2) Power Bank Battery Size
The battery is the heart of power bank. Check the battery size of all the power banks available in the budget. What is the battery size of the power bank that you are going to need? Usually, battery size is indicated in mah ( mili ampere hour). More it is more powerful will be the power bank. For example Intex 11000 mah power bank comes with 11000 mah battery.
Typically people prefer 10000 mah power banks. A 10000 mah power bank can charge a mobile with 2500 mah battery three times. If you requirement is only to charge 1 or 2 times, then you can even consider 5000 mah power banks.
3) No of USB Ports for Charging
Some power banks have 1 USB port, some have 2, a few have 3. Before choosing any power bank, you should check your requirement. If you are the only one, who will charge mobile. Then 1 USB port is enough for you. But if you have to charge 2 or more devices simultaneously then you may consider two ports.
4) Power Bank Efficiency
You must check what is the efficiency of the power bank that you have shortlisted. Good quality power banks have around 80 to 90% efficiency.
For those who don’t know what is efficiency. Let’s understand efficiency in a simpler way. Suppose you buy a power bank with 10000 mah battery. Now if you think that this power bank will give you 10000 mah useful output power, then you are wrong. In power banks, some power gets lost in the form of heat due to circuit resistance.
If above power bank has 80% efficiency, then you will get around 8000 mah useful output power. So higher is the efficiency better it is.
5) Power Bank Charging Speed
Nobody likes slow charging. Slow charging is suitable for the mobile battery. But who has the time to wait for mobile charging. So check the USB port output rating. 1 to 1.5 A current is enough for small mobiles. But for tablets and high-end devices you should choose power bank with more than 2 A output current. If your device has more than 2200 mah battery, then you should choose the model which have more than 2 A output current.
Above paragraph is about mobile charging using power bank. Now coming to the power bank charging. A good quality power bank with 10000 mah battery takes around 8 hours to charge fully. Though charging rate also depends upon the charger, you are using to charge it. Nowadays big brands like Moto, Asus are giving turbo chargers with their handsets. Turbo chargers can charge a 10000 mah power bank in 5 to 6 hours.
6) Brand Value and Customer Support
Brand value is the quality level of brand. No of people using their products reflects the brand value. If a company has good brand value then it is obvious it would have good customer support. You should look whether the company have a service centre nearby your location. If yes, then what is the service standard it offers to its customers.
7) Ask Experienced Person
Configuration written on paper is not the final thing. Built quality and brand value also matter a lot. You can not find out the build quality of a power bank just by seeing its configuration. A person who has some power banks can tell you about user experience.
