There are two things that you can try to get it to work on your ego battery.
First is the toothpick trick.
You can use a toothpick or paper clip to try and pull out the center contact of the
atomizer. Only need to bring it out ever so slightly.
Put the toothpick into the center hole and try pull and wiggle the little tiny
contact out. If you use too much force, it could pull it out and damage the atomizer.
Very difficult to understand without seeing it. But once you see it and know how it works,
it can get alot of atomizers that were thought to be dead, come back working.
** I would say to check out GPTV, and then ask in the chat for the host to show how this works.
not everyone knows the trick, but some do.
Second, you can try to use an adapter, but it will change the looks and overall length of the unit.
Look under the PV adapters, and select the 510-510 extension.
This will allow a bit of play and overall adjustment for airflow.
