Rhythm has just launched an innovative gadget in Japan called the Crankspeaker. This all-in-one device is packed with features, making it a must-have for tech enthusiasts and anyone looking for a reliable emergency tool.
The Crankspeaker functions as a hand-crank charger, powerbank, Bluetooth speaker, area light, flashlight, clock, and FM radio. Its 4,000 mAh battery can be recharged manually during power outages, though it also supports USB Type-C charging. Once fully charged, it can run the radio for up to 44 hours, the flashlight for 50 hours, and the area light for an impressive 266 hours.
A single minute of cranking adds about 5.1 minutes to the radio runtime, 5.6 minutes to the flashlight, and 30 minutes to the area light. When it comes to boosting your phone, that same minute of cranking provides 2 minutes of talk time or 30 minutes of standby.
For audio, the Crankspeaker features a 45 mm driver and a passive radiator, playing sound from Bluetooth 5.3 connections or its built-in FM radio. The top LCD panel shows the radio station or time, along with the battery level. You’ll find handy side buttons to control everything, including the flashlight settings (95 lumens high, 20 lumens low) and the area light (20 lumens high, 2 lumens low). There’s also a USB Type-A port for charging other devices.
Designed to withstand various conditions, the Crankspeaker is IP44-rated, measuring 195 x 72 x 78 mm and weighing just 450 g. It’s available in stylish black and light grey, priced at approximately $110.
For those in the U.S. interested in similar technology, a comparable hand-crank radio with a built-in solar panel, flashlight, and powerbank might be worth exploring. This dynamic product from Rhythm certainly combines utility with innovation, making it an excellent choice for both everyday use and emergency preparedness.
