Rated 5 out of 5 by from Bought two of these briefcase style solar panels as they were on offer and are currently being used to keep a 12 Volt 7 Amp/h lead acid battery topped up which powers a set of 16 colour LED mood lights with remote i also got at Maplin rated at 2 amps on the power adapter. I converted the connector on the lights to clip to the battery and the lights run fine on the battery and stay lit all night without changing much at all in brightness, but i may need another one as the battery's voltage never gets over 8.8 volts after a full day of sun on them both, but despite the lower voltage they can still keep it going just fine but just not as bright.

Rated 4 out of 5 by from It seemed to work OK and kept the battery alive, but after a spell of hot weather the casing became warped and cracked from the heat. Since it is not weatherproof It has to be used inside the car where it is subjected to high temperatures during hot weather. The plastic used in its construction is not sufficiently heat resistant.

Rated 5 out of 5 by from This is an excellent piece of equipment. I bought it to keep my camper van battery trickle charged. It does an excellent job and is so neat and compact and looks very cool. LED light to show it's charging and built in diode to prevent battery draining. Works very well in the highlands of Scotland - even on cloudy days. I am so glad I bought this on offer - half price - what a bargain.

Rated 3 out of 5 by from My Dad bought me one for my car to top up the battery. It works well. But after 7 months of use, the wire that plugs into the cigarette lighter has become brittle and broken off at the plug. Disappointed in the quality of materials used.

Rated 4 out of 5 by from Looks to be working fine the problem I had was that the crocodlie clips were made from tinfoil and bent when putting onto battery terminals but I took them off and used round spade connectors and permenently fixed them to battery all seems to be ok hope battery will be good when I go back to caravan and be able to use motor mover

will this charge an iPhone & a quatix watch

Asked by: lollo
This would be unlikely to output enough to maintain a reasonable charge as the maximum output is 4W, iPhone charging wattage would be 10W. This panel would be used more to top up a battery which would be used to charge devices.
