So I've been on vacation for the last week, which means quite a bit of time spent in front of the computer. As such, I've been taking advantage of the V4L pass-thru, with pretty good results - apart from it's thirst for juice 
So anyway, to make a long story short - If you're plugging your PT into a USB extension cable, stop it! Right nao!!! If it's possible by any means, plug that bad boy directly into the USB port and SMILE!
But seriously, wow, what a difference. I went from a somewhat noticeable improvement over the regular batteries, to a very noticeable jump in vapor and throat hit (even with lower mg carts). I guess even with a 4-5 ft extension, the power drain thru the wire was enough to nerf it's full potential.
This somewhat belated discovery came in the midst of some serious reading about a few of the HV mods out there right now. And now that I have the PT hooked up right, and seeing what V4L cartos can do at a true 5 volts, I'm super curious.
I hope it's not considered cheating, but I'd love to have this type of PT performance in a more portable format. I've already decided that cartos are way too convenient, and the V4L selection and service is beyond compare, so I'll definitely be sticking with them for consumables.
Let me be clear - I'm not disappointed with my V4L purchases in any way, shape, or form. It's a great product, and I'll be a V4L customer for life. But as part of the journey in finding exactly what it's gonna take to keep me off analogs (2 weeks now!), I feel compelled to research whatever it might be that will help along the way.
So is there anyone out there that has made the jump to an HV mod for use with the V4L cartos? For reference, the main candidate I've considered is the Prodigy V2.
Thanks all,
