WARNING: This product contains nicotine. Nicotine is an addictive chemical. For adults 21 and over only. See our age verification and responsible use policy.

Quick answer: For adults 21+ who already use nicotine and are new to vaping devices: the simplest start is a disposable, which comes charged and filled. A pod kit costs more up front but uses cheaper replaceable pods. Nicotine strength is shown as a percent or mg/mL (5% is about 50 mg/mL), and most disposables are 5%. Draw slowly and steadily, don't chain puff, keep devices out of heat, and charge rechargeable models with a proper cable. This guide makes no health claims; it covers how the devices work.

Starting with a disposable?

They come charged and filled; no setup.

In this guide

Choose a device type

Type	How it works	Good for
Disposable	Pre-filled, pre-charged; use until empty	The simplest start
Rechargeable disposable	Disposable with a USB-C port	Longer life per device
Pod kit	Battery plus replaceable or refillable pods	Lower cost over time
Sub-ohm kit	Larger device, adjustable wattage	Experienced users wanting big vapor

More: rechargeable vs non-rechargeable disposables and the sub-ohm guide.

Understand nicotine labels

Strength appears as a percent or mg/mL. Multiply the percent by 10 to get mg/mL: 5% is about 50 mg/mL, 2% about 20 mg/mL. Most disposables are 5%. Zero-nicotine options are labeled 0%.

How to vape

Check the device is charged and the airflow is clear.
Draw slowly and steadily for 2 to 3 seconds.
Most disposables fire automatically when you inhale.
Rest between puffs instead of chain puffing.
Stop if the device gets hot or tastes burnt.

Pick a flavor

Start with a flavor family you know you like. See the disposable vape flavor guide.

Charging and storage

Charge rechargeable models with a proper USB-C cable and a standard adapter.
Never charge a disposable without a charging port.
Keep devices out of hot cars and direct sun.
Store away from children and pets.

Common beginner mistakes

Mistake	What happens	Fix
Chain puffing	Burnt taste, shorter life	Rest between puffs
Leaving it in a hot car	Leaks, battery damage	Carry it with you
Wrong charger	Battery damage	Use a standard adapter
Buying fakes from unknown sellers	Poor taste, early failure	Buy from an authorized store; check the code
Expecting the full puff count	Device "dies early"	Puff counts are estimates

Age and buying online

You must be 21 to buy. Online orders are age-verified and need an adult signature at delivery. See how old you have to be to buy a vape and our age verification policy.

How a vape works

Every vape has the same four parts: a battery, a coil (the heating element), a wick that holds e-liquid against the coil, and the e-liquid itself. When you inhale, a sensor or button sends power to the coil, the coil heats the liquid in the wick, and the vapor travels through the mouthpiece. Disposables hide all four parts in one sealed body; pod kits put the coil and liquid in a replaceable pod that clicks onto a reusable battery.

Part	What it does	In a disposable	In a pod kit
Battery	Powers the coil	Built in; some recharge	Reusable, rechargeable
Coil	Heats the e-liquid	Built in	Inside the pod or a replaceable coil
Wick	Feeds liquid to the coil	Built in	Inside the pod
E-liquid	Makes the vapor and carries flavor and nicotine	Prefilled	Prefilled or refillable pods

Disposables, pod kits and sub-ohm kits compared

A disposable is the lowest-effort option: no charging on many models, no refilling, and you replace it when the liquid or battery runs out. Rechargeable disposables add a USB-C port so the battery lasts as long as the liquid. Pod kits cost more at the start, but each replacement pod costs less than a new disposable, and the battery lasts for months. Sub-ohm kits are larger, use lower-strength freebase e-liquid at higher power and suit experienced users who want big vapor.

	Disposable	Pod kit	Sub-ohm kit
Upfront cost	Lowest	Medium	Highest
Ongoing cost	A new device each time	Replacement pods	E-liquid and coils
Setup	None	Insert a pod	Fill tank, set wattage
Nicotine type	Mostly salt nic	Mostly salt nic	Mostly freebase
Best for	Simplicity	Lower cost over time	Experienced users

Nicotine salt vs freebase

Nicotine salt is the form used in most disposables and pod kits; it is made for low-power devices and is sold at higher strengths, commonly 2% to 5%. Freebase nicotine is used in larger, higher-power devices at lower strengths, commonly 0.3% to 1.2%. The two are not interchangeable: high-strength salt nic is not meant for sub-ohm tanks. Strengths are printed on every box and product page, and zero-nicotine options are labeled 0%.

