It is similar to AT34 but you will find there are differences between this two devices. It is higher version of AT34. The important improvement is the voltage and current accuracy, now voltage and current are displayed in 5-digit, voltage resolution 0.001V, current resolution 0.0001A. you can see that at the detailed page. As old rule, new products…
And as old rule, new products publishing have lowest price only 4 days, 9.8 usd/piece, if buy more 2 pcs, 8.8 usd/piece.
for now , we don’t have plan on load, we are designing a big display, many button and function power supply

higher voltage is useless, big current is very important , HD35 have 5A current . 35W is enough

Yes, but higher voltage is necessary to test high power USB-C PD sources.
I mean, with a 3A cable at 20V, it goes up to 60W.
At 20V with a 5A cable, that goes up to 100W.
A 100W USB PD 3.0/QC 4.0 load would be large, but very useful for many years to come.

for PD, I will consider

It doesn’t have to support 100W constant because that would be very difficult to cool, but 60W is plenty to test most power supplies and powerbanks.
When the industry is moving towards higher voltage, 5V testing becomes irrelevant because it will be considered slow charging anyways.

High volts and amps loads probably need to be big or have high revving cooling fan.
Yes, probably.
I’d like one even if quite large.

This page covers specs of the RD devices

And this is good for logging data, it can output JSON

One thing I’ve noticed with my RD power meters is that the USB sockets seem to wear out and gives an increased voltage drop
thank you for your share,. it is great . for voltage drop, could you show me ?>
