Engineered with a highly efficient Class D topology, this kit delivers 2 × 3W RMS across both channels while drawing only 0.5A to 2A, keeping heat output low and extending runtime when powered by DC 3.7V–5V sources such as USB chargers or lithium power banks. The machined aluminum alloy casing protects sensitive routing, improves structural stability, and acts as a passive heatsink for sustained performance. Native 5.0 Bluetooth provides stable wireless streaming up to 10 meters, while onboard digital decoders handle MP3, WMA, WAV, and FLAC files directly from attached USB flashes or TF\/Micro SD cards. Legacy gear connects instantly via the standard 3.5mm AUX jack or by scanning accessible FM bands, giving you four distinct input pathways in a single compact footprint.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Practical Usage Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eTrue Battery Operation: Route power from a standard 5V mobile power bank into the input screws for completely untethered listening during travel, picnics, or field recordings.\u003c\/li\u003e \u003cli\u003eVintage Restoration: Strip faded factory amplifiers from old boomboxes or wall-mounted speakers and replace them with these screw-terminal inputs for instant modernized clarity.\u003c\/li\u003e \u003cli\u003eFormat Selection Strategy: Reserve the TF card slot for high-bitrate FLAC music when critical detail matters most, and lean on Bluetooth 5.0 for everyday podcast or streaming convenience.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eOutput Power: 2 × 3W RMS\u003c\/li\u003e \u003cli\u003eFrequency Response: 20Hz – 20kHz\u003c\/li\u003e \u003cli\u003eBluetooth Version \u0026amp; Operational Range: 5.0 \/ Up to 10 meters line-of-sight\u003c\/li\u003e \u003cli\u003eInput Voltage \u0026amp; Draw: DC 3.7V–5V \/ 0.5A–2A (Quiescent: Approx. 15mA)\u003c\/li\u003e \u003cli\u003eSignal-to-Noise Ratio: \u0026gt;85dB\u003c\/li\u003e \u003cli\u003eTotal Harmonic Distortion: \u0026lt;0.05%\u003c\/li\u003e \u003cli\u003eSupported Playback Methods: Bluetooth 5.0, USB Flash Drive, TF\/Micro SD Card, FM Radio, 3.5mm AUX\u003c\/li\u003e \u003cli\u003eDecoded Audio Formats: MP3, WMA, WAV, FLAC\u003c\/li\u003e \u003cli\u003eHousing Material: Solid Aluminum Alloy\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage Includes\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e1 × Pre-mounted 2×3W Stereo Amplifier Unit in Metal Enclosure\u003c\/li\u003e \u003cli\u003e1 × Infrared Remote Control\u003c\/li\u003e \u003cli\u003e1 × Set of Speaker Terminal Connection Wires\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eOperating Reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eVerify wire polarity matches the terminal block labels before powering on to maintain correct speaker phase.\u003c\/li\u003e \u003cli\u003eEject storage media safely during use to avoid interrupting ongoing reads or corrupting playable files.\u003c\/li\u003e \u003cli\u003eThis platform requires an external DC 3.7V–5V power supply; internal batteries are not supplied.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eTrusted hardware specialists since 2002 — verifying component quality and consistent service at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"1PCS","offer_id":55111949123926,"sku":"1005010483599317-1PCS","price":14.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S79c3371efd7e4987aee2895269d83974M.webp?v=1787816233","url":"https:\/\/www.intercyprus.com\/products\/2x3w-mini-stereo-audio-amplifier-board-with-pbc-case-dc-3-7-5v-for-fiio-ampero-ii-diy-speaker-portable-power-bank-mobile-phone","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
