VOLTCRAFT CB48AA Round Cell Charger for NiMH and Li-Ion AA Batteries (VC-17157045)

Photographers, field technicians, and gadget enthusiasts rely on AA batteries to power their equipment daily. The VOLTCRAFT CB48AA keeps those batteries ready with independent charging for up to four NiMH or Li-Ion AA cells. Each slot works separately, so you can mix battery types and charge one or more cells as needed without waiting for pairs.

Key specifications

• Charges 1–4 AA (Mignon) round cells
• Supports NiMH and Li-Ion battery chemistries
• Automatic battery type detection per slot
• Charging current: 500 mA per slot
• USB-C input: 5 V DC, 2 A
• LED status indicator for each slot (red = charging, green = done)
• Safety features: overcharge, short-circuit, reverse polarity protection, temperature monitoring
• Includes USB-C charging cable

Why choose it

Individual slot monitoring means you can charge a single battery or any combination of NiMH and Li-Ion cells simultaneously. The charger automatically detects the chemistry and applies the correct charging method: Delta-U with trickle charge for NiMH, and constant current/constant voltage for Li-Ion. Built-in temperature monitoring and multiple protection circuits ensure safe operation even during extended charging sessions.

Ideal use cases

• Keeping spare AA batteries ready for cameras, flashes, and audio recorders
• Charging batteries for wireless keyboards, mice, and game controllers
• Maintaining batteries for measurement instruments and sensors
• Portable use with a USB power bank or laptop USB-C port
