Rated 4 out of 5 by from No more flat battery (after 6 months) Yes, it would be nice to have the reassuring LED, but I have tested it with a multimeter whilst plugged in and can get about 180mA in good sunlight. It does drop somewhat (to about 40mA) when the sun goes in - despite the description stating it only needs daylight not sunlight? Also, what's that other review about it not working in a garage over the winter? They didn't state if the garage had windows or not!? Mine is left outside and just happens to be south-facing and 6 months later, never had a flat battery. Had to wire my aux socket to a permanent feed but it's all been worth it.

Rated 5 out of 5 by from Fantastic product, keeps my boat batteries in good condition all year round. What you spend on this will save you double every year if you run more than one battery on your boat and find yourself replacing them every year!

Rated 2 out of 5 by from Bought this after reading many favourable reviews and it worked a treat. for a few weeks. Problem was that, for no apparent reason, the glass cracked, rendering it useless. Cannot understand what caused this as it was onthe rear shelf of an empty stationary vehicle so could not have been knocked. Maybe just bad luck but under the circumstances I could not recommend the product.

I am thinking of this to charge a car battery used to run a thermostatically switched greenhouse heater. Can it left connected permanently while the heater switches on off through the winter?

Asked by: Shortjock
I would recommend using it in conjunction with a solar charge controller.

Is there some sort of protection so it doesn't over charge the battery past 14V ?

Asked by: Chris1804
The solar cell does not feature any overcharge protection. The amount of energy generated by such a cell is typically just enough op replace energy lost through natural dissipation and keep a battery healthy. You should always make periodic checks on a battery on charge and never leave a battery charging unattended for long periods of time. If you wish to incorporate overcharge protection then the use of a charge regulator would be recommended.

I accidentally left it in the cigarette lighter while turning the ignition on to move the car about three feet. Is there *any* chance that it has not been overloaded and broken?

Asked by: SNP83
Yes, there would be a chance of this.

Is this panel fully weatherproof ie can I leave this outside all year round exposed to wind, rain, hail, sleet and snow

Asked by: Boardy
The item is not IP rated so we would not advise leaving it outside all the time, it will be unaffected by slight rain, but heavy rain or settling snow would damage the item.
