Agreed. I have a few myself.
anker is solid. where do you place the AW?
Actually, I had never heard of them until last year when I treated myself to an outrageously self-indulgent (but superb) mp3 player, the SP1000 from Astell & Kern.
Despite the mouthwatering price, it did not come with an external charger; I phoned the company where I had bought (or was ordering) the device from, and they checked with A&K, who, in turn, recommended Anker, specifying the actual piece of equipment, and informing me that this is what their own staff used when taking their devices out on demos.
