Re-activateAT&T announced that in May it will begin selling a replacement phone charger it claims will be more efficient than other cell-phone chargers sold today. Called the Zero, the charger automatically detects when a phone is not plugged into it, and cuts off the power supply from the wall socket to save energy—something few electronics chargers do.
Besides saving on energy consumption, the Zero charger features a "block and cable" connector that will fit many future phones from the carrier, which AT&T says will eventually lower landfill waste. Also green will be its packaging, which will be smaller and made entirely from recycled paper. No price has been announced, though AT&T says it will cost the same as existing replacement chargers.
