    Charges extreme fast! Make sure to use a wall outlet at least 2.4 and up, I bought the Anker 2 port to charge the battery.

    Bought it for a trip to Europe. Heavier than I'd prefer to lug around but it's nice having the security of knowing you're not going to run out of power for your numerous devices you rely on. Quick charge charges faster than a wall outlet.
