Yocan Uni Pro 510 Cart

Yocan UNI Pro 510 Cartridge Battery

The Yocan UNI Pro is a versatile, compact 510-thread cartridge battery designed for customers who want precise voltage control, excellent cartridge compatibility and straightforward operation.

Building upon the success of the original Yocan UNI, the UNI Pro introduces an OLED display, adjustable voltage from 2.0V to 4.2V, a convenient 10-second preheat function and Yocan's patented adjustable cartridge chamber.

Its standout feature is its ability to accommodate a wide variety of 510-thread oil cartridges.

Unlike conventional pen-style batteries, which leave the cartridge exposed and provide limited adjustment, the UNI Pro uses a concealed cartridge chamber with adjustable height and diameter settings.

A rotating dial changes the width of the cartridge opening, while a height adjustment slider raises or lowers the installed cartridge.

This allows customers to customise the fit for compatible cartridges of different shapes and sizes.

The UNI Pro also features a magnetic 510-thread connection, making cartridge installation and removal quick and convenient.

Instead of repeatedly screwing cartridges directly into the battery, simply attach the supplied magnetic adapter to your compatible cartridge and lower it into the chamber.

Another major advantage is its precision voltage control.

With an adjustable output of 2.0V to 4.2V in 0.1V increments, the UNI Pro provides far greater flexibility than batteries with only three or four preset voltage settings.

Lower voltages are generally preferred for gentler heating and flavour-focused sessions, while higher voltages can provide more intensive heating when suitable for the cartridge.

The clear OLED display shows essential information, including the selected voltage, battery level and cartridge resistance.

A 10-second preheat function helps warm thicker oils before normal operation, while the integrated 650mAh rechargeable battery provides convenient cordless use.

With its durable construction, compact dimensions and simple button controls, the Yocan UNI Pro remains an excellent choice for customers seeking an adjustable 510 cartridge battery.

Adjustable Cartridge Height and Width

The Yocan UNI Pro's defining feature is its patented adjustable cartridge chamber.

Many 510 batteries are limited by the size or shape of the cartridge they can accommodate.

The UNI Pro addresses this problem by allowing users to adjust both the chamber width and cartridge height.

Adjustable Cartridge Diameter

The rotating adjustment dial controls the width of the cartridge chamber.

Turning the dial allows the opening to expand or contract around a compatible cartridge.

This helps hold cartridges of different diameters securely.

Adjustable Cartridge Height

A slider on the side of the device raises or lowers the installed cartridge.

This allows customers to adjust how much of the cartridge extends above the battery housing.

Cartridge Compatibility

The original UNI Pro manual specifies compatibility with cartridges measuring approximately:

These are manufacturer specifications rather than a guarantee that every cartridge will fit.

Cartridges with unusual mouthpieces, oversized tanks or incompatible electrical characteristics may not be suitable.

Why Is This Useful?

Greater compatibility: Accommodates many common 510 cartridge designs.

Customised fit: Adjust the chamber around the cartridge.

Improved stability: Helps reduce movement inside the housing.

Protected construction: Much of the cartridge sits inside the device.

Long-term flexibility: Change between compatible cartridges without purchasing another battery.

Does the UNI Pro Fit Every 510 Cartridge?

No.

Although the UNI Pro is marketed as a universal cartridge battery, compatibility still depends on cartridge dimensions, resistance and construction.

Always check that your cartridge is compatible before use.

Precision Variable Voltage – 2.0V to 4.2V

One of the biggest improvements over the original Yocan UNI is the introduction of precision voltage control.

The UNI Pro allows customers to adjust the output between 2.0V and 4.2V in increments of just 0.1V.

This provides significantly more flexibility than conventional 510 batteries with a small selection of preset settings.

Why Does Voltage Matter?

Voltage affects the electrical power delivered to a compatible cartridge's heating element.

In general, increasing voltage increases heating power, although the actual temperature also depends on cartridge resistance, coil construction and airflow.

Lower voltage settings are often preferred for gentler heating.

Higher settings may produce more vapour but can also overheat certain cartridges or their contents.

Suggested Voltage Guide

These are general operating ranges, not universal recommendations for every cartridge.

Always follow the cartridge manufacturer's voltage guidance.

What Voltage Do We Recommend?

For customers using a new compatible cartridge, we recommend starting at a low voltage within its manufacturer's permitted range.

Increase gradually only if necessary.

This helps avoid unnecessary overheating.

How Do You Adjust the Voltage?

Use the dedicated + and − buttons below the OLED display.

Each press changes the output by 0.1V.

Does the UNI Pro Have Temperature Control?

