Benefits & Use Cases
This magnetic power bank is engineered for modern lifestyles where convenience meets reliability. The 5000mAh capacity provides approximately 0.67 full charges for an iPhone 17 Pro—ideal for a busy day of classes, work meetings, outdoor adventures, or long flights. Thanks to its slim build, it won’t snag in pockets or interfere with most phone cases, and the strong magnets allow for instant attachment without fumbling.
Perfect as a travel essential, dorm-room companion, or everyday commuter tool, the LISEN Qi2 battery pack supports active routines without added bulk. It works seamlessly with MagSafe-compatible cases, though users should avoid thick cases exceeding 2.5mm during wireless charging to prevent heat buildup. The included USB-C cable enables rapid recharging of the power bank itself, so you can stay topped up on the go. Its stylish, minimalist design also makes it a thoughtful gift for tech-savvy friends or family.
Important Notes
- Peak 15W wireless charging requires compatible devices such as iPhone 17/16/15/14/13/12 series and Pixel 10 Series. iPhone 16e supports 7.5W wireless charging.
- The rated capacity of 3000mAh accounts for a typical 35–45% loss due to battery cell inefficiencies and power conversion circuits—this reflects real-world usable output.
- Your iPhone may pause charging at 80% if it detects elevated temperature, as part of iOS 17’s built-in battery protection. Charging resumes automatically once the device cools down.
- Using your phone (especially gaming or video streaming) while charging can increase heat generation. For best results, remove the device from direct sunlight or hot environments.
- Thick phone cases over 2.5mm in thickness may block heat dissipation and trigger thermal throttling. Remove bulky cases during wireless charging sessions.
- The package includes: 1 LISEN Qi2 MagSafe Power Bank, 1 USB-C to USB-C cable (1.6ft), and access to responsive customer support backed by a 24-month warranty for peace of mind.
