Most vapers who use mods have an interest in finding the best 18650 battery charger. Some mods come with in-built batteries, but many require separately-purchased batteries an offer more flexibility and longevity as a result. But not all vape charger units are created equally. Not only can the prices vary, the charging speed and the reliability of the chargers can differ substantially.
Finding the best vape battery charger means considering various factors including safety, accuracy and how many batteries it can support. Most chargers do the job well enough for most purposes, but if you want the best charger for 18650 battery mods, here are our picks.
Best 4-Bay 18650 Battery Chargers for Vaping
We’ve split this list of the best 18650 battery charger options into two groups, one for 2-bay chargers and one for 4-bay chargers. Here are five of the best 4-bay battery chargers for vaping if you have multiple vape devices and want to minimize your charging time.
5 – Nitecore D4
Nitecore is a huge name in chargers, and many of the best 18650 battery chargers in this list are made by them. The e-cig battery charger has four independent charging bays, so you can charge multiple batteries (even of different types) simultaneously. When you insert a battery, the charger automatically detects the type of battery you have installed (apart from LiFePO4, which you have to select) and switches to the most appropriate charging mode. It supports most sizes of Li-ion battery – 26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500 and 10440 – as well as Ni-MH, IMR, LiFePO4 and NiCd options.
The 18650 battery charger has an LCD display so you can see the charging status of each battery you have installed, and if any have finished charging. The charging speed isn’t as high as some of the options on this best vape battery charger list, at 375 mA (i.e. 0.375 A) for four batteries simultaneously charging and 750 mA (0.75 A) for two batteries. It does have all the expected safety features, though, with reverse polarity, overheating protection, and over-charge protection.
This device is in the running for the title of best charger for 18650 battery mods thanks to its fast-charging, nice design and affordable price. The Q4 has a simple, no-button design, and has four independent battery bays which you can use to charge a wide variety of vaping batteries. These include 18500, 18650, 22650 and 26650, as well as many other sizes, both Li-ion and LiMn. The display is relatively simple – with each just informing you if the slot is charging – but this makes it easy to get the key information at-a-glance.
If you’re charging three or four batteries, the Lush Q4 operates at 0.5 A, with 1 A charging for two batteries and 2 A charging for a single battery. These settings are automatic, though, so you can’t choose to charge at a slower rate without charging more batteries simultaneously. It automatically stops charging when your battery reaches 4.2 V, and has reverse polarity, over-voltage and short-circuit protection.
The VP4 from Xtar is a reputable charger with four independent bays that works with a huge range of lithium ion batteries. As well as being one of the top-rated 18650 battery charger units, it also supports 18350, 18500, 22650, 26650 and many other sizes of battery (although others aren’t commonly used for vaping). This means you can use it as a vape battery charger for any size of battery you’ll come across when you’re vaping.
It has an LCD display screen which shows information for the charging status of each battery you have loaded up. It can charge four batteries simultaneously at 0.25 or 0.5 A, or two batteries at 1 A, with the outer bays offering faster charging. There is a precision cut-off to ensure your batteries aren’t charged to over 4.2 V, it can wake up “sleeping” or over-discharged batteries, and has plenty of safety features like reverse polarity and short circuit protection. Some other units on this list have more features, but the VP4 offers everything you’ll need for most purposes.
Efest’s LUC V4 is a fairly basic-looking but still effective entrant on to this list, with four independent bays and support for most Li-ion and LiMn batteries. As well as 18650 batteries, it also supports 10440, 14500, 14650, 18500, 17670, 18700, 26500 and 26650 battery sizes. The charger is also features a USB charging port, which isn’t especially important but is a nice extra for charging your smartphone or other devices. It has a display that shows each battery’s charge level, and can charge at 0.5, 1 or 2 A (with the fastest speed only available when charging two 26650 or 25550 batteries).
This Efest 18650 charger has protections against overcharging, short circuits and reverse polarity, and it can be used to revive any batteries still at 0.6 V or higher. The vape charger offers pretty much everything you need from an 18650 charger, and you can pick it up for $29.95.
