510 5V/portable passthrough battery

[lxrubin]

I wanted to post this in the 510 thread, but I guess I'm limited to this section for now.

So I found a passthrough battery for a very reasonable price ($10 CAD).
510 Passthrough - $10.00 : NorthernVapor.com, Canada's choice for vapor & electronic cigarettes!
There are two choices, a portable and a 5V. What would be the difference between them? I wanted to email the supplier but their store is closed until the 15th, plus I was hoping to get a few unbiased opinions while I'm at it. Would the 5V be considerably larger? How would it vape compared to my 3.7V stock 510 battery? The 3.7V is suiting my needs just fine, should I bother with the 5V, or should I get it for the sake of trying it out? or will it be considerably larger? Does the 5V option only work plugged in, and not portable?

Thanks in advance for the responses.

The 5V will vape better with an appropriate resistance carto/atty. If you put a 2.0 carto on it it will brobabbly burn it. A 3ohm att/carto should work great on 5V. If you use dual coils, the 1.5 ohm ones work great at 5V (3x3ohm coils)

The portable, I suspect, has an in-line battery but it will only provide 3.4-3.7V.

The power cord can be detached from the passthrough on the portable version. The 5V has a "fixed" power supply cord that can't be removed.
