In this era of full of power anxiety, there was a time when everyone had a mobile power supply to meet the charging needs of a mobile phone for a day. However, with the emergence of more and more electronic devices, it seems that the mobile power supply can no longer meet our daily electricity needs. Therefore, the outdoor power supply that has been popular in foreign countries for a long time is slowly entering people's attention. However, among many outdoor power supply brands, choosing a good outdoor power supply can make us use electricity more safely and efficiently. So how to choose an outdoor power supply? Let's look down.
1. Capacity
The capacity of the 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, it can power 100W devices for about 4-5 hours, 300W devices such as rice cookers can supply power for about 1.7 hours, and mobile phones can be charged for more than 30 hours Second-rate.
1000W-1200W outdoor power supply, the battery capacity is about 1000Wh, about 280,000 mAh, it can supply power for 100W devices for about 7-8 hours, 300W devices for about 2-3 hours, and the mobile phone can be charged more than 60 times.
1500-2200W outdoor power supply, battery capacity of about 2000Wh, about 550,000 mAh, about 15 hours of power supply for 100W devices, about 5-6 hours for 300W devices, and mobile phones can be charged 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 the mains, the waveform is the same pure sine wave as the mains, can be used for fans, kettles, rice cookers, microwave ovens, refrigerators, Electric drills, electric picks and other household appliances and common electric appliances are used 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 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 more and more outdoor power supplies have launched 18W USB-A fast charging The output port and the USB-C output port of 60W PD fast charging, 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, then you can use the car Charging, or even charging with solar panels, put it on the roof to absorb solar energy, it can be fully charged in a few hours, and at night, you can use the electricity stored by the solar panels, 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. Let’s briefly talk about their advantages and disadvantages.
18650 lithium battery: It 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 compared with lithium iron phosphate. The battery will be short.
Lithium Iron Phosphate Battery: Long lifespan, higher safety performance, support for fast charging, wide working range, no heavy metals and rare metals, green and environmentally friendly.
