This is the Plantronics Deluxe Travel USB Charging Kit for new models Savi W440 / W440-M, and Savi W740 / W740-M. This USB Charging Kit includes the USB charger itself and one (1) extra battery.
What it has to offer:
- Slide the headset into the charging cradle and charge it in the USB port of your PC
- May also charge the battery alone without it attached to the headset
- Charger has magnetic contacts, so battery stays in charger securely while charging (can even be upside down!)
- Charging cradle measures approximately 1 1/4" X 1" X 3/4" tall
- This kit is included in the box with W440 & W440-M USB wireless headsets
Please Note: you can replace the battery mid-call, without losing the call, as long as a charged battery is reattached within 5 minutes. This allows for unlimited talk time.
