An unofficial chapter of the popular Dull Men's Club.

https://dullmensclub.com/

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

I am an IT guy and have a lot of USB cables and chargers.

As the world consolidates on the USB-C connector, regardless of what cable is actually used, it becomes more important to verify the specs of a cable and chargers.

Just because they might say USB3 doesn't mean that they are USB3, they might USB2 with USB-C comnectors, or they might be a hybrid solution with a low data rate and a high charge rate.

How do you know?

A real USB cable analyzer costs a shitload of money.

I have three tools that can help me get and idea about what kind of cable or charger.

  1. The USB data lines tester - this tool shows if a USB cable has all pins connected, a quick and dirty test to verify the design of the cable, if not the quallity.
  2. USB Power meter - This is probably the most useful tester you can get for everyday use, it shows the current power draw when connected in series with a carger/powerbank, cable and device, you can verify that a device is actually charging and how fast it is charging. You can verify that a charger is supplying the correct amount of power and even see a diagram of how the charge rate over time.
  3. USB power load tester - This allows me to force test a charger's output, it also tests if the charger can support fast charging protocols like QC or PD, the model linked does not seem to support PD testing, but mine from joy-it.com does.
