<img src="how-to-choose-best=powerbank.jpg" alt="how to choose best power bank for you">

If your mobile battery is 3000mAh & power bank is 6000mAh then never think that it will charge your phone battery twice.

Charging depends on both batteries efficiency. (battery of phone & battery of power bank)

If your phone battery is new & original then it is a good idea to buy a power bank. Old & duplicate batteries cannot store much current in their body.

TIP-1: Buy power banks from famous/branded manufactures

For the company's sake, famous companies will try to serve you good quality products.

If you buy power banks from cheap manufacturer's then they will serve you defective products.

Defective batteries can take your life anytime.

TIP-2: warranty & certificates

A product providing warranty it means it is reliable. Buy a power bank which assures warranty.

But if it is proving good certificate without any warranty then you should trust more on the certificate.

(If you have a removable battery then you can check it has many types of certificates like below image)

<img src="mobile-battery.jpg" alt="mobile battery safety certificates">

While choosing a battery you have to keep in mind that the certificate is better than a warranty. (because certificate indicates the safety of a battery)

If your power bank has both a safety certificate & warranty then wait to grab it. (READ TIP-3 BEFORE GRABBING)

TIP-3: Li-ion OR Li-polymer battery?

Li-ion is dangerous, cheap & lightweight

Li-po is safe, expensive, longlasting & heavy

You will never face overheat/ blast-related issues if you buy a Lipo power bank.

TIP-4: VOLTAGE/AMPERE

Check if the power bank has high input/output A (AMPERE)

A high input ampere means it can charge itself (power bank) faster & a high output ampere means it can charge your mobile battery faster.

Normally 5V/1.5A is for mobiles

For tablet & MORE BATTERY CONSUMING DEVICES, it can be 9V/2A OR 12V/2A

✔️✅#Check your mobile battery if it is written 5V (output) then choose a power bank which has 5V/1.5A output

Never use power banks which has 9V/2A or 12V/2A for mobile. It can damage your battery or worse can blast your battery.📵

TIP-5: USB, ALUMINIUM OF A POWER BANK

If power bank has more than one USB (TYPE -C IS THE BEST) then you should consider to buy it. Never buy a power bank which has a single USB.

Aluminum lasts longer than plastic. If your favorite power bank is made up of aluminum instead of plastic then it is a good idea to buy it.

TIP -6: Safety features In a power bank

Modern power banks have safety features that can save your power bank & phone battery from short circuit & overcharge.. If your beloved power bank has this feature then consider to buy it.

TIP-7: Conversion rate & phone battery health

When a 10000mAh power bank charges a 5000mAh phone it losses some charge during the process of charging. It is due to external factors like heat, the resistance of wire etc.

The more conversion rate a power bank has the more it can charge your phone.

It means if you have a newly bought phone with a good battery(5000mAh health then a 10000mAh battery power bank (with a conversion rate of 90%) can charge your phone 1.62 times.

<img src="formula.jpg" alt="formula showing how power bank works">

The formula for it is:- BATTERY CAPACITY OF POWERBANK(mAh) ✕ CONVERSION RATE OF POWERBANK✕ HEALTH OF MOBILE BATTERY /CAPACITY OF MOBILE BATTERY (mAh)

Suppose,

Battery capacity of powerbank= 10000mAh ***Health of battery means how much current it

Battery capacity of the phone = 5000mAh can accept from the power bank***

The conversion rate of the power bank = 90%

The health of mobile battery = 90%

According to formula,

10000mAh✕ 90%✕ 90%/5000mAh =1.62 times

TIP-8: Additional features

Buy power bank which has different lights for indicating different types of situations like full charge, battery full & low battery.

It is a good idea to buy if it has LED LIGHT & charging pin.

TIP-9: Loss of charge when not in use

If power bank losses charge even when it is off then it is not ideal for you. Simply avoid them..
