A:Answeron the box its about 6-7 watts. it does work as long as you have a similar signal like this uses a bt4.2 so it should pair with most since my phone also uses bt low latency lg phone and older kyocera from 2006 .also cut off all bt around and pair transmitter with brick alone ---- it will find it. so you know other bt around will interfere with pairing causing loss of connection or none at all. once it has paired once ---- it will find it after with no issue.
A:AnswerI have had this connected to my computer, Ipod, samsung phone, and it has been easy. You have to make sure bluetooth is on whichever device you select, and I think you can only have it connected to one device at a time. So if you have it connected to a kindle, you will have to disconnect from that to connect it to another device like your phone, laptop, etc. Plus whatever device you are using can only connect to one device at a time, so if you have your phone, laptop, etc. connected to something else, you will have to disconnect from them to connect to this speaker. Switching back and forth is fairly easy.
A:AnswerI don't know how many watts, but it is pretty decent for the price. It is about 75% of the more expensive $100 speakers but it has excellent battery life.
