this digital voltmeter and ammeter tester?\u003c\/h4\u003e\n\u003cp\u003eA: The Gaqqee battery capacity tester is compatible with a wide range of USB and Type-C devices, including USB chargers, Type-C chargers, power banks, data cables, laptops, smartphones, and other DC-powered devices operating within DC 4.5–36V and 0–8A. Its automatic fast-charging protocol detection makes it suitable for virtually all modern charging standards.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use the tester overnight without damaging my device?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The built-in screen-off \/ sleep mode lets you briefly press the multifunction button to turn off the display while the device continues charging normally. This makes overnight charging both safe and energy-conscious without interrupting the charging session.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between the USB, Type-C, and USB + Type-C versions?\u003c\/h4\u003e\n\u003cp\u003eA: The USB-only version measures through a standard USB port; the Type-C version is optimised for USB-C devices; and the combined USB + Type-C version includes both ports simultaneously, where USB input maps to USB output and Type-C input maps to Type-C output. Choose based on the devices you most frequently test.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I reset the accumulated capacity data?\u003c\/h4\u003e\n\u003cp\u003eA: Rapidly triple-tap the multifunction button to reset the battery level (mWh) reading and clear the current group's timer back to 0.00. To switch cumulative data storage group numbers (NO.X), hold the button for 2 seconds.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
