Declared data 3,3/3,7//4,2 volt - this facts are wrong. Actual data (with power source 5 volt 5 ampere): w/o loading - 3,96/,3,58/3,15 volt; with loading 1,7 ohm - 2,72/2,45/2,17 volt; with loading 2,3 ohm - 3,3/3,0/2,6 volt; with loading 2,8 ohm - 3,65/3,05/2,65 volt. Too strong a voltage drop, too poor vapour.
You can lay claim for manufacturer.
