Using the Primes 120v Charger at 240 Volts, Cost $20 !!!

Since Rob43 isn't around anymore with his connectors, I found this on Amazon that has great reviews fyi:

 

Yes it looks neet, BUT I stongly suggest you to have a high quality 240V receptical and keeping the adaptor always attached to the 120V EVSE ....otherwise if you let the adaptor attached to the 240v receptacle ...then someone will eventually plug a 120V device into that adaptor....ouch.
BTW I have seen on this Priuschat board , poor quality 240V socket receptacle melted because some of them are cheap and not intented for that task.

 

I used a good quality NEMA 5-20 socket for my adapter cord build - No issues.

FWIW; a couple of 20A extension cords I bought years ago was heating up at the connectors. I'm pretty sure it was cheap workmanship. Cut both ends off and replaced them with a quality plug and socket - No more issues. Just a warning to check these things periodically while charging - things loosen up when your pushing a lot of amps through a cord.

 

EVSE Plugs and the sockets they are plugged into can heat up in the summer and cords can melt snow in the winter even at 120volts, when other conditions are just right.

 

Be sure to get the UL-rated version.

When this thread started, I don't believe Amazon carried products like this. Buyers had to go elsewhere, I suspect Alibaba.com had it or similar. But Amazon's standards have 'changed'.

 

for some reason the picture of said item is not working for me, any chance someone can repost or ping me direct the item?

 

Bought a whole charging EVSE $109, 28 feet long, 120v to 240 V adapter short cable, water resistance, has app for monitoring charging, and a bag. The $845 Toyota one goes in storage area in trunk, or stays at home. I think 120 v is fine for my purposes for now. Hope the app works. Vevor brand direct from Vevor.

 

Very difficult to contact and resolve an issue buying directly from this company Vevor. Not recommended.

 

FYI I rigged up a 15 amp breaker, with a 14/2 romex (had it lying around or 12/2 is better for 20 amp breaker setup), and used this adapter:

for about $40 all in and the oem charger which maxes out at 12 amps at 240v works great with it. No need to screw around with making your own anymore. Super cool to the touch on both the adapter and the romex. You can not use 14/2 romex with 16 amp chargers legally but for the 12amp continous you're fine. Charges the prius prime in 2.5 hours vs 5 hours at 120.

 

Still getting mine put in. The car charger is 3.3 kw on 240, so a bit more amps on 240, 13.75 amps on each leg. My aftermarket evse is capable of 16 amps so will use the existing 2 pole 20 amp breaker already in the panel with 12/2. Even though this car won’t need 16 amps. Wanted to return it but actually not hauling out the car evse back and forth to charge at home is not a bad idea.
The long cable to the car is #14 anyway.
