This Anker power bank has a genius feature that makes it irreplaceable for me, and it's still 20% less!
Briefly

From the built-in display to the onboard USB-C cable that doubles as a carrying strap, this is one of the most intuitive power banks I've tested.
Have you ever been in such a rush that you grabbed a power bank to keep your smartphone from dying, only to find that you forgot to grab a cable for it? No? Just me? Up until recently, that was an issue I constantly experienced. But then came the Anker Nano 30W power bank. It has a 10,000mAh battery capacity, a built-in display that tells you how much power it has, and an ingenious USB-C feature that I can no longer live without.
While MagSafe power banks are now all the rage, if you need to charge anything else, you still need to remember a cable. With the Anker Nano, you have a built-in USB-C cable, along with two USB ports -- one USB-C and one USB-A.
