Choosing green portable power chargers and extenders is the ecofriendlier alternative to tapping into the wall outlet to recharge gadgets. What makes these gadgets green? Some use solar or wind power to recharge your gadgets. For instance, the Iqua SUN solar Bluetooth headset recharges itself when exposed to daylight, and the HY Mini wind-powered charger can be strapped to your arm or bicycle to recharge your mobile phone, digital camera, or other portable gadget.
Human-powered chargers that convert your elbow grease or movement are also examples of green chargers. Two products from Freeplay (www. freeplayenergy.com) are the Freecharge Weza foot-powered portable generator, and the multifaceted Companion, a radio, flashlight, and cellphone charger all in one. The Companion has a solar panel and a hand crank to charge both it and your other gadgets. See Chapter 12 to find out more about greener chargers.
Buying rechargeable batteries (a topic I cover in Chapter 3) for your home's remote controls and other battery-operated gizmos is friendlier to the environment than continually buying and throwing away single-use batteries.
