A battery indicator is included in your WinBridge Voice Amplifiers so you can keep track of when they’re charging. Remove it from the charger when the battery indicator reads “full.” To avoid damaging the unit or the lithium-ion battery, do not overcharge it.
For WinBridge WB001 and other old or outdated units without a battery indicator, you will notice a red light at the top of the On/Off switch when it is charging. When it is done charging, the flashing red light will turn green.
Charging your WinBridge voice amplifier is easy. You’ll use the charging cord or charger that comes with your Voice Amplifier to charge it. The charging time is approximately 3-5 hours. When the battery is fully charged, the work duration might be somewhere between 10 and 12 hours, depending on usage.
You must care for and charge your voice amplifiers in the same manner that you care for and charge your other Bluetooth devices. Overcharging or discharging the battery might harm the device and reduce its performance. As a result, always charge with extreme caution.
