Smart charging cable plugged into an electric company car charging at home in Switzerland

A smart charging cable is a mobile EV charger that measures every charge and sends it to an app over Bluetooth, Wi-Fi or a mobile network. In Switzerland the most complete models cost about CHF 700.– to 1'500.– each, and on a T23 socket they charge at about 3 kW, like any good mobile charger. To reimburse home charging for a fleet, you do not need a smart cable at all.

This guide explains what a mobile charger is, how much power it really delivers on Swiss sockets (T13, T23, T25, CEE), compares the models you can buy in Switzerland and answers the question fleet managers ask most: do you need a certified meter to reimburse charging? A word of transparency: Voltaback sells no hardware. It is software that reimburses home charging at real cost, so we can tell you honestly when a smart cable is useful and when it is not.

Type 2 cable, mobile charger, smart cable: what is the difference?

Three products look alike but do different jobs.

A Type 2 cable (Mode 3) connects a wallbox or public charging station to the car. It has no control electronics: the station manages the charge. This is the cable you keep in the boot for public chargers.
A mobile charger (Mode 2) plugs into a household or industrial socket. Its built-in control box (in-cable control box, ICCB) talks to the car, sets the current and handles protection: fault-current detection, earth monitoring and sometimes a temperature sensor in the adapter.
A "smart" cable is a mobile charger with an energy meter and connectivity (Bluetooth, Wi-Fi, sometimes a SIM card). It logs each session: kWh, duration and time.

The Electrosuisse brochure on charging infrastructure (in German) describes these charging modes and notes that Type 2 has become the European standard for AC charging. To choose the right cable for your use, see our charging cable page.

How much power do you really get from a Swiss socket?

At home, a mobile charger never charges faster than the socket feeding it. Real power is the lowest of three limits: the socket, the mobile charger and the car's on-board charger.

Swiss socket	Current allowed by the mobile charger	Charging power
T13 (household)	8 A, single-phase	about 1.8 kW
T23 (16 A)	13 A, single-phase	about 3 kW
T25 (three-phase household)	3 × 13 A	about 8.9 kW
CEE16 red	3 × 16 A	11 kW
CEE32 red	3 × 32 A	22 kW, only with a 22 kW charger and a car that accepts 22 kW

Juice Booster Swiss adapter values according to the manufacturer: T13, T23, T25, CEE16.

Two Swiss specifics change the picture compared with guides written for other countries:

No single-phase 32 A charging. The grid operators' technical rules (Werkvorschriften) allow only three-phase connections above 3.7 kVA and forbid charging at 32 A on one or two phases. The "7.4 kW on a blue 32 A socket" often quoted abroad is not an option here.
The on-board charger is the limit. Most electric cars have an 11 kW on-board charger, so a 22 kW mobile charger is no faster than an 11 kW one, even on a CEE32.

Source for point 1: Electrosuisse, chapter on utilities.

The upshot: most employees charge in their own garage on a T23 or T13. The 11 or 22 kW printed on the box only matters on the road, on a building site or in a workshop with CEE sockets. To choose the socket itself, read our comparison T13, T23 or CEE: which socket to choose.

How we compared the chargers

We used the criteria that matter when you equip one driver or a whole fleet:

Swiss compatibility: T13, T23 and T25 adapters available and approved in Switzerland, with automatic adapter recognition.
Usable power on the driver's installation, not the device's maximum.
Meter: present or not, certified or not.
Connectivity: Bluetooth (data on the phone), Wi-Fi (depends on the home network) or SIM (data plan per device).
Robustness: IP rating, crush resistance, behaviour in the cold.
Price, multiplied by the number of vehicles, plus adapters.

The best mobile EV chargers available in Switzerland

1. Juice Booster 3 air: the Swiss benchmark

Best matched to Swiss sockets. A mobile charger with Swiss design and development, 1.4 to 11 kW, waterproof and dustproof to IP67, 700 g without cable, with an app, RFID cards and DC fault-current detection (6 mA DC). It recognises the adapter and sets the current automatically.

Manufacturer price: CHF 1'299.– (Basic Set), CHF 1'449.– (Traveler Set), CHF 79.– per extra Swiss adapter (Basic Set, Traveler Set). Swiss retailers are often cheaper.
Strength: T13 adapter with temperature sensor, plus T23 and T25 adapters built for Switzerland.
Limit: 11 kW maximum; no meter certification highlighted.
Best for: employees who charge on many different sockets, field technicians.

2. NRGkick: the most fleet-oriented

Austrian mobile charger up to 22 kW, with app, Wi-Fi and Bluetooth, plus SIM and GPS versions that send session data without relying on home Wi-Fi. The manufacturer offers dedicated fleet solutions (nrgkick.com).

Indicative Swiss price: about CHF 750.– to 1'500.– depending on version and adapter set.
Strength: independent data transmission, integration with fleet platforms.
Limit: price per vehicle, data plan for SIM versions, a device to manage at every joiner and leaver.
Best for: fleets that want hardware metering on cars charged in many places.

3. go-e Charger Gemini flex: best power for the price

A 22 kW mobile charger with Wi-Fi, RFID and the open OCPP protocol. One Swiss retailer listed the Gemini flex 2.0 22 kW at CHF 680.40 (Buchmann), with variable availability.

