FIELD OF INVENTION

This invention is directed to a rechargeable battery system for powering tattoo machines. More particularly, this invention is directed to a compact, rechargeable battery system with a voltage controller and variable mounting configurations for use with tattoo machines.

BACKGROUND OF THE INVENTION

Tattoo machines are conventionally powered by a mains supply, which typically involves a long cord. Tattoo machines can also be found using a battery as the power supply wherein the battery is affixed (tied) to the artist's arm with a power cable extending to the machine. In many instances, the prior art's battery connection to the machine is insecure, prone to rotation during use, as well as possibly disconnecting. Additionally, the arm-attached battery can be cumbersome with the weight of the battery on the artist's arm being a source of irritation as well as effect the tattoo artist's dexterity and skill. This is especially so during a long tattooing session where the battery may become warm. Rechargeable batteries, with “speed” control, for tattoo machines do exist, but the execution of the machine often results in inaccurate power control, not suitable for brushless DC motors, and an awkward cumbersome battery “pendulum” weighting on the end of the machine making precise control of the opposite, tattooing, end more difficult.

What is desired in the art is a compact lightweight rechargeable battery for a tattoo machine, with multiple adjustable tattoo machine to battery interface possibilities, to accommodate the artist's weighting and balance preferences, as well as providing easy-to-view status(es) of the battery health and voltage provision and adjustment modes.

SUMMARY OF THE INVENTION

The invention is a compact battery and voltage supply controller for a tattoo machine. The invention includes a battery system that allows the battery to direct-connect to the tattoo machine, through various internally received magnetic connection adapters, as well as providing easy-to-view status and health of the battery and incremental 0.01 V voltage adjustment using a voltage boost circuit or voltage modulator/potentiometer circuit actuated via a rotary adjustment knob.
