I was looking for a cheap option for an emergency EVSE to keep in my trunk and figured that Alibaba might have an answer for me. I contacted a few vendors with Duosida branded EVSE units, but this one got back to me really quick.

I contacted them on September 22nd and the gave me a quote with shipping of only $145 USD. Sounded too good to be true, but also not too much of a loss if its a hunk of junk.

Just on Monday the actual unit arrived and I am going to give it a try when I get home from work tonight. Here are some pictures.

Good to know the real price of these things. I may get one to test / take apart.
 
People could make a pretty good quick buck by organizing a group buy for one of these and charging $100 in markup... Imagine what the manufacturer pays to build these things. I bet they are still making a pretty penny on the $145 or else its not worth selling to US customers at that rate.

I'm for sure going to have one of the engineers where I work take a look at it with me when our workload calms down, and I will post pictures when that happens.
 
someone is already making $150 on it

Actually what I like about it is it's also rated for 120v :)
Many other of the cheaper EVSEs are only rated for 240v(L2) requiring you to not only carry around the L2 EVSE but also your factory EVSE. When testing could you also verify this works with 120v? From the online photo it looks like your EVSE comes with a standard 120v US wall plug, is that the case :? If so the first thing I'd do is to cut off the end and install something like a L6-30P or maybe a 6-20P if thats what you have for a 240v outlet, whatever you do, don't wire 240v to a 5-20 outlet :eek:

I purposely bought this EVSE as my emergency keep in the trunk unit, so I specifically ordered it with the standard plug. There are all sorts of options that Zencar will give you. I did test it to charge my leaf all last night and it worked just as well as my standard EVSE on one of the 120v outlets in my car port. I have still not setup any 240v there, but if all goes well I might get a second Duosida for that purpose and do a more permanent install at home. The majority of my charging is done at work on their Bosch L2 units for free!

Cool, just remember it probably draws the same 16a as 240v so don't plug it into a 15a circuit or use with a light weight(less than 12G) extension cord :)
Personally I use a L6-30p(240v 30a) plug on most of my EVSEs and I've built several converter plugs to allow me to use them on various other outlets, including to the standard household outlet. I would not suggest going the other way, that is making a converter plug to go from a 240v outlet to a standard 120v household outlet. While it would be OK for dual voltage EVSE use, you wouldn't want it falling into the hands of someone who didn't know and might try plugging it into a 240v outlet and then try plugging some other 120v only device into it :shock:
 
I agree that the 30 amp twist lock plug is the best if you want to adapt it to other formats. Its simply the most secure. I will keep in mind that I draw 16 amps all the time with the Duosida. The next one I order will probably have a twist lock style plug, but first I need to add the new circuit. Actually I just need to re route my range since I have a wolf gas range with old school pilot lights and no need for the plug there. This will of course be an undertaking and it's not going to happen anytime soon.

So far so good with the Duosida, I'm using it at home again tonight. I'll probably use it for the next few weeks as my main EVSE at home, then properly mount my Nissan one when I have TIME.
 
I do a lot of business with suppliers on Alibaba, but a EVSE from an unknown supplier would be a little sketchy for me from a safety standpoint. I am new to the EV community, so is this brand a respected one?

Duosida is probably the most common out of china branded EVSE. If you see a cheap EVSE on amazon or on the forums its often that brand. Are they good? I think that is still up for debate, but I've been using mine everyday now and it has consistently been working.
 
I don't see any purpose in a group buy- just order one. They have a minimum quantity of ONE. If you achieved a $15 discount for ordering 20, you'd still have to redistribute them at a shipping cost of $15 each.

Reselling for a profit, now that makes sense. But, you're going to find lots of sources doing that, so your profit margin will be squeezed.

Exactly!
 
That shipping cost is great, I typically pay $50 just to have a <1lb item get sent to me via DHL from China suppliers so to get this $145 shipped is great.

What shipping service did they use, how long did it take?

Did you order off of Alibaba or via the seller's site?

You got a 16A one with a "normal" 120V socket, correct? Did they offer a 30A one with a 14-50 NEMA plug for 240 service? Would this replace the need for a $500 Juicebox?

Thanks for the tip.

Don't know your other questions but this is a 16a EVSE, not 30a+ like a Juicebox. Now it sounds like they may offer to put a L6-30 plug on it but it would still be a 16a EVSE.

I chose UPS Worldwide Express, they shipped it on a Thursday and I got it the following Monday.
I contacted the supplier via Alibaba, but they sent me a quote over e-mail and I paid it with Paypal.
It's 16 Amps, 110 - 240 Volts. You can get whatever plug you want.
They sell a 30 amp wall mounted EVSE that would have the same function as the juice box.
The person that I contacted was Amy at [email protected] . I'm pretty sure she would be glad to help you get the right product for your home.

6A-32A adjustable EVSE

EVSE adjustable: 6A 8A 10A 13A 16A 20A 32A
Protection class: IP54(in mated conditions)
Constant Updates Added With New Features
Work voltage: 110V~240v
Accept sample,delivery time 3-5 days.
Accept product customization

Need to see if they will put a L14-30 on as the plug.. also how long the wires are.. I have emailed them this morning..
 
^^^ interesting, looks a lot like the case of my Ebusbar L1/L2 16a EVSE. I'd be interested to see how the current is adjusted, I've seen similar cheaper EVSEs(one from Khons?? comes to mine) where to adjust the amperage you have to "shake" the EVSE :? if so that seems a bit hokey to me, hopefully it will be a software or bush button type of adjustment, can't see the "shaking" thing working too well.

6A-32A adjustable EVSE: Can select only 3 charging rates by shaking the EVSE!!!


1. 14-50 plug one end other end J1772
2. 16A 20A 32A only
3. 8M of total cable length. The unit price is $295/pc
4. Shipping cost UPS $66 usd.
5. Paypal payment

Total Price = $361
 
^^^ very decent price for a 32a EVSE....just not sure how much confidence I'd have in "shaking" the EVSE to change current on a device that could potentially draw 32 amps :?
Also it would be nice if the device also included a 12a setting so a person could use it on a standard 15a N. American circuit. With 16a as the minimum you'd still probably want to carry around your OEM EVSE in case of emergencies and you only had access to a 15a circuit :)
Someone else also posted a link to a ebay seller who sold the Khons?? 32a EVSE(probably the above EVSE) for $399, Amazon has it listed for $499 so I imagine various people are purchasing something like above in bulk and just reselling it for various profits.
$399 https://www.evseadapters.com/en/for-evse-upgrade/132-new-16-30a-adjustable-120-240v-charger-evse.html
