Apex Gear VCP4/R4 Smart Charger and Capacity Tester for Lithium Batteries: Automatically recognizes USB DC 5V and QC
For the DIY enthusiast or hobbyist who needs reliable power for flashlights, vapes, or electronics projects, this smart charger and capacity tester handles your 18650, 21700, and other lithium batteries with precision. While most chargers just power up cells, this device focuses on battery health—giving you confidence that your batteries are safe and performing optimally.
The digital screen shows real-time data for each channel, so you can monitor charging progress at a glance. It automatically recognizes battery types and adjusts settings, preventing overcharging. In capacity analysis mode, it tests how much power your batteries actually hold, helping you identify weak cells before they fail in use. The two-way Type-C and DC inputs offer flexible power options, whether you're at your workbench or on the go.
