Travel Solar Charger – Light and Portable

Saturday, September 10th, 2011

This is a well designed solar charger that has had good reviews for its performance overall. It has useful suction pads so it can be fixed to the window in a bus or car and charge in the sun as you travel. For long trips the internal battery can be charged before you leave from a USB cable and then kept topped up by solar charging fairly efficiently. It isn’t designed to reach a full charge solely from solar charging, but certainly gets enough charge to power ipods and other devices. It has LED lights to indicate the remaining power level. An additional feature is its LED flash light / reading light. Altogether this is a slim design that is perfect for traveling.

Solar Dragonfly Lights Add Charm To The Garden

Tuesday, August 23rd, 2011

These pretty accent lights are just the thing to add to your garden for night time color and charm. There are three dragonflies in each set and they connect via cords to a solar panel, which charges during the day for up to 10 hours illumination at night. The dragonflies are colorless when switched off, but automatically switch on at night and glow through a rainbow range of colors, constantly shifting for a magical feel. The only drawback is that there don’t seem to be replacement bulbs available, so after a couple of years, when they usually give out, you would have to replace the whole set. But they are very pretty clustered among the flower beds, and the kids will love them!
Set costs $34.95 from Gardeners Supply Company.
