8-Slot 18650 Li-ion Smart Battery Charger 220V Input Independent Multi-Channel Charger for Rechargeable Cells

Overview

Eliminate charging bottlenecks with our heavy-duty 8-Slot 18650 Lithium-Ion Smart Battery Charger. Designed for high-volume users, this desktop charging hub accepts a direct 220V AC domestic wall input to deliver fast, stable power across eight completely isolated charging channels. Each individual slot utilizes an independent micro-controller unit (MCU) that automatically detects the inserted batterys chemistry and capacity, applying the optimal charging current without risk of cross-channel interference or overcharging.

Key Features

• 8 Fully Independent Slots: Charge a single battery or all eight at once. Each slot monitors and stops charging individually once full.

• Direct 220V Power Input: Built-in power management circuit plugs straight into a standard Pakistani wall outlet without needing bulky external power bricks.

• Multi-Layer Safety System: Equipped with short-circuit defense, reverse-polarity protection (if a battery is put in backward), and real-time temperature control to prevent overheating.

• Universal Li-ion Compatibility: While optimized for flat-top and button-top 18650 cells, the spring-loaded slider slots also accommodate 14500, 16340, 18490, and 26650 Lithium batteries.

• LED Status Indicators: Simple, color-coded LEDs over each slot instantly display the real-time status (Red: Charging / Green: Fully Charged).
