    Try hard resetting them or using an adaptor with a higher output.

    I use QC 2.0 certified rated charges for mine and they charge in 4-5 hours. You can get a USB port power meter like this one:-

    to see what power is going into or coming from them.

    DOn't charge a power bank with your laptop.
    Don't use an iphone AC adapter to charge a power bank.

    Buy a Samsung Note 8/S8 fast charging adapter or any adapter capable of at least 2.0 amps of current @ 5V. That's what I use.

    I use iPad chargers and it takes 4-5 hours to fully recharge.
