The Go to product viewer dialog for this item. (often branded by HanRongDa or ZHIWHIS) is a highly popular, ultra-compact portable AM/FM radio. Its standout feature is its comprehensive digital memory system, which allows it to store up to 58 preset stations (29 for AM and 29 for FM). Key Features of the

Alternatives and complementary sensors

• Infrared (IR) proximity: better for small, reflective targets at short ranges; affected by ambient light.
• Time-of-Flight (ToF) LiDAR (VCSEL+SPAD): higher accuracy and longer range in compact modules; more expensive.
• Radar (mmWave): better through dust/fog, multiple-target resolution; higher power and complexity.
• Optical stereo or structured light: rich environmental mapping, heavier compute and lighting sensitivity.

• How it works: It delivers sound waves in pulses, rather than a continuous stream.
• Why it's useful: It provides the mechanical benefits of ultrasound (reducing inflammation, speeding up cell repair) without heating the tissue. This makes it safe to use on acute injuries (like a fresh sprain or swollen ankle) where heat would be contraindicated.

The URE103 stands out in the crowded portable power market due to its power-to-weight ratio. Its dimensions of 240 x 140 x 220 mm make it small enough for vehicle storage or manual transport. Capacity: 1036Wh (high-density Lithium-ion) Weight: ~3.9 kg (approx. 8.6 lbs)

Selectable AM Steps: The medium wave (AM) step value can be adjusted between 9KHz and 10KHz to match different global regional standards. Usage Considerations

Quality: It does not compromise on audio quality, offering a listening experience that is on par with much larger and more complex systems.

If it’s a battery:
→ Likely a 18650 lithium cell pack or built-in LiPo.
→ Search the number on the battery itself.
