It's generally greed that having a Level 2 charging station at home is the most convenient and cost effective way to charge your electric vehicle, but before buying your EV Charger, you should consider a few points:

- Type of charge port on your EV (NACS or J1772)
One of the first things to consider when looking to purchase an EV Charger is the kind of charge port that your EV has, either SAE J1772 or NACS.
Emporia offers Level 2 EV chargers with the SAE J1772 connector, and an adapter is required if you wish to charge a Tesla/NACS vehicle and from March 31st 2024 on, the NACS option along side the current J1772 version.

- Type of installation (NEMA plug or Hardwire)
Another important thing to consider is the kind of installation you will do. Emporia offers Level 2 EV chargers ready to be plugged in the 14-50P NEMA, or ready to be hardwired to a dedicated dual-pole breaker.

- Charger location

Another aspect to consider is where you wish to install your EV Charger. This will help your electrician plan for the wire length needed to run from your electrical panel (breakers) to the EV Charger itself.

- Vehicle's max charge rate
In order to know what charge rate your EV charger should supply, you must first know what the max level 2 charge rate your electric vehicle is. If your EV can only charge at a max of 32A, you probably don't need to consider hardwiring your unit to get up to 48A. The Emporia EV Charger can provide any amperage between 6A and 48A as needed.

- Existing electrical system and panel requirements
EV Chargers can consume vast quantities of power when charging your vehicle (up to tens of thousands of watts) so it's important to make sure your existing electrical system can safely provide that much power. Many customers will run into a situation where their existing panel (or electrical supply) might be too small for a level 2 EV Charger to be installed as-is. It's important to consult with a professional electrician when planning to install an EV charger as they'll be best suited to help determine if your existing electrical supply is too small for an EV Charger installation. Emporia has a product feature suit called "Load Management" which allows our chargers to operate in situations where the existing supply would otherwise be undersized for installing a traditional Level 2 EV charger: See here for more on our Load Management EV Charger.
