The Definition of Power Banks

How Do Power Banks Work?

The way that power banks work is also simple, as manufacturers have made them user-friendly for beginner and advanced mobile users. All you have to do is plug the power bank into a device so that it can charge it, and then disconnect it once it has a full battery.

While you’re out and about and you notice your phone is low on battery, connect it to the power bank using your charging cable. At this point, the power bank should automatically start charging your mobile.

Some power banks have more advanced features, depending on their quality and their cost. The higher-end models may have buttons to allow you to switch from port to port or come equipped with an onboard emergency LED light. You may also notice that some power banks have LCD screens that give you real-time information about battery levels and charging times.

Where Can I Find a Power Bank?

Once you’ve answered what is a power bank for mobile, and you’ve decided that you’d like one, you can find them anywhere. Big box stores, electronics stores, and online stores are your best bet.

It’s important to remember to do some brief research to make sure you’re choosing the right power bank for your needs, though. The most important things to look out for include:

Charging Capacity

Any charging capacity between 10,000mAh and 25,000mAh is ideal for smartphones, tablets, and small electronics. On average, you should be able to get up to seven full charges with a 22,000mAh power bank.


As this is something that you will be traveling with, your chosen power bank should be durable. You’ll want a safe casing that will protect the internal components from damage if you accidentally drop the unit.

It’s also important to find a casing that withstands scratches, dents, and even fingerprints so that it always looks brand new.

Multiple Charging Ports

The lowest number of charging ports that your power bank should have is two. Two ports enable you to charge two devices at the same time, so all of your devices will always be ready to use.

Smart Charging

Smart or intelligent charging is a feature that is highly recommended because it protects your connected devices. Not only does this technology optimize the charging outputs, but it also protects your mobile from overcharging, experiencing changes in voltage, and over-discharging.

No matter if you’re hours away from an outlet or you’re stuck on a plane, a power bank gives you the ability to keep your device at a healthy battery level. You’ll never have to worry about having a dead phone again, especially in emergencies.

Important cons of owning a power bank include:

USB Charging

If you want peace of mind to protect you in an emergency or the ability to use your GPS even with a dying phone, these units are useful.
