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)

I got it a few days ago and am working on it, but I do not have much time this week. I hope to publish the review in about two weeks.

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.

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.

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.

Hey HKJ!

Did you ever test one of those “Emergency USB Chargers”?
http://www.aliexpress.com/item/2-x-AA-Battery-Portable-Emergency-Power-C...

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.

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

But people should be aware it exists.

http://alterslash.org/#article-8175385

Quote:
Dark Purple has demonstrated his new device: USB Killer 2.0. When plugged into a computer, the deadly USB draws power from the device itself. With the help of a voltage converter the device’s capacitors are charged to 220V, and it releases a negative electric surge into the USB port. This surge “fries” the USB port and, in the researcher’s demonstration, the motherboard — perhaps not always after the first surge, but the malicious USB device repeats the process until no more power can be drawn.

From the comments there:

Quote:
We recently ran a “security awareness” month at the UNI I work for, giving away free flash keys to students who could show us their phone was secured at least with a password or pattern. They seemed surprised that no one bothered and most people told them they are too lazy to have to swype a pattern to unlock their phones. My suggestion was to custom build some pseudo malware, load it on those flash keys, or a set of flash keys, and leave them around campus. Nothing nefarious would happen to the user who did insert it other than an autorun popup informing them that we could have owned them right there if we wanted.

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?

Well, the rules are that you cannot pack powerbanks into your checked-in luggage. But you can have them in carry-on. We now have to separate them from our carry-on at security inspection points so they can be manually verified as OK.

I guess their use is banned because of the risk of over heating and perhaps catching fire, or just the chance of emitting some nasty fumes. It is OK for a Boeing 787 to use Li batteries in flight, but not for passengers Sad

Interesting list, but some of the more interesting ones are fairly expensive.

The “fast charge” cables should be just normal cables (section-wise) with D+ and D- pins shorted. I got a bunch of them and they were weak as hell, the section of the cable was about 0.1mm and they fell apart in no time.

I can’t seem to find much good info on this TrustFire flashlight that supposedly puts out 500lm and can act as a power bank. I carry an 18650 power bank with a weak LED light (50lm?) every day and I’d love an upgrade in which I can also swap batteries if I desire.
http://smile.amazon.com/TrustFire-Flashlight-Camping-Hunting-Activities/...
Or FastTech’s offering with the 4000 mAh TF battery I probably wouldn’t use much, though I might use the case… https://www.fasttech.com/products/0/10000518/1786800-trustfire-tr-a10-1-....
My question is, whether the output from the USB-B port is going to be any better than 1 amp.


The best signature ever.
