    Works great, took a little longer to charge up than I thought. Just the right size to carry with you when you leave the house or take a trip out of town.

    False Advertising, NOT 20,000 mah

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    On the front of the packaging, it says with an asterisk the following: "20,000 mAh Built-in Cell Capacity". I wasn't sure what that meant exactly but then I looked on the device itself and sure enough it says the power bank capacity is actually 13,800 mAh. Going to be returning this and cannot recommend it as you are getting less than what you pay for.

    I wound up borrowing my daughter-in-laws portable charger which had half the capacity (12,000) but was also half the size/weight. Much easier in the pocket.
