Keeppower I8 Battery Charger with 8 × 1.5V AA Li-ion Batteries 3133mAh

The Keeppower I8 is the ultimate all-in-one smart charger and battery kit, featuring 8 high-performance 1.5V AA Lithium-ion (Li-ion) rechargeable batteries. Compact and highly efficient, this set is ideal for travel, sports, outdoor activities, and demanding daily applications.

Constant 1.5V Output & Smart Low-Battery Warning

Thanks to integrated voltage-regulation technology, Keeppower P1450i3 batteries maintain a rock-solid 1.5V output for over 90% of their runtime. Only when the battery is nearly depleted does the voltage slowly decrease linearly from 1.5V to 1.1V. This ensures that sensitive devices receive a timely low battery warning instead of shutting down abruptly.

Key Highlights & Features

• Complete All-In-One Solution: Includes the 8-slot I8 smart charger and 8 premium Keeppower P1450i3 (3133 mAh) AA Li-ion batteries.

• Independent Slot Monitoring (MCU): Each charging channel is controlled individually with its own LED indicator (Red = charging, Green = fully charged).

• Universal USB-C Input: Future-proof Type-C input allows the charger to be powered easily via 5V USB adapters, power banks, or car chargers.

• Built-in Safety Circuit: The batteries feature an integrated protective circuit (BMS) against overcharging, deep discharge, over-current, and short circuits.
