New Spare charging cable 120-240 VAC compatable

I've been charging my 2020 Prius Prime at 240vac for a couple of years now using an adapter that's plugged into a dryer outlet. The factory 120vac charger/cable that came with the car (Toyota Part #G9060-47130) is plugged into the dryer's adapter and then cable from the charger is plugged into the Prius Prime. This adapter (EVDOUBLER) sells on eBay for $64.95 (8/5/24). Recently, I bought a new 2024 Prius Prime and it too, came with the same charger/cable (Toyota Part #G9060-47130) as my 2020 Prius Prime. The 2024 Prius Prime now charges at 240vac and takes approximately 1/2 the time that the 120vac charging would take. BTW, I was trained in electrical/electronic systems and feel that this is a very safe and inexpensive way to charge my Prius Primes.
