A good power bank can help us more.  If your mobile phone runs out of power and you don’t have a portable charger, you are cut off. It means that you cannot make a contact with anyone during an emergency situation. So it is a necessity that you have a power bank with which you can charge your device on the spot.

When buying a power bank you will try to choose the best one. So how to choose a good power bank


The main attribute associated to a power bank is its capacity. We often cannot calculate how many times a specific power bank can charge our device. But the easiest way is based on mAh rating. More mAh rating means more capacity.

If you have a mobile phone with 1500mAh battery,a capacity of 1500mAh power bank can fully charge it once.

There are some sample usage guide1500mAh battery can be charged once by 1500mAh power bank. If you want to be charged by twice 5200mAh is the best choice and by four times 10000mAh will be the best choice. So what kind of capacities do you need it is according to your requirments. Suitable is the best!


One of the main reasons why you need to buy a power bank is the portability. The ability to charge your devices while on the move because you can simply take charger. If you have a long trip without a power bank, you cannot use the google map with your mobile. Or your car charger stopped working. You have to find your way back home. What should you do? Asking people for direction multiple times, it is so bad experience. At that time you will be aware of how important to own a portable power bank.


Be careful with the inexpensive power banks with big capacity. Many times you get what you pay for. Before buying, please do more research about it. I do not recommend the cheapest option. This is one of times where you indeed get what you pay for. A mid-rage to upper range price will be a great option with no sacrifice on quality.


Quality is so important. Because products with bad quality will hurt people’s health.Protection function is the first thing that we should focus on. Such as, overcurrent, overvoltage, overtemperature protection. Due to unknown causes overcurrent, overvoltage short circuit ,the  power bank can ensure safe of mobile phones and other digital devices through the internal protection circuit. Built in temperature senses chip .when the temperature of chip exceeds the default temperature, circuit close. So as to, effectively protect the portable power and rechargeable battery safety.
