Hello,

After the Fonken Qc3 test, there is a basic version “Smart 2.4A”
Very inexpensive 3-4 euros.
It would be interesting to have a test

Thanks

I have other Fonker chargers on the way (One review is already written) and now I have also added this to my queue.

:+1: Great Thanks

i posted wrong topic, i hope you take a look in this

I will.

Polaroid PS100 power bank with AC output.

This actually looks pretty cool, I wonder if the refresh rate is high enough to properly test ripple. HKJ will you be buying this to test?

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).
