CS-03 16800mAh 12V Vehicle Car Jump Starter Emergency Power Bank
These car jumper/sub power banks are very interesting, I think they will be really popular. Good call for review.
HKJ, will you be able to test the starting power of these?
Not yet, I am looking for a new electronic load that will be able to do at least 100A at 15 volt, but I have not found one yet. 200A would be better, but they get very large when you want 3000W capability and a 100A test is probably enough to reveal the packs that are too optimistic.
Itech (Cheap (Depends on the eye), works well and my software can handle them directly) do have some, but I cannot find any dealers (Ebay or otherwise).
Supposedly 2.1A output, but divided if both outlets used.
Great!
I do definitely not have time at the moment with 20+ usb chargers in queue.

I purchased this power bank and am curious to how it performs, especially since the smaller ENB banks have received such good reviews. I used it on a hike of the Apalachian Trail along with my Armytek Wizard pro and my Galaxy Note 3.
An all too vague request — if there is any power supply made yet that minimizes vampire drain, I’d sure like to see such things reviewed.
Here’s the news I found a few years ago about a reference design, using a supercapacitor:

A second request — a little essay on when to trash/recycle a power supply.
Specifically — when a wall wart switching power supply is audible, with a buzz/rapid clicking, I’d guess that’s a capacitor breaking down and it’s becoming junk?
What other reasons are there?
(When I give up on electronics, generally I cut off the wire and plug, crack the case, landfull the plastic parts, and recycle the electronic parts.)
I do include information about that in most of my reviews. Most usb power supplies is around 0.25 watt when unloaded, but a few are better.
The noise is not directly a signal about it being old, a new one can also be audible, but the noise pattern will probably change.
The typically old age breakdown is the capacitors loosing capacity, it can be measured, but is a difficult to detect without measuring equipment. The adapter will get hotter and it will probably increase the noise in AM radios.

Might be a good one to test.

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

Thanks for all your work, HKJ.
Hi HKJ,
I ordererd two of these “Original Kingzone USB wall charger” at Banggood.
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. 
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
