Frequently Asked Questions

Fast charging can be achieved by purchasing a 240 volt level 2 EV charger.   This will provide for a 32 amp charging current (7.4kW power delivery per hour) or 40 amp charging current (9.6 kW power delivery per hour), which can reduce charge times from 10-12 hours down to 3-4 hours depending on the size of your battery.

For rapid charging at selected public charging stations, the cable will always be tethered to the charge point, looking a bit like a traditional gas pump. Your car will be fitted with either a separate socket or a special dual socket for taking this type of charge, which is a DC current.

EV Chargers provide different charging times depending on the type of charger and your plug at home. Level 1 chargers are generally 3 pin plug chargers with much slower charge times. Level 2 chargers are generally 4 pin plug chargers with more power so will charge more quickly.

Yes a Level 2 charger is worth the extra premium (generally $150-$200). This is because it provides a much faster charge time for your vehicle and can reduce charge times by around 50% depending on the type of car you have.

Over the years, the U.S. market has had many different types of 240V plugs and there is no standard.  There are some that are more common than others and that are generally recommended.  We offer different plugs for different receptacles:

NEMA 14-30 (30A plug) – This is most commonly used for electric clothes dryers.  It’s installed onto a dedicated 30A circuit to match the rating of the plug. 

NEMA 14-50 (50A plug). This is commonly used for electric ovens and is often found in RV parks and campgrounds. It’s installed onto a dedicated 50A circuit to match the rating of the plug.

NEMA 6-50 (50A plug). This is common for welders or plasma cutters. It’s installed onto a dedicated 50A circuit to match the rating of the plug.

Please go to our selector tool. https://evchargersusa.comev-charger-selector-tool/    We lay out the best charging options based on your vehicle battery size and acceptance.

The first type of plug, called a Type 1, is used by most cars and trucks made in North America. This is also known as an SAE J1772 connector. It looks like this:

The second type of plug, known as a Type 2 or Mennekes connector, is used by many Asian brands such as Nissan Leaf and Mitsubishi Outlander PHEV.

Lastly there’s the Tesla Supercharger which allows for high-speed charging – delivering up to 120 kW from a single car charger with no reduction in battery performance or capacity over time.

Most early production EV vehicles were fitted with a 3.6KW onboard charger as standard, which best matched a 16 amp cable.  More recent models have 7KW onboard charge capability which require a 32amp cable.  Please refer to our EV Selector tool.  https://evchargersusa.comev-charger-selector-tool/  We match the KW battery charge acceptance rate (kW) with your car to provide the right charger.

Yes, all US electric and plug-in hybrid cars use a Type 1 connector. This is sometimes referred to as an SAE J1772. The Type 1 (SAE JA772) plugs support Level 1 and Level 2 charging standards. Using our EV chargers you will be able to charge all Electric cars and Plug Hybrids including Ford, Tesla, Nissan and Mercedes.

Yes.  A 240 volt charger can typically provide a 32 amp or 40 max charging current.   This equates to a 9.6kW max power delivery per hour (or 240V x 40A = 9,600 watts or 9.6 kW).

You do not.  We did that for so you can pick the best charger using our ev charger selector tool https://evchargersusa.comev-charger-selector-tool/

Yes.  The EV charger will not charge faster than the maximum charging capacity/on-board battery acceptance charge rate of the car.   The benefit of this is futureproofing your charging with a more powerful charger for your next car to save purchasing another charger.  The EV charger controls the charge and will only take in the power it is made to accept.

You need to check the on-board battery charge capability of your car and the source of the power you’re charging from. You can only charge at the battery charge rate that your car can take (kW acceptance rate) and at the amp rate the power source is providing.  For example,  Nissan Leaf models have a 3.3 (kW) acceptance rate so even though you have a 32 amp cable, which pushes out 7.4kW, the battery can only accept 3.3kW.
