The Eton BoostTurbine4000 Battery Pack with Hand Turbine distinguishes itself from all other battery packs by being the only battery pack that does not require charging from an AC outlet. All you need is some elbow grease as the Eton BoostTurbine4000 comes with a hand crank that allows you to charge up the built-in 4000 mAh battery.

While this all sounds great and very eco-friendly, unfortunately our kinetic to electrical energy conversion technology has not reach a level that allows us to fully charge a smartphone using a hand crank. The hand crank on the Eton BoostTurbine4000 is more for emergency use and as a last resort. Eton claims that one minute on the hand crank generates enough power for 4 mins of talk time but it depends a lot on the phone you are using. Our modern smartphones are very power hungry.

Therefore, the standard method of charging the Eton BoostTurbine4000 is via a power outlet. A fully charged unit should be able to give you about 1 to 2 full charges on your smartphone.

While the hand turbine crank may seem more like a novelty but in an emergency, it could be a matter of life or death. Those who love the outdoors and often find themselves in situations where there is no access to electricity, the Eton BoostTurbine4000 is a worthwhile investment.
