Best 18650 Battery Chargers
By Lindsay Fox Posted May 2, 2018
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.
The Nitecore battery charger costs $29.99.
4 – Efest Lush Q4

Best 2-Bay 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 Lush Q2
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.

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.
