This is a very compact little amp (40mm high, 120mm wide and 160mm deep). It has a good quality feel and a reasonable weight to it. I am using it to drive 2 Q Acoustic Speakers (2020i) that are rated 75 watts at 6 Ohms. I have the amp connected via banana plugs. I would say the amp matches these really well and drives the speakers fully. Not too much and not too little. At max volume there is a touch of distortion but not that much and honestly whilst I do like loud music, I would not really want my music that loud in the kitchen, I have another set up for that elsewhere. The treble and base adjustment may in some ways seem old fashioned but I really like them as you can give it a little more base or treble depending on your speakers, the music and of course your personal preference. You can get graphic equalisers to add to your phone, etc, but the on-amp adjustment just seems more accessible. I am not using the bass driver and honestly I do not think I will. So why did I buy this amp when Fosi do a version with no bass driver? Well, desertcart had a discount that made this version only £5 more than the non-bass driver version. Another reason though was that this comes with a 32 volt power supply and the non-bass driver version ships with the 24 volt supply but can be upgraded to the 48 volt supply. This means you will not get full performance if you only buy the one that ships with 24 volt supply. You can upgrade on the Fosi website but not on the desertcart website. You can buy the 48volt power supply separately on desertcart but this pushes the price up quite a bit. So, therefore I preferred this slightly higher spec model that ships with the 32 volt supply from desertcart and this is the max supply allowed for this unit, I think. That was my logic and it would be interesting to know what Fosi themselves think about this and whether my deductions were correct. I think Fosi should add the 48 volt power supply option to the non-bass driver unit on desertcart. I use this in my kitchen and for me a key selling point is the size. I have built it in to the bottom of one of my kitchen cupboards and of course its small size means it is very discrete. The Bluetooth works fine. Still good volume. It connects easily and makes a little bleep to signal connection. You can also connect directly if you have the right cables. The sound quality and volume are marginally higher and cleaner when connected directly, but the Bluetooth still sounds good. My arrangement slightly compromises the view to the Bluetooth antenna, which I have rotated so it is exposed somewhat. This does not seem to make much difference and the range is still fine. I am using it with iPads, iPhones and Samsung phones. All work fine. So I am very happy with this Fosi unit but I would recommend you look at their full range, perhaps on their website before you decide the best one for you. I went for desertcart because I knew it would come quickly and be an easy return if I did not like it. I am a bit shocked and pleasantly surprised that such a tiny and affordable little unit can be so good. Well done Fosi. (Ultimately I decided to get the non-bass model with the 48 volt power supply. This does give slightly greater volume with less distortion which is why I have updated this review.) Review: Incredible - Arrived in a fair sized box - then you open it and go 'No way'. It's tiny, maybe as big as 2 Nurofen packets on top of each other. Is this gonna make any sound at all? (I'm used to 19 inch Cambridge amps etc). Well flippin eck, it does. I was gonna use it to power the sound on my tv, a Hisense, into Gale bookshelf speakers, which can sound amazing. All you do is attach the speaker cable, then the tv and the Fosi amp found each other straight away via Bluetooth...and boom. Big sound, happily supplying the speakers with all they needed. And it sounds great! I just set the unit's volume to 12 o'clock and control the level via the tv remote, never touch it. For £60 this thing is startlingly good, and let's be honest cheap as chips. ## Features - 【Bluetooth 5.0】Featuring an integrated Bluetooth ATS2853 chip, this bluetooth amplifier supports streaming up to 50ft (15m), connect to your MP3/Phone/Pad/PC via Bluetooth input, 19V 4.74A power supply and 50W x2@4Ohm support to drive 2-8 Ohm speakers. - 【Compact Design】Our mini amplifier offers a sturdy, space-saving design for home, office, or outdoor use, with bass and treble controls, small and neat, simple compact design but practical and powerful. - 【Excellent Chip】Power amplifier TI TPA3116D2 chip to get clear and clarity sound.Advanced circuitry design, built-in speakers protection circuit, no audible noise, dead silent when nothing is playing through it. - 【Superior Sound】This stereo amplifier, crafted for HiFi sound lovers, produces crisp, clean audio with crystal-clear highs and smooth, pure bass.

II need silver. Thank you.** A: silver **Q: Is it possible to turn bluetooth off ? I want to make sure there isn't any interference.** A: No, the BT is just on, so there is no 'off' button and it's just passively waiting for a BT connection. It would only switch to BT if you connected to it and played something. I rarely use BT, as I tend to use the Aux input from a switched box to select either an Amazon Echo Input or an Apple Airport. I've never had any interference problems with it and get a great sound out of it - put through a speaker switch box to allow me to have up to 4 outdoor speakers, each individually selected. **Q: What's the difference to fosi audio bt20a please? better bluetooth reception, better sound?** A: The BT20a offers 2ch x100watts ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Good Little Amp *by S***R on 22 February 2024* I am quite picky and want a clean, high-quality sound with plenty of volume when it comes to hifi.

For £60 this thing is startlingly good, and let's be honest cheap as chips. ### ⭐⭐⭐⭐⭐ Great compact amplifier *by J***H on 14 May 2024* Last year I had bought a Tangent Ampster BT II amplifier, which had worked great, however it recently had an issue with the power switch, so had to be sent away for repair. As I used it in my office I needed a replacement and decided to order this amplifier. I thought the Tangent Ampster was small, but this BT20A amplifier is ridiculously small! This is mainly as the power supply is external to the amplifier, which itself is bigger than the amplifier. I have it connected to a pair of Mission LX-1 MKII speakers, and I am happy to say that this amplifier easily runs these speakers, with no sign of distortion. I appreciate the treble and bass controls, as by default the treble did sound lacking and a bit stifled. The dials are nice and smooth, and the power switch toggle works without issue. At this size and price you only get 1 set of RCA inputs and 1 set of speaker outputs, but for my use case this is fine. Bluetooth works seamlessly, and the audio quality is about on par with direct RCA connection. Be aware that if you connect via bluetooth it will override the RCA input, even with no music played over bluetooth. I will say, as others have, that being able to connect to the amplifier via bluetooth without being asked for a code is a potential issue, I live in a block of apartments, so anyone could connect to it if they tried. I don't hear any hissing when not playing music, so that is another plus. Overall a great little amplifier for the price, once my other amp is back from repair I will probably relegate that to the living room as it has a remote control that is more useful. ## Frequently Bought Together - Fosi Audio BT10A Bluetooth 5.0 Stereo Audio Amplifier Receiver 2 Channel Class D Mini Hi-Fi Integrated Amp for Home Passive Speakers 50W x 2 TPA3116 - Banana Plugs with Dual Set Screws,Black and Red Aluminum Shell,6 Pairs - Amazon Basics Speaker Cable, Easy Assembly, 16-Gauge, Bronze, 100 ft --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/65694519-fosi-audio-bt10a-bluetooth-5-0-amplifier-stereo-power-amplifier](https://www.desertcart.pe/products/65694519-fosi-audio-bt10a-bluetooth-5-0-amplifier-stereo-power-amplifier) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-07-09*
