POSEIDON Tattoo Battery Pack Rechargeable 2300mAh Cordless Power Supply — Black, LED Display & Adjustable 4.0–12.0V for Pen & Rota

The POSEIDON Tattoo Battery Pack is a lightweight, rechargeable 2300mAh cordless power supply with an LED display and RCA output designed to run tattoo pens and rotary machines for hours without cables.

This compact battery pack gives tattoo artists a portable, stable power source that replaces a tethered power supply. Built with a 2300mAh lithium cell, a precision-adjustable voltage range (4.0–12.0V in 0.1V steps), and a clear LED that shows voltage, runtime, and remaining charge, it’s aimed at artists who need mobility, consistent performance, and simple monitoring during sessions. The unit weighs about 66g, connects via a universal RCA output, and includes a built-in minute timer so you can track session length easily.

How long will one full charge last during typical tattooing sessions?

On a full charge the 2300mAh battery typically provides 6–8 hours of continuous use depending on needle configuration and voltage settings. Lower voltages and lighter needle loads extend runtime, while high voltage or heavy machine draws will reduce it.

• 2300mAh capacity estimated 6–8 hours under average load
• Adjustable 4.0–12.0V lets you balance power versus battery life
• LED shows remaining battery so you can plan recharge times

Will this power supply fit my rotary or pen tattoo machine?

Yes — the POSEIDON unit uses a universal RCA connector that is compatible with most tattoo pens and rotary machines on the market. It provides a stable output with precision voltage steps so you can dial in the feel you prefer.

• Universal RCA output for broad compatibility
• Voltage adjustable in 0.1V increments for fine tuning
• Stable output across settings to reduce needle speed variation

How does the LED display and timer help during sessions?

The integrated LED screen displays current working voltage, elapsed runtime (minute-accurate), and remaining battery, giving you real-time feedback. The timer helps with accurate session tracking for consistent workflows and transparent billing without needing a separate stopwatch.

• LED shows active voltage and remaining battery at a glance
• Minute-accurate timer records session length; restart to reset
• Simple controls let you make on-the-fly adjustments quickly

Is the unit rugged and convenient for mobile work?

Designed for portability, the POSEIDON battery pack weighs approximately 66g and fits easily in a pocket, kit, or clipped to a belt. Its durable build and neat packaging make it suitable for guest spots, conventions, or on-location appointments where a cable-free setup matters.

• Compact 66g body reduces hand fatigue and keeps your setup light
• Secure packaging and included power cable and manual for immediate use
• Rechargeable lithium cell for repeated use between gigs
