"Topping off" a Cartomizer?

[JCB1]

I'm using a Boge 2.0 Cartomizer on an eGo battery; used the condom method to fill the cartomizer; I just assumed I would need to repeat that step as necessary yet I've seen many references to "topping off" a cartomizer; that's dripping a few drops directly into the cartomizer??? I'm confused; I thought that was the purpose of atomizers?

Thanks!

With the Boge cartos, the first filling is critical; you have to make sure that the carto is fully saturated as the filler is very tightly wrapped inside and bone dry and won't wick properly. Once that first fill is successful and the filler is wet, it's OK to top off. Take off the end piece and drip from the bottle.

Top off early and top off often.

Happy vaping!
