What Are Vape Batteries and Chargers?

Vape batteries and chargers are the accessories that keep your vaping device powered safely and consistently. In this collection, "batteries" covers two related but different product types.

The first is an external smart charger, a standalone unit you plug into the mains or a USB port to charge removable cells such as 18650, 21700, 20700 or 18350 batteries. These are the cells used inside many vape mods and box mods, and they're taken out of the device to be charged separately.

The second is a built-in rechargeable pod battery, like the SKE Crystal Plus, which is charged directly through its own Type-C port while the battery stays inside the device. You don't remove a cell from this type of product; the whole unit is the battery.

Understanding which type your device needs matters, because external chargers and standalone pod batteries are not interchangeable. Always check your device's manual or product listing before buying a replacement.

How to Use Vape Batteries and Chargers Safely

Using your vape batteries and chargers correctly helps maximise battery life and ensures safe, reliable performance. Always use a compatible charger for your battery type, insert the batteries in the correct direction, and avoid leaving them charging unattended.

Remove the batteries once fully charged, store them in a protective battery case when not in use, and replace any battery that shows signs of damage or excessive wear.

Following these simple steps will help keep your vape device performing at its best while reducing safety risks. 

Using an external charger

Insert your 18650, 21700, or compatible cell into the charging bay, matching the positive and negative terminals as marked on the charger. Most models in this collection, including the Nitecore Intellicharger and Ci2, automatically detect the battery type and select an appropriate charge current, so there's no need to set anything manually on those units.

Plug the charger into a USB port or mains adapter and check the indicator light. Most chargers show a red or amber light while charging and switch to green when the cell is fully charged. Never leave a charger unattended for extended periods, and always remove batteries once charging is complete.

Using a rechargeable pod battery

Connect the Type-C cable directly to the device and to a USB power source. There's no cell to remove; the battery charges in place. Once full, disconnect the cable and continue using the device as normal with a compatible prefilled pod.

Efest

Efest produces dependable dual-slot chargers built around independent bay monitoring, so two cells can charge at their own pace without one affecting the other. The Efest Soda and Efest K2 Slim are both stocked here. The Soda suits vapers running dual-battery mods, while the slimmer K2 is a compact everyday option for single-cell devices.

The Efest Soda and Efest K2 Slim are both stocked here, giving buyers a straightforward choice between a dual-slot and a slim single-format design.

Golisi

Golisi specialises in compact, no-fuss chargers built for vapers who want reliable USB charging without unnecessary complexity. Their designs prioritise portability, both the Golisi L2 USB Mini Charger and the Golisi Needle 4 Compact Battery Charger fit easily into a bag, drawer, or travel kit.

Nitecore

Nitecore has built a reputation in battery technology that extends well beyond the vaping industry, and that engineering pedigree is evident in every charger they produce. The Nitecore Ci2 Dual Slot and Nitecore Intellicharger NEW i2 Charger both feature automatic current detection, meaning the charger identifies your cell type and selects the appropriate charge rate without any manual input.

For vapers running high-drain 18650 or 21700 cells in mods, Nitecore is one of the most trusted names in safe, controlled charging. 

SKE

SKE is best known for the Crystal Bar range, one of the UK's most recognised disposable-style vape lines, and the SKE Crystal Plus Battery extends that familiarity into a dedicated rechargeable pod device. Unlike the external chargers in this collection, the Crystal Plus charges directly through its own USB-C port, no removable cells, no separate charger needed. It's designed specifically for MTL-style vaping with SKE's prefilled pods, making it a natural next step for existing Crystal Bar users moving to a reusable system.

Types of Batteries Available

This collection splits into two clear categories rather than nicotine strength or flavour variants, since batteries and chargers are hardware rather than consumables.

Dual-Slot External Chargers

Charge two removable batteries at the same time, making them ideal for vapers who use dual-battery devices or keep spare cells ready to swap. These chargers offer efficient charging and convenient battery management.

Compact Single-Slot & Slim External Chargers

Perfect for charging one battery at a time, these compact chargers are a great choice for everyday use. Their lightweight design makes them easy to carry and store without taking up much space.

Standalone Rechargeable Pod Batteries

Built with an integrated rechargeable battery, these devices are designed to work with compatible prefilled pod systems. They provide a simple, convenient vaping experience without the need for separate external batteries.

Always match the charger to the cell size stated in your mod's manual, and never mix cells of different capacities or ages in a dual-slot charger.

FAQs

Do I need a special charger for my vape battery?

Yes. External cells such as 18650 or 21700 need a dedicated smart charger like those from Efest, Golisi or Nitecore. Devices with a built-in battery, such as the SKE Crystal Plus, charge through their own cable instead and don't use these external chargers.

How long does it take to charge a vape battery? 

Charging time varies depending on the charger's output current and the battery's capacity. As a general guide, a 3000mAh 18650 cell typically takes 3–5 hours on a standard 1A charger and around 1.5–2 hours on a 2A fast-charge unit.

Always check the individual product listing for model-specific charge times, and avoid leaving batteries on charge longer than necessary.

Can I charge two different batteries together in a dual-slot charger?

Most dual-slot chargers in this collection, including the Efest Soda and Nitecore Ci2, monitor each slot independently. Even so, it's good practice to charge cells of the same capacity and age together where possible, and to follow the manufacturer's instructions.

What's the difference between the SKE Crystal Plus and the external chargers?

The SKE Crystal Plus is a complete rechargeable device battery designed to pair with SKE prefilled pods, charged via its own Type-C port. The external chargers are separate accessories used to charge removable cells that sit inside a different type of device, such as a mod.

How do I know which cell size my mod needs?

Check your mod's manual, box, or product listing, it will clearly state the compatible cell size, such as 18650 or 21700. If you're unsure, our product pages list compatible cell sizes for every charger stocked. When in doubt, contact our customer support team before ordering.

What is the difference between 18650 and 21700 vape batteries? 

The 18650 and 21700 refer to the physical dimensions of the cell. 18650 measures 18mm × 65mm, while the 21700 is slightly larger at 21mm × 70mm.

The 21700 generally offers higher capacity and longer battery life between charges, making it a popular choice in newer, high-powered mods. As the two sizes are not interchangeable, always check which format your device supports before purchasing.

Is it safe to leave a battery charger plugged in overnight?

We'd always recommend following the manufacturer's guidance and staying nearby while charging where practical, rather than leaving units unattended for long periods. Most chargers stocked here include automatic cut-off once a cell reaches full charge.

Are the batteries and chargers at Vape Wave genuine and UK-compliant?

Yes. Every battery and charger listed in this collection is genuine stock sourced from authorised suppliers. Brands including Efest, Golisi, Nitecore and SKE are all established manufacturers with verified UK availability. The 18+ requirement and all relevant UK trading standards apply across the Vape Wave store.

Where should I store spare vape batteries?

Store removable cells in a cool, dry place away from direct sunlight and metal objects, ideally in a battery case, to reduce the risk of accidental contact between terminals.

Can I use any charger with any 18650 battery?

Most modern smart chargers, including the models here, are built to accept standard 18650, 21700, 20700 and similar sizes, but always check the specific charger's compatible cell range on its product page before buying.

Do these chargers come with a UK plug?

Product listings specify the exact cable and plug configuration included, so check the individual page for full details before ordering.

What age do I need to be to buy from this collection?

Vape Wave sells to UK customers aged 18 and over only, in line with UK vaping regulations. Age verification checks may apply at checkout or on delivery.
