Hi, sorry if this has been posted and discussed. We own a 2022 Cayenne hybrid. We love it, done about half 50 000 km on full electric. In March of this year there seemed to a recall on the charging units and the charge wire (charge unit to wall wire defect). Porsche keeps telling me there is no update. I finally called Porsche Canada only to find out we can order a temporary replacement charger (max price $600.00). Does anyone have experience or model types that work. Porsche suggested the Juice box 32 smart EV charging station. Taycan owners received Grizzl-E chargers. Any help would be appreciated.
In particular, this post from that thread should be helpful:

If you choose to eschew the included Porsche EVSE there are numerous high-quality affordable alternatives - and again all will work with you Hybrid/EV to charge them - they are all universal by design…
a partial list of alternative EVSE's are listed below - many of these have been in use by EV owner's for years and well understood, compatible, affordable, and deeply reliable:
Tesla Universal Wall Charger - 60 amp max power, NACS/J-1772 compatible - bulit-in adapter, WiFI, OTA updates, app, charging stats, multi-EV shared power load charging support
ChargePoint Flex - 70 amp max power, NACS or J-1772 swappable cable, WiFI, OTA updates, app, charging stats
WallBox - 60 amps max power - WiFI, OTA updates, app, charging stats
Porsche Wall Charger - 100 amps max power - WiFi, OTA updates, app, charging stats
Enphase/clipperCreek - 80 amp max power - simple, reliable, bullet proof, no fancy features
JuiceBox - great choice, many many people love their juice boxes

