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

At just 0.3 inches thick, the TORRAS MiniMag PB4D adds a slim power boost without the bulk of a larger power bank. Its magnetic wireless charging makes it easy to attach to a compatible iPhone when you need power on the go. Want a backup that’s simple to carry on a commute or out for the day? The 5,000mAh capacity is designed for everyday top-ups.

Key specifications

• Capacity: 5,000mAh
• Dimensions: 4.01 x 2.5 x 0.3 inches

The slim profile is the main distinction from a bulkier power bank designed for extended charging away from an outlet. The MiniMag is intended as a portable daily backup: attach it magnetically for wireless charging, or use its USB-C connection for wired charging. Its compact format suits a commute, a day of errands, or keeping extra power close at work without carrying a full-size battery pack.

What it works with

The magnetic wireless charger is designed for compatible iPhone models, including iPhone 12 through iPhone 18 models listed for the product. The listed compatibility also includes Samsung Galaxy S23, S24, and S25 models and Google Pixel 7 and 8 models when used with a magnetic case. For wired charging, the product lists iPhone, Galaxy, Pixel, and iPad devices, along with Apple Watch, AirPods, and Pencil. Choose the charging method that suits your device: magnetic attachment for supported wireless charging, or a wired connection for devices and situations where that’s more practical.

Tips for day-to-day use

For a quick top-up while traveling or between appointments, attach the power bank to a compatible phone and keep using the phone as needed. Its 4.01-inch length and 0.3-inch thickness make it easy to slip into a pocket or bag when not attached. Use the wired output when you want to charge a listed device by cable, and the magnetic option for a cable-free phone setup.

Buyers often praise the slim shape, light feel, and appearance, with some noting that it sits neatly against a phone and fits conveniently in a pocket. Feedback on charging speed is mixed, and some buyers mention heat during use. The product lists a heat dissipation system among its features, keeping its charging method and everyday-backup role in mind helps set expectations for use.

What to clarify

Can it charge a phone wirelessly? Yes. It supports MagSafe wireless charging for compatible iPhone models. The listed Samsung Galaxy and Google Pixel models require a magnetic case for magnetic use.

Can I use it with devices other than an iPhone? Yes. The product lists wired charging for Galaxy, Pixel, and iPad devices, as well as Apple Watch, AirPods, and Pencil. Magnetic wireless use is listed for select Galaxy and Pixel phones with a magnetic case.

How much space does it take up? The power bank measures 4.01 x 2.5 x 0.3 inches, giving it a slim profile for carrying in a pocket or bag.

Is it worth it?

The MiniMag PB4D is a practical fit for someone who wants a pocketable 5,000mAh backup with magnetic wireless charging for a compatible iPhone and USB-C wired output for other listed devices. Its slim dimensions make it especially useful for commutes and daily outings where carrying a larger power bank would be less convenient.
