How Power Banks Work and Are Used

How many times has your phone died while you were out and about? It is a frustrating experience, especially if you're in the middle of an important conversation or traveling. 

A power bank is a portable device that stores electrical energy in a rechargeable battery and provides power to electronic devices. It usually consists of a rectangular block with one or more USB ports, an LED battery indicator lights, and an input for charging the battery. Power banks come in all shapes and sizes and can be used to charge phones, tablets, laptops, cameras, and other electronic devices. 

To better understand the use of power banks, we will discuss how it works and provide some tips on choosing the right one for your needs.

WHAT IS A POWER BANK, AND WHAT DOES IT DO?

A power bank is a small, portable charger that can power up your smartphone, tablet, or other USB-charged devices when you're away from an outlet. Power banks are becoming an increasingly popular option for people on the go that serve as portable power stations for gadgets. There’s no need to worry about your devices running out of juice, even if you're in the middle of nowhere.

Most power banks use lithium-ion batteries, which are the same type of batteries used in many electronic devices. These batteries can hold a charge for days, so you can always be sure you have a backup power source when you need it.

Power banks work by storing energy in their batteries, which charge electronic devices. When the power bank connects to a device, it will begin transferring its stored energy to the device. Power banks typically use USB ports to connect to devices, though some may also have wireless charging capabilities.

DIFFERENT TYPES OF POWER BANKS

Portable Power Banks

These power banks are designed to be used as portable power stations and are easy to carry around. They usually have a small form factor and can fit easily in a pocket or bag. Many portable power banks also come with built-in or shorten cables, so you don’t have to worry about carrying extra cords.

High Capacity Power Banks

If you need a lot of charge for your devices, then a high-capacity power bank is likely the way to go. These power banks typically have 20,000mAh or more power like our Sherpa 100PD (25,600mAh), enough to charge most smartphones several times over fully. Many high-capacity power banks also come with multiple USB ports and USB-C Power Delivery ports so that you can charge multiple devices simultaneously.

Wireless Power Banks

Wireless power banks are becoming increasingly popular as more devices support wireless charging. These power banks allow you to charge your devices without plugging them in. Just place your device on top of the power bank, and it will start charging. 

CHOOSING THE RIGHT POWER BANK FOR YOUR NEEDS

Phones have become an integral part of everyday life for everything from entertainment to navigation. The popularity of the power bank only continues to increase to meet these needs.

However, with so many different types and brands of power banks on the market, how can you know which one is right for you? There's a few things to keep in mind when choosing a power bank:

Capacity

One of the most important factors to consider when choosing a power bank is capacity. It is measured in milliamp-hours (mAh) and will determine how much charge the power bank can hold. A lower-capacity power bank will suffice if you only need to charge your phone once or twice. However, you’ll need a higher-capacity power bank if you need to charge your phone multiple times or use the power bank to charge other devices, such as a tablet.

Output

Another essential factor to consider is output. It is measured in volts (V) and will determine how quickly the power bank can charge your devices. Most phones and tablets will charge with a 5V output, and the higher amperage will impact the speed at which they can recharge. Some newer devices can now recharge via USB-C power delivery this allows for a high voltage and amperage for faster recharge times.

Connectors

Most power banks come with one or more USB ports that you can use to charge your devices. However, not all USB ports are created equal. Some power banks have standard USB ports that can be used with any device, while others are beginning to switch to USB-C power delivery for faster recharges
