Section I

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.

 

Section II

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.

Section III

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
