An energy storage system is a system that converts electrical energy into other forms and stores it, then converts the stored energy into electrical energy when needed. Common forms of energy storage include chemical energy (such as batteries), mechanical energy (such as springs, flywheels), thermal energy (such as hot water storage), electromagnetic energy (such as capacitance, inductance), etc.

Energy storage systems are used in a variety of applications, including:
• Balance the supply and demand of the power grid, store the peak and valley load differences, and meet the electricity demand during peak periods.
• Off-grid generation, smoothing the volatility of renewable energy sources to meet changing electricity demand.
• Home or business use to reduce energy costs and improve power quality.
• Electric vehicles to improve the range and charging efficiency of electric vehicles.

• Improve the reliability and stability of electricity, making energy supply more stable.
• Balance differences between electrical loads and supplies to increase energy efficiency.
• Provide reliable power supply to remote areas in an off-grid environment.
• Reduce energy costs and improve energy efficiency.

• The cost of energy storage system is relatively high, and construction requires a lot of investment.
• Different energy storage technologies have different energy densities and efficiencies, and appropriate technologies need to be selected according to actual conditions.
• Some energy storage technologies have environmental and safety issues that require proper planning and management.
At present, our products have solved most of the problems existing in energy storage systems.

Common energy storage technologies include:
• Battery energy storage technology: such as lithium-ion batteries, lead-acid batteries, nickel-metal hydride batteries, etc.
• Mechanical energy storage technology: such as flywheel energy storage, spring energy storage, compressed air energy storage, etc.
• Thermal energy storage technology: such as hot water storage, heat accumulator storage, etc.
• Capacitive energy storage technology: such as supercapacitors.

A portable outdoor power supply is a device that stores electrical energy in a rechargeable battery and provides power through AC outlets, USB ports, or other outlets for various electronic devices when you’re outdoors or in remote locations.

Portable outdoor power supplies are used in a wide range of applications, including:

Camping or hiking trips to power lights, mobile phones, and other electronics.
Emergency situations where access to a power grid is limited or unavailable.
Outdoor events or concerts where access to power is limited.
Tailgating or outdoor parties to power speakers, grills, and other equipment.


Portable and easy to carry.
Provide power for electronic devices in remote locations or during power outages.
Can be charged by a variety of sources, including solar panels, car chargers, or AC outlets.
Can provide power for a variety of devices simultaneously.
