How To Choose Best Power Bank With Smart Technology？

Sometimes we don’t know that how much the smartphones changed our life, although a lot of people claimed that smartphones kidnapped their life, so that they didn’t use smartphone over one year and their life got better. But actually is that true? Just like the famous quote:” Instead of wondering when your next vacation is, maybe you should set up a life you don’t need to escape from”. You may turn a smartphone into a great productivity tool or you may think the smartphone is just a devil, who is eating your personal life every day.
But how do you feel, when you have a video call with your family member or friends, who you didn’t see for months. Do you think the smartphone and other mobile tools make us closer?
But we should say that no matter what kind of the brand (iPhone, Samsung or other brands) or operating system of our phone we have, we all have same problem that our phone batteries are running out so fast. But luckily we have the solution: portable charger aka. power bank. Thanks to the development of Industrial manufacturing, we have now tiny power bank but which can charge our power hungry device faster.
But what parameters of the best power bank are important?
Let’s look at three points of portable charger’s characteristics that you should evaluate when choosing your “best power bank”
 Power Bank Capacity
 Output Port Amperage
 Power Bank Portability

Power Bank Capacity

This is the most important parameter when we choosing power bank. It shows us how much electrical charge can be stored and used for our smartphone or other device. When we take the conversion rate (about 80%) into consideration, a power bank battery with 3200mAh and a iPhone 6 plus battery with 2915mAh.
The formula is: 3200mAH * 0.8 / 2915mAH = 0.88 (approximately)
But it’s better to make sure that the capacity of your power bank battery at least as big as your smartphone’s and preferably double that number.

Output Port Amperage
In general the USB ports support an amperage between 0.5A and 2.4A. It’s better to make sure that the charging port’s amperage is at least 1A for smartphone and for charging tablets it should be rated at 2A. But now there is new technology called smart technology, it can identify your connected device and output suitable amperage for your phone or other devices, so that you can charge your device faster.

Power Bank Portability
Imagine that you want to go out now, but you are thinking about whether you should take your power bank with you, in case that your smartphone will run out later. But look at the power bank which is bigger than your hand. Do you want to put it in the bag? When choosing a best power bank, you should consider one which is small enough to avoid inconvenience.