1 – Nitecore i4 Intellicharger
The i4 Intellicharger from Nitecore strikes a great balance between low price and excellent performance, and this earns it our pick as the best vape battery charger in the category. The unit has four independenly-controlled bays, and it automatically detects the battery you have installed and chooses the most appropriate charging method. It’s compatible with all of the battery sizes you could need for vaping – including 18350, 18490, 18650, 22650 and 26650 – and many more, and supports Li-ion, IMR, LiFePO4, NiCd and Ni-MH batteries.
The e-cig battery charger works at different speeds depending on how many batteries you’re charging simultaneously. For four batteries, it runs at 375 mA (0.375 A), for two it runs at 750 mA (0.75 A) and for a single battery it works at up to 1.5 A. There are three LED indicators to show the charge level of the battery in each slot. As you’d expect, it also features overcharge, short circuit and reverse polarity protection, as well as a feature to prevent charging for excessive amounts of time (cutting off at 20 hours).
You can pick up the best 18650 battery charger in the class for just $19.99.
Best 2-Bay Vape Battery Chargers
If you aren’t likely to need to charge four batteries simultaneously, the best 2-bay battery chargers for vaping will give you more than enough options for charging your batteries.
5 – Efest Pro C2
The Efest Pro C2 takes fifth spot in the best 18650 battery charger for 2 bay devices thanks to its versatility and low price. It supports sizes from 10440 to 26650 – of course including 18650s – and offers charging at up to 1 A. It has a simple two-bay design, with LED indicator lights above each bay so you can keep track of how each of the cells is doing. It’s completely independent, so even if you start with two batteries at different charge levels, you’ll be informed when each is completed individually. The charger has a non-slip backing, so you can rest assured that the charger will stay in place on pretty much any surface.
The Pro C2 is also a smart charger, so it stops applying current when the battery has fully recharged. It also has all the expected safety features, including reverse polarity protection, over-charge and short-circuit protection. Efest has also incorporated venting on the back to protect against the unlikely event of overheating, as well as general fire resistance. The charger comes with a wall adapter, warranty card and instruction manual as standard.
The Lush Q2 is the smaller version of the Q4 from Efest. While the features are essentially the same as on the larger unit, it still deserves a mention on this list of the best vape battery chargers for vapers who can get by with two independent battery bays. Like the larger version, it has displays for each battery bay, but doesn’t give any indication of charge level until your battery is fully-charged. It supports 18500, 18650, 22650 and 26650 vaping batteries, along with many others you’re unlikely to come across in a mod. It supports Li-ion and LiMn chemistries.
The Lush Q2 charges single batteries at 2 A and reduces this to 1 A when you have two batteries inserted. This is an impressive charge speed for two batteries, and is one of the reasons it earns a spot among the best vape battery charger devices. However, like the Q4, this is automatically selected. It features over-charging, reverse polarity and short circuit protection, and can recover batteries with over 0.6 V left in them.
The i2 Intelligent charger from Nitecore is a scaled-down version of the i4, with just two independent bays but all the same features that earned the larger device a spot on this best vape battery charger list. The i2 works with Li-ion, IMR, Ni-MH, NiCd and LiFePO4 chemistries, and covers a wide range of sizes. For an e-cig battery charger, the most important sizes covered are 18350, 18490, 18650 and 26650, but many others work with the i2 as well.
When you’re charging two batteries simultaneously, the i2 Intelligent charger works at 0.5 A, but this increases to 1 A when you’re only charging a single cell. There are LED lights to give a rough display of your current charge level, with marks for 30%, 80% and 100% charged, and a red LED to show a slot charging at 1 A. It can revive low voltage batteries, and has over charge, over time, short circuit and reverse polarity protection.
