TORRAS MiniMag PB4D 5,000mAh Magnetic Power Bank, 0.3-Inch Slim

For iPhone users who want a compact battery boost during a commute or day out, the TORRAS MiniMag PB4D combines 5,000mAh capacity with magnetic wireless charging in a slim, pocket-friendly design. Attach it to a compatible phone for cable-free charging, or use the USB-C connection when a wired charge suits the moment.

Its 0.3-inch profile and 4-ounce weight make it easy to carry for everyday backup. Choose this streamlined format for a portable top-up, a larger power bank is a different fit for shoppers prioritizing more capacity in one pack.

Highlights

The MiniMag’s magnetic charging is designed for compatible iPhone models, including the listed iPhone 12 through iPhone 18 generations. Attach the power bank to the phone to start wireless charging without connecting a charging cable. For a wired option, it has a USB Type-C connector and supports fast charging. Built-in cables are also listed among the included components.

With 5,000mAh of capacity, this pack is intended as a handy reserve for daily travel, work, errands, or an evening out. Its compact shape keeps the charging setup close to the phone instead of requiring a separate, bulky pack in a bag. The Glacier White finish gives it a clean, simple look alongside a compatible iPhone.

Buyer feedback often appreciates the slim, lightweight feel and the way the pack fits with a phone. Experiences with charging speed and durability are mixed, and some buyers report that it gets hot during use. These are individual impressions rather than a measure of performance for every use.

Quick sizing guide

The power bank measures 4.01 inches long by 2.5 inches wide and 0.3 inches thick, and weighs 4 ounces. Those dimensions help when deciding whether it suits a pocket, small bag, or a phone-and-charger setup you want to keep compact. If you plan to use magnetic charging, choose a compatible iPhone model from the listed range, the USB Type-C connection provides a wired charging option.

Tips for day-to-day use

For a commute, attach the MiniMag to a compatible iPhone when you want to keep the phone and backup power together, without a loose cable between them. At a desk or while packing for an outing, use the USB Type-C connection for wired charging. The product also lists a heat dissipation system among its features. Its slim format is especially practical when a separate, higher-capacity battery pack would be more than you want to carry for routine use.

Should you buy it?

Worth considering if you want a light, 5,000mAh backup that can attach magnetically to a compatible iPhone and also offers USB-C wired charging. The MiniMag PB4D brings those options together in a 0.3-inch-thin design, making it a practical everyday companion for commutes, errands, and other outings where compact carry matters.
