JLong is the perfect compliment for any EV that needs to charge. JLong can extend the length of the charge cord by 5 to 40 feet.

It helps when you're at a public charge station and it's blocked (but you can get into a nearby spot). Instead of frustration, just park nearby and use JLong.

You don't need to know anything about volts or amps. No technical knowledge required. Just "Plug-N-Charge(TM)"

JLong is for those charge stations where the cord won't easily reach the back of the car. Or, for those visits to somebody's house to charge from the dryer electrical outlet or other home wall outlet using your own (always too short) portable charge cable.

It works at long term airport parking, so that you can park in an adjacent (non-EV) spot and get fully charged without blocking out the dedicated EV spot for a week or two. Just lock the JLong to your car and leave a note when your car is done charging.

I use JLong a lot around the house when another car is blocking my charge spot, or when I park in the driveway but still need to charge from my garage mounted charge station.

You are fully protected by all the safety protections of J1772 (proximity disconnect, ground fault, pilot signal, etc) with JLong. Plus, it's fully 40 amp capable, light weight and very portable. One of our top sellers.

JLong works with EVERY plug-in car sold in North America, and EVERY J1772 / L1 / L2 charge station (Type 1 in Europe).

It's not if you need JLong, it's when.

JLong vs competition

With the JLong(tm) premium J1772 extension, we started by designing the very best cable for the job, not by using existing cables designed for EVSEs, and we have those cables built in California, USA... not China.

Since we pioneered this niche product, there are now at least two others available, both using preassembled Chinese plugs and cables that were intended for EVSE charging stations only.

We recognize that there's always a market for the cheaper product, but unfortunately we won't use products that don't meet our high standards:

1) Our JLong is the only J1772 extension that gives you 100% of the protections of J1772 (proximity disconnect, ground fault, pilot signal, etc). I personally think it's absolutely critical not to substitute lower price and quality for safety standards. Others may claim that they follow all J1772 protocols, but only JLong(tm) does.

The Chinese cables used by competitors do not carry proximity detection at all. The reason that they can't do this is because the cables don't even have the wire inside to perform this critical task. That means that every time you disconnect the J1772 charge station from the extension while the car is charging, there will be a "hot" disconnect which can damage equipment and cause a spark / arcing. Not my idea of a smart or safe design. Sure, they might put a sticker on their unit to tell you how unsafe it is, but the fact remains that you can physically disconnect it while under load. Dangerous and dumb, and something we would never offer for sale to the public.

2) Because we build our own cables in California, USA, we can and do make improvements all the time. First, all the power wires are doubled... instead of only two, we have four parallel power wires in the cable. This allows us to build an ultra light weight and super flexible cable. Secondly, we include all the communication wires necessary for safety. There are actually 8 conductors in each of our cable assemblies. The Chinese cables use half that. We offer both 40 amp continuous and also 80 amps. The competition all uses 32 amp or less.

3) Chinese cables are HEAVY and clunky, and not very flexible. We don't even offer them as a resale item with our EVSE cable/plug assemblies. Our premium J-Plug(tm) uses the same cable as JLong(tm).

4) At least one competitor was soldering his wires to the power pins. We absolutely have NEVER done this. All of our connections are crimped to aerospace / mil-spec standards using commercial air powered and calibrated tooling, dies and locators. We have never had a failure of these parts. As you might imagine, failure in this area can burn your car or house down. We recently learned of a homemade charging station wiring job that caused almost $3000 in damages, and this was a VERY experienced hobbyist. Please don't compromise safety or your home.

5) The competition doesn't use a handle at all on the inlet end. NONE. There is a cheap plastic "dust cap" that I can compress with my fingers. Our inlet handle is built from 6061-T6 aircraft grade aluminum alloy, cut on a water jet, and TIG welded. Then, we powder coat with a slip resistant finish and laser etch our logo. You can DRIVE YOUR CAR OVER OUR HANDLE and it will not crush. Since these are designed to lay on the ground, this seemed like a smart design requirement to us.

6) With 40 and 80 amp capable equipment built to the highest standard, every known J1772 vehicle in the world can safely use JLong(tm). Tesla Model S/3/X can also use JLong with the Tesla adaptor supplied by Tesla. The Tesla Roadster, as well as Model S or X with "twin chargers" or 70/72 amp
onboard charger will require the 80 amp Jlong(tm), or limit the power to 40 amps.

7) Again, because we build our own cables, you can get JLong in any length you like. Believe it or not, 40 feet is the most popular (and we have custom built longer). The Chinese cables only come in 25 feet or less.

Here are some of the industry articles written about JLong:

Ah, yes, but not right now. I'm completely swamped. Maybe in a week or three.

I've seen these on ebay from time to time. There's one now but it's probably a bit overpriced and only 10'.

If you ever consider building a 40 amp version I'd buy one. My CS-60 may melt this one. I have to back into the driveway to charge my Rav4 and sometime my Leaf is too far to charge with both in the driveway.

Rather than attaching an extension cord to your CS-60's cable, why not replace the cable entirely with a custom-made replacement of any length you choose? Replacing the CS-60's cable is a job you can easily do yourself, and you can probably get a couple hundred bucks selling the old cable.

I want it for dual use (home and blocked public chargers). Plus a constant extra long cord would be a hassel (I'm lazy). I look at it as insurance (like Tony's UMC that I've never used yet but want to have it when I do). I expect to have EVs for the rest of my life and I look at this like a lot of the expesive tools I buy that I seldom use but really enjoy when I do.

If no one builds a 40amp version I may get this one and also use your sugestion. Thanks.

The 6 gauge cord that fooljoe linked is grossly heavy and overbuilt for our 40 amp chargers.

I will tell you that I have used the 20 foot long JLongtm that is built with the smaller and lighter wires of the ITT "30 amp" rated cable... it does not get hot. I am comfortable using it at 40 amps.

I certainly can build a JLongtm with the bigger, heavier and more expensive cable, but you won't like carrying it.

I agree, but the seller I linked to is the only source I know of for a custom-length cord. Another option is this 23' 8 gauge cable sold by Sustainable Solutions Partners. If you have one of the refurbished CS-60s they sold on ebay this is the cord from it. Unfortunately it's still a pretty bulky and inflexible cord, but 8 gauge is the "correct" gauge for 40 amps.

I also agree with Tony that you'll probably be fine "overclocking" a quality 30amp cord - just make sure you monitor how hot it gets the first few times you use it.

I should point out that another solution, especially since you're apparently already carrying around one of Tony's Jesla UMCs, is to just get one of these J1772 to 14-50 adapters for occasional use. This will effectively turn your Jesla into an extension cord.

That is a several generations old Dostar plug (I won't use them) with a 4 conductor cable. It will not pass through the proximity signal, so I won't use those either.

The ITT 30 amp plug and cable assembly is a quality product that is currently on sale.
