TC66C-a powerful Type-C USB tester

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!]

another review(Thank you for your support)
[Technology with a type-c connector becomes more and more, so this tester was so necessary for me) with it i can check the capacity of the charge of the superbanks, track the characteristics of the charge technology and output via bluetooth all this on the phone screen, check the wires for conductivity and evaluate the charge protocols. I like the product the ability to trigger quick charging protocols: it is immediately visible that it supports charging and where the sagging occurs. The tester is miniature, which is convenient. The small screen displays many functions of charge, characteristics of current, voltage and capacity. Purchase is satisfied! I advise the seller. Delivery took 9 days. The tester is suitable for everyone who wants to be aware of the quality of the cords used and, most importantly, check the supported protocols in the adapters for lice.]

new review(from Japan)
“Meanwhile, RD TC66C of the new product also supports measurement of USB PD 100W at a low price of $ 24.50, and also supports trigger functions such as USB PD, Quick Charge, and FCP. In addition, it is possible to connect to a USB cable and see the current and voltage with a PC, as well as to confirm with a Bluetooth connection and a smartphone application.”
