Such a simple idea; such a useful product. Satechi’s Compact USB Surge Protector is a diminutive 1.4-inch by 2-inch by 1.25-inch-deep three-prong plug that converts a single AC outlet into dual outlets — one for a two-or three-prong AC plug, the other for a USB charging plug. Both get surge protection. OK, this isn’t cutting edge tech, but how nice to be able to charge two electronic devices simultaneously while freeing up an AC power outlet or a USB port on your laptop. The lime green face helps distinguish this adaptor from similar-looking ones without surge protection. An LED indicator lights up green to show the surge protector is working. The 1-amp output is fine for charging smart phones and 7-inch tablets, but may or may not be able to handle larger tablets. My iPad charged OK, but I’m hoping Satechi’s next model has a 2-amp output to guarantee success. Still, this is cheap, small and welcome — especially in outlet-challenged rooms.
