iPhone 17 Pro Max Battery Case 12000mAh – CarPlay Wireless

Power That Never Quits: The 12000mAh Battery Case Built for Your iPhone 17 Pro MaxYour iPhone 17 Pro Max is the most capable phone Apple has ever shipped — a 6.9-inch powerhouse for navigation, streaming, hotspotting, and shooting ProRes video. The problem is that heavy days drain even its big internal battery before dinner. This battery case solves that with a massive 12,000mAh cell wrapped in a one-piece protective shell engineered exclusively for the iPhone 17 Pro Max (6.9 inch). No cables dangling from your pocket, no power bank to forget at home: snap your phone in once and carry roughly double your daily battery everywhere you go, with Qi wireless charging, CarPlay support, and full corner-and-side drop protection built in. It is a case and a charger in one — and it only fits the 17 Pro Max, so the buttons, speakers, cameras, and USB-C port line up perfectly. 10 Key Features 12,000mAh High-Capacity Battery – Premium-grade cells add 100%+ extra runtime, roughly doubling the daily use time of your iPhone 17 Pro Max. One-Piece Snap-In Design – Flexible rubber top bends open so the phone drops in and out in seconds; no two-piece frames to lose. Qi Wireless Charging Support – This upgraded version recharges on standard Qi pads, so you can top up without ever plugging in. Full CarPlay Compatibility – 100% support for CarPlay, car chargers, and wireless charging — your commute setup keeps working exactly as before. Smart Charging Chip – Phone charges first when you plug in, then the case; charging stops automatically at 100% to protect battery health. 4-LED Power Indicator – Press the button and read remaining case power at a glance: 0–25%–50%–75%–100%. 360° Edge and Corner Protection – Raised bezels and shock-absorbing polycarbonate + rubber construction guard against drops, scratches, and daily wear. Certified Safe – CE, FCC, and RoHS certified with overheat, overcharge, short-circuit, and discharge protection. 1,000 Recharge Cycles – The case itself is rated for up to 1,000 recharges, built for years of daily duty. Free Tempered Glass Included – A tempered glass screen protector, charging cable, and user manual come in the box. Materials & SpecificationsThe shell is molded from impact-resistant polycarbonate with a soft rubber flex-top for easy installation and a grippy, ergonomic hold. Battery capacity is 12,000mAh with 5V/1A (5W) wired input and 5V/1A (5W) wired output, plus Qi wireless charging support — typical Qi pads deliver up to 15 W to compatible phones, and this case lets you charge on them without removal. The 4-LED indicator reports charge in 25% steps, and the smart chip manages pass-through priority (phone first, case second). Added weight is approximately 9.5 oz (270 g) and added back thickness approximately 6 mm — both estimated, as the listing does not publish official figures; that is the normal trade-off for a battery this large. Fitment is exclusive to the iPhone 17 Pro Max (6.9 inch).

The Festival-Goer: Twelve hours of photos, videos, and group chats on a crowded network destroys a battery; the extra 12,000mAh means you close out the headliner still above 50%. The Field Technician: Job-site photos, work orders, and hotspot duty for a laptop — heavy drain all shift, with raised bezels protecting the phone from ladder-height fumbles. The Traveler: Certified portable and plane-friendly, it turns a long-haul layover marathon of movies and maps into a non-event. One less charger to dig out at security. The On-Call Professional: Nurses, realtors, and dispatchers who simply cannot let the phone die — press the button, check the four LEDs, and relax. Features & Benefits at a Glance Feature Benefit 12,000mAh battery Roughly doubles iPhone 17 Pro Max daily runtime Qi wireless charging Top up case and phone on any Qi pad — no cables CarPlay support Commute setup works unchanged, charging included Smart charging chip Phone charges first; auto-stop at 100% protects battery health 4-LED indicator Exact case power readout in 25% steps Polycarbonate + rubber shell 360° drop, scratch, and impact protection One-piece flex-top design Install or remove the phone in seconds CE / FCC / RoHS certified Overheat, overcharge, and short-circuit protection 1,000 recharge cycles Years of dependable daily service Included tempered glass Front protection out of the box at no extra cost Installation Guide1. Charge the case fully before first use — plug the included cable into the case's USB-C port and wait until all four LEDs glow solid. 2. Remove any existing case from your iPhone 17 Pro Max and wipe the phone clean. 3. Gently bend back the soft rubber top edge of the battery case and slide the bottom of the phone into the lower cradle, seating the connector firmly. 4. Ease the top of the phone down until the flexible rim snaps over it; check that buttons, speakers, and camera cutouts align. 5. Apply the included tempered glass screen protector if you have not already. 6. Press the power button on the case once to start charging your phone; press again to stop. 7. To check remaining case power at any time, tap the button and count the LEDs. TroubleshootingCase will not charge the phone: Press and hold the power button for 3 seconds; if LEDs are dark, recharge the case itself first — a fully drained case needs several minutes before output resumes. Wireless pad not detecting the case: Center the case on the Qi pad and remove magnetic mounts or metal plates between them; thick pads with raised edges may need repositioning. Phone charges slowly: 5V/1A output is steady trickle-style charging by design — for the fastest top-up, charge the phone directly and let the case handle field emergencies. CarPlay not connecting: Use a data-rated USB-C cable (the included cable works) and reseat the phone so the case connector sits fully in the port. Case feels warm while charging: Mild warmth is normal during simultaneous phone + case charging; the smart chip throttles to stay safe, but keep it out of direct sun and remove thick pocket lint from the port. Frequently Asked Questions1. Which phone does this case fit? Only the iPhone 17 Pro Max (6.9 inch). It does NOT fit the iPhone 17, iPhone 17 Pro (6.3 inch), iPhone Air, iPhone 16 Pro Max, or iPhone 15 Pro Max — the cutouts and connector will not align on any other model. 2. How much extra battery do I really get? The cell is 12,000mAh nominal. After conversion losses, expect roughly 1 to 1.5 full recharges of the 17 Pro Max — about 100%+ added runtime, or roughly double a normal day. 3. Does it support wireless charging? Yes — this upgraded version charges on standard Qi pads (typical pads output up to 15 W to compatible devices; the case manages safe intake). You can charge without removing the case. 4. Does CarPlay still work? Yes, 100% — wired CarPlay, car chargers, and wireless charging are all supported through the case. 5. How fast does it charge the phone? Output is 5V/1A (5W) — steady background charging designed to keep you topped up through the day rather than fast-charge from zero. 6. How do I know how much power the case has? Four LED indicators show 0–25%–50%–75%–100% at the press of the power button. 7. What happens when my phone hits 100%? The smart chip stops charging automatically to protect long-term battery health. When you plug in a cable, the phone charges first, then the case. 8. How protective is it? The polycarbonate + rubber shell covers all corners and sides with raised bezels around screen and cameras. We estimate survivable drops of approximately 6 ft (1.8 m) onto flat surfaces — an estimate, as no official drop rating is published. The screen itself is covered by the included tempered glass. 9. How much bulk does it add? Approximately 9.5 oz (270 g) and about 6 mm of back thickness — both estimated. A 12,000mAh battery has real mass; that is the trade for two days of power. 10. Can I take it on a plane? Yes — 12,000mAh (~44Wh) is under the 100Wh airline carry-on limit, and the case is CE, FCC, and RoHS certified. Carry it in the cabin, not checked baggage. 11. How many times can the case itself be recharged? It is rated for up to 1,000 recharge cycles. 12. What comes in the box? The battery case, a tempered glass screen protector, a charging cable, and a user manual. 13. How fast is shipping?
