How To Choose Right Power Bank For Your Device?

Who doesn’t like using smartphones? In this day and age, not using a smartphone is almost like a handicap for a working professional.

However, no matter the worth or the quality of our smartphones, without charged batteries, they are of no use than being a ridiculously heavy paperweight.

Thankfully, we have power banks to charge our smartphones on the go, but choosing the correct power bank for your phone is no less a task either.

If You Guys Don’t Want To Read The Entire View, Just Scroll Down, You’ll Find Just The Tips For Buying A Powerbank.

Q1: Why to choose power bank for your phone and tablet?

Mobile Devices like smartphones and tablets make life so much easier. That is , until they run our of battery power when there’s nowhere to plug in.

Q2: What you will benefit while choosing a perfect power bank for your phone?

Well, a lightweight power bank you can carry anywhere. Simply charge it up at home, throw it in your bag or your pocket, and connect it to your phone whenever it needs a quick battery boost. You’ll never suffer from “low battery anxiety” again.

Q3: How to choose power bank for your phone/tablet?

How to choose power bank for your phone and tablet? Surely, it could be easy for you as you could just follow these tips below one by one; while it would be a little hard as you have to read and check the tips carefully, covering up to eight aspects in total, the size/capacity of power bank, power output, number of USB ports, cables included, power input, safety, quality and certification.


Let’s start by choosing the size of your power bank.

This is not about which one will fit in your pocket or your purse. The size of the battery is about the power inside. Most power banks will feature a number on the front that tells you the number of mAh or “milliamp-hour”.

Common sizes range from 2,000mAh up to 10,000mAh or even 26,000mAh. Bigger numbers mean more power and more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.

We’ve used smartphones and tablets to compare battery sizes, but most power banks will charge any device that charges via USB, such as a GoPro camera, Kindle reader or Bluetooth headset. Bigger devices that draw more power will need bigger batteries – more mAh – to charge them fully.

Question: How many times can a Power Bank 20,000mAh fully charge your phone?


Q4: your power bank will come with a cable.

A cable to charge the battery: YES

Every power bank should come with one cable (usually a standard USB to Micro-USB cable) to charge the power bank itself, which you use to connect the power bank input port (usually Micro-USB) to a standard USB wall charger.

A cable to charge your phone/tablet?


If your phone or tablet connects via Micro-USB, you can use the supplied cable to charge it.

If your phone or tablet connects via a Lightning or USB-C connector, you will need to use an additional cable to charge it. Some power banks come with multiple cables and you could check the packaging to see what’s included.


Some power banks provide cables that are detachable, which makes it easy to switch between cables for your iPad, your Samsung phone, your Kindle or another device.

Some have cables that’re hard-wired to the battery that they cannot be detached, making them easier to find in a low battery emergency, but may make them less versatile overall.

Some even have clever storage solution: a detachable cable you can switch out for other cable, plus a way to keep the cable close so it’s always close at hand.

Q5, It’s about charging the power bank itself.

Unfortunately, no power bank has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge: plug the supplied cable into the input port on the power bank and a standard USB on the other end into a wall charger or other power source.

Power Bank input ranges from 1Amp up to 2.4Amps (short for ampere and it’s a unit of current). Put simply, the bigger the input number, the faster it will recharge.

Some power banks have an LED indicator, which tells you how much power the power bank has left and on the other side will tell you when you need to recharge the battery.


What’s more? Here’s something about how to choose a safe power bank.

It’s easy to avoid counterfeit and dangerous ones by following these simple steps:

Register Your Device some power banks require you to register your purchase, by providing the serial number either online or via a helpline. This is a good way to activate your returns policy and to ensure your product is not a counterfeit.

Check the Warranty manufacturer, country of origin and the type of battery may mean differences in the type or duration of the warranty. If you are unsure, check the small print on the package or the instructions provided.

Something else? Surely. The Importance of Quality.

Safe power banks should have undergone the following testing.

Efficiency   more efficient power bank is, a lower operating temperature it will have, which wastes less energy for a longer life expectancy.

Over Current Protection:   This prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.

Over Voltage Protection:   it protects both the power bank and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection:   some power banks consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures   While using batteries in extreme temperatures isn’t advised anywhere.

Last but least, it’s CERTIFICATION.


These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.

So, have you got a clear idea about how to choose power bank for your phone and tablet while reading through the passage? Hope This Helps!

Just The Extra Tips: In Short:

  • First and foremost, you need to know about the battery size and the charger specifications of your smartphone. You would find it printed on the battery and the charger or on the box in which your cell was packed.

  • The power bank that you buy should at least have the same size as our device battery. This would ensure that your battery gets fully charged at least once with the power bank. However, if your phone frequently runs out of battery, get the highest mAh power bank that you can afford so that you have enough battery stored for emergencies.

  • The output voltage of the power bank should be equal to or higher than that of your device.

  • Depending upon the number of devices you carry, look for the number of ports and cables that your power bank should come with. This would let you charge more than one device at a time, saving you time.

  • To ensure safety of your costly smartphones, choose a power bank that comes with a power-cut power in the event of a short circuit.

  • For a longer life of your power bank, look for the auto-cut feature in your bank. This would prevent it from getting overcharged.

  • Sometimes, it is useful to spend a little to save you further costs. Always go with a branded power bank from a trusted seller. Avoid being fooled by tall claims and regretting later. A power bank can cost you your beloved smartphone.

Happy Charging!
