What Is A Power Bank, And Why Always Have One Around?

Portable batteries are practical and save anyone when the cell phone “dies” earlier than expected. See exactly what a power bank is and why you need one.

Needing to call an app car, having an interrupted conversation, being unable to listen to music or watch videos, and even failing to respond to critical messages from contacts and contacts. Running out of battery throughout the day and not having an outlet nearby can be a problem; for these situations, the Power Bank saves a lot of people. 

What Is A Power Bank?

A power bank is a portable battery, so you can keep your cell phone active even after its battery runs out. Some models also work on tablets and GPS. Currently, there are three models of power banks: one that works through a USB cable, one that is attached to your cell phone, like a cover, and another that works with solar energy. 

USB Power Bank

This type of portable battery is quite common and easy to find. It can be charged via a USB cable and a charger or when connected to the notebook and the computer turned on; if you prefer, you can set it even when it is related to the. The good news regarding USB power banks is that they can be used independently of your cell phone. Remember that if your cell phone is from Apple, the connection will be made through Lightning, the brand’s connector. 

Another good increase in portable batteries over the last 3 to 4 years is the possibility of wireless charging; place your smartphone and other compatible devices on the power bank and let the magic happen as long as the power bank is charged.

Power Bank Attached To The Cell Phone

This type of power bank, when placed on the cell phone, is very similar to a protective cover. However, it makes the cell phone bigger, thicker and heavier (by the way, the greater the power bank’s energy capacity, the heavier it will be). However, there is an advantage to using it: you won’t have to carry two different devices in your hand, but only one. 

Power Bank By Solar Energy

The portable solar battery is the most robust type of device because it’s like you’re charging two cell phones simultaneously. As the name suggests, it is set using sunlight, which is transformed into energy, but there is a catch: the solar power bank also has USB charging so you can use it in winter.

How To Choose A Battery Power Bank?

One of the criteria you can use to choose your portable battery is the number of charging and discharging cycles it will support, that is, its useful life; it is evident that the more processes it does, the more expensive it will be. Another fundamental factor is to observe the number specified in milliampere-hours, or mAh, which must be at least the same capacity as your smartphone but preferably greater. At a time when smartphones have between 4,000 and 7,000 mAh, a 10,000 mAh power bank will be enough.

It is essential to remember that transferring the load from one device to another consumes an amount of energy. Therefore, some of it will be spent on this process. Also, see if your machine comes with the National Telecommunications Agency (ANATEL) seal. This ensures that it will comply with safety standards and not have problems such as short circuits and overload. 

Why Is A Power Bank Important?

• You will be able to keep your cell phone charged even on days when you forget the charger at home; 
• You will no longer need to borrow the charger from friends, acquaintances or family;
• You will be able to watch movies, series and videos quietly for longer; 
• You can use the portable battery on your cell phone and charge tablets, GPS and other devices.
