MIne Has the Firmware that came with it. I will check this out, I have a Silver one that came with the original and It is really outdated so to speak, I should see if a Repair person could update them.... I have been using that nano tank since last night and the juice level has barely changed That's kinda refreshing I have mine set at 20 watts on my older ones I use. A Beauty ring so the look more Modern but those are volts only .
