How to choose outdoor power supply?

1. Capacity

The capacity of the outdoor power supply is the first indicator we need to consider when purchasing. Does that mean that the larger the capacity, the better? Of course not, it depends on the individual situation to choose.

500W to 600W outdoor power supply, battery capacity of about 500Wh to 600Wh, about 150,000 mAh, can supply power for 100W devices for about 4-5 hours, 300W devices such as rice cookers for about 1.7 hours, and mobile phones can be charged for more than 30 hours Second-rate.

1000W-1200W outdoor power supply, battery capacity of about 1000Wh, about 280,000 mAh, can supply power for 100W devices for about 7-8 hours, 300W devices for about 2-3 hours, and mobile phones can be charged more than 60 times.

1500-2200W outdoor power supply, battery capacity of about 2000Wh, about 550,000 mAh, can supply power for 100W devices for about 15 hours, 300W devices for about 5-6 hours, and mobile phones can be charged 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 fail to supply power normally.Power Converter 220 Quotes

3. Output interface

(1) AC output: 220VAC (double plug, three plug) output interface, with 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, Home appliances such as electric drills and electric brocades and common electric tools are used for power supply.

(2) DC output: The 12V5521DC output interface is an interface that effectively outputs a fixed voltage after changing the input voltage, and is usually used for 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 outdoor power supplies have launched 18W USB-A fast charging Output port and 60WPD 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 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 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.
