Choosing a portable power station that suits oneself requires comprehensive consideration of multiple factors. Here are some key points:
Power demand:
Calculate the total power of the device: First, list the devices that need power supply, such as mobile phones, laptops, refrigerators, electric hotpot, etc., and check the rated power of each device. For some devices with high startup power, such as refrigerators, air conditioners, etc., the power demand during startup should be considered, and the startup power is usually 2-3 times the rated power.
Reserved power redundancy: To avoid long-term full load operation of portable power stations, it is recommended to choose models with rated power 20% -30% higher than the total power consumption.
Capacity size:
Short term use: If it is only used for a brief outdoor activity, such as a night's camping, to charge devices such as phones and cameras, a capacity of around 1000Wh is usually sufficient.
Long term use: If you need to use it outdoors for more than two days or need to power high-power devices such as projectors, fans, coffee machines, etc., it is recommended to choose a capacity of 1500Wh or more. If used as an emergency backup power source for home power outages, a capacity of 2000Wh or more will be more reliable.
Portability:
Weight and volume: If a single person needs to carry it, try to choose a portable power station weighing less than 10kg, or a design with wheels and handles for easy handling. If it is for car use, the weight limit can be relaxed appropriately, but the space size of the vehicle trunk should also be considered.
Fuel type: Lithium battery portable power station is lightweight, zero emission, ultra quiet, but relies on charging; Gasoline generators start quickly and have high power, but safety should be taken into account when storing fuel; Diesel generators have low fuel costs and long endurance, but their bodies are relatively heavy.
Output interface:
AC socket: When supplying power to high-power appliances such as rice cookers and electric kettles, AC sockets are essential to ensure that their quantity and power can meet the demand.
USB interface: including USB-A and USB-C interfaces, preferably with interfaces that support fast charging, such as a 100W Type-C interface, to quickly charge devices such as phones and computers.
Other interfaces: If there are specialized devices such as car refrigerators and light strips, corresponding car charging or DC interfaces are also required.
Battery type:
Lithium iron phosphate: It has the advantages of high safety, non ignition, and long cycle life, and is suitable for long-term use, especially in outdoor high-temperature environments.
Ternary lithium: Small in size and relatively low in price, but has poor stability at high temperatures and a relatively short battery life.
Charging speed:
Fast charging function: If you often need to use a portable power station, choosing a product with fast charging function can save charging time. Some high-end portable power stations can be fully charged within 1 hour.
Charging method: In addition to conventional mains charging, some portable power stations also support solar charging, vehicle charging, and other methods, increasing the flexibility of charging.
