Review request for HKJ [USB Power Devices]

I found another fancy UPM.

Can't find a real manufacturer name for it, but it comes in two models apparently
WEB-U3SE and WEB-U3MFi. Or WEB- is the brand, I don't know :)
But The MFi model looks like an affordable way to check lightning cables...

I found a link to the first one here : https://www.benl.ebay.be/itm/New-TFT-LCD-USB-Power-Monitor-MFI-ARM-M3-Voltage-Current-Meter-Type-C-USB-PD/382281631130

Also found some more info :
http://www.chongdiantou.com/forum.php?mod=viewthread&tid=53453 for the WEB-U3MFi

http://www.chongdiantou.com/thread-54029-1-1.html for the WEB-U3MFi

http://www.chongdiantou.com/thread-21972-1-1.html for the WEB-U3SE

IIRC, there are 2 ways to check ‘certified’ MFi cables:

  • without connecting any load, the Lightning cable should have around 0.0004A (not sure how much tolerance allowed)
  • when switch to QC2/3 mode, and changing a voltage > 6.xx volts, the Lightning cable will not allow it (something like that, I can’t remember the details where I found it… will check)

So, the MFi likely uses one of the above methods.

The ZY1276 with latest firmware (Oct 2017?) is supposed to also add the MFi-checking feature…

I guess DodgeReviews did a video review of this:

FYI They now got the new UM25 & UM25C version

I have a Lenovo P2 smartphone. It has a very large battery (5100mAh) which is charged very quickly when using the supplied charger (rated at up to 12V - 2A). This phone is sold in Germany and thus the charger supposedly meets all the safety requirements here (GS, TÜV Rheinland).

The phone does not have quick charge, but instead Mediatek Pump Express .

Now the interesting thing is that this charger can be bought cheaply on aliexpress (same model for different phone model from Lenovo called sc-10, mine is called sc-13 and looks the same except for the additional German markings like GS and TÜV).

Interesting with EU in the name for a charger with US/Chinese plug.

I don’t think the Chinese sellers pay too much attention to that kind of stuff.

I found another seller on Aliexpress selling the same model and here somebody wrote that it indeed charges the P2 just as fast as the stock charger.

EDIT: I just noticed that both sellers state that it isn’t available anymore. :frowning:
EDIT2: Here is the actual EU-model, also not available anymore.

hello,

It would be interesting to have a test on this tiny charger :sunglasses: Thanks

:+1: Super :laughing:

I’d like to suggest this USB power tester:
https://www.kickstarter.com/projects/tekt/tektyte-logit-specialised-circuit-testers

That Kickstarter was a couple of years ago.

Yea, now it’s available for preorder. But i wouldn’t pay $160 if i don’t know when and if the shipping take place.

ripple testing...don't know how is realistic....

Aliexpress have a big sale, that means it is the right time to post review ideas for discounted stuff from them.

i have 93 items in my cart on aliexp and usually i buy them evaluating price fluctuation and EUR/USD forex variation.... beware that there are legit sale but many prices are also rised few days before and marked as sale when they just have the normal price, or less discount...sometimes the price is even few cents more than usual discounted price.

This is the lowest i found 38.96 on Aliexp General Sale

My 2 cents

Sound like an invitation for links (;
