Awesome little BT amplifier. Assembly required but it's super easy. Works amazingly well. I have it hooked up in my car powering a loudspeaker and it goes very loud indeed. Only drawback is the BT range is very short, like 20ft.

All my reviews are always 100% my personal opinion based on items I purchase for my own use. I never receive anything to review nor anything for my reviews. TLDR: Add a speaker and power supply and you have a bluetooth speaker. Pair with your phone or tablet and you have flawless radio with iHeart radio app (or your favorite app) independent of radio reception. Two of these for $20, one Magnadyne 5” Water Resistant Outdoor Wedge Speakers - Full Plastic Encasement with Grills - Pair for $25 and two 12V 2.5A Wall Power Supply for $14 and you have two 5" outdoor bluetooth speakers for $30 each. Not bad at all. We like listening to radio on front and back porches, but a couple stations come and go with the weather. Now using iHeart radio on our phones we have flawless radio listening independent of RF radio reception. On top of that, we have the best weather alert radio imaginable. While we are listening to our favorite AM or FM broadcast channel the weather alert will break in as we are using our local TV station weather app (ABC33/40) and that app gives us polygon specificity. No other AM/FM NOAA Weather Alert radio does that, and we didn't need to program a thing. Weather alert will alert you of anything the NOAA station is alerting for across multiple counties. S.A.M.E allows you to program for your county only. But Polygon from the local weather phone app is sub county (ie community) specificity. And with no programming. Just give it permission to access your location when you install it. Pretty cool tech all thanks to this little beast. You can get better speakers but at 12V you are only going to get 15W. I picked these magnadyne because they were inexpensive, 5 inch (good throat) and made for the outdoors (our porches). I picked the 2.5A 12V power supplies because they were least expensive. 1.5amp would have been plenty. I was about to get out my microscope to read the instructions when I found my jewelers loupe first. So I scanned in the instructions and attached them to this review so you don't have to hunt down your electron microscope. You're welcome! LOL I was surprised it actually held pairing even though I unplugged it. I know it said it would but it actually did. Cool! You can use two as mono stand alones or together in TWS for a single stereo. I own several radios. Not as many as radio Jay Allen but a fair few. Radios are like tater chips you cant have just one! But even the vaunted CCradio 2E/EP Pro and Qodosen Dx-286 have their limitations. Not even the Sangean CL100, PR-D4W or Midland WR-400 can boast flawless reception on every station AND polygon weather alert. Good to have a battery operated/backup weather band radio for emergency backup when the power is out but for plug in the wall 24/7, this is the way to go. And oh yeah, this could be operated by a car battery. Hmm...something to think about. Hope this helps.

This is a great little amplifier, plenty of power, and the Bluetooth connection is super fast. Very satisfied with the purchase.

This is a cheap amp but it works well driving a set of monitors. I use it for an AV setup at a cabin. It is paired with a firestick and an LED projector. It is as loud as you need it to be but doesn't distort at higher volume. The bass knob definitely affects the sound. The treble is much less noticeable. I use the 1/8" jack for the audio input from the projector and When not watching TV it leaves Bluetooth open if I want to put on the radio or music. Fidelity is fine for what it is don't expect it to outperform a high-end receiver, bust its damn good. I leave it powered 24/7 and it lasts about two years before it just stops powering up. It's a good option for a bit of sound to power some old speakers. I'm sure this is branded under several different names but the images and parts layout is all the same.

I used this for a transforming a vintage radio into Bluetooth for the fits time and it was really simple and intuitive to use, all the dials feel great, i will say I didn’t have a 12 volt charger so i had to get one but its pretty cool, seems good quality, light weight, smaller size and seems to sound pretty good, idk if it could sound crazy better because its already in a vintage speaker that doesn’t sound the best in general but works great for what i need, what i did notice though was I couldn’t keep the volume completely quiet at my phones lowest volume because you’d still hear the music coming from the speaker but i fixed that by adjusting the volume to be loud enough for when id want full volume and adjust the dile to be low enough to not let sound come through when i wanted to put my phone quiet

i needed some sound for a PC i was using, Put this on a old kenwood surround sound speaker w/ tweeter. Used a simple 12v 1. amp power supply from some old netgear modem i had. Love the BT option as well as aux input option.. aux cord is nice for old pc... BT is nice if i wanta listen too tunes from my phone.. If you got a decent power supply like more amps, and or volts, this thing will make even a 15" subwoofer make sound.. I love the trbble and bass adjustments.. i just wish the pot's for the knobs were longer so i could hide this in the old speaker, and drill holes for the knobs.. I could see using this in a car, if just wanted some sort of sound, for connecting too your BT phone.. atleast for OUTPUT.. long as there a speaker or 2x somerwer too hook it tooo, and 12v and atleat 1 amp, youll be able too hear sound great, atleast if you keep bass down.. DEF' gonna buy some more of these, prob' the btter ones with more tunning options... only complaint, i wish it was sealed better, and maybe had screw holes too mount it.. nothin that you cant diy' yourself and figure out either way.. PLENTY LOAD ENUFF FOR A SMALL CAR OR, PC SOUND FOR GAMING..

I just realized this is a replica of the ZK-MT21, but honestly it works really well. For such a cheap amp, I can’t complain. Let’s see how long it lasts. Used an old 12V Power adapter from a router I dont use and I just gave my old Sony speakers a "new life" with this mini amp. Bluetooth works immediately after turning device on, I tested with my iPhone and worked just fine.
