If you have a DSE901 read this...

[trog100]

just in case anybody missed it.. the cooler running DSE 901 type only come in (shiny) white.. all the coloured and matt white ones will be the RN 4075 type..

the bestecig ones even thow they have a different number (BE901) seem to be identical to the the white HG DSE ones.. the carts differ but the atomizers are DSE ones.. the (BE901) carts are a very tight fit in the latest RN type atomizers.. too tight..

i am selling black true dse901's so you may be wrong.

 

[Kimmiegrif]

I had a battery go haywire...heated up the atomizer to bright red.

Atomiser on the left is an RN4075, the one on the right is a DSE901. The DSE901 came from a seller in China. You can't see it very well but the wire bridge is much higher on the DSE901 - it pushes quite far into the cartridge wool.



The RN type burns hotter. So gives a better throat hit, IMHO. But I think the DSE does a better job of leaching the available liquid from the cartridge, so you don't need to top off quite so often.

From these pictures, and from what trog says about matt white ones, black and pink ones being RN4075's, it appears that all mine are RN4075's. I've never seen a shiny white one. They are all from Simon. can anyone confirm that the model he uses is in fact the hotter Rn4075 type ? I'm not worried that they are, I can see why they would be labelled as 901s as the term is used so much, just wondering. I wouldn't know where to get an actual 901. does anyone?

All mine are the RN4075 sold as a 901 in white and black color. This is determined by viewing your examples.

 

[user-unknown]

are the batteries and atomizers interchangable for both the the rn4075 and the dse901. I bought the a rn labeled as a 901 and then i bought a true 901 from the china ebay seller for spare parts. will all of the parts minus the carts be interchangable.

I think this is a bit of a snag which could put some users off the whole vaping thing. It appears that purely by accident, I now have some of each. The first which I bought were described as black DSE901's but seem to be RN4075's.

Just this week, more black DSE901's from a different seller arrived which it seems ARE actual 901's along with the cartridges for them. The exterior boxes are identical, but the 901 has a two-pin power line and adaptor supplied, whereas the 4075 came with an empty power line box and a UK plugged power line in a separate box. Manuals for both say they are DSE901.

I discovered today I had been using a RN4075 two-piece cart in the 901 and thought how well it was vaping! Then I tried using the one-piece 901 cart in a 4075 and couldn't understand why it didn't seem to be working too well. I started getting an unpleasant burnt taste which I've heard others describe but had never experienced till now, so got into some investigating.

As far as I can tell all parts seem to be interchangeable apart from the cartridges, and the carts in one 'direction' as it were. I couldn't really tell that the atomisers were different but the 901 carts are definitely shorter if you put them side by side.

The only problem seems to be the difference in length of the carts - the 901 carts work just fine in the 901, but NOT in the 4075; they're too short and don't reach far enough onto the atomiser. On the other hand, the 4075 carts work so well on the 901 atomiser precisely BECAUSE they are longer - the atomiser is pushing further into the cart wool.

I'm wondering if this is the reason behind some reports of the 'burning atomiser' taste - people with the 4075's have inadvertently bought 'real' 901 carts not knowing they weren't long enough. Probably then went on to burn out their atomisers. Even the sellers themselves may be unaware of this difference.

I expect everyone else here worked this out from the other posts here but I confess it was only having this happen today which brought it home to me, along with the realisation that now I need some way to mark the RN4075's so I don't use the genuine 901 carts with them by mistake! The other way round is no problem at all.

 

[trog100]

there isnt any real length differences with ones we have.. the secret is to keep the carts wet.. and make sure the wool is up near the top and not pushed down into the cart.. tweak it out a bit if u have to.. a cocktail stick is okay for doing this with..

the cart wool must touch the atomizer bridge.. and be wet-ish.. semi dry carts just dont work and cause the burning taste.. more so with the hotter running RN type atomizer..

u might have some different ones still.. he he..

Ok, i checked noth the bacl and the white minis i sell and they look like the picture on the right so i guess im selling the "Real" DSE901's.

The batterys fit each model but it seems like the batterys i got with the "real" DSE901's last a bit longer. THis may be because all the other batteries i have are atleast 3 weeks older.

I like the mouth piece on the dse901's better, it feels better between my lips.

 

[trog100]

way back in May it was the the original 901s that people sold.. before the RN name change.. the cigs were a semi shiny white with faint green lines down them..

we smoked these for a while.. got around three hours out of them when new with heavy usage..

then some new matt finish white ones appeared.. instantly we noticed a battery run time drop off from three hours to two hours.. and after a weeks heavy usage this was down to not much over an hour..

i made a comment about this on the forum.. it was discussed and then forgotten...

in retrospect we now know what had happened.. the RN type had arrived.. no one seemed to know only that the old green striped ones didnt get sold any more..

two possible reasons for the downgrade in battery life.. one the RN type atomzer runs hotter and draws more current.. two the batteries might not be as good a quality.. possibly a bit of both..

the 901 battery life did downgrade thow without a doubt..

Just a bit more info - got my ruler out this morning and the apparently genuine one-piece 901 carts are 31mm long. The two-piece carts which came with my first 901 (which seems to be an RN4075) are 33mm long. A small difference but it appears that in this particular case size DOES matter! The 4075 battery is also a mm or two longer than the 901.

