Magnetic Wireless Power Bank 5000mAh – Ultra Slim MagSafe

The Ultra Slim Magnetic Power Bank That Disappears Into Your Day

Your iPhone is the command center of your life — navigation, payments, photos, work email, boarding passes. The one thing it cannot do is run forever. This Magnetic Wireless Power Bank packs a genuine 5000mAh (18.5Wh) of high-density lithium-ion power into a body just 0.34 inches thick and 115 grams light — about the same thickness as an iPhone 17 Pro itself. It snaps onto the back of any MagSafe-ready iPhone 12, 13, 14, 15, 16, or 17 series phone with 10N of magnetic grip and starts charging wirelessly the instant it lands. No cables to untangle, no brick in your pocket, no anxiety at 15 percent. This is built exclusively for the MagSafe iPhone generation — if you carry an iPhone 12 or newer, it was made for you.

10 Key Features

• True 5000mAh Capacity – A high-density Li-ion cell delivers a meaningful top-up: roughly a 70–100% boost for most modern iPhones, enough to rescue a full day.
• Ultra Slim 0.34" Profile – Thinner than most wallets, it adds almost nothing to your phone's footprint and slips into any pocket.
• Featherweight 115g Build – About 4 ounces; you will forget it is attached until you need it.
• Snap-On Magnetic Alignment – 10N magnets center the coil perfectly every time, so wireless charging just works — snap and go.
• Qi Wireless Charging – 7.5W cable-free charging through the magnetic connection keeps your screen-up workflow uninterrupted.
• 20W PD Wired Fast Charging – Plug in the included USB-C cable and charge an iPhone 16 Pro to 50% in about 30 minutes.
• 500+ Recharge Cycles – The cell is rated for more than 500 full charges without significant capacity loss — years of daily use.
• NTC Temperature Control – A dedicated thermal chip monitors battery and circuit temperature in real time and throttles output to protect your phone's battery health.
• Full Safety Suite – Overcharge, over-discharge, and short-circuit protection are built in for reliable, worry-free charging.
• Travel Ready – At 18.5Wh, it is far below the 100Wh FAA carry-on limit, so it flies with you anywhere.

Features & Benefits at a Glance

Installation Guide

1. Charge the power bank fully using the included USB-C cable before first use — the LED indicator confirms when it is topped off. 2. Remove any non-MagSafe case from your iPhone; the bank works on bare iPhone 12–17 series phones or through a MagSafe-compatible case. 3. Hold the power bank near the center-back of your iPhone and let the 10N magnets pull it into alignment — you will feel a confident snap. 4. Wireless charging begins automatically; the charging icon appears on your iPhone within a second or two. 5. For maximum speed, plug the USB-C cable from the bank directly into your phone for 20W wired charging. 6. To recharge the bank itself, connect any USB-C PD wall adapter (18W or higher recommended) to its USB-C port.

Troubleshooting

Phone not charging wirelessly: Confirm your iPhone is a 12-series or newer and that any case is MagSafe-compatible; thick or non-magnetic cases block the coil. Magnetic hold feels weak: Remove the case entirely or switch to a true MagSafe case — silicone-only cases without a magnet ring reduce the 10N grip. Bank feels warm while charging: Mild warmth is normal for wireless charging; the NTC chip is actively managing temperature. Charge in shade and remove thick cases to run cooler. Charging stops around 80%: This is intentional battery-health behavior under heat — let things cool and charging resumes. Bank delivers less than a full phone charge: Wireless transfer loses some energy as heat; for the absolute maximum transfer, use the wired 20W USB-C connection instead.

Frequently Asked Questions

1. Which iPhones is this compatible with? iPhone 12, 13, 14, 15, 16, and 17 series — any model with built-in MagSafe. 2. Which phones will NOT work? iPhone 11 and older, iPhone SE models, and all Android phones (including Samsung Galaxy and Google Pixel) lack the magnet array — wireless charging will be unreliable and the unit may overheat. We do not recommend it for any non-MagSafe device. 3. How fast is wireless charging? Qi wireless output is 7.5W — steady, safe top-up speed. It is not a 15W Qi2 unit; for speed, use the wire. 4. How fast is wired charging? 20W USB-C Power Delivery — an iPhone 16 Pro reaches 50% in roughly 30 minutes. 5. How many full charges will I get? Roughly 0.8–1.0 full charge for an iPhone 15/16/17 base model, slightly less for Pro Max sizes, after normal wireless conversion losses. 6. Can I use it through a case? Yes, through a MagSafe-compatible case. Non-magnetic or thick cases weaken the 10N hold and slow charging. 7. Can I take it on a plane? Yes — at 18.5Wh it is well under the FAA/TSA 100Wh carry-on limit. Pack it in carry-on, never checked luggage. 8. Can I charge the bank and my phone at the same time? Yes — pass-through charging works: plug the bank in, snap your phone on, and both fill up. 9. How long does the bank itself take to recharge? About 1.5–2 hours with an 18W+ USB-C PD adapter (estimated; adapter not included). 10. Will it damage my iPhone's battery? No — the NTC temperature chip and overcharge protection actively manage heat and current to protect long-term battery health. 11. How many times can I recharge the power bank? It is rated for 500+ full cycles without significant capacity loss — that is well over a year of daily recharging. 12. What colors are available? Gray, Blue, Pink, and Silver. 13. Do you offer free shipping? Yes — free shipping anywhere in the USA, and most orders arrive in under a week. 14. Is there a discount code? Yes — use code 10OFF at checkout for 10% off your entire order. 15. What is your return policy? To start a return, you can contact us at gorillacasestore@gmail.com. If your return is accepted, we'll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.

What Owners Are Saying

★★★★★ Marcus Webb, paramedic – Denver, USA: "Twelve-hour shifts kill phones. This thing lives on the back of my iPhone 15 between calls and I haven't seen low-battery red in months. You genuinely forget it's there."

★★★★★ Ingrid Sørensen, travel photographer – Oslo, Norway: "I shoot all day on an iPhone 16 Pro. The magnet is strong enough to trust while walking and the slim profile fits my jacket pocket with room to spare. Flew through three airports, zero issues."

★★★★★ Kenji Yamamoto, sales director – Osaka, Japan: "The 20W wired option saved a client dinner — 50% back in half an hour while we talked. Wireless for convenience, cable for emergencies. Smart design."

★★★★★ Amara Okafor, university lecturer – Lagos, Nigeria: "Power cuts make battery banks essential here. This one is the first that doesn't feel like carrying a brick. Snaps on my iPhone 14, charges reliably, stays cool."

★★★★½ Lucas Romero, rideshare driver – Buenos Aires, Argentina: "Charges my iPhone 13 about one full time, which is exactly as advertised. Wireless is not the fastest, but the magnet grip is excellent over bumpy roads. Wired charging is genuinely quick. Half a star off only because I wish it came with a wall adapter."
