Mophie Powerstation Plus USB-C XXL vs. Anker Powercore Plus USB-C 26,800

Hi. Looking for a good power bank for MacBook Pro 16-inch, 2019 model. I see people loving the Anker PowerCore Plus USB-C 26,800, 45-watt, though Apple Store only sells the Mophie Powerstation Plus USB-C XXL. The Anker model gets a lot more reviews on Amazon, and the reviews are great. But should I stick with a model that's actually sold on the Apple site?
