How Does A Battery Pack for Phone Work? 

The working principle of a mobile phone battery pack is based on the charging and discharging of the battery, the storage, and the output of electrical energy. It usually contains one or more rechargeable batteries, such as a lithium-ion or lithium-polymer battery.

When the battery pack for the phone is connected to an external power source, electric energy flows into the battery inside the power supply through the charging line. At the same time, the electrical energy is converted into chemical energy and cured by an internal chemical reaction.

Phone battery packs have a battery management system, such as Jackery Portable Power Stations, that can monitor the battery status and take timely measures to ensure its safety and stability. Specifically, the composition and functions of phone battery packs are as follows.

Battery Cell: The battery cell is the critical part of the battery pack for the phone and is responsible for providing a steady stream of current, equivalent to a car's fuel tank. Battery cells convert electrical energy into chemical energy and store it. The most commonly used battery cells are ordinary and advanced lithium polymer batteries.

Circuit Board: The circuit board contains the promotion and charge management systems. The boost system is responsible for boosting the voltage of the battery cell to 5V to charge mobile phones, tablets, and other devices. The charge management system monitors the charging process, including pre-charge, constant voltage, and float charges.

Shell: The shell protects the cells and internal circuitry.


Working Principle


When the battery pack for the phone is low on power, users can recharge it by connecting the charger to be used again.


When users need to charge their phones, they can connect to the battery pack for the phone through the USB interface. In this case, the stored chemical energy is converted into electrical energy through internal circuits and converters to be delivered to charge electronic devices. The circuit and converter of the battery pack for the phone can manage and convert appropriate amounts of electrical energy to meet load voltage and current requirements.

What Are The Types of Battery Packs for Phones? 

The most important function of mobile phone batteries, also known as mobile power supply, is to charge mobile phones and other electronic devices.

Phone battery packs can be divided into different types based on functions such as battery cells, capacity, output port, charging method, etc.

types of battery packs for phones

Below are the standard battery pack types for phones and the products that suit different situations. You can choose different battery packs for your phone according to your needs.

Classified by Battery Cells  

Lithium-ion Battery Pack: The most commonly used is lithium-ion battery pack, whose battery cell is made of lithium-ion battery. The main features are safety and reliability, high charging efficiency, and long service life, but the weight and volume are relatively large.

Polymer Battery Pack: Compared with lithium-ion battery packs, polymer lithium-ion packs are more miniature and convenient. It mainly charges small electronic devices, such as Bluetooth headsets.

Classified by Capacity  

The battery pack's capacity for the phone measures how much power it stores. Battery packs for phones currently on the market can be divided into three levels: small, medium, and large, according to capacity.

The small battery pack for phones has a small capacity, is light and portable, is suitable for short-term use, and is ideal for powering small electronic devices such as Bluetooth headsets and mobile phones.

The medium battery pack for phones has a moderate capacity and is suitable for powering medium-power electronic devices such as laptops and car equipment.

The large battery pack for phones, like Jackery Portable Power Station, has a large capacity and is suitable for long-term use or charging high-power-consuming devices such as tablets.


Number of times a cell phone can be charged

7,500 mAh

The phone's small, pocket-friendly battery pack is usually enough to charge a smartphone one to three times.

7,500- 14,999 mAh

A medium battery pack for a phone in a jacket pocket is usually enough to charge a smartphone 4-5 times.

More than 15,000 mAh

Large battery pack for phone, usually enough to fully charge a smartphone five times or more.

Classified by Output Interface  

The type of output interface of the battery pack for a phone will also affect its scope of use. Currently, mobile power supplies on the market can be divided into two types: single-port output and multi-port output, according to the output interface.

The single-output battery pack for phones has only one output interface and is suitable for powering a single device. Moreover, the single-port output battery pack for phones has a small output current and is ideal for charging low-power devices like mobile phones.

The multi-output battery pack for phones has multiple output interfaces. It supports charging multiple devices simultaneously, making it suitable for charging high-power-consuming devices such as tablets.

Classified by Charging Method  

The charging method of the phone's battery pack is also an indicator of its classification. The battery pack for phones on the market can be divided into wired and wireless charging according to the charging method.

The wireless charging battery pack for phones can charge mobile phones and other devices without connecting cables. Place the electronic device on the battery pack for the phone to charge. It is convenient, easy to use, and does not have problems such as wire tangles or power outages. However, mobile phones and other devices need to support wireless charging technology.

The wired charging battery pack for phones needs to be connected to the device through a cable for charging, which has higher charging stability.

Solar Battery Pack  

Another ideal charging solution for phones is a solar battery pack. A solar panel converts sunshine into electricity, allowing you to charge portable devices or store solar energy in a power pack.

Thanks to efficiency improvements and cost reductions in solar cells, portable solar chargers for phones are a viable way to provide electricity outdoors. Unfold the solar charger and place it where the sun beams directly. Then, charge the unit outside and ensure no obstructions or shade in the path. You may position the charger so that the solar panel confronts the sun.

Environmental protection is always our top priority when we travel in the great outdoors. Unlike fossil fuels, solar battery packs, like Jackery Solar Generators and Jackery Portable Power Stations, don't generate any carbon emissions while generating energy. Wherever there is daylight, there is usable energy.
