電池手機殼 - Casebus 經典電池手機殼，可攜式充電殼，支援有線耳機，超薄可攜式可充電電池組充電 - TARZAN - Casebus

I’ve been using it daily for two weeks and the wired headphone cutout is a lifesaver—no dongle juggling anymore. It charges my phone about 80% before the case itself dies, and the whole thing still slides into my jeans pocket without bulging.

The slim profile surprised me—it adds barely any bulk to my pocket while doubling my battery life on long commutes. Charges my phone from 20% to full in about an hour and a half, and the wired headphone cutout works flawlessly with my earbuds.

The headphone passthrough is the reason I bought this and it works perfectly—no awkward adapters dangling while I charge. It’s slim enough that my phone still slips into my pocket, and the extra battery gets me through a full day of navigation and streaming easily.
