The original costs about 120€, china clones begin at 10€.

The Saleae software for windows only allows their original hardware by setting the VID (Vendor ID) and PID (Product ID) in the saleae.inf file. This file is required as driver for the harware.

iMax B6 charger (and clones)

There are various variants of this charger available (dual/quad output, 12 or 230V input, 200W version ...).
And also some clones, be aware, most clones are not calibrated -> poor balanced cells and overloading can happen !

An open source replacement firmware is available github.com/stawel/cheali-charger.
This allows calibration unlike the stock firmware.
