Compatible Panasonic Headsets

This kit replaces batteries for Panasonic WX-T3020, WX-H3030, WX-H3050, WX-CH450 and WX-CT420 headset systems. It includes two 3.7V lithium-ion cells and a matching AC wall charger. The package suits professionals who need reliable power for wireless headset fleets.

Battery Capacity 7.03 Wh

Each cell delivers 1900 mAh at 3.7 V for a total of 7.03 Wh per battery. The charger accepts AC 100–240 V at 50–60 Hz and outputs DC 4.2 V at 600 mA. These figures decide whether the kit matches the original runtime and charge speed.

Foldable Plug Charger

The charger uses a foldable flat plug for compact storage and plugs directly into a wall outlet. A red LED shows charging and a green LED shows standby or full charge. No cable routing or dock is required; the only common issue is forgetting to flip the plug out before inserting it.

Questions about this item

How long will the 1900 mAh cells actually power my Panasonic WX-H3030 headset?

Each 3.7 V, 1900 mAh lithium-ion pack stores 7.03 Wh, giving typical talk time of several hours on the WX-H3030 before needing a recharge.

What does the charger’s 100-240 V input and 4.2 V 600 mA output mean for daily use?

The wall adapter accepts any mains voltage from 100 to 240 V at 50 or 60 Hz and delivers a steady 4.2 V at 600 mA, so it charges both batteries worldwide without a separate transformer.

Will the 3 by 2 by 2 inch charger block adjacent outlets on a power strip?

Its foldable flat pins let the unit sit flush against the wall or strip, leaving neighbouring sockets free for other plugs.
