I love my 4081 on a box. That batts just take such a pull! I gave up. Keep them charged for emergencies. Good unit, we just paid too much.
So, if DSE 103 batteries are compatible with the RN4081 parts (minus cartridge) it would follow that a PCC for the DSE 103 would work for the RN4081 batteries, right?
I've also heard 3rd or fourth hand that the 510 pcc works with the 4081. It makes sense at least - the batteries are the same gender and diameter, voltage and amperage. The connector has a different thread pitch, but it doesn't look like that matters. We'll soon see, I've just made my first order from ruyandirect, including a 510pcc, but after trying to fall in love with my 510 all week to justify the expense, it's the 4081 that I keep going back to.
I need a 4081/103 passthru now - I picked up a usb battery pack tonight, and with a set of 4 1600mah or better AA batteries in it, that should make a heck of a PV.
I have a very hard time using mine because of the mouthpiece cart shape. For me it is a work out to get a puff off of it. If there was a whistle cart that would work on it then it would be a really good unit for me.
If the connector has a different thread pitch, I don't think it will work.
Atomizer care is a crap shoot. No one really knows a good procedure. Some people clean them out every night and let them drain. Some wash and blow them out on a regular schedule. As for me, I do absolutely nothing to mine. My latest one is going on 3 months and running like a champ, but others who are cleaning regularly them claim 2+ months also. The choice is yours.
Some folks are complaining that their attys only last weeks or days. I honestly think it's the type juice being used, but I can't prove anything.
