• USB-C Charging Cable
• User Guide

Getting Started

Initial Charge

Before first use, fully charge your Vessel Core:

1. Locate the USB-C charging port on the battery
2. Connect the included USB-C cable to the battery
3. Connect the other end to a USB power source (5V/1A recommended)
4. The LED indicators will illuminate during charging
5. When fully charged, the LEDs will turn off or show full status
6. Initial charge takes approximately 60-90 minutes

Tip: Always complete the initial charge before first use for optimal battery performance.

Attaching a Cartridge

The Core features a wide 510 crown designed to accommodate cartridges of various diameters:

1. Ensure the battery is powered off (recommended during cartridge changes)
2. Hold the cartridge by its body, not the mouthpiece
3. Align the cartridge's 510 threading with the Core's crown
4. Gently screw clockwise until snug
5. Do not overtighten—stop when you feel resistance

The wide crown design ensures your cartridge sits flush and secure regardless of its diameter, eliminating the wobble common with narrower battery connections.

Powering On/Off

• Turn On: Click the button 5 times rapidly within 2 seconds
• Turn Off: Click the button 5 times rapidly within 2 seconds
• The LED indicators will flash to confirm the power state change

Always power off your Core when not in use to conserve battery life and prevent accidental activation.

Voltage Settings

The Vessel Core offers four voltage settings to customize your vaping experience. Access and cycle through settings by clicking the button 3 times rapidly.

Understanding Each Voltage Level

Voltage	Best For	Experience
2.4V	Thin oils, flavor focus	Ultra-smooth, maximum terpene expression
2.8V	Standard cartridges	Balanced flavor and vapor
3.2V	Medium-thick oils	Enhanced vapor, good flavor
3.6V	Thick concentrates	Maximum vapor production

Voltage Selection Tips

• Start low: Begin at 2.4V or 2.8V and increase if needed
• Match your oil: Thinner oils work best at lower voltages
• Flavor vs. vapor: Lower voltages prioritize flavor; higher voltages increase vapor
• Cartridge life: Lower voltages extend cartridge longevity
• Live resin: Use 2.4V-2.8V to preserve delicate terpenes

Identifying Current Voltage

The 3-LED indicator system shows your current voltage level when you cycle settings. Each voltage level has a distinct LED pattern. Refer to the LED section below for details.

Usage Instructions

Basic Operation

1. Power on the Core (5 clicks)
2. Select your preferred voltage (3 clicks to cycle)
3. Hold the button while inhaling from your cartridge
4. Release the button when finishing your draw
5. The LED illuminates during use

Tips for Best Results

• Slow and steady: Take smooth, consistent draws for 3-5 seconds
• Pause between puffs: Wait 15-30 seconds between draws to prevent overheating
• Start low: Begin at lower voltages and increase as needed
• Preheat thick oils: For viscous concentrates, hold the button briefly (1-2 seconds) before inhaling
• Store upright: Prevents oil from settling in unwanted areas

Understanding the LED Indicators

The Core's 3-LED display system provides visual feedback:

• During power on/off: LEDs flash to confirm state change
• While vaping: LEDs illuminate to show operation
• Voltage change: LED pattern indicates current voltage setting
• Low battery: Fewer LEDs illuminated or flashing during use
• Charging: LEDs show charging progress

Charging

How to Charge

1. Power off the Core (recommended but not required)
2. Connect the USB-C cable to the battery's charging port
3. Connect the other end to a USB power source
4. LED indicators show charging status
5. Full charge takes approximately 60-90 minutes
6. LEDs indicate full charge when complete

Charging Best Practices

• Use the included USB-C cable or a quality replacement
• Use a standard 5V/1A USB power source
• Avoid fast chargers rated above 5V/2A
• Do not leave charging unattended overnight
• Charge before the battery is completely depleted
• Avoid charging in extreme temperatures

Battery Life Expectations

With the 260mAh capacity, expect:

• Light users (10-15 puffs/day): 2-3 days between charges
• Moderate users (20-30 puffs/day): 1-2 days between charges
• Heavy users (40+ puffs/day): Daily charging required

Battery life varies based on voltage setting, draw duration, and cartridge resistance. Higher voltage settings consume more power per puff.

Care & Maintenance

Regular Cleaning

Maintain your Core's performance with routine cleaning:

Weekly:

1. Remove the cartridge
2. Use a dry cotton swab to clean the 510 threading
3. Wipe any oil residue from the crown area
4. Clean the button area to prevent sticking
5. Wipe the exterior with a soft, dry cloth

Monthly:

1. Perform weekly cleaning steps
2. Use isopropyl alcohol (90%+) on a cotton swab for stubborn residue
3. Allow all components to dry completely before use
4. Inspect the charging port for debris

Storage Guidelines

• Store in a cool, dry environment
• Avoid direct sunlight and heat sources
• Keep away from water and moisture
• Store with 40-60% charge for extended periods
• Remove cartridge for long-term storage
• Use a Vessel Rover case for protection (sold separately)

Temperature Considerations

• Operating range: 50°F-85°F (10°C-30°C)
• Storage range: 32°F-95°F (0°C-35°C)
• Avoid: Leaving in hot cars, direct sunlight, freezing temperatures

What to Avoid