The VC2 Plus from Xtar makes this list thanks to its wide compatibility, affordable price and impressive range of features. It has two independent bays for batteries, and also features a USB output port, allowing it to charge other devices along with vaping batteries. The VC2 plus also works as a power bank, which is a really handy extra feature. Like many of the top vape battery chargers, it automatically recognizes the type of battery you’ve inserted and adjusts its behavior accordingly. It supports pretty much any battery you’ll use for vaping, including 18350, 18490, 18500, 18650, 22650 and 26650, as well as many others including huge 32650 options. It can be used with Li-ion, IMR, INR, NiMH and NiCd batteries.
One of the features that puts the VC2 Plus in the running for the title of best charger for 18650 battery using vapers is the option of controlling charge speed. It either works at 0.5 or 1 A, which is great for vapers looking for a quick charge on multiple batteries simultaneously. It also has a countdown timer when you’re charging – as well as an accurate display of the current charge level – so you know exactly how long it will take. It can revive low-voltage batteries, and it has short circuit, over-charging and reverse polarity protection. Unlike most options, this is actually an 18650 USB charger, which is powered by any standard USB port or wall adapter.
The Q2 from Nitecore earns the title of best 18650 battery charger for its fast charging, huge range of compatible batteries and nice design. It supports essentially any size of vaping battery, including 18350, 18490, 18650, 20700, 21700 and 26650, as well as many others. Aside from the eye-catching color options, it looks pretty much like any other vaping battery charger: two bays arranged side-by-side with LED indicator lights above each one. The charger monitors each bay independently, and stops charging automatically when the battery occupying a bay reaches 4.2 V.
The current output from the charger depends on how many batteries you’re working with, operating at 2 A when you have a single cell and 1 A in each when you have two. You can also choose to work in constant current or constant voltage charging mode, although the charger automatically switches based on the power level of the battery (so you don’t really have to do anything). Of course it includes all the usual protections, including overcharging, reverse polarity and short circuit protection. It’s also designed with heat dissipation in mind and is made from durable, fire-resistant material.
You can pick up the charger (along with wall adapter) for $18.91.
18650 Battery Charger Basics
The lists above offer all of the basic information on your options when you’re looking for the best charger for 18650 battery mods, but you might not be sure of the basics of how you should charge your batteries, how to charge safely, or what type of thing you should look out for when you’re making your decision. This section will give you a run-down of the main things you need to know.
A Charging Guide for Vapers: How to Charge Your Batteries
If you’re wondering how to charge 18650 battery mods, the answer is thankfully pretty simple. Vaping batteries are really just like any other battery – they have a positive end (which has a protruding button section) and a negative end (which is completely flat). The positive end usually has an indented ring around the tube of the battery too so this is generally easy to identify.
To charge, remove the battery from your mod. You don’t access the battery section in the same way on every mod, but generally speaking there will either be a cap to unscrew to get access or a panel you can remove. When you remove the battery, identify the positive and negative ends.
Battery chargers are usually explicitly labeled with a “+” and a “−” sign for the positive and negative ends. You simply insert your battery in the correct polarity. Don’t worry if you get it wrong, though, good chargers – like all of those in our 18650 vape battery charger lists above – throw up an error message if you insert it the wrong way around.
Then plug in and switch on your vape battery charger. In most cases, this is all you need to do. The charger identifies that you have a battery inserted, and sets itself in the appropriate mode for what you have inserted. You won’t encounter vaping batteries with unusual chemistries, so there is rarely any need to press anything. For example, if you had an LiFePO4 battery, you’d need to press a button on a Nitecore battery charger to put it in the correct charging mode. But vaping batteries are basically all Li-ion, IMR or INR, so you won’t need to do this.
This is really all you need to know when it comes to how to charge a vape battery. Good chargers (like all of those listed above) will at least stop charging and give you an indication when the battery is fully charged, and most will give you a continuous indication of the charge level. Simply wait for it to be fully charged and when you notice it’s done, remove the battery or batteries and re-insert into your mod.
