Compatible Handset Models

This Kastar pack includes two lithium-ion batteries and a foldable AC wall charger built for Panasonic DECT handsets. It fits the KX-TCA285, KX-TCA385, KX-UDT121, KX-UDT131, Attune II HD3, WX-CH455, WX-SB100, WX-ST100 and WX-ST300 models. Each battery delivers 3.7 volts and 1400 milliampere-hours for reliable talk time.

Charging Limits

The charger accepts AC input from 100 to 240 volts at 50 or 60 hertz and supplies DC output at 4.2 volts and 600 milliamps. A red LED shows active charging while a green LED signals standby or a full charge. The foldable flat plug reduces bulk when the unit is stored or packed for travel.

Installation Notes

Users simply insert a battery into the charger and plug the unit into a wall outlet; no cables or cradles are required. The foldable prongs can catch on tight power strips if adjacent sockets are occupied. Buyers needing to charge more than two batteries simultaneously or wanting a desktop cradle will need a different solution.
