Tethered vs Untethered EV Chargers: Which Is Best?

As an electric vehicle (EV) owner or potential owner, you’ll likely be exploring home charging solutions for added convenience. With a variety of options available, it’s important to understand the differences between tethered and untethered chargers to determine which one best suits your needs. At myenergi, we’re here to provide you with a comprehensive guide to make an informed decision on the ideal home EV charger for you.

Tethered vs. Untethered EV Chargers: The Key Difference

The primary distinction between a tethered EV charger and untethered EV charger lies in the charging cable. Tethered chargers feature a permanently attached cable, while untethered chargers offer a detachable one. For most people charging one modern EV at home, a tethered charger is the simpler choice, while an untethered charger gives more flexibility on cable length and connector type. Both types charge at the same speed

Is a tethered EV charger more expensive than untethered?

When weighing the costs of tethered and untethered EV chargers, consider that tethered chargers typically cost more upfront, as the cable is included in the price. Untethered chargers are initially cheaper, but you may need to purchase a charging cable separately, potentially minimising the price difference. However, the zappi is the same price regardless of being tethered or untethered making it the perfect solution for both uses.

Is a tethered EV charger more secure?

Tethered chargers are more secure than untethered chargers due to their permanently attached cable, preventing theft. Untethered chargers’ detachable cables are more susceptible to theft, but many models feature added security measures such as pin protection or cable locking. To keep the cable safe, it’s best to disconnect and store it out of sight when not in use.

What is a tethered EV charger?

A tethered EV charger has its charging cable permanently attached to the unit, so there’s no separate cable to connect. Simply unwind the cable from the charging unit and plug it into your vehicle’s charging port, much like using a petrol or diesel pump. The charging cable is included in the unit’s overall cost.

While the convenience is what sways most EV owners to buy a tethered charger, they do have limitations. The fixed cable length can restrict charging flexibility, and compatibility issues may arise if your vehicle requires a different connector type (Type 1 or Type 2).

What are the pros of a tethered EV charger?

Charging cable included in the unit’s price
Convenient charging process
Reduced risk of cable theft

What are the cons of a tethered EV charger?

Fixed cable length provided by the manufacturer, so the charger must be installed within reach of your car’s charging port
Restricted to either Type 1 or Type 2 charging connections so if you change your car in the future, you would need to ensure you still buy the same ‘type’ or purchase a new charger.

Tethered Vs Untethered

What is an untethered EV charger?

An untethered EV charger has a socket instead of a fixed cable, so you plug in your own charging cable each time you charge. You can use the cable that came with your EV, take it with you for public charging, or let guests charge their EVs at your home.

Despite their flexibility, untethered chargers are less convenient than tethered chargers, as you’ll need to connect and disconnect the cable each time you charge. However, they are more future-proof, allowing you to replace the cable if you need a longer one or a different connector type without purchasing a new charging unit.

Aesthetically, untethered chargers can also appear tidier, as the cable can be disconnected and stored out of sight when not in use.

What are the benefits of an untethered EV charger?

Swap the cable for a longer one or a different connector type without replacing the charger
Use the same cable at home and on most public chargers
Suits households with more than one EV
Tidier look on your wall when not in use

What are the drawbacks of an untethered EV charger?

You may need to buy a Mode 3 charging cable if your car didn’t come with one
You have to plug in and unplug the cable every time you charge
The cable needs storing somewhere dry and secure when not in use

Is a tethered or untethered EV charger better?

A tethered charger is better for most people charging one EV at home; choose untethered if you have more than one EV, need a longer cable or are likely to change car soon.

Both tethered and untethered chargers have their pros and cons, so carefully consider your specific needs and usage patterns before making a decision. Replacing a charger can be expensive, so gather as much information as possible to make an informed choice.

Tethered units are generally more convenient for home charging, while untethered units offer increased flexibility, with their detachable cables usable both at home and on public chargers.

Ultimately, the best charger for you depends on your individual preferences, requirements, and charging habits. Take the time to evaluate both options to find the ideal home EV charging solution for your lifestyle.
