7kW vs 22kW – EV Charger Speed Compare Dubai
Compare 7kW single-phase and 22kW three-phase EV chargers. Which is best for your home charging speed and property power limits?
Quick answer: The main difference between a 7kW and 22kW EV charger is charging speed and power requirement. A 7kW charger operates on single-phase power, charging a standard vehicle in seven to ten hours, whereas a 22kW charger requires three-phase power and cuts charging time to three to five hours. Dispatched from Al Quoz, Fixer Guy provides professional installations for both types. Standard 7kW setups cost AED 1,500 - 6,500, and 22kW setups cost AED 2,500 - 9,500, subject to site survey. Message us on WhatsApp to inspect your main board phase capacity.
Comparing Charging Speeds and Currents
Both chargers deliver alternating current (AC) power to your car, but they draw power differently. A 7kW charger runs on single-phase power (230V, 32A), delivering roughly 40km of range per hour. A 22kW charger runs on three-phase power (400V, 32A across 3 lines), delivering up to 120km of range per hour.
Phase Power Availability
Your choice is limited by your property's electrical connection:
- Villas: Standard modern villas are connected to three-phase power, enabling fast 22kW charging.
- Apartments: Capped at single-phase power per meter block, meaning 7kW is the maximum possible speed.
Comparison Table: 7kW vs. 22kW
| Specification | 7kW Wallbox | 22kW Wallbox |
|---|---|---|
| Phase Requirement | Single-Phase (1P + N) | Three-Phase (3P + N) |
| Voltage & Current | 230V @ 32A | 400V @ 32A (across 3 lines) |
| Range Added / Hour | ~35 - 45 km | ~110 - 130 km |
DEWA Safety Regulations and Electrical Compliance
Any electrical installation drawing from Dubai's main power grid must comply with the Dubai Electricity and Water Authority (DEWA) regulations and the BS 7671 wiring standards. High-power appliances like electric vehicle chargers draw continuous current for hours, which can cause significant thermal stress on terminal blocks, main breakers, and power cables. If wired incorrectly, it can lead to insulation degradation, short circuits, or grid phase imbalances.
At Fixer Guy, we ensure compliance by installing dedicated Type A or Type B Residual Current Devices (RCDs) and miniature circuit breakers (MCBs) directly on your main distribution board. A Type B RCD is required for three-phase chargers because standard household breakers cannot detect DC leakage currents, which can disable your RCD protection. We also install dedicated copper earthing rods to verify ground fault pathways, ensuring that any short circuit is immediately diverted to the ground.
Factual Speed Comparison Reviews
"We had both a 7kW and a 22kW wallbox installed by Fixer Guy. Their comparison guide helped us choose a 22kW three-phase setup for our main villa and a 7kW single-phase setup for our garden house. Both charge perfectly!"

Safety Compliance & DEWA Regulations
As a professional electrical services provider based in Al Quoz, Fixer Guy strictly adheres to the Dubai Electricity and Water Authority (DEWA) regulations, BS 7671 wiring standards, and local municipality codes. Installing an electric vehicle charging station requires advanced load assessments to prevent main breaker trips, proper grounding/earthing systems, and matching RCD protection breakers (Type A or B depending on charger leakage). Our certified electricians wear appropriate personal protective equipment (PPE) and use calibrated testers to verify loop impedance, insulation integrity, and safety shut-off mechanisms. We only source charging equipment that matches local UAE standards (including Type 2 IEC sockets) and coordinate NOC approvals with developers (such as Emaar, Nakheel, and Dubai Properties) and building managements for hassle-free deployments.
