MagSafe Power Bank for iPhone 12‑17

The golioklsy W12 is a 10000 mAh lithium‑ion power bank with MagSafe‑compatible magnetic attachment for iPhone 12 through 17 series. It delivers 15 W wireless charging and a 20 W USB‑C wired output for a second device. An integrated LED display shows remaining capacity at a glance.

Thermals Noise and Power Draw

The pack operates at 3.85 V and 3 A, staying cool and silent during typical phone top‑ups. Passive cooling means no fan noise, and the slim 0.66 in profile fits easily in a pocket or bag. Multi‑protection circuits guard against overheating, overcharging and short circuits.

Sustained Load Behaviour

Under continuous dual‑device charging the 10000 mAh cell supplies up to 30 hours of extra runtime for an iPhone 15 Pro Max. The 18 W USB‑C input recharges the bank itself between sessions. Not suited for users who need laptop‑level power delivery or multiple simultaneous high‑wattage ports.

Questions about this item

How do I attach the W12 power bank to my iPhone 15 Pro for wireless charging?

Align the built-in N52 magnets on the power bank with the MagSafe ring on the iPhone 15 Pro; it snaps into place automatically. The 0.66 in thickness adds minimal bulk while the magnetic hold stays secure during movement.

What part of the W12 will need replacement first with daily use?

The internal lithium-ion cell degrades over repeated charge cycles. The USB-C port and magnetic surface are solid-state with no moving parts, so the battery chemistry is the component that eventually requires a new power bank.

What stops the W12 from delivering its full 15 W wireless output during a long charging session?

The multi-protection system throttles power when internal temperature rises, so sustained 15 W wireless charging is limited by thermal regulation rather than the 10000 mAh capacity or the 20 W wired port.
