I've been looking for a power bank that supports fast charging of devices, while being able to charge it quickly (so it doesn't take 4 hours or more like the old power banks), has at least 20,000 mAh, and doesn't cost a fortune. The AlzaPower Onyx APW-PBO20CFB met all the parameters, so even though I had no experience with the AlzaPower brand, I took a chance. So far I am satisfied with the power bank and I rate the purchase as a good investment. Hopefully it'll last a few years.

Performance is sufficient and the display with numbers is not missing.
The body is plastic, not metal.
The power marking is on the matt plastic in miniature letters. If airport staff want to check the maximum allowable power, it will be difficult to find out.
