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.

Issue	Observation
Status Indicator	Only a blinking blue light; no capacity gauge
Recharging	Intermittent; stops blinking after a few minutes
Reliability	Requires frequent reconnection to maintain power flow

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...
