    Anker 20,000 mAH is great! Long life , fast charge with digital battery life display. Solid battery and heavy, which I like because that usually means tough. Also has a charging cord attached to the lanyard, no more hunting down charging cables.

    Very nice battery pack for the price! Doesn’t take that long to charge a mobile phone down at 15 percent and still has a lot of power left over to fully charge other devices!!

    I’ve been using the Anker battery pack for a few weeks now, and it’s honestly exceeded expectations. The build quality feels super solid and durable—like it can handle being tossed in a bag without worry. It charges my phone lightning fast, and I’ve been able to get multiple full charges off a single pack. One of my favorite features is the LED power indicator. It’s clear, accurate, and helps me plan ahead. It’s a little heavy, but tahts to be expected with how much capacity it holds. Whether I’m out hiking, traveling, or just stuck in long workdays, this thing keeps me going without reaching for a wall outlet. Definitely a 5-star product. If you're on the fence, just go for it. You won't regret it.

    Great power bank, charges my iPhone 16 pro max to 80% in about 20 mins. And still has plenty of charge left for around another 6 charges of the same iPhone.

    Gives me about 4-5 full charges and has been a lifesaver. It has really fast charging and it also charges pretty quickly. I love the 2 options it has. One is regular charging and the other one is fast charging. I also appreciate that it shows percentage rather than bars since it makes it easier to see how much I have left.
