This is a replacement atomizer for RN4081 e-Cigarettes. If you own one of these classic e-Cigarettes then you know how well they work even today! I still smoke mine from time to time!

These atomizers will also work on DSE103 batteries but DSE103 cartridges will NOT fit it. This is also a direct replacement for the SmokingEverywhere Gold e-Cigarettes and NJoy NPRO. Exact same manufacturer and quality as the Njoy NPRO replacement parts as well as SmokingEverywhere replacement parts.

We do carry blank refillable cartridges for these RN4081 atomizers as well as replacements for the Njoy NPRO and SmokingEverywhere Gold automatic e-Cigarette batteries. Exact same e-Cigarette factory but at a better price! You can refill any RN4081, NJoy NPRO or SmokingEverywhere cartridge with our quality Dekang e-Liquids.

These RN4081 atomizers are considered throw away parts and do not last forever. It is a good idea to keep at least one spare atomizer on hand as a backup.

(Cartridge/mouthpiece shown in photo is not fillable and is only there to protect the atomizer during shipping. Be sure to replace this with a full cartridge before smoking your e-Cigarette to prevent damage to the atomizer! You can use this mouthpiece if you prefer to drip smoke your RN4081)

• Genuine First Union design
• 25mm long (approx 1") without cartridge
• Compatible with all RN4081 e-Cigarettes and cartridges including Njoy NPRO and SmokingEverywhere Gold
