Both USB-C and Micro-USB ports can fully charge the power bank from 0% to 100% in about 3.5 to 4 hours. For quicker charging, we suggest using the USB‑C port with an 18W or higher adapter. **Q: Is this power bank compatible with the iPhone 17?** A: Yes, absolutely. It works with virtually all Apple and Android phones and tablets, including iPhone 17, 16, 15, 14, 13, 12 and the Samsung Galaxy series, among many others. **Q: Why does my power bank deliver fewer charges than expected?** A: This is normal for any external battery. About 30–40% of capacity is lost to circuit heat and voltage conversion. So a fully charged 15,000mAh power bank delivers about 9,000–10,500mAh to your devices. **Q: Can I take this power bank on an airplane?** A: Yes. With a rated energy of 55.5Wh (under 100Wh), this power bank fully complies with TSA and airline carry-on regulations, so you can bring it onboard with confidence. **Q: Is the power bank not working? Is it unable to charge your phone? Is it unable to recharge itself?** A: 1. Try a different charging method to see if it works properly. 2. Regularly clean the tip of the built-in cable to prevent poor contact due to dirt or oxidation. 3. When using it for the first time, please activate the power bank‘s LED display. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for iPhone Users ⭐⭐⭐⭐⭐ *by C***. on 24 September 2026* Perfect for iPhone users! ⭐⭐⭐⭐⭐ I’m really impressed with this portable charger.

The 2 cables and additional slots for extra cables mean you can charge uore than 2 devices. It recharges quickly and holds its charge well. The digital screen means you can see how much charge is left in the bank and it fits nicely into your pocket. Only thing I would like extra is a way to clip on the cable you use to recharge the bank. I've had to use a velcro strap wrapped around the power bank to keep them together. Otherwise it's a great power bank and I recommend it. ## Frequently Bought Together - CFIAI Portable Charger Power Bank - 20000mAh Fast Charging Portable Battery Pack with Built in USB-C(22.5W) and iOS(20W) Output Cables Compatible with iPhone Android Samsung Phone etc (1 Pack, Blue) - INIU Portable Charger, Slimmest 10000mAh 5V/3A Power Bank, USB C in&out High-Speed Charging Battery Pack, External Phone Powerbank Compatible with iPhone 16 15 14 13 12 Samsung S22 S21 Google iPad etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/731485860-power-bank-fast-charging-15000mah-portable-charger-with-built-in](https://www.desertcart.jp/products/731485860-power-bank-fast-charging-15000mah-portable-charger-with-built-in) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-15*
