Buying Guide For The Best 21700 Battery Charger

1. Compatibility

Before you buy any battery charger, it’s crucial to know if it will work with your current setup (or future setups). Samsung’s ICR21750s are extremely popular at the moment since they’ve taken over much of the vape world in terms of popularity, but you’ll need something like Nitecore D4s Digital Intelligent Charger when it comes time to charge them.

If you have multiple devices, your charger will need to accommodate all of them. You could have a variety of different brands, sizes and batteries because you own mods, e-cigs, vape pens and more! If this is the case, it’s probably best you go with one of the many multi-chargers on the market that are made for vapers by vapers.

2. Portability

One thing about vaping that makes charging special is that there are usually no designated outlets available to use in public places like libraries or schools (and most cafes don’t allow them either). This means when you’re traveling or enjoying yourself at an event, your only option is often to take care of business in your car or in a public restroom.

One of the best things about more technologically advanced batteries is that they don’t take forever to charge up! That said, it’s also important to get a charger that isn’t too bulky. It’ll be very difficult if you want to take care of your batteries on-the-go and one of the most common complaints you hear from vapers is that their chargers are just way too big for everything else they need in their bags or cars. Something like Tiny TC200 Smart USB Battery Charger is ideal because of its small size and portability while still offering maximum power.

3. Port compatibility

Speaking of something being too big, another thing to consider is the ports! Most 21700 battery chargers use Micro USB or USB-C inputs, but these ports work very differently from device to device. If you need a charger that’s compatible with all types of phones and other devices (including Macs) then you’ll probably want one that has either both or neither.

4. Safety features

Something else to look out for is safety features! Even though we’re talking about batteries here, it’s important for whatever you get to be safe and reliable. First and foremost, make sure the battery slots are properly spaced—your batteries should never touch each other while they’re charging because this can lead to overheating and even fires! Furthermore, if your chargers doesn’t tell you when your batteries are fully charged (or it takes too long to do so), consider one that does.

5. Charging speed

Finally, find one that’s not only reliable but also fast! You probably know by now that charging time varies between mAhs and the overall quality of the battery itself. Of course, some chargers are faster than others because of their ports, chipsets and more. If you’re buying a 21700 battery charger for vaping purposes then it’s probably best to go with something that won’t take all day to power up your cells. Some of these come standard with power banks too, so if you want to charge your phone while you do other things on-the-go like driving for example consider getting one of those too.
