The complete guide to picking the Best 18650 Battery Charger 2021

Whether you are using them for vaping or any other purpose, 18650 batteries require a charger that can provide reliable and consistent power. In fact, the quality of the charger has a significant impact on the performance of the batteries. To get the most out of your devices, it is imperative that you opt for the highest quality charger that your budget can allow. In this article, we will go over the main features of these chargers and we will help you pick the best 18650 battery charger that is available on the market today.

18650 Battery Charger Buying Guide

If you are new to the world of vaping, then you are probably not sure what to look for with regard to high-quality accessories. There is nothing to worry about as these devices are fairly simple and identifying their essential features is quite easy. Here is a look at some of the characteristics that every good charger should have.

Quick charging time

This is probably the first factor that you should focus on. A fast charging time offers a lot of conveniences and eliminates the long interruptions that occur every time the battery runs out. The chargers that boast this quality are often equipped with high-end technologies such as iQuick and EBL.

LED indicators

This feature lets you know the charge status of the battery. The LED indicators need to be crystal clear and wide enough to provide easy reading of the data. Outdated chargers that don’t have LED or LCD indicators can lead to overcharging, which could cause irreparable damage to your battery.

Overcharging protection

A charger that is equipped with overcharging protection can get your battery to its maximum voltage without damaging it. This ensures more power efficiency and a longer lifespan. Chargers that don’t come equipped with this feature are likely to damage your batteries within a few months of use.

Extra safety features

Overcharging protection is not the only safety feature that should be included in your charger. Some other critical ones include short-circuiting and overheating protection. To guarantee the longevity of your batteries, opt for a high-quality charger that comes with every single one of these features.

The number of ports

The importance of this factor is predicated on how you intend to use the charger. If you want to charge multiple devices at the same time, then you should opt for an option that comes with more than one port. If that is not the case, a charger with a single bay might be enough for you.
