Complete guide: CHEYENNE SOL NOVA UNLIMITED II 4.5MM
Professional wireless tattoo machine made in Germany, in the 4.5 mm stroke version — a configuration designed for shading, color packing and realism work with large color surfaces. The BLDC motor runs silently with reduced vibrations, and the integrated screen shows you real-time frequency, operating mode and battery level. It is a choice for professional artists who want over 5 hours of autonomy, quick battery change and the ability to switch between strokes via interchangeable drive units.
How to use
- Before the first session, fully charge both Keeppower 18500 Li-ion batteries (2000 mAh) in the included charging station; for fast charging (approx. 2 hours) use a QC3.0 5V source with at least 1.8A.
- With gloves and on a sanitized work surface, mount the compatible grip (any SOL Nova Grip or Disposable Grip One Inch / Ergo Round) and a sterile, sealed needle cartridge, checked before opening.
- Slide the charged battery into the machine's sliding unit and turn it on.
- Choose the operating mode that suits you: the 3 classic buttons, the classic SOL Nova Unlimited gesture, or the new volume gesture control.
- Set the frequency in the 25–150 Hz range depending on technique and choose between Steady mode (constant stroke) and one of the three Responsive modes.
- Continuously adjust the needle depth (0–4.0 mm) according to the technique and cartridge used, then apply disposable protective barriers over the machine before starting work on skin.
- Monitor the parameters on the screen during the session; if the battery runs low, change it in a few seconds via the sliding unit without losing settings.
- At the end, dispose of all disposable consumables (cartridge, barriers, disposable grip), decontaminate the machine surfaces according to the manufacturer's instructions and store it in the included transport case.
Tips from us
- Always keep the second battery charged in the station — swapping via the sliding unit allows long sessions virtually without interruption.
- The 4.5 mm stroke is fixed on this version, but drive units with other strokes are sold separately: the control unit remembers the settings for each, and swapping is done with two clicks.
- If you also do fine lines or details, combine this machine with a shorter stroke drive unit instead of forcing the 4.5 mm on lining.
- Adjust the brightness and orientation of the screen in settings, so you can read the parameters comfortably regardless of how you hold the machine in your hand.
- Test the Responsive modes versus Steady mode on synthetic skin before using on clients, to feel the difference in behavior for each technique.
- Use the included sturdy transport case when traveling (conventions, guest spots) — it protects the machine, batteries and charging station.
- Check the battery connector and contacts periodically and keep them clean — a good connection means stable operation throughout the session.
Warning: The tattoo machine cannot be sterilized by immersion in liquids — never put it in an autoclave or under running water. Protect it at every session with disposable barriers (machine wrap/sleeve) and work exclusively with sterile, disposable needle cartridges opened in front of the client. Disposable grips are thrown away after each client, and the machine surfaces are decontaminated with disinfectant products suitable for electronic equipment, according to the manufacturer's instructions. Wear gloves throughout the work and follow the hygiene and cross-contamination prevention standards valid in professional studios. The equipment is intended for professional tattoo artists, not for home use.
Frequently asked questions
What techniques is the 4.5 mm stroke designed for?▾
The long 4.5 mm stroke offers a longer needle travel and a more pronounced impact, which helps to saturate color quickly and evenly in the skin. It is the preferred configuration for shading, color packing, realism, portraits and work with large areas of color and shading, where it reduces the number of necessary passes.
Can I use this machine also for lining?▾
You can, but 4.5 mm is not the optimal stroke for fine lines and details — for lining, shorter strokes (2.5 mm or 3.5 mm) are recommended. The advantage of the Unlimited II system is that drive units are interchangeable: you buy the unit with the desired stroke separately and change it in two clicks, and the machine remembers the settings for each stroke.
How long does the battery last and what do I get in the package?▾
With the standard Keeppower 18500 batteries of 2000 mAh you get over 5 hours of autonomy, with only about 2 hours of charging when using a QC3.0 5V source with at least 1.8A. In the package you receive 2 fast-charging Li-ion batteries, the charging station, the cable and a sturdy transport case. The battery is quickly changed via the sliding unit, so you can continue the session almost immediately.
What grips is it compatible with?▾
It is compatible with all SOL Nova grips, as well as Disposable Grips One Inch and Ergo Round. Thus you can choose your preferred ergonomics: reusable grips maintained according to the manufacturer's instructions or disposable grips that you throw away after each client — the simplest option from a hygiene standpoint.
How do I properly maintain and sanitize the machine between clients?▾
The body of the machine is not sterilized and does not get wet: you protect it during work with disposable barriers, and between clients you decontaminate surfaces with disinfectant suitable for electronic equipment, according to the manufacturer's instructions. Needle cartridges and disposable grips are used once and disposed of properly. Keep the battery contacts clean and store the machine in the transport case when not in use.
