Ultra-slim 5000mAh magnetic power bank

The TORRAS PB4D is a 5000mAh lithium-cobalt power bank built for iPhone 12 through 17 series users who want a daily battery boost without bulk. At 0.3 inches thick and 4 ounces, it attaches magnetically and nearly disappears against the handset. It suits commuters and travellers who value pocketable capacity over multiple full charges.

Magnetic attachment with USB-C cable included

The box supplies a USB-C cable so the bank can be recharged at 9V or used for 22.5W wired output. Magnetic wireless charging delivers up to 15W on compatible iPhones, removing the need to carry a separate cable for top-ups. The snap-on hold means the bank stays aligned while the phone is in use or moving inside a bag.

Single-day top-up capacity with 15W wireless ceiling

A 5000mAh cell typically adds one partial charge for modern iPhones, enough for an extended workday or evening out. Wireless output caps at 15W, so it will not match the speed of wired fast charging on the same devices. Users needing several full cycles or higher wireless wattage should look at larger banks.

Questions about this item

Does the lithium-cobalt cell in the PB4D degrade faster than other chemistries?

The cell uses lithium-cobalt chemistry rated at 5000 mAh; like all lithium-ion cells it loses capacity over hundreds of charge cycles, but no cycle-life figure is published.

What limits output first during a long charging session — the 22.5 W wired or 15 W wireless ceiling?

Wireless charging caps at 15 W for iPhone 12-17 models, while wired USB-C reaches 22.5 W; the lower wireless ceiling will be hit first when charging magnetically.

How warm does the 0.3 in thick pack get when it runs at 15 W wireless all day?

At 4 oz and 0.3 in thick the aluminium shell dissipates heat, but sustained 15 W wireless output will warm the surface noticeably; no thermal-throttle temperature is specified.
