Review request for HKJ [USB Power Devices]

Is this like a US only thing?

I am working on that one. I used it to check that my box could trigger the different voltages.

It will probably be some time before I publish the review, I do have many older reviews in queue.

No, try Amazon, both .de and .co.uk has it

can you please test these cheap power banks ? all are under 5 US $ along with shipping .. i have ordered from them and received them promptly.

maybe nice travelchargers:

I would like to get some of them to review, but it will have to wait until I have publish reviews for some of the power I already have in queue.

I have ordered them but do not expect reviews in the near future.

Not yet available right now, but would make a neat car charger if it’s decent.

Definitely. I am looking on the C1 model and it looks good.

I think this is the unbranded version mentioned in post 4.

Hey HKJ!

Did you ever test one of those “Emergency USB Chargers”?
http://www.aliexpress.com/item/2-x-AA-Battery-Portable-Emergency-Power-Charger-Power-Bank-Usb-For-Iphone-Ipad-Mobile-Phone/32334256250.html?spm=2114.01020208.3.2.Lhz9A0&ws_ab_test=201556_7,201527_4_71_72_73_74_75,201409_2

I need a very small and light charger for my MP3 Player, so I thought about these.

Not that model, but another 2xAA model: http://lygte-info.dk/review/Review%20Charger%20Danae%20DUO%209000%20UK.html

The energy in 2xAA is not very much, a single 18650 has the energy of nearly 4xAA.

OK, thanks
Then I will use a cheapo 18650 type
Thanks!

I’m sure you really don’t want to try this one out

But people should be aware it exists.

From the comments there:

Very few connectors are protected against that type of vandalism.

My BlitzWolf™ 4.8A 24W Dual USB Travel Wall US Charger just arrived, and while the top port has a steady 5.13/5.14 volts, the bottom port differs greatly as I touch my USB tester. The bottom port ranges from 4.97v to 5.14v and fluctuates from the plug in position, or touching the tester, (I can’t test the amps), it makes me wonder if there is a glitch in that port, that while it will work, it might indicate an assembly flaw that might cause me problems down the road, or indicate a potential safety problem.

Should I seek replacement for my charger?

The two ports are in parallel, i.e. the only thing that can show different voltages is loose connections. I will not guess if it is in the charger, usb connector or usb tester.

It can’t be the tester, because I can keep switching it from port to port to get the same glitchy results, only on the bottom plug.

A loose connection on the bottom port sounds like a problem, and that I need to ask for replacement.

By the way, are the blue lights for the two plugs, supposed to look different from each other?

first powerbank with quickcharge?

Look like aukey rebranding into blitzwolf

I bought 2 genuine 10,400 Mah xiaomi power banks for recharge samsung tablets on longer flights. But, now all airlines are banning their use in flight :frowning:

Monty

Ah, I see now. So not the first xD but still cool to see the quickcharge function coming to powerbanks.
