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.
20mins charging time…. 13hrs battery life playing good audio quality for music and voice calls…. 10meters distance… can be use/pair with virtually all devices (and we tested it by the way)… I bought it in greenhills san juan for 1,500pesos… and some claim 1,100pesos sa iba… oh diba!
