The new ZY1280 appears to be the upgrade from the ZY1276 / ZY1276P(Plus?). The ZY1278 appears to just be the USB-C (only) version of the ZY1276.

using Google Translate to translate the marketing blurb for the new meters:

Leader in high-end USB meter! Truly instrument-level accuracy!

!! Safety warning !! This type of tester has multiple input and output ports. All interfaces are connected in parallel. Only one input and one output are allowed to be connected at the same time. Some model testers support high-voltage fast charging. When the high voltage is triggered, there will be high voltage on the input and output ports. Do not connect any equipment with insufficient voltage resistance. Please confirm that the voltage is correct and then access the equipment. This will result in problems including but not limited to burning mobile phones, burning equipment, burning adapters, etc. This shop does not bear any responsibility!
