    This power bank holds a 100% charge for over a month if I don't use it. It charges my phone nearly twice before I have to recharge it. Great for power outages and hiking trips.

    A 20,000mAh power bank is for anyone who needs more power. This is the right choice if you have to charge multiple devices at once, keep a single device running for several days, or power more energy-intensive electronics like a tablet or a compatible laptop.

    Awesome power bank. Purchased for international travel, our devices were never out of battery. It is bulky and heavy but it wasn’t an issue for us.

    I bought this a few months ago. Charged it to 100%. It now reads 100%. It very well made. The only minor negative for was what USB port was for charging. You have read the labels closely.

    Slow charging, slow discharge

    Took it back. Does not support fast charging 2.0. I have an Anker 10000 power bank that is 2 years old that works quicker. Took this one back for an Anker power bank that has same capacity but over twice the price just because it charges so much faster.

    I needed a reliable battery pack that doesn’t break the bank! I took third on a 4-day backpacking trip and was able to keep my phone, headlamps, and other electronics charged up and still had plenty of juice left at the end of the trip. Awesome!

    Pretty bulky, but very handy. It fast charges pretty well, but the charging time is quite long. One of those things you leave plugged in overnight.

    Charges things quickly but takes forever to charge the power bank itself. Good size and over all happy with my purchase.
