BP MINI Acoustic Guitar Amplifier, 30 Watt Bluetooth Speaker Rechargeable Portable Amp with Microphone Input Supports Volume Bass Treble Control Reverb Chorus Effect

The BP-Mini amp works very well and is light and portable. While the bass isn't as deep as some popular Bluetooth speakers, this may be because the sound is more neutral. I'm not a sound engineer, but I find the overall sound quality good for its purpose. It amplifies my small piezo-electric pickup with ease, and the Bluetooth connection works without any issues. The volume is impressive for its size. I haven’t tried the microphone input yet, but so far, I’m happy with its performance. One interesting feature is the 3.5mm "Phone (live)" jack. The manual suggests this is a TRRS (4-pin) jack for streaming audio out, but the instructions are a bit cryptic. I’m still experimenting to see how this functionality works in practice. The battery life seems solid so far, though I haven’t tested it in extended performances. However, charging is a mixed experience. While the seller states the battery should charge in about 3-4 hours, it took me over 8 hours to fully charge from dead. Using a capacity monitor, I measured around 10,400 mAh for the battery. The seller confirmed the battery capacity is 38.48Wh, which likely corresponds to four 18650 cells. PROS: Good sound level and range Excellent amp for instruments Reliable battery life for regular use CONS: No PD support: The amp doesn’t charge from PD (Power Delivery) sources, which limits charging options (confirmed by the seller). No reverse charging via USB-C: While it has USB output, the amp isn’t a power bank, and the USB-C port doesn’t support reverse charging (confirmed by the seller). Charging time: Charging took significantly longer than expected. Additionally, earlier versions of the amp reportedly included a USB power adapter. The newer version only comes with a USB-A to USB-C cable, which the seller also confirmed. Overall, I gave this amp 5 stars because it performs exceptionally well for its intended purpose. If you're looking for a reliable and portable amplifier for instruments, the BP-Mini is a great choice!

I’m really impressed with the Coolmusic amp. Despite its small size, it produces a clean and natural sound that would work well with acoustic guitars. The 30-watt output is more than enough for home practice and small performances. I like that you can connect your phone up to it through Bluetooth as I love to listen to my music through a portable speaker and this one delivers great sound quality, though just be careful you don’t turn it up to high as this mini amp packs a lot of power. It’s lightweight, easy to transport, and very user-friendly. For the price, this amp is everything you need though the only downside is that it doesn’t come with a carry case.

Well this little baby is amazing! Portable, lightweight small speaker with a full set of controls on the top and a carrying handle. Marvellous sound quality, I was really very impressed with that for a small amp. Bluetooth - so you can pair it with just about anything. It even has two inputs (one for a mic, one for an instrument) and both very easy to balance with volume, bass treble and reverb, (+chorus for the instrument input). There is also a separate master volume control as well as the individual port socket volume controls. Reverb is heavenly on the mic output. There's a plug to plug in a mobile phone, although I haven't used that. On the back are aux in/aux out/charger and a headphone socket. I haven't used any of these yet, so can't comment on those. You tube karaoke videos paired with the tv, or your own music paired from anything with bluetooth capability. Fully rechargeable as well - no plugs required for a few hours or more. I've only run it for a few hours at a time, but the charge remains at over half way in that time, so I estimate it would run for around 4 hours on a full charge. I've knocked a star off for the charger and charger socket. The socket on the back of the amp is flimsy, so you need to be careful you don't damage it when you plug it in to charge it. The three pin plug on the other end seems a bit too small for my UK wall plug sockets, and I have to really push it in really firmly to get it to charge. The instruction leaflet is a bit lacking as well, but just about useable. Don't let the above charger problem put you off though, it's an excellent all rounder for buskers, outdoor performers and indoor closet karoke YouTubers! It would also be great for providing background music at the BBQ in the garden as you can just use it as a speaker if you like (but try not to annoy the neighbours -it's quite loud!!) If the manufacturers could just make that charger socket and charger a bit less flimsy at either end, it would have got five stars from me. I'm thrilled with it.

Hace un par de años compré este amplificador para hacer un regalo a una persona cercana. Me encantó en cuanto lo probé, y, finalmente, lo he comprado también para mí. Me parece una pasada. Pequeño, muy potente para su tamaño, sonido limpio, transportable, con batería que dura bastante... Mi idea es usarlo con instrumentos acústicos. Lo he probado con guitarras y con bajo acústico, y es espectacular. Aún no lo he probado con otros instrumentos eléctricos ni con micros. Por ahora estoy tremendamente satisfecho. Si tuviera que poner una pequeña "falta", o algo que lo haría aún más satisfactorio, es que, ya que es tan transportable, sería estupendo que tuviera una funda ligera que lo protegiera al menos un poco del polvo cuando no se usa y de rayaduras cuando se transporta. Creo que acabaré fabricándole yo una. Cada vez que lo uso, me dibuja una sonrisa!

Den här gitarr-förstärkaren är helt fantastisk. Två separata ingångar en för gitarr en för mikrofon. Det funkar utmärkt att även plugga in keyboard. Bluetooth funkar klockrent. Och det bästa är väl att det är ett sånt jäkla tryck i stärkaren. Batteriet räcker länge. Jag spelade effektivt i säkert 6-7 timmar. Men den måste ladda i uppåt 8-9 timmar för att bli fullladdat. Bästa förstärkaren på nätet. Trots det låga priset. Tummen upp.👍

Der Amp kam gut verpackt an und ist wie in der Anzeige beschrieben. Eine handliche Größe und, soweit ich das sehen kann, auch gut und solide verarbeitet. Der Tragegurt ist aus Gummi und könnte etwas hochwertiger sein, aber das ist nur eine Kleinigkeit. Der Sound ist der Größe entsprechend OK. Batterie lässt sich nur über USB laden, ein Ladekabel lag wie beschrieben auch dabei. Die Tatsache, dass ich meine Gitarre und mein Mikrophon anschließen kann ist wirklich gut. Für Hobby und Abende am Lagerfeuer genau das richtige.

Excelente calidad precio, lo recomiendo ampliamente

元々の着眼点は凄く良い商品だと思います。 改造するとダメなところが改善されるので、物凄く化けます。
