What it does
A palm sized stereo amplifier that powers a pair of passive speakers from Bluetooth, USB or a 3.5 mm aux input.
- Small enough to hold in one hand and sit on a desk
- USB input works as a computer sound card with no driver install
- Bluetooth 5.0 for streaming from a phone or tablet
- Aux input for wired sources
- Ships with its own power supply, so it is ready to use
A cheap, small way to turn a pair of passive bookshelf speakers into a Bluetooth or desktop computer setup. The rated 50 watts per channel is the maker's figure with little independent testing behind it, and there are reports of some white noise when using the USB input.

Questions
Does the Nobsound mini amp need drivers for USB?
No. The listing and a published review both say USB playback from a computer works without installing drivers.
Does it come with a power supply?
Yes. Current listings include a 19V power supply plus aux, USB and RCA cables.
Is it really 50 watts per channel?
That is the maker's rating. No independent power measurement of this exact model turned up, so it is best treated as an unverified figure.
Can it power bookshelf speakers?
Yes, it is sold for use with passive stereo speakers in home, office and desktop setups.
