Juice box 40 vs. 48: Which is Better?

juicebox-40-vs-48

The main difference between the Juice Box 40 and 48 is the charging speed. From the name, the Juice Box 48 has a 48-amp ESVE, a higher maximum charging power output than the Juice Box 40, which has a 40-amp ESVE. It’s also important to note that the charging speed also depends on the vehicle.

My wife and I both have Mach E standard and extended range. As you’d surmise, I bought the Juice box 48 while she got the 40. I’ve run a series of tests to see if the difference in both chargers is significant, and it is. As you’d expect, the 48 charges a lot faster than the 40. Other than that, there wasn’t much difference between the two chargers. So, the driving force should ultimately be the kind of car you have.

In this article, we will delve into the charging speeds offered by juice boxes 40 and 48, the differences between these charging stations, and how their varying charging speeds can impact your EV driving experience.

Installation and compatibility

Installation prerequisite

The JuiceBox requires either a direct electrical connection to your home’s wiring or a NEMA 14-50 outlet, which is a type of electrical outlet.

The circuit breaker that the JuiceBox is connected to must be rated for at least 125% of the device’s continuous load, or the maximum amount of power it will draw continuously. This ensures that the circuit breaker will trip if the JuiceBox draws too much power, which helps prevent electrical damage or fire hazards.

Compatibility of The Juice Boxes 40 and 48 with Different Electrical Systems and Residential Setups

The compatibility of the Juice Box 40 and 48 charging stations with different electrical systems and residential setups depends on the voltage and wiring configuration of the electrical infrastructure available at your location. Let’s break down the compatibility considerations:

Build quality and durability

  • The JuiceBox uses a weather-proof, dust-tight polycarbonate casing and robust cables and plugs, making it durable and reliable in all conditions.
  • Efficient heat dissipation (a temperature rating of -40°C to +60°C) is crucial for the longevity of the juice box. The juice boxes are designed with built-in cooling mechanisms to regulate the temperature during charging. This helps prevent overheating and ensures consistent performance over time.

Warranty and customer support

The warranty typically covers the charging station, its components, and its internal electronics for a period of 3 years. However, it does not cover mishandling or improper installation. It’s important to carefully review the warranty terms to understand what’s included and any specific conditions or limitations.

Also, the JuiceBox 40 and 48 have been tested and certified by the UL, which means that they have met the UL’s rigorous safety standards.

Juice box manufacturers often provide technical support to help users with installation, setup, and troubleshooting.

Although, for US customers, you can contact them 24/7 at (844) 584-2329.

Energy efficiency

The JuiceBox 40 and 48 both come with a variety of energy-saving features. One such feature is

  • Smart Charging allows the JuiceBox to automatically optimize charging based on utility rates, weather, and battery capacity. This can help reduce energy costs and maximize efficiency.
  • The “Schedule” feature allows you to set specific times for charging so you can take advantage of off-peak electricity rates.
  • Remote monitoring allows you to control charging anywhere from your mobile app.

Load management capabilities

Both the JuiceBox 40 and 48 support load management, which allows you to set a maximum amount of power that can be drawn from your electrical panel at any given time.

For juice boxes 40 and 48,

  • Balance at the circuit level means that the total power drawn from all of the devices connected to a circuit should not exceed the circuit’s rated capacity.
  • Only balance stations with the same specifications mean that the load management system should only be used with devices that have the same specifications, such as the same amperage and voltage rating.

Please note when setting up your load sharing that the overcurrent device (circuit breaker) cannot exceed the rated amount of a normal JuiceBox installation.

In summary

It is important to note that whether the features and capabilities of the Juice Box 48 justify the price difference compared to the Juice Box 40 depends on your specific circumstances and priorities. If faster charging speeds align with your needs and you have an EV capable of taking advantage of the higher power output, the Juice Box 48’s higher price could indeed be justified. On the other hand, if faster charging is less of a priority, the Juice Box 40 might offer a more cost-effective option while still providing valuable smart features, convenience, and fast charging.
