Your Complete Guide to Home EV Charging
With more EV models hitting the road every year, choosing the right home charger can feel overwhelming. This guide breaks down everything you need to know - from power levels to smart features - so you can make the right choice for your home and vehicle.
Step 1: Know Your Power Needs
Home EV chargers range from 3.5kW to 22kW. The right power level depends on three factors:
- Your vehicle's onboard charger - Most EVs can accept 7kW-11kW. Some newer models support 22kW with 3-phase power.
- Your home's electrical setup - 7kW works on a standard 32A circuit. 11kW+ requires 3-phase power.
- How fast you need to charge - Overnight charging (8 hours) works with 7kW for most EVs. Need faster? Go higher.
| Charger Power | Range Per Hour | Full Charge (60kWh battery) |
|---|---|---|
| 3.5kW | ~20 km/h | ~17 hours |
| 7kW | ~40 km/h | ~8.5 hours |
| 11kW | ~65 km/h | ~5.5 hours |
| 22kW | ~120 km/h | ~3 hours |
Step 2: Portable vs Wall-Mounted
Portable chargers (3.5kW-11kW) are compact, travel-friendly, and plug into standard outlets. Perfect for road trips or homes where you don't want permanent installation.
Wall-mounted chargers (7kW-22kW) are permanently installed for daily home charging. They offer faster speeds, smart features like WiFi and RFID, and a sleek permanent setup.
Step 3: Smart Features Worth Having
- WiFi + App Control - Schedule charging, monitor energy usage, get notifications
- RFID Access - Restrict usage to authorized users - great for shared driveways
- OCPP Support - Future-proof compatibility with charging management platforms
- Multiple Start Modes - Plug & Play, RFID card, or App control
Step 4: Check Compatibility
GIZNT chargers work with 99.9% of EVs on the road. All models feature Type 2 connectors (the European and international standard). Tesla vehicles may need an adapter in some markets.
Our Recommendation
For most homeowners, a 7kW or 11kW wall-mounted charger hits the sweet spot - fast overnight charging with smart features at an accessible price. Need portability? Check out our portable charger range.
