portable cd player with usb output

Most portable CD players with USB support offer direct playback from a USB flash drive (commonly for music files), and many list support for USB drives (often up to 128 GB). Some models include USB ripping/recording to save CDs as WAV files to a USB device, and a few can be powered via a USB adapter. Exact features vary by model.

Many players have no built-in storage and rely on external USB drives. Where manufacturers specify a limit, supported USB drives are commonly listed up to 128 GB, but exact maximums vary by model.

USB playback most commonly supports MP3 files; some models also support WMA. Separately, at least one model can rip CDs to WAV files when recording to a USB device.

Common extras include Bluetooth streaming, AUX input, headphone jacks (3.5 mm), and FM/AM radio. Larger models often add RCA/composite outputs; some players also support SD card playback and optical/coaxial digital outputs.

Most units play standard audio CDs as well as CD‑R and CD‑RW. Many also support MP3 discs or MP3 files from USB (MP3‑CD compatibility is commonly listed).

Available digital outputs include optical and coaxial audio connections. Many units also provide line outputs (3.5 mm), some higher-end models offer balanced outputs, and larger boomboxes include RCA/composite A/V outputs.