No.

The UNI Pro provides precise voltage control, not direct temperature control.

The display shows the selected voltage rather than a measured cartridge temperature.

OLED Display

The Yocan UNI Pro features a clear OLED screen that provides useful information during operation.

This is one of the most important upgrades over the original UNI.

What Does the OLED Display Show?

Selected voltage: The current power setting.

Battery level: Remaining battery charge.

Cartridge resistance: The resistance detected from the connected cartridge.

Puff information: Operating information, including puff duration and a puff counter on supported versions.

Device warnings: Messages relating to certain connection or operating problems.

Benefits of the OLED Display

Precise adjustment: See exactly which voltage is selected.

Battery monitoring: Helps prevent unexpected loss of power.

Compatibility information: Resistance readings can assist with identifying connection issues.

Easy operation: No need to memorise LED colour codes.

Is the Screen Easy to Use?

Yes.

The power button and voltage adjustment buttons are positioned together on the front of the device.

This makes the UNI Pro particularly approachable for customers who are new to variable-voltage cartridge batteries.

10-Second Preheat Function

The UNI Pro includes a convenient 10-second preheat mode.

This function is designed to warm the connected cartridge gently before normal use.

Why Is Preheating Useful?

Some cartridge oils become more viscous at lower temperatures.

This can make it more difficult for the material to flow towards the heating element.

A brief preheat may help warm the cartridge and improve the flow of compatible oils.

How Do You Activate Preheat?

Press the power button twice quickly.

The UNI Pro begins its 10-second preheat cycle.

The display indicates that the device is warming.

Can You Stop Preheat Early?

Yes.

Press the power button twice again to cancel the cycle.

Do You Need to Preheat Every Time?

No.

Preheat is optional.

It may be useful with thicker oils, but repeated unnecessary heating can affect cartridge contents.

Follow the cartridge manufacturer's instructions.

Magnetic 510 Cartridge Connection

The Yocan UNI Pro uses a magnetic cartridge adapter.

This provides a convenient alternative to batteries where the cartridge must be screwed directly into the main housing.

How Does the Magnetic Connection Work?

Attach the supplied 510-thread magnetic adapter to the base of a compatible cartridge.

Lower the cartridge into the UNI Pro's chamber.

The magnetic connection holds the cartridge in place and provides the electrical contact.

Benefits of the Magnetic Adapter

Quick installation: Easily insert and remove cartridges.

Reduced handling: Less need to repeatedly thread cartridges into the device.

Convenient swapping: Useful when changing between compatible cartridges.

Secure connection: Magnetic contact keeps the cartridge seated.

Is the Magnetic Adapter Included?

Yes.

The standard Yocan UNI Pro kit includes one magnetic 510 adapter.

Can You Buy Replacement Adapters?

Compatible replacement magnetic adapters are available separately.

We recommend keeping a spare if you regularly use multiple cartridges.

Can You Leave the Adapter Attached?

Yes, provided it is stored safely and the electrical contacts remain clean and undamaged.

Concealed Cartridge Design

Unlike a traditional pen-style 510 battery, the UNI Pro houses most of the cartridge inside its body.

This provides a compact appearance and additional protection against everyday knocks.

Benefits of the Recessed Chamber

Reduced exposure: Much of the cartridge is surrounded by the battery housing.

Compact profile: Creates a discreet box-mod design.

Better stability: Adjustable chamber helps support the cartridge.

Convenient handling: Comfortable, palm-sized construction.

Oil-Level Viewing Window

The UNI Pro includes a viewing window on the side of the housing.

This allows customers to check the contents of many compatible cartridges without removing them.

Visibility depends on cartridge dimensions, material and the selected height position.

Does the UNI Pro Completely Hide the Cartridge?

Not necessarily.

The amount of cartridge visible above the housing depends on its size and height adjustment.

Integrated 650mAh Battery

The Yocan UNI Pro is powered by a 650mAh rechargeable lithium-ion battery.

This provides portable operation without requiring a separate battery cell.

Benefits of the Battery

Rechargeable: Suitable for repeated use.

Compact: Supports the small box-mod design.

Cordless operation: Convenient away from home.

Battery display: OLED screen provides charge information.

How Long Does the Battery Last?

Battery endurance depends on the selected voltage, cartridge resistance, activation duration and battery condition.

Lower-voltage use generally consumes less power than higher-voltage operation with the same compatible cartridge.

Because usage patterns vary, there is no single reliable number of puffs per charge.

Is the Battery Removable?

No.

The 650mAh battery is integrated and is not intended for routine user replacement.

USB Charging – Important Version Information
