I. Cost-effectiveness analysis
Purchase cost
·Portable power station: Usually the purchase cost is low, and the price range is wide, ranging from a few hundred yuan to a few thousand yuan, which can be selected according to personal needs and budget.
·Traditional backup power supply: The price of generators varies greatly depending on the power and brand. Generally, the price of household generators ranges from a few thousand yuan to tens of thousands of yuan; the price of lead-acid batteries is relatively low, but the cost of large-capacity, high-quality lead-acid batteries cannot be ignored.
Use cost
·Portable power station: The use cost is low, mainly electricity costs, and the charging efficiency is high, and the power conversion efficiency can reach more than 90%.
·Traditional backup power supply: The use cost of generators is high, and they need to be driven by fuel (gasoline, diesel), and the fuel needs to be properly stored; although the use cost of lead-acid batteries is low, they need regular maintenance, and there is a memory effect, which affects the service life.
Maintenance cost
·Portable power station: Low maintenance cost, basically no special maintenance is required, only regular inspection and cleaning are required.
·Traditional backup power supply: Generator maintenance is complex and requires regular maintenance, oil and filter replacement, etc.; lead-acid batteries need to regularly add distilled water and adjust the electrolyte level, etc.
Service life
·Portable power station: Long service life, the number of charge and discharge cycles can reach more than 2,000 times, and if properly maintained, the service life can reach more than 5 years.
·Traditional backup power supply: The service life of the generator is affected by factors such as fuel quality and frequency of use; the number of charge and discharge times of lead-acid batteries is generally around 350 times, and no more than 500 times.
2. Advantageous application scenarios
Outdoor activities
·Camping, hiking, mountaineering: Portable power stations are small in size, light in weight, easy to carry, suitable for outdoor carrying, and provide power support for cameras, drones, mobile phones and other equipment.
·Self-driving tour: When resting or camping in the car, the portable power station can provide power for the vehicle's electrical appliances, increasing the convenience and comfort of travel.
Emergency backup
·Home emergency: In emergency situations such as power outages or natural disasters, portable power stations can be used as emergency backup power supplies to provide power support for lighting, communication equipment, etc.
·Office space: When there is a power outage in the office, the portable power station can power computers, printers and other equipment to ensure work continuity.
