Review: Smart Power Strips

Justin — Mon, 28 Apr 2008 20:04:34 +0000

I’ve been testing a surging-protecting power strip called the Smart Strip by BITS. The Smart Strip works like this: it has a “Control Outlet” which controls six other outlets on the power strip. If you plug a computer into the Control Outlet, and it turns off or goes into sleep mode, the other “switched” outlets on the strip will be turned off. (more…)

Solar Powered 12 Volt Battery Charger

Solar powered 12 volt battery chargers are small solar panels that trickle charge your car’s battery while the sun is shining.

Basically, the solar charger provides a small amount of power to the battery, so that if you leave your car’s door open you won’t be left with a dead battery.

This reminds me: I’ve always wondered why cars don’t incorporate a small switch to turn off interior lights and headlights if they’ve been on for say a hour or two.

The best 12V solar charger I’ve found is the Sunforce 50012 1.8 Watt Solar Battery Maintainer. You can plug this 1.8-watt solar charger into your vehicle’s 12-volt lighter socket and position the panel to pick up the most daylight possible. Or, if you prefer, use the alligator clips to connect it directly to the battery, so you can keep your lighter socket open for cell phone chargers or other accessories.

The Sunforce solar car charger is available from Amazon for $34.95.

This is a remote control that you can charge by turning a small hand crank — thus eliminating the need for batteries. You can control six different devices with the remote, including your television, DVD player, VCR, cable, satellite, and an auxiliary module. The wind-up generator requires only 30 revolutions for a full charge, which will last seven days. It’s priced at $24.99. Available from Smart Home.

This device is a night vision scope, but it doesn’t require any batteries. Instead, it’s has a lever-activated power supply, so you can generate your own power ad hoc. You’ll can see in the night without fear of an energy failture. It is priced around $200. See Camping Station or other vendors.
