If you have a car that isn’t used often enough to keep the battery healthy, this is the perfect solution. It is a solar car battery charger that trickle charges when set in the sunshine. It can just sit on the dashboard or in the rear window and charge the car battery whenever it is not in use. An LED light blinks to indicate the charge. If you have problems with the battery gradually draining, this will keep it topped up. However it is not intended to recharge batteries that are totally flat or compensate for faulty batteries, so don’t expect miracles!

Hot sunny days should be spent outdoors, not staying inside with the air-con on full blast. But sometimes when the heat is unbearable, those lazy summer days on the porch just don’t happen. This outdoor misting fan could be all you need to bring the temperature down enough to enjoy lazing on the porch again. It connects to a standard hose and emits a fine mist as it blows. It effectively cools a wide area by as much as 25 degrees and is very energy efficient. It has three speeds and a one year warranty.

When you need to measure small quantities of ingredients, such as spices or oils, ordinary scales, even digital ones aren’t much use. That is where this little green gadget comes in so handy. Simply spoon up an amount and get a digital reading on the handle, so you know exactly how much you have got. Even better, the measuring spoon is solar powered, so there is no battery to run low and give a dodgy reading. Leave it on a sunny window sill when it is not in use and it will be charged and ready to go whenever you need it.
The TC-11 – solar digital spoon scale currently costs $18.99 from MiniInTheBox
