How do you manage the battery? I would be afraid of a fire after x years being on all the time.

Note that I have no specific knowledge on the subject ; it's quite possibly a fear without any reasonable ground.

But I had a cheap speaker that I used with a Chromecast audio to listening to podcasts ; I left it always on and... I came back just in time one night, the speaker was producing a large dark smoke.

I almost put fire to one of the oldest habitation building in Paris (1704) - with a lot of apparent wood etc. :-(

Not proud of it, but good lesson. I recently read about the risk of fire in cheap replacement phone chargers. Google's ought to be of quality but... still a no-no for me.

Obviously, advice from people with knowledge on the issue will be appreciated.
