I got myself one of these chargers. I bought it from eBay though. It was 25$ + shipping which I thought isn't bad for a single cell charger.
Here is a link to the product

and eBay auction
http://www.ebay.com/itm/Charger-Single-L...5805818417
Product ID is the same on both sites (JCSC10). Even product description is copy-pasted to eBay. I believe it is the same guy/company behind sales in both sites.
Then the main thing: product description doesn't match with real product. It seems to work but doesn't really do CC/CV at all. It starts at 10A nicely but amps drop soon as voltage rises a bit. When voltage is at about 3.5V charge current is less than amp and charger "finishes". I thought CC phase is 10A until voltage is 3.65V (or whatever set voltage level) and then amps start lowering when it is CV phase.
I opened the charger and it seems 100% analog. At least I didn't spot any ICs on circuit board. It has a small single cooling fan which is pretty noisy.
I thought I'd post my experiences here. I've tried contacting eBay seller and Chennic via email but haven't received any replies.
Does anyone else have this chager? Does your unit work as it is supposed to?
