Lexus RZ Charging Cable

Quick recommendation

The Lexus RZ is the rare car where the expensive cable is genuinely the right one. Every 2026 Lexus RZ 350e, 500e and 550e has a 22 kW onboard charger as standard, replacing the 11 kW unit fitted to the earlier RZ 450e and RZ 300e. Lexus spells out what that needs in its own footnote: an AC charger with a three phase supply of 32 amps or greater. Almost nothing else we sell for can use a 32A three phase cable to its full capacity. This one can.

Every RZ charges through a Type 2 to Type 2 Charging Cable, which Lexus names directly in its own specification as a Type 2 Mennekes inlet. The charging flap sits on the nearside front wing, so the lead comes in at the kerb-side front corner.

At home, the 32A single phase cable is still the right buy, because one phase is all a domestic supply carries and 7.4 kW is where that stops, regardless of what the car could accept. The 22 kW headline only means anything where three real phases arrive. If you charge at a workplace or use 22 kW public AC posts, the 32A three phase cable takes a 2026 RZ from 11 hours 45 minutes to 4 hours. A 16 amp three phase lead would leave half that capability unused, which is the one place on this site where the heavier cable is not an upsell but a requirement.

The 16A single phase cable undoes the whole point of a 22 kW car, stretching a full charge to 23 hours 30 minutes and halving the miles put back each hour.

There is still a case for the domestic socket lead. Our Type 2 to 3-Pin Charging Cable carries 2.3 kW from a normal household outlet, roughly 11 miles an hour, which is a slow way to fill 77 kWh but a fast way to rescue an unplanned overnight stop. Our guide sets out what a house socket returns.

Lexus plug-in hybrids charge far more slowly and are covered on the Lexus NX 450h+ charging cable page, while the older electric hatchback is at Lexus UX 300e charging cable. The full set appears under Lexus EV charging cables. If you want to know what the IP figures below are actually protecting against, our IP ratings guide covers it.

CE certification against IEC 62196 Type 2 applies to every lead here, with an operating range of -30C to +50C, or +60C for the 3-pin. The Type 2 to Type 2 cables are rated IP55, the Type 2 to 3-Pin is IP67, all of it carries a 2 year manufacturer's warranty, and UK orders qualify for same-day dispatch on working-day orders placed before 2pm.

Lexus RZ Charging Times by Generation

RZ 350e, 2026 on, 77 kWh, up to 353 miles WLTP

Maximum onboard AC charging speed: 22 kW, three phase

Lexus quotes 3 hours 30 minutes for a 10 to 100 percent charge at 22 kW. The 4 hour figure above is empty to full with charging losses included.

RZ 500e and RZ 550e, 2026 on, 77 kWh, up to 311 and 280 miles WLTP

Maximum onboard AC charging speed: 22 kW, three phase

The recovery figures above are for the 500e. The 550e covers 280 miles, giving about 27 miles an hour on a 32A single phase cable and 80 on three phase.

RZ 450e and RZ 300e, 2023 to 2025, 71.4 kWh, up to 272 and 295 miles WLTP

Maximum onboard AC charging speed: 11 kW, three phase

Lexus publishes these capacities without saying whether they are gross or usable, so the times are close rather than exact. Cold air and high speeds will both trim the miles per hour shown here.

Lexus RZ Charging Cable FAQs

Which charging cable does a Lexus RZ need?

That depends on the year. A 2026 Lexus RZ 350e, 500e or 550e has a 22 kW charger and needs a 32A three phase cable to use all of it. An RZ 450e or RZ 300e from 2023 to 2025 has an 11 kW charger. Both take the same 32A single phase cable at home, where the supply rather than the car sets the limit.

Is the 22kW cable worth buying for a Lexus RZ?

On a 2026 RZ, yes, if you have three phase access. It is the only car we sell for where a 32A three phase cable is the difference between using the onboard charger fully and using half of it, taking a full charge from 11 hours 45 minutes to 4 hours. Lexus itself specifies a 32 amp three phase supply for the 22 kW figure.

Does the 22kW charger help at home?

No. Domestic supplies in Britain carry one phase and stop at 7.4 kW, so a 2026 Lexus RZ charges at exactly the same speed on a home wallbox as the older 11 kW cars did. The 22 kW capability only appears at a workplace or a 22 kW public AC post.

Is the Lexus RZ really only 6.6kW on AC?

No, and that figure should be ignored on a UK car. Some databases publish 6.6 kW single phase for the RZ 450e, which is the North American specification. Lexus UK's own technical documents state 11 kW three phase for the RZ 450e and RZ 300e, and 22 kW for the 2026 range.

What length of cable does a Lexus RZ need?

The charging flap is on the nearside front wing of a 4.805 metre car, so 5m works when you park nose in with the wallbox on the passenger side. Anything else on a car this long, and the lead has to run around the nose or down the far flank, which is where 10m is the safer order.

Does a Lexus RZ come with a charging cable?

Lexus lists a Type 2 Mode 3 32 amp cable and a 3-pin 10 amp cable as standard equipment on the RZ. Owners still buy a second lead for length, for a spare to leave at work, or because the supplied cable is single phase rated and cannot deliver the 22 kW the 2026 car is capable of.
