Three-Phase Portable Charging at Home: Choosing Between Workersbee Dura Charger and ePort C
Aug 20, 2025
Home charging should feel effortless. If your house or building has three-phase power, a portable Mode 2 charger can deliver wallbox-level speed without a permanent install. This guide explains when 11 kW vs 22 kW makes sense, how Mode 2 protection works, and how to choose between Workersbee’s Dura Charger and ePort C.
Why three-phase portable makes sense
Wallbox speed, zero install: Plug into a properly installed red CEE outlet and get 11 kW (3×16 A) or 22 kW (3×32 A).
Portable investment: Take it when you move house, change parking spots, or need charging at a secondary location.
Future-proofing: Even if today’s EV tops out at 11 kW AC, a 22 kW unit can serve the next vehicle or visitors.
11 kW or 22 kW — which is right for you
11 kW suits overnight top-ups, apartments with limited supply, and models whose onboard AC max is 11 kW.
22 kW is great for larger batteries, multi-car households sharing one outlet, or late returns that need a fast turnaround before morning.
Remember: your EV’s onboard charger sets the ceiling for AC charging speed.
How Mode 2 safety works (simple version)A Mode 2 charger embeds control and protection in the in-cable box. It checks the supply before charging, monitors temperature, and includes residual-current/leakage protection so the system shuts down safely if something looks wrong. Look for a robust enclosure (e.g., IP67) and clear status indicators.

Set-up basics for homeowners
Ask a licensed electrician to install the correct red CEE three-phase outlet: 16 A for 11 kW, 32 A for 22 kW.
Verify panel capacity and appropriate circuit protection.
Plan cable routing and a dry storage spot; add a hook or bracket near the outlet for daily convenience.
Everyday ways to use it
Driveway or carport: hang the control box, plug in when you park, coil loosely after use.
Assigned garage bay: dial down current if the building has limits.
Second home or workshop: take wallbox-level AC wherever there’s a compatible outlet.
Multi-car evenings: a 22 kW outlet lets you top up cars sequentially with shorter dwell times.
Care and cable managementKeep connectors capped, avoid tight coils while warm, rinse winter road grime off the cable, and store in a clean, dry bag. These small habits protect seals and extend service life.
Which one should you choosePick Dura Charger if you value adaptability across different locations and power supplies, or you expect to move the charger frequently.Pick ePort C if you mainly charge at one place with a three-phase outlet and want the simplest path to fast, reliable AC top-ups.
FAQ
Do I need a red CEE outlet? Which size?Yes. Use a three-phase red CEE installed by a licensed electrician: 16 A (up to 11 kW) or 32 A (up to 22 kW), matched with appropriate breakers and wiring.
Will a 22 kW charger speed up an EV limited to 11 kW AC?No. The EV’s onboard charger decides the AC rate. A 22 kW unit still helps with future vehicles or shared use.
Can ePort C run on single-phase?ePort C is purpose-built for three-phase. If you often switch between single- and three-phase locations, Dura Charger is the better fit.
Is outdoor charging safe in rain or snow?Both units feature rugged, sealed enclosures (IP67). Keep caps on when not in use and avoid submerging connectors in standing water.
Can I adjust charging current?Yes. Both products support current adjustment to match site limits or avoid nuisance trips.
What accessories are worth adding?A wall hook, connector caps, carry case, and a storage bag. If you need different plug types or cable lengths, contact Workersbee for OEM/ODM options.
How do I decide between 11 kW and 22 kW?Match to your EV’s AC limit and your site’s capacity. 11 kW covers most overnight needs; 22 kW shines for bigger batteries, shared outlets, or quick turnarounds.
