This charger uses automatic voltage detection of PD2 & QC3 USB-C protocol between 5, 9 & 15V at 3A that are capable to charge 2 Li-Ion batteries at 4,1A (8,2A summary) and it needs at least 45W PSU and USB-C output. The use is strictly the automatic fast charging of high current Li-Ion with no fancy tests or discharge modes , either user interference except current settings. Initially it automatically measures batteries internal resistance and decide the current level that each battery can handle and meantime current sensors will decide if later a current downgrade is necessary for each battery safety. The only charger in the market for quick charge of high current batteries at 4,1A.

Works on my 45W output battery bank and 60W wall charger. No problems. Everything it says it can do. Works with my long protected 21700 batteries. Very fast. Switch to 1A toward the very end for a bit more juice/full top-off; other than this it is perfect. Five Stars. REALLY NICE TOY!
