The Purchase

I found a portable battery pack on sale at Lotte World for 11,000 Won. The price was low, likely due to its fixed adapter for Mini-USB / Lightning connections, which will soon become obsolete as USB-C becomes the standard. However, for now, most of my devices still use these connections.

Initial Impressions

I'm pleased with the much larger capacity of 5,000 mAh, especially since I was previously relying on a smaller 2,200 mAh battery pack. I’m not a fan of the massive 10,000 mAh or larger models, so I thought this one would be more than sufficient for my brief trips.

Performance Breakdown
  • →Battery Capacity — 5,000 mAh, which felt like a significant upgrade from my previous 2,200 mAh unit.
  • →Connectivity — Uses fixed adapters for Mini-USB and Lightning, though these are aging standards.
  • →Portability — Compact enough for my preference, avoiding the bulk of 10,000 mAh models.

Update (9/10/18)

Unfortunately, my experience took a turn for the worse. This battery pack has proven to be quite disappointing! Other than a blinking blue light, there’s no indication of how much charge remains. It also doesn’t seem to recharge properly; after a few minutes, it just stops blinking. I found myself needing to reconnect the charging cable repeatedly, and each time it only works for a few minutes before stopping again.

Lesson learned: Avoid buying low-quality products! In hindsight, I regret choosing a cheap option and will be more cautious in the future.
IssueObservation
Status IndicatorOnly a blinking blue light; no capacity gauge

Sony MDR-ZX100 vs ZX-110 vs ZX-310 Series Headphones

Gear Review Budget Audio Face-off: Sony ZX Series Review Comparing the ZX-100, ZX-110, and ZX-310 for your everyday carry ~3 Models ~$10–$20 Price 2.5+ Years Longevity Table of Contents ① Build Quality ② Cost Comparison ③ Sound Quality ④ Overall Value ⑤ Upgrade Path Section I Build Quality The Sony ZX series headphones primarily feature a durable plastic construction. My ZX-100 has lasted over 2½ years, enduring countless tosses into my backpack and car without any issues. However, the lower-end ZX-100 and ZX-110 models have a significant downside: poor-quality earpads.   The Earpad Problem Over time, the earpads on the ZX-100 and ZX-110 disintegrate, leaving vinyl flakes that stick to your hair and ears. The ZX-310 comes with upgraded earpads that don't suffer from this problem — a clear win in the build department. Tip: If your earpads start to flake, it is a sign of material degradation; consider replacing the cushions or upgrading to a model with more durable synthetic lea...

Casio G-Shock - DW5600e vs DW5600ue - EL vs LED

Watch Review · G-Shock The G-Shock Square Evolution DW-5600E vs. DW-5600UE 200m Water Resistance 3 Generations Compared 1987 DW-5600C Debut Table of Contents ① Overview ② The Backlight Battle ③ Comfort Out of the Box ④ The DW-5600C (Vintage) ⑤ The Verdict Overview The Gold Standard, Quietly Updated For decades, the DW-5600E has been the "Gold Standard" for G-Shock squares. It's the watch that replaced the original screw-back models in the 90s and became the definitive tool watch for millions. But recently, Casio quietly updated this legend to the DW-5600UE. I've had both on my wrist recently, and while they look nearly identical at first glance, the differences in daily wear are surprisingly distinct.

MacBook Air 2017 - A1466 - Linux - Project + Install Advice

Linux · Dev Hardware · Field Notes My "New" Linux Laptop 2017 MacBook Air — $120 on eBay, Running Linux Mint $120 Per Unit (eBay) 2× Units Acquired 6–8h Battery Life 2.96 lbs I needed a portable laptop with good battery life and decent specs to write code while outside — mostly small-to-medium Python or ASP.Net projects and a few basic ML models. My HP 2016 i7 is too bulky, the HP i3 is hideous, so I replaced my old Linux laptop with not one but a pair of MacBook Airs picked up on eBay for $120 each. Why two? Originally I got the 256GB MQD42LL/A, and when pricing a 512GB SSD upgrade it was basically the cost of a whole 512GB A1466. Why pay $80 for a drive when $120 gets an entire computer? Eventually I'll get a newer M-series MacBook to fulfill my programming needs — but for $120, this is unreal value. Even after 9 years it looks modern and...
