1. The best power for outdoor power
supply
The output power of outdoor power supply is generally 250w, 500w, 600w, 1000w, 1100w, 1800w, 2200w, etc. The higher the power , the more electronic devices that can be powered, the richer the content of outdoor activities. The power selection of outdoor power supply needs to be determined according to the power size of the equipment used, the usage scene, and the length of time of use.
1. Outdoor short-term digital applications: mobile phones, tablets, cameras, notebooks and other outdoor office photography crowds, choose products with low power 300-500w and power within 1000wh (1 kWh).
2. Outdoor long-term travel or self-driving travel: there are needs for boiling water, cooking, a lot of digital, night lighting, audio entertainment, the recommended power is 1000-2000w, and the power is 2000wh-3000wh (2-3 kWh). ) products can meet the needs.
3. In case of a power outage at home, in addition to lighting, mobile phone digital electricity, 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 operations and construction operations without mains power, it is recommended that the power should be above 2000w and the power should be above 2000wh. This configuration can basically meet the needs of general low-power operations.
Second, How to choose outdoor power supply
1. Capacity
The capacity of outdoor power supply is the first indicator that we need to consider when purchasing. Isn’t that the bigger the capacity, the better? Of course not, it depends on individual circumstances.
500W to 600W outdoor power supply, the battery capacity is about 500Wh to 600Wh, about 150,000 mAh, about 4-5 hours of power for 100W devices, and about 1.7 power for 300W devices such as rice cookers The phone can be charged more than 30 times per hour.
1000W-1200W outdoor power supply, the battery capacity is about 1000Wh, about 280,000 mAh, about 7-8 hours for 100W equipment, about 2-3 hours for 300W equipment, The phone can be charged more than 60 times.
1500-2200W outdoor power supply, the battery capacity is about 2000Wh, about 550,000 mAh, it can power 100W devices for about 15 hours, and 300W devices for about 5-6 hours, and the mobile phone can supply power for about 15 hours. Charge more than 100-150 times.
2. Power
The power of the outdoor power supply 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 relatively high power outdoor power supply. Otherwise, the power supply will trigger self-protection and cannot supply power normally.
3. Output interface
(1) AC output: 220V AC (double plug, triple plug) output interface, with compatibility comparable to commercial power , the waveform is the same pure sine wave as the mains, which can be used to power household appliances and common electric appliances such as fans, kettles, rice cookers, microwave ovens, refrigerators, electric drills, electric picks, etc.
(2) DC output: 12V 5521 DC output interface is an interface that effectively outputs a fixed voltage after converting the input voltage, usually used in notebook computers and tablet computers. In addition, there is also a common 12V cigarette lighter, which can provide power support for on-board equipment.
(3) USB output: fast charging is very important in this era when everything is about speed and efficiency. Ordinary USB is 5V output, but now there are more and more outdoor power supplies. Launched 18W USB-A fast charge output port and 60W PD fast charge 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 fact, the more charging methods, the better, the most common is the mains charging, but when traveling outdoors , It is not often possible to charge the mains, and the charging time is not short, then you can use the car to charge, or even use the solar panel to charge, put it on the roof to absorb the solar energy, and it can be fully charged in a few hours, and at night You can use the electricity stored by the solar panel, which is convenient, energy-saving and environmentally friendly.
5. Safety
There are two types of batteries for outdoor power supplies 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 various electronic products. The stability and compatibility are very good, but the number of cycles is low, and the service life is longer than that of lithium iron phosphate batteries. Shorter. The lithium iron phosphate battery has a long life, higher safety performance, supports fast charging, has a wide working range, does not contain any heavy metals and rare metals, and is environmentally friendly.
