Best Power Banks in India - Buyer's Guide
In this section we are going to discuss about the various parameters that you should consider while buying a Power Bank so as to make your purchase the best one in the market.
As we have already seen that there are lots and lots of Power Banks available in the market. At times it can be very difficult for you to figure out which is the best power bank in the market. We should take proper care while buying a power bank because there are tons of fake power banks available in the market which charge only 2 to 3 time.
Without further ado let us directly jump into seeing the tips that you should consider while buying aa power bank.
1. Capacity of the Power Bank
One of the most important factors while buying a Power Bank is its capacity. The capacity of the Power Bank is measured in mAh or milliamps per hour.
The capacity of a power bank denotes that how much charge is stored inside a Power Bank’s battery. Usually Power Banks vary from a capacity of 1500 mAh to 15000 mAh, 20000 mAh and even 30000 mAh too.
Now let us understand the meaning of mAh while buying a Power Bank…
Suppose you have a mobile phone or a tablet whose battery is of 2000 mah and you are looking for your Best Power Bank for mobile phone or tablet, then I would advise you to go with a power bank that has at least 10000 mah capacity.
Why this advice?
Well the answer is simple…
Because there are certain losses that are involved while transferring the power (electrical energy) from power bank to the mobile phone’s battery,which leads to loss in an efficiency of power bank capacity.
Ideally you get an efficiency of 70 percent to 90 percent depending on various factors which means that you will get 7000 mah to 9000 mah power from a 10000 mah power bank.
Thus my advice would be to buy a power bank that has triple or even quadrupled(4 times) capacity as the battery of your mobile phone.
Let us consider one more example…
Suppose we have a phone battery with 2750 mah capacity. A Power Bank of 5000 mah can be a good match so as to charge the phone 1 time because due to energy losses in the conversion process, the Power Bank will yield 3500 to 4500 mah.
But if we have a phone whose battery is 3500 mah, then a 3500 mah power bank cannot charge the mobile phone completely.
Thus the higher the mah a particular powerbank has, the more it has the capacity to charge your mobile phone.
Please note that a power bank achieves its best performance after 7 to 8 chcarge-discharge cycles. So, if your power bank is giving less efficiency after 2 to 3 discharge cycles,then you don’t need to worry.
Buy a Power Bank that suits your needs and requirements (Capacity).
2. Number of Output Ports
If you are an office going person or a businessman, then you might be carrying more than 1 mobile phones. What if both mobile phone batteries goes down…
…Here comes the usage of number of output ports. If you have two or more than two output ports in your Power Bank, then you can charge two mobile phones at the same time. For this, you have to buy a Power Bank with multiple ports.
Power Banks with Multiple Output Ports can be costly.
If you are a student and you want to charge your friend’s Smartphone then also you need multiple output ports in your Power Bank.
3. Multiple Connector help in Pass Through Charging
Third feature that you should pay close attention to while buying a Power Bank is connectors. It is recommended to buy a Power Bank that contains built in cable.
One important feature that a power bank should contain is Pass Through Charging. When you buy a power bank, you get a usb cable only. You have to charge the Power Bank with the help of the power adapter that came with your mobile phone or smartphone.
Now you might not like to travel with two separate power adapters-one for power bank,another for mobile phone. This is where the Pass Through Charging comes into picture.
What you can do is connect the one end of the power adapter to the electrical socket present in your house and connect another end of power adapter to the power bank. At the same time, use the cable that came with your Power Bank. Connect the power bank with your mobile phone through that cable.
What this does is first the energy is transferred to the mobile phone and then your power bank gets energy in it. You can take advantage of this pass through charging feature by making this setup in the night and when you wake up in the morning, you will see that both the power bank and the mobile phone is also charged.
This pass through charging is present in some Power Banks. Imagine that you have two or more than two output ports in your power bank, then you can charge multiple smartphones with that power bank during night.
Isn’t this a great feature in Power Banks.
4. Types of Batteries
It is very important to know the types of battery that your Power Bank contains.
