How to Choose a Power Bank for Your Mobile?

In order to pick up the right power bank for your device, you need to perform a little analysis mentioned below.

How to Buy a Power Bank in India?

1. Device Type

Do you need a power bank for mobile or tablet? If it is a Smartphone, then what is its battery capacity? How long are you’re getting the charge?

You need to first know these basics while choosing the best portable battery bank.

For example, if you have the Xiaomi Mobile with 3080 mAh battery and use it more often during your business hours, then it would last for 4 to 5 hours. So, you’ll be needing one or two charges per day.

2. Battery Capacity

This is the second thing you’ll have to take care of before buying a portable mobile charger.

When a power bank is charging a device, some of the charge in it is lost while transferring the power.

In basic language, you need energy to transfer energy.

So, the final battery capacity of a bank comes to about 62.9% of the actual value mentioned on the package.

This is why you should always go for a high battery capacity power bank so that you can get more charges.

Based on the above facts, you need a bank with at least 10,000 mAh battery capacity as you can charge your device up to 2 times (considering the rest of the energy is wasted while charging your device).

3. Power Output

Consider buying a mobile power bank with at least 2 amperes and two ports for charging multiple devices at a time.

4. Power Bank Brand

There are many duplicate brands available in the market. So, I advise you to buy only from trusted sellers and well-known brands.

A few popular power bank brands in India are Ambrane, Xiaomi, Anker, Syska, Huawei, Redmi, Realme, OnePlus, iBall, Lenovo etc…

5. Portability

Since you’re already carrying a mobile phone in your pocket, it would become a problem carrying two heavy devices with you all the time.

So, try to pick up the lightweight power banks (if possible).

However, you can find the lightweight devices within 10,000 mAh capacity, but if you go for bigger battery banks (>15000 mAh), then you need to compromise a little on the weight side.

6. Protective Circuitry

Make sure that the power bank you’re looking for fulfills all these requirements like short circuit protection, over charging protection and no overheating issues.

Pro tip: Only choose a power bank with high quality Lithium-Polymer battery for safety and assurance.

7. Power Bank Price

Lastly, if you land on a portable mobile charger with higher battery capacity at a lowest price, then be aware of such devices.

Many OEMs (3rd grade) use refurbished batteries in their devices which doesn’t give you the charge as promised.

Although, a bit expensive, only go for well-known brands. And also check whether your device is UL certified or not.

Where to Buy Power Banks Online in India?

These portable mobile chargers are available both online and at offline stores.

However, you’ll find that the offline stores are selling them at a much higher price compared to the online stores.

Don’t worry about the shipping charges, as most of the well-known shopping sites provide free shipping and will deliver the item to your doorstep within 2 to 5 days (depending on where you live).

How to Charge a Power Bank?

Charging a portable battery bank is pretty straightforward. The device includes a microUSB port and a charging cable.

Simply, insert one end of the USB cable (microUSB) into the port and the other end (regular USB) into a wall-mounted USB charger or a laptop.

There is an indicator on the device that lets you know whether the power bank is fully charged or not.

Once it displays full capacity, you may disconnect the cable from the charger and use it again to charge other devices.

How to Use a Power Bank?

Generally, all the best power banks come with a power on/off switch, which also lets you know the battery percentage left in the device.

You’ll find the USB ports on the battery bank and you need to connect your mobile to the powerbank using the cable provided in order to initiate the charging process.

Once you completed charging your mobile, you can disconnect the cable and switch off the bank. It is that simple.

The number of devices you can charge simultaneously depends on the number of ports present on your portable bank.

Few low cost devices come with single port, while most come with either two or three USB ports.

Different Types of Power Banks

The powerbank or external mobile charger is basically a rechargeable battery with a special circuit that manages the power flow between different devices.

There are 3 types of power banks in the market.

  1. Universal Power Bank
  2. Solar Power Bank
  3. Old Style Battery Case

Despite the type of the battery bank, the purpose served by all of them is the same.

They’re designed to charge your electronic devices like mobiles, tablets, laptops, digital cameras etc…

The only difference lies in how these power banks are being recharged.
