The PS1916D1U 16-Outlet 1U Rack-Mount AC Charger Power Strip provides high-speed charging for up to 16 mobile devices simultaneously, such as notebooks, netbooks, tablets and other battery-intensive electronics that use a NEMA 5-15P plug. This power strip features 16 built-in NEMA 5-15R AC outlets attached to convenient dongles that easily accommodate large transformer plugs. It's compatible with all devices that charge via standard AC outlets (such as Chromebooks, MacBook Airs and Ultrabooks) or user-supplied USB power adapters (such as smartphones, iPads, Kindles, Kindle Fires and Surface models).The all-steel PS1916D1U mounts into 1U of two- or four-post rack space using the included hardware. The NEMA 5-15P input plug is attached to a 15-foot power cord long enough to reach a PDU or AC wall outlet. A 15-amp circuit breaker protects against overloads and short circuits. A transparent cover guards the lighted on/off switch from accidental shutdowns.
