Widely available, inexpensive, 1 Amp output, single brand name 18650 (LGABB41865), smart USB DCP controller (switches USB coding to match device), 100 lumen flashlight Big Smile (also available in non-flashlight version).

Looks like the same internals might even be available under different names.

Hi HKJ,

I ordererd two of these “Original Kingzone USB wall charger” at Banggood.
http://www.banggood.com/Original-Battery-USB-Wall-Charger-For-KINGZONE-Smartphone-p-960461.html
Allready received them and have them in use but I have my doubts about them.
No brand marks on them or whatsoever and they get pretty warm in my opinion.
If you want to test one of these I am willing to pay for one and get it shipped your way. Smile

My problem just now is a long queue of usb chargers, even if I got it today it would probably be more than 3 months before I publish the review.

I try to publish reviews as fast as possible, but with both battery and charger reviews I cannot do more than one usb charger each week.

I would be interested in reviews of single 18650 battery boxes. Because of there size, I find them very suitable for EDCing. I'm willing to send you some widely available ones if your interested in testing them.

I am very interested in them and I might be able to test/review some in a month or two.

Even if the review queue is quite full, I wonder if you can review some Quick charge 2.0 usb charger.
I wonder what kind of signal is used to trigger the 9V and 12V from the charger.

Here is a cheap one

Here is a more serious one
http://www.aliexpress.com/item/Qualcomm-Certified-Aukey-Quick-Charge-2-0...USB-Desktop-Charging-Station-Wall/32375717507.html
also available on amazon.fr, better chance to get a genuine one
http://www.amazon.fr/s/ref=sr_pg_3?rh=n%3A340858031%2Cp_4%3AAukey&page=3...
Sorry it’s in french but on it don’t appear on amazon.co.uk.

The quick charge is probably using usb power delivery standard, but as long as I cannot use it there is not much point in reviewing adapters with it.

If anybody see some circuit boards than can be used to trigger it, please post a link to where I can get it.

http://www.tomopowerbank.com/blog/tear-down-tomo-v8-4-to-check-if-its-the-best-portable-power-bank-of-yours/

claims “10-protection” and “93% efficiency”.

too many claims!!!

I’m confused whether they actually include batteries – it does say “Battery not including”, but also says “Built in18650 batteries can be replaced …”, so I suspect they aren’t included, which makes it a little expensive, compared to, say, the Xiaomi powerbank.

I also love the “Panasonic or Trustfire? It’s your choice”. Wink

They are fairly accurate, what do you expect better?

I may have misunderstood your tests, but I thought they were less accurate than this other one that you tested too:

It is about the same.

Look at the "Display U" column with current=0 and the "Display A" column when I test with different currents.

Voltage will not be very precise when current is flowing, it will be something between voltage at the input and the output.

The one with the lowest resistance will usual be the winner (That is a very important parameter on these meters).

+1

That one looks like the most advanced i have seen yet.
I hope it is a good one, 8x Sanyo 3500GA should be about as good match as anything out there i think to this powerbank.

I will accept Quick Charge suggestions now, I succeeded in making a box that can trigger it.

I have ordered this one, now but it will be some time before I get around to test it.

Not sure if I missed something but did you already test the blitzwolf 24W 4.8A 2x USB wall charger? (http://www.banggood.com/buy/blitzwolf-24w.html)
