Technical Specifications

Why This Set Is Practical

The imuto TF-CD-056CE set is designed as a compact rechargeable power solution for users who do not need the larger 8-battery set but still want the same key benefits: constant 1.5V output, lithium performance, fast Type-C charging, and safe organized storage. It is especially useful as a starter kit for homes, offices, repair benches, smart devices, and travel bags.

Why Constant 1.5V Output Matters

Many rechargeable AA batteries provide around 1.2V, which may cause some devices to show low battery early or operate with weaker performance. imuto rechargeable AA lithium batteries are designed to maintain a regulated 1.5V output, helping compatible devices work more consistently across the battery cycle.

4-Slot Charging Case Details

• Charges 1 to 4 compatible imuto AA lithium batteries as needed.
• Fully charges the set in about 3 hours with a suitable 5V/2A adapter.
• USB Type-C input makes the charger easy to power from common USB sources.
• Independent slots allow flexible charging without waiting for all batteries to be empty.
• Works as a battery storage case for better organization and protection.
• LED indicators help show charging and battery status during operation.
• Compact design makes it suitable for daily use, storage, and travel.

Recommended Uses

• Video doorbells and security cameras.
