iPhone 14 ケース - バッテリーフォンケース - Casebus クラシック バッテリーフォンケース、ポータブル充電ケース、有線ヘッドホン対応、超薄型ポータブル充電バッテリーパック - TARZAN - Casebus

The headphone jack passthrough is a lifesaver—I can charge and listen on my commute without any adapters. It's noticeably slim for a battery case, yet it still gives me a full extra charge by the afternoon.

I was worried the extra battery would make the phone bulky, but it's actually impressively slim and adds a full charge without adding too much weight. The built-in port for wired headphones is a nice touch, though I mainly use it for the portable charging.

The wired headphone support was the deciding factor for me, and it works flawlessly with my iPhone 14 while the case charges. It's noticeably slimmer than I thought a battery case could be, and I get a solid extra day of use before needing to plug in.
