Choosing the Right EV Charger: Level 1 vs Level 2 Installation Explained

Author : daisy 0704 | Published On : 10 Jul 2026

You've got the electric vehicle. Now comes the decision that shapes your daily driving experience more than almost any other: how you'll charge it at home. Get it right and charging becomes something you never think about. Get it wrong and you'll spend evenings anxiously watching a slow-moving battery percentage. This guide breaks down the real differences between charging levels so you can approach EV charger installation knowing exactly what you need.

Level 1: the cable in the boot

Every EV ships with a Level 1 charging cable. It plugs into an ordinary 10-amp household power point — the same kind you'd use for a lamp — and trickles power into your battery. There's no special hardware to buy and, in theory, no installation required.

The catch is speed. Level 1 charging typically adds only around 10 to 15 kilometres of range per hour. Plug in overnight for ten hours and you might gain 100 to 150 kilometres. For someone with a short commute and a car that mostly sits at home, that can genuinely be enough.

But there are real limitations. Standard power points and household circuits aren't designed for the sustained, hours-long high draw of vehicle charging night after night. Relying on a general-purpose outlet long-term can stress old wiring. And if you ever have a big-driving day, Level 1 simply can't recover the range fast enough. It's a backup, not a foundation.

Level 2: the home charging standard

A Level 2 charger is a dedicated unit, hardwired to its own circuit at your switchboard. This is what most homeowners mean when they talk about installing a home charger. It charges several times faster than Level 1 — usually enough to fully replenish a typical EV battery overnight — and it's engineered specifically for the job, with proper safety devices and a dedicated circuit that isn't shared with anything else in the house.

The difference in day-to-day life is significant. With Level 2, you stop planning around charging. You plug in when you get home, and the car is ready by morning regardless of how far you drove. Because a Level 2 unit needs a dedicated circuit and correct protection, it must be installed by a licensed electrician. Professional EV charger installation from IllaVolt Electrical ensures the charger is properly matched to your switchboard and your home's capacity.

Which one is right for you?

Ask yourself a few honest questions. How far do you drive on a typical day? Do you have off-street parking near your switchboard? Do you have rooftop solar you'd like to charge from? Do you plan to keep the EV for years, or upgrade to a bigger-battery vehicle soon?

If you drive modest distances and rarely push your range, Level 1 might see you through in the short term. But for the overwhelming majority of owners — anyone with a normal commute, a family, or plans to keep their car — Level 2 is the sensible choice. The faster, safer, more convenient charging quickly justifies the one-off EV charger installation cost.

Smart features worth considering

Once you've decided on Level 2, you'll face one more choice: a basic charger or a smart one. Smart chargers connect to your home network and let you schedule charging for off-peak hours, monitor energy use, and in many cases prioritise charging from your solar panels. If you're on a time-of-use tariff or you have solar, a smart charger can cut your running costs meaningfully. For many Illawarra homeowners, that's an easy decision.

Don't forget the switchboard

Whichever charger you choose, the health of your switchboard matters. Older boards may not have space for a new dedicated circuit, or may be due for an upgrade to safely handle the extra load. A good electrician will assess this as part of your EV charger installation so there are no surprises. It's far better to sort this out at installation than to run into trouble later.

The takeaway

Level 1 is the free, slow starting point that comes in the box. Level 2 is the proper home charging solution that turns your EV into an effortless part of daily life. For nearly everyone, the answer is a professionally installed Level 2 charger — and the best first step is a chat with a licensed local electrician who can look at your home and recommend exactly the right setup.
