Slim Level 1 Charger

[jfn12587]

I park my Taycan on a street in Brooklyn with a busy sidewalk. I sometimes have access to a regular outlet at the curb so was considering trickle charging just to top up. But I'm worried about 1) the J1772 handle sticks out pretty far from the car, and someone or something might bang into it breaking the charger or the charging port, and 2) most L1 chargers are pretty bulk with long, thick cables that I'd have to tuck away somewhere.

Are there any L1 chargers that use a different profile connector? I'm thinking along the lines of a right angle plug adapter. Preferably with a relatively small charging unit. I don't need L2 charging at all, just 110v at 15-20 amps.

It’s probably a 5-15R and limited to 12A charging, not 15-20 amps. Probably 3-4 miles an hour after losses (just a guess).

Porsche recommend "emergency" use of L1 charging only…

from the published tech article - note these are Porsche's words not mine or the internet - the manufacturer of _YOUR_ vehicle does not recommend doing what you want to do…they haven't provided any exact reasons, but only the guidance.

General Precautions on (125V) Supply Cable Use
The “domestic” (125V) supply cable is provided for emergency use only, and should not be used by customers for daily home charging. Please discuss installation and use of a suitable 250V circuit with all customers.

that being said the Tesla Mobile Gen2 EVSE is the best $200 mobile EVSE on the market and it has L1 adapters - it's small, light, rugged, flexible, high quality, reliable.

the Tesla Mobile Gen2 EVSE comes with NEMA 5-15 adatper, and has an optional NEMA 5-20 adapter - you'll need a TeslaTap or equivlent to use it but you should have one of those anyways and it's useful for general travels.

but that being said porsche does not recommend using L1 charging - they have never been clear as to exact reason, but informed speculation is that running the car's charging infrastructure for hours on end at only 1 to 1.5 kW stressed the MTBF of various component - so honestly it's not recommended use case.

I meant that the outlets are likely 15 or 20A max, meaning that yes 12A would be likely. Given the car will stay stationary for a day or more at a time I don't mind slow charging.

My read of that safety thread is that L1 charging with the mobile charger is bad, not that L1 charging in general is bad.

I didn’t find anything googling around. All of the handles look pretty standard to me. There could even be some standards on the handle. I don’t know.

I would suggest you re-read the recommendation:

yeah I'm pretty sure that's not what they are concerned about - but I agree they are non-specific - it's your car…but there is so much overhead keeping the various electronics "on" while the car is charging - that I'm pretty sure it's the accumulated runtime hours given how slow L1 charging is…but you do you.
