In the fast-paced modern life, portable power stations have become our indispensable energy partners. Whether for outdoor adventures, 緊急事態, or daily home life, a high-quality portable power station can provide you with stable and reliable power support. This article will provide you with a detailed purchasing guide to help you select the most suitable portable power station for your needs.
Determine the purpose and requirements
まず最初に, clarify the main purpose for purchasing a portable power station. Is it for outdoor activities such as camping or fishing, as a backup power source for home power outages, or to support professional equipment like medical devices? Different purposes have different requirements for the station’s capacity, output power, and compatibility.

Determine the Power Station’s Capacity
How to Calculate the Required Battery Capacity Based on Your Electricity Consumption
The capacity of a power station is typically measured in watt-hours (うーん), which determines how much energy the station can provide. If you are only powering small devices such as smartphones and flashlights, a smaller capacity (例えば, 150うーん) might be sufficient. しかし, if you need to power household appliances or outdoor equipment, you may require a power station with a larger capacity, のような 4000 to 5000Wh.
Due to power conversion losses and the initial high current draw when devices start up, the actual required battery capacity is usually higher than the theoretical calculation. It is recommended to add a safety margin of 20%-30%:
Required Battery Capacity (うーん) = Total Daily Electricity Demand (うーん) × (1 + Safety Margin)
Consider Output Power
Output power, measured in watts (W), determines the types of devices that a power station can support. 例えば, some power stations may only be capable of powering low-power devices, while others with a higher power output can support large appliances, such as refrigerators or power tools.
Essential Appliances:
- 冷蔵庫: 400-800W (startup); 100-250W (running)
- ラップトップ: 40-300W
- Smartphones/tablets: 10-100W
- LED lights: 5-15W per bulb
- Wi-Fi router: 10-20W
Higher-Power Devices:
- Air conditioner: 500-3500W
- Hair dryer: 1200-1800W
- Electric kettle: 1200-1500W
- Space heater: 1000-1500W
- Microwave: 600-1500W

Portable Power Stations Cost Analysis
When analyzing the component costs of portable power stations, we need to consider several key elements that contribute to the overall price. Here’s a breakdown based on the latest data:
| Parts | Picture | Explanation | Proportion |
| Battery Cells |
 |
The battery cells are the most significant cost component in a portable power station, often accounting for the majority of the system's price.Lithium-ion batteries are commonly used due to their high energy density and lack of memory effect. The cost of these batteries has been decreasing, making portable power stations more affordable. | 60% |
| Battery Management System (BMS) |
 |
The BMS is essential for managing the charging and discharging process of the battery, ensuring safety and longevity. The system adds cost but is essential for the reliable operation of the power station. | 10% |
| Inverters |
 |
Inverters convert the direct current (直流) from the batteries to alternating current (交流), which is used by most household appliances. The cost of inverters can vary based on their capacity and efficiency. | 10% |
