What is an Outdoor Battery Power Supply?

An outdoor battery power supply is a portable power generator that has various ports for charging devices. It can also be used as a backup power source in emergency situations. Its port types vary, but the mainstream ones mainly include USB, type-c, DC and car charger ports.

These devices are more eco-friendly than gas generators, and their lithium batteries require less maintenance. However, they can be a bit more expensive upfront.


The battery is the heart of any cordless tool. The amount of work a tool can do is limited by how much energy its battery pack can put out, and this energy comes from the number of electrons that flow through each point of the circuit at a given time, which is measured by current. The battery’s voltage and current are related: Voltage is the difference in concentration of positive ions at different points of the cell, and current is the number of electrons that pass through any one of these points.

To produce this flow of electrons, the battery has to have two electrodes. These are usually made of different metals and act as the battery’s anode and cathode, respectively. When the cell is charged, ions move from the anode to the cathode through the electrolyte solution. This creates electricity, and the more ions that move, the higher the voltage of the battery.

Typical lead acid batteries are flooded, meaning they have plates, separators and a liquid electrolyte that submerges the plates. They require regular outdoor battery power supply watering and can be damaged by extreme temperatures. The Jackery Explorer portable power station, on the other hand, uses lithium titanate batteries that are safe and long-lasting, with a high energy density. They are also quieter and more environmentally friendly than traditional gas-powered generators.


Whether for outdoor activities, travel or family emergencies, a convenient and portable power supply can be the best choice. It can provide electricity for a variety of equipment such as cameras, fill lights, projectors and kettles. It also provides backup power for your home electrical appliances.

The core of an outdoor battery power supply is the battery, which can be categorized into ternary lithium and lithium iron phosphate batteries. While ternary lithium has a good low-temperature performance and high charging efficiency, it is easy to decompose under high temperatures. Its service life is not as long as that of lithium iron phosphate, which has excellent cyclic properties and a longer lifespan.

Lithium iron phosphate is a popular battery for portable power supplies. It has a very good low-temperature performance and charging and discharging efficiency, and its service life is up to six years. It is also safe and environmentally friendly. It can be used in a wide range of applications, including outdoor photography, outdoor live broadcast and RV travel.

In addition, the battery in an outdoor power supply can be recharged through a solar panel and can be connected to a car charger. It is recommended to choose a power station that has a larger number of ports, a richer variety and a faster charging function. This way, more digital devices can be charged at the same time.

Power supply method

Outdoor battery power supply is a kind of portable energy storage power supply with built-in lithium batteries and an inverter to convert DC power into AC power. This power supply has a variety of charging methods, including solar panel charging, mains charging, and vehicle charging. It can also charge mobile devices and other digital equipment. It can be used in a variety of situations, such as outdoor shooting, mobile office, and camping.

It can also act as a backup power supply for household electrical appliances, preventing sudden blackouts during summer. Outdoor battery power supplies are generally light and compact, making them easy to carry. They are especially useful for photographers and other outdoor enthusiasts who need to work in remote locations with limited space or infrastructure.

In constant current mode, the power supply behaves like a current source and maintains a constant current regardless of load conditions. This is accomplished by varying the voltage in proportion to the current drawn from the battery based on Ohm’s law.

This method of power control is more efficient than traditional VMC. In contrast to the sawtooth- or triangle-signal output of a traditional voltage error amplifier, the peak current mode control (PCMC) provides a direct ramp waveform into the PWM-generation comparator. This allows the power supply to react quickly and accurately to changes in load.


When looking for a power supply, it’s important to consider how much energy you will need. The higher the capacity, the more power you will have for your equipment. Additionally, the more features the power supply has, the better. Some even include a display off grid solar power that tells you how much energy is left. It is also important to look for a high-quality build that can withstand the elements. This is especially important for those who plan to use their power supplies camping or overlanding.

A portable power supply is a lithium battery energy storage power supply that is used to charge electrical appliances. It consists of a voltage inverter, a lithium-ion battery and a BMS battery management system. The power supply can convert DC power into AC power for appliances and support multiple interfaces for charging digital devices. It is ideal for outdoor travel and emergency use.

The main function of a portable power supply is to provide emergency power supply for electronic equipment in the event of a sudden power failure. It can also act as an energy storage device in household settings to avoid frequent electricity consumption. It is also used as a power source for emergency vehicles during natural disasters.

Compared to ordinary lithium batteries, lifepo4 batteries are more durable and can be recharged many times without the risk of swelling and explosion. They can also withstand the impact of bumps and falls. Moreover, their service life can reach 6 years.
