    Works fine however the connection cord is too short and the off/on button is very sensitive. I was using with a Bluetooth stereo connection in the car and every time I moved my coffee cup it would disconnect the device.

    I’ve been caught on the road one too many times with a nearly dead laptop battery. This inverter is great. Easily fits in the center console of my truck and doesn’t take up much space. Plug and play!

    Overpriced for how long it last. My has started to make excess noise and seems to already be dying. The supplied wiring is junk.eq

    I bought this to run a laptop that draws around 160W. While running the laptop, starting the vehicle makes the voltage drop (obviously) and the inverter beeps continuously (even after the vehicle is running). If you disconnect whatever you have plugged in (or turn the inverter off) before starting the vehicle, it avoids this. It would be nice to have a "self-healing" feature. I plan to buy the remote for this so I can tuck it away behind the dash in my truck.

    This power inverter is exactly what we needed for our utility battery. It has USB ports but nowhere to plug in another device like a small heater when the power goes out.
