    Anker by far is the best portable power charger to purchase. We have a total of 4 and wherever we go we know for sure we will never run out of power to charge our devices! A must get!

    I bought this battery pack to take on vacation to Europe. It was a life saver to keep my phone charged. The reason I gave it 3 stars is because this takes at least 8 hours to fully charge plus, its not as portable as smaller versions. Fully charged I can charge my phone multiple times.

    I bought this for my son, cause his phone was dying when he was away at competitions. When his phone was out of power he plugged it in and was able to get ahold of me without a problem.

    Hurricane season is coming and I wanted to be prepared with a charging port type of item. The price was comparable. I've already tested this product and it is a fast charge which was nice.

    I’ve been looking for a really good portable to take on vacations and parties and I’m glad I bought this one. The ones I’ve gotten off amazon didn’t last long but this is great!

    I can’t even tell you how long it takes to run this down. It’s always had plenty of energy to charge my phone throughout an entire weekend or trip. It’s a little heavy, but worth it.

    Not the one that you keep in your back pocket, but it's nice to charge a few devices and still have juice in it. Well done, does not have a cheap look and works well.
