Telefonix Retractable Cord L1 PowerPost Charger

L1 PowerPost

“The award winning L1 PowerPost electric vehicle charging station is the first commercial grade Level 1 electric vehicle charger with patented retractable cord reel technology.”

Provided it operates as intended (meaning the cord doesn’t jam up or resist retracting), then isn’t this the most attractive, user-friendly and clean way to manage the cord for public charging stations?

We have to wonder why more chargers don’t feature retractable cord technology.  My $100 vacuum retracts its own cord, so it’s not like this tech is expensive or difficult to implement.

The only issues we see is with managing heat of the cord if its plugged into a vehicle, but not fully extended out of the charger and whether or not the retracting system is robust enough to handle thousands of operations without flaw.

Anyways, Telefonix says that you’ll find the L1 PowerPost  “in a parking garage at Denver International Airport and in an outdoor parking lot at Rosalind Franklin University of Medicine and Science in North Chicago, Illinois.”

If you’ve used one of these chargers, then let us know what you think of its operation in comments below.

I agree this is the way to go for wired chargers. It isn’t worth (to me) the $700 extra just for the retract feature (over the $800 I paid for an AV charger), but hopefully the prices decline over time.

I would say that deploying these commercially (supermarket, work, etc) should pay for itself in not having to replace the cord as often. We have the non-retract types at my work, and the cords are everywhere, and getting stepped on and run over.


To me a retractable cord sounds user friendly, but I would be worried about mechanical failures/maintenance as this is an outdoor application.

Also I am a bit puzzled by L1… If charging is so slow would you take the effort to plug it in? Especially with the next generation of EV’s with bigger batteries, it is questionable in which situation people would actually use this


Supermarket? No. Shop for an hour and get four miles of charge. The best place is transit stations where commuters park for 8-12 hours, workplace garages and airports or college campuses. 120V charging is best for longer term stationary parking. Malls and shopping centers are best for 6.6KW L2 where substantial miles can be added in an hour.


Making a coiling, retractive cord safe means that all the specs have to be beefed up to prevent chaffing, shorting etc.

It can be done all right but it costs money.
There is a lot more juice flowing through these than a hoover, which are also rarely used outside in the rain! 😉

The best design I’ve seen is a chargepoint unit that our local Honda dealer has. The cord is suspended from several feet above the station on a pole, and so it has similar freedom of movement like you would get at a gas-pump, with a convenient dock connector when you are done. No need to wrap up the cord like with the blink or aerovironment stations.

Yes! Our local Hy-Vee has the same charger. It’s more convenient than even a reel and most likely more durable as well.


They need a gazillion of these at airports. Even a Tesla would fully charge over a week at L1.

No sense in a $7,500 L2 Chargepoint station to fill up my car in three hours so it can sit for ten days.

that was my thinking also that L1 charging makes sense at places where the car is expected to sit for extended periods of time. that would include downtown parking garages that server commuters.

the issue with airports is that, while your car will be sitting there for days, the charger will be billed in hours, so it could be very expensive. i’m not criticizing the billing model as it does seem reasonable since your use of the charger station prevents someone else from using it even though your car might be fully recharged.


I don’t believe these L1 implementations actually have a mechanism for billing. Even if they eventually support billing (seems unlikely to me) there’s no reason it needs to be set up to bill for the duration of time it’s plugged in. Most public L2 charging locations I use bill by the time actually charging the car, or by the kWh, except for Blink.

Airports can probably afford to install four of these L1 posts in place of each L2. The lack of Chargepoint (or insert your favorite carrier here…) fees alone probably offsets much of the actual cost of a parking customer using a few bucks worth of electricity. I’ve read that each time a customer hooks up to one of these major network companies they’re billed $0.50, plus the juice.

Free L1 in long term parking seems like a no-brainer for attracting customers to your lot.

it would certainly attract me to a lot. the problem with chicago o’hare airport was that the last time that i was there, their charging stations (L2 EVSE) were in the short term hourly lot. i don’t remember what the charge for using the EVSE was, but it wasn’t free. it would be great if they put L1 charges like these in long term parking since it is “long term parking”.

Good point. One of the big challenges of rolling out infrastructure is getting the best type of charging in the locations that they are best suited for. Retractable cords could work well if the mechanism is easily fixed or replaced when it breaks down.


Keep in mind that the L1 PowerPost is L1, so the cord is much smaller than a cord on, for example, a ChargePoint or Blink evse. This is a great solution for L1 charging, either in the workplace or anywhere cars are parked for many hours. The only thing more convenient would be a retractable cord built into the car.


Something else more convenient would be wireless charging. 🙂


It would be much simpler for airport lots and garages to just put in a bunch of 120V, 15 or 20A outlets and not charge for use- electricity could be provided for years at less cost than the $1495 per L1 station!


Plus they are making a fortune for you parking there. At say $10/day, if you charged a Tesla say 70kWh @ 12cents/kWh, it would take a week but the first day would pay for the $8.40 of electricity.


That assumes Tesla drivers always end up at their charging location totally empty. I bet many drive from home to say their local airport 50 miles away and are not totally empty. Recharge in a day or less. Even 120V airport spots will be not-charging most of the time. But still better than installing only a few higher priced J1772 L2 spots. They need to quadruple the spots at my local airport, BWI. There, only four out of the six are usable as they keep closing the top floor where there are two stalls.


Many EVs do not have a mechanism for locking the EVSE to the car (The Leaf and the i3 being the exceptions).

I don’t know about you but I’m not too hot on the idea of leaving a $500 cord unattended in a parking lot for a week or ten days.


Here is a wonderful concept


Chargepoint CT4000 has had the retracting cords thing, but this is the first L1 that I have seen. Since the installation cost can be the biggest part of the cost, if making them L1 makes it cheaper to do en masse, I am all for it.

I think the ideal solution is a smart grid of L2s that reduce power when all are used, but a parking lot full of L1s has many useful applications, workplace charging being the most obvious.
