On the other hand, the power it loses turns into heat. The heat often is a bad thing. You want to look for inverter with efficiency higher than 80%

3. Fault Protection

OLP (Over load protection), if the inverter output too much power, in order to protect itelf and car battery, it will shut down until the overload condition is removed.

LVP (Low Voltage Protection), when the battery voltage is too low,  in order to protect the system. the inverter will shut off.

OVP (Over Voltage Protection),  the inverter input voltage is too high, inverter will turn off to protect itself and downstream devices.

TSD (Thermal ShutDown),  as said, the heat is often a bad thing for inverter. When the inverter gets too hot, it will shut itself off for good reason.
