AnkerPortable Charger, 20,000mAh Power Bank, Battery Pack with 1 USB-A and 1 USB-C Ports, 15W Max Charging for iPhone 16/15/14/13/12 Series, Samsung Galaxy, and More (Black)

Over 5 years and 3 of these power banks (one is still living) I refuse to buy cheap copies. One of these went the entire 5 years. One failed after 3 years (probably my fault for draining it too far before recharge). One 10k mah one is well over 2 years old already and it hasn't failed yet. This was purchased to replace the 5 year old one. With proper care, this should last me as long as the one it's replacing.Word to the wise for those using lithium power banks (Anker or otherwise). DO NOT drain them completely prior to recharge. These power banks are much like your phone batteries. You can take them only so low before they fail to recharge. And also, no battery will last forever. Like everything else, take care of it and it will give you a long life.

Used for travel in Greece, Italy and London so far. Pack in by purse and use as needed. Lasts a long time and can charge my phone and friend’s phones too. It is larger and heavier than the smaller/less powerful chargers, but doable if you need this amount of charge. It stays charged for a LONG time: put it in storage shelf mid-January, pulled out for next international trip in June (same year) and it was still fully charged.

I love this product. It has worked without a hitch, and I have traveled extensively with it. I can’t charge both my wife’s and my phone is less than three hours.

This charges my devices for 4 times it’s incredible!!! A bit heavy though so watch out it’s not very practical for traveling..

The family affectionately calls this "The Brick," as in "Can I borrow The Brick. My phone is almost dead." I've used it to change a small MacBook Pro and many iPhones. For a portable charger, it has plenty of power. While it isn't light, it is very reliable. It's the center piece of my charging kit that I carry in my backpack where ever we go. My only con is that since it is such a large capacity, it can take awhile to fully change even with a faster USB-C charger.

Why did you pick this product vs others?:Love this charger. Charges quick, holds the charge well, and charges phones several times before needing a charge.

Why did you pick this product vs others?:Great battery. Anker- love their stuff.

It's so good someone decided to steal it from me at work!... It was a little beefy but got the job done and charged all my stuff. Def going to purchase again soon.
