I - owner of an irrational, constant, fiending hunger for high-performance power banks with unique and clever embellishments... and the absurd collection to back up that claim -am blown-away-impressed by this one. In fact, it takes the crown as my far-and-above favorite - of my current collection and, for its class, of all time. It's so dang nice and I admire it so much that I rarely even use it. I just stand there and look at it, like Cameron's dad in Ferris Bueller's Day Off.Truthfully though, it's the one I reserve for guests or traveling companions. And not my clumsy, meat-fisted dude buddies. This one only gets handled by me and by the current woman I'm trying to impress. It's that special. I'm writing this as I place an order for three more, before they disappear.The fit, the feel, the design of this unit is just exquisite in every part of the experience with it. Every sense is fully pleasured, like... well, I imagine like they are in Cameron's dad's Ferrari California, in that fictional reality. It's in the transparent window, the weight and the feel of the matte finish - the way it feels in your hand...A paragraph just for that, as it needs it. Here, the size and shape are exactly what the hand wants, to feel full, to feel like it's confidently carrying a complete load, comfortably. It could hold this thing all day, and it wants to. Sure, it's not a convenient size or basic shape to carry in your pocket or behind your phone in one hand - it's not meant to be. This isn't about that. If you want simple convenience on the go - if you want utilitarian - you've come to the wrong place, my friend. There are infinite competing options out there for you. This, conversely, is a rare find in that sea of mindlessly (non)designed batteries that are just batteries. This is the kind of gold strike that transparent tech lover dream about - the kind that keeps us dedicated to the hunt.And then it just keeps going, impressing, satisfying, fulfilling. It just don't quit, as the kids... as the kids used to say when I was one.It's in the design-nerd-level colors selected. The feel of the button, and the satisfying snap when you plug into the ports. And the pièce de résistance of all the extras and accoutrements and delightful and thoughtful little luxuries: It's that LED display with amperage and voltage - a feature you never find on a power bank at this price point. And even the size of the little numbers and their brightness and the time it takes for them to disappear - it's all just... magnifique!But MOST importantly, of course: It's the performance.This absolute stunner outperforms every single 22.5-(or less)watt battery pack I have in my extensive collection, with truly fast charging, consistent delivery, and a rare power storage capacity that actually seems to be what the seller claims. A 10,000 mAh-advertised power bank actually holding and delivering 10,000 mAh? Unheard-of, pretty much literally! I've tested it with an ammeter / multimeter, and it actually showed me over 11.5 Ah from full to empty - and this ammeter has always seemed pessimistic and has NEVER shown anywhere near 10 Ah coming out of a bank with that claimed capacity.I wrote this review in an attempt to return some of the joy to the sellers, manufacturers and especially designers of this perfect little portable charger which they have given to me by making this thing a reality in my life. If you're reading this, get one of these right now. Yes, I said one! Because I'm thinking I should probably pull this review pretty quickly, so that I have my own jealously guarded little horde of these to make my own, two or three at a time, for as long as possible. I want that horde - I want as close to the full manufacturing run as possible - all for my obsessed and greedy-with-obsession self. And no, when I own them all, they will not be available for sale.As for now, I'm going to stare, watery eyed, at my single one of these - frequently whipping my head around behind me to see what that noise was that I hopefully just keep imagining - and then hit the hay... with this little deity of mine beside me...at arm's length, wrapped in a cocoon of sterilized and softened raw wool and an outer shell of Kevlar sheathed in a custom-made, triple-locking, tungsten carbide case, of course.
