CD-R KING have carried a range of solar products for quite some time, from small keychain solar torches to larger backpack USB chargers. It’s only recently (early 2012) that they started carrying full kits that include the panel, a solar charger and battery. This means that you can collect the power of the sun during the day, store it in the battery and then use it at any time, day or night.
I chose the p1990 solar energy kit which features a 4W 9V poly-crystalline solar panel, a charge controller with built in 3500mah battery and three 0.8W LED lights. The charge controller also features a 5V DC output for charging phones, mp3 players and other small gadgets. I chose this kit over the more expensive ones because it includes the 5V DC output which the larger ones (at the time of writing) do not.
Solar Energy Kit Performance
After using the kit for a week, I can confirm that it does exactly what it says on the box. To get the best performance from the solar panel, it needs to have direct sunlight; mounting it on your roof would provide the best results. However, it does manage to charge the battery even in indirect sunlight.
