TC66C-a powerful Type-C USB tester

Well, there’s not too much you could do to improve your USB meters, since they are already so good.

However, an update to the UM25C with a micro-USB port for auxiliary power would be great, along with firmware updates.

Thank you so much, our usb-tester will be designed based on TC66C, and the functions you said will be added to our USB-A tester :laughing:

I would like if it would save trigger settings between power cycle and automatically it would be applied when power is back on. So for example I can use USB charger as power source for desk LED lamps, audio devices, wifi routers etc.

sorry, we can not accomplish this now, still need time

Display PD power-data objects (PDOs) in the Protocol Detect function of the TC66C. You show the supported voltages already for QC and it would be great to see the information for PD.

It looks like you are already detecting them since Protocol Trigger shows only the supported voltages.

I have an idea for a product, but not for this particular tester.
Since you already have a number of devices that can measure and log current and voltage simultaneously, I’d love one that could be connected to a standard 18650 or AA cell in a charger to measure the performance of the charger. Right now, the cheapest way to do these tests is to buy two logging DMMs and use a custom piece of software to record from both at once, plus you need to make some modifications to ensure the added resistance isn’t too high.

Speaking of ideas for new products, a Li-Ion battery discharging/analyzing rig would also be useful. Most of the regular analyzing chargers only discharge at 0.5A or so.

Can the TC66C be used to tell what PD voltages and currents a laptop with a USB-C PD port can accept/deliver? Or is it only for PD chargers?

Thanks.

No, unless your laptop can provide some feedback.

Strangely, my TC66 will not detect my Lenovo Yoga’s USB C power adapter. Display does not come on at all.

sorry it is only for PD chargers

we will consider it ,maybe add it to new tester in the future

thank you for your advice,we will consider but we need to know how many people need this function first

could you make video or picture to show the problem ?

I’ve been unsuccessful so far in finding a Windows software utility to expose this information :frowning:

we just upload video to show our company ,if you have interest, you can watch,and welcome to our company if you come China Hangzhou

I will buy one if it can discharge/charge at custom current
And i can set number of cycle( for cycle test), and export data to csv file.

Thank you guys. We will do research before we develop our products

we just make a power supply AC 220V-DC yesterday. It is interesting and you can have a look.

NEW TC66C review:

[Excellent tester, comes in the case. Control occurs with 4 buttons. On both sides of the type-c socket, there is also a microusb input. Automatic qc protocol testing menu Long press the right button input to the menu. Left button input under menu It is possible to connect the tc66 tester to the computer. To connect, you will need a microusb cable. Well, the most interesting, you can download the program to your phone, and connect via bluetooth. The tester is excellent, i advise!]
