Test/Review index of all tested usb chargers, any comments?

If the above list does not work, it can be found on my website.

 

Somebody asked for a list of dangerous chargers and the number of tested chargers was not to large to make a total list.

One of the reasons I post the list here is to get comments about what information to include.

And is the skull to dramatic?

 

I do not expect to update this list (At least not much), when finished the updated list will be on my website.

 

I do have about 10 chargers more that will be tested over the next months, this includes some multi port high power, Apple and many other.

 

If somebody would like other chargers to be tested, please post a link to a shop/ebay with shipping to EU. If I have it in queue or some charger that looks like it I will ignore it, but other chargers I will consider. If you have a old original smartphone charger, that you are not using anymore, I might also be interested (I got the HTC and LG that way).

I like the idea with multiple skulls when one is not enough Smile

Thanks for the list!

The skulls are not too dramatic. It’s a good way to easily see when something is dangerous.
Thank you for your work HKJ!

My English isn’t perfect but I’m trying to improve it. If you see something that doesn’t sound right or is just plain wrong, please feel free to point it out! Smile

It’s kinda scary that the majority of them have safety issues.

That is because they are cheap ebay chargers, anything below a few $ fails. More expensive chargers may also fail, but the fail percent is much lower.

The list is going to be very interesting to look at when I am finished with my current queue. I have tested some more and the cheap chargers are again a problem.

If somebody would like other chargers to be tested, please post a link to a shop/ebay with shipping to EU. If I have it in queue or some charger that looks like it I will ignore it, but other chargers I will consider.

Thanks HKJ. I bought a genuine Nillkin adapter based on your review. Without your in depth testing, tear-downs and inspections, most of us would have no idea what to buy to safely and properly recharge our devices. I was surprised how many chargers and adapters are dangerous counterfeits/no-name models that deliver “dirty power” and lousy performance.

Also, thank you for not being a shill by avoiding affiliate links in all of your posts.

I think it's perfect!

But wont maintenance of the list be a pain in the bum? Every time is see a large table, or a some kind of long list, I think about the "iframe feature" (insert media) of the forum. Hmmm ... But that would only make sense if it was hosted/maintained elsewhere

A bit more explanation to the safety rating:

I wanted two or 3 fail levels, the first one being failure at the 5000 volt test, the next one being failure at the 2500 volt test and then there are chargers with very low safety distance or non-safety capacitors. The first one will fail the voltage test, the second one will usual (but not always) fail the 5000 volt test, but usual survive the 2500 volt test. The problem with non-safety capacitors is that a failed capacitor may short and that can be deadly.

This can happen when the phone is charging and you are not touching it, maybe due to a lightning strike a few km away. Next time you touch the phone while charging and you have a solid ground connection will be very bad luck.

My skull ratings means:

1 skull: The charger failed the 5000 volt test or I found something inside it that is a bit doubtful.

2 skulls: The charger failed the 2500 volt test or the capacitor is a non-safety capacitor or I found something serious inside it.

no skulls: The charger may pass a CE test, but I do not have any proof it does.

Checkmark: The charger do pass a CE test, I now this is true because I have seen the test report or I trust the company and know the charger is real (I only trust a few large companies).

Passing a test for use in US is seldom relevant, because most chargers are marked 230VAC, i.e. they can be used in Europe and must live up to the CE regulations. The standard used in US and EU is the same, but the test values and safety distances varies.

Do all browsers accept this redirection?

If nobody has problems I may change the first post to use it.

As I wrote at the start I do not plan to update this thread at regular intervals, but if I can use a Iframe without problems that would fix the update issue.

Wonderful to have this.

I note sometimes the black horizontal line separator is omitted between a couple of items — in one case they look almost identical.

Is that meant to gather 2 items together if that black line is omitted, as being similar?

A header line with “Last Revised Date ____” would help keep people aware it’s not always current.

I know Iframes have some security issues, that’s all I know about them. Don’t know if it’s specific to the user/browser or the web page host or ??
Normally they’re blocked by my personal settings (in NoScript)

No, it must be an issue with your browser. Try another browser and see if it persist.

