I've been using this multi-use car charger in our older camper van for over a year. With two cigarette lighter ports and two USB ports, it is by far the best auto accessory for us power users and road warriors. It comes configured to plug into an unused cigarette lighter receptacle, but can also be installed with either double sided tape (included) or using removable tabs and screws (included) to permanently mount inside a vehicle. I wired ours directly to the Eurovan's wiring to replace the single cigarette lighter port near the driver's seat. Very heavy duty in construction, it's built like a tank. No heat, no troubles. It's made a great addition to the vehicle, which we use frequently during the summer and winter for multi-day trips. Now we can routinely power up our cell phones, window-mounted TomTom GPS and a laptop (with a 100W max inverter). The USB ports have worked great to power everything we've hooked up to it: iPod, cell phones, Bluetooth kit. While most chargers and inverters I've seen max out at 10 or 15 amps, this one handles 20 amps, which is enough for all four devices to charge at the same time. The total power we pull from this charger when simultaneously charging is maybe 10 amps, but it's great to have the option of using a bigger inverter to pull additional power. This unit also sports a removable 20A fuse on the back panel should anything go awry. The instruction sheet is clear and shows how to wire the unit to your vehicle without too much fuss. At under $20, an awesome deal.
