I am a media maven; I listen to public radio every day. For years I got by with a Sangean portable but it used up batteries like they were potato chips. So I bought Panasonic rechargeable batteries for it, but found that their voltage wasn't quite right and therefore the radio quality suffered. I figured it was time to buy a radio that was inherently rechargeable. So I read the reviews and selected the DX-286 from Qodosen. When it arrived I was surprised to see its credit-card size. The good folks at Qodosen shoehorned every technical capability into this tiny radio, but it's way over-engineered and became more of an irritant than a convenience; how do you set this thing? How do you turn off the alarm? And the kicker was that the sound was tinny and unsatisfying. I tried living with this for months and finally decided that I owed it to myself to find something easier to use and better quality. A few days ago my PowerByte arrived. Immediately I could tell that this was a substantial product. It is heavy! It has large speakers. But there is tremendous value in this radio. First, it is extremely logical and easy to set up and use. When you turn it on for the first time, it automatically scans and stores all available FM stations. And designating a particular station as a favorite (there are 9 spots for this) is as easy as doing so in a car. Everything about the design is simple. There is a nice, old-fashioned dial for power and volume. The buttons are at the top and have simple functions. The EQ button gives you a choice of three settings - one balanced, one for speech (which lessens the bass) and one for maximum bass. The speakers in this radio are superb. They sound good at any volume, but if you want to crank it up for, say, a party, you could not find anything better than this. The unit is rechargeable through USB. It takes about 3 hours of recharging to run for 20 hours...although you may want to just leave it plugged in. Unlike some other units, this one can run with the charging cable plugged in. I have not yet tried it with Bluetooth, and I have no need of plugging in SD cards or a USB drive. For me, the PowerByte serves its purpose as a superb portable, rechargeable FM radio which, based on my many years of experience with audio, sounds just right. Highly recommended. Review: Bass is tight and forward, sounds great. - Bass is tight and forward, sounds great. No rattles or vibrations. Power output seems more than enough, plenty of pump and muscle. EQ selections are a bit so so, would have been good if there were more than 3 EQ presets. Bluetooth works well, connected to my phone quickly. Handle is fixed, shame it wasn't designed to fold down. Product is well made, price is very reasonable. I use this when away camping and it rocks the bush! Only one gripe is It's not water resistant. Highly recommended! ## Features - [POWERFUL SOUND] The PowerByte’s 30W drivers and bass radiators produce incredible volume and amazing stereo sound with immersive left-right speaker separation. - [24/7 PLAYTIME] Enjoy up to 20 hours of playtime when operating via the rechargeable battery, or keep it plugged into a power source for nonstop listening. - [5-IN-1 FUNCTIONALITY] Use the Avantree PowerByte to enjoy your favorite FM radio stations, stream music from a Bluetooth enabled device, play audio from either a USB drive or an SD card, or as a wired speaker. - [CLEAR FM RECEPTION] Extend the external antenna and enjoy enhanced FM reception that allows you to listen to your favorite FM radio stations with crystal clear sound quality and without interruptions. - [EASY TO USE] With a large knob control, a clear LCD screen, and intuitive, individually labeled buttons, you can easily find, save, and play your favorite FM channels. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CPHM72KZ | | Antenna Location | Music, News | | Best Sellers Rank | #741,784 in Electronics ( See Top 100 in Electronics ) #4,344 in Bluetooth Speakers | | Box Contents | PowerByte Radio, USB-C Charging Cable | | Brand | Avantree | | Brand Name | Avantree | | Colour | Black | | Compatible Devices | Speaker, Smartphone, Headphone, MP3 Player, Tablet, Laptop | | Connectivity Technology | Bluetooth | | Country of Origin | USA | | Customer Reviews | 4.4 out of 5 stars 448 Reviews | | Display Technology | LCD | | Display Type | LCD | | Frequency | 108 MHz | | Hardware Interface | USB | | Item Dimensions L x W x H | 23.5L x 19.6W x 11.2H Centimeters | | Manufacturer | Avantree | | Manufacturer Part Number | BTSP-880 | | Model Number | BTSP-880 | | Network Connectivity Technology | Bluetooth | | Number of Batteries | 1 C batteries required.

If very few stations are found, hold the FM button for 2 seconds to run another scan. **Q: Does the PowerByte have AM reception?** A: No, the PowerByte only supports FM reception. **Q: Can I use the PowerByte while it’s charging?** A: Yes, the PowerByte is fully functional while charging. **Q: What file formats does the PowerByte support for SD cards and USB flash drives?** A: The PowerByte supports MP3/WAV/WMA files with storage devices up to 32 GB (SD card or USB flash drive). **Q: Are there any limitations for WAV files?** A: PowerByte doesn’t support WAV files with sampling rates of 88 kHz or higher. Standard 44.1 kHz and 48 kHz files work fine. Bit depth (16/24-bit) does not affect compatibility. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best in the class *by N***N on 25 November 2025* What a marvelous radio this is!

Highly recommended! ### ⭐⭐⭐⭐⭐ Son vraiment excellent ! *by C***N on 3 June 2025* Belle fabrication, utilisation facile, radio, lecteur de carte micro sd, clé USB, bluetooth,entrée aux , bref c'est ultra complet ! Capte bien les stations fm. Dispose de 3 égaliseurs (préréglés) . Écran avec indication de l'état de charge ( très utile ! ) Mais là où c'est vraiment parfait, c'est la qualité sonore ! Les basses vraiment top !! J'ai essayé pas mal d'enceinte portable mais celle ci est sans aucun doute la plus complète et avec la qualité sonore au rendez vous. Un Sans faute !! Juste faire attention car elle n'est pas étanche ! Autonomie après essai, 3 journée de 9h sur chantier à faible volume reste une barre de batterie, donc plus que raisonnable ( 29h environ à faible volume) !!
