At rexi, we’re all about combining precision with a little bit of fun. So while we craft our power banks, chargers, cables, and earbuds to be sleek and reliable, we also love discovering quirky things about the tech world we live in. Check out these surprising and fun facts about phone accessories!
🔋 The First “Power Bank” Was Invented for… Game Boys?!
Before power banks became must-haves for every smartphone user, DIY techies were creating them for portable gaming devices in the early 2000s. Some of the first homemade power banks were rigged to power Game Boys during long bus rides!

🎧 Headphones Were Once Meant for… The Military
That’s right — the earliest headphones were used by military operators during World War I to listen to coded transmissions. Fast-forward to today, and we’re using earbuds to chill to Spotify or crush workouts at the gym.

🧲 Magnetic Charging Started as Sci-Fi
Magnetic charging seemed like something out of a movie, but now it’s everywhere! The inspiration for MagSafe and similar systems came from sci-fi concepts of energy transfer — and now, your phone clicks satisfyingly into place like magic.

🌎 The World’s Longest Charging Cable Is Over 100 Feet Long
While we don’t recommend it, some brands have experimented with ultra long charging cables — one even reached 103 feet (31 meters)! Talk about charging from across the house.
🧪 Your Charging Cable Has More Tech Than You Think
That slim little cable? It often has built-in chips that regulate voltage, monitor temperature, and even communicate with your phone to keep things safe and fast. It’s smarter than it looks — kind of like your quiet friend who knows 3 languages.
📸 PopSockets Were Created by a Philosophy Professor
PopSockets — the now-iconic grip accessory — were invented by a philosophy professor who glued buttons to the back of his phone to stop his earphones from tangling. Who knew problem-solving could go viral?
⚡ Fast Charging Used to Be Science Fiction
Charging your phone from 0 to 50% in under 30 minutes? Unthinkable a decade ago. Now, with advanced PD and QC protocols (yes, like in rexi products!), it’s becoming the norm.
🌿 Eco-Friendly Accessories Are On The Rise
More brands, including us at rexi, are looking into sustainable materials like recycled aluminum, biodegradable plastics, and even plant-based cable coatings. Tech can be clean and green.
🧠 Final Thought
Phone accessories are more than just “extras” — they’re an essential part of how we connect, create, and live. And hey, the story behind them? Pretty awesome too.
At rexi, we’re READY FOR PRECISION — but we’re also ready for a little fun along the way.
