The 24 amp electric car charger is a sought-after but uncommon device. It can supply your automobile with up to 5.8 kW and is powered by a 240 volt mains supply.

If you’re charging aт EV battery that holds 75kW of electricity, you’ll be able to fully charge it in 12 hours using this charger.

There are a variety of home charging stations for electric cars. These vary from Level-1, which can charge your car at different speeds depending on its battery power and need. All the way up through 40 Amp high power (HP) EV chargers that take about four hours to fill up an EV with a 75 kW battery.

What kind of 24-amp EV charger do you need for your electric car? There are many types and they all have their pros.

Charging stations 24-amp and up

24A portable chargers

A portable charge might be the right choice if traveling often, but a plug-in type will offer more stability while plugged into an outlet at home or work (and it doesn’t require any installation). 

A 24-amp portable EV charger can charge your electric car much faster than Level-1 chargers. The compact size of the charger will allow you to take it with you when you go places. You can also keep it in your car or in your house. It doesn’t take up a lot of space.

24-amp chargers, which are equivalent to 5 kilowatts, can charge a fully charged, medium-capacity car battery in just 13 hours. In just one hour, the 24 amp chargers can charge an electric car for approximately 25 miles. This charger is 3.5x more efficient than Level-1 chargers. They can be connected to 240 volts. The 24A units are compatible with NEMA 6-30, 10-30 or 14-30 outlets. They have a breaker capability of 30 amps or more. These devices are not often hardwired.

High power chargers compatible with 24A

There are charging stations with a range of 24 amps and higher that can handle the required power. Don’t worry, they’re also compatible with electric cars with different capacity limitations. Their main benefit is the potential for extra power if you upgrade to an electric vehicle in the future and need 40 amps rather than 24 amps.

We have a few chargers for you! The NEMA 14-50 is a U.S. standard that can be found in residential properties, and it’s great if your device won’t draw more than 40 amps. Check out the full review of the NEMA 14-50 models here.

The following is a list of the best hardware chargers. We’ve compiled it from experienced customers’ purchases to provide you with as accurate a picture as possible!

Hardware chargers compatible with 24 amp

Hardwired  types of devices are considered safe compared to plug-in models, which may not last as long and may not provide reliable performance in the future. You will have to do more complex steps to dismantle the unit if something goes wrong with it (e.g., hire an electrician who will charge extra).

Hardware models have a maximum power rating of more than 24 amps, but they adapt perfectly thanks to OCPP to your electric car, even if the EV has an incoming power limit. If you allow electric cars to be used in the future, it makes sense to invest in more powerful devices, such as 40-amp units.

Why is Level 2 EV charger better than Level 1? Level 2 uses 240-volt and provides less waiting time for charging.

When choosing a 24-amp EV charger, you should pay attention to the following criteria

Amperage: The amperage of the charger is important to consider because it will determine how quickly your vehicle can charge.

Cable length: The cable length is also important to consider because it will determine how far away from the charging station you can park your vehicle.

Socket: The socket type is also important to consider because it will determine compatibility with your vehicle.

Waterproof: The waterproofness of the charger is also important to consider because it will protect against weather damage.

Weight: The weight of the charger is also important to consider because it will affect portability.

Warranty: The warranty is also important to consider because it will determine the length of time the charger is covered.

Certificate (UL): The certificate is also important to consider because it will verify that the charger meets safety standards.

So what’s the advantage of plug-in EV chargers over hardwired EV chargers?

Socket. Plug-in chargers are more versatile, as they can be used with any EV, regardless of make or model. Hardwired chargers, on the other hand, are specific to a certain make or model of EV and cannot be used with other vehicles.

Another advantage of plug-in chargers is that they are portable. If you need to move your EV to a different location, you can simply unplug the charger and take it with you. Hardwired chargers, on the other hand, are not as easily portable and must be installed by a professional electrician.

Finally, plug-in chargers are typically cheaper than hardwired chargers.

Why high power EV charger for home is a good investment?

If you’re considering purchasing an electric vehicle (EV), you may be wondering if it’s worth investing in a high-power EV charger for your home. Here are a few reasons why a high-power charger can be a good investment:

1. You’ll be able to charge your EV faster.

2. You won’t have to worry about finding public charging stations.

3. You’ll be able to take advantage of lower electricity rates, if your utility offers them.

4. You’ll have peace of mind knowing that you can always charge your EV at home, even if there’s an emergency or power outage.

5. High-power chargers can add value to your home if you ever sell it.

If you’re thinking about purchasing an EV, a high-power charger, like a 40-amp charger, is definitely worth considering. It’s a worthwhile investment that will make owning and driving an EV more convenient and enjoyable than a 24-amp charger.
