Review request for HKJ [USB Power Devices]

:+1: Always looking forward to seeing your charts and teardowns.

Any plan for a Blitzwolf P3 10000 mAh powerbank?
Someone had problems with it…

I know, I had the same problem and am waiting for a fixed version.

Many thanks for your efforts in reviewing such a lot devices!

Just got mine in, it’s charging now…
Hope this one doesn’t have the issue.

You might want to take a look at this EBD-USB+ load, comes with logging software

Taobao shopfront:
I see the older model on Banggood, not sure where you might be able to buy the latest model with shipping to Europe.

And I’m happy to report it does not have the issue.

I’m running that very load in a discharge test atm :slight_smile:
They can be quite easily had on eBay these days… Just make sure yours does not have a short-circuit :

I have been thinking about that load, the review is here: Test/review of Electronic load ZKE EBD-USB


Awesome, forgot all about checking eBay.

Nice! Thanks for the detailed review.

HKJ, I have a humble request for you when testing chargers. Could you add a chart comparison as to how fast a charger charges a device (at how many amps). Different chargers would have different charge rates and some would be faster/slower.

Data such as max charge amps etc could be nice or time to charge.

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.

Ok thanks :slight_smile:

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.

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

Please test at least one :)

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.

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.

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

Found this on heise:

Would be a great addition to your reviews :sunglasses:

I do not like that type of devices!

At least the Test Shield is for good.
