Amplifier battery & charger questions:
What kind of batteries do the amplifiers use?
The SoniVox® waistband amplifier uses 8 AA batteries. Rechargeable batteries are included.
The SoniVox Plus™ personal amplifier uses an internal lithium battery.
The BoomVox® portable wireless amplifier uses a 9v battery in each of the transmitters. The amplifier itself has a 12v gel-cel battery built in. It may also run on an 12v automobile supply, or 110v AC power. Two disposable 9v alkaline batteries are included for the two transmitters.
Do the amplifiers come with battery chargers?
Yes. The SoniVox® waistband amp includes a constant-current charger which will charge the batteries in about 7-10 hours. Note: Do NOT charge alkaline batteries!
The SoniVox Plus™ personal amp includes a micro-USB charger which will charge the battery in about 3-5 hours.
The BoomVox® wireless amp has a built in charger. This charger will charge the 12v gel cell battery, and trickle charge one 9v battery. Note: Do NOT charge alkaline batteries!
How long do the batteries last in the amplifiers?
All three of our amps, including the SoniVox® and SoniVox Plus™ personal amplifiers and the BoomVox® wireless amp, will last most teachers a full day of teaching. Teachers who lecture heavily may need to top off their batteries at lunch time and/or during their prep period, but this is rare.
