["Description:\n\nFeatures:\nbrand new and high quality\nBasic parameters:\nThe output voltage can be set to 5V/8V/9V/12V, the default is 12V.\nInput voltage range: 2.5V-5VOUT. The input voltage must be lower than the set output voltage.\nOutput capability: When inputiing 3.7V lithium battery, it can output 5V1A, 8V0.5A, 9V0.45A, 12V0.3A.\nWhen inputting at 5V, it can output 8V0.7A, 9V0.7A, 12V0.5A.\nWhen the default 12V output, the LED indicator consumes about 1mA.\nIf the indicator is turned off, the input current is ＜1mA at no load.\n\nVoltage setting description:\nThe front side of the PCB can be seen with the words A and B. Use the soldering iron to change the pad pass next to the charater.\nThe output voltage can be cahnged by breaking. In the following table, 0 indicates that the pad is disconnected, and 1 indicates that the pad is connected.\nThe pad next to the LED indicator can also be turned off to turn off the indicator.\nA B VOUT\n0 0 5V\n0 1 8V\n1 0 9V\n1 1 12V\n\nSpecification:\nColor: As pictures shown.\nSize: app. 22x11mm(0.87x0.43in)\nMaterial: Electronic component\nQuantity: 1 pc\n\nNote:\nTransition: 1cm=10mm=0.39inch\nWith retail package.\nPlease allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x Boost Module(other accessories demo in the picture is not included.)"]
