These finally shipped! I bought this for a speedy charge solution for my InMotion V12 when on the go. it's a chunky boy, coming in at 1544g. The OEM V12 charger is 936g. It takes up 1474 cc. The OEM V12 charger takes up 1049 cc. That's a 65% increase in weight with a 40% increase in size. It's loud. The fan is audible at every charging level. All that active cooling hardware generates more noise and adds weight. I like the power meter, which provides real time voltage, current, power, amp hours, and watt hours. I think overnight charging will still be handled by the OEM charger which is silent but this is a good option if you're on the go and need 4x the charging speed.
