Efest PRO C4 Smart Charger – Four-Bay Intelligent Charging with Battery Life Indicator

The Efest PRO C4 is a premium, four-slot universal battery charger tailored for vaping enthusiasts, flashlight users, and anyone who relies on rechargeable lithium-ion cells. Combining rugged build quality with smart charging technology, this unit provides dependable power management across a broad spectrum of battery sizes, with a strong focus on safety and prolonging cell lifespan.

Extensive Battery Support
The Efest PRO C4 accommodates a wide array of cylindrical lithium-ion batteries, covering nearly every common size on the market. It works seamlessly with: 10440, 14500, 14650, 16340, 16650, 17650, 17670, 18350, 18490, 18500, 18650, 22650, 26500, and 26650. Whether you're charging small 10440 cells for compact devices or high-capacity 26650 batteries for powerful mods, the PRO C4 handles them all without difficulty.

Four Independent Charging Channels
Each of the four bays operates on its own, letting you charge different battery types and sizes simultaneously with no cross-talk. The charger supplies a consistent 1A (1000mA ±10%) constant current (CC) per channel, delivering efficient and balanced charging. Unlike budget chargers that reduce current when multiple cells are inserted, the Efest PRO C4 keeps a full 1A available for every slot, significantly cutting down total charge time.

Battery Life LED Indicator System
A key highlight is the integrated Battery Life LED Indicator Light. This clever system goes beyond showing charge level—it assesses the overall health of your battery. By examining internal resistance and voltage behavior during the charging cycle, the LED indicator provides a clear visual readout of your battery's remaining useful life. This makes it easy to spot aging cells that may need replacement, boosting both safety and performance.

Thoughtful Design with Non-Slip Mat
The charger features a rugged, heat-resistant exterior with a built-in non-slip mat on the underside. This keeps the unit securely in place on any flat surface, preventing accidental sliding or tipping when inserting or removing batteries. The spring-loaded sliding contacts adjust to fit different battery lengths snugly, ensuring a reliable electrical connection every time.

Global AC Input and DC Output
The Efest PRO C4 is designed for international use, accepting AC input from 100–240V at 50/60Hz. This allows you to use it anywhere without a voltage adapter. The supplied power adapter outputs 12V DC at 1A, which is safer and more stable than direct AC-to-bay systems, as it keeps high-voltage conversion outside the charger itself.

Safety and Performance Features
With protection against over-current, over-voltage, short-circuits, and reverse polarity, the PRO C4 delivers worry-free operation. The 1A constant current strikes an ideal balance between charging speed and cell longevity, making this charger perfect for everyday use. If you want a dependable, bay-independent charger with built-in battery health diagnostics, the Efest PRO C4 is a wise investment.
