A Dozen chargers in the lab: apple is okay, but not the best

Hello! I have been inspired by Ken Shirriff to make a writeup of different USB Chargers you might find.

I tested a dozen chargers and i have some interesting opinions on them.

Technology and programming
Mathematics and algorithms
Interesting problems and solutions
Personal projects and experiments

Code Examples

Here’s a simple “Hello, World!” program in Python:

def greet(name):
    print(f"Hello, {name}!")

if __name__ == "__main__":
    greet("World")

Formatting

You can use bold text, italic text, and inline code. Lists work great too:

First item
Second item
Third item

Conclusion

This blog is built with Jekyll and deployed on Netlify. It uses a minimalist design inspired by clean, readable blogs that focus on content over flashy design.

Stay tuned for more posts!
