Not trying to change the subject, but here is a question for you guys.
Ok, I ordered a MFLB power adaptor. It came with a switching adaptor, (wall-wart), with an output of 12vdc 1250mA. In use, (with rheostat on max), the light in the MFLB blinks. Which means it is pulsing. If turned down it stops pulsing. When using the auto adaptor, (using a fully charged jump-start battery as a power source), it doesn't pulse.
Contacted MFLB customer support, they quickly sent me a new "wall-wart", (output 12vdc 2000mA). Had the same outcome. Both wall-warts actual voltage @ the battery simulator was 12.2vdc. The auto adaptor output was 12.8vdc. The incoming AC to the wall-warts was 122.3vac.
The actual output voltage on both w-ws and the auto adaptor is 1.9vdc max rheostat. and 1.1vdc on min rheostat. I know it's pulsing because it doesn't heat up well with the w-ws but does on auto adaptor.
I know the lower temps have better flavor, but the higher temps put me to sleep @ bedtime.
I have learned so much from everyone on FC, I thought I would pick your brain. Dynalowrider
