Charged Mr CT for first time last night on the mobile charger adaptor plugged into my 14-50 recptical. It charged from 47% to 80% in 5 hrs and 40 min. The 14-50 has a 50 amp breaker, 240 v, and charges at 32 amps. Converting to miles, it charged from 151 miles to 257 miles, or 18.7 MPH. Using the percentages and current battery miles, produces a battery range of 321 miles. My Model 3 (with 74 kWh battery) on this 14-50 charges at about 35 MPH. I believe this charging was as expected.

I connected to a Chargepoint using the J1772 adapter yesterday at Whole Foods, it was a disaster lol. Two of the three stations were broken, and the 1 working station's screen was completely opaque from sun yellowing. I never got it to work.

Fun fact, you should remove the charge cable and adapter simultaneously. A broken CCS cable will let you leave the adapter in the charge port, and removal triggers the cover to close. ?

I've Supercharged at 250kW, 72kW, and L1 charged (120v/12A) at home. Still trying to get 3rd-party charging to happen.

Are you using PlugShare? It has a rating for locations and is crowd-sourced and pretty accurate. It should have shown the site with a low reliablity and you can add that you weren't able to charge there.

I have a Gen 2 and and gen 3 wall charger. My Y and 3 charge at 48a on both chargers. The cybertruck 24a on both. Have a service request in. I suspect the inverter.

Do you have a destination charger nearby that you can test on?

No, but I charged at 2 different generation chargers at 2 different locations with the same results. They are identical to destination chargers. I have 3 other (now 2) S100d and new 3. That charge fine. My suspicion is this is sufficient to tell me it is something with the truck Either a software bug at an inverter issue

Today was the first time charging my CT at home and it’s refusing to charge at 48a. In the charging settings I have it set to 48a but once I plug in it automatically drops and charges at 24a.

Anybody had this issue? Could it be beac it’s the first charge? I have a model Y and never had this issue. I’ve tried everything I could to troubleshoot. TIA

Are you using a Gen 1 (100 Amp) Wall Connector? If so, try changing it's switch setting to a 60A breaker.

I just started experiencing this same issue. I’m scheduled for a service appointment to have it investigated. Did you ever get this resolved? What was the root cause?

I put in two 240v receptacles (a 14-50 & 14-30) to charge using the portable chargers that come with a vehicle. The 14-50 receptable will charge at 32amps max, and the 14-30 receptable can only charge at 24amps max, which is what they are designed for and the Tesla's are smart enough to only allow those maximums.

over the weekend, my cybertruck started having the 24A max issue. wall connector is provisioned at 40A because circuit is a 50A circuit, model X draws 40A no problem. Tried 32A PowerShare mobile connector, CT limited at 24A, model X draws 32A. still able to charge at 24A fortunately. doesn't vary with ambient temperature and the cable and the plug are not not at all.

The error I see in service mode is "PCS2_a136_cycloAMosfetHealthCheckFailed" so I assume the onboard charger is the issue. service request placed

The onboard chargers have segmentation inside them (so they can do different levels of charging) so if one of the parts fails, it won't be able to charge at full.

So yeah, definitely something that needs fixing!

My issue was resolved during my last service appointment.

My issue ended up being the same as @e90n54 : they replaced the "POWER CONVERSION SYSTEM - 48AMP(1777777-12-E)" and now it goes back to charging up to 40A on my home circuit. Took them a week and a half to diagnose and repair--the longest I've ever had Tesla work on one of my cars!
