Why Your Phone's Fast Charger Slows to a Crawl After 80%, and It's Not a Bug

A fast charger can hit 80% in twenty-five minutes and then take another thirty-five to reach 100%. That's not a slowing charger — it's lithium-ion's CC-CV charging algorithm working exactly as designed.

Why Your Wireless Mouse Lags Next to a USB 3.0 Port, and It's Not the Battery

Why Your USB-C Cable Might Be Secretly Limiting You to 60W or USB 2.0 Speeds, and How to Actually Check

Does Kathmandu's Altitude Actually Affect How Well Your Laptop Cools Itself?

Air at Kathmandu's elevation is roughly 11% less dense than air at sea level, which is a real number server manufacturers build into their cooling specs. For a laptop, it turns out to be almost beside the point.

Does a Dash Cam Actually Help After a Kathmandu Traffic Accident, or Is It Just Peace of Mind?

Does a Tempered Glass Screen Protector Actually Save Your Phone in a Drop, or Just From Scratches?

Can a Small Portable Bluetooth Speaker Actually Produce Real Bass, or Is It All EQ Trickery?

Most small speaker drivers physically roll off below 100-150Hz, no matter what the marketing calls the bass mode. Some of what fills that gap is real engineering, and some of it is just EQ.

Do Wireless Earbuds Actually Block Noise as Well as the Box Claims, or Is Tip Fit Doing the Real Work?

A correctly sized ear tip can block 20-30dB of noise on its own, before any active noise cancellation switches on. The wrong tip size can cost you 10-15dB, more than most ANC upgrades add back.
