there are tons of portable chargers out there on the market but very few of them have a hand crank on the back hi I'm Sarah Mitchell from Cena and this is a first look at the eaton boost turbine 4000 this is a portable charger with a 4000 milliampere hour battery that size battery can charge nearly any modern cell phone and most small tablets eaton calls the boost turbine pocket size but it's too bulky to fit in most pockets you're better off toting it around in a purse or a laptop bag the device itself has a brushed aluminum finish on one end there is a standard USB and micro USB port plus a power button and LED indicator lights to charge a cell phone or tablet you plug the included cable into the USB port if you need to charge the boost turbine you can plug the cable into the micro USB and connect the other end to your computer or a wall outlet adapter which is not included if you press the power button once it will turn the battery on and begin charging whatever gadget is plugged in press and hold the power button and the LED lights will flash showing you how much battery is left in the boost turbine my biggest gripe about the device is that because the power button is recessed below the surface of the outer case it's really hard to press the boost turbines most noticeable feature is its hand crank you need to rotate the crank about one or two revolutions per second to generate enough energy to charge the battery eaton says that one minute of cranking will give you four minutes of talk time given that the boost turbine 4000 is heavy and clunky it's not the most portable gadget charger on the market still with enough power to charge many smart phones and a hand crank to top off the battery the boost turbine is a handy gadget to keep around for when your phone dies and the power goes out you can read my full review on cnet.com i'm sarah Mitra and this has been a first look at the eaton boost turbine 4000 you
