Premium 808 blanks vs regular?

[mle]

I feel kind of silly, but I'm hoping someone might be able to help out. I ordered some Premium blank cartos from Litecig and some regular blanks (both for the kr808d-1) to try them both out and see if I liked one or the other better. (Side note: first order with Litecig, very satisfied with the experience) The only problem is that I can't tell them apart

The only difference, from what I can tell, is that one kind has a smaller hole in the battery end than the other. Does anyone know which is which?

Thanks in advance for any help!

Duuurrr - realized the litecig Premiums are soft cap and the regulars are hard cap. Oops!

Also: These Premium cartos are AWESOME! No problems with the regulars, but I think the Premiums are what I'm sticking to from now on.

The Premiums and regulars may also have a different resistance rating.

Shawn,

Adding the ohm rating on the site would be helpful.

(I do see it is listed on the 'low resistance' cartos at ~ 2.0 ohms.)

Also, the standard blank 808D-1 carto page no longer explicitly states
that these are hard caps...

KR808d-1 Blank Cartomizers

Are these now the soft caps?

If so, are they a different ohm rating from the premiums?

KR808d-1 PREMIUM Blank Cartomizers

Would love to grab the Black Friday discount. But need to
know the ohm ratings. I already have some 'cool' karts at
3.4 ohms for my PT. But want to try some at mid range
to go with the new manual XL I also want to order. :~)

Thanks in advance!

It is 11:06 pm CST on Black Friday and the coupon code has expired.

The site says... "The coupon expired on Fri Nov 26 00:00:00 PST 2010"

By my calculation, it expired at least 3 hours prior to that time. :~(

I may still place the order and just order both the standard cartos
and the premiums to see the difference first hand. But with time
still remaining, I may find another Black Friday sale going on. :~)

Shawn said he would work on listing Ohm ratings.
The premiums are allegedly the same as Coolcarts and Turbos from other suppliers. Outstanding product. They run cooler and supposedly produce more vapor. They are 3.5ish Ohms.
If you like the coolcarts at 5V, I'd suggest the LR premiums at 3.7V. These combos both run 7-8 watts.

 

[dragginfly]

Thanks cappadoc.

I found in another thread users were reporting the LiteCig premiums
as 3.0 ohms, which should be about right for me a 3.7v.

Running some cheaper cartos between 2.2 ~2.5 ohms and they are
hot on the 3.7 batt.

2.0 LR may be way too low. I'm sure it also depends on the design of the
carto, too. A long thin coiled wire can have the same resistance as a
shorter straight wire, but have totally different heat transfer and temps.

Boge v Kranger is a good example.

There's just got to be a better way than buying a 5 pack of every design
from every supplier in order to compare them properly.

 

[dragginfly]

Went ahead and placed the order, including KR808D-1 Premium Blank Cartomizers ... AND... KR808D-1 (regular) Blank Cartomizers so I can find out first hand.

I'll post back my experience and comparative review complete with ohm ratings.

Too bad I missed that Black Friday special. With the 10% off I could have saved a hundred bucks!

OK... not really. lol

The good prices and low shipping makes up for it. :~)

This post will answer the OP question and illustrate observed differences
(in addition to the hard cap/soft cap difference) between the LiteCig Regular
and Premium cartos for the KR808D-1.

I am relatively new to the ECF and vaping in general. So this is not to be
an exhaustive review of performance or vaping quality. But I did promise
to share my findings about resistance in these cartos.

My order of cartos arrived today from LiteCig (Thanks Shawn!)

I ordered one 5 pack of each, Premium and 'Regular' KR808d-1 cartomizers.
(Plus a new XL manual battery and a bottle of RY4 for good measure.)

KR808d-1 PREMIUM Blank Cartomizers

The Premiums are individually wrapped and packaged in a box almost
identical to an order received from "The Other Guy" (TOG), which are
reported to be manufactured by Boge.

TOG calls his "mega" cartos, which are rated at 3.4 ohms. I've been
using them on a 5v PT. But wanted to find some just like them with
a lower ohm rating to use with the 3.7v battery.

The LiteCig Premiums are labeled with 302D 3ohm on the box top.

(Sorry that pic is a little out of focus.)

I metered three of the five cartos. Two measured 3.2 ohms, while one
measured just 2.2 ohms. I labeled the 2.2 and set it aside for another day.

The carto caps are the soft type and easily removed. Looking down
inside the carto from the open cap end reveals this is the premium
design I was hoping for.

A slightly heavy atomizer wire running straight rather than coiled,
along with fiber material that practically sucks juice into it.

On my 5v PT it's performance is almost identical to TOG cartos I've
been using.

On the new manual XL the vapor is a bit cooler than I was looking
for, but definitely acceptable.

KR808d-1 Blank Cartomizers

The 'regular' cartos appear to be from a different manufacturer. Most
likely these are Kangers based on descriptions I've read in ECF.

