Concealed 510 Batteries

A discreet 510 battery holds the cartridge inside its housing instead of leaving it screwed on top. The cart connects internally and the shell closes over it, so the device looks like a plain slim body rather than an obvious vape pen.

On a standard battery the cartridge sits above the body and stays visible. On a discreet battery the cart goes inside. Same 510 connection underneath, same cartridges, but nothing protrudes and nothing identifies what it is at a glance.

Yes. Every pen here uses the standard 510 thread, so the cartridges you already buy will connect. The only limit is physical size, because the cart has to fit inside the housing for the device to close properly.

Most will, but not all. The housing sets a maximum length and diameter. Very tall or unusually wide carts can be too large to enclose. The adjustable models take the widest range, and the two gram friendly bodies are built for larger carts.

Yes, all of them. They charge over USB and most carry an LED that shows the level. Use the cable that came in the box, and avoid high output chargers or car ports, which push more current than these are designed to take.

The UNI X and the Micro Max have the shortest bodies in this lineup, both at twenty nine ninety nine. If the shortest possible profile matters more than a wide fit range or extra voltage settings, start with one of those two.

On most of them. The adjustable pens step through voltage settings so you can match a cart that runs hot or thick oil that needs more power. The draw activated Flow has no button and no settings, which is the trade for simplicity.

The Recon Pro Dual and the Recon 4g Dual do. Both hold two carts inside the same body, so you can carry two without carrying two devices. They run thirty four ninety nine and sit at the larger end of this lineup.

Open or slide back the housing, seat the cart on the connector inside, then close the shell. Do not over tighten. Finger tight is enough, and forcing it is the quickest way to damage the threading on either part.

Usually a loose connection or a flat charge. Take the cart out, check the contact is clean, reseat it finger tight and charge fully. If a draw activated pen still does nothing, residue on the sensor is the next thing to look at.
