# Emergency Audio Speaker Hubs Crankspeaker Blends Various Functions with Hand Crank Backup By Amy Duong | Published 2025-08-10 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/crankspeaker References: [item.rakuten.co.jp](https://item.rakuten.co.jp/rhythm-official/9yya50h/)  The Crankspeaker is a multipurpose gadget from Japan designed for resilience and versatility. It combines a [Bluetooth speaker](https://www.trendhunter.com/trends/portable-bluetooth-speaker1), area light, LED flashlight, FM radio, clock, and power bank, all compacted into a single [waterproof and IP44-rated cylindrical device](https://www.trendhunter.com/trends/jbl-grip). Its standout feature is a [hand crank](https://www.trendhunter.com/trends/4rq002003) housed at the base, allowing it to operate even when electrical power is unavailable. Powered by a 4,000 mAh battery that charges via USB-C or manual crank, it measures just 7.7 × 2.8 × 3.1 inches and weighs around 450 g. A 45 mm driver delivers clear audio, while its dual-end lights offer up to 95 lumens for the flashlight and 20 lumens for ambient illumination. A built-in display shows time, alarm, battery level, and radio frequency. The Crankspeaker offers up to 44 hours of audio, nearly 50 hours of flashlight, or more than a day of ambient light—and a minute of cranking can yield enough emergency power for calls, music, or illumination.
