Is a 12V to 220V car inverter harmful to the vehicle?

[CeciliaMarie]

Damage certainly exists. Prolonged use will drain the battery, making the car unable to start, requiring a push start, which is dangerous. Furthermore, automatic transmission vehicles won't be able to start at all and will need a battery replacement. Therefore, avoid prolonged use of car inverters to prevent battery drainage. The vehicle itself won't be harmed, only the battery will suffer. Extension: Based on the description, it's identified as an inverter, which converts 12V or 24V voltage to 220V. 1. Oxygen concentrator: Determine the power of the oxygen concentrator. 2. Inverter: Based on this power, choose an inverter with double the margin online, preferably one with many purchases and good reviews. 3. Brand: The brand isn't very important; inverters are already quite mature.
