Lexus RZ home charger: charge time and which amps it can use

Charge time by charger amps

A charger's amp rating sets its power on a 240 volt circuit; the car then takes the smaller of that and its own onboard limit. Each row is one standard charger rating.

Power is amps times 240 volts. Full-charge times divide the EPA wall energy for a full charge (68 to 81 kWh), which already includes charging losses, by the rate the car accepts. The comparison column reads the highest-rated trim. The last column counts chargers in this database rated at exactly that current that plug into this car directly.

How these Level 2 times compare with a standard 120 volt outlet, in hours to full and miles added overnight for every vehicle family, is in Level 1 vs Level 2 charging compared by vehicle.

Chargers that fit the Lexus RZ, by amps

Selection rule, in full: only chargers with a verified price appear; grouped by the charger's rated current; the 5 lowest verified prices in each group. Nothing here is an editorial pick.

Prices were verified at a named seller on October 5, 2026. Rate and full charge assume the 11 kW onboard charger; lower-rated trims cap lower, as the table above shows.

Charge rate depends on which Lexus RZ you have

This family does not charge at one speed. 2 different AC intake ratings ship across the 14 trims, and a charger cannot exceed the one in your car. Buying for the higher figure when you own the lower trim buys nothing.

Intake figures are manufacturer-published, not derived from EPA data. Source: 2026 LEXUS RZ ADDS MORE POWER AND PERFORMANCE.pdf (pressroom.lexus.com), checked July 23, 2026. Full-charge times assume 68 to 81 kWh drawn from the wall, which already includes charging losses.

What a full charge costs

Electricity is the whole running cost, and it is the number that varies most by where you live. A full 68 to 81 kWh at the Lexus RZ, priced three ways:

Rates are the EIA residential series, July 2026. Your own utility and any time-of-use plan decide the real figure.

The circuit this car needs

A home charger is a continuous load, so the National Electrical Code sizes both the breaker and the conductor at 125 percent of its draw. A charger matched to this car's 11 kW ceiling pulls 46 amps at 240 volts, which needs a 60 amp circuit rather than the 46 amp one the arithmetic alone suggests. That gap is where most installation quotes go wrong.

Of the 180 chargers that plug in directly here, 86 meet or beat the car's ceiling. Going above it changes nothing for this vehicle, though it leaves headroom for a future one that draws more.
