BFKK Smart 3-in-1 Battery Charger with 12 AA & 12 AAA Batteries

SKU CH-3K2N-XEBB0

A 3-in-1 charger, tester and organiser holds 12 AA and 12 AAA rechargeable cells, auto-detects polarity, manages each battery individually and reports status via an app

  • Charges 12 AA and 12 AAA cells simultaneously
  • Polarity-free slots accept batteries in any orientation
  • Per-cell health check isolates faulty units automatically
  • App shows real-time charge level and cycle data
  • Temperature-aware current control protects battery lifespan

Smart 3-in-1 Charger System

This BFKK unit combines a charger, tester and organiser in a single station. It stores up to 12 AA and 12 AAA rechargeable cells, keeping them ready for use in homes, offices and institutional settings. The system accepts any brand of AA or AAA Ni-MH batteries plus BFKK Ecolast 1.5 V lithium AA cells.

Polarity-free operation suits mixed collections

Drop cells in any orientation without aligning positive or negative terminals. The per-cell management system checks each battery before charging, so only healthy cells receive current while incompatible or degraded ones are rejected. Buyers who need to charge C, D or 9 V formats, or who require simultaneous charging beyond the 12 AA and 12 AAA slots provided, should look at a different solution.

2100 mAh Ecolast lithium AA capacity

Each included Ecolast 1.5 V AA lithium battery delivers a 2100 mAh rating and carries a smart chip that syncs with the station for health monitoring, cycle count and charge status via the companion app. This capacity figure is the key metric for estimating runtime in high-drain devices.
