I realize this is an old thread, but it’s the first hit that came up in the Google search I just tried. So figured I’d bump it for others searching the same thing.
It used to be that charging dual 18650 mods via USB just did not work very well at all. It wasn’t just like you guys are recommending against it. It was like some dual 18650 mods had a charging port. But you’d plug a USB cable in and try to charge and one of the batteries would charge but the other wouldn’t, or they’d charge unevenly or something like that.
You guys are still recommending against it. But it doesn’t sound like the situation is as dire as it used to be where it just wouldn’t work. I had a triple 18650 Wisemec Releaux device at one point I tried it with. And I forget exactly what happened, but I tried it one time and I was like, yeah. Not trying that again...
Did companies start putting some feature on dual 18650 mods that let you charge them via USB better?
I know most vaping hobbyists are adamant that they prefer external batteries and will tell everyone that’s what they should get. But I’m someone who really prefers USB charging. I have several USB charging stations, around where I typically am and it makes it effortless to keep my phone, keychain flashlight, mod, backup battery, TV remotes, etc.. charged. I’m not somewhere where I can just go in the other room and grab a couple of 18650’s a lot of times.
So for someone who’s basically chosen USB charging as a “lifestyle choice”, should I just go ahead and get an internal battery that charges via USB? The problem with that option seems to be that there are not many of these devices on the market with very large batteries. The main ones I’ve found are the Kanger Pollex, the Smok V-Fin, and the Innokin MVP-4. And the MVP-4 isn’t even listed on the Innokin web site as one of their recent mods any more. For various reasons, none of the mods am I really excited about. So it would open a lot of options if I could get a dual 18650 device like the G-Priv 2.
