ive been using a kanger subox for about 2 months now and the last few weeks it seems as if it's not getting any higher than 20w. All my batteries are good they hit hard in my mech mods.before I noticed the power drop I kept it around 35w with a .4 coil in the rebuildable section of the subtank. But now I crank it all the way up to 50w and it's barely even warm with minimal throat hit. I put my derringer and mutation rdas on it and they fire like the battery is dead. Anyone have a solution or the same issue.
Kanger subox has lost its power

I also should add it constantly does a reboot of sorts. If I haven't hit it for a while I fire it to check the battery, shows full and I give it a puff...nothing. I check the screen and it's says kanger tech as if I just popped in the battery. Sometimes it'll do it 4 to 5 times back to back. Not much good about my subox 
I absolutely loved it until it lost all its oomph

Without a reading from an inline voltmeter it could potentially be the boost circuit in the PCB has finally given up the ghost being pushed hard so long.
i haven't really pushed it to hard like I said my average was about 30w while on breaks at work I would push it to 35 and my days off I keep it at about 25 to save battery
yeah, with your second post about it continually rebooting, I'm wondering if a circuit on the PCB or even a grounding wire for the PCB may be loose or come disconnected. Everything being described is in the internals of the mod itself. Even a wrongly done solder point under stress could come away and such when at 50% max setting, the solder point not being right could get hot enough to come loose as not the optimal amount of contact was welded there to begin with. Diagnosing mods over a computer screen is like diagnosing a dodgy computer over a computer screen, most times best to see in action what is going on really and I am just pulling off my knowledge of general electronics atm.
I'll probably take it apart tomorrow and check it out. I've got some solder laying around somewhere. I may just redo all the wiring in there
I'd give the PCB a good thorough look over under a magnifying glass and direct light, check for any discolored or peeling layering as well as maybe bad diodes and such before checking the circuits with a multimeter as well.
