usb cd radio

Power options vary: some portable models use replaceable batteries (e.g., AA or C cells), others rely on an AC adapter, and a few can be powered or charged via a USB/mini‑USB connection.

Most players support standard discs (CD, CD‑R, CD‑RW) and MP3 playback. Some receivers and units with USB inputs also list support for additional file types such as WMA, WAV, AAC and FLAC from CD or USB.

Sizes range from compact personal players (example: 5.71 in H × 5.55 in W × 1 in D) up to larger tabletop units (example: 4.09 in H × 10.24 in W × 14.71 in D). Weights in listings span from about 0.5 ounces to 5.5 pounds, depending on model and features.

Common extras include built‑in speakers and digital tuners, Bluetooth streaming, USB ports (some for charging), LED displays, clocks with dual alarms, remote controls, and—on some models—Qi wireless charging pads.

Speaker and power specs vary: some compact boomboxes list around 4 W RMS stereo output from dual 2.5" full‑range speakers, while larger tabletop units may list higher outputs such as 8 W × 2.
