Kastar LI-42B twin pack and triple USB charger

This set supplies two lithium-ion batteries rated at 1400 mAh and 3.7 V each, plus a charger that can replenish three cells simultaneously. It targets owners of compatible Panasonic handsets who need ready spares for cordless phones or DECT devices.

LCD triple USB charger limited to 5 V 2 A input

The charger draws 10 W from any standard USB wall adapter, car adapter or computer port via the included Micro USB cable. Its 4.2 V 0.5 A per slot output means each cell charges slowly, so three flat batteries will need several hours to reach full capacity.

5.18 Wh per battery suits light daily use

Each 1400 mAh pack delivers enough talk and standby time for typical office or home handsets. Heavy users who keep handsets off-hook for long shifts will find the capacity runs out before the day ends, requiring a mid-day swap.

Questions about this item

What capacity batteries are included in this pack?

Talk and standby time depend on the handset firmware and usage pattern; the 1400 mAh cell simply replaces the original N4FUYYYY0018 or N4FUYYYY0019 pack.
