Received very fast, great. but the product picture does not look anything like the one I had just received that received so long and rectangular: 83 mm Width: 45 mm and thickness: 23 MM if it is a 4400 mAh, small leaflet in French and comes in a nice cardboard box instead (ISTICK SUB OHM 50W) the name on the box. with a USB cable and charger 220 V (5V 1A) for charging the device plus a small adapter to change the output thread. now see in the time since received today! personally comfortable to hold in hand and more attractive for purposes of voltage control (2 to 10 V) and W (5 to 50 W) on small OLED screen. full charge in 5 hours and can use it to vapoter when charging. (Lithium). no regrets for having made as great battery
