And I already have it, but have not looked at it yet.

There’s a QC & USB-C DIY powerbank with included LED light:

From what I understand, the type-C is only for input (QC3 input); but not type-C USB Power Delivery. Output looks to be USB-A (I wonder if it supports 2xQC3 output. So far, I don’t know any power bank that supports dual (or more) QC3 outputs (maybe only the YZXStudio DIY powerbank?) I believe Anker or RAVPower (and maybe other “branded” ones) are already starting to release USB-PD powerbanks that support up to 30-watt output…

not sure if it’s the same as the one (8×18650 version instead of 5×18650) reviewed here:

I quote the ebay article describtion:
“Double input ports with Type-C and Micro USB interface. Support charging and discharging simultaneously”

I think that means it supports passthrough charging.
Otherwise the micro-usb would be would be in- and output too.

Hey, i’d buy one of this USB power Switch.
It’s even USB 3.0 Smile

There are also a lot of positive reviews:

Funny thing is that this is the only product of the company (:

I wonder how much it does.
It is easy to switch power with a ordinary switch.
USB 3 cannot be switched with a ordinary switch, it requires a chip or a very special switch (I doubt that is the case).

They write that power and data connections are cutted.
I’d try it with an USB 2.0 Webcam and an USB Voltmeter and it seems to me like that’s correct.

@HKJ any good 6/8 variable output + display powerbank in the queue? I'm looking for Qidian but still open to alternatives...

Omnicharge PowerBank

That is a Indiegogo project, I may look at it when I can get it from a shop.
Now production seems to start in november, so maybe in 2018 some copies hit online shops.

This Xiaomi ZMI 20000 mAh?
https://www.gearbest.com/power-banks/pp_662137.html

It supports QC 3 and USB PD 2.0 protocols. It means you can charge some USB-C notebooks (like Mi Notebook Air or Macbook Pro) or QC powered devices. Seems really good. Price is even better (40€ right now). Would appreciate a review!
Thank you

Here’s a “Big Clive” video teardown of one of those rectangular five-port-USB power supplies (this one labeled “Swees”) that leaked a potentially lethal mains 220v onto the USB side:
https://www.youtube.com/watch?v=3Hdn0MuCK_0

Bad assembly QA — transformer winding insulation had been scraped off during assembly, allowing the transformer to short internally, then the fault had been taped over.

Here’s the Amazon page: https://www.amazon.co.uk/SmartPower-Technology-Raspberry-Readers-Externa...

Looks identical to 5-port power supplies sold under a lot of different names, doesn’t it?

Here’s another description of the thing: https://boingboing.net/2016/04/12/the-worst-gadget-ever-supplies.html

That is “only” a QA problem, not a design problem with the charger.

> not a design problem

Yep. The reviewer made the point that it was well laid out with good components, just poorly or carelessly assembled leaving a gap in the insulation on the transformer winding wires that put mains voltage on the USB side.

When I google ‘USB charger electrocution’ I see a surprising number of reports where the mains power somehow got to a person via a USB cable that should have only been carrying 5 volts.

I’m glad my utility only supplies 110v rather than 220v.

It is not really surprising when you look at some of the cheap chargers, some of them are very bad in safety.

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 Smile
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 :

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 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. Sad
EDIT2: Here is the actual EU-model, also not available anymore.
