Power banks are a lifesaver when it comes to charging your phones at those parties or when you’re somewhere where you do not have the luxury of using an electrical plug. Power banks make for a great gift for others as well as for oneself. Read on so that I can help you choose the best power bank available out there.
Before starting let’s define what ‘Power Bank’ is in simple words. A Power bank is a device that can supply power from its built-in batteries through a USB-port. Power banks commonly use a lithium-ion or a lithium-polymer battery.
Things to look for before purchasing a power bank:
Power Banks come in various capacities. But the most common ones come with a battery size of 2,500mAh, 5,000mAh,10,000mAh, 15,0000mAh and 20,0000mAh. The capacity of a Power Bank is measured in milli-Ampere per hour which is same for smartphones. It is advised to buy Power Bank of 5,000mAh and above capacity because most modern gadgets come with battery size of 3,000mAh and above.
Types of Batteries:
Lithium-Ion and Lithium-Polymer are the most common types of batteries found in Power Banks. Lithium-Ion batteries have limited use as they come with lots of limitations. Lithium-Polymer cells are commonly found in modern Power Banks because of their long lasting life safety feature.
Number of Ports:
Most power banks come with either one or two output ports. If you use more than one gadget that needs charging on daily basis, power bank with two ports should be your priority. Based on the number of gadgets you have, choose the correct Power Bank.
Types of USB ports:
The most common Power Banks come with a combination of Micro-USB B as input and USB A-type as output. With USB Type-C considered as the future of USB ports, we are seeing new Power Banks come with Type-C ports. Most Android phones come with Micro-USB B or Type-C port and they can be charged with Power Banks having USB A-type output port.On the other hand, iPhones with Lightning port can be charged with Power Banks having USB A-type as the output port. Based on the USB port your phone has, choose the correct Power Bank.
Buying a higher capacity Power Bank is good but it should not take too much time to charge that you will have to think twice before charging. Input ampere rating is something that determines how long it will take for a Power Bank to get fully charged. The input ampere rating is either 5V-2A DC or 5v-1A DC. Looking at the numbers one can easily tell that 5V-2A DC will take less time to charge.
Output rating is nothing but how much power a power bank can deliver to the phone. Most Power Banks come with a minimum rating of 1A. Output rating becomes important for Power Banks with two ports. One port of the two should have a min output ampere rating of 2A.
Pass Through Charging:
When it comes to Power Banks, this is the most underrated feature. Pass through charging is basically the ability of a Power Bank to charge itself and charge other devices at the same time. If you are a person who keeps his phone on charge overnight, this feature should be your priority.
Power Banks come in various size and shape. Due to recent advancements, Power Bank sizes are getting smaller as more companies are using higher density batteries. The size of a Power Bank should be such that it can be easily fit in your pocket. The smaller the Power Bank, less is the hassle to carry it.
