How Powerful Is Your Power Bank?

With the evolution of smart phones there have been numerous articles on how to reduce battery drainage, what apps on your phone drains your battery faster, so on and so forth. At the end of the day it always comes down to the battery. What bullets are to guns, battery is to your smart phone. This small device which possesses the power to convert chemical energy to electric energy gives your smart phone POWER and quoting Spiderman "With great power comes great responsibility."

What we are trying to say is, these rechargeable batteries, without which we are socially impaired in today's world are an important device in our smart phone. Since we cannot tune out the apps (to save on battery), which make smart phones smart, we can always resort to using portable USB battery chargers or Power Banks. Our duty lies in selecting the right device for our phones and how powerful the Power Bank is.

Smart Phone users are rapidly gravitating towards Power Banks because they are portable and can be easily charged with the phone charger, computer USB port and chargers supplemented by the device as well. For the more ecologically inclined crowd there are also Solar powered Power banks.

These rechargeable batteries of Power Banks are made up of Lithium ion and their capacity is measured in Milliampere-hour (mAh), though these terms tend to intimidate us, but these are very basic and simple qualities that we need to understand before we delve into measuring the power of our portable USB chargers.

Milliampere-hour (mAh) is nothing but a thousandth of an ampere hour, which is a unit of electric charge, equal to the charge transferred by a steady current of one ampere flowing for one hour.

Since the PowerBank stores power in the form of DC current, it clearly charges your Smart Phones much faster compared to AC chargers a.k.a the Smart Phone chargers which accompany your Phone, reason being these AC chargers because they transfer AC current to DC, the flow of current is not steady, thus takes longer to charge than a Power Bank which charges your phone with its DC output and with its steady flow charges your devices much more efficiently and faster.
