Magnetic Power Bank 5000mAh 15W

The NU F20 is a magnetic portable charger built for iPhone 12 through 17 series models. It stores 5000mAh of energy in a lithium-polymer cell and delivers up to 15W of wireless power through MagSafe-compatible alignment. A USB-C port adds 20W Power Delivery output for wired charging. The unit measures 4.1 by 2.55 by 0.27 inches and weighs 70 grams.

Suits iPhone 12 to 17 users wanting cable-free

This charger fits owners of iPhone 12, 13, 14, 15, 16 and 17 series handsets including Pro, Pro Max, Plus and mini variants. The magnetic array aligns automatically and does not block the camera on smaller models such as the 13 mini. Buyers who need more than one full phone charge or who use Android devices without magnetic cases should look at other options.

5000mAh capacity decides daily usefulness

The 5000mAh cell provides roughly one complete recharge for most supported iPhones. If your routine demands multiple top-ups between wall outlets, this capacity will fall short. For single-day carry or emergency backup the stored energy is adequate.

Questions about this item

Does the F20 need a USB-C charger to reach its 20W wired output?

Yes, a USB-C PD charger of at least 20W is required for the power bank to deliver its maximum wired output.

Will the magnetic attachment work on an iPhone 12 without a MagSafe case?

The built-in magnets align with the iPhone 12's internal MagSafe array, so it attaches securely even on a bare phone.

How do I confirm the F20 is delivering 15W wireless fast charging?

The digital display shows real-time output; when it reads 15W during wireless use, the charger is operating at its top wireless speed.
