through EBC-A10H. The output current can reach: 5V 3A. After actual testing, when Pi4 runs the official Raspbian system, the normal power consumption is about 5V 1A. When peripherals such as a camera and U disk are inserted, the power consumption gradually increases to 5V 2A. Therefore, the use of UPS v3 to supply power to Pi4 has a large margin. And in the case of output 3A. The 2.54 pin header can also guarantee power supply above 5V. Users need to note that 5V and GND must use silica gel DuPont wires. If the ordinary DuPont line is used, when the current is large, it will cause a large line loss, so that the low voltage symbol of lightning can be observed on the Pi4 screen.\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0084\/7465\/6845\/files\/UPSPack_V3P.jpg?v=1631849661\" alt=\"\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0084\/7465\/6845\/files\/UPSPack_V3P.jpg?v=1631849661\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0084\/7465\/6845\/files\/UPSPack_V3P.gif?v=1631849705\" alt=\"\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0084\/7465\/6845\/files\/UPSPack_V3P.gif?v=1631849705\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e2) Battery life\u003cbr\u003eUPS V3 V3P onboard battery interface is PH 2.0 package (compatible with old UPS motherboards), and the positive and negative signs are printed on the PCB board.

The demand for external power adapter is 5V 2A-5V 3A. There is a power path management system inside the UPS, which automatically adjusts the input current. For example: when there is no external load or the load is light, and the onboard battery of the UPS is fully charged. The input current will be approximately equal to the current consumption of the load. The TYPC-C input charging cable should be as short and thick as possible, so that the line loss is small, so that the charging power to the UPS motherboard is sufficient.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eTip: If the nominal parameter of the power head is 5V 3A and the UPS is working while charging and discharging, the battery power is still decreasing. The reason may be that the input TYPE-C line loss is large (or the power head parameters are imaginary). It is caused by the fact that the power of the actual power adapter reaching the TYPE-C interface is not enough to supply power to the load and charge the battery at the same time.
