25W wireless charging generates real heat, and without proper cooling, an iPhone can slow down or even stop charging. Ugreen’s approach to managing that heat is noticeably more aggressive than most with fan and liquid cooling.

What is the exact battery capacity of the Ugreen MagFlow Pro?
10,000 mAh (10K) is still the largest size that can comfortably hold a MagSafe iPhone without feeling too bulky to put in your pocket. If you want something more compact, a 5000mAh (5K) power bank is worth considering, but you’ll get fewer recharges with the smaller portable charger. Read reviews of the best magnetic power banks we’ve tested, both 5K and 10K.
It is worth noting that not all â10Kâ power banks have the same actual capacity; Watt hours (Wh) are a more precise measurement. The Ugreen MagFlow Pro’s 39.2 Wh is on the high end of what we’ve tested and above the average 10K capacity of 38.2 Wh.
How fast is the Ugreen MagFlow Pro?
For wireless output, the MagFlow Pro has the maximum speed of 25W of Qi2.2. Only the iPhone 16 and later can consume the full 25W; Older models, along with the 17e, cap at 15W and the iPhone Air at 20W. The difference between 25W and 15W wireless charging is about 15 minutes for the iPhone to reach 50% – 30 minutes vs. 45 minutes.
The MagFlow Pro’s standout feature isn’t just its 25W wireless speed. Its 45W USB-C port is only comparable to the Anker MagGo Power Bank 2 Pro and the Baseus PicoGo AM52 among the chargers we’ve tested. However, unlike the Anker, the Ugreen includes a built-in USB-C cable (also 45W capable), so you don’t need to carry one separately, which is a real convenience.
That built-in cable also gives you three simultaneous charging options: wireless, the built-in USB-C cable, and the USB-C port. However, as with most multi-device chargers, the total power decreases when more than one device is connected; in this case, at just 15W. This can still be useful for recharging an Apple Watch or AirPods along with your iPhone. You can also charge an AirPods case on the wireless charging pad when your iPhone is not connected.
