Level 1 Charger
This type of charger usually comes with the car and is free. However, they’re not top of the range, and many drivers elect to buy an additional one.
A level 1 charger is best used by drivers who don’t take their car for long distances and are patient with the charging as it can take a long time.
As for installation, they only require a standard and safe electrical outlet to be connected to.
The units themselves range in price from free to around $450.
