  • 【4-Digit High-Precision Display】0.001V / 0.001A High-Resolution Four-Digit Display — Simultaneously reads and controls voltage and current with laboratory-grade accuracy. The encoder knob allows for ultra-fine stepless adjustment — ideal for electronics repair, PCB testing, battery charging, and DIY projects.
  • 【4 Groups of Storage Memories】Save up to 4 custom voltage/current settings (e.g., 5V/2A, 12V/1A) and recall them with one click. Eliminates repetitive adjustments for frequent tasks, boosting efficiency in production lines, DIY projects, or daily lab use.
  • 【Precision Encoder Adjustment】Adopts a high-precision rotary encoder for smooth and accurate adjustment from 0 to 9 in sequence, allowing fine-tuning and quick setting of voltage and current parameters with better hand feel and higher efficiency than traditional buttons.
  • 【OVP & OCP Protection】Built-in Over-Voltage Protection (OVP) and Over-Current Protection (OCP) automatically cuts off output when values exceed safety limits. Safeguards your valuable devices (e.g., phones, circuit boards, sensors) from damage due to voltage/current surges.
  • 【Multiple Safety Guards】Includes short-circuit protection (instant shutdown on short circuits) and intelligent temperature control (auto-cooling or power reduction if overheated). Enjoy worry-free use with comprehensive safeguards against electrical hazards.
  • 【One-Click Output Lock】Prevent accidental changes to settings with the one-key lock function. Perfect for busy workbenches, shared labs, or mobile use—ensures stable power supply without misoperations that could ruin experiments or damage equipment.
  • 【USB & Type-C Dual Fast Charging】Equipped with USB-A and Type-C fast-charging ports (supports QC 3.0/PD protocols) to quickly charge smartphones, tablets, laptops, and other USB-C devices. Combines a professional DC power supply with a versatile charger for multi-scene use.
