Review request for HKJ [USB Power Devices]

Is ripple testing something that look like this?

it’s looklike that, but an oscilloscope would be better to capture some peak

XTAR USB probe
“XTAR USB probe is specially designed by XTAR engineers, with good conductivity, perfectly connected to DRAGON VP4 Plus for testing voltage and internal resistance of battery”
http://www.xtar.cc/products_detail/productId=164.html

I did look a bit at them in my Dragon review. They do improve IR measurement significantly because some wire and connection resistance is eliminated, but they are not perfect. The probes for YR1030 & YR1035 eliminates all connection and contact resistance.

It only works with the VP4 Plus Dragon and HKJ already tested it here:

How do you know they don’t work with other USB power meters?

From what I see they are just passive probes.

Yes, so they can be used with any USB Voltmeter. But only in the voltage range of the voltmeter.
Like the YZXStudio ZY1263.

No, the connections in the sb connector do not fit.

Generally I like your suggestions, but there is one problem and that is money. I use a few 100$ (It is that high) each month on stuff to review and that is acceptable for me, but a lot of our suggestions would basically drain my budget for a few items (A month is nearly 31 days and I publish a review most days). If you want to pay for the item I would gladly review it, but when I have to pay for it, the number of your suggestion that get reviewed is rather low. I am sorry about that , but I do not have unlimited funds (your suggestions are usual very interesting).

On another note: I do seldom ask manufactures about review items, I do not like to beg for anything (That may be silly, but it is how I have learned to live), but if a dealer/manufacturer ask me about reviewing a item I will usual say yes (As long as it is on my review list).

That charger probably is an OEM charger, seen that design many times:

If you need funds to review this charger, I’m willing to help. There is a shortage of good higher wattage multi port USB/USB-C chargers and I’ve rarely seen good (technical) reviews.

I have been a bit quite when people is suggesting USB-C PD type chargers, mostly because I could not test them. This has been fixed now and I can run my usual test on all the supported voltages in a charger. The last couple of days I have been testing a few.
I have also added a Paypal account to info@lygte-info.dk if anybody what to help me pay for some of the stuff I test. I cannot promise that any specific request is honored, but I will try.

Have you tested any chargers with MTK (Mediathek Pump Express )?

I do not believe so. Maybe one or two support it in the auto coding, but I have not tested it.

How about the Xiaomi CDQOM06 ?

The review is written, but I do not know when I will publish it. The type number I have is CDQ06ZM

Great to know!
I’d just find some teardown pictures from another site:

HKJ, can you give us a bottom line thumbs up/thumbs down on that Xiaomi charger?
