A power bank is extremely beneficial. Just imagine the situation when you are expecting a very important business call and suddenly the battery dies. Even the thought of it makes you shudder. Well wouldn’t it be comforting  if you had an alternative device to fall back on during such times? This is where power banks come into play.

Below are a few of the benefits of power banks :-

  1. Charges your phone when it runs out of power and you are not near any electric socket. So, if you are commuting / travelling then this device can be vital.
  2. Portable: This device is neither heavy nor inconvenient to carry. It enjoys high portability because of its light weight and unique design. So commuters / travellers find it very easy to take it along with them in their briefcase or suitcase
  3. Operable for all brands – No matter whether you have a Apple iphone , Samsung, Nokia or any other phone you can use your power bank with it.
  4. Can charge other devices as well – Apart from mobile phones, you can also get other electronic devices charged – iPads, tablets, iPod’s etc.
  5. Robust – Built to stand the day-to-day demands of the commuter / traveller & so the chances of getting damaged are also miniscule!

Some things to consider :-

  1. Capacity

If you’re not carrying too many devices when you travel, then you will only require a portable bank with a low capacity to charge your phone. If you’re charging larger devices, such as an iPad or tablet, then you’ll require a higher capacity power bank.

The higher the milliampere hour (mAh), the more capacity the power bank will have. If you have a cell phone with a 1500mAh battery, then a capacity of 1500mAH can fully charge it once. Here is a usage guide:

1500mAh battery: Mobile phone (1 full charge)
5200mAh battery: Mobile phone (2 full charges), Tablet (50% charge)
10000mAh battery: Mobile phone (4 full charges), Tablet (1 full charge)

Higher mAh unit power banks are also available, and there are charges that can power almost all devices, including laptops, iPads, tablets, iPods, action cameras and all mobile phones.

  1. Portability

Most power banks come with a built-in USB cable, so you don’t have to worry about leaving your devices USB cable at home.

To cater for iOS users, some power banks contain a built-in Lightning cable instead. These often tend to cost more than USB options because they cater for Apple products, where licensing and certification program fees have to be paid.

Higher capacity banks usually come with more than one USB charging port. The biggest advantage of having multiple charging ports is that you can charge more devices at the same time.

If you’re using more than one port, identify the total output current of the battery pack. For example, if you’re using a battery pack with two 2A/5V ports, an output of 2A will be used when only one port is being occupied.

If two ports are connected, the total output may be limited to 3A, with each port getting 1.5A. If a power bank has a total output of 4A, then both devices will be able to charge as fast as they can.

  1. Power output

The output of the charger should be equal to the input battery voltage requirement of your device. If it’s lower, you may drain your device’s battery, rather than charging it.

Most power banks will charge mobile phones and mp3 players, but only a selected few can fully recharge your laptop battery.

Larger electronic devices such as this may require a 12V – 24V output rating that is available in larger portable battery packs.
