This neat little device solves that common dilemma of the modern motorist: charging both one's iPpod and sat nav when most cars have but one fag-lighter socket. Well, it'll power any two items that'll fit the socket - phone charger, laptop plug, bluetooth phone speaker (might be a tight fit beyond the socket), whatever. It's suitably robust, but not Soviet, with no annoying bits to catch finger nails on. There's a small red LED to let you know when power's running through it. Minimal packaging and it arrived on time. From tip to top it's not quite 4 inches/100mm long, about 65mm by 35mm in plan.
