Ugreen Ultra Slim 5000mAh MagSafe Power Bank – Qi2 15W for iPhone

A phone that drops to 20 percent by mid-afternoon is a familiar kind of anxiety, and a magnetic power bank that clings to the back of your iPhone is one of the least annoying fixes for it. The UGREEN MagFlow Air — model PB561 — is aimed squarely at that problem, and its spec sheet suggests it takes the slim route rather than the giant-battery route.

What 12.5 Millimeters Actually Buys You

At roughly 104 x 68 x 12.5 mm and about 150 g, this is a pack meant to disappear into a pocket or a small bag without bulging. The shell combines aluminum alloy and plastic, so the surface that meets your phone should feel a step above plain polycarbonate. And the magnetic attachment is built in, which means no adhesive plate or bracket to fuss with.

• Battery capacity: 5,000 mAh (19.25 Wh), lithium-ion
• Dimensions: approx. 104 x 68 x 12.5 mm
• Weight: approx. 150 g
• Materials: aluminum alloy and plastic

Qi2 at 15W, Plus a 20W Wired Escape Hatch

Wireless charging runs on the Qi2 standard at up to 15W, with MagSafe compatibility confirmed and support for other Qi-enabled devices as well. That’s the headline feature. The USB-C port handles 20W output, and input is also 20W, so topping up the pack itself won’t eat your whole evening.

• Wireless output: 15W max (Qi2)
• Wired output: 20W max via USB-C
• USB-C input: 20W max (5V/3A, 9V/2.22A)
• USB-C output voltages: 5V/3A, 9V/2.22A, 12V/1.67A
• Compatibility: iPhone 12 and later, MagSafe/Qi2 devices, other Qi devices
• In the box: USB-C cable (may vary by retailer)

Small Cell, Honest Limits

Here’s the thing — 5,000 mAh is a top-up, not a weekend expedition. But does that really matter? For a commute, a long dinner, or an afternoon of heavy camera use, it’s typically enough to get you home. The 19.25 Wh energy rating also sits comfortably under common airline carry-on battery limits, which frequent flyers tend to care about.

Fair warning: the listing doesn’t break down how many full charges you’ll get on a specific iPhone model, so it’s worth confirming with the seller if that number is decisive for you.

Safety Hardware You Won’t See in Photos

Protection covers overcharge, over-discharge, overcurrent, overvoltage, short-circuit, overheat, and foreign object detection. Certifications include Qi2, CE, FCC, RoHS, and UN38.3 — the kind of paperwork that matters more than any marketing line.

If a pocketable Qi2 magnetic power bank is what you’re shopping for, this one deserves a spot on your shortlist.
