Level 1 vs Level 2 EV charger: which do you need at home?

Level 2 fills your car overnight; Level 1 often can't keep up

The real difference is whether your car is full by morning. A Level 2 wall charger delivers a full recharge overnight.1electricvehiclecouncil.com.auView source You plug in after work and it's done. A Level 1 charger uses a normal power point and the cable that came with the car. It adds only about 10 to 20 km of range an hour, so a full top-up on a big battery can take many hours, often more than one night.2transport.nsw.gov.auView source

That's why Level 2 is the common pick: it's much faster and keeps up with everyday driving. For most homeowners, that overnight refill is the whole reason to buy it.3racv.com.auView source Speed for its own sake isn't the point. Being full each morning is.

Level 1 vs Level 2, side by side

Put the two next to each other and the gap is clear. The numbers below are range added per hour: how far you can drive on one hour of charging.

The real gap is range per hour, not just fast or slow

Think in kilometres, not labels. A Level 1 charger adds about 10 to 20 km of range for every hour it's plugged in.2transport.nsw.gov.auView source A Level 2 charger adds about 30 to 130 km an hour, depending on the unit and your car. Most homes land near the low end of that Level 2 range, because most Australian homes have single-phase power.3racv.com.auView source

On single-phase power, a common 7kW Level 2 charger adds around 35 to 40 km of range an hour.3racv.com.auView source Charge for two hours and you've replaced a normal day's driving. The same drive on Level 1 might need most of the night. So the gap that matters is simple: whether one night of charging keeps up with one day of driving. That gap also decides how the unit gets installed.

Level 2 is not a DIY job - have a licensed electrician fit it

A Level 1 charger needs no install. You plug the supplied cable into a power point you already have. A Level 2 charger is different. It runs on its own dedicated circuit, so fitting it is real electrical work. Have a licensed electrician check your home's wiring and circuitry first, then fit the charger and sign off the job.

This is the part to get right before you buy. A licensed electrician checks your switchboard and supply, fits the charger, and signs off the work. If you want to compare your supply options first, see our guides to 7kW vs 22kW chargers and single-phase vs three-phase power. What your home can take is a question for the electrician, not a guess from a product page.

What each costs - and where the money goes

Because Level 2 needs that electrician, the cost split is simple. Level 1 has no install cost: you use the cable that came with the car and a power point you already have. Level 2 is a proper install job, so most of its cost is the electrician's work, not the unit itself.

What that install costs depends on your switchboard, the cable run, and whether your supply needs any work. So the fair-price number is best checked for your own home. See what a Level 2 install costs in your suburb for a current estimate, then get quotes from a licensed electrician for your exact job. But that install cost is exactly why some drivers skip it.

When Level 1 is the smarter buy

Level 1 isn't a mistake. For some drivers it's the right call. It suits low-km drivers, plug-in hybrids, and people who only need an occasional top-up.3racv.com.auView source At about 10 to 20 km of range an hour, a Level 1 charger left on overnight can still replace a light daily drive.2transport.nsw.gov.auView source If you drive well under what that slow trickle replaces, the cheaper option does the job.

Plenty of Australian owners run this way on purpose. On EV forums, a common note from owners is that a basic trickle charger covers their daily driving, especially when they soak up spare rooftop solar during the day. One owner driving about 1,200 km a month said a cheap portable charger had been enough all year. So if your driving is light and you can charge slowly over many hours, Level 1 can save you the install.

How to decide: match the charger to your daily drive

Start with one number: how far you drive on a normal day. Then check whether a night of charging replaces it. A Level 1 charger adds about 10 to 20 km an hour, so over a long night it might replace 100 to 200 km (fine for a light driver, tight for a heavy one).2transport.nsw.gov.auView source A Level 2 charger adds about 30 to 130 km an hour, so a couple of hours covers most daily driving.

If your night of Level 1 charging keeps up with your day of driving, you can save the install. If it doesn't (or you'd rather not think about it), Level 2 is the safe buy. Most homes land on Level 2 for exactly that reason: it delivers a full recharge overnight and you stop watching the charge level.3racv.com.auView source

The bottom line

If you drive a normal day, buy a Level 2 charger. It delivers a full recharge overnight and keeps up without you thinking about it.1electricvehiclecouncil.com.auView source The reason it's the right buy for most homes is that overnight refill, not raw speed.3racv.com.auView source Keep Level 1 only if you drive low kilometres and a slow trickle over a long night is genuinely enough.2transport.nsw.gov.auView source

Either way, check your daily drive against one night of charging, and have a licensed electrician confirm what your home can take before you buy a Level 2 unit.3racv.com.auView source For the wider picture, see our full guide to home EV charging in Australia.
