Lexus UX300e Charging Cable
Quick recommendation
The Lexus UX 300e takes a Type 2 to Type 2 cable, and the 32A version is the one to order. Both UK batteries share the same onboard charger, rated at 6.6 kW, and that is the number that decides everything on this page. A 32A cable is rated to carry 7.4 kW, comfortably above what the car will ask for, which is exactly what you want.
Before you order, make sure you have the right Lexus. The UX 300e is the full electric model. The UX 250h and UX 300h sit beside it in showrooms with almost the same badge, but they are self-charging hybrids with no socket anywhere on the body, so no cable on this page will do anything for them. If your car has never been plugged in, it is one of those.
Two batteries have been sold here. Cars from 2021 to 2022 carry 45 kWh usable from a 54.35 kWh pack. From 2023 Lexus fitted a much larger 72.82 kWh pack with 64 kWh usable, but left the onboard charger alone at 6.6 kW. The result is that the newer car has considerably more range and takes considerably longer to fill: roughly 7 hours 45 minutes on a 32A cable for the early car against about 11 hours for the later one. Both are still comfortably inside an overnight window on an off peak tariff.
There is no point paying for the three phase cable here. The 6.6 kW ceiling is single phase and lives in the car, so a three phase post cannot feed it any faster. The 16A cable holds the car back to 3.7 kW and turns the big battery into a job of nearly twenty hours, so it only makes sense if your supply genuinely cannot offer more. The Type 2 to 3 Pin cable runs at 2.3 kW and is for emergencies and overnight stays away, not for filling 64 kWh from flat.
One point worth knowing: the UX 300e uses a CHAdeMO port for DC rapid charging rather than the CCS fitted to most newer cars. That has no bearing on which cable you buy, since your cable is only ever used for AC charging.
Our Type 2 to Type 2 cables are IP55 rated, our Type 2 to 3 Pin cables are IP67, and both come with a 2 year manufacturer's warranty and same-day dispatch on working-day orders placed before 2pm.

Lexus UX 300e Charging Cable FAQs
Which cable does the Lexus UX 300e need?
A Type 2 to Type 2 cable, and we would order the 32A. Every UK UX 300e has a 6.6 kW onboard charger, and the 32A cable is rated to 7.4 kW, so it never becomes the restriction. The 16A alternative would cap the car at 3.7 kW and add hours to every charge for no real saving.
How long does a UX 300e take to charge at home?
On a 32A cable, about 7 hours 45 minutes for the 2021 to 2022 car with 45 kWh usable, and about 11 hours for the 2023 car with 64 kWh usable. Both figures assume starting from empty, which is rare in practice, so a typical top up overnight will be a good deal shorter.
Does the Lexus UX 250h need a charging cable?
No. The UX 250h and the newer UX 300h are self-charging hybrids with no charging port fitted, so there is nothing to connect a cable to. Only the UX 300e, which is Lexus's full electric version of the same car, has a Type 2 socket and needs one of the cables listed here.
Is a three phase cable worth it on a UX 300e?
No, and this is one case where we would steer you away from it. The 6.6 kW limit is built into the car's single phase onboard charger, so plugging into a three phase post changes nothing. You would pay more for a heavier cable and see exactly the same 7 hours 45 minutes or 11 hours.
Does the 72.8 kWh UX 300e charge any faster?
Not on AC. Lexus enlarged the battery for 2023 from 54.35 kWh to 72.82 kWh gross but kept the same 6.6 kW onboard charger, so the bigger pack simply takes longer to fill: about 11 hours rather than 7 hours 45 minutes. The cable you need is identical for both cars.
Should I choose the 5m or 10m UX 300e cable?
Five metres works when your charge point is within a couple of paces of the car's socket and you always park the same way round. Ten metres is worth having if the unit is on the far side of a shared drive or a garage wall, or if you regularly use car park bays. Charging speed is unaffected.
