Top 5 Reasons Why O’Jillen Power Bank 10000mAh Is the Best
- At 175g, it's incredibly portable. The 65x75x25mm size and 175g weight make it lighter than most smartphones. A built-in strap lets you hang it on your bag or carry it by finger. One buyer noted, "It's smaller than a credit card and fits right in my pocket."
- 22.5W fast charging powers up smartphones quickly. Using the built-in Type-C cable or Type-C port delivers 22.5W fast charging. Both iPhone 16 Pro and Galaxy S25 Ultra reach full charge in about 60 minutes. When asked if it's safe to charge the power bank with a different fast charger, the seller confirmed, "Yes, that's fine."
- Built-in Type-C and Lightning cables eliminate the need for separate cables. Both Lightning for iPhone users and Type-C for Android users are built-in. The 15cm cable length is perfect for using your phone while charging. One buyer mentioned, "No more packing cables means lighter travel bags."
- It can charge 4 devices at once. With Type-C built-in cable, Lightning built-in cable, USB-C port, and USB-A port, the whole family or group of friends can charge together. As confirmed in product Q&A, "Simultaneous charging supports up to 4 devices," though total output is limited to 15W when multiple outputs are used.

Comparison Analysis
O’Jillen 10000mAh Strengths: The combination of Type-C and Lightning built-in cables, 4-device simultaneous charging, and LED display is its greatest advantage. Few products under 20,000 KRW offer all these features.
Comparison with YINTO PD 20W: YINTO is more compact with its docking-style charging, but has only half the capacity at 5,000mAh. Choose YINTO if ultra-compact portability is your priority; O’Jillen if capacity and features matter more.
Comparison with Anker PowerCore: Anker offers global brand reliability, but lacks built-in cables and has lower 12W output. O’Jillen has the advantage if value for money matters most.

We recommend it - The O’Jillen Power Bank 10000mAh delivers 22.5W fast charging, Type-C/Lightning built-in cables, 4-device simultaneous charging, and LED display at under 20,000 KRW. At 175g ultra-lightweight with 38.5Wh flight-safe capacity, it’s especially suitable for frequent travelers and business people.
Caveats - Laptop charging is not supported, and there’s no low-power mode. Some quality issues (built-in cable connection problems, heat during charging) have been reported, but seller A/S response is swift.
Bottom Line: If you want to charge both iPhones and Android devices without separate cables, and often need to share charging with family or friends, the O’Jillen Power Bank 10000mAh is an excellent choice. Get it via Coupang Rocket Delivery for ₩18,900 KRW.
