Reviews

The charger is very close to a CC/CV charging profile. The charger does charge to a little below 4.2 volt, this might put slightly less energy in the battery, but will increase the lifetime of the battery a little. Because the charger does supply a small current at 0 volt, it can reset any kind of protection. The possibility to select two charge currents makes it much better for both 18650 and smaller cells, the 18650 can be charge faster and the smaller cells can be charged safer.
The usb power is a nice addition, but would have been even better if it always worked when 12 volt was connected to the charger.
All in all a good charger and a nice upgrade to the old WF2 charger. ----- HKJ
