Lenovo Smart Clock USB Charging Output

I just picked up a Lenovo Smart Clock and love it so far. However, when I plug my phone into the USB port to charge, my phone says "charging slowly". I used a USB power meter, and it only measured 2.5W (5V/0.5A). I expected it to be at least 5W, especially given the fact that the power supply is a 30W power supply.


Can anyone at Lenovo confirm what the output should be? If anyone else could also test the output to see what they're getting I'd really appreciate it!

Hi @dstaley,


Welcome to the Community,


I need to confirm what is the output but the clock USB does not support fast charge.

Re: Lenovo Smart Clock USB Charging Output

I am also very interested in the output as I have a Ticwatch Pro which must not be charged on anything higher than 1 amp or the charger burns out so I am hoping that it really is only 500ma.