Want something refillable?

Pod kits use replaceable pods.

Draw styles: mouth to lung and direct to lung

Most disposables and pod kits are built for mouth-to-lung (MTL) draws: you draw vapor into your mouth first, similar to a cigarette, with a tighter airflow. Sub-ohm kits are built for direct-to-lung (DTL) draws with open airflow. Using the draw style a device is designed for gives better flavor and fewer dry hits. Some devices have an airflow slider so you can make the draw tighter or looser.

Reading a product page

Spec	What it tells you
Rated puff count	The maker's estimate of puffs; real use varies
E-liquid volume (mL)	How much liquid is inside; a better guide to how long it lasts
Nicotine strength (%)	How much nicotine per mL
Battery (mAh)	Battery capacity; bigger lasts longer per charge
Charging	USB-C rechargeable or not
Modes or screen	Power modes and a display for battery and liquid

Buying authentic devices

Buy from a store that lists its age-verification and shipping policies.
Check that packaging is sealed and printed cleanly.
Use the brand's authentication code or scratch-off where the box has one.
Be wary of prices far below other stores.

Getting rid of used devices

Disposables contain lithium batteries, so don't throw them in the household trash or curbside recycling. Most cities and counties accept them at household hazardous waste collection sites; check your local solid waste agency.

Traveling with a vape

Vapes go in your carry-on, never checked bags, and can't be used or charged on a plane. Full rules: can you bring a vape on a plane.

Charging a rechargeable disposable, step by step

Use the USB-C cable that came with it, or a good-quality replacement.
Plug into a standard 5-volt phone-type adapter, not a fast charger unless the maker allows it.
Charge on a hard surface where you can see it.
Unplug when the light or screen shows full, usually within an hour.
Never charge a device with no charging port, or one that is damaged, wet, swollen or hot.

Common first-week problems and fixes

Problem	Likely cause	Fix
No vapor	Battery low or device locked	Charge it; check for a lock mode in the instructions
Burnt taste	Chain puffing or the device is empty	Rest between puffs; replace if empty
Gurgling	Condensation in the mouthpiece	Tap it gently and wipe the mouthpiece
Weak flavor	Low battery or low power mode	Charge or switch modes
Leaking	Heat or pressure change	Keep it upright and out of heat

More: why your disposable vape tastes burnt.

Storage and care

Keep devices at room temperature, out of direct sun and never in a parked car, where heat can damage the battery and make the liquid leak. Store them away from children and pets, because e-liquid contains nicotine, which is toxic if swallowed. Keep spare devices in their boxes until you use them, and don't carry them loose with keys or coins.

Frequently asked questions

What is the easiest vape for a beginner?

A disposable: it comes charged and filled, with no setup. A rechargeable disposable lasts longer per device.

What is the difference between a disposable and a pod kit?

A disposable is used until empty and replaced whole; a pod kit keeps a rechargeable battery and replaces only the pod, which costs less over time.

What does 5% nicotine mean?

About 50 mg of nicotine per mL of e-liquid. Multiply the percent by 10 to get mg/mL.

How do I use a disposable vape?

Draw slowly and steadily for 2 to 3 seconds. Most disposables fire automatically when you inhale; some have a button or a lock mode.

Why does my vape taste burnt?

Usually chain puffing, which dries the wick, or a device that is nearly empty. Rest between puffs and replace an empty device.

How long does a disposable last?

It depends on the e-liquid volume, how long each puff lasts and the battery. Rated puff counts are estimates; e-liquid volume is a better guide.

Can I charge any disposable?

Only ones with a charging port, usually USB-C. Never try to charge a disposable that has no port.

What flavor should I start with?

A flavor family you already like from foods and drinks. Our flavor guide explains each family.

Do I need to be 21 to buy?

Yes.

Why does my order need a signature?

The federal PACT Act requires age verification at checkout and an adult 21+ signature with ID at delivery.

Are there zero-nicotine vapes?

Yes, labeled 0%.

How do I avoid fake vapes?

Buy from a store with clear age-verification and shipping policies, check that packaging is sealed, and use the brand's authentication code where available.
