Cloak Battery - Hamilton Devices

One of Hamilton Devices' original concealed 510 batteries, the Hamilton Devices Cloak earned cult status as the first mass-market device to prove that hiding a cartridge inside a compact, buttonless body could be both practical and premium. Inhale-activated and entirely button-free, the Cloak fires the moment the user draws—a simplicity that set the template every concealment battery since has followed. The internal circuitry is engineered specifically for CCELL cartridges, delivering smoother output on CCELL hardware than generic 510 batteries that weren't designed with CCELL's resistance curves in mind. The power range is tuned for the sweet spot where most oil cartridges perform optimally, eliminating the need for user-adjustable voltage and the confusion it creates for non-technical customers. For retailers who stock the upgraded Cloak V2, the original Cloak serves as a lower-priced entry that captures budget-conscious customers while keeping them in the Hamilton ecosystem.
