When charging a mod via USB, the mods charging circuitry decides on the max current flow, not the cable or the USB port that you plug it into (the USB port will have a max current limit depending on type). Not quite sure what you mean by "modern phone charger"
Any USB port that you plug your mod's charging cable into, simply provides 5v d.c. across pins 1 and 4.
Technical issues aside, and I'm no expert, my point was that if you don't have 100% confidence in the chip then you want the maximum current to be as low as possible.
I believe there are phone chargers that charge at 3a - it's fine to use one of these with a Yihi or Evolv mod, but I wouldn't trust a low end Smok mod to manage a 3a current.
