True cc/cv is better, most of the cheap chargers do not use cc/cv or it is a ruff form of cc/cv.
Ordered mine form DX 09/05/12. Received 10/10/12.
Mine also came with USA power cord only. There was smoke on my first charge, probably from grease. Disassembled it and cleaned everything, it’s working ok now. It runs hot until battery reaches ~3.5V, then it starts to cool down. According to my DMM it’s charging at 1.22A.
I just tried testing current on anything for the first time. I'm not happy.
The TR-005 from Manafont is doing 0.79A.
The TR-005 from Fasttech is doing 0.85A.
This is a lot lower than the claim. Would someone test their charger so I have results to compare against?
I used HKJ's method called "Charge current" near the bottom of the page. Notable variables/differences: Aluminum foil came from a disposable dish. I'm using the leads that came with the multimeter, a Mastech MS8268. Batteries were brand new King Kong flat top ICR26650's from Fasttech. Initial voltage for the cells in the chargers from Manafont and Fasttech were 3.80V and 3.81V, respectively.
Here's his image that I replicated.
Try starting with empty cells.
The described method has some voltage drop and the charge current will be reduce earlier with the measuring circuit added.

So, the 3.0v setting could be used to charge Lifepo4’s, yes?
