Ansmann 1001-0050 Indoor Battery Charger

The ANSMANN Indoor battery charger 1001-0050 is a compact, micro-USB powered charger for rechargeable Lithium‑Ion and NiMH cells. It accepts common cylindrical Li‑Ion sizes (including 26650, 22650, 18650, 18500, 17670, 16340, 14500) and AA/AAA NiMH batteries, and offers two independent charging slots that automatically detect the inserted cell and begin charging with correct polarity.

Advantages

This charger uses a microcontroller-controlled system to manage charging and prolong battery life by stopping charge when cells reach full capacity and applying maintenance charging for NiMH cells. It includes colour-coded LEDs above each slot for clear status indication and fault detection, supports charging from any standard 5V/1A USB adapter, and is compact and suitable for indoor use. The device is supplied with a Micro-USB cable and fits typical home charging needs.

Suitable for

• Recharging cylindrical Li‑Ion batteries (26650, 22650, 18650, 18500, 17670, 16340, 14500)
• Recharging NiMH AA and AAA cells
• Home or indoor use where a compact USB-powered charger is required
• Users who need to charge one or two batteries independently

How to use

Connect the charger to a suitable 5V USB power source using the supplied Micro-USB cable. Insert one or two rechargeable cells with the correct polarity into the slots; the charger detects the cell type and starts the charge cycle automatically. Monitor the colour-coded LED above each slot to check charging progress or to identify faulty cells. Once charging is complete the charger will stop charging the cell; NiMH cells receive maintenance charging after the main cycle if required.

Recommendations

For best results and shorter charge times use a 2.4A USB adapter with Smart IC as recommended by ANSMANN. Always follow manufacturer instructions for the specific battery type, avoid charging damaged cells, and use the charger indoors in a dry environment.
