Keeppower I4 Charger with 4 x 1.5V AA Lithium-ion batteries (3600 mWh) – USB-C Input

This is the perfect All-in-One set: Charger including 4 powerful 1.5V AA Li-Ion batteries.

Pocket-sized, ideal for travel, sports, outdoor use, and daily applications.

The Keeppower 1.5V Li-Ion battery delivers a constantly high operating voltage and is ideally suited for high-performance devices with a low battery warning indicator.

Due to the constant 1.5V voltage, the battery remains stable for over 90% of the runtime only after that does it slowly drop linearly from 1.5V to 1.1V.

This ensures that devices receive a timely Low-Battery warning – for maximum safety and reliability in continuous use.

The Keeppower I4 charger features intelligent individual bay monitoring and an LED indicator.

The set includes four 1.5V AA Li-Ion batteries with constant voltage and protection circuitry – ideal for devices with high energy requirements and sensitive electronics.

Key Highlights:

4x 1.5V AA batteries (P1450I, 3600 mWh) included in the set.

Constant 1.5 Volt output voltage – even as the charge decreases.

USB-C input on the charger – universal and future-proof.

LED charging indicator per slot.

Individual monitoring of each cell for maximum safety.

Batteries feature integrated protection against deep discharge, overcharge, and short circuit.
