Triple USB Charger for Panasonic DECT Headsets

The Kastar LI-42B LCD charger powers three compatible Li-Ion batteries simultaneously. It targets offices and call centres that keep Panasonic KX-TCA285, KX-TCA385, KX-UDT121 or KX-UDT131 handsets in constant rotation. The unit also supports the Attune II HD3 and WX-CH455, WX-SB100, WX-ST100 and WX-ST300 models.

Thermals and Power Draw

The charger draws 5 V at 2 A for a 10 W input and delivers 4.2 V at .5 A to each of the three bays. No active cooling is fitted; the small 3*2*1 Inch enclosure relies on passive dissipation during normal charging cycles. Operation stays silent, making it suitable for desk-side use in quiet environments.

Build and Daily Connectivity

A Micro USB cable is included for connection to a wall adapter, car charger or computer USB port. The intelligent LCD panel shows individual charging status and remaining capacity for every battery. Its compact footprint allows easy transport between workstations or off-site deployments.

Questions about this item

How do I connect the Kastar LI-42B charger to power using the included Micro USB cable?

Plug the Micro USB cable into the charger and connect the other end to a 5V 2A USB wall adapter, car adapter, or computer port. The charger draws 10W and outputs 4.2V at .5A per slot for three batteries simultaneously.

Will the LCD screen or charging contacts need cleaning or replacement after extended use?

The LCD display and spring-loaded contacts are built into the charger body. No user-replaceable parts or scheduled maintenance are described; keep contacts free of dust with a dry brush if needed.

At what point does the .5A per-channel output become the limiting factor during sustained charging?

Each of the three channels delivers a fixed .5A at 4.2V. When charging three depleted Li-Ion packs together, this current ceiling determines the minimum recharge time and cannot be increased.
