KR 808 s in a 5 volt box mod

[Roaddogg]

Probably a stupid ??? But will I fry my KR 808 carts screwed into a 901 threaded 5 volt box mod , and what's a good atty for a 5 volt box mod, I'm used to cartomizers, never done the separate atty deal before .

U can use the KR808 carts with 4.5 ohms, at home i use these ones for 5 volts and the ones with 5.3 ohms to 7 volts, or use attys 3 ohm´s plus for the 5 volts.

My understanding is that you can use 901 atty's on 808 stuff BUT NOT 808 atty's on 901 stuff (without an adapter) because 808's have airflow holes in the battery end and 901's don't -- so you won't get any draw.

Someone correct me if I'm wrong.

So I need a 901 to 808 adapter with airflow holes, hmmm , anybody know a quick place to order ,

so I guess I won't blow off my wifes hand, or we won't be inhaling burnt polyfill on the first puff putting a KR 808 on 5 volts

It depends. Something needs to let air get to the hole in the bottom of the carto. Real 901 attys and cartos have a hole in the middle of their side to let in air so they don't care as much about getting air in through their threaded end hole.

If the center post of your mod's threaded atty socket has a recessed groove cut all the way across the post (like PigCig which is 901 and the brand of Riva 901 at Liberty-Flights) then most KR808D-1 cartos will get airflow without an adapter. If the atty socket post is just a featureless flat circle or a flat circle with a hole in the middle, you might need to provide additional airflow for some cartomizers. The KR808D-1 cartomizers I use all have a bit of a groove cut across the center post of the carto so those cartos might not need an adapter (depends how well the groove is cut). But some so-called KR808D-1 cartos (like leCig D1 and the maybe the Vapornine ones) do not have a groove cut across the center post of the carto so they would be more likely to need an adapter.

BTW Vapor4Life Coolcart blanks, according to them, are 3.4 ohms and do have a groove cut across the post

The best atomizer/cartomizer for a 5 volt PV, IMO is the low bridge 801 or BE112 (Liberty Flights) which also comes in a mini version (Ikenvape). A good and very inexpensive 801 carto is the one MadVapes sells. Many vets use 801 type attys/cartos.

Also,it depends which cartos your using.The Bloogs and Volts dont do well at higher volts.I use the V4L coolcarts at 5v and it works great.

Thanks everyone

No big deal. Standard 808 carto is about 3 ohms, while higher resistance, like vapor4life coolcarts, might push to about 3.3 - 3.4 ohms.

That's actually "sweet spot" vaping, right around 8W power. (5x5/3).

You can also use nominal 808 low resistance, down around 2.5 - 2.6 ohms, but I've always found that kind of harsh, pushing at about 10W.

(A classic 808 pass-through, like many of us have used, and enjoyed, is a 4.8 - 5V 808.)

Roaddogg (guessing sir?) while v4l lists the cool carts at 3.4 ohms on their sight the average all my tests show is actually 3.3 (technically 3.284, but rounding up), they can be as low as 3.0, gotten a few as high as 3.7.

Thanks again , big help now at least I have some options to try, and see what works for me without wasting my hard earned bucks , trying to figure out stuff on my own. One of the reasons I tell mt lovely wife" I ain't no plumber" although she seems to think I am .
