What is the current consumption of the meter itself?

The usb meter uses about 16mA and 7mA with display off.

What’s the difference between at34 and at35?

At34 = 4 digits total (ex : 05.01v) AT35 = 5 digits total (ex : 05.011v) There’s no real guarantee the last digits are remotely accurate. So get what’s cheap. Use it. When it burns out (like all cheap electronics) get another one. Done

Does it allow data to pass while using it monitor power to a mobile phone? Like plugged a mobile phone plugged into a pc?

The current can be checked when the mobile phone is connected to the product while in use.

Can usb data pass through? (found my existing usb power meter doesn't.)

Signal cables are straight through, you can use usb data.
