EV Home Prep Kit: What to Learn Before Installing Charging Gear
The first EV charging decision most households get wrong is the charger type. Most EVs work fine from a standard 10A wall socket overnight for typical daily driving. Spending $1,500–$3,000 on a fixed wall charger makes sense for higher-mileage drivers — but not for everyone. The prep work is figuring out which applies to your household before committing to either path.
- Standard 10A socket (Level 1): adds roughly 8–12km of range per hour. Enough for most drivers doing under 60km/day. No installation required.
- Portable EVSE ($150–$400): plugs into a standard socket but may offer a 15A or Type 2 connector option for faster charging. No fixed installation, moves with the car.
- Fixed wall charger (Level 2): 7–22kW, adds 40–130km per hour. Requires a licensed electrician for installation. Worthwhile for high-mileage drivers or households with rooftop solar.
- Fixed EV charger installation is electrical work. It requires a licensed electrician, potentially a switchboard upgrade, and council or DNO notification depending on the charger type and state.
What a portable EVSE actually gives you
A portable EVSE (Electric Vehicle Supply Equipment) is not the same as a fixed wall charger. It is a safety-enhanced cable that plugs into a standard wall socket and delivers controlled power to the car.
Why it matters before installing a fixed charger:
- You can start charging immediately without any installation
- It reveals your actual daily charging needs before you commit to a fixed charger size
- It travels with the car — useful at holiday homes, friends' properties or anywhere with a compatible socket
- It is a valid long-term solution for low to moderate daily driving
Where it falls short:
- Slower than a fixed Level 2 charger for high-mileage drivers
- Draws from a standard circuit — confirm the circuit is not shared with other high-draw appliances
- A 10A socket on a long cable in a garage or driveway is not an ideal permanent setup
The four questions that decide which charger type fits
1. How many kilometres do you drive per day on average?
This is the only number that matters for deciding between a standard socket and a fixed charger.
| Daily distance | Level 1 (10A standard socket) | Portable EVSE | Fixed Level 2 wall charger |
|---|---|---|---|
| Under 40km | Usually fine overnight | Option if slower | Not necessary for most |
| 40–80km | Borderline — depends on parking time | Good option | Worth considering |
| 80km+ | Insufficient — car won't fully charge overnight | May not keep up | Recommended |
2. Is the car parked at home during off-peak hours?
If you are on a time-of-use tariff with overnight off-peak rates, charging between 10pm and 6am costs significantly less per kilometre than peak-hour charging. A cheap overnight rate only helps if the car is actually home during that window. Commuters who return home by 7pm and park overnight are well-positioned for this.
3. Is there rooftop solar?
A household with rooftop solar and a car that is home during the day can configure a portable EVSE or a smart wall charger to prioritise charging from solar export. This shifts EV charging cost to near-zero. The car must be home and plugged in during solar generation hours — typically 9am to 3pm.
4. What is the switchboard situation?
A fixed Level 2 wall charger draws 7–22kW — often requiring a dedicated circuit and potentially a switchboard upgrade. Older switchboards with limited spare capacity may need an electrician's assessment before any fixed installation proceeds. A portable EVSE avoids this entirely, though it should still be on a circuit that can handle continuous high-draw use.
What you can buy without installation
Portable EVSE cables compatible with Australian Type 2 sockets are available on Amazon AU and represent the first practical step for any new EV owner. Look for:
- SAA/RCM certification — essential for Australian electrical safety compliance
- 10A and 15A socket compatibility — 15A sockets deliver faster charging where available
- Type 2 connector — compatible with most EVs sold in Australia

What requires a licensed electrician
- Installing a fixed wall charger (any brand, any output level)
- Running a dedicated circuit for EV charging
- Upgrading a switchboard to accommodate additional load
- Installing a 15A or 32A socket in a garage specifically for EV use
These are not DIY tasks. In most Australian states, electrical work beyond changing a light globe requires a licensed electrician. Fixed EV charger installation also typically requires the installer to notify the local DNSP (Distribution Network Service Provider).
- New EV owners figuring out whether a fixed charger is worth it
- Households with solar who want to align charging with solar generation hours
- Anyone on a time-of-use tariff exploring whether off-peak charging changes their cost per kilometre
- Anyone ready to install a fixed charger today — that conversation is with a licensed electrician, not a product guide
- Apartment residents without dedicated parking or a dedicated circuit available
Start with a portable EVSE and charge from a standard socket. Three months of daily charging data tells you whether you're running out of charge before morning — and whether a fixed charger is genuinely necessary or just nice to have.
