Question: Can the Avantee Saturn be left on charge indefinitely??
Document: I initially bought this product to connect to a projector. My plans was to send the audio single from the projector to a Bluetooth sound bar with a wireless subwoofer. The projector is attached to the ceiling. I tested the Avantee Saturn Bluetooth in two different places and on two different system. Once I hit a 13 feet range away it was hit and miss. The music was in and out, a lot of static. When I was fifteen feet away it only became worse.
The device has to been plugged into a USB port to charge it.
holds a charge for a good time, but best of all it can transmit and receive. I just move it from device to device
The perfect upgrade to to my previous adapter. I needed something reliable that held a long charge. This actually outlasted the charge on my ear buds.
i baought this to play music and podcasts from my ipod and android phone it works verry well. it lasts at least 8 hours on a single charge. glad i bought this
Works flawlessly except for the extra noise when listening and charging at the same time. Charge it during nights.I'm using it with a pair of Phillips Fidelio BT-phones. Excellent sound!Very fast delivery from Amazon!
Reception? I don't know.6)  I had terrible, terrible sound quality until I realized that the Avantree absolutely needs to be fully charged before its first use. You have enough charge to turn it on, but it will sound like crap and you'll return it as defective.
I could not get this unit to work properly.The battery would not charge fully even after 10+ hours.Lots of static; probably caused by a defective battery.Returning it for refund and continuing to look for something that works the first time.
The receiver part works, I have not had a chance to use the transmit. It comes with a cable and a simple jack to jack connection connectors plus a USB to mini-USB to charge the battery. It would be nice to find a Bluetooth device that would tx and rx without having to flip a switch.
In my BRZ the unit will, without fail, turn itself off after around 5-10 minutes. However, I suspect that is due to the current from that specific adapter, which goes into the MicroUSB port, being very low (there is a USB output meant to link up the ipod in that car which I use with a MicroUSB port to charge this adapter), rather than an issue with the adapter itself.
Answer: Yeah, no problem. Don't worry :-)
