Since I added the smoke generator, I got an adapter from Amazon to allow the Bella air pump to be powered directly from the Auber’s smoke generator output. This eliminates the need for multi plug adapters on the 117 AC power cord. This is a programmable (R) output, so be sure to enable it. This has probably been posted before, but thought I'd share it just in case.
