how to choose a power bank in India?

Power banks usually contain a cylindrical lithium ion or lithium polymer battery that gets power through a dedicated USB input socket. It uses mini or micro USB ports for charging other devices and a full-sized USB port for discharging.

There is a DC-DC step up transformer inside a power bank that boosts the output to 5V so that it can charge high-end smartphones.

The total time required to fully charge a power bank depends on its capacity. While power banks with low mAh take 3 to 4 hours to charge, power banks with high mAh take 10 to 15 hours to charge.

  • Output USB Port/s – A power bank may have one or more USB output ports. Output ports connect to mobiles, tablets and other devices, carry power from the power bank and charge these devices. Out ports may have varying rate of power output – some supply 1Amp power others supply 2Amp power.

Those who like to travel and spend a lot of time in buses and trains should get a high capacity power bank.

How to Choose a Power Bank?

  • Capacity of Power Bank – First step is to ascertain the battery capacity of your phone and tablet. Make sure the battery capacity of the power bank you are choosing is more than the battery capacity of your devices. The mAh of the power bank you buy should be at least twice the battery capacity of your mobile.
  • Conversion Rate – The capacity and efficiency rate of power banks is not the same. Most power banks have 50 to 60% of the stated capacity. This happed due to conversion of the charge from the battery to your phone and loss of power from the power cable.
  • Type of battery – Pay attention to the type of battery used in the power bank. Most power banks use either lithium ion or lithium polymer batteries. Lithium ion batteries are cheaper and easily available while lithium polymer batteries are more expensive but supply twice as much charge density per unit weight.
  • Output Current in Amperes – It is crucial to note the ampere rating of the output port of the power banks to make sure that your devices charge well. Lowe end power banks have output port with 1A rating and higher end ones have 2.1A rating. Older phone batteries don’t draw more than 1A current but advanced phones and tablets need 2.1A input current.
  • Input Current in Amperes – Input current is important for the charging time of the power bank. In case of low input current, a large power bank will take 8 to 10 hours to charge. Although, some power banks do have 2.1A input current, but the wall charger might only be able to supply 1A output. In such cases, it is recommended to upgrade to a better wall charger.
  • Number of Ports – Higher number of ports allows the user to charge multiple devices simultaneously. Most power banks with higher capacity usually have more than one USB charging port.

From the above discussion it is evident that a power bank is an essential gadget that is needed to charge your smart phones and tablets while you are on the run. You can choose a quality power bank from the list and don’t forget to share your experience with us.
