Unfortunately, the Pax Era battery doesn't work with standard screw-in cartridges.
The Pax Era is the best and smokes smoothly. However, the seller did not indicate in the listing that this vape pen (battery) does not work with standard screw-in cartridges. That information should be prominent, loud and clear.
Special cartridges are needed for the Pax Era and not only are they expensive, they only come in half gram cartridges. Those half gram cartridges are about the same price for full gram, standard screw-in cartridges.
Full disclosure and all pertinent information should be supplied in every listing for a product. The battery is wonderful but the cartridges for it are way too expensive.
