Frequently Asked Questions

  • How much does this weigh?

    308g. Consider a good weight for that capacity.

  • Does this include the AC plug to recharge?

    No it doesn't. You have to buy one .. Only usb cable is included.

  • I want to plug Anker into USB wall charger which supplies 2.4A.Then I plug my Samsung Galaxy S4 phone into Anker.Will they both charge simultaneously?

    Yes and no. You will be expending the Anker charge while charging your S4, so the Anker won't be gaining much charge, if at all. In fact, you would be generating heat, losing energy through the cables, and overall slowing down the charging process. You would do better to charge one then the other.
