It certainly looks suspicious, dodge_911. Back when I was searching for the BW-MF8 cables they weren't in stock, and I refused to buy the BW-MF10 (bought an Ugreen instead). Of course I saw in the BW-MF10 Banggood page customers were blablablaing because phones with lightning connectors do not seem to draw that much current. But laws of physics and wire diameter do matter, and connectors can get dirty. Stingy wire diameter? No, thanks. Maybe you should cut that BW-MF10 cable and see what's going on inside. There is a handful of chinese people which still have not learned speaking truth ethics, you know. ;-)
Calculations and laws of physics tell me your results for the BW-MF10 6 feet cable are not possible, at least not if the wire inside is AWG23. Your results may be rigged in this case.
How can I rig my results?
I show how I measure in my videos, exactly because of that reason.
And I'm not good enough in video editing/compositing to fake my results :)
On top of that why would I rig my tests? But you're entitled to your opinion.
I never said you rigged your results. But if you are a reviewer and do not tear down the items you review, how can you guarantee whatever stuff you receive is what it is supposed to be? Nothing more, nothing less. It is physically impossible for a 6 feet cable with 23AWG copper +/- power wire to display such level of performance, that's it. Did Banggood sent you something different? Well, I'd say nearly for sure. Maybe a maked up BW-MF8. Send them a politely :-) related inquiry.
Cheers ^:)

I did videos on the first two, check out my YT channel in my sig. The Xiaomi charger is the same as a ZMI.
And at the moment I'm making a video about the QB815, the 15.000mAh version of that powerbank.
I saw the DTU-CCL01 (USB load tester, similar to ZL1100) mentioned by Angerdan here (and AliExpress is now having a sale till Aug 30, so prices may be 1-3 dollars cheaper for the next few days)
Based on the video demo above, it seems to be similar to the YZXStudio ZL1100, though the screen is not colored (most new meters like to use colored screens… but not really “needed”), what’s more important is we’re not sure of its accuracy and precision yet (need someone with correct test equipment to do that)…
There’s also the DTU-1705 and DTU-1705L USB meters, which seem to have protocol detection features too: http://d-tao.cn/content/?142.html
Looks like the 1705 has more digits (4 decimal places), while the 1705L has 3 decimal places, both models have protocol detection feature, but only the 1705L has the QC/FCP/etc “protocol trigger” feature.
EDIT: I was hoping it also had data output for logging, but I don’t think so… but a datalogger could be easily implemented with an arduino. If it’s a good product I would really like to buy it and mod it to get discharge curves.
I have it in queue, but I need some more equipment before I will review it.
I have ordered a couple QC triggers from China and they will probably arrive soon, it is this model: Test of QC2-QC3 trigger
With wires soldered directly to the circuit board they are good for my testing.
