At a public site, the question is who owns the cable. Tethered, the site owns it: the cable lives on the post and is the operator’s to protect and replace. Socketed, drivers carry their own leads and the post stands bare between sessions. Neither wins in general — the driver population and the site’s exposure decide it.
Key Takeaways
- Tethered: the operator owns the cable — universal readiness, plus its wear, exposure and replacement.
- Socketed: drivers carry the lead — nothing to damage at the post, no service for a driver without one.
- Decide from site evidence — users, exposure, repair route — not general preference.
- Specify cable lengths only where the listing states them; an unstated length is a written confirmation, never an assumption.
The Two Forms, Precisely
A tethered charger carries a fixed cable; a socketed charger offers an outlet only, and the lead belongs to the driver. The distinction is on the car side only — how the unit connects to the building supply is a separate decision, covered in our guide to hardwired vs plug-in chargers. For home and workplace posts the trade-offs are weighed in our comparison of tethered vs socketed wallbox chargers; this article stays on unsupervised public sites.
The Public-Site Comparison
| Dimension | Tethered at a public site | Socketed at a public site | The site evidence that decides |
|---|---|---|---|
| Driver readiness | Works for every arrival, cable or not | A driver without a lead cannot charge at all | Who uses the site — registered regulars, or passing visitors who may carry nothing |
| Cable wear | One cable takes every session’s wear; replacement is the operator’s service line | Wear sits on drivers’ own leads; the post has no cable to wear out | Whether the operator can service a cable quickly when it wears |
| Exposure between sessions | A cable hangs at the post day and night; damage and theft are the operator’s risk | Nothing hangs at the post; the socket is the only interface left exposed | The site’s security, lighting and incident history |
| Connector fit | The fixed connector must suit the cars that come — one connector per post | Drivers carry the lead their car needs, so connector variety moves to the lead | The connector mix of the vehicles the site genuinely serves |
| Failure shape | A damaged cable takes the whole post out of service until repaired | A driver’s faulty lead ends that session; the post serves the next car | The uptime duty the operator carries, and the repair route behind it |
No row declares a winner: the weights come from the site. A staffed, registered-user site carries a socket’s demands easily; an open visitor site with no fast repair route asks a tethered cable to survive unattended — a different bet.
Cable Facts When You Specify Tethered
Where tethered wins, specify from stated figures only: the EV-ACT5006T states a 25 ft cable; the EV-ACS3210E portable 7.5 m; the ACS1605PE 7.6 m. Other listings state none: the EV-AC03201T‘s connectors are tethered with no stated connector cable length; the EV-ACS3210T states none either. An unstated length is a written confirmation to obtain before bays are measured against it — never an assumed figure. Our cable length guide covers choosing a length.
Adapters at Public Sites
Adapter discipline is unchanged by the form choice. The JT02 is a NACS-to-J1772 adapter for AC charging only — up to 80 A — and never for DC fast charging or Superchargers. At a public site it is the driver’s own accessory, carried with their lead, not equipment left at a post.
The EVDANCE Model That Offers Both
The EV-ACT3204PE is listed as a 22 kW three-phase wallbox with a tethered Type 2 cable — chosen at order time, with RFID and app access and an IP66 enclosure either way. The public-site decision above is therefore a line in this model’s order, not a change of charger. Operators can raise a specific site via our commercial EV charging page or contact us.
Frequently Asked Questions
Which form do public sites choose more often?
There is no sourced figure, and none is invented here. The defensible answer is the decision itself: tethered where arrivals may carry no cable and the operator can protect and service one; socketed where users are known regulars and an unattended cable is a liability.
Does the socketed version charge more slowly?
No. On a model offered both ways the output is identical; the car’s acceptance sets the rate. The choice is about the cable — who owns it, wears it out and replaces it.
Can a tethered cable be replaced when it wears out?
A service question for the exact model’s supplier, to close in writing before the site depends on it: who supplies the replacement, and is the post out of service meanwhile? No replacement steps are given here: it is a manufacturer’s service job, not a site task.
