6 Best Vape Chargers In 2024

As the best battery charger, the Nitecore Intellicharger I8 does it all. A quick look at the casing reveals an industrial design that keeps the carry weight down even at a larger scale. The ‘threaded’ plastic design also provides even heat distribution, essential when charging several cells simultaneously.

As its name suggests, the I8 can charge up to 8 batteries simultaneously and is compatible with almost any rechargeable battery used for vaping, including 18650, 20700, 21700, and many more.

It also has a simple red/green LED indicator to inform you when your batteries have finished charging, making this technical masterpiece surprisingly easy for beginners. 

Coverall: Sturdy, fire-resistant battery cover 
LED FTW: Easy-to-read LED screen 
Bank It: Can also be used as a portable device charger 

Of course, there are many options between 8-bay and single-bay chargers, such as the dual-bay XTAR PB2S Charger. This neat and attractive little box helps to keep two vape batteries evenly charged and protected in transit.

The PB2S is unlike other battery chargers featured in this list because it has a removable bay shield to protect batteries. The charger also uses intelligent power increments to not overload a depleted cell too quickly.

What’s more, the PB2S can even be a portable battery bank, and even a USB charger for other electronic devices such as phones, controllers and portable speakers.

21 Fun: Ideal for recharging 21700 batteries 
Lazarus: IMR battery recovery feature to bring dead batteries back 
Keep It Level: Precise charging current distribution technology

21700 batteries are the second most popular external battery cell used in vape mods, and the Nitecore i4 Intellicharger is well suited to the task of charging them, along with many other battery types.

You can charge anything between 1 and 4 batteries at once, each with different charge requirements if you need to! The device has been built with special heat-distribution technology to ensure that it won’t overheat during intensive recharging sessions.

And best of all, the I4 charger can be used to resurrect many depleted batteries, saving you the cost of having to purchase a new unit! 

18650 FTW: Perfect for charging 18650 batteries 
Speedy: Quick 2A charge speeds
Individual: LED indicators for all four battery bays

18650 batteries are the most commonly used in external battery vape mods, and the Nitecore Q4 is ideally suited to charging them evenly and safely.

Despite being a Nitecore device and displaying all the industrial-grade quality they’re known for, the Q4 is remarkably simple. The charger doesn’t feature any confusing readouts or buttons; you just put your vape cells in place and wait for the individual LEDs to change from charging red to charged green!

And it doesn’t limit itself to 18650 cells; you can charge up to four different kinds of battery at once for your vape devices, each of which will receive an appropriate charging mode for long-term battery safety. 

Single Bae: Charge a single battery  
Power Picker: Compatible with 18650, 20700 and 21700 cells 
On The Move: Compact and easy to travel with 

Not every external battery mod requires dual-18650s, and the Efest Slim K1 Charger is a good choice for those looking for single-bay battery chargers to keep one or two batteries topped up.

Built with simplicity in mind, the Efest Slim K1 doesn’t confuse you with weird menus and readouts. Just pop an 18650, 20700 or 21700 in and watch it charge on the charge rate display screen!

While the charge speed isn’t the fastest at 1A, the charger is easy to travel with due to its small and discreet size. But handle it carefully, as the slim build makes it more fragile than others.

Quick Charge: 2.1A charging speeds 
No Press: Buttonless operation 
2-In-1: Charger and power bank 

One downside of external vape battery chargers is that the charging speed can be slower than when charged inside the mod. But that isn’t the case with chargers like the Efest Lush Box Charger, which can achieve lightning-fast 2.1A charge speeds.

The scratch-resistant LED screen displays a simple charge rate readout, so you’ll know when your cells are ready for removal. The battery charger is also entirely buttonless; just put your 18650 rechargeable batteries in and let it rip!

Like the XTAR PB2S, the Lush Box can also be used as a portable USB charging bank, which is great if you need to top off your phone’s battery alongside your vaping cells.
