Power Banks are becoming more and more popular today as our gadgets or devices are becoming smarter and multifunctional tools in our daily lives, dedicated to various types of communication such as phone calls, text messages, emails and other tasks, and these smart devices (smartphones and tablets) need more to make them work properly and last all day, so Power Banks are all the rage, and they come in all shapes and sizes. But what are they for? We explore their potential, and how to choose the right one.

What is a Power Bank and what can they charge?

Miwon Power Banks consist of a special battery in a special housing with special circuitry for controlling power flow. They allow you to store electrical energy (bank it) and then use it to charge your mobile device (take it out of the bank.) Power Banks are becoming more and more popular as the batteries in our beloved phones, tablets and portable media players last longer than we use them every day. By keeping a spare battery nearby, you can charge your device while away from a wall outlet.

What types of mobile power are available?

There are three main types of Power Banks on the market today.

  1. Universal Power Banks. they come in a variety of sizes and configurations and can be customized to fit your device requirements and budget.

Solar Power Banks, which have photovoltaic panels that trickle charge the internal battery when placed in the sun. Solar charging is not fast, so they can usually be charged by cable as well.

  1. The third type of Power Bank is the old-fashioned battery phone case. While they are convenient, the device compatibility of this type of mobile power is very narrow and

How long will a Power Bank last?

There are two important factors to consider.

  1. The number of charge/discharge cycles the mobile power can reliably perform during its life cycle.
  2. How long the power supply can be kept when not in use.

The answer to the first point may vary depending on the mobile power model, internal components, and build quality. We try not to store mobile power supplies that have less than 500 charge cycles. This will allow you to charge your device from a mobile power source every day for 1.5 years before it starts to lose its ability to hold a charge for long periods of time. Better and more expensive mobile power supplies will last longer, while smaller and cheaper units may fall short depending on how they are handled. Mobile power units are not usually used every day, so they typically last more than 18 months in real-world usage patterns.

The second point depends on the quality of the controller circuitry and the battery. A good mobile power supply can hold a charge for 3 to 6 months with minimal loss. A lesser quality mobile power may struggle to retain a useful charge for 4 to 6 weeks. In this regard, you get what you pay for, and if you need a long-term emergency power supply, consider increasing your budget to make sure you don't get caught out. Most mobile power sources will slowly lose power over time, somewhat influenced by the environment and how they are handled. For example, leaving a mobile power source in a car where the temperature can fluctuate significantly over time can shorten its life.