I'm now hoping that Trog is wrong and there isn't yet another (ie third) subvariant... I'd resigned myself to asking cartridge suppliers to get their tape measures out and tell me exactly how long their carts are (and in how many pieces) and reassured myself that at least if they were good enough to reply I'd know their service probably WAS up to snuff. Now there could be yet ANOTHER variable - heaven help us!

As I wanted to start selling a few of these myself this is worrying me a bit. Not talking major distributorship here, just getting some more local folk into the vaping thing. These will be people I will have personal contact with, so I don't need this sort of doubt about what they're getting. I'm not planning to become competition for anyone like Pillbox or Smokester and probably not even going on to eBay - unless someone wants to start paying me double price for customised atts and batteries (using nail art materials)! ...anyone interested drop me a PM!!

Just when I thought I was coming towards the top of the learning curve and pretty much knew what I was doing with these things...

 

[trog100]

there are other differences..

the RN type atomizers are a slightly smaller diameter.. have a slightly smaller air hole in them..

so the DSE type one piece carts are too tighter a fit in the RN atomizer and the RN two piece carts too loose a fit in the DSE atomizer..

our advice is simple.. keep some old carts for when the new ones u have dont fit properly.. this is okay when reusing the carts and topping up.. which we also advise..

the other thing we have noticed is the latest generation of RN batteries use a very thin walled steel tubing.. the brass end pieces can be pulled out of the battery very easily.. a couple of jiggles and a tug and out they come..

the build quality on the original DSE type could be said to be better..

Hello trog, I believe that the sedansa nano I is an actual 901, that has the shiny white finish and the higher bridge in the atomizer and it also takes the slightly longer and fatter one piece carts, the batteries are marked SLB. My experience of these batteries from sedansa is not good, so even though they have replaced them I prefer to use my generic batteries with it. And I also think that the generic RN 901 atomizer is hotter.
I’d also like to add that if you like to drink you liquid, the 901 one piece carts make the perfect straw . LOL

 

[usehername]

Here are some rough dimensions. The cart dimension is from the lip that would stop insertion to the edge of the cart that would contact the atomiser. (This is not the over all length of the cart which really is not a factor when you think about contact insertion).The atomiser dimension is from the top of the bridge to the edge of the tubing. Subracting the two would give an idea of how the cartridge filler makes contact with the atomiser.
DSE(slit one piece cart):9.5mm (Pointy atomiser):7.5mm
RN (round two piece cart) 11mm (fat atomiser): 9.5mm

Both designs provide relatively the same result. You can better understand what happens when you mix on with the other.
BTW totally by accident I am using a DSE cart on an RN atomiser which theoretically would be the worst match (near zero contact). In all honesty it performs perfectly. It actually leaches more of the liquid out before needing to top up. Might have something to do with little or no pressure on the top fibers of the filler against the atomiser. Just a theory..

 

[tribalmasters]

I bet even the RN types are made in different factory (could be wrong tho) I notice 2 types of matte 901 atomiser. Theres ones with a bridge that sticks out higher and it is slightly thinner, these atomisers also I have seen in pink, not too sure about black. They have harder draw but a much greater thoat hit, I have gotten these from Simon at Electronic Cigarette | Free Yourself... | e-cigs Welcome but not guaranteed, seems to be a mixed bag. The other has a flatter wider bridge, it has easier draw but is a far less satisfying vape with less throat hit. I get these from time to time also from Simon and Pillbox The Electronic Cigarette Company (UK) Ltd. the ones I got from Pillbox are marked with fancy gold Minicig lettering, the ones from Simon have nothing written on them. Check out the photo! The super hitting is on the left and has the thinner bridge. Sorry if someone found this out before, if so maybe at least the photograph is of use hehe!

--EDIT-- forgot to add that the same cart fits equally well in both of these atomisers!

 

[trog100]

the only real problem we have with mixing them is the too loose or tight factor..

we also like the hot running RN type but then again say it has to be kept wet.. it needs topping up often for best results..

the cooler ones (DSE) probably work best if no topping up is done.. just carts used.. they are very easy to flood and put the fire out so to speak.. the hot RN ones are impossible to flood and like being wet..

swings and roundabouts.. take your pick..

What do you think of the difference between my 2 atomisers in the picture? They both are matte and both not very old at all!

I bought a RN model awhile ago and now sell the true DSE901's. I think thst the 901's battery lasts longer than the KN's. I also seem to get more vapor with the 901 than the KN. I think the atomizer in the 901 uses power more efficient than the KN. The 901 are actually a bit shorter than the KN's Here are the measurments on my DSE901's. taken with a caliper.

DSE901
battery --- length= 66mm / width= 9mm
atomizer --- length=33mm / width= 9mm
cartrige ----length= 31mm
Over all length 118mm

KN model
battery --- length= 68mm / width= 9mm
atomizer --- length=33mm / width= 9mm
cartrige ----length= 33mm
Over all length 120mm

I think that the real 901's out perform the KN's. If you disagree please tell me why.
