UGreen MagFlow Magnetic Power Bank 10,000mAh Qi2 25W Review

Introduction

The UGreen MagFlow Magnetic Power Bank 10K Qi2 25W, aside from being an absolute mouthful, is one of the most capable wireless power banks around right now.

Taking advantage of the latest Qi2 standard and MagSafe capabilities, the MagFlow can stick to the back of recent models of iPhone (and some Androids) and deliver a faster 25W wireless charging experience, with an embedded USB-C cable delivering even faster 30W charge speeds.

I’ve spent the past week using the MagFlow to top up my various devices, and here’s what I’ve learnt. To see how it compares to the competition, take a look at our hand-picked selection of the best power banks. 

Design

• Pocketable design
• MagSafe support
• Integrated cable doubles as a handle

UGreen’s MagFlow Power Bank 10K represents the latest and greatest in wireless charging tech – and it looks good doing so.

Sporting a white and silver colour scheme that resembles Apple’s aesthetic, this power bank looks premium and, at a glance, you’d think it was made from aluminium – but picking it up, you’ll quickly realise it’s an all-plastic affair. That’s totally fine for a power bank, but worth noting nonetheless.

Most of the power bank is covered with a matte finish that helps negate fingerprints and other marks, with one silicone-covered side – the side that sports the main event, the Qi2 25W MagSafe charger. 

As you’d expect from a magnetic power bank, it snaps easily into place on the rear of supported devices. That has mainly been Apple’s iPhone range until recently, but we’ve started seeing Android phones, like the Google Pixel 10, offering built-in magnets – and they play well with MagSafe-branded accessories too.

Regardless of what you’re attaching it to, the collection of 17 N52 magnets creates a very secure connection – so secure that I could hold the Pixel 10 by the power bank and shake it without it coming free. I did this over a sofa, mind; I’m not quite confident enough to do it on a hard surface just yet.  

It’s clear that MagSafe charging is the main focus here, but the MagFlow also features an integrated 22cm USB-C cable for 30W charging that doubles as a handle. 

I’d be a little dubious about the wear and tear associated with its use as a handle, but the cables’ braided nature does give me more confidence that it’ll last. Ugreen also seems confident, claiming that the ‘military-grade’ cable will still work after 10,000 bends. 

Next to the integrated USB-C cable, you’ll find an additional USB-C port, used primarily for recharging the power bank, but it can also be used to charge an additional device. A small – some might say comically so – power button sits next to the port, with a single press all that’s needed to wake the device and the associated display.

The display is a helpful addition; embedded into the long side of the MagFlow, it displays the current percentage of power remaining in the power bank – a significant improvement over the strip of LEDs of old. That makes it easy to tell, at a glance, if you need to top it up before heading out on your journeys. There are also small icons for wireless charging and fast charging that appear when active. 

Unlike more premium options, both from UGreen and competitor Anker, that can display information like wattage when charging a device, this is mainly used to display battery levels. It’s still handy, but not quite as smart as it could be. 

Despite all this tech, it remains a relatively portable device, measuring in at 21mm thick and weighing in at 254g. Sure, it’ll add heft to your phone when attached, but it also doubles up as a handy grip. 

Performance

• Up to 25W wireless charging
• 30W charge speeds
• 2.5 hours to recharge the power bank

Let’s start with MagSafe charging performance, as that’ll be the reason why most people will pick up the MagFlow. 

It supports the latest Qi2 standard and delivers up to 25W wireless charging – but you need to make sure your phone also supports 25W. Recent models of iPhone – the iPhone 16 collection, as well as the newer iPhone 17 range – all support the faster wireless charging standard, but things are a little murkier on the Android side of things.

There are plenty of Android flagships with Qi2 support, including the likes of the Samsung Galaxy S25 Ultra and even the new Pixel 10 Pro, but they max out at a slightly slower 15W. Instead, they need to specifically support the Qi2.2 charging standard – something the Pixel 10 Pro XL offers, but not many others.

That said, snapping the MagFlow onto the rear of my Pixel 10, it regained 9% charge in 15 minutes and 17% in half an hour. Bear in mind that’s at 15W, so recent iPhone owners should expect something a little speedier – though I didn’t have a recent model to hand to test that theory. 

For faster, more efficient charging, the integrated USB-C cable is the go-to. With 30W charging and support for multiple charging standards, including PD 3.0, QC 4.0, and PPS, it’ll charge most iPhones quickly – although Android users accustomed to faster charging speeds may still find it a bit slow.

Regardless, it’ll charge faster than the wireless alternative; the Samsung Galaxy S25 Ultra, rated for up to 45W charging, regained a respectable 21% charge in just 15 minutes.  

You’ve also got the third USB-C port that you can plug a longer cable into, and it’ll deliver the same maximum 30W output as the integrated alternative – but only when you use one or the other, not both. While the MagFlow can charge three devices at once using its combination of and wireless options, charge speeds will be much slower. 

The 10,000mAh capacity equates to roughly two charges of the iPhone 17 Pro Max and Samsung Galaxy S25 Ultra, although the efficiency will depend on the charging method; wireless charging uses more electricity for a lower wattage than the alternative. 

When it comes to charging the MagFlow itself, support for 30W charging delivers a full charge of the power bank’s two 5000mAh cells in two and a half hours – slightly longer than UGreen’s two-hour recharge claim, but still a reasonable amount of time. 

You can also charge your devices while the power bank itself is charging – a handy feature not present on cheaper power banks.
