The market especially the online market today is flooded with innumerable brands and companies selling power banks of different features. Though the heavy power banks of smartphones, laptops and tablets can easily be differentiated but to get the best product even in a particular category, you will have to consider some specifications in order to get the best from the rest.

What specifications in a powerbank test?
Specifications in a powerbank tests means different parameters which you have to consider before buying a powerbank. It is very important to pay attention to the specifications before you buy a power bank.
Capacity of the powerbank is perhaps the most important consideration in this whole process of decision making. It is the power of the powerbank and it describes how much energy can the battery provide to a device. The capacity of powerbanks are measured in terms of milli-amp- hours. Different devices require different capacities of powerbanks. For instance, an iphone 7 plus which has a 2900 mAh battery would require for 6000-8000 mAh powerbank to charge at least 2-3 times from the scratch. Similarly a Lenovo Yoga notebook which contains a battery of 8500 mAh requires a powerbank with capacities yp to 20,000 mAh power. So, it depends upon the type of device you are willing to charge with an external battery.
The` charging current` in an external USB battery charger is the next big thing to consider in a power bank. It is measured in Ampere ( A). It determines how fast or swift an external battery can charge a device. Most of the power banks for smart phones have charging current of 1 ampere which is suitable enough to charge a phone in the least time possible. Moreover, some of the tablets and laptops signify for more energy. Interface on the other hand is another specification, which should be observed by every user. Interfaces determine which device would be suitable for the powerbank. Majority of powerbanks only need a USB port which requires 5 Volts, and they can be found in any powerbank.
