Yes It's probably the same as my Zencar but maxes out at 16a instead of 30a.
I guess if your ok with 16a, for example if you only have a Leaf with the 3.8kw charger, saving the money might be nice. I personally like the ability to charge up to 27.5a on my Leaf and would be willing to pay the extra $100 or so it would cost. Actually I custom ordered mine directly from China and was able to get a longer cord and the input plug I wanted, all for cheaper than what Amazon wanted, but not everyone is probably comfortable ordering directly from China :)

I believe I read Juicebox is working on a way to directly connect to the EVSE with WiFi but as of now it's internet only and somehow through their servers. When someone asked what happened if their servers went down, their response was they had a very redundant system, of course no internet connection, no way to change the output current as of now. Again you can use the EVSE, you just can't change the output current from it's last setting.

I think you'll be OK with 6a, EVSEupgrade goes down to a 6a setting and I've never heard of anyone having a problem with it. I believe 6a is the lowest current allowed with the J1772 standard EVSEs use.



If you are of the smartphone generation then the JuiceBox is the way to go. Personaly I do not want to use a smart app on my phone to control my EVSE.

I build OpenEVSE units with a fifteen dollar multi function meter that stores stores KWH until reset; That works for me. I just want to walk over to the unit to read it. It really depends on your generation. I just want an EVSE that is safe and works for me. Most Chinese EVSE's fail the GFCI test since that requires a lot of skill to get it to work without falsing. Most Americal EVSE's like Clipper Creek, JuiceBox and OpenEVSE pass the required GFCI test. As far as I know it is just the Chinese units.

With Chinese parts the semiconductors cost $10 or less. The discrete parts cost around $10 or less. The +- 12V module is $10 or less. The case is around $20 the multi function meter is $15 and the PCB and display is $15 or less. Cables are the most expensive item with a 40A J1772 cable and input cable at around $200 or less. Add $20 for misc costs. It really costs little especially considering I paid nearly $360 just for the Ji772 Cable. Prices have really gone down. Chris is handicapped by the fact that his supplier uses Digikey exclusively. I scrounge parts from eBay. Yes I am cheap. Since I do it as a hobby I do not consider labor costs.

Anyone have any experience with either one of these?

So many choices out there, I'm trying to figure out which portable one I should get

Your second link just goes to a selection page, not a specific EVSE.
AFA which portable to get, I personally would want one with the ability to limit output current. I guess if your always going to plug into a 14-50 outlet it wouldn't be so important but if your like me and have several outlet adapters to allow you to plug into a variety of outlets you may run into, in the wild, you really need to be able to limit the current to no more than 80% of the amperage of the outlet your plugging into. That would mean 16a for a 20a outlet and 24a for a 30a outlet, a very common amperage outlet. If you can't limit your charge current, and you have a Leaf that can pull up to 27.5a(also called a 6.6kw charger) you can really only use a 14-50 outlet or similar outlet with a minimum of 40a.
I really like my Zencar EVSE, purchased directly from China for ~$400 with a nice long(8m) flexible cord. I specified 12a, 16a, 19a, 24a and 30a(max) settings. Note I really only use the 19a setting(all settings good on both 120v and 240v) for known quality outlets fed by a minimum 12g wiring and even then for not much more than 1hr, basically for emergency charging when I need the maximum charge rate and need to get going as fast as I can.
Another good EVSE is something like an adjustable Juicebox where you can specify the maximum charge current down to the amp, I believe something like an OpenEVSE allows you to specify even charge amperage, unless they've changed something.
If you only have a 16a max Leaf or only plan on plugging into a 14-50 outlet then adjustable might not be that important.

Thanks for your reply. I don't know why it cut off the link, this may work https://tinyurl.com/y8lkcxuw

I agree on the adjustable, I do have an SL with the 6.6kW charger, so without an adjustable I could be in trouble of not able to charge by tripping breakers "out in the wild" .

I had my eyes on the zencar, but it does not seem available. There's one used option on Amazon, and on zencar website there's only "Inquiry" button, no buy option... https://www.zencar.net/product/32a-evse ... sae-j1772/

Where did you buy yours?

I looked into openEVSE too, but that's getting a bit costly, I was trying to stay under $400 for a portable option.

I looked into openEVSE too, but that's getting a bit costly, I was trying to stay under $400 for a portable option.

I purchased mine directly off the Zencar website, I emailed "Dream" and told her the options I wanted(cord length, plug, amperage settings) and she came back with a price. I paid with Paypal and it took a couple weeks to get here from China, Alozzy from Canada also ordered one and I believe was quite happy. Note when inquiring with Zencar they aren't really a retailer, more the mfg. and there is a bit of a language barrier so don't expect a polished retail environment. I mainly did it because I wanted specific things such as a 19a setting and the L6-30 plug and a longer than normal flexible in cold weather cord. If your OK with how your first tinyurl link is setup(which does now work :) ) it seems to be very similar to my Zencar and the price is good. Again what I really wanted was a 120v/240v portable EVSE and ability to adjust not only the 240v(also works on 208v, I've used mine down to 198v) charging current but also 120v. Some portables allow you to adjust 240v but only set 120v to 12a which really leaves a lot on the table if you have access to a good 20a outlet or even the rare 30a 120v outlet.
Note purchasing the various outlet adapters can add up, which is why I made mine and price and less bulk was the reason I wanted the L6-30 plug on my EVSE. Finding the female variety of L6-30 is easy and cheap(they start ~$6) while female 14-50 plugs are closer to $20 each and very bulky. To make an outlet adapter you need the female variety of the type of plug on your EVSE and then the male variety of the outlet you want to plug into and finally some good minimum 10 gauge 3 wire cord. Most of my outlet adapters cost <$20 each to make, purchasing them can often times cost >$50 but they are a bit of a hassle to make, well just takes time.
<$400 was also what I was looking for which is one of the reasons I passed on the OpenEVSE, that and most OpenEVSEs aren't the top in, bottom out, style I wanted. Most OpenEVSEs seem to be more a side in, side out style. Juice box is a very quality EVSE but as you noted, more North of $500 and the new ones require a phone app and internet to be able to adjust the output amperage, something I wasn't sure I'd have access to in the wild.

Edit: I did see one reviewer state the cord(on your linked EVSE) would get quite stiff in the cold, that wouldn't work for me in MN and I didn't see any mention of cord length. I've used every foot of my 8M cord and was happy mine was that long. I could forward me the emails I got from Dream at Zencar if you wanted, I believe I still have them, just PM me your email address if interested.

I'm definitely interested to see which options you asked for with your Zencar. I didn't know it would have been an option to get it custom made.
I've only had the car for 2 months, so I'm still trying to figure out the best (and most versatile) gear I should have in the trunk!
Sent you a PM, thanks!

EDIT: did you get my PM? ... I keep trying but it's staying in "Outbox" and not showing up in "Sent"

Yes I see it, it won't show sent until I open it, I believe.

Got it, thank you! I already contacted them.
I like your idea of getting it with a less bulky plug since there's no need for a 50A plug to charge the Leaf with L2
And if I run into someone with a Tesla that needs to charge ... they'll just have to deal with the 30A limit ;)
