Magnetic 5000 mAh Power Bank
The TORRAS PB4D is a MagSafe-compatible battery pack that snaps onto iPhone 12 through 17 models or MagSafe cases up to 0.3 inch thick. It provides wireless charging at 7.5 W and wired charging at 18 W over USB-C for users who want a cable-free top-up during a commute or workday. Android owners can add a magnetic ring case to use the same magnetic attachment.
Capacity and Daily Headroom
The 5000 mAh cell delivers roughly 65 to 70 percent charge to an iPhone 15 through 17, enough for a coffee-shop boost before a meeting or a flight-delay buffer. A wired USB-C session moves the phone from 30 to 80 percent in about 30 minutes. It is not suited for users who need multiple full phone recharges or want to power larger devices such as tablets over extended periods.
Thermals, Noise and Power Draw
An onboard NTC sensor monitors surface temperature in real time and automatically reduces output before overheating occurs, so the pack stays only slightly warm during fast wireless charging. The lithium-polymer cell is rated for 500-plus full charge cycles with minimal capacity loss and includes overcharge and over-discharge protection. Silent solid-state operation adds no audible noise in normal use.

Questions about this item
Will the 0.3 inch MagSafe snap hold through a MagSafe case on my iPhone 15 Pro?
The magnetic array is rated for bare iPhone 12-17 or MagSafe-compatible cases up to 0.3 inch thick, so a standard MagSafe case on an iPhone 15 Pro will stay firmly attached.
How do I know the NTC temperature monitor is keeping the PB4D safe during a 7.5W wireless charge?
A slight warmth means the NTC chip is actively regulating output; the system automatically reduces power before any overheat threshold is reached.
Does the box include a USB-C cable for the 18W wired input, or must I buy one separately?
The product information lists only the power bank itself; a USB-C cable for 18W input and 2A output is not included and must be purchased separately.
