Used as a USB based boosted power supply with protections for overvoltage, overcurrent, over power, over temperature, and undervoltage. Provides reliable power boosting and measurement capabilities for lab research, electronics projects, or educational demonstrations. Suitable for electronics enthusiasts, engineers, and students; ideal for anyone involved in detailed electronic work or education. The USB voltages regulator offers accuracy digital displays, providing exact readings for voltage, current, and frequency. Use scenarios: In a research lab to power experiments that require stable voltage and real time monitoring of current and voltage. In a DIY electronics project to supply higher current to prototypes while observing performance with digital readouts. In a classroom demonstration to illustrate power regulation concepts with live voltage, current, and frequency readings.
