Camping outdoors has become a popular way of travel. In order to meet the needs of outdoor travel, it is necessary to buy an outdoor mobile power supply. So how to choose a portable power station? You can choose from the aspects of capacity, power, output interface, charging method, etc. What is the best power of portable power station? Let's introduce the selection knowledge about portable power station, let's understand together.
1. What is the best power of portable power station
The output power of the portable power station is generally 300w, 500w, 1000w, 1500w, 2000w, etc. The higher the power, the more electronic equipment that can be powered, and the richer the content of outdoor activities. The power selection of the portable power station needs to be determined according to the power of the device used, the usage scenario, and the duration of use.
1. Outdoor short-term digital applications: Mobile phones, tablets, cameras, notebooks and other outdoor office photographers can choose products with a low power of 300-500w and a power of less than 1000wh (1 kilowatt-hour).
2. Long-term outdoor travel or self-driving travel: There are needs for boiling water, cooking, a lot of digital, night lighting, and audio entertainment. The recommended power is 1000-2000w, and the power is 2000wh-3000wh (2-3 kilowatt-hours). Products can meet the needs.
3. In case of home power outage emergency, in addition to lighting and digital power for mobile phones, it may also be necessary to drive household appliances. It is recommended to use 1000w, depending on the power of household appliances.
4. For outdoor work and construction work without mains power, it is recommended that the power be above 2000w, and the power should be above 2000wh. This configuration can basically meet the needs of general low-power operations.
2. How to choose portable power station
1. Capacity
The capacity of the portable power station is the first indicator we need to consider when purchasing. Is that the bigger the capacity the better? Of course not, it depends on individual circumstances.
The portable power station with 500W to 600W has a battery capacity of about 500Wh to 600Wh, which is about 150,000 mAh. It can power a 100W device for about 4-5 hours, a 300W device such as a rice cooker for about 1.7 hours, and a mobile phone can be charged for 30 hours. repeatedly.
1000W-1200W portable power station, the battery capacity is about 1000Wh, about 280,000 mAh, it can supply power for 100W equipment for about 7-8 hours, and 300W equipment for about 2-3 hours, and the mobile phone can be charged more than 60 times .
1500-2200W portable power station, the battery capacity is about 2000Wh, about 550,000 mAh, it can power a 100W device for about 15 hours, and a 300W device for about 5-6 hours, and the mobile phone can be charged more than 100-150 times .
2. Power
The power of the portable power station determines what kind of equipment can be used. For example, if you want to cook outdoors and use household appliances such as rice cookers, microwave ovens, refrigerators, and air conditioners, you need a portable power station with relatively high power, otherwise the power supply will trigger self-protection and cannot supply power normally.
3. Output interface
(1) AC output: 220V AC (double plug, three plug) output interface, has the compatibility comparable to the mains, the waveform is the same pure sine wave as the mains, can be used for electric fans, kettles, rice cookers, microwave ovens, refrigerators , Electric drills, electric picks and other household appliances and common electric tools for power supply.
(2) DC output: 12V 5521 DC output interface is an interface that effectively outputs a fixed voltage after changing the input voltage, usually used in notebook computers and tablet computers. In addition, there is a common 12V cigarette lighter port, which can provide power support for on-board equipment.
(3) USB output: fast charging is very important in this era when speed and efficiency are all important. Ordinary USB is 5V output, but now more and more portable power stations have launched 18W USB-A Fast charging output port and 60W PD fast charging USB-C output port, among which USB-A can charge electronic devices such as mobile phones, while USB-C can meet the power requirements of most office laptops.
4. Charging method
In terms of charging methods, the more the better, the most common is the mains charging, but when traveling outdoors, there is not often the opportunity to charge the mains, and the charging time is not short, so you can use the car Charging, even using solar panels to charge, put it on the roof to absorb solar energy, it can be fully charged in a few hours, and the electricity stored by the solar panels can be used at night, which is convenient, energy-saving and environmentally friendly.
5. Security
There are two types of portable power station batteries on the market, one is 18650 lithium battery and the other is lithium iron phosphate battery. The 18650 lithium battery is similar to the AA battery that is usually seen. It can be seen in all kinds of electronic products. It has good stability and compatibility, but the number of cycles is low, and its service life is slower than that of lithium iron phosphate batteries. short. The lithium iron phosphate battery has a long service life, higher safety performance, supports fast charging, has a wide working range, does not contain any heavy metals and rare metals, and is green and environmentally friendly.
