Power banks are convenient devices that can store a rather large amount of power in order to be used later for charging your smartphones or other devices.

They are the product of the ever-growing need for high capacity power usage that modern communication devices consume, thanks to the many features they incorporate these days.

Cameras, apps, big displays, and WiFi receivers are the main reasons why modern smartphones run out of power very fast. The batteries modern smartphones use are way better than the first batteries used in the old mobile phones, but they’re still not sophisticated enough to give us the enormous amount of power that modern users need.

Of course, there’s always the possibility to make bigger batteries. This means, however, that the phones also have to become bulkier. This is not something many people find attractive, and many manufacturers refrain from even considering.

Thus, it seems that we’ve hit somewhat of a conundrum. Batteries cannot be bigger because of our aesthetic needs, but they also have to have a bigger capacity for all the apps and features we have on our modern smartphones.

Battery power banks are a compromise of sorts, which enables the users to have a separate external battery device that you can take with you and hook your smartphone up on.

This means that power banks are a kind of solution for the problem of ever-growing needs for power supply our powerful devices need.

However, some consider it to be just a temporary solution to the problem. Our needs have simply outrun the possibilities modern batteries are able to offer.

Once we find new ways to make batteries more efficient, the power banks can be the devices that enable us to use our smartphones, tablets and other similar devices according to the needs we have.

How do power banks work?

Think of power banks as separate batteries that are not in your phone, but rather in a completely separate container. This container is usually designed to look like a device on its own.

Most of the modern power banks have exquisite design and can be seen in many arrays of styles, colors and forms.  However, whatever the form or design of the power bank, they all work on the same basic principle.

Just like any other power device, you plug it in the power outlet and charge it. After it reaches it’s maximum capacity, the power bank usually has an integrated feature telling you that the charging is complete. This is usually done by a LED light. (For example, a red LED light indicates that the power bank is empty or close to being empty, while a green light indicates that the power bank is fully charged).

Of course, different power bank models may have different ways of showing you their current charging status and how much power is left in the device, that’s why it is advised to look these indicators up in the manual of the device. Some lusher models might have a percentage number that indicates the current battery status, just like most modern smartphones have.

What to do after it’s fully charged?

After charging your power bank, it is ready to be used for charging your smartphone or any other device it is equipped to charge. Again, you should pay attention to what the manual says which devices are meant to be charged with the particular power bank you have on your hands. We would strongly advice against charging devices the power bank manufacturer has not included in their description.

Usually, devices such as iPhones and Android phones are compatible with most power banks, since they’re the most commonly used phone models today. So, if you have a Windows phone, a BlackBerry or any other device, make sure that the power bank you’re getting is meant to charge that particular phone model.

Once you established that the power bank model you have is compatible with the phone model you have, you may proceed making use of the power bank. The fully charged power bank can, depending on its capacity, charge your phone to the fullest several times.

Other smaller power banks, however, may be designed to only give your phone 50% of its battery life back. So, before buying a power bank, make sure you know what you’re dealing with. If you do that, there will be no unforeseen events.

How do I connect my phone / tablet to the power bank?

Power banks usually have a number of ports that can be used to connect your device. The most common port is the micro USB port that has become somewhat of a standard for android smartphones and devices. iPhones are a bit more unique, as they require their own trademarked chargers.

But, no worries, almost all power banks these days have options for both iPhone and Android ports. However, to be sure what you’re getting, take a look at the specific manual of the power bank just in case.

Cables for connecting your device are usually provided with the power bank itself. However, most of the standard USB to Micro USB cables can be used for Android devices. Apple devices, however, may be a bit more complicated to hook up if you don’t have the compatible port on your power bank.

Why use a power bank?

Power banks are extremely versatile in terms of applicability. They can be used on road trips, camping trips, and mainly anywhere where there’s no power socket available.

Smartphones have become essential to our modern way of life, which means that power banks are extremely popular and can make a hell of a difference if you’re in need of using your phone and/or tablet in a steady fashion.

In the end, it needs to be said that power banks come in various shapes and forms. Some have higher capacities, others charge really fast. Our advice is to think about your personal needs, and get the power bank that makes most sense to you.
