Have you checked the reliability of the brand? I've had trouble with off brands in the past dying quickly. They work for a few months and then won't take a charge. Since you recommended a brand, I will counter the Anker. Their products have proven reliable and well made. They are a little more expensive, but they do go on daily deals on Amazon as well as cyber monday.
I've done a lot of international travel and have never had a problem with bringing a lithium battery based cell phone charger in my carry-on luggage. Airlines have limits on the number of batteries/devices, stored energy ,and amount of Lithium. For example, some of my airline's limits were: (20 spare batteries, 15 electronic devices , Lithium batteries having greater than 160 W hr or 8 grams of Li are prohibited). Batteries must be properly packed so they can not turn on and / or overheat. The interesting thing is that while my airlines rules said loose batteries, battery packs or power banks are prohibited in checked luggage, they were ok with electronic devices with integrated batteries in checked baggage if it was not possible to carry them on and as long as you follow their rules and meet their requirements. On a trip this past spring, I wanted to bring a set of solar security cameras (new in boxes) on a trip to visit my daughter in Australia. These cameras have internal batteries so I checked my airlines rules and found it was ok to pack them in my checked baggage. Below are the rules from a FAQ that I copied and pasted into this comment from the airline I flew with. Be sure to check the rules with your own airline and be aware that these rules could change from time to time.
"Can I take laptops, tablets, mobile phones or cameras in my checked-in bags?
We recommend packing personal electronic devices in your carry-on bags.
If this isn't possible, you must:
Power down the devices completely. They cannot be left in "Sleep" or "Standby" mode.
Ensure they cannot be accidentally turned on.
Protect them from being crushed or punctured.
Your checked-in electronics count toward your 15 device limit."

I’m doing discharge and recharge cycles every day, so I’ll know more in a few months. But it feels solid right now. We shall see…

It appears to be allowed in carry-on only. But I’ll confirm that later.
I’m planning a flight to Italy soon, and that’s one thing I’m checking on.
I just checked with TSA and it appears to be okay to take on a plane in your carry on luggage.
