KR808D-1 vs. 510 Which OHM. Carts

[gsx678]

Ok,
Here is my thought.
I have been using the KR808D-1 for sometime now and love it.
I use a manual USB passthrough for the same and it is awesome.

I am getting ready to buy some new stuff.
Should I even consider the 510 or stick with the KR808D-1

I new new carts and am curious about the XL and Clearomizers but not sure whats good.

Also in regards to the Ohm rating of carts. What is better for a passthrough that is supposed to be 5 volts and what is better for a 3.7 battery.

Any help and input would be great.

Thanks in advance.

I'm in the opposite boat, thinking of switching from 510 to 808. I would love to hear everyones thoughts on this as well.


In regards to my 510 experiences, they freaking work with like, everything. Honestly I'm just bored with 510. My clearomizers all cracked on second/third uses. Cartos are hit or miss, tanks mute flavor and I've always hated cart/atty combos. I do drip and also have a bottom feeder, but for an out and about simple setup I want to try what 808has to offer.

Not much difference imo, just the connection type and 510 has more compatibility but that's a non issue with an adapter. If your talking about switching from a normal 808 battery to a normal 510 battery I don't see much use in it. The 808 will have bettter battery life and slightly strong ouput closer to 3.7 where the 510 is more like 3.4. If you want to upgrade battery types and go for an Ego or Riva which will give you longer run times in between charges it might be worth it.

For ohms at 5v I prefer 3 - 3.5ohm, somewhere in that area. For 3.7, anywhere in the mid 2s and under. but don't go below 2 with the proprietary batteries.

Typical "sweet spot" is around 8 watts, 3 - 3.4 ohms on a true passthrough. With a good 2a usb power supply you can go as low as 2.5 ohms, but I find it tends to be unpleasant.

Kr808 std carto is 3 ohms, 2.6 ohm for lr. V4l coolcarts are up in the 3.3 - 3.4 zone.

Std 510 is around 2.5 ohms. With a riva or other fat batt 510 i like 2 ohms. Lower resistance, like the newer 1.5 ohm dual coils are to me at least questionable with standard riva or ego type batteries - over 2 amp draw might be a bit too much for the batts or electronics st lfest long term.

 

[gsx678]

so what are the differences between ohm numbers as far as vapor production and taste?

 

[CraigHB]

It mainly comes down to heat or power (equal to voltage squared over resistance). Lower resistance consumes more power and makes more heat. Higher voltage does the same thing. That results in warmer vapors and higher vapor production. You can go too hot for your personal preference though. You also drain your batteries faster and use more juice with lower resistance. The same is true for higher voltage, for example, when using a battery powered VV (variable voltage) device.

More heat also has an effect on flavor, but different flavors react differently to more heat. Some are more rich, others can taste burnt.

With 5V you would typically use a 3Ω attty/carto. For 3.7V, you would typically use a 2Ω atty/carto. 5V and 2Ω would be hot. 3.7V and 3Ω would be cool. That's not a bad thing though, it just depends on personal preference. You have to play with it a bit to find your own sweet spot. For me, 5V and 3Ω just about nails it.

It's all about voltage, mAH, size, and available cartos and atties and the differences are shrinking by the day. Is there something you want to try that's not available with your current batteries?

 

[gsx678]

not that i want to try something new. just not sure how it all works.
all your input is very helpful.
i do think the 5 volt passthrough is awesome and was wondering what carts to use with my regular battery.i have just regular ones now and they are ok. just trying new things.

 

[AttyPops]

FYI - when you say carts, I think you mean either atomizers (atty) or cartos. Carts are the plastic tips for the atomizers (they have no coil or electrical stuffis).

As noted above... it's about the heat. So assuming whatever you use for power supplies enough amps, you can use V*V/R to get watts.

Example: 5 volt PT... 5v * 5v / 3.0 Ω = 25/3 = 8.3333 watts. Plenty hot enough IMO. More than that and it starts to get too hot IMO.
Similarly, 2.0 ohm on a 3.7 v battery is 3.7 x 3.7 / 2.0 = 6.845 watts. Good. OTOH 1.5 ohm is 3.7 x 3.7 / 1.5 = 9.13 watts... too hot IMO.

Now you have the formula... as long as you know the battery voltage and atty ohms.. you can tell.

 

[CraigHB]

Yea, but "too hot" is also a relative term. There are people on the forum here that claim they like a 1.6Ω dual coil carto at 6V, that's a whopping 22.5 Watts. I don't see how that's possible, but people have said it. That's like vaping off a volcano (like the kind that spew lava). They must have cast iron mouths.

Oh, one other comment about calculating power. 3.7V is a good number for the unregulated single cell devices, but devices like the eGo use PWM (pulsed output) to regulate to a somewhat lower equivalent voltage. I've found 3.5V a good number for the eGo. In that case, an eGo with a 1.5Ω atomizer would be putting out almost the same heat as a 5V device with a 3Ω atomizer. Though 1.5Ω is a little hard on the eGo electronics. The LR atomizers Joye (the maker of the eGo) supplies are 1.7-1.8Ω

If you want to try the ce2, I suggest 3.0 to 3.2 range for your 5v PT. You always have a little bit of lee way with a button. If vape is little cool, preheat a little, too hot, get off the button before finishing your draw.

I like the ce2 but I'm willing to put up with them for the clean taste. But they are fiddly. Watch some videos and see if you think you can use them or not.

 

[AttyPops]

Yeah, he asked specifically about 5 volt and 3.7 volt and is using KR808D-1's. The eGo note is good for general reference tho.

 

[gsx678]

I am referring to cartomizers.
I am just trying to figure the best ones to use with my 3.7 batterys and the best ones to use with the 5 volt passthrough.
JD1 got the closest....lol
seriously though...all this info is awesome guys......thanks tons....keep it coming...maybe one day i will figure it out..lol

Cartomizers -- the best (most popular) KR8 cartomizers seem to be Bloog MaxxFusion, SmokTech dual coil (use only with a big battery), Echo, and Boge LR. The SmokTech dual coils give you strong flavor and a hard throat hit and they seem to last forever. The Bloog MaxxFusion type gives you a more mellow and velvety experience (the vapor and throat hit is smoother and more lush). I have not tried the Echo but I believe they are similar to the Bloog (but hold much more juice). The LR cartos would be more similar to the SmokTechs but I think the SmokTechs are better.

I believe one advantage of the KR8 system is they have very good auto batteries. The 510 has more options for attys and tanks.

 

[AttyPops]

The wattage calculation is the same for atties and cartos. Carto is just an atty with filler/tank around it for this purpose.

5 volt PT = 3 ish ohm carto.

If you want to use dual coils (2 x 3.2 ohm coils) fine, but you need to draw 3.125 amps at 5 v.