I do not really like to maintain that and the first post must be exactly the same as the page on my website (Except for some difference in styles).

I take that as a no vote to Iframes.

I’m actually curious how original brand name chargers from Samsung and Apple would perform in your tests.

Appreciate the list and the underlying time/effort you’ve put into keeping us safe. The skulls are good.

I have no idea about the security issues around iframes, but they work for me.

I already have some new Apple chargers, performance looks acceptable to good and I will also expect safety to be good.

If would also like a real Samsung, I expect performance will be about the same as the fake, but safety will be better (It will not be missing the plastic shield).

> missing lines
Yep, peculiarity of either Firefox, or of the default zoom setting I had in Firefox; zooming out makes all the divider lines show.
And default Chrome shows all the divider lines.
It’s just that at some point a single line of pixels gets omitted on my screen. No worries about that.

> Iframe
If the blog host here understands them and can assure us they’re ok here, I can set my security (NoScript) to allow them on this site (or maybe limited to this one topic).

I mention it because someone else was hoping to use them in another thread a few weeks ago, so I guess it’s a general interest tool. No clue where it is or isn’t secure-able, sorry.

From my laptop i tried, firefox, explorer and chrome. All seems to work

From my phone (samsung galaxy s3 - android) i tried both the native browser, and chrome. Both seems to work.

Other than that I have no experience with iframe. I dont' know about the security issues of iframes, but a google search of iframe issues gives a lot of hits on not to use them. So maybe it's not a good idea.

 

If there are any web-programming gurus with iframe experience in here, feel free to chime in Smile

They are coming. I am well ahead with charger testing, but writing and publishing is not going as fast.

No. They are appropriate. Especially since too many people use junk chinese AC devices. Even several people on BLF. I hope the skulls makes people pay more attention. I would like to see the 1, 2 skull ratings added to your reviews as well.

After reading your previous post, I discarded some cheap ones I had ordered. Buying night lights, I found some on Amazon that say UL listed. I am hoping that is sufficient to indicate safety.

Look for items that are sold direct from amazon (not just ships from amazon). Failing that get a major brand and be sure its not mailed direct from china.

maybe a lightning bolt in a no symbol would be less dramatic…but I guess getting fried from unsafe isolation is not a good thing either

thanks for these awesome reviews!

I have changed the first post to use Iframe and if anybody has a problem with it there is a direct link in the second post.

I have also added another cheap charger and there was no surprise, it got:

Many of these cheap chargers a depressing to check, they do not even try to make them safe.

If the ones you give green checkmarks to are available with US plugs from known good sellers, it’d be useful to point those out if anyone can do that.
I’m sure the dangerous ones will be much easier to find (sigh)

I found this at Amazon: OEM HTC USB Travel Charger Adapter U250 / CNR6300 / 79H00095-14M
http://smile.amazon.com/HTC-Charger-Adapter-CNR6300-79H00095-14M/dp/B004...

and lots of people over several years saying it doesn’t work and isn’t from HTC in the reviews, and they’re still selling it

Here, I think, is a real one: http://www.htc.com/us/accessories/#!pid=htc-desire-eye&acc=htc-rapid-cha...

The ones with checkmark will usual be from the big brands, the ones without checkmark will be the cheaper ones that will usual be fine.

One example is Eachine, it looks perfectly fine and I believe that it will pass a CE test (It probably has), but I cannot do the full range of safety tests and therefore I will not  give it a green checkmark.

If anybody has an idea for a symbol to use, please post it. One solution could be a smaller checkmark in brackets: (v)

You could use a green outline checkmark, hollow instead of filled in — I think that’s often enough a way to indicate a somewhat less emphatic approval.

and/or a link to the manufacturer for inquiries about CE or UL certification.
(I know UL marks are supposed to include a unique number that can be looked up because they’re often enough counterfeit marks)

“UL listed” seems to imply that there is a list, which should nowadays be available on line, to look the product up in, to assure that the mark is genuine. But I don’t see the list on the UL Website. I don’t see instructions for checking certification validity on Wikipedia either, though they show a picture of a counterfeit mark, maybe whoever knows the answer should enter it in Wikipedia.