Vape Safety Guide for Charging a Battery
As long as you buy one of the high-quality options from our list of battery charger units, you’re unlikely to run into safety issues when you recharge. However, it’s still a good idea to know the basics of battery charging safety. So here’s a brief bullet-point vape safety guide for charging a battery:
Make sure your charger has over-charge protection. Over-charging your batteries regularly will impact its lifespan and could lead to more serious issues as a result of the stress on the internal components. The best advice is to get a battery with over-charge protection. Even if you do, though, it’s still worth removing your batteries from charge as soon as you notice they’re done.
Don’t leave your batteries charging unattended. You’re unlikely to run into issues with a high quality vape battery charger, but it’s still good advice to not leave your batteries charging unattended. It’s also better to not leave them charging overnight.
Charge away from heat sources or flammable materials. Overheating can cause issues with lithium-ion batteries, so it’s best to avoid charging near heat sources or in direct sunlight. Keep your charger away from flammable materials too, just in case there is a problem.
Check how quickly your battery can charge. Batteries ideally shouldn’t be charged at higher than 0.8C, where 1 C is the capacity of the battery. So if you have a 2,000 mAh capacity battery, it shouldn’t be charged at a higher current than 1.6 A. Find out your battery’s capacity and multiply it by 0.8 to find this number (in the example above, 2,000 mAh ×8 C = 1,600 mA = 1.6 A). Technically, lower-speed charging is better for maintaining battery life, so really it’s better to charge at 0.5 C. In this case, multiply the capacity by 0.5 to find the safe charging current. In the example above, this would be 2,000 mAh × 0.5 C = 1,000 mA = 1 A.
For in-built battery devices, use the recommended charger. If you have a vape pen, hookah pen, internal battery mod or a cigalike, using the charger that came with your device is the best way to stay safe. The hookah pen charger you get with your device will definitely be safe, so just stick with it. Although you can match the output on your original charger with the output on your new charger, it’s easier to just use the manufacturer’s charger if possible.
Don’t buy cheap chargers. Battery chargers don’t seem important, but they really are. Don’t just choose the cheapest charger you can find. Stick with reliable manufacturers and choose one of the e-cig charger options listed in the lists above to stay safe.
Choosing Your Vape Battery Charger
As long as you stick with a reliable manufacturer and recommended vape battery chargers, you’re unlikely to run into issues when charging your batteries. However, you do have to choose a specific charger somehow, so here are some general tips for getting the right one for your needs.
2 bays or 4 bays? Although it might seem like getting a charger with more bays is automatically better, if you only have a couple of vape mods, you might be able to save a bit of money by getting a smaller but still high-quality charger. However, if you have several batteries and are likely to get more, 4-bay battery chargers (or even bigger ones) don’t cost too much more.
How quickly does it charge, and does it let you choose charging speed? Provided your batteries can take the higher current safely (see the previous section for details), the top 18650 battery chargers can generally charge at a higher current. Charging more slowly is generally safer anyway, but if you’re likely to be in a rush getting a faster charger is generally better. The best vape battery charger devices give you a choice of how fast to charge.
What are the safety features? The best vape battery charger devices have a range of safety features too. The most important is over-charge protection, but short circuit protection and reverse polarity protection are important too. There should also be some venting for the heat generated by charging.
What is it compatible with? Although every entry on the lists above class as 18650 battery chargers, you may have other sizes of battery too. Check which batteries are compatible with your charger prior to making your purchase.
Check an 18650 battery charger review before buying. Looking at specs and features gives you a broad idea of what a charger can do, but there is no substitute for checking an 18650 battery charger review for the device you’re considering prior to buying.
Conclusion: Don’t Sacrifice Quality for Price
Getting a high-quality, safe battery and a high-quality vape battery charger is essential if you’re going to stay safe when you vape. Our best 18650 battery charger lists are a great guide, but if you decide to pick something up not listed above, make sure it’s high-quality and not just something you’re picking up because it’s cheap. Safety should be paramount when making your choice. Don’t worry too much, but remember that it’s not worth cutting corners when it comes to chargers.
