Okay, so, let me tell you about this thing I messed around with the other day – this “Tombstone Double Cartridge Battery.” Sounds kinda morbid, right? But it’s actually pretty neat.
I heard about this doodad that lets you vape two cartridges at the same time. Yeah, you heard that right, two at once! Apparently, most cartridges use this thing called a 510-thread, and this battery is compatible with that. So, I thought, why not give it a whirl? I got myself one of these Tombstone batteries from Hamilton Devices.

First thing I did was grab a couple of my favorite carts and screwed them into the slots on the Tombstone. It was easy peasy. This thing has a 650mAh battery, which is supposed to last a while. I’ve heard that vape pen batteries can last anywhere from 4 months to over a year, so I’m hoping this one’s a keeper.
Once I had the carts in, I gave it a try. And let me tell you, it was pretty wild. Being able to mix two different flavors at the same time is a whole new experience. I tried a couple of different combinations, and it was like a flavor explosion in my mouth. One time I had a fruity flavor going on one side and a minty one on the other. It was wild, I tell you!
My Cleaning Routine
- Now, I also learned that it’s important to keep these things clean, so I’ve been using a Q-Tip and some rubbing alcohol to wipe down the connections every now and then.
- They say you should do it once or twice per cartridge change, but I just do it whenever I remember or when it starts to feel a little gunked up.
The Tombstone also comes with these two wax atomizers. I haven’t tried those yet, but it’s cool that they’re included. It seems like a whole other adventure is waiting for me when I get around to playing with wax. I’ve heard that the battery has an LED light that tells you when it’s charged. Green means go, or it just turns off when it’s full. Simple enough, right?
So yeah, that’s my little adventure with the Tombstone Double Cartridge Battery. It’s definitely a fun little gadget, especially if you like to experiment with different flavors. It’s like having a mini vape party in your pocket. Just remember to keep it clean, and you’re good to go!
