When SHTF and weather is not good… or just out in the woods camping… this duo gives your USB rechargeable devices more juice. Tested these hand-crank and battery pack and both of them can charge my Samsung Note2 and Samsung Tablet. The hand-crank charger can also charge the battery pack with four (4) 2400 mAh rechargeable batteries.
