A Wallet-Sized Power Bank Perfect for Your On-the-Go Lifestyle
What Is a Power Bank?
One of the significant tech devices of today is the power bank. A fast-charging, large capacity mAh battery power bank should always be in a traveler’s bag.
After all, how would you feel if you wanted to capture every moment during your holiday trip with your loved ones but the battery of your device suddenly decreases or shuts your device off? To make it worse, imagine that there’s no electric socket or port nearby.
Plus, even if you do find a socket, you can end up missing out on beautiful moments because your mobile will take some time to reach a sufficient charge level.
It’s during these times that power banks become handy and you’ll be grateful that you packed a fully charged power bank with you.
The device functions like an extended battery. It stores electrical energy you can use to restore your phone’s battery wherever you are in the world.
Some people may compare it with an external battery pack, but they differ in the following ways:
- Longer Battery Life — This device can store power for more than 5 hours. If you don’t use it often, it can even last for a couple of days.
- Flexibility — A battery can be limiting. It may work only on a specific cell phone, for example. If you upgrade your smartphone, you may not be able to use the battery anymore.Power banks can work on different types of mobile devices. You can even use them on both Android and iOS devices.
If you change your smartphone or tablet, you may need to change only the charging cable (e.g. lightning cable for iOS devices).
- Portable Power –- Some power banks can be bulky or heavy, but these days, you can already purchase or use a power bank card. It fits right into your wallet or purse.The portable power bank will not look odd with your stylish new smartphone, because this credit card-sized device is really thin and looks smart.
- Efficiency: External battery packs may provide you with the power you need, but it won’t last very long. On the other hand, you can use a high-quality power bank multiple times in a single day.In fact, depending on your power bank’s capacity, you can even use it to charge different devices alternatingly or simultaneously. Meanwhile, a portable battery pack only has enough cells to run one mobile device before it runs out of juice.
- Convenience: With the advancements of power banks, a lot more tech-savvy individuals rely on this product than external battery packs.Different power banks offer varying features. This variety allows consumers to get the device that suits their specific needs. For example, instead of carrying around a bulky flashlight, you can opt to get a portable power bank with a good LED torch light.
On the other hand, travelers saving up on space can opt to get wireless power banks or small, card-sized ones that don’t take up much extra space. You can even carry most of them in your pockets.
mAh Definition: mAh stands for milliampere-hours. It refers to the capacity of the batteries of small devices such as power banks. Bigger batteries will use Ah or ampere hours.
Why You Need a Portable Power Bank
The relationship between mobility and the popularity of mobile devices have already been a subject of many types of research.
For one, there’s a direct correlation between the two. The more mobile devices there are, the more mobile people become.
With mobility, though, is the need to travel light. The thinner the device, the better.
In fact, it’s one of the reasons devices with lithium-ion batteries are the norm. Lithium-ion makes devices efficient while keeping them lightweight and easier to carry around.
Do you know how much time a person spends on their mobile device? On average, it’s about four hours or 16% of your day!
However, with this much time spent, are batteries able to keep up? According to research from mobile technology company Phone Arena, battery life dropped significantly, especially between 2015 and 2016.
Based on the same data, it went from around 460 minutes in 2015 to close to 420 minutes the following year. This didn’t take into account the kinds of activities people love to do with their phone.
These included watching videos, tinkering the apps, playing games, or getting busy on social media. In other words, they don’t just call or text. These activities, therefore, can drain batteries fast.
Although charging times sped up, based on Phone Arena analysis, it’s not always a guarantee you will have the chance to recharge your device. After all, you need a power outlet to do that.
A power bank ensures you can have power whenever you need one no matter where you are going.
3. Device Ownership
Check out tech stores, and you’ll find dozens of devices.
You can already buy a laptop aside from (or instead of, depending on your lifestyle and work requirements) a desktop PC, as well as a tablet, smartphone, and an e-reader. You may also invest your money in fitness trackers and smartwatches.
It’s not surprising a person connects themselves to an average of 3.2 devices, according to Global Web Index. In fact, this level of ownership is prominent even among older adults, who tend to be less receptive to technology.
The ownership of multiple devices makes a power bank more valuable. It is a perfect complement.
If the phone loses power, they can charge it with their power bank while using other available devices, which may be using the power outlets.
These days, people stay connected through their devices wherever they are and whatever they’re doing. This includes traveling and even doing outdoor activities, such as camping.
Even in the middle of the woods, people still use their devices to stay connected to the rest of the world. This is where a power bank will prove to be useful.
For example, a campground may not have a reliable electrical supply, but you can always rely on a power bank to provide juice to your devices.
The excellent thing about using a power bank is you are not dependent on the available electric supply. If you run out of power, plug in your device, and you can charge a phone or a tablet in the middle of a forest.
If you’re traveling abroad, other countries may have a different power outlet configuration. No matter where you are, you can use a sturdy, reliable power bank.
If you use a USB power bank, can stop worrying about whether your phone charger matches the outlet or even meets the voltage criteria of the country.
5. Getting Through Emergency Situations
These days, having a portable charger may already be a necessity. With everyone relying heavily on their mobile and electronic devices, it’s too much of a handicap to have a gadget die out on you during a bad time.
Just think about how much data you won’t have access to if you lose your phone’s battery power. At the very least, you might not be able to reach your emergency contacts during dire situations.
To prevent and avoid different emergency situations, it’s safe to always carry a power bank with you wherever you go.
Note: Even if you do have a power bank with you, make sure that you know how long your device usually lasts. This will help you gauge what you can and can’t do when you don’t have access to an electrical socket.

A power bank can come in different shapes and sizes. You can choose between small and big models that offer various features.
Perhaps one of the best power bank designs out there is the credit card-inspired one. It’s often made out of both plastic and metal parts.

How to Choose a Card Power Bank
It’s safe to say these days you need a slim and portable power bank. It’s one of the ways to guarantee you will have a stable supply of power anytime and anywhere.
Even this device, though, can vary from one another. To know which to buy, consider the following:
1. Battery Capacity
As mentioned, you measure the capacity of a power bank according to mAh. It can range from 2,000 mAh to as much as 10,000 mAh (or even higher). The bigger the number, the more charges you can make with them.
It also depends on your level of phone activity or how much power you need to use it fully. A big device that uses a lot of electrical output will need a power bank with a huge battery capacity.
2. Capacity of the Power Bank Charger
Power banks can also drain their battery, so they need chargers themselves, such as cables. These, though, can have different levels of power output.
The smaller their Amperes are, the longer it may take them to recharge a power bank. In some cases, it may take about 3 to 10 hours.
3. USB Ports
Bigger power banks can have dual USB ports and usually have a larger charging capacity. It means you can recharge two or more devices simultaneously.
Meanwhile, for wireless charging, you can get power banks that don’t have USB ports. These often use Qi charging pad in place of wires and cables.
Note: A credit-card-sized power bank may not have this feature. Slim, card-sized power banks are usually best for travelers who only plan to charge their own cellular device.
Qi Charging Pad Definition: A device that allows wireless power transfer through inductive charging methods.
Do you know you can use power banks as promotional materials? If this is your intention, the thin credit card-sized devices are excellent.
Brands running marketing campaigns, hosting seminars, or setting up at trade shows can give out a few of these card-sized power banks. It has enough space for your logo so your customers will always have your brand in mind.
These are definitely a step up from the usual flyers, button pins, pens, and notebooks that customers throw away after a few days. Imagine it: every time someone whips out the power bank you gave them, there’s a chance for your brand recognition rate to go higher.
