Battery Charging Systems & External Power Adapters


Energy-Efficient Chargers Are Better for the Environment

Now that you know your electronics contribute to a quarter of your home's energy use, did you know that the battery chargers and external power adapters that come with many gadgets are energy wasters? In fact, conventional battery chargers can draw as much as five to 20 times more energy than is actually stored in the battery, even when they are not charging it. And external power adapters may lose 10% to 70% of the energy they consume because much of that energy is converted to heat.

ENERGY STAR® qualified battery chargers and external power adapters use up to 35% less energy than conventional models. Plus, switching to energy efficient battery charging systems will prevent the release of more than one million tons of greenhouse gas emissions in the U.S.

Go one step further and plug your battery chargers and external power adapters into an advanced power strip to maximize your energy savings.
