Whether you're at home or in the office, Tripp Lite's U280-004-WS3C1 4-Port USB Charging Station provides enough ports and power to keep your devices at 100% capacity. No more peering behind furniture to find an available outlet or unplugging one device to charge another. You can charge up to four tablets, cell phones, laptops and other devices at the same time. The U280-004-WS3C1 doesn't require a computer, so you can take it anywhere AC power is available.
The U280-004-WS3C1 features three auto-sensing USB-A ports, each capable of delivering up to 5V, 2.4A, which is enough for charging cell phones, tablets and other mobile devices. Each USB-A port senses the connected device and automatically adjusts the required power level accordingly. A USB-C port supports power output up to 20V, 3A for charging more battery-intensive USB power delivery devices, such as a MacBook®, MacBook Pro® or Chromebook Pixel™.

To charge your USB devices, simply connect the detachable four-foot power cord's NEMA 1-15P plug to an AC power outlet, and connect your devices to the available USB ports. The unit protects against overheating, overcurrent and overcharging-in fact, it stops charging as soon as your devices' batteries are at full capacity