Strength: price, open software.
Limit: some adapter sets sold abroad are not approved for Switzerland; check the T23 or T25 adapter before buying.
Best for: tech-savvy drivers, small fleets that handle their own data.

4. The simple mobile charger with no connectivity

A T13 or T23 mobile charger with no meter or app, or a Juice Booster 2 (22 kW, no connectivity), does exactly the same electrical job. If you always charge in the same place, it is usually enough, as long as it is designed for Swiss sockets.

go-e Gemini flex 2.0	22 kW (about 3 kW, adapter-dependent)	to be checked	Wi-Fi, OCPP	about CHF 680.–	Tech-savvy users
Simple mobile charger	3 to 22 kW by model	by model	none	varies	Always charging in one place
Voltaback (software)	any existing installation	not needed	Software measurement, 1.22 % relative error	no hardware	Reimbursing a fleet's home charging

Prices checked in November 2026, excluding installation; they change often.

Our verdict by need

Commuter charging every night in the same place: a mobile charger matched to their T23 or CEE socket is enough; connectivity adds very little.
Travel and varied sockets (chalet in Verbier, family in Basel, hotels): Juice Booster 3 air with Swiss adapters.
Hardware metering without Wi-Fi: NRGkick, SIM version.
Best 22 kW budget option: go-e Gemini flex, after checking the adapters.
Company car whose charging is reimbursed: no smart cable. Software measures charging on the existing installation and applies the employee's own tariff.

Do you need a MID meter to reimburse home charging?

No. No Swiss tax rule requires a certified meter to reimburse electricity for a company car. The principle of the model expense regulations of the Swiss Tax Conference (SSK/CSI, in German) is reimbursement of actual expenses against proof: you document the kWh charged for the vehicle and the price the employee actually pays.

This is where smart cables fall short. Their built-in meter is usually not certified, and it only measures the energy flowing through it, without knowing the home's tariff. Voltaback relies on the home's MID-certified meter, not on a standalone cable meter. Each session is linked to the right vehicle and valued at the employee's contract price, and the measurement was audited by an independent third party with a relative error of 1.22 %.

Price matters as much as measurement. According to ElCom, the 2026 median household tariff (H4 profile) ranges from 21.9 Rp./kWh in Zug to 33.2 Rp./kWh in Basel-Stadt, excluding VAT, with Geneva at 24.9 and Vaud at 30.4 (ElCom). A single flat amount cannot be fair to an employee in Zug and another in Lausanne.

The limits of smart cables for a fleet

For a private driver, a smart cable is a convenience. For a fleet, it becomes an inventory to manage.

Multiplied cost: 40 vehicles with a CHF 1'300.– charger each add up to CHF 52'000.– of hardware, before adapters and replacements.
Loss and theft: a mobile charger lives in the boot or in the parking space; if it disappears, you buy another one.
Data gaps: no Wi-Fi in the underground car park, an app that has not synced, a charge done with another cable. Every gap is a charge without proof.
Joiners and leavers: each staff change means recovering, resetting and reassigning the device.
No link to the tariff: the cable measures kWh, not francs. You still have to collect every employee's electricity bill.

A smart wallbox has similar limits, plus an installation at every home: see our article on connected charging stations for fleets.

Reimbursing without a smart cable: software measurement

The simplest route for a fleet is to add nothing at all at the employee's home. Voltaback is 100 % software: it connects to more than 48 car brands, records each charging session (date, duration, kWh), applies the real price of the employee's electricity contract and produces a monthly statement for payroll.

Any installation: T13, T23, CEE or wallbox, house or condominium, with or without a smart meter. See our article on charging without a smart meter.
Compliance: documented actual expenses, neither salary nor subject to AHV/AVS contributions; ISO 27001 certified; the company never receives drivers' location data, in line with the Swiss Data Protection Act (nDSG / nLPD).
Nothing to manage: nothing to buy, lose or recover.

Frequently asked questions about smart charging cables and mobile EV chargers

No, a smart cable does not charge faster than a standard mobile charger on the same socket. On a T23 both reach about 3 kW; speed depends on the socket and the car's on-board charger, not on the app.

A Type 2 cable connects a charging station to the car and contains no control electronics, whereas a mobile charger plugs into a household or CEE socket and has the control and protection box built in. Without a wallbox at home, you need a mobile charger.

Yes, the Juice Booster 3 air has Swiss T13, T23 and T25 adapters at CHF 79.– each from the manufacturer. The device recognises the adapter and limits the current automatically: about 1.8 kW on T13 and 3 kW on T23.

Rarely: you need a red three-phase CEE32 socket and a car that accepts 22 kW AC, which most models do not. For almost every driver, an 11 kW charger covers all uses.

No, no Swiss rule requires a MID-certified meter for this reimbursement. The employer must be able to document the kWh charged and the price paid by the employee, which audited software measurement provides without hardware.

Yes, software such as Voltaback tracks every home charge without a smart cable or wallbox, on the employee's existing installation. It applies the tariff of their electricity contract and produces a monthly statement.

Equip your drivers with the right tool, not necessarily a cable

A good mobile charger built for Swiss sockets is still useful for charging. But to reimburse a fleet's home charging, software measurement saves you buying, tracking and replacing one device per vehicle.
