The PD2000 power inverter allows you to use multiple AC devices in your vehicle simultaneously. It can handle 2000 watts continuously, and up to 4000 watt peaks. You get access to 4 AC outlets, and 2 2.4 amp USB outlets for fast charging cell phones, tablets, and other devices. The faceplate is detachable so you can monitor the voltage and turn on/off the power without accessing the inverter itself. There's even a downloadable app that allows you to pair the inverter with your phone to monitor and change settings.
