A mobile connector is a portable charging cable — a type of EVSE — that plugs an electric car into an ordinary power outlet. It has a wall plug on one end, a small control box in the middle, and a vehicle connector on the other end. Some car makers use “mobile connector” as the product name for the portable cable they sell, but the term describes this generic device, not one brand.
Key Takeaways
- A mobile connector is a portable EVSE cable: wall plug, control box, vehicle connector.
- The control box checks the connection and sets the current — it is not a plain cable.
- Speed is set by the outlet: about 1 kW on a household socket, up to its rating on 240V.
- A wallbox suits daily charging; a mobile connector is the travel and backup option.
The Three Parts of a Mobile Connector
| Part | What it does |
|---|---|
| Wall plug | Connects to the outlet — a household plug for Level 1, or a 240V plug such as NEMA 14-50 on many Level 2-capable units |
| Control box (in-cable EVSE) | Checks the connection, talks to the car, sets the maximum current, and stops the flow if it detects a fault |
| Vehicle connector | Locks into the car’s charge port — J1772, NACS or Type 2 depending on the car and region |
The box is the point. A plain cable could carry power, but EVs charge for hours at high current, so the control box confirms the car is connected properly before any current flows, and the car’s onboard charger then converts AC to DC for the battery. Our explainer on what an EV mobile charger is covers roadside and service uses of the wider “mobile charging” term, and the portable EV charger buying guide compares cable types in detail.
Mobile Connector vs Wallbox
Both do the same job — controlled AC charging — with different trade-offs. A mobile connector needs no installation, travels in the boot, and is limited by the outlet it plugs into: about 1 kW from a standard US household outlet (Level 1), which the U.S. DOT equates to roughly 2–5 miles of range per hour, or up to its rated power on a 240V outlet. A wallbox is fixed, runs on its own circuit, and is the better fit for daily charging at 7 kW and above. Many drivers own both: the wallbox at home, the mobile connector for travel and as a backup. Our guide to whether portable EV chargers are worth it works through who needs which.
Using a Mobile Connector Well
- Plug it directly into the outlet — no extension cords, which overheat under hours of continuous load.
- Uncoil the cable fully so heat can escape.
- Match the current setting to the outlet and breaker; a 240V outlet does not make every setting safe.
- Keep the control box off the ground in wet weather where you can, and check its IP rating.
- Store it dry in the car; it is your backup when a destination has an outlet but no charger.
The safety habits matter more than the brand on the box. The U.S. DOE’s home charging guidance treats portable equipment as a normal part of home charging when it is used on a sound outlet and circuit.
Mobile Connectors From EVDANCE
EVDANCE portable chargers follow the same pattern: the EV-ACS3210T 32A NACS portable charger gives about 7.7 kW on a NEMA 14-50 outlet with six current steps from 10 to 32 A, and the EV-ACS3210E 32A Type 2 portable charger covers single-phase Type 2 cars at about 7 kW; both are IP66. Choose by your car’s connector and the outlets you actually have.
Frequently Asked Questions
Is a mobile connector the same as a granny charger?
Roughly, yes. “Granny charger” is the UK nickname for the same portable cable used on a household socket. “Mobile connector” is the more formal product term, and it also covers 240V-capable units, not just slow socket charging.
Can a mobile connector charge as fast as a wallbox?
Only if the outlet can feed it. On a household outlet it is limited to Level 1 speeds; on a correctly installed 240V outlet, a 32 A unit reaches about 7.7 kW — wallbox territory — but it still depends on a receptacle rather than its own hardwired circuit.
Does every EV come with a mobile connector?
No. Inclusion varies by maker, model and market, and some makers have unbundled the cable or made it a paid option. Check what is in the boot before you rely on one, and see our guide to buying a portable EV charger if you need to add one.
