content: Nowadays, Type-C interface is wildly used for its superior performance; It’s much better than others in terms of interface volume, charging power, transmission speed and ease of use.Recently I got a new Type-C USB tester (TC66C) from RD technology, they produce many kind of USB testers like UM24/Um25/UM34/TC64, they perform well but can be better. So, today I want to introduce it to you because I think it will be a useful tool for many enthusiasts and laboratory workers.OK let’s have look at TC66C, it is compact designed and easy to carry. We can test our device anywhere because it doesn’t take too much space.There are two versions: TC66 and TC66C,the only difference between them is TC66C can communicate with mobile phone by Bluetooth connection while TC66 cannot.Then we can see details of TC66C, just as shown below, TC66C has 8 interfaces and each interface has its function. Compared with other USB testers, it is more powerful. I will introduce some useful functions and you can know more about TC66C.I list these functions and I will introduce them in detail.-6digit voltage and current, resolution is 0.0001V(0.1mV)/ 0.00001A(0.01mA)-Quick charge protocol detection,-PD and other trigger operation,-USB communication for PC software,-Bluetooth communication for IOS app and android APP,-Firmware upgrade,-Two-way measurement,-Independently power supply-Offline storage1.Voltage/Current accuracy comparisonwe can see that Voltage and Current are displayed in six digits, which means the Voltage measurement resolution is improved to 0.0001V (0.1mV), and Current measurement resolution is improved to 0.00001A (0.01mA). I think it will be suitable for enthusiasts or mad scientists.2.quick charge protocol detectionWe know that many electronic products has quick charge mode: Samsung AFC quick charge, Huawei FCP/SCP quick charge, PD quick charge etc. These quick charge modes can be detected by TC66C; Several different chargers are tested as shown below. We can see two colors on the screen, green options indicate supported protocols, red options indicate unsupported protocols.3.PD TriggerTC66C can test the maximum power of PD charger, so that we can know the quality of our charger.4.Two-way measurementTC66C allows current flow passing in two directions(from male port to female port/from female port to male port) so we won’t be afraid that the tester might be burned if we insert the wrong interface.5.USB communication for PC softwareC66C supports PC software communication, after being connected to PC by Micro-USB cable, we can view data on PC software, it can record curve when mobile phone is charging. (PC system must be Win7 or above, TC66 and TC66C can use the micro USB to connect computer)6.Bluetooth communication for mobile phoneWe can also use mobile phone to view data or operate. TC66C can be connected to APP by Bluetooth. That is so convenient for me. (Android system must be Android 5.0 or above, iPhone must be IOS 8.0 or above)7. Offline storageSometimes we will be busy and we do not have time to record data, we can use offline storage function; data information will be recorded on TC66C and be exported to PC software when connected to PC.8.Firmware upgradeWhen there is a new firmware, the tester will remind you to upgrade the firmware. So we can use new functions.9.Independently power supplyTC66C can be Independently charged so that it won’t consume the voltage and current of the device under test.In short, I am satisfied with TC66C, thanks for reading.Products link:LINK REMOVEDThis is home page:LINK REMOVED

content: Unexpectedly decent English on that post.. I wonder why the official marketing material still looks like Google translated, should have put all that effort in there insteadBut yeah, trying to pass as an independent test while having most "photos" being screenshots from the official advertisement video or product page (or modified a bit), thehe... (Let alone the actual text content, but photos are easy to match.)

content: Quote from: maginnovision on March 29, 2019, 08:48:46 amAre you sure you didn't mix resolution vs. accuracy? At least to my eyes the screenshots (stills) seem to indicate the resolution as advertised (though can not be verified from just stills), and looking at the source video seems to show digit changes in that last digit (that is not enough to ensure it 100%, though, it might still skip some values).The accuracy, however, is clearly not in the 6th or even 5th digit. But then again, its specs doesn't make such claims anyway; "voltage: ±(0.05％+10digits at 23℃), current ±(0.1％+20 digits, at 23℃)". So, to my eyes, the screenshots seem to meet those specs.UM34 seems to have 0.2%+1digit and 0.8%+3digits, respectively, so, at least by the specs comparison, TC66 has indeed both better resolution and accuracy.

content: Seems you guys are being a bit hard, even if this is an advert. The post is informative, and interesting, to some degree.How about having a new sub forum for New Product Announcements? That would keep the main subforums clear of this kind of posting for those that want to avoid them, and give a proper place for people who have some new stuff to tell us about it?

content: The problem isn't the content, per se. Even the products themselves (and the models that preceded them) are interesting. The problem is the sneaky and blatant disregard of the forum rules, even after multiple profiles (might be the same person, might not be) have been warned and subsequently banned. RD Tech just refuses to comply.If I were Dave, I'd remove this thread or most of the OP content, not just the links, because they don't deserve even the residual benefit of the information still being here. Again, I wish they'd do things the right way, but they don't seem to want to.
