All things considered, not surprised to see these hand-powered backup battery devices are on backorder at the moment. They're a great idea for an emergency preparation kit for times when your cell phone may become your life line after power and communication lines are down. The BoostTurbine2000 will provide enough power for a 30 second call or a few text messages (depending upon how fast you text) with a minute of hand cranking. And when fully charged ahead of time, the unit can charge up a smartphone completely with its rechargeable 2000mAH lithium-ion battery.
