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
