Anker Power Bank(PowerCore 10K),Compact Travel-Ready 10,000mAh Battery Pack with PowerIQ Charging Technology,5V/3A High-Speed Charging for iPhone,iPad,and More (USB-C Input and Output（Black），1pack)

Bought this for an upcoming trip. And it was very handy. It has some weight to it but you don't notice it after awhile. On a full charge, it re-charged my Android multiple times on my 10 day trip. I only had to recharge it once. It wasn't fully dead but just wanted it topped off and back to 100%. Would definitely recommend it to anyone looking for a travel power bank.

Had this for a couple of years now and still works well. Good product

Anker is the only brand our school tech department recommends, so I tend to trust their charging products, and this power bank has been another winner. The 10,000mAh capacity is a great balance between power and portability. It is small enough to toss in a backpack, purse, or carry on without taking up much space, but it has enough juice to keep my devices going when I am away from an outlet. I recently traveled with it and was reminded how nice it is to have a reliable backup battery. It charges devices quickly, holds its charge well, and has been completely dependable. One thing to be aware of: I recently got a new iPhone that uses a USB C charging cable. I grabbed a USB C to USB C cord for this power bank and quickly realized that was not going to work. To use the USB A output on the power bank, I needed a USB A to USB C cable instead. Before you head out on a trip, make sure you have the right cord packed. It also takes a while to fully recharge the power bank itself, so plan ahead if you know you will need it. The upside is that once it is charged, it has enough capacity to charge your phone more than once, which is exactly what I want from a travel power bank. The build quality feels solid, and it is easy to see why Anker has such a good reputation. If you are looking for a compact power bank that is easy to travel with and just works, this is a great choice. Update: I purchased another one and had quite a different experience with shipping. I’ve owned this Anker power bank before (this is my 3rd purchase), and I’ve even gifted it to others because I’ve always trusted it. Unfortunately, this order arrived unusable. ✔ Shipping box: perfect condition ✔ Packaging inside: only a thin plastic bag (unusual for this item) ✘ Power bank: completely cut through and damaged This wasn’t minor damage—it’s fully non-functional. No idea how it happened, but it clearly wasn’t safe to ship in this condition. Very disappointing, especially since I needed it for an upcoming trip this weekend. I’ll be requesting a replacement. Hoping this was a one-off issue, because the product itself has always been reliable in my experience.

Second time buying this, works so well. My last one had the battery bloat after being in humidity/heat and older model. Lasted a long time. Gives my iPhone 2 full charges with battery to spare

I purchased this about 8 months ago and have used it since then with great success. I got a 12" USB-C with it and I use it to charge my phone and a wireless Bluetooth device I have (for my hearing aides) when I'm out and away long enough to drain the batteries. I haven't had to use it three times in a row without recharging, but I think it would. That's at least four days (or more) at my regular use. And since it's almost exactly the size of a phone (and just a little heavier), they sit together nice when charging, and it takes up little space in my pack. Anker-Solix is also a high-quality manufacturer in my experience, and so I feel very good about the quality, durability and lifespan of the battery.
