Product image shows glossy piano black finish when in fact it is a little matte and has scratches all over straight from packaging. Build quality is ok and tolerances appear tight. However, product emits a high pitch frequency when in use that is just enough to be annoying in a room that is absolutely quiet.
I bought this to fast charge my Xiaomi Powerbank Pro 3 and Surface Pro 4. It works fine on the powerbank but it does not reliably charge the Surface. Sometimes it says 'Plugged in but not charging'. Also, its 45W total so using the USB-A ports will drop the charge rate on the USB-C port.
I ended up buying the Cygnett one with 1x USB-A (12W) and 1x USB-C (45W) and it is seriously awesome.
