Compatible power for Attune handsets

This pack supplies two lithium-ion batteries and a triple USB charger built for Panasonic Attune 3020, 3050, Attune I, Attune II and Attune II HD3 models. It also fits WX-CH455, WX-SB100, WX-ST100 and WX-ST300 headsets plus KX-TCA285, KX-TCA385, KX-UDT121 and KX-UDT131 handsets. Each cell delivers 3.7 V and 1400 mAh for 5.18 Wh capacity. The charger accepts 5 V 2 A input via Micro USB and powers three slots simultaneously.

Steady charging across three bays

The LCD charger maintains a constant 4.2 V 0.5 A output to every bay so all three batteries reach full capacity at the same rate. Intelligent circuitry monitors each cell independently and stops current when the pack is full. A wall adapter, car charger or computer USB port can supply the 10 W input without changing the charge profile. The LCD panel shows real-time status and remaining capacity for every slot during the cycle.

Cool, quiet desktop operation

With no moving parts the charger runs silently and stays near ambient temperature during normal use. Total draw from the USB source never exceeds 10 W so any standard 5 V 2 A supply handles the load. The compact 3 by 2 by 2 inch footprint leaves minimal desk clutter. Buyers needing more than three simultaneous charges or a different battery chemistry will need a separate solution.
