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.
Bad day, my faithful YZXStudio 1270 has seen his display crushed. It is serviceable ? If so where to find a replacement screen, or who could repair it ?
I bought the model with USB-A + USB-C from Aliexpress, the model is “Baseus BS-C20C” and is written on the housing.
The issue is: when doing protocol detection everything goes on, until it reaches HUAWEI SCP where your meter powers off and turns on again. Could you check what is happening?
If I connect first a Samsung S10 phone to one of the ports, then the TC66C doesn’t reset but then the protocol results are not the same, maybe the ports of the car charger are not independent?

it is Baseus products problem,his charge is bad , he did not use standard charge protocol and use the third part protcol and miss something
at our product page , we write”our products are not compatibility with baseus product”, because his quality is not good, although they sell well, Ugreen charge don’t have any problem
for this problem , we have 2 solutions
1, in fact we already solves this bug , and you can connect PC software to update firmware , it will work
2, you can use micro power to power on , it will not show this problem
Baseus PD car chargers are trash and DANGEROUS. I bought two of the 30W PD + USB A on sale and both failed safety and functionality tests.
The problem you’re describing is mainly because the charger only works in BUCK mode, which is not specified anywhere so in order to achieve 45W output which is 15V3A you must have it connected in a 24V vehicle. Charger is unable to output above 9V and will restart when such voltage is requested.
Secondly the USB A and usb C port are not well isolated for “dumb” usb devices. Normally when you connect a 9V and a 5V device simultaneously the charger must restart to provide 5V on both ends in case it can’t provide both 9V and 5V at the same time, however with the baseus car charger it will simply provide whatever voltage it’s on the C side as long as the A port device isn’t requesting any specific voltage.
In order to perform the above test I used iPhone X with fast charge cable and a cheap lantern that I quite liked on the other end and the instant 9V charging via micro USB blew the resistors. $10 lantern lost because of a $5 charger.
I like that Baseus charger because displays the voltage of the car, the voltage being outputted and the amperage being outputted.
I have used TC66C on a 24V car and has the same issue, it’s not the voltage that makes TC66C reset when doing PROTOCOL DETECTION.
Ok did some more tests and this is what I’ve found:
- TC66C Firmware upgraded from 1.13 to 1.14
- Now if I connect the TC66C directly to the C port of the Baseus your meter doesn’t turn on: Baseus <-> TC66C
— However if I use C to A and A to C adapters in the middle then it turns on: Baseus<USB C to A<>USB A to C<->TC66C. Why is this difference happening, is that the adapters modify something in the middle?
- If I connect the TC66C to the A port on the Baseus I need one A to C adapter and turns on again without load.
PROTOCOL DETECTION detects everything as green when connected to C port on the Baseus and battery is 24V. If I connect to A port it’s the same result but TYPE-C PC is red instead.
