Hi all,

A quick community service announcement: Earlier this year I got contacted by a Chinese company called Ovartech, whose website lists a range of chargers and DC/DC converters for electric vehicles. I couldn't find any independent reviews of the company or their products on Google, but thought I'd risk it and ordered a sample of their 1kW DC/DC for evaluation.

I placed the order on 31st January, paid for it on 2nd February, and as of 31st March am yet to receive it. So I would advise against ordering from this company until we have more evidence of their legitimacy. Hopefully this forum page will show up if anyone else out there finds themselves looking for information on this company before committing to an order.

If I do eventually receive the order, I will be sure to update this thread and provide an honest product review.

Interesting...we just ordered a charger from them yesterday as well...will also let you guys know if it shows or not.
We haven't gotten ours yet, but Frank is staying engaged with us and asking technical questions like what we need for CAN specs...will update as things unfold.

Update: The charger was ridiculously late, but it DID show up, just now. Frank said he had problems with his tooling.

Haven't tried it yet but it looks nice enough...
Hello all, I am Frank from Ovartech, we admit that we had some problems before on lead time, finally all our buyers received what they paid for.

Thing are getting better now, basically we have inventory for our hot sellers, for example:
3.3KW charger in 108V, 144V, 360V
6.6KW charger in 360V
1KW DC-DC converter in 360VDC.

Anybody who are going to order from us, please check with us the inventory before you issue a purchase.
Thanks for sending the charger, Frank.

If you are interested in expanding your product line, you may wish to consider a 700VDC nominal (800VDC peak) charger. Quite a few people are moving in that direction to get more performance (and the new SAE DC fast charging standard now supports it). But currently there is only one 800VDC charger on the market and it is extremely bulky and extremely expensive. So if you were to develop an 800VDC charger similar in size and price to your current offerings, I think you would find little competition.
