When you pick a home EV charger, one of the first choices is tethered or untethered. Neither is universally better — it comes down to convenience, tidiness, and future flexibility. Here’s a straight comparison.

The difference in one line

• Tethered: the charging cable is permanently attached to the unit.
• Untethered (socketed): the unit has a socket, and you plug in your own portable cable each time.

Tethered: pros and cons

Pros

• Convenience — the cable’s always there; just unwind and plug into the car.
• No fetching a cable from the boot each time.
• Slightly simpler day-to-day, especially in winter.

Cons

• A trailing cable to manage and store (most have a holster).
• The connector type is fixed — virtually all modern EVs use Type 2, so this rarely matters now, but it’s less flexible long-term.
• A fixed cable length — must reach your car’s port from the unit.
• If the cable is damaged, it’s a bigger fix.

Untethered: pros and cons

Pros

• Tidier — no permanent cable; just a neat unit on the wall.
• Future-proof — swap the cable for a different length or type, or replace it easily if damaged.
• Often a slightly cheaper unit (you buy the cable separately).
• Flexible if you change cars.

Cons

• You plug and unplug a cable each time and store it (usually in the boot).
• A separate cable to buy (and remember).
• Marginally less convenient in bad weather.

Which should you choose?

• Want maximum day-to-day convenience? → Tethered. Most homeowners who charge the same car nightly prefer it.
• Want a tidy look and long-term flexibility? → Untethered.
• Charge port awkward to reach? → Tethered with the right cable length, carefully positioned.
• Might change cars or want a neat wall? → Untethered.
• Public-facing or shared parking? → Untethered is common (users bring their own cable).

Practical considerations

• Cable length (tethered): think about which side your car’s charge port is on and where you park — a too-short tethered cable is a daily annoyance.
• Cable storage (untethered): you’ll keep the cable in the boot; fine for most, a faff for some.
• Both can be smart: the tethered/untethered choice is separate from smart features — get a smart charger either way (see our best EV chargers guide).
• Both are 7kW for most homes: this choice doesn’t affect charging speed — see 7kW vs 22kW.

Honest take

For a typical homeowner charging one car overnight on a driveway, tethered is the slightly more convenient everyday choice. If you value a clean look, future flexibility, or might change vehicles, untethered is the smarter long-term pick. There’s no wrong answer — it’s preference.
