I was hoping to use this in a home-brew battery guitar amp project but sadly it just doesn't have enough power

Like other reviews, you have to fined the right power supply.

Careful what you pay for with an amp, this will blow subs left and right just from giving super dirty power

It works great as a beginner amp, had some speakers laying around, had the popular lepai amp works great too, it definitely more power

ACTUAL Amplifier Power Requirements Depend on theSignal Feed Level, Volume Control Setting, and the Output Speaker Loading (impedance).The Amp, will work best with Speakers @ 8 to 4 Ohms, to get the desired best POWER TRANSFER to Speakers!4 Watts per Speaker, is NOT Un-realistic, and Actual Amperage Input

It has enough power for a small use case like this.

Make sure you purchase or have the correct power supply

This amp produces no apparent noise on its own but it will pass though some power supply noise, so I had to find a quiet power supply for it.

Works great powering a pair of bookshelf speakers that sit beside my TV, being driven by a shoebox computer system I use as a HiDef media player.

This is an excellent mini power amp.

I used the recommend power supply that others have used also.

Works ok, low power

It's industry practice, not just to save costs, but because a buyer can elect to give the amp more power or less power than recommended

Works well, powers some speakers for my PC

Works excellent, I use it to power bookshelf speakers in my RV.

It is not a good sounding amp even with ample power supply

Smart nice little amp nice sound and power

I would like a bit more power, but in this size case, which fits nicely in my center armrest storage, I can't really complain.

I hooked it up to a nice power supply 5A, Fed it with a sansa clip with Wav quality files, tried it with & without the new Fiio portable E11 Kilamanjaro amp, & to top it off sent that to a pair of Paradigm Atom S7 speakers, NOT efficient at 86db power hungry rating

It even works being powered from the phone line

I had an old Yamaha cube style speaker system with a powered subwoofer (like the Bose cubes) laying around.

Careful what you pay for with an amp, this will blow subs left and right just from giving super dirty power

it was a little plasticy but smooth knobs and easy, powered room at upper ambient volume, clipped at upper end

Great little mini power amp

Very good power for the little guy it is also a good nightlight if your not a fan of the dark like myself!

Buy a decent power supply, at least 4 amps

No power cord but works better than expected

I added the appropriate 12v power-supply with correct amperage rating.

Not quite enough power for the

The power is not an issue with headphones but the noise is.

I'm using it to power two outdoor speakers, and it works fine

This little amp has great sound and perfect power for a set of patio speakers

Doesn't put out much power, but that's really not an issue for $10, is it

RCA connectors are used as the R and L input, perfect.
