I personally like Efest chargers along with Nitecore since they both run off their own power supply.
Excellent point. Unless we test or find a review on said external power supply, how do we know the quality of it? Not to mention the wear and tear on a USB port from the constant use.
Low or high voltage delivery from the PSU could have adverse affects on the rest of the electronic circuitry.
I'm not just making quasi-veiled references to your personal character; I'm also still calling you out for the fact you got caught with the unscrupulous pretense of having been judging entire coil types merely by claiming advanced coil builds don't give more than 10 percent better flavor when the reality is that you haven't actually even tried to vape on a decent set of alien coils before, after which a legion of trolls immediately jumped in to desperately try to obscure that. If I ever threatened you with destruction, it's because you're so funny that you're indestructible.
