1. Capacity and power advantages
· Larger capacity: The capacity of portable power stations is usually 100Wh to 2000Wh or even higher (1Wh≈0.278Ah, calculated at 5V voltage), which can meet the long-term power supply of high-power devices. For example, a 600Wh power station can power a projector with a rated power of 100W for about 6 hours.
· Higher power output: Supports multiple interfaces such as AC, DC, USB, etc., and can drive high-power devices such as rice cookers, electric drills, and drones (ordinary power banks can only charge low-power devices such as mobile phones and tablets).
2. Interface and functional diversity
· Multi-type interface: Common interfaces include 220V AC socket (adapted to household appliances), DC interface (such as car appliances), USB-A/C (fast charging mobile phones), Type-C (supporting PD protocol), etc., which can power multiple devices at the same time.
·Extended functions: Some models are equipped with solar charging ports, which can be charged by solar panels and are suitable for long-term outdoor use; some products also have functions such as wireless charging, emergency lighting, and SOS alarm.
3. Wider application scenarios
·Outdoor scenarios: Power coffee machines and ovens when camping, charge car refrigerators and car inverters when driving, and support the use of power tools when working in the field.
·Emergency scenarios: Used as a home backup power supply during power outages to power routers, lighting, and small household appliances; basic electricity needs during natural disasters (such as typhoons and earthquakes).
·Professional fields: Power cameras and fill lights for photography teams when shooting in the field, and provide stable power for testing equipment at the engineering site.
4. Power supply stability and battery life
·Stable output: Using lithium battery packs and voltage stabilization circuits, the voltage can be kept stable even if the power is reduced, avoiding damage to the equipment due to voltage fluctuations (the voltage of ordinary power banks may fluctuate slightly when the power is reduced).
·Long battery life and fast charging: Supports multiple charging methods such as AC power fast charging and solar charging. Some products can be fully charged in 1-2 hours; while ordinary power banks can only be charged through USB ports, and the larger the capacity, the longer the charging time.
V. Durability and safety
·Structural design: The outer shell is mostly made of fireproof materials, with shockproof, dustproof, and waterproof (some models) characteristics, suitable for complex outdoor environments; the interior is usually equipped with a BMS battery management system to prevent overcharging, over-discharging, and short circuit.
·Battery type: Mostly use automotive-grade lithium batteries (such as lithium iron phosphate), with longer cycle life (up to 1,000 times or more), while ordinary power banks mostly use 18650 or polymer lithium batteries, with a cycle life of about 500 times.
VI. Capacity display and management
·Accurate power display: The LCD screen displays the remaining power, output power, estimated usage time and other information in real time, which is convenient for users to plan power consumption (ordinary power banks mostly use LED lights to roughly display power).
·Intelligent management system: The power status can be remotely monitored and the output mode can be adjusted through the APP. Some products support multi-device linkage power supply.
