This also makes it an ideal accessory for a beach party or a picnic. A small portable solar charger would be enough to power a cooler to keep your food fresh or to keep the beers cold. I am sure we will even see some coolers coming out shortly which have built in solar panels to operate them. The solar panel would most likely not need to be larger than the lid itself, and could be incorporated onto the cooler.

Such solar panels in even in small sizes provide enough solar energy to power Ipods, MP3s and cell phones and lots of other small devices. If you are spending the day on the beach, this would most likely cover all your electrical needs.

You may find further information on the types of solar chargers available at solar charger grid.
