I’m liking the look of this as well. The somewhat irregular cross-hatch texture on it looks to serve well for grip as well as obscure fingerprints and scuffs/scratches.
Piano black (which Anker used on some of their older power banks) simply doesn’t belong on what would be considered a utilitarian device.
Just a few days ago, I dug out a somewhat older unused 500GB Western Digital My Passport external 2.5" hard drive. The finish on it is piano black…for a portable external hard drive. Question is, do I use it or simply admire the sleek and glossy finish on it?
