I just received my new USB pasthrough for my DSE901B and noticed that the 5 second draw cut-out seems to come on quicker than with a regular battery. Has anybody else experienced this? Could it be that it needs a break-in period? Since the cut-out seems to come on quicker I don't get the normal ammount of vapor...Don't get me wrong, it still produces bunches of vapor. Just not as much as I get with a battery.

Overall I am verry pleased with the USB passthough and I'm not complaining...Just wondering if this is normal.
