Just turbo charged my phone for the first time, having bought a 25w charger; its incredibly fast! I was happy with the charging time just using my A7 tablets charger, which is reasonably quick, but the 25w makes it look slow by comparison; its fair to say I am impressed.
On a side note, I collected my free gift of a Smart Tag and Buds Pro today too, so thank you Samsung; I'll unbox them later.
