If you drive < 100km a day, 2kW charging is more than enough.

10 hours when you sleep gives you 20kW which covers at least 100km for almost all EVs.

No extension. Make sure it is plugged in fully making full contact. Use approved chargers, can get the ones from PHEV or other EV brands. Fully uncoil the leads don’t coil it up (Google yourself why). Those China lazada ones… I won’t trust them cause it is a very big constant load.

The only challenge is where you need to do outstation trips then just plan your journey to hit DC chargers <20% SOC to juice up.

Not just turned on. In constant use, max heat for 10 hours. Even normal use of water heater we don't turn on max heat usually.

But yeah if you don't go more than 100km daily, no need for a dedicated wall box lah. if you have 2 EVs then you will need.

CEE socket wiring cheaper than installing a wallbox? Same wires kan for 1 phase. Then just get a wallbox installed.
Not like CEE sockets available all over, you got the portable charger also can't use everywhere.

With normal 3 pin charger, can use anywhere just lower the draw down to 7A to be safe.

Since you use less than 100km per week

Just limit charging draw to 7A & you’ll be fine lah, and charge everyday.

Basically the socket must not be looped, must be installed properly, and uses properly sized SIRIM cables. Your house developer is proper one and everything ikut spec it is fine to just plug and play. Problem only arises if corners were cut.

I did the same to a 1980s house, just plug in existing socket and draw 10A overnight no issues. Did it for 2 years. Of course back then no such bullshit as copper clad aluminum cables or shit China quality sockets.

Likewise I did to a 8 year old house developed by a top public listed developer, no issues with the original socket and 10A draw.

You sure it is not copper clad aluminum cables? Cause China factories love to pull that kinda wool. I ain't risking burning my house down.
