How to Use a City Trees Disposable Vape Pen

How It Works, How to Activate It, and What to Do If It Won’t Hit

City Trees disposable vape pens are designed to be simple, convenient, and ready to use straight out of the package. However, many first-time users are unsure how to activate them, whether they need to be turned on, or why the device sometimes does not produce vapor right away.

This guide explains how a City Trees disposable vape works, how to use it correctly, how to activate it, and what to do if your disposable pen is not hitting as expected.

Key Takeaways – Using City Trees Disposable Vape Pen

• City Trees disposable vapes are draw-activated and require no buttons
• Activation happens automatically when you inhale
• Gentle puffs work better than forceful ones
• Most performance issues are caused by airflow blockage, temperature, or battery limits
• When the device stops producing vapor, replacement is the safest option

What Is a City Trees Disposable Vape Pen? (Expanded)

A City Trees disposable vape pen is a ready-to-use, single-use vaping device that comes pre-filled with vape oil/e-liquid and pre-charged with a built-in battery. The key idea behind a disposable pen is convenience: you do not need to assemble parts, refill liquid, replace coils, or adjust power settings.

What “Disposable” Actually Means

“Disposable” usually refers to two limits:

1. The liquid supply is fixed (you can’t refill it safely)
2. The battery lifespan is limited (once it’s depleted, performance drops or stops)

When either the oil runs out or the battery can no longer provide enough power, the device is considered “finished” and is meant to be replaced.

What You’ll Usually See on a City Tree’s Disposable

While designs vary by model and batch, most disposable pens share a similar outer layout:

• Mouthpiece/tip: where you inhale
• Main body: holds the internal chamber and battery
• Airflow holes: tiny openings (often at the bottom or side) that allow air to travel through the device
• Optional LED light: Some models include a small light that indicates activation or battery status, but not all do

Common Characteristics of Disposable Vape Pens

Most City Trees disposable pens typically:

• Arrive fully assembled and ready for immediate use
• Have no buttons (or no adjustable settings), which reduces user error
• Use draw activation, meaning the device turns on when you inhale
• Are designed for consistent, low-power vapor output rather than customization

Why Beginners Prefer Disposables

Disposables are often chosen because they remove common learning steps:

• No wattage/temperature settings
• No coil replacement
• No tank filling
• No troubleshooting with mods

Practical expectation: Disposables are designed for simplicity, but the tradeoff is that you have less control over airflow, power, or performance tuning compared to refillable devices.

Tip: Before first use, always check for transport plugs (silicone caps) and airflow stickers. These are a very common reason a disposable “won’t hit” right out of the box.

How Does a City Trees Vape Work? (Expanded)

City Trees disposable vape pens work using a simple closed system that converts stored liquid into an inhalable aerosol (often called “vapor”) using battery-powered heating. The device activates automatically when it detects airflow from your inhale.

The Key Internal Components (And What Each One Does)

Most disposable pens contain these parts:

1. Battery
   1. A small lithium battery provides power for a limited number of heating cycles
   2. Battery strength affects vapor production: as it weakens, the device may produce less vapor or weaker flavor
2. Airflow Sensor / Draw Sensor
   1. Detects pressure change when you inhale
   2. Signals the device to deliver power to the heating element
   3. This is why gentle, steady pulls usually work better than short, sharp puffs
3. Heating Element (Coil or Mesh Coil)
   1. A metal coil or mesh heats up rapidly when powered
   2. Its job is to warm the liquid at the wick surface so it can aerosolize
   3. If the coil overheats or the wick is under-supplied, flavor may drop or taste harsh
4. Wick (Cotton or Similar Material)
   1. The wick is a porous material that feeds liquid to the coil
   2. It controls how evenly the liquid is delivered to the heating surface
   3. Dry or partially saturated wick = weak vapor or inconsistent flavor
5. Pre-Filled Liquid Chamber
   1. Holds the oil/e-liquid
   2. Liquid slowly moves toward the wick through capillary action
   3. Temperature changes can affect viscosity (cold = thicker, slower flow)
6. Airflow Path (Air Channel)
   1. The internal “tunnel” that air travels through when you inhale
   2. Condensation can collect here and cause clogging or restricted hits over time

What Happens When You Take a Puff (Step-by-Step)

When you inhale through the mouthpiece:

1. Air enters through airflow holes at the base/side
2. The airflow sensor detects the inhalation and activates the circuit
3. The battery sends power to the coil/mesh for a short burst
4. The coil heats the liquid-saturated wick surface
5. Liquid turns into aerosol and moves up the airflow path
6. You inhale the aerosol through the mouthpiece

This cycle repeats each time you puff until the oil is depleted or the battery can no longer sustain the heating process.

