Got one of these for the office desk - powers the PC and charges my phone and BT headphones. Works well and looks good. They're doing £5 off just now - makes them a good deal (They were £18 when I bought mine).
Good quality Mains Extension Lead, With 4 USB Ports (4.6A) + 3 Way Outlets and Surge Protector Power Extension Plug, Intelligent Charging with 5.9ft Power Cord
