned K
No, this is made to be on a dash inside the car and it is also not provided with a charge regulator.
Answered by: Dominic
Date published: 2017-08-15

can this panel be placed outside? Or can it only be used on say a car dashboard?

Asked by: Solarlemming
This item is not weatherproof and is for use behind the glass.
