The capacity of a power bank is usually determined by the number of charges it can provide for a device in a single charge. For instance, a power bank with a capacity of 10000mAh will have enough power to charge a gadget up to 10000mAh.
• Multi-functional power banks: Multi-functional power banks are power banks with extra features like LED lights, digital displays, and built-in flashlights.

Functions and Features

The best power banks have features that enhance their performance and user experience. Here are some of them:

• Battery capacity: The capacity determines how much energy the power bank can store. It's generally measured in milliamp hours (mAH) or watt-hours (Wh). Higher capacity means the power bank can charge devices more times or provide a higher total charge before needing to be recharged itself. Most power banks' capacity ranges from 5,000 mAH to 50,000 mAH.
• Output ports: Power banks usually have one or more output ports to which devices can be connected for charging. The number of ports varies depending on the model. Some only have one port, while others have multiple ports so that several devices can be charged simultaneously. The type of ports also varies among different models. Many power banks come with USB-A and USB-C ports, but some may also include proprietary ports for specific devices or standards like USB Power Delivery.
• Power output: This refers to how fast the power bank can charge devices, measured in watts (W). Based on the wattage, different power banks will charge devices at varying speeds. A higher power output means the power bank will charge compatible devices faster.
• Charging methods: Many power banks can be recharged through USB by connecting them directly to a wall plug, computer, or another power source. Some models also feature ways of recharging themselves that allow them to stay charged without needing an external power source, e.g., solar charging.
• Size and weight: When looking to buy a power bank for wholesale, firm or retail buyers should consider the power bank's physical size and weight. More compact models are more portable and lightweight, so they're better suited for travel or using on the go.
• Build quality: The materials used to make a power bank can affect its durability and dependability. Buyers should look at the quality of the different parts, such as the housing, ports, and connectors, to ensure it won't break down after only a few uses.
• Additional features: Depending on the model, some power banks may include extra features beyond just being able to charge devices. For instance, some have built-in torches/flashlights, charging indicator lights, emergency flashlight functions, or integrated cables that connect directly to devices for simultaneous wired connection and charging without having to purchase additional separate connecting cables.

Applications of Power Banks

Applications of power banks span across numerous industries. The finance and banking industry employs power banks in cash transit. Armed security agencies use them to secure cash transit. The power banks serve as a means of charge to different kinds of electronic devices and aids of communication during lengthy and sometimes risky transit.

Co-working facilities also use power banks for their services. Workers in different industries and of different ages visit such facilities. An accessible and chargeable source of power aids the uninterrupted working of employees and visitors. Power banks are also important for the hospitality industry, especially in areas like airports and hotels. Airports have charging stations where power banks can be plugged in to aid electronic devices. Long waits in airports sometimes extend to hours. Travellers often use power banks to charge their electronic devices, particularly in areas without charging stations.

Trade shows and events also use power banks. Target audience and potential customers are often offered free power banks, which helps brand awareness and power these devices throughout the event. Retail stores also employ the use of power banks to charge electronic devices like tablets, point of sale machines, and mobile phones. The electronics industry is also an important user of power banks. They are used in the production of power banks, and major electronic distribution stores sell them.

Medical facilities depend on power banks to charge electronic devices like phones, tablets, laptops, and other medical aids that require a secure and portable source of power. Some hospitals have power banks on hand to charge electronic equipment in the event of a power failure. Schools also provide power banks to charge different electronic devices like laptops and tablets, especially in areas where charging stations are not available. They serve as a distraction for students and a source of power for teachers' electronic devices.

Employers of different industries across the globe use power banks as a means to promote employee welfare and retention.

How to choose a power bank?

Prior to buying a power bank in bulk, it is essential to assess the target market and determine the kind of power banks that relate to clients' necessities. Additionally, consider the number of power banks to buy based on the storage capacity because it will determine the pricing and more features. Other factors to consider when choosing a power bank incorporate;

• Capacity: The capacity of a power bank indicates the total battery in the cell through the available storage. Thus, a higher battery capacity means it holds more power and can charge devices more in total. However, the charging efficiency will depend on the device's power and several factors that affect the charging process. In shorter terms, 1 watt hour equals 1,000 mAh. Therefore, using this equation can help determine the right power bank by multiplying Wh by the output voltage of 5 volts.
• Quality of cells: The type and quality of cells in a power bank charge the devices exceptionally well. Lithium-ion and lithium-polymer are popular battery types. Lithium- polymer power banks are more premium, lightweight, and compact than lithium-ion power banks. They also have a lower risk of swelling when charging devices and tend to last longer. On the other hand, lithium-ion power banks are affordable and commonly used. They are also known to have a higher energy density and hold more power.
• Construct and design: The power bank's quality, build, and design are crucial in determining its life span and ease of use. A well-designed power bank constructed with durable materials is less likely to break from bumps or drops. In addition to this, look for power banks with LED indicators, which are handy in displaying the charging status and remaining battery.
