A:AnswerHi!
Yes, the speakers can be connected to some TVs, as long as they are Bluetooth compatible. The TV should allow you to scan and choose the speaker being connected in order to connect properly with the Solar Stone.
I hope this helps!
A:AnswerThe batteries last about 48 hours with no solar input, but can last much longer if the units are in the sun. It takes about 6 hours to fully charge the batteries using the AC power adapter. You'll certainly need to provide AC power to these to keep them on 24/7.
A:AnswerThere are Bluetooth dongles that you should be able to plug into the headphone or main output of your stereo. ION does not manufacturer such a product and recommends streaming to the Solar Stone from a device such as a smart phone or tablet.
A:AnswerTwo thoughts, move them closer as mine had a similar issue. And they may not be as charged as you think. I plugged in for awhile and moved them closer and seems to fix my problem. Did you fully charged when you first used ?
A:AnswerI think it is less than 30 feet. It makes funny noises when you get too far away. But my phone is usually with 15 feet or so and it sounds great at that distance.
A:AnswerYou can plug it in. But it is solar powered as well. Will work continually for 30 hours on one charge. But if in the sun. It won't run out of power. I'm very impressed with mine.
