Factors to Consider when Choosing the Best 18650 Battery Charger

1. Number of charging bays

18650 battery chargers normally come with single, double, triple, quadruple (four), or sextuple (six) charging bays. When it comes to charging bays, your choice rests entirely on the number of batteries you intend on charging at once.

Most people go for two-bay chargers, but if you intend to charge more than two batteries a day, you should choose a four or six-bay charger.

2. Does it have independent charging bays?

Chargers with independent charging bays offer less charge time for each battery charging when compared to regular chargers. This is because independent charging bays don't share a circuit; shared circuits contribute to a longer charging time.

On the downside, chargers with true independent charging bays will set you back a few more dollars since they have more components and offer better convenience.

Also, when buying a charger with independent charging bays, always buy from a trusted brand. This is because most four and six-bay chargers share circuits between two bays, increasing your charging time significantly when charging different batteries.

3. Does it come with LED Lights or an LCD Screen?

18650 battery chargers use LED lights and LCD screens to display crucial information. Budget chargers normally use LED lights, while their more advanced counterparts use LCD screens.

LCD screens offer more convenience as you can monitor the batteries’ charging process and read the battery's voltage effortlessly. That being said, although an LCD screen is an added advantage, it is not really necessary.

On the other hand, if you don’t have a millimeter to test your battery's voltage, it is advisable that you use a charger with an LCD screen.

4. How portable do you need the charger to be?

Although the portability of a 18650 charger isn't essential, you should think about it before making your purchase. If you move around constantly, it’s best to choose one with a minimalistic design. Likewise, it would help if you also considered its docking options.

A charger with a USB power inlet comes in handy when you’re using it in a vehicle or any other place where a wall inlet is not available.

Similarly, if you plan to use your charger in the house or on-site, you should consider getting a charger with a mains plug.

5. How much are you planning to spend?

No matter how many features you want on your charger, the model you take home ultimately depends on your budget.

If you plan on charging one or two batteries a day, then you don't have to all-out to buy a six-bay charger. That being said, when looking for an affordable charger, always buy from a reputable brand since most budget chargers sacrifice quality.

6. Safety

Whenever you go battery charger-shopping, always ensure that the charger has all the relevant safety features installed. As a minimum, a 18650 battery charger should have overcharge, reverse polarity, and thermal protection. All the batteries we’ve reviewed have met and exceeded these minimum safety requirements.

7. Which features do you want the charger to have?

You might think that a charger is just a charger, but there’s a lot more to it than meets the eye. And when it comes to 18650 battery chargers, features determine both their functionality and convenience.

One of the most basic features to look out for in a charger is a display screen. Accelerated charging is also a big plus since it reduces your battery's charging time tremendously without damaging them.

18650 battery charger Frequently Asked Questions (FAQs)

At what current should I charge my 18650 battery?

A battery charger's current rating is one of the most important things to look out for when buying a battery charger. But, since most chargers have adjustable charging currents, we’ll not dive into that right now.

The optimum charging current of a 18650 battery depends on its individual specifications. You should, however, note that the maximum charging current for any 18650 battery should be 0.5% of its capacity.

This means that a 3400mAh battery should be charged with an output current of 1700mAh. Charging with any current above 0.5% of its capacity will lead to overheating, which will ultimately reduce the battery’s life.

However, charging your batteries at a lower current rating will charge the battery safely but at a slower pace.

That being said, it is safe for you to charge your batteries at a slightly higher current rating. But this should only be done very rarely in emergencies since prolonged charging with an excess current will ultimately damage your battery.

What is the best vape 18650 battery charger?

The best battery charger you can get for your vape batteries is one that will meet all your demands and not affect your battery’s life. Such a charger should output the correct voltage, have a protection circuit, and an LCD screen to display all vital charging information.

One of the best brands producing such chargers is Nitecore. Nicole produces some of the best and most versatile chargers on the market.

Also, most of the chargers they produce have a protection circuit and a display screen to display all vital charging information useful for both safety and monitoring purposes.

How can I buy the best 18650 battery charger?

If you want to end up with the best 18650 battery charger, you must know what to look for. We’ve already mentioned most of that stuff above, so I’m not going to get into it.

That being said, if you have a small budget and can’t afford a high-end charger with variable output parameters, you need to pay attention to your batteries’ specifications. Doing that will enable you to purchase a charger that suits your batteries.

It would be best if you also considered the brand and its reputation. Apart from Nitecore, you can also go for ESYB chargers since it’s also a reputable brand.

Also, when buying online, always check the reviews of people who have already purchased the model. Reading the reviews will ensure that you get a clear picture of what to expect.
