Equalizer Wireless Neutron 2 tattoo machine

Complete guide: Equalizer Wireless Neutron 2 tattoo machine

The Neutron 2 from the Equaliser range by Kwadron is a wireless pen-style tattoo machine, the successor to the Neutron model, designed for artists who want freedom of movement without cables and fine control over working parameters. With adjustable stroke between 2.6 and 4.0 mm, adjustable voltage 4–12 V, and a dedicated SMP/DOT mode, it covers both linework and shading as well as micropigmentation. The package includes two replaceable 2100 mAh batteries, so you can work long sessions without charging breaks.

How to use

1. Before the first session, fully charge both batteries with the USB-C cable and adapter from the package — a full charge takes about 1.5 hours.
2. Sanitize your workstation, put on gloves, and cover the machine with a disposable protective barrier (pen machine cover/film), leaving the display visible.
3. Attach the battery to the machine and mount a sterile, disposable needle cartridge suitable for the technique you are working on.
4. Adjust the stroke in the range of 2.6–4.0 mm according to technique and style, then set the voltage between 4 and 12 V; you can save 4 voltage presets for each power mode that you use frequently.
5. If you are left-handed, rotate the orientation of the color display for comfortable reading.
6. Turn on the machine (the Jump Start function makes starting simple), check the needle movement, and do a test on a practice surface before touching the skin.
7. During the session, monitor the parameters on the display and use the built-in session timer; when the battery runs low, switch it with the second charged battery and continue working.
8. At the end, dispose of the cartridge in the sharps container, remove the protective barrier, then wipe the machine with a surface disinfectant compatible with electronic equipment.

Tips from us

• Always keep the second battery charging during the session — with up to 5 hours of operation per battery and 1.5 hours of charging, you practically never run out of power.
• Save the 4 voltage presets for your usual techniques (e.g. lines, shading, filling) to quickly switch between them without manual adjustments at each change.
• For dot micropigmentation and scalp, use the dedicated SMP/DOT mode, which allows full adjustment of needle movement and frequency.
• Adjust the stroke according to style: generally, a shorter stroke is preferred for fine shading and delicate pigment, while a longer stroke is for lines and filling — test on synthetic skin until you find your settings.
• Use the session timer to track your work pace and breaks, especially on long projects.
• The 27.5 mm grip and 210 g weight make the machine comfortable for long sessions, but it's still worth taking regular hand breaks.
