So what different dc power source can i use?, do you mean i may aswell not bother with vaporizers that need these chargers? thank you
I can't really advise you in what is best as an alternative since i could lead you in the wrong direction, but there are more elaborate power sources, variable dc power sources and overall bigger units that should have better reliability than these chinese dc power supplies we get for these units.
I must say, the power source is IMO the biggest "flaw" in log vaporizers. Several electrical stores told me that these 10$ power supplies will eventually fail, there is not point in getting too caught up about it.
So, that is why i said that the power source you buy, or the log vape you buy won't influence how many of these things you'll need until the vaporizer reaches the end of its life.
The choice is up to you... to me it's worth it. The one i have now has lasted me 6months already, the other two lasted 6months together... it is a bit unpredictable.
There was a thread about variable power supplies somewhere in FC, search for it, maybe you'll find your answer there.
