The PV200CUSB 200 W PowerVerter (R) ultra-compact car inverter provides 200 W of portable power for charging and operating multiple devices in your car, truck, boat or RV. It converts 12 V DC power into standard 120 V AC power to run a wide variety of electronics, such as smartphones, laptops, tablets, GPS units, game systems, portable TVs, DVD players and MP3 players, as well as low-power lights, camping accessories, battery rechargers for small battery-operated power tools and mobile office equipment. And for extra convenience, it fits snugly into your vehicle's cup holder to help prevent it from tipping over or sliding around during travel. The PV200CUSB features 2 AC outlets, a 2.1 A USB port and a 1.0 A USB port. Just plug the DC input jack with convenient 3-ft cord into the 12 V cigarette lighter socket in your vehicle, press the on/off switch, and the unit is ready to operate. Easy-to-read illuminated switch lets you know the inverter is receiving power from the battery. To prevent you from running down your car battery, the PV200CUSB turns off automatically when the input voltage falls to 10 V. Likewise, the unit will also shut down if it gets too hot (for instance, because your connected devices exceed 200 W). A built-in ventilation fan keeps the interior cool during extended use. The durable plastic housing is engineered to withstand the rigors of road trips, campouts, business trips, and family vacations. No maintenance is required.
