Magnetic power bank for iPhone
The golioklsy W12 is a 10000mAh lithium-ion power bank that attaches magnetically to MagSafe-compatible iPhone 12 through 17 series devices. It delivers up to 20W wireless charging and 20W wired charging via its USB-C port. An integrated LED display shows the remaining capacity.
Thermals noise and power draw
The unit operates at 3.85V and 3A, supplying up to 20W through either the wireless coil or the USB-C output. Passive cooling keeps it silent during charging. The compact 4.12 x 2.7 x 0.66 in form factor fits in a pocket without blocking the iPhone rear camera.
20W wireless output decides fit
This power bank provides 20W magnetic wireless charging, faster than the common 15W limit on many MagSafe accessories. Buyers whose iPhone or case lacks MagSafe magnets cannot use the wireless function. Users needing more than roughly 2.2 full charges for an iPhone 15 Pro should consider a higher-capacity unit.

Questions about this item
How do I attach the W12 to my iPhone so the 20 W wireless charging starts, and what step do people skip?
Align the power bank's magnetic ring with the iPhone 12/13/14/15/16/17 series MagSafe array; the missing step is pressing firmly until the magnets snap audibly, otherwise the 20 W rate will not engage.
What part of the W12 will need replacement first and when?
The internal 10000 mAh lithium-ion cell at 3.85 V is the only consumable; expect to replace the whole unit once runtime falls below your needs, typically after several hundred full cycles.
What limit appears first when I use the 20 W wireless output continuously?
Sustained 20 W wireless charging generates heat that triggers thermal throttling, reducing output before the 10000 mAh capacity is fully depleted.
