r-tec WCU-11 Portable

Overview

WCU-11 Portable is the portable version of the r-tec EV charging portfolio. In situations where fixed wallbox installation is not possible — long-trip accommodation, backup/guest use, hotel/restaurant visits, service vehicles, mobile teams — it offers a mobile charging solution that the user carries with them. The device has two ends: on one side a connected socket (Schuko home socket or CEE industrial socket), on the other a Type 2 EV connector. The intermediate device creates the smart control + safety layer.

Why portable charging?

Practical scenarios for EV owners:

• Accommodation — Charging overnight if a hotel/boutique guesthouse has a Schuko socket (3.7 kW × 8 hours = ~30 kWh gain).
• Guesting — Connecting to a Schuko when there is no fixed wallbox during a relative/friend visit.
• Business trip — 4-5 hour city visit for a meeting, hotel or workplace entrance.
• Backup — Plan B used when the fixed wallbox is broken or there is an electrical issue.
• Service vehicle + field team — Daily charging need of mobile technicians (in workplaces with CEE sockets).

WCU-22 Wallbox permanent infrastructure, WCU-11 mobile backup + flexibility. Together they provide a premium use experience.

Multiple socket input — smart detection

The distinguishing feature of WCU-11 is multiple input socket support. Typical adapter set:

Input type	Max. current	Max. power	Typical location
Schuko (standard home socket)	10 – 16 A	2.3 – 3.7 kW	Home, hotel, restaurant
CEE 16 A (blue industrial socket)	16 A	11 kW (3-phase)	Workshop, camp, workplace

The device smartly detects the connected socket type and adjusts the draw power according to the mains capacity — the user does not make manual adjustments. On Schuko, it automatically limits the current to 10 A to prevent plug burning.

Naming note — PC-11 vs WCU-11

Two names were used in the historical course of this model:

• PC-11 — Past label on the r-tec.com.tr marketing site.
• WCU-11 PORTABLE — r-technic technical portal and current product label.

In current and future marketing copy, WCU-11 Portable has been adopted as the standard name; provides parallel naming with WCU-22 Wallbox (both with WCU prefix). Old PC-11 references are equivalent to this model.

Standards and compliance

• IEC 62196-2 — Type 2 connector standard.
• IEC 61851-1 — Mode 3 AC charging communication protocol.
• EN 61851-22 — Mode 3 device safety.
• EN 60364-7-722 — EV charging electrical installation (also valid for portable).

Field discipline

• Socket type and cable length must not trigger heating at continuous full-load current. Long-term 16 A draw on an old Schuko socket can cause the wall socket to heat up; 10-13 A is set as a safe range.
• Schuko socket quality check — Standard home socket structure may be worn in 30+ year-old buildings. Continuous charging use may require socket replacement.
• Earthing test — Earthing must absolutely be active on the Schuko connection; the device gives an error if connected to an ungrounded socket.
• External residual-current protection mandatory — The device has no internal RCD; a 30 mA residual-current device (RCD) must be fitted in the supply panel.
• Location — Can be used outdoors in the rain (IP54) but the socket beds must be kept closed; in continuously rainy locations, WCU-22 fixed installation is preferred.
• Cables must not be excessively pinched — Cable bend radius must be a min. of 10 cm; sharp bending leads to conductor breakage.
• Storage after charging — The device should be put away in a cool + dry place; remaining for long periods in the vehicle in high temperatures wears the battery/electronic parts.

Target user profile

• Individual EV owner — Apartment dwellers who cannot install a fixed wallbox (shared garage limited).
• Hotel and boutique accommodation operator — Accommodation that meets guest EV needs but has not made a wallbox investment.
• Corporate vehicle fleet manager — Backup charging solution for company service vehicles.
• Field mobile team — Charging need on the road for service, sales, audit teams.

Model notes

Socket type and cable length must not trigger heating at continuous full-load current. Although the device is in IP54 class, WCU-22 Wallbox fixed installation is recommended for continuous rain and continuous outdoor use. WCU-11 is optimal for flexible + backup + mobile scenarios — not designed for long-term fixed use.
