Pen-style batteries represent one of the simpler forms of rechargeable vape hardware. Instead of the larger body and extensive controls found on a box mod, the battery is housed inside a narrow cylindrical casing that sits directly beneath a compatible tank or clearomiser.
The end result is a compact device that feels much closer in shape to a traditional vape pen.
Our current range is particularly focused on the KangerTech EVOD battery series, including fixed-voltage and variable-voltage models in several battery capacities. These remain useful for anyone maintaining an existing EVOD-style setup or looking for a straightforward battery to pair with compatible low-powered tanks.
A pen style vape battery is essentially the rechargeable power section of a vape pen.
Rather than being supplied as a complete kit with a tank already included, these products are generally sold as standalone batteries. You can then attach a compatible tank, clearomiser or atomiser to create a complete device.
The battery supplies power to the coil inside the attached tank. Depending on the model, that output may be fixed automatically or adjustable by the user.
Most pen batteries keep controls deliberately simple. A typical design may include:
That simplicity is a large part of their appeal. There are fewer menus and settings to manage than you'd normally find on a modern regulated box mod.
KangerTech EVOD batteries make up the majority of our current pen-style battery selection.
The EVOD platform is based around a traditional slim cylindrical design and is intended for use with compatible eGo and 510-style tanks and clearomisers. For example, the KangerTech EVOD 1000mAh battery provides a constant 3.7V output and supports both 510 and eGo-threaded atomisers.
Different EVOD batteries provide slightly different capacities and levels of adjustment, making it worth checking the individual model rather than assuming every version works identically.
Our range can include:
The larger the stated capacity, the more electrical charge the battery can store, although actual runtime will always depend on how frequently the device is used and the resistance of the attached coil.
One of the main differences you'll encounter when comparing traditional pen batteries is whether the output is fixed or variable.
A fixed-output vape battery supplies power at a predetermined voltage.
There isn't normally anything to configure. Attach a suitable tank, switch the battery on and use the firing button when required.
This makes fixed-voltage batteries particularly straightforward for people who simply want their existing tank to work without making regular adjustments.
A variable-voltage vape battery lets you alter the voltage supplied to the attached coil.
Changing the voltage changes the electrical power reaching the coil. Within the coil's suitable operating range, this can alter vapour temperature, vapour production and flavour intensity.
Variable voltage adds a degree of adjustment while retaining the slim shape and relatively simple controls of a pen-style battery.
The KangerTech EVOD VV batteries currently listed in this category are available in both 1000mAh and 1600mAh capacities.
Battery capacity is normally shown in mAh, or milliamp hours.
You can think of this as an indication of how much electrical charge the battery can store. A 1600mAh battery stores more charge than a 650mAh battery, all else being equal.
That doesn't mean you can convert the number directly into an exact number of hours of use, though.
Runtime is affected by several factors, including:
The capacity figure is therefore most useful when comparing similar batteries rather than trying to predict an exact runtime.
Our current range demonstrates how significantly capacity can differ even among batteries with broadly similar designs.
A larger battery can be useful if charging frequency is a priority, while a smaller model may make more sense if keeping the overall device compact matters more.
Compatibility is one of the most important things to check when purchasing a replacement vape battery.
Traditional pen-style hardware commonly uses 510 threading, eGo threading, or a combination of the two.
The KangerTech EVOD 1000mAh battery, for example, is designed to work with compatible 510 and eGo-threaded atomisers.
510 threading became a widely used connection for tanks and other vaping hardware.
A compatible tank screws directly into the battery's connector, creating the electrical connection needed to power the coil.
eGo threading is associated particularly strongly with earlier generations of pen-style hardware and clearomisers.
Some batteries incorporate connections that allow them to work with both compatible eGo and 510 hardware, which can be useful if you're maintaining an older setup.
Always check the connector listed on both the battery and your existing tank before ordering.
Pen batteries are generally best matched with lower-powered tanks and clearomisers designed for relatively modest power requirements.
Traditional EVOD-style tanks and similar mouth-to-lung clearomisers are typical examples.
Compatibility depends on more than whether the threads physically fit. You should also consider the electrical requirements of the coil.
Before pairing a tank with a battery, check:
A tank designed for modern high-powered sub-ohm vaping is unlikely to be suitable for a traditional EVOD-style pen battery.
Both devices perform the same basic job – supplying power to an attached tank – but they're designed around quite different priorities.
Neither design is automatically better.
A box mod offers greater power and adjustment, but that can be unnecessary for someone using a straightforward low-powered clearomiser. In that situation, a compact pen battery can make considerably more sense.
It's also important to distinguish between a pen-style battery and a complete vape pen kit.
A battery on this category page generally represents only the power section of the device.
If you're building a device from individual components, you'll therefore need to make sure you already have a compatible tank or purchase one separately.
Modern vape devices have become increasingly feature-heavy, but there are plenty of situations where simpler hardware is actually preferable.
A pen battery can make sense if:
They can also be particularly useful for keeping older vaping hardware operational when a complete replacement kit isn't necessary.
There are a few specifications worth checking before you buy.
Compare the stated mAh rating.
Higher capacity generally means more stored charge, although it often results in a physically longer or larger battery.
Check whether your tank requires a 510 connection, eGo connection or another fitting.
Never assume compatibility simply because two products appear to have similar threading.
If you want the simplest possible operation, fixed output may be preferable.
If your compatible tank benefits from some power adjustment, a variable-voltage battery gives you more control without moving to a full box mod.
Check the supported resistance range of the battery against the coil fitted inside your tank.
Older pen batteries were generally designed around higher-resistance, lower-powered coils and should not automatically be paired with modern sub-ohm hardware.
Battery capacity often affects device length.
A 650mAh EVOD-style battery can create a noticeably smaller setup than a larger 1600mAh version, so portability and capacity need to be balanced against one another.
Their simple controls can make pen-style batteries relatively easy to understand compared with highly adjustable vape mods.
There are normally fewer settings to manage, particularly with fixed-voltage models.
However, buying a standalone battery still requires you to understand tank compatibility. If you're completely new to vaping hardware, a complete vape kit may be easier because its battery and tank have already been designed to work together.
Standalone pen batteries make most sense when you already know which compatible tank or clearomiser you intend to use.
Pen-style batteries remain especially useful as replacement vape batteries.
If the battery in an older EVOD-style setup no longer holds charge effectively, replacing the battery section can allow you to continue using the tank and coils you already own.
When replacing an older battery, compare the original specification carefully.
Check:
If the original model has been discontinued, don't assume another pen battery is a direct replacement without checking these points first.
Charging arrangements vary between models, particularly with older vape hardware.
Some pen batteries use dedicated chargers that connect to the threaded end of the battery, while other designs may use a charging port built directly into the device.
Always use a charger suitable for the specific battery.
Don't assume that a charger is compatible simply because it physically connects. Voltage and charging requirements can differ between devices.
Rechargeable batteries should always be used and charged carefully.
General precautions include:
If you're looking for a straightforward replacement power unit for a compatible vape pen or clearomiser, our pen style battery range keeps things refreshingly simple.
The current collection includes several KangerTech EVOD batteries, with capacities from 650mAh through to 1600mAh and a choice between fixed-output and variable-voltage designs.
Choose the capacity and output style that suits your setup, check compatibility with your existing tank, and you've got an uncomplicated way to keep traditional pen-style vaping hardware in service.
