18650 Battery Charger Guide

Although they have several uses, a 18650 battery charger is generally used for vaping and cameras. Because the market is buzzing right now, there are lots of people bringing out sub-par products and the same can be said for battery chargers.

Fortunately, there are more than enough good ones to choose from but you need to know what to look for. Everything from charge time to battery life is discussed so to make sure you are never caught short, waiting on a low-quality charger to work, here is our 18650 battery charger guide.

What To Look For In a 18650 Battery Charger

Charge Time

This has to be high on your list of priorities as the last thing you want is a slow charger that prevents you from vaping when you want to. Some are crazy fast, taking a matter of minutes to reach full charge whilst others take a bit longer. anything under a few hours is reasonable but if you find something around the two-hour mark for a good price then this isn’t a terrible thing.

Chargers in this range mostly have a rating of 0.5V or 1.0V which is sufficient to give you a speedy charge.

No Overcharging

A lot of 18650 battery chargers will cut off instead of overcharging which will save you money on your bills so look out for those and this prevents the unit from overheating as well.

LED Display

Not all 18650 battery chargers will do this and it’s not as essential as other functions but it is always good to know how full the battery charge is. Some will tell you how much longer the batteries need before they are charged to the max whilst others will show how much each battery is charged.

Car Adapters

This isn’t something you often get so it shouldn’t be something you expect from every brand but the ability to charge on the go is always a good idea. Not only does this save money on electric bills, but it means you will always be able to vape between leaving your car and going into work.


The more reputable brands will offer this and although it isn’t exactly rare, it’s not something you get from every 18650 Battery Charger. A warranty protects your purchase and when it comes to battery chargers, it is always good to know you are going to get a guaranteed amount of use.

Four Slot Battery Chargers

Although 2 slot chargers are enough for most people, there is sometimes a misconception that a 4 slot charger doesn’t work as fast. this isn’t true as it is all down to the power of the individual product. A quality 4-slot charger will charge batteries just as fast, it doesn’t matter if there are two or four on the go at the same time.


Because they are compact, 18650 battery chargers fit easily in the bottom of a bag so if you are away on business, you don’t have to worry about carrying extra batteries or running out of charge.

Battery Life

Depending on the brand, you can get 1,000’s of hours of battery life out of a rechargeable 18650 battery. This is one of the main benefits of being able to use such a product so make sure it is capable of lasting as long as the batteries.

Other Benefits From A 18650 Battery Charger

Multiple Battery Chargers

As their name suggests, these types of products can charge different types of batteries at the same time. This is great and it stops you from having to buy multiple chargers and is often compatible with batteries such as Li-on, IMR, Ni-Cd, and others.

More Life For Old Batteries

When batteries have been left idle for some time, they are often considered ‘dead’ and beyond repair. This isn’t always the case. A strong 18650 battery charger will be able to give old batteries a kick start to make them useable again. Some 18650 battery chargers have this ability built-in as a function that makes them stand out from the competition.

Why Is It Important To Buy A Quality 18650 Battery Charger?

Because there are fake products on the market, you must get your hands on a genuine, high-quality product. Otherwise, you could find yourself buying a product that reduces the longevity of the battery, causing lasting damage. Find a reputable brand, use the charger correctly, and you shouldn’t have any issues.