Why the First Few Puffs Can Feel Light

A “weak” first hit can happen because:

• The wick needs a moment to fully stabilize the liquid flow
• The device may have been stored cold (thicker liquid)
• Some designs require a couple of gentle puffs for consistent output

This is often normal and not automatically a defect.

Why a Disposable Sometimes Stops Hitting

Performance drops usually come from one of these:

• Airflow obstruction (condensation in the mouthpiece or air channel)
• Oil flow issues (very thick oil, cold conditions, or storage position)
• Battery depletion (insufficient power to heat properly)
• End-of-liquid (device may still “activate,” but vapor is minimal)

Tip: If a disposable is not hitting, always check simple things first:

• Any silicone plug still inside the mouthpiece
• Any sticker blocking airflow holes
• Condensation clogging the mouthpiece opening
• Cold temperature (let it sit at room temp)

How Do You Activate a Disposable Vape?

Most City Trees disposable vape pens are automatically activated by inhaling, not by pressing a button.

To activate the device:

1. Remove the vape from its packaging.
2. Take off any protective silicone caps or rubber plugs.
3. Make sure no stickers or seals are covering the airflow holes.
4. Inhale gently through the mouthpiece.

If the device is functioning properly, it should produce vapor immediately or within the first few puffs.

How to Turn On a City Trees Disposable Vape

A common question is whether City Trees disposables need to be “turned on.”

In most cases, there is no on/off switch. The device turns on automatically when you inhale and turns off when you stop.

This means:

• You do not need to press a button.
• You do not need to hold anything down.
• There are no settings to adjust.

If nothing happens when you inhale, it usually indicates an airflow issue, temperature issue, or battery-related limitation—not that the device is “off.”

How to Use a City Trees Disposable Vape Pen (Step-by-Step)

Step 1: Inspect the Device

Before using the vape:

• Check that the mouthpiece is clear.
• Remove all packaging materials.
• Ensure the oil chamber looks intact and not leaked.

If the device was shipped in cold conditions, allow it to reach room temperature before use.

Step 2: Take the First Puff Correctly

For best results:

• Take a slow, steady inhale lasting about 2–3 seconds.
• Avoid sharp or forceful pulls.
• Do not inhale continuously.

Disposable vapes are designed for gentle airflow. Pulling too hard can restrict vapor production or draw excess condensation into the airflow path.

Step 3: Allow the Device to Warm Up

The first few puffs may feel lighter than expected. This is normal.

The oil and heating element may need a few activations to stabilize, especially if the device has been sitting unused. After a few gentle puffs, vapor production typically becomes more consistent.

How Do I Get My Disposable Pen to Hit?

If your City Trees disposable vape is not producing vapor, try the following troubleshooting steps.

Check for Airflow Blockage

Condensation can collect inside the mouthpiece and block airflow.

What to do:

• Remove the mouthpiece cap.
• Gently tap the device mouthpiece down on a paper towel.
• Wipe the mouthpiece opening with a dry cotton swab.

Avoid inserting sharp objects into the device.

Check Temperature Conditions

Cold temperatures can thicken the oil, making it harder to vaporize.

If the vape feels cold:

• Hold it in your hands for a few minutes.
• Let it sit at room temperature.
• Avoid using it immediately after being outdoors in cold weather.

Once the oil warms up, vapor production often improves.

Check Battery Status

Disposable vapes have limited battery capacity. If the battery is depleted:

• The device will not produce vapor.
• There is no way to recharge non-rechargeable disposables.
• The device must be replaced.

Some disposables include a small LED light. If it does not activate or flashes irregularly, it may indicate the battery is exhausted.

Common Reasons a City Tree’s Disposable Won’t Hit

The most common causes include:

• A protective plug was not removed
• Condensation blocking airflow
• Cold-thickened oil
• The oil has been fully used
• The battery has reached the end of its lifespan
• The device was stored on its side or upside down

In most cases, gentle troubleshooting resolves the issue unless the disposable has reached the end of its use.

Tips for Getting the Best Performance From a City Trees Disposable

• Store the device upright when possible
• Avoid chain vaping
• Take smooth, slow puffs
• Keep the device at room temperature
• Clean the mouthpiece regularly
• Do not cover airflow holes while inhaling

Following these habits helps extend consistent performance during the device’s lifespan.

When It’s Time to Replace the Disposable Vape

A City Trees disposable vape should be replaced when:

• Vapor production stops completely
• The flavor becomes consistently weak or unpleasant
• You need to inhale very hard to get vapor
• The device becomes unusually warm
• No LED response is visible (if applicable)

Disposable vapes are not designed to be repaired or refilled.
