Hi Natura
I can tell you why I am looking for the same thing...an adapter for my kr808d-1 battery to a 401 atty. Dipping...
.and nothing short of a high voltage mod,which I don't want and can't afford, lasts as long as a 380mah KR battery. And the cartomizers are great for traveling and all around vaping. But....they hold almost a full ml of liquid or more so they are totally impractical for DIY juice making. I want the 401 attys so I can test liquids without wasting the liquid or the carto.The 401 has an exposed atty so you can just "dip" it into a little dish of juice. I found one at Health Cabin in China. So far I have found nothing else. I thought the 901-510 that EA has would work until someone was kind enough to get me to understand that although the thread pattern was the same as a 510 the adapter would not work for a 401. But he did show me how to make one at this thread
here.
The first bolded statement you would thin is true- BUT not.
Now if your willing to forget what it looks like and talk function we can have ya in one for under 20 dollars LOL. Welcome to my world of learning to Mod. My first was a box mod 900mah. Now I also got that big hugh lovely battery 3.7V of 3000 Mahs and a One dollar 3 piece flashlight ..my other favorite store is going to have battery connectors with wires already solder soon so you could actually make one with zero soldering too...for very little money. roflmao but that's not what you wanna hear now is it?
Ah I have got DSE301 attys that I just screw onto my 510 to test. I dip too for testing and then do plain PG inbetween. And you can use 808 cartos JUST drip..you can take out all the filling carefully and just drip into the tube that remains. I've done that too and for the cost of a blank cartomizer 1.50?? Don't bother driving yourself crazy. 1.50 carto for testing purposes until you run into that not so common adapter. I'll keep my eye out for them for you too. Trust me you will hear about it when someone stocks it lol.
OK so I just read that page you refer to here and I think..I see where your going..reason why this EA adapter won't work is by
KarrMcDebt
"M401 atty has a female connector Joye 510 battery has a female connector"
so EA goes 901/808 bat to -510 male atty -your 401 atty is female
LOL ones that poke out with threads is called male and the one's with a hole well der da females LOL
Hope that helps a little?
