A box with mains in on one side and 5 usb output on the other side.



Measurements
  • All outputs are in parallel, but with fuses on each output.
  • Idle power 0.17 watt at 230VAC
  • Idle power 0.1 watt at 120VAC
  • All USB outputs is coded for Apple 2.1A, but uses a chip to automatic switch coding.

Eachine%20PA40W%20%231%20load%20sweep
Eachine%20PA40W%20%233%20load%20sweep
Eachine%20PA40W%20%235%20load%20sweep

Output voltage is stable and the efficiency is around 80%, all the usb outputs looks the same.

Eachine%20PA40W%20load%20sweep

Running all outputs in parallel I can test the full current of the power supply, without to much loss in the cables.
It looks very nice, except for no overload protection. There might be one at a higher current, but if not, I would have destroyed it with the test.
In the tear down it can be seen that there is a small fuse for each output, but it does obvious not trigger at the currents I used for testing.

Eachine%20PA40W%20120VAC%20load%20sweep

120VAC does also works fine.

Eachine%20PA40W%20load%20test

One hour with 8A load is not a problem.
The temperature photos below are taken between 30 minutes and 60 minutes into the 1 hour test.

Temp1616

M1: 54,3°C, M2: 52,5°C, M3: 57,6°C, M4: 62,2°C, HS1: 68,8°C
When comparing this with the tear down it is easy to see that the hottest part is the output rectifiers that is mounted on a heatsink.
The two other warm parts are the trafo and the input heat sink with the main switcher transistor.

Temp1617

M1: 55,5°C, M2: 58,7°C, HS1: 67,3°C

Temp1618

HS1: 58,6°C

Temp1619

HS1: 62,0°C

10ohm

There is not much noise, 15mV rms and 106mVpp. at 0.5A.

0.6ohm

At full power (8A) the noise will only increase a little 16mV rms and 164mVpp.



Tear down

DSC_8871

There was no easy way to open the box, I had to break it open and it was a bit difficult (This is good).

DSC_8872

It looks well designed with fuse and filter on the mains input, a 105°C capacitor and heatsinks.

DSC_8873

There is some interesting details on the circuit board:
Each usb output has a small chip, probably to automatic select the best coding of the port.
The white part marked T1 is a fuse.

DSC_8874

DSC_8875

DSC_8876

DSC_8877

Notice the black paper between the trafo and the heat sink, it is used to improve isolation.

DSC_8878

DSC_8879

The isolation distance is good in this power supply.

Testing the mains input with 2500 volt and 5000 volt between mains and low volt side, did not show any safety problems.



Conclusion

This power supply/charger looks very good, it has lots of power, good isolation between mains and low volt side, stable output voltage with low noise and can charge just about anything.



Notes

The power supply was supplied by Eachine for review.

Thanks for this HKJ – I love these reviews, especially when you destroy them in the tear down at the end. Smile Impressive that it can handle 8A in total, though I think I’ll stick to my Ioncell one that you reviewed some time ago – it’s good enough for my needs.

Thanks HKJ. Has anyone found an alternate supplier as Amazon will not ship to Australia. Google has failed me in my attempts.

This one looks identical to me:

Even cheaper unbranded: http://www.ebay.com/itm/221670457118

It might be that, but it is difficult to say without opening it.

I plan on testing more usb power supplies (At least 10), including some more multichannel high power ones. It will be stand alone reviews like this.

This means that I will be publishing the reviews over a couple of months.

And I did order two of the unbranded ones, one for testing and one for myself if it the other passes the test.

Belkin? Really? Not likely, I’d guess, but quite a variety of these out there now.

Pity nobody makes them with transparent cases so you can see what’s inside, eh?

Belkin-40W-5-Port-PowerIQ-USB-Wall-Charger

And more than 175 if you just search “5-Port USB-Wall-Charger”
price between $10 and $200

It’s a strange world …

It appears Banggood is the official supplier but they are out of stock.

I ordered one from Amazon based on HKJ’s review. (Thanks!) It arrived in four days without premium shipping. It does appear to be identical to the unit pictured in kaiser’s post.

I use it to run my “XTAR VC2” Li-ion charger, which uses USB power and was previously connected to my Apple iPad power supply. The other ports are handy for charging tablets and phones using short USB to Lightning connectors available on eBay.

A great gadget. Thanks for the tip!

