Outdoor power supply, as the name suggests:
it is a power supply that can be used outdoors without electricity, and can output DC power (mainly 5V, 9V, 12V, 24V, USB-5V/9V, DC5211-12V, cigarette lighter -12V, PD-5V/9V/12V/24V) and alternating current (domestic 220V, foreign 110V and other voltage levels), with the development of digital electronic equipment, there are more and more electrical equipment. In addition, people who like outdoor camping, photography, outdoor work, special patient care ventilators, and emergency electricity also need such products.
For outdoor use, I chose an outdoor power supply without a fan to avoid the entry of dust and have the characteristics of dust protection. The circuit life of the power supply will be better, and it is also small in size and easy to carry. Secondly, the power level and battery capacity need to be selected according to your actual needs.
What is two-way charging:
Two-way charging, to put it bluntly, is an ordinary charging head or a charging head that supports fast charging that outputs 5v/9v/12v, which is connected to the charging port of the mobile power supply to charge the power bank. Charge. In this way, the power bank is charging and the mobile phone is also charging, which can improve the charging efficiency and reduce the charging time of the power bank.
Outdoor power supply dual input charging principle:
Input electrical energy and store it in advance in the form of chemical energy. When an external power supply can be found, pre-charge the built-in battery, that is, input electrical energy, and store it in the form of chemical energy in advance. When needed, the battery provides energy and generates electrical energy, and the voltage converter (DC-DC conversion) Device) to the required voltage, output from the output terminal (usually a USB interface) to supply the required equipment to provide power for charging or other purposes.
