How Much Cranking Does It Actually Take to Power a Dead Radio?

How long would it really take to crank-charge a dead emergency radio? I built a machine to find out — and the results blew me away. When the power went out during a storm, I realized I might be relying a little too much on my emergency radio’s battery. That got me thinking… What if it was completely dead? No solar. No USB. Just the hand crank. In this video, I built a motorized cranking rig to simulate manually charging a survival radio and tracked how long it would take before the radio would actually power on. You’ll be surprised how long it took — and what that means for real-world preparedness. If you’re into emergency radios, off-grid power, ham radio, or survival gear testing, this one’s for you. 🔦 Want the radio I tested? Grab the Raddy SL10 here: https://www.radioddity.com/products/r...