Thank you
_ANY_ EVSE (EV charger) will work for you - I'd suggest getting a 40 amp (50 amp breaker) EVSE since that's what your Porsche unit is - this will set you up for your eventual Macan EV or Rivian etc…
On a related note, to charge a hybrid from a NEMA 6-20 socket (all I have until the new garage is built), do I need to buy one of the chargers above or is the mobile charger provided with the new hybrid sufficient?
you'll need an EVSE that supports 20 amp breaker setting…16 amp maximum charge rate on a 20 amp breaker is "the rule"
NEMA 6-20- is 240V @ 20 amps on 20 amp breaker
EVSE's in North America are considered continuous use devices, which means they are only allowed to use 80% of the rated capacity of the circuit - so a 20 amp breaker means you need to only draw 16 amp of actual charge current.
240 volts * 16 amps = 3,800 watts or 3.8 kW
the new Cayenne comes with a 25 kWh battery AFAIK - so 25 kWh / 3.8 kW = 6.57 - so it will take 7 to 7 1/2 hours to charge the new Cayenne from empty on a NEMA 6-20 outlet…
Porsche does not sell/offer a 20/16 amp charging cord for North American market (16 amp charge rate) - Porsche does not offer a NEMA 6-20 power supply cable *
so of you have the Prosche Mobile Charger Plus (PMC+) (no LCD screen) there is no "setting" on the PMC+ to dial it down to 16 amps
if you have the Porsche Mobile Charger Connect (LCD screen) there is a setting page where you can manually adjust the amp settings for the PMCC - you could set this to 16 amps each time you use the Unit
if you do NOT adjust the amp settings the PMC+/PMCC will request/pull the normal max amps settings and constantly trip the NEMA 6-20's socket's circuit breaker
You will also need some sort of adapter cable from a NEMA 6-20P to NEMA 14-50R (male to female)
_OR_ you can buy a Tesla Gen 2 Mobile Charger and the NEMA 6-20 adapter cable and a Tesla tap - and it will "just work" at the proper 16 amps for charging you Cayenne
* - for most EVSE's including the Porsche offering - the power supply cables are "smart" in that by swapping cables on the unit you are not only adding the proper plug type to the unit , but the cable also "informs" the PMC+/PMCC unit as to the maximum amps associated with that type of plug - if you have the NEMA 14-50 Porsche power supply cable plugged in the unit "knows" it can draw 40 amps, if you swap the cable for the Porsche NEMA 14-30 power supply cable the unit "knows" it can draw 24 amps - if you swap the NEMA 5-15 cable onto the PMC+/PMCC (North America household outlet) the PMC+/PMCC automatically sets maximum amps to 12…if you don't have the "right" cable attached to the unit it will set it's max amps to what cable you do have attached to the unit - it has no way of knowing you're using an adapter usurping the settings of the attached cable.
so getting the porsche unit to "work" with NEMA 6-20 outlet requires a few things:
NEMA 6-20 adapter - which porsche doesn't sell but if sufficiently motivated you could probably come up with combination of adapters from Amazon
"dialing" down the unit's maximum AMPS to 16 amps - no real way to do this with PMC+, you can directly do it with a PMCC unit - if you don't do this the PMC+/PMCC don't "know" they are plugged into 20 amp outlet and will draw max power, causing the breaker to trip after a few min of run time (or melt the wires and cause a fire if the breaker doesn't do it's job).
remembering to set the AMP settings each time you use the unit - since it will 'forget" your setting if you unplug it or it resets overnight
Tesla Universal Mobile Charger Gen2 w/NEMA 6-20 adapter will do it + TeslaTap
Mustart EVSE with NEMA 6-20 adapter will also "just work"
this adatper will allow you to plug in your NEMA 14-50 EV charger to a NEMA 6-20 outlet - but it will _NOT_ adjust the PMC+/PMCC units amp settings down to the required 16 amps - since the factory/OEM NEMA 14-50 cable is still attached to the PMC+/PMCC unit it will blindly and wrongly assume it can draw 40 amps - best case this will cause the breaker to trip - worst case the breaker won't trip and you'll melt the wire associated with the 6-20 outlet and cause a short circuit and potential fire from the melted wire.
On a related note, to charge a hybrid from a NEMA 6-20 socket (all I have until the new garage is built), do I need to buy one of the chargers above or is the mobile charger provided with the new hybrid sufficient?
since the Tesla unit has a "native" NEMA 6-20 adatper cable (unlike porsche) the unit will always draw the correct number of amps when plugged into a NEMA 6-20 outlet.
since Porschde does not provide a "native" 20/16 amp power supply cable it's a bit of jury-rigging exercise to adapt/trick the PMC+/PMCC into charging at only 16 amps.
The Porsche Wall Charger is a non-mobile hardwired EVSE with adjustable amps settings (12-80 amp charge rate) - it would be a simple matter to "hardwire" a Porsche Wall Charger to your NEMA 6-20 outlet and then use it's built-in configuration settings to fix it down to 16 amp draw rate - $1670 - https://shop.porsche.com/us/en-US/p/...B&gclsrc=aw.ds
Also ChargePoint flex or Tesla Universal Wall Charger also can be adjusted to "any" amps - setting the units to 16 amps from your 6-20 outlet/circuit - both of these are $700 or less - and can be natively configured to only draw 16 amps once wired into your outlet/circuit.
if you are handy with household electrical work it's a very very simple matter to take a 6-20 extension cord and wire it to the Porsche Wall Charger, ChargePoint Flex, or Tesla Unit and then set any of those 3 EVSE's to max power of 16 amps to match the requirement for your 20 amp circuit.
the PMC+/PMCC are not the best tools for this particular job given they lack of native support for a 20 amp supply circuit.
or you can use the money you'd spend on alternate EVSE solutions to pay an electrician to install a 50 amp circuit and then use the PMC+/PMCC that comes with the vehicle - this has the advantage that it will charge your Cayenne about 3x faster (40 amps vs. 16 amps) - making turn around time to charge the Hybrid less than 3 hours - and you'l be set up for future EV's which have bigger batteries and would take even longer to charge off a 6-20 16 amp circuit.

Thank you! It's a bummer that Porsche does not have the correct adapter. I'll get a Tesla or other mobile charger that works with NEMA 6-20 then. Getting to full charge overnight is good enough.
