Portable lithium-ion battery energy storage power supplies (PES), also known as portable energy storage power supplies or outdoor power supplies, typically refer to backup or emergency power supplies weighing no more than 18kg. They use lithium-ion batteries as energy storage components and accept AC or DC input charging (e.g., AC 220V, vehicle 12V, etc.), with outputs of AC or DC (e.g., AC 220V, DC 12V, DC 5V, etc.).
Portable energy storage power supplies are safe, portable, stable, and environmentally friendly energy storage systems, also known as portable mobile power banks. They feature the following characteristics:
1. Lightweight and portable design for easy transport; overload/overcurrent/overdischarge/overcharge protection;
2. Imported high-strength engineering plastics, drop-resistant, shock-resistant, fire-resistant, and rainproof;
3. Large-capacity lithium battery pack, small size and light weight;
4. High-power pure sine wave output;
5. Unique overvoltage, overload, and short-circuit protection design;
6. Unique protective wall design;
7. AC 220V/110V pure sine wave output.
Most portable energy storage power supplies use lithium batteries as their energy source. Due to their lightweight, high capacity, and high power, portable energy storage power supplies are widely used in various fields, such as travel, leisure, and in cars and boats, serving as DC or AC power sources.
