Toviyon's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • 【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.
