The Wagan 4-Way 12 V Automotive Socket Extender lets you power up to four electronic items at once. Simply plug it into your vehicle's 12V DC socket to quickly expand from one DC socket to four. One of the four sockets can be used with a cigarette lighter (lighter not included). This extender is ideal for powering your laptop, mobile phone, CD player, satellite radio, radar detector, and more. It also includes a built-in fuse protector to protect your vehicle from damage. Mounting hardware is included (screws, mount, and double-sided tape) to help you position the unit securely on the dashboard inside your vehicle. The 34-inch cord length gives you the flexibility to place this extender right where you need it.