There are two types of rechargeable cells found in the power banks. One is Lithium-Ion battery. Second is Lithium-Polymer battery.
Lithium-Ion cells are more popular because they are older generation, cheap and easily available.
The mah capacity of lithium-ion cells are generally limited.
On the other hand,Lithium-polymer cells are safe and they are not heavy too.
5. Portability and Weight of the Power Bank
If you ask me what is the first thing that anyone should closely look for while buying a power bank is its portability.
Your Power Bank should be light weighted and portable. A light weighted Power bank can be easily carried with us in our pockets, bags etc and hence it becomes quite handy to carry. The Power Bank should have lesser physical dimensions too because then only it can easily fit in our pockets.
Imagine if a power bank was of a size of a computer,then that would have been impractical to be called as portable.
6. Safe Protective Circuitry
If you are in a local market or you are thinking to buy powerbanks from road side markets,then please stop. They might not give you the best power banks. They might be fake power banks too. You might see power banks of branded companies for smaller prices there but this is a red signal tos top there only as that power bank might get overheated and can harm your phone and it might be damaged one too. So,I advice you to buy powerbanks online only.
Please ensure that your powerbank provides the following protection:-
(i)Protection to overcharging:-If your powerbank has overcharging protection,then when your power bank gets fully charged,then it will automatically cut off the power supply to prevent overcharging. This feature can be helpful when you make the charging to power bank on and some how you forget about it.
Power Banks have a led at the upper base. It glows Whenever we connect a power bank to electrical power supply, we can easily see a light that flashes on one of the leds and more led start glowing as power bank gets more and more charged.
(ii)Over Voltage protection:-When ever the supply of voltage in your house exceeds the input voltage of the power bank,then this feature can be helpful.
(iii) Over heating protection:-You can check for over heating protection of your battery charger. This feature avoids over heating if you are in a very hot place where the temperature is high.If over heating is not there in the power bank then it might cause a harm in high temperature environment.
(iv)Short circuitry protection:-Power banks also give this short circuit feature which can help in a situation when short circuit occurs.
You can safeguard yourself from buying a fake Power Bank by FCC,RE AND ROHS certifications. A power bank gets FCC and ROHS certifications only when certain tests are performed on it. Tests include if a Power Bank is prone to explosion or not and whether proper circuitry is maintained while the manufacturing of a power bank.
7. Price of the Power Bank
Pick the Power Bank that suits your budget as well as your requirements like capacity, number of output ports etc. Don’t compromise with features just because the price is high.
8. Warranty Certifications
You can check for the warranty of a power bank. Normally a branded power bank comes with a 1 year warranty. You can also check for a service center availability in your city so that if any problem comes after buying power bank, you can easily get it repaired.
9. Current Ratings of the Power Bank
1. Input Current of the Power Bank
Input current is important as it measures the amount of time in which our power bank is recharged. If the input current of our power bank is low,then it might take 8 to 9 hours for our power bank to be charged fully. Current is measured in amperes(A).
There will be times when you have a power bank that has 2.1A input current. But the charger of your wall supports only 1 A,then you should upgrade your wall charger as with the current charger it can take long time to recharge your power bank and you never know when the need of the power can come.
2. Output Current of the Power Bank
In some power banks the output current rating is 1A. On the other hand there are some power banks which have 2.1 A output current. You can read about input and output current on the power bank itself as it is printed on it. Some mobile phones have 1 A input rating to draw current to its batteries and some smartphones also have 2.1 A input rating to draw current.
Now a days there are many power banks in the market which are able to find out the input rating of a mobile phone and adjust output rating of power bank accordingly. These power banks are recommended because they charge our mobile phones faster and also don’t push more to smartphone than required.
Please note that there are certain mobile phones which support qualcomm quick charge feature. This feature means that it can charge your phone in less time than expected.
If you have a charger and a mobile supporting this quick charge feature, then you can look for a power bank that supports quick charge feature. Not only will this quick charge supported power bank charge the power bank quickly, but this power bank will also charge your phone
