It seems more and more gadgets, although they may have a wall wart, are ultimately USB-chargeable. Replace a normal AC wall socket with the USB Outlet Quattro from CurrentWerks, and you’ll be able to charge up to four USB devices at once without using those wall warts. With the Quattro, you have four standard USB ports in a single wall outlet. The Quattro accepts 90-132VAC 50/60Hz 0.7A current and outputs 22 Watts 5VDC 4.4A (2.1A maximum per port). CurrentWerks says the Quattro has been tested to UL standards, fits all standard single gang electrical boxes, and draws no vampire power. It’s available in white, ivory, and light almond for $39.98; faceplate is included.
