For people who travels a lot and use their phones much have a hard time charging their phone in the middle of journey.

Power Bank is a portable charging device that contains a big battery, which is used to charge your Smartphone or Tablet. It is a very handy device when you are traveling and need emergency charging of your phone. Power Banks comes in different capacities, brands and features. So, It becomes very difficult for a person to decide which power bank he should get and whether it is a reliable one or not, because a cheap, local and unreliable power bank can pose a great deal of damage to your Smartphone components and its battery. So in this article I will tell on how to choose good and reliable Power Bank for your Smartphone or Tablet.
What to Look for in a Good Power Bank
Here are the most important things that you should look for before buying a Power Bank for your Smartphone or Tablet.
Battery Capacity
Power Banks mainly comes in two capacities, first in the range of 4000-5000 mAh and second one in 10000 mAh range. The more is the capacity of a power bank the more it can charge your phone or tablet multiple number of times.
4000 – 5000 mAh Power Banks – Mainly for Smartphones with battery less than 2000 mAh
10000 mAh Power Banks – For bigger Smartphones and Tablets having battery of 2500 mAh or higher e.g. Samsung Galaxy S4/3/Note3/2, iPad etc.
Number of USB Charging Ports
If you carry more than one Smartphone and need to charge them at once then you should look for a Power Bank with two USB output ports. Here you should remember that a power bank having two USB output ports will charge your phone faster in one usb port than the other because one usb port gives output current of 1A and other one will have 2.1A current on it.
It must be noted that only Power Banks having 10000 mAh capacity can come in two USB output ports option.
Protection & Safety Features
If you want to be on safer side or you really care for your expensive Smartphone / Tablet then you should look for the various advanced safety features in a Power Bank that are being mentioned below.
OCP – Over Current Protection / Over Charge Protection
OVP – Over Voltage Protection
SCP – Short Circuit Protection
ODP – Over Discharge Protection
LED Indicators for Battery Status
The Power Bank must have LED indicators to display the state of charging and discharging i.e. battery status, so that you can get an idea when to charge your Power Bank.
Some Power Banks also have LCD display to indicate the battery status and other relevant information such as current and voltage.
Other Features
Other features include a LED torch and power management features like auto power off etc.
Brand
Last but not the least is that you should always go for a good branded Power Bank rather than cheap, Local & Chinese ones. Some reliable and good brands for Power Banks are PNY, Samsung, Sony, Boat, ADATA, Philips, Asus, Portronics, iHave etc.
Must Read:
How about charging smartphone from power bank, instead of the main points for daily regular charging? Since, our electrical supplies ( voltage ) are notorious and always fluctuates, charging using power bank is safer option. In case of high voltage, the cheaper power bank may get damaged instead of smartphone ( assuming the adapter too fails to protect) . However, the downside is, the power bank may itself loose its juice at the earliest.
If you do regular charging from the Power Bank then it will shorten its life so i would not recommend it.
