Review request for HKJ [USB Power Devices]

EDC Gear for Flashlight Carriers USB Power Devices

You can get a very good indication of that from my table: Index of tested and reviewed USB power supplies/chargers

Look at current for a single channel and look at “Standard”.
Standard=Auto and 2.4A for each port is the fastest charging for standard usb voltage.
I cannot do it better than that without testing with a couple of different empty phones and I am not going to do that.

212

Ok thanks :slight_smile:

213

I got my EDB-USB+ today and it is the version with a golden hs+fan even though the ebay listing shows the silver one.

Working fine too.

214

Nice 5>12V Step-Up converters with different plugs:

Please test at least one :)

215

I have tested one: Performance test of 5V to 12V 6W boost converter
The usb input connector was not mounted, but as can be seen it has holes for it.

216

Oh, great!
Thanks :slight_smile:

There are so much reviews on your website…

Can you please tell me if it’s good enough for powering small DSL-Routers like a Fritzbox 4020?
They usually have around 5W.

217

This one is rated for about 0.5A at 12V, but can deliver 1A (For a short time).

218

Found this on heise:

Would be a great addition to your reviews :sunglasses:

219

I do not like that type of devices!

220

At least the Test Shield is for good.

221

When I want to zap something I uses more serious equipment and that would probably also zap the test shield.

But any equipment rated for mains usage must survive this test.

PS: That tester is a bit on the dangerous side.

222

Such a device with a higher discharge current than 3A would be even more interesting.

223

What about this two?

224

I own something like that 6-in-1 thingamajig. Basically it’s 3 loads you can combine : 0,5A, 1A and 2A.
At least that’s what they’re supposed to be, they’re ceramic loads, so it may ‘vary’ a little.
It’s also equipped with a bunch of LED’s on the back, which consume about 0,8A and you can connect 4 more loads/devices to it.
Don’t believe mine has the mini/micro)usb connectors, but otherwise it’s identical…
Back in the day, before I had fancy electronic testers and loads, this is what I used to test stuff. It’s quite old…

225

I might take a look at them.
The problem with usb isolators is that they only support fairly slow speeds.

Please consider to review following devices:

YZXstudio 8th Gen powerbank DS2784

Omnicharge PowerBank

PLX Devices Legion Portable Battery Charger 11000mAh

227

Where can I buy it?

That is a Indiegogo project, I may look at it when I can get it from a shop.

Shipping is $22, that is a bit much for a $40 device.

YZXStudio 8 Power Bank Review (4x18650) - #29 by will34

Shipping on the PLX Legion is a bit more than ususal, but this device has been the first powerbank with OLED. And also multiprocessor (temperature, voltage, current, etc.).
It’s currently in the selling out phase, the black one and the smaller 5.500mAh capacity already sold out.

It’s also availiable on eBay:

There's currently the Vitebo VTB-28 on sale for 24€ instead of 40€ at reichelt:

Also very interesting is the Vitebo VTB-80A with 2(!) microUSB inputs:
