If I have a USB powered device, could I leave it plugged into a portable power bank (like the kind you charge your phone with) as a power outage backup? (lemmy.world)

Basically as the title says. We have semi frequent power outages where I live. The noise machine in my daughter's room goes out and wakes her up. If I were to buy a USB powered one, plug it into a power bank like one of those 10000ma ones you get for charging cell phones, would it have continuous power. Basically like a cheap UPS

I don’t think the ones I have would since you have to push the power button to tell it to start charging a plugged in device.
