Keeppower I4 Charger with 4 x 1.5V AA Lithium-ion Batteries (4300 mWh) – USB-C Input

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

The pocket size makes it 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 feature.

The battery remains stable at 1.5V for over 90% of its runtime only then does the voltage slowly drop linearly from 1.5V to 1.1V. This ensures devices receive a timely Low-Battery warning for maximum safety and reliability in continuous operation.

The Keeppower I4 charger features intelligent single-slot monitoring and an LED indicator.

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

This is a modern charger set with a USB-C connection, convincing with high efficiency, intelligent control, and a future-proof design.

Key Highlights:

• 4x 1.5V AA batteries (P1450I2, 4300 mWh) included in the set.

• Constant 1.5 Volt output voltage – even when the charge is low.

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

• LED charging indicator per slot.

• Individual monitoring of each cell for maximum safety.

Ideal for demanding consumers: Thanks to the integrated voltage regulation, the Keeppower P1450i2 batteries deliver a constant 1.5V, even with low residual charge.

The integrated protection against deep discharge, overcharge, and short circuit makes this set particularly safe and durable.