These are also boxed. I did not realize these were the common blister
packs I've seen around until opening the box.

These do have the hard caps. But the caps can be removed and
replaced with a spare soft cap (not included).

The 'regular' cartos are also slightly shorter in length than the Premiums,
but still hold just as much fluid (approximately 1.2 ml on first filling.)

These also have the longer plug built into the condom for the battery end.

I removed two from the blister pack to test for resistance. Both
measured 2.8 ohms.

Design of the atomizing wire itself is the biggest difference
between the Premiums (Boge) and Regular (Kanger). These
regular cartos appear to have a coiled atomizer which is not
visible at all from the open end of the carto.

Primary differences between the Premiums and regular are:

3.2 ohm v. 2.8 ohm
straight wire v. coiled
soft v. hard caps
Boge v. Kanger (assumption based on ECF reports)


Personal opinion:

I'm glad I decided to purchase BOTH types so I could try them myself
and see the difference. The differences in resistance give me
more options for using at different voltages or juice mixes.

The new 'regular' cartos from LiteCig are a much higher quality
than regular coiled wire cartos I've been using with my batts. The
higher resistance in these will help the batteries last longer while
keeping the vapor cooler.

The filler material is also better and is the same as that in the Premium.

While many in the ECF call the Kangers "cheap" quality, these
are definitely better than what I have been using on my batts.

I do like the Premium (Boge) straight wire design better than
the coils. My experience with coiled wire is that they tend to
clog up with juice rather easily.

A lower resistance in the Premiums would be preferred. At 3.2 ohms
there is no noticeable difference from TOG... except that LiteCig
has better prices. :~)

My plan is to use the new 'regular' cartos on the batteries and
keep the Premiums on the 5v PT.

I will, however, keep looking for a Boge carto with a ~2.8 ohm rating
to eventually replace the coiled wire Kangers on my batteries.

(in addition to the hard cap/soft cap difference) between the LiteCig Regular
and Premium cartos for the KR808D-1.

Thanks for such a helpful and informative post

Thanks dragginfly - I had figured out how to tell them apart, but the info about the resistance and the wires is very helpful. The Premiums are awesome; I really like how they work with my 902(808). I had considered TOG's cartos, but based on your findings it looks like LiteCig is the way to go.

 

[dragginfly]

A quick update.

Ignoring manufacturer, resistance, and cap (hard/soft), the
only real difference is the design of the atomizing wire.

The Premiums have the straight heavy wire, while the regulars
have the thin coiled wire.

From a power standpoint, a 2.8 ohm carto will generate more
power than a 3.2 ohm carto at a given voltage (assuming
adequate current to meet the demand).

If more power = more vapor, the 2.8 ohm coiled wire should
produce more vapor than the 3.2 ohm straight wire.

However, this is not the case.

More power does not necessarily mean more vapor production.

I believe vapor is a matter of heat transfer from the atomizer
to the e-liquid. Power is a factor, but not the only factor in
heat transfer.

This is a topic I have speculated on in another post. But this
direct comparison confirmed my suspicion.

After a day of use to break in the new cartos, I compared the
3.2 Premium (straight wire) to the 2.8 regular (coiled wire) on
both the new 3.7v XL battery and the 5v PT.

In both cases, the Premium produces more vapor even though
it has a higher resistance.

The answer is in the heat transfer.

The lower resistance builds more power. All power is converted
to heat. But not all heat is transfered to the e-liquid!!

The Premiums do a much better job of transferring heat to the
juice, which absorbs the heat through expansion and carries it
out of the carto.

Next test...

I stated above that prior to this order I was using coiled wire
cartos rated at 2.2 ~ 2.5 ohms on my 3.7v 808 batteries.

They do OK when new. But they tend to clog and burn both
juice and the cheap filler material.

cappadoc (above) suggested I try the Premium LR (2.0 ohms)
but I declined because they would likely be even hotter than
the ones I already have problems with.

one measured just 2.2 ohms. I labeled the 2.2 and set it aside for another day.

Today was the day.

I put the Premium with the 2.2 ohm resistance on my 3.7v
battery... and it produces a great deal of warm vapor. Much
more than the cheap coiled wire cartos I've been using. The
air flow is much better, which should keep the juice from
over heating... plus the better filler material should not tend
to burn as in the cheap cartos.

(I thought this would be a quick update. I do type fast, though. lol)

In summary, I plan to get some of those Premium LRs to add
to the collection!

I still would prefer the Boge with a resistance around 2.6 ~ 2.8
to test. I think my sweet spot will be in that range.

This also does not mean the Kangers are 'bad' at all. They
just don't produce as much vapor and I expect the coiled
wire and poorer heat transfer will lead to more clogging.

Some may prefer the 'regulars' with less vapor.

For me, I'm sold on these Premiums big time!
