Can I Use Someone Else's Electric Car Charger?

No, but it depends on the situation. Here are the relevant details: The main factors that cause damage to batteries when using incompatible electric vehicle chargers are current and voltage issues. In theory, electric vehicle chargers are not universally compatible, similar to mobile phone chargers, primarily depending on whether the voltage and current match. Generally, chargers from the same brand are more likely to be compatible, but it is still necessary to check if the voltage and current match before use. Many users assume that as long as the charger can be plugged in and the light turns on, it is compatible. However, this can easily damage the battery. As long as the voltage and current between the electric vehicle charger and the battery match, charging is possible. Additionally, high-end chargers like Gaobiao and Haoyichong electric vehicle chargers are designed with new protective features, such as constant current charging and constant voltage charging.
I've used my friend's electric car charger a few times, and it felt okay but requires caution. First, check if the interfaces match—standard home AC chargers like Type 2 or GB/T connectors are generally compatible, and they should charge normally when plugged in. However, don’t overlook safety details: if the cable is aged or damaged, it can easily short-circuit and catch fire, especially in rainy weather. Public charging stations are quite common now; just pay via an app, which is much more convenient. For DC fast charging, proprietary systems like Tesla’s may not be compatible with other cars. Occasional borrowing is fine, but don’t make it a habit to avoid inconveniencing others or exposing private charging patterns. The battery lifespan of an EV is also crucial; an unsuitable charger may cause overheating and damage. It’s best to carry a portable charger for emergencies—it’s much more reliable.
