Thanks for posting the pic of the inside of the charging dock. As you point out there's nothing electronic in the dock. The charging requirement should be the watch itself. Someone else posted that there might be a fusable link on the little dock circuit board to protect the watch.
The 5V/1A max requirement doesn't really make munch sense. For the source supply it should really be a voltge and a min current.
Current isn't "pushed" from the voltage source. Current is drawn by the device using the power. A power supply can provide "up to" the current listed. A 5v 2a source is just fine providing 5v at 1 amp (or less) if that's what the watch is pullilng. Actually, a computer USB port should only provide 0.5A (500 ma) unless a higer current is negotiated. Even a puck rated for 1A will like be able to provide more current before cutting off the voltage.
A higher voltage is a different story. High voltage can cause problems. Standard USB should always be 5 volts.
A Quickcharge source can provide 9 volts, but that's only after the higher voltage is negotiaged.
An Anker IQ type USB charger will sometimes boost the 5v up a bit to help deal with cable loss when a device is pulling high current. I've seen those types of chargers put out up to 5.2v. I guess that could be a problem if the watch is really picky. It's not unusual for a cheap 5v source to be +/- 5% which would put the source at 4.75 to 5.25.
The watch should really be tolerant of some range on the 5v source.
if Mobvoi is really concerned they could add better voltage protection in the charge puck. This puck claims to have an internal voltage regulator. I don't know if they are telling the truth, but it could be better then the OEM:

P.S: I ordered my TicWatch Pro during the Prime Day sale. I'll have it next week and see how the charging goes. I just can't believe that I can't use the trusty 10 port Anker charger that is already sitting on my kitchen counter.
