MagSafe 5000mAh Power Bank

The ViewSonic W5 is a slim lithium-polymer power bank built for MagSafe-compatible iPhones. It snaps onto the back of supported models from the iPhone 12 series through the iPhone 17 series using a 15N magnetic hold. The graphite-gray unit weighs 120 grams and measures 11.8 mm thick, leaving the camera clear for photos or video calls while charging.

15W Wireless Output

The single specification that decides fit is the 15-watt maximum wireless output delivered through the MagSafe alignment. This power level is fixed by the magnetic interface and the 5-volt, 3-amp rating. If your workflow demands faster wireless speeds or higher total capacity for multiple full phone charges, this 5000mAh unit will not meet that need.

USB-C Port and Pass-Through

A USB-C port provides up to 3 amps for wired charging of a second device or for recharging the power bank itself. The pack includes built-in cables and a user guide. Over-charge and short-circuit protection are integrated. The slim profile fits in a pocket, but the 5000mAh capacity typically provides roughly one full phone charge before the bank needs replenishing.
