How Do I Choose The Right Charger for me?
After purchasing your new electric vehicle the first thing you will likely want to be able to do is charge it at home. In order for you to be able to charge it up in a reasonable amount of time, this means you will need a level 2 charger. If your are using the Level 1 charger it will only add about 3-5 miles in one hour and will leave you without "fuel". With a level 2 charger you can get 30+ miles of range in one hour and keep you ready for the road.

Charging Level
Level 1 chargers only add 3-5 miles per hour
Level 2 (32A) chargers add around 20 miles per hour
Level 2 (48A) chargers add around 30 miles per hour
Cable Length
The two standard cable lengths are 12' and 18' but the industry now also offers 25'. Make sure to choose the length that will work for the spot you chose your EV charger to be installed.
Connector Type
In North America for residential home EV charging, there are two standard connector types. The J1772 (Type 1) connector is utilized for all electric vehicles other than Tesla's which use a proprietary connecter but include and adapter to the J1772 plugs.
The Cost of Installing a Charger
The total cost of an EV charger installation can range from $1450-$6000+ depending on the complexity of the installation.
If you are installing your EV charger in your attached garage near an existing electrical panel you can expect the low end of those figures. However if you need to upgrade your electrical service and run power to a detached garage you could end up with a much higher cost.
