We were surprised to find the app to be less intuitive to use. Since then, the company redesigned its app, so we gave it another go. When we first tested these charging units in 2022, we liked the JuiceBox best. Other home EV chargers we tested: JuiceBox 40 EV Charger We also find the Wall Connector's sleek shape and glasslike clear top layer the most visually appealing. Surprisingly, although the Wall Connector is capable of nearly the highest output of our group (48 amps or 11.5 kilowatts), it has the thinnest, most flexible cables. The setup process for the Wall Connector is easy you simply scan the QR code on the side of the unit to connect to Wi-Fi and then set the output limit through a web-based interface. Also, with the Tesla plug unit, you can choose to allow specific Tesla vehicles to charge while blocking others. For instance, it can network multiple units together to share a single circuit where the combined output will never exceed a set threshold. Dave VanderWerp | Car and DriverĪlthough the lack of electricity tracking is probably the biggest drawback, Tesla's home-charging unit has a few advanced features that none of the other units have. Tesla’s Wall Connector is a cinch to set up. Best EV Charger on a Budget: Emporia EV Charger We also appreciate the simplicity of the built-in notch at the top of the unit to wrap the cord around and that the plug latches onto its dock in the center many other units require mounting a second cord-management device. The ChargePoint app has the most nuanced cost tracking, allowing us to select from among dozens of possible rate plans from our local utility to pinpoint the actual cost of charging down to the penny, even when on a variable rate. ![]() Furthermore, it offers the ability to schedule charging times to take advantage of variable-cost electricity during off-peak hours (most EVs also allow this to be configured in their settings menu). ![]() We found the app to be very user-friendly, with the best displays for charge-rate graphs, and it also shows the total charge time and total energy output during each charge. You can add your vehicle in the app, which tailors the percentage of the battery replenished and number of EPA miles added to your specific vehicle. Its Home Flex unit tested here integrates into the same app used to connect to the company's public units. Output capability: 50/48/40/32/24/16 amps (12.0/11.5/9.6/7.7/5.8/3.8 kW)ĬhargePoint is one of the largest providers of public charging, with thousands of units nationwide.Lower output settings require hardwire installation.Lesser outdoor rating than some of the others.The appliance power ratings suggested are indicative only. Here’s our guide to the current ratings of commonly-used domestic appliances. Alternating current (AC) is used to supply things like houses, buildings and mains connected appliances. However, in alternating current (AC) the electric current changes direction at 50 times per second (50 Hz or hertz) in the UK supply.Īn example of direct current would be a battery powered torch. For direct current (DC) the electric current flows only in one direction. The labels ‘AC’ and ‘DC’ are used to describe the types of current flow in a circuit. In terms of the hosepipe example, this would refer to the amount of water being released. The higher the wattage is, the more power and output from the appliance. ![]() WattsĪmps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow. Volts are the measurement used to determine how much force is needed to cause the electric current to flow. The more water flowing through the hosepipe, the stronger the current is. You should think of electric current as the flow of water through a hosepipe. ![]() Amps x Volts = WattsĪmps measure the flow of electricity as an electric current. Amps to Watts FormulaĪlternatively to using the calculator, here are some basic equations which allow you to calculate the missing information on your own. Find out how to convert Watts to Amps here or how to calculate Ohm's Law here.
