    I bought both 5,000 and 30,000 based upon price (vs. my old Anker). The units themselves take forever to charge and are equally slow when you are charging a phone or worse.... a computer. If you are in a power pinch, these are unreliable to get the job done fast. Ditching them 3 weeks after purchase (no $ back from Best Buy). I can't take how poor these function. Going back to Anker at 4X the price.

    No, I would not recommend this to a friend

    Product power is weak and cannot provide power to a wireless phone charger. Completely useless.
