I have tried both ways
For me it is a lot better to use the external charger.
It's not bad for mod or batteries to charge with the usb port.
I noticed that after I used the usb to charge for extended periods of time the batteries would say 100% but when I put the batteries in the external charger they weren't fully charged.
I had this happen with a couple of different brands of mods
But then again, I've heard of people using the charge port with no issues.
Some mods charge better than others.
I found a thread about external vs on board charging.
it's an older thread but still a good place to see how people feel about it.
Just bought a VOOPOO DRAG. Loving it so far. It might sound stupid but I hate external battery chargers. They're inconvenient. What are your thoughts on charging through the USB port? It seems like the device is very secure with 8 ways of security from power and short circuits. I always read...
