Our take on the SI4732 Portable Radio 0.5-108MHz LSB AM FM Mini Pocket All-Band Radio Receiver

A tiny pocket receiver built around the Silicon Labs SI4732 chip, covering 0.5–108 MHz with AM, FM, shortwave and LSB single-sideband reception. It has a 1.9-inch color IPS display, a 3.5mm headphone jack, USB-C charging and an 800 mAh built-in battery rated for over 10 hours. The 3D-printed PETG housing and 19 g weight make it a bare-bones hobbyist device rather than a rugged field radio. No current price was supplied, so check the live comparison before buying.

Questions and answers

Is the SI4732 radio good for shortwave and SSB listening?
Yes, it tunes 0.5–108 MHz and supports LSB single-sideband, which covers most shortwave broadcast and amateur voice traffic. Sensitivity depends heavily on the antenna you attach, since the built-in one is tiny.
Does it have a speaker?
The listed audio output is a 3.5mm stereo jack with no speaker mentioned. Plan on wired headphones or powered speakers.
How long does the battery last?
The 800 mAh built-in battery is rated for over 10 hours of continuous playback. It charges over USB-C, and there is no hand crank or solar option.
What comes in the box?
Expect the radio itself; the listing does not detail accessories. Budget for a USB-C cable, headphones and possibly an external antenna wire.
Is it worth it over a Tecsun or similar pocket radio?
It is cheaper and smaller but lacks a speaker, weather sealing and brand support. Choose it for SSB tinkering; choose a Tecsun or similar for a finished, durable receiver.
When is it cheapest?
No price history was provided for this listing. Compare stores on the product page and watch for drops around sales events.
