Need a specific power adapter for your device? This is an AC to AC adapter by Ablegrid that outputs 16 volts at 1 amp (1000mA), with a common 5.5mm x 2.1mm barrel plug. It's got a standard US plug, so it works in any wall outlet here. The adapter is brand new, unused, in its original packaging (might be simple packaging, not retail). It's perfect for powering various electronics that require 16V AC input - maybe certain routers, monitors, audio equipment, or other gadgets. Always check your device's voltage and current requirements before using! The UPC is 753038965215, and there's a California Prop 65 warning (which many electronics have, so don't panic). If you've lost the original charger for something or need a spare, this could be the right replacement. Just match the voltage (16V), the plug size (5.5mm outer, 2.1mm inner), and make sure your device uses AC input, not DC. Keep one in your drawer of spare cables - you never know when you'll need it to revive an old piece of equipment or power something unusual.
