CDRKING Solar Energy Kit

CDRKING Solar Energy KitCD-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.

Charge controller connected to usb hub

One problem with the solar kit is that instead of providing a standard usb port to charge your gadgets from, they use a proprietary connection and then give you adapters for a few different phones. Fortunately, one of those adapters ends in mini-usb which means you can connect it to a standard usb hub and then connect any usb device to the hub.


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.

    I agree, but we all need to realize that adding Solar on their house is an asset which could boost the actual worth of their property if / when they choose to sell. With the environment the way it is going we cannot overlook any item that delivers 100 % free electricity at no cost to both the shopper and more importantly the environment!

    Hey Ericus, it looks like cdrking have already discontinued the solar kit that you linked to. The newer model of my kit is

    If you can get the panel placed in a position where it will get a full day of sunlight then expect an average of 3-5 hours of light per night. Otherwise expect much less.

    I’d personally recommend buying a 10-20 watt solar panel on sulit, a 12v 7Ah battery and then some cheap 12v LED bulbs and some connecting wires. It will cost a little more but it will give you better capacity and faster charging times.
