Unfortunatly it does sound like you got a knock off. There's hope though! Actually a lot of options. You can either buy some joye cones & attys.....buy some joye or ovale ego-c atty's & cone....or just buy some ego mega duel coil carto's (which work really well)

or just get some boge lr carto's. Either way you a least still have a usable battery & can possibly fidget with the cone & atty you recieved..if you want that route. Here's a good video of adjusting & cleaning the atty's. I always push the wick in the spike with a paperclip about a 1/4 to 1/2.

One downside could be the battery may not last as long & another could be a malfunction in the battery. Just sayin' it could happen with knock off's.
If it was me I'd just order some lr boge's for both of them. They're cheap enough to at least try one or a pack & see.
