It would depend on whether or not there was a qualitative difference between the two. I wouldn't just spend more money for the sake of spending it...? Im asking is there a reason other than its more expensive so it must be better
Yeah right, I'm sure you wouldn't.
Personally, there are some things I just don't go "cheap" with when making purchasing decisions. One of them would be brakes for my car, and I don't mind paying industry standard prices for brand name brakes. My life and the life of others could depend upon the quality, performace, and safety of the brakes that I choose for my car, so I choose not to skimp in this area and not look for "sales" for dirt cheap, no name brand brakes whose build, materials, and overall quality might not be up to snuff. I guess I call it the "peace of mind" factor.
The same can be true for Li-ion batteries and of the chargers for them that we use for our electronic cigarettes. I personally place the importance of a good charger and batteries right up there with my auto brakes. I figure that I use my PV more times throughout my day than any other device I own. Not only that, but I put that device right up to my mouth/face each time that I turn it on.
I'm not the most handsome guy in the world, but I kinda like the way that I look and would like to keep it that way. I don't need some cheap no-name battery to explode half my jaw away because at the time I purchased that battery it was a steal at $6.50 off of E-bay, when the typical going price for a genuine, name-brand AW battery from a reputable dealer would have cost me a whopping $8.
Is the genuine AW brand battery actually a safer battery than a no-brand battery? Honestly, I don't know, but I'm going with the AW. It's the "peace of mind" factor. I place more priority on safety of a known reputable product over financial savings of an unknown product. If you remember, I'm the guy who had a less reputable brand battery vent in a PV, so I'm a little more sensitive to this issue than many other vapors.
The same holds true with the Li-ion chargers available to us. For years the Pila has been the top dog in the flashlight and e-cigarette industries for recognized quality, features, and expense. Sort of the Provari of the Li-ion battery rechargers. If you wanted one you were going to be paying two or three times more for one than a no-name brand or a Trustfire charger. Is the Pila worth the extra money? Only you can answer that. I chose to buy both a Pila and a Provari, I'm a brand name kinda a person and don't regret my decisions one bit. I have peace of mind and I don't mind paying more for that.
There are X-tar and NiteCore brand chargers available now that look to be competitive with the quality, features, and price points of the Pila. I likely would feel comfortable purchasing either of those three if in the market. However, because of that "peace of mind" issue I have with batteries and chargers, I would never purchase a battery or charger that was not made by the three main manufacturers of Li-ion batteries or chargers.
You may be the type of buyer who feels better about themselves about saving a $1 here or there and is not into brand names or the reputations of brand name products. And that's fine, as that is where your "peace of mind" priorities are which may be different than my own.
