The term "granny charger" is colloquially used to refer to a standard electric vehicle (EV) charging cable that typically comes with the vehicle. It is designed to plug into a standard household electrical outlet, usually a 120-volt outlet in North America or a 230-volt outlet in Europe and other regions.

Here are some key characteristics of a granny charger:

1. Slow Charging Speed: Granny chargers are generally slow compared to dedicated EV charging stations. They typically provide a charging rate of around 2-5 miles of range per hour, depending on the vehicle and the electrical system.

2. Portability: These chargers are portable and can be carried in the vehicle, making them convenient for use at locations where dedicated charging stations are not available.

3. Standard Plug: They usually come with a standard three-pin plug (Type G in the UK, Type A/B in North America, etc.) that can be inserted into a regular household socket.

4. Safety Features: Despite being slower, granny chargers are equipped with safety features such as thermal sensors and ground fault protection to ensure safe charging.

5. Emergency Use: They are often used as a backup or emergency charging option when other charging options are not available.

While granny chargers are convenient for occasional use, they are not ideal for regular charging due to their slow speed and the potential strain they can put on household electrical systems. For faster charging, EV owners typically use dedicated home charging stations or public charging networks.
