Electric Vehicle Charger Buyer's Guide

Why Buy an Electric Vehicle Charger?

Having an electric vehicle charger in your home is convenient, efficient and great for your wallet. And, like electric vehicles, they’re always getting smarter. EV Chargers like JuiceBox Pro 40 and ClipperCreek (now featuring JuiceNet software) offer advanced Wi-Fi control and smart grid features that automatically adjust to provide as much power as your EV is able to accept. No longer will you have to travel to the garage to check your charge; with JuiceNet technology, you can manage your charge rate and power consumption right from your smartphone or tablet. Stop and start charging remotely and see your charge data in real-time. Or, ask Amazon’s Alexa or Google Home to check it for you.

How to Choose an EV Charger.

Plug-In Models

The plug-in option is optimum for users who think they will need a portable charger. A certified electrician may need to install a dedicated breaker in your home's electrical panel, but besides that, the only installation required is for the wall mounting station. Once the wall mounting bracket is installed, you can slide the EV charger in and out easily, allowing you to use it at home or take it with you if needed.

Hard Wired Models

The hard wired option is optimal for users who have no need to move the charger. Select charger models are only available as a hard wired option so be sure to review you vehicle's specifications.


Get the Power you need.

Most customers will prefer the efficiency of a 32-40 Amp charging station, as they maximize the charging speed of their electric vehicle. Your electric vehicle will have an onboard charger that limits the speed in which your vehicle's batteries can be charged and due to their lower amperage will take longer to charge your vehicle. JuiceBox charging stations automatically adjust to provide only as much power as your electric vehicle is able to accept and charge up to 10x faster than onboard chargers.

Tesla Models

Tesla Model X and Model S have dual-onboard chargers which enable the batteries to be charged at a faster rate. These Tesla models can fully utilize a 75 amp charging rate (available with the JuiceBox Pro 75) whereas other vehicles would not charge any faster due to the limits of their onboard charger. Be sure to check the specifications of your electric vehicle to determine the limits of the onboard charger and the maximum charging speeds.

Make Your EV Charger Smart.

With JuiceBox chargers, connecting your EV charging station to Wi-Fi can enable you to view real-time electricity use and set charging schedules to ensure your electric vehicle is always charged when you need it. If you are on a Time-of-Use rate plan, the scheduling functionality can also help to lower your bill by charging at the lowest electricity rates.

Smart Home Connection.

You can connect eligible EV charging stations to smart home devices such as Amazon Echo or Google Home. With Alexa voice controls or Google Voice Assistant users can start, pause or resume charging with simple voice commands.

Charging Levels Explained.

 Level 2 Charger: More powerful than a Level 1 Charger, Level 2 chargers provide power at 220v or 240v. This level charges 10-25 miles in an hour and is ideal for frequent drivers who desire faster charge times. JuiceBox EV Chargers charge up to 10x faster than Level 1 chargers. 

Level 1 Charger: Connects to the on-board charger and standard household outlet (120v) using a plug. This level typically provides approximately 5 miles per hour charging. While the slowest form of charging, this type of charger is ideal for those who travel infrequently and have a quick commute.

Charge Time Table

This Charge Time Table shows approximately how much electric range a typical EV can recover for charging stations with different capacities. Level 1 charging stations use 120 V, while Level 2 charging stations use 240 V. Charging capacity is rated in kilowatts (kW), while the vehicle's battery pack is rated in kilowatt-hours (kWh).

Load Sharing

If you have more than one EV, you can set up two (or more) units to share one electrical circuit. For instance, you have only 40A capacity in your panel but have two vehicles charging simultaneously, you can program your units to never exceed 40A combined draw. If only one vehicle is charging, it gets the full 40A of current. When the second vehicle plugs in, the current gets shared 20A / 20A between the two. When one of the vehicles finishes charging, the remaining vehicle ramps back to 40A.
