Whether you're at home or in the office, Tripp Lite's U280-010-ST 10-Port USB Charger provides plenty of ports and power to keep all 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 ten tablets, cell phones, laptops and other devices at the same time. It doesn't require a computer, so you can take it anywhere AC power is available. To charge your USB devices, simply plug the included external dual-voltage (100V?240V) power supply into any NEMA 5-15R outlet, and connect your devices to the available USB ports. The charger protects against overheating, overcurrent and overcharging-in fact, it stops charging as soon as your devices' batteries are at full capacity. A front LED indicates the unit is turned on and receiving AC power. The U280-010-ST delivers up to 5V, 2.4A to each port, which is perfect for charging even battery-intensive devices like the Apple iPad . At maximum capacity, this charger delivers up to 5V, 2A per port to all ten ports simultaneously. Plus, removable brackets on top of the charger allow it to also act as storage, providing space to neatly organize devices while they charge. You can adjust the brackets to accommodate the number and size of the devices being charged.
