Tethered vs Untethered EV Chargers

If you drive a Skywell BE11, our high-range electric SUV with advanced battery and charging capability, understanding the difference between a tethered and untethered charger is essential when planning your home EV charging setup.

Whether you prefer the convenience of a permanently attached cable or the flexibility of using your own charging cable, this guide will help you choose the right option for your home charging and maximise your BE11 ownership experience.

What Are Tethered and Untethered EV Chargers?

When you are considering installing a charger for your electric vehicle, the key difference between a tethered EV charger and an untethered EV charger comes down to the charging cable:

• Tethered chargers come with the charging cable fixed to the unit, so the cable is always attached and ready to use.
• Untethered chargers do not have a permanently attached cable; you use your own charging cable and plug it into both the charger and your BE11.

Both types are designed to deliver reliable EV charging to your electric car, they just do it in slightly different ways.

How Charging Your Electric Car Works (Regardless of Type)

Whether your EV charger is tethered or untethered, the basic task is the same: deliver electric power from your home electricity supply to your Skywell BE11’s battery. When you plug in overnight, your BE11 can easily regain range, ready for your next drive, from daily commuting to weekend adventure, typically via a 7 kW home charging point.

In the UK, most modern home chargers and charging cables use the Type 2 connector as the standard for AC charging, compatible with vehicles like the BE11.

Tethered EV Charger

A tethered EV charger has the charging cable permanently attached to the charging unit. This setup is similar to how a fuel pump works, the cable is always there, secured and ready to charge your vehicle.

Advantages of a Tethered Charger

• Instant usability – simply take the cable from the tethered unit and plug it into your Skywell BE11’s charging port.
• No separate cable to buy – the charging cable comes with the charger, so there’s no need to purchase a charging cable separately.
• Less handling – no need to carry cables from your boot to the charger; ideal for everyday home charging.
• Security – the permanently attached cable is less likely to be lost or stolen.

Disadvantages of Tethered Chargers

• Extra cost upfront – because a cable is included, tethered chargers usually cost more initially than untethered units.
• Fixed cable length – the cable is permanently attached, so you’re limited to the length the charger comes with.
• Less future flexibility – if you change home layout or vehicles in the future, you can’t easily swap the cable without replacing the charger.

Untethered EV Chargers

An untethered EV charger doesn’t have a built-in cable. Instead, it features a socketed charging unit, and you provide and plug in the cable. This allows you to choose cable lengths and types that suit your home or travel habits.

Advantages of Untethered Chargers

• Lower initial cost – the unit itself is often cheaper because no cable is included, which can reduce the overall cost of your home EV chargers.
• Flexible cable choice – you can select the exact length and connector type you want (Type 2 is standard for UK vehicles like the BE11), making it easier to adapt if you upgrade or change EVs in the future.
• Compact installation – untethered units are generally smaller and tidier on the wall when the cable isn’t attached.

Disadvantages of Untethered Chargers

• Requires you to handle the cable for every charge – you need to get out your cable from your garage or boot storage, attach it to the charger, then to your BE11.
• You need a quality cable – while the charger may cost less, you may need to buy an appropriate charging cable, typically a Type 2 charging cable, which can offset some savings, although the BE11 comes with a cable as standard.
• Manage cable storage – you’ll need a safe, weather-protected place to store your cable when not in use.

Tethered or Untethered, Which Should You Choose for Your BE11?

There’s no one-size-fits-all answer; it depends on how you use your Skywell BE11 and what matters most in your daily home charging routine:

Factor	Tethered EV Charger	Untethered EV Charger
Convenience	⭐⭐⭐⭐	⭐⭐⭐
Flexibility	⭐⭐⭐	⭐⭐⭐⭐
Upfront cost	Higher due to cable cost	Lower for the basic unit
Cable management	Built-in	Requires storage
Future proofing	Less flexible	Can change the cable

 

If you prioritise everyday simplicity, then a tethered unit may suit your BE11 best. If you prefer flexibility and future adaptability, for example, you may use multiple EVs or want to tailor cable lengths to reach multiple vehicles, then an untethered home charger could be the better choice.

Both systems will provide reliable home charging for your BE11’s battery, so the “best” charger is ultimately the one that fits your home, budget, and lifestyle.

Think About Your Cable Needs

Whether tethered or untethered, a quality Type 2 charging cable can make a meaningful difference in ease of use and charging reliability, especially if you choose the untethered route. You might also consider having an extra cable for public charging points when you’re on the go.
