Oh, I get it now. My bad. That is pretty impressive.
“% = part/100
‰ = part/1000”
Hopefully, what the specs say are really true and not just some typo…
My ZY1270 (/w BT) is dead with an error code 021. It might be that one of the ADC ICs is toast. If anyone is interested in trying to bring it back to life, PM me. You can send me something thats gathering dust in return if you wish.
Found this nice picture:
I bought 2 QC chargers for my Samsung battery, my only quick charging device. Then I found out Samsung uses their own protocol :\

A lot of chargers support the Samsung protocols (They have more than one).

Hmm it’s the 9V one, I think the ZY1276 calls it Samsung AFC. At least Baseus doesn’t support it.

I have a Samsung S9 myself. I measured the charge rate with a ZY1276 and found I was getting the same results if I swapped chargers for my MacBook Pro charger as well as an Anker 5 port charger with USB C and also an Anker 10000mAH power pack that has QC 3.0. Though an earlier Anker power pack that only supported up to QC 2.0 charged at a lower 5V rate. I know my Samsung S9 uses their own charging protocol but also supports QC 3.0. I am not sure about earlier Samsung models.

Yeah the battery, EB-PG950, came from a weird time supporting only the proprietary protocol but before the standard ones. I realized when there were no QC markings on it. Early Apple products were like this too, remember when chargers had dedicated Apple ports? The iPod Touch 2 only charged on Apple ports and not DCP.
Hello can anyone advise me on what would be best tester for my needs?
1. Support DASH for Oneplus Phone (seems not many testers actually support Dash)
2. Test cable resistance for Micro USB and USB C
3. Test voltage and current being supplied to the phone
4. Test chargers to make sure they are actually charging correctly (I assume this is what PD Triggers are?)
5. Bluetooth would be nice as it makes it easier to read when using in a charger and screen is facing in wrong direction to wall
Also what would be a good load tester for this as I know it’s required for proper cable testing.
Thanks for any advice as I had already tried one and it did not properly support Micro USB so I had to send it back.
1. Yes. It’s quite rare for meters to actually support Dash Charge Passthrough
2. Yes.
3. Yes. Most meters can do this.
4. Yes and no for USB PD triggers unless you want to pay hundreds of dollars. There is a USB load which can trigger protocols like QC 2.0 and 3.0, but not PD, which is the HD35.
5. Yes. It’s very nice.
The UM24C supports everything you asked for, and has inputs for micro-USB and USB-C, although you can only see if Dash Charge works via the main USB port:

It’s a really nice meter, and as you can see, it does support Dash Charge:
The 3,5A current to the phone proves it works with Dash Charge, along with OP3 phone connected to it of course.
Thanks for the advice. Watched reviews and it looks easy to navigate unlike the awful navigation of the AVHzY CT-2 I tried. It was a nightmare for me to get to the screens I wanted to get to and all and I will never pick up another single navigation like that system again.
It appears I will need a load tester for cable resistance testing. What model would you recommend?
RD HD35 - it’s the newest model.

Here’s a review of the HD35:

Other choices:
There is a choice for the HD35+UM24C in the link above that I provided.
It’s a really useful tester, as it can trigger protocols like QC 3.0, and can draw up to 35W of power if the port can output it.
Awesome thanks… Got the tester and load ordered.
BTW, guess what I just found:

A QC 3.0 to VOOC/Dash Charge converter.
Meaning we can now have powerbanks with Dash Charge 
Video review about the YZXStudio ZY1280 from dodge_911:
There is now also several UM25 clones which are several dollars cheaper than the RuiDeng UM25/25C that are selling for the cost of a UM24, but the AliExpress sellers don’t mention if it is the UT25 or UT25C with Bluetooth options:
DIY More UT25/25C
Also there seems to be another new company selling a unit similar to the UM25 I have never seen before selling on Banggood:

I recently bought a J7-c “4-way” USB Digital Tester and I can’t seem to find anything that’ll put out more than .7 amps. Even my wall chargers listed as 2.1A won’t do it (to my iPhone 8) nor will a battery saying 2.1A output.
Do I need a special cord for my iphone to draw 2.1A?
