Here's some info from other sites:
ok so at 80w its reading 3.25v on meter (T8 reading 4.3) [.23 ohm ] so thats 5 raps 2mil 24g micro
100w 3.26 volts
150w same 3.26
NEW BUILD------
Put a dff atty and its reading 4.3v at .3ohms
mmmmm 61 watts box showing 70watts
100watts----4.55v
150watts ----4.55v
mmmmmmmmm
looks like a 65-70watt box mod,thats sad
let someone else test it,but that looks right-give or take
Just a thought:
They maybe were trying to make a 150w chip and have a 14v output - but it may have been a fail
This must be (my thoughts only) the T5 50 watt chip with the upgrade to 75watts (but its working and not blowing up the chip like 16th sept)

The published spec says it has a 7.4V and 20A limit on its output. You'd actually need about 32A to get 150W at the minimum resistance of 0.15Ω.
With a 7.4V and 20A limit you should be able to get full power at about 0.365Ω. Any higher resistance and you run into the voltage limit, any lower resistance you run into the current limit.
At 0.3Ω you should be able to get 20A @ 6V and get 120W. If you are only getting 4.55V, it sounds like it may be limiting the current to 15A instead of 20A. That is not meeting the published spec, however weak it is.
Man, these guys are really playing a game with these specs. They are totally ruining their reputation, worse than it already is. I was considering this device instead of the both the Sigelei 100W and P4Y 150W. With those, at least I know they meet their published specs, again however weak they are. But the specs on this look like just straight out lies.