Is it a suitable choice for beginners?▾
It is a premium professional device with a 24-month warranty, designed primarily for artists who work regularly and know their techniques. A beginner can use it — the operating modes and screen make it intuitive — but the fixed 4.5 mm stroke is specialized for shading and color, not a 'one-size-fits-all' stroke. If you are a beginner and want a single versatile configuration, discuss with us before choosing; the system with interchangeable drive units allows you to expand later anyway.

Cheyenne Sol Nova Unlimited II 4.5mm is the long-stroke variant of the most advanced wireless tattoo machine, manufactured in Germany. The 4.5mm stroke is optimized for shading, color packing, and techniques requiring deeper penetration and superior impact power. Equipped with an integrated OLED display, 3 control buttons, and the revolutionary quick battery-swap system, Unlimited II 4.5mm offers unprecedented control. The Keeppower 18500 2000mAh battery ensures over 5 hours of autonomy. Drive units are interchangeable - you can switch between 2.5mm, 3.5mm, and 4.5mm in two clicks, and the control unit memorizes settings automatically. The 4.5mm stroke is the preferred choice for artists specializing in realism, portraits, and work with large areas of color and shading. The more pronounced needle impact facilitates rapid, uniform color saturation in the skin. The OLED display enables real-time monitoring of frequency, operating mode, and battery level. Compatible with all Cheyenne Disposable Grips for personalized ergonomics. Construction from premium German materials guarantees long-term reliability and resistance to wear under intensive professional use conditions. Ergonomics remain identical to shorter stroke variants, ensuring familiar comfort regardless of the chosen configuration. The rapid battery-swap system enables fluid transitions between sessions without significant downtime. Artists specializing in realism and color work particularly appreciate the 4.5mm stroke performance, which reduces the number of passes needed for complete color saturation.
Frequently Asked Questions What techniques is the 4.5mm stroke ideal for? The 4.5mm stroke is optimized for shading, color packing, and techniques requiring superior impact power. It is ideal for realism, portraits, large color areas, and any work requiring rapid, uniform color saturation in the skin over large surfaces. Can I use 4.5mm for lining too? While 4.5mm can be used for lining, it is not the optimal stroke for fine lines and details. For lining, the 2.5mm or 3.5mm stroke is recommended. The advantage of the Unlimited II system is that you can quickly switch the Drive unit between sessions to adapt the stroke to the technique. What is the performance difference between 3.5mm and 4.5mm? The 4.5mm stroke offers a longer needle travel, meaning more pronounced impact and deeper penetration. This translates to faster, more uniform color saturation, ideal for shading and color packing. The 3.5mm stroke is more versatile, suitable for both lining and shading. Can I purchase just the 4.5mm Drive unit separately? Yes, Drive units are available separately, allowing you to extend your machine's versatility without purchasing a second complete device. You can start with one stroke and add others later. The control unit memorizes settings for each connected stroke. How long does the battery last on the 4.5mm model? The Keeppower 18500 2000mAh battery provides over 5 hours of continuous work on a single charge. Consumption may vary slightly depending on selected voltage and work intensity. With spare batteries, autonomy is practically unlimited throughout the day. Does the OLED display work the same as on the 3.5mm model? Yes, the OLED display is part of the control unit which is common to all stroke variants. It displays the same real-time information: working frequency, active operating mode, and battery level. The interface is identical regardless of the connected Drive unit. Is the Sol Nova Unlimited II 4.5mm heavier than the 3.5mm model? The weight difference between stroke variants is negligible as only the Drive unit differs, with all other components being identical. Both variants maintain the reduced weight and excellent ergonomics characteristic of the Sol Nova Unlimited II range. Is 4.5mm suitable for beginners? The 4.5mm stroke requires experience in pressure and technique control as the more pronounced needle impact can cause skin trauma if not properly managed. Beginners are recommended to start with the 3.5mm stroke and transition to 4.5mm as they accumulate experience. What additional accessories does the machine need? Sol Nova Unlimited II 4.5mm comes with the machine, 2 batteries, and charging dock. Additionally, you need Cheyenne Disposable Grips and compatible Cheyenne Safety needle cartridges or similar. Extra spare batteries are recommended for uninterrupted sessions. Can the machine also be used with a cord? Sol Nova Unlimited II is designed as a wireless machine and does not feature corded connectivity. The over 5-hour battery autonomy and quick battery-swap capability eliminate the need for corded power. For the corded variant, check the standard Sol Nova.