That’s interesting: The name on the circuit board pictured is “vinsic”. I’ve bought 2 identical looking units with this brand name (vinsic) some time ago at Amazon.de. The Model No. is VSCW502 and the specs are almost identical to the one above. (smart outputs, 8A…) Nice to know that these prob. will be of the same quality tested and approved as the Eachine above. Compared to other similar multi-output devices I’ve tested (Anker 40W, Tecknet 50W) the Vinsic has a little low output voltage acc. to my measurements (with charger monitors). With 1A load still at 5.02V it drops to 4.92V at 1.8A load. The voltage level of the other brands is a bit higher which can be a good thing in order to gain the max charging rates with USB units.

“BlitzWolf” at BangGood

— the label in the BangGood picture says Manufactured by “Shenzhen Shebel Science and Technology co.LTD”
(note lower case and no space in “co.LTD”)
— the label pictured in the review here (first post) differs in that last bit
(having a comma after the period: “co.,LTD”

Trivial difference, but that’s what we look for to identify fake battery wrappers, so I have to ask.
Same long model number in the two pictures: ZQW121123050805
and ‘oogle finds upwards of 600 hits for that, several different brand names on what’s presumably (one hopes) the same thing.

Just concerned that it’s possible to get the same board with parts left off to save money, as observed on seemingly identical hardware of other sorts.
Who ya gonna trust? Nobody, without verifying.

‘oogling finds a variety of variations, for example:

Quote:
Shen Zhen Shebel technology co. Ltd was established in the year of 2012.

Note the various differences in the output power label too.

and ‘oogle on the model number (above) finds an Amazon model listing a different manuufacturer
“directed by FLOUREON manufactured by Zhengbai”

At least the Model number and manufacturer as well as the rest of the inscription on the side of the box looks identical. It seems like one OEM manufacturer (Shenzen Shebel Science…) sells his products under various brand names, maybe for different markets / world regions.

If it’s the same as in OP then no, it is glued (“There was no easy way to open the box, I had to break it open and it was a bit difficult (This is good).”)
I you are samrt (smart) then keep it in one piece. Wink

Hi HKJ and everybody else, thanks for all the wonderful info!

I have found some more info regarding this interesting charger – Images of the BlitzWolf’s brand internals:

http://img.banggood.com/deals/edm/topic/bigtime150430/bigtimem_18.jpg
http://img.banggood.com/deals/edm/topic/bigtime150430/bigtimem_19.jpg
(Source: https://www.ozbargain.com.au/node/193411)

According to the images it looks identical to what can be seen in HKJ’s teardown.
Furthermore, it seems that at the beginning of the month one could buy this unit from banggood for $15.99 shipped, but right now the coupon no longer works – The cart amount just goes down to 0$ and you cannot proceed with the checkout process. Oh, and they are out of eu plug version as well :_(

If someone manages to buy this one from banggood at the lower rate, please let us know.

Peace,
v0yAgEr.

Banggood teases; they offer the black one at $15.99, briefly — but it goes by so fast you don’t have time to click before the price goes up:

Haha I don’t think so… Looks more like a bug to me.
I have just sent them a message using their chat system about this issue.
Let see what will they say.

In relation to the products being discussed in here, I would really like to have some more info about the Anker’s 40W 5 port direct knock offs.
They all seem to be very similar design-wise, so I assume they are all the same, or very close to be.
I also assume that they are not equal to the Eachine PA40W, as everything similar to that model, has the same shell, and the same model number (and ~10$ higher price tag).
The Anker’s knock offs don’t have those “features”.

This is the original Anker product (not available internationally BTW):
http://www.ianker.com/support-c7-g345.html

Some of the knock offs I have found (some are even branded):

Etcetera, etcetera…

So, if anyone has some experience with them, please share Wink

I own the Anker 5 port 40 watt charger. I only charge my Nexus 7, Moto G, and an iPod Shuffle with it. It works flawlessly and runs cool. I leave it plugged in 24/7.

Thanks for the input.
Even though not professionally tested, I’m sure that the original Anker product is excellent. It comes from a well known brand and has lots of good reviews.
The sad thing about this product is that Anker won’t ship it internationally and therefore I can’t purchase it.
I’m about to buy either the BlitzWolf unit, or one of the Anker direct knock offs, but I need some more info first.
I need the info because my entire idea is to get some high quality product, as I want my phone to last, and me being safe Smile
