Liquid Cooling Makes UGREEN’s Qi2 Power Bank a Better Match for the Pixel 11 Pro

Yes, the Pixel 11 Pro supports Qi2.2 wireless charging up to 25W, and UGREEN’s MagFlow Pro Magnetic Power Bank 10000mAh 25W is designed to deliver that class of power. Its differentiator is a CryoPulse micro-pump liquid-cooling system intended to control the heat that normally builds up during fast magnetic charging. That makes it most compelling for people who regularly use fast wireless charging and dislike thermal throttling; it is a less obvious choice if the smallest, lightest or cheapest battery bank matters more.

Why this power bank is news for Pixel 11 Pro owners

UGREEN announced its MagFlow lineup on September 4, 2026. The MagFlow Pro combines a 10,000mAh battery with Qi2 wireless output up to 25W, a maximum wired output of 45W through a built-in USB-C cable, and a liquid-cooled thermal system. It is marketed as the “World’s First Liquid-Cooled Qi2 25W Power Bank.”

The timing matters because moving from the older 15W wireless level to Qi2 25W raises charging power by nearly 70%, according to UGREEN. More power also means more heat. Excess heat can cause a phone or charger to throttle, lengthen the charging session and, over repeated exposure, complicate battery-health management. The MagFlow Pro’s pitch is therefore not simply faster output; it is maintaining that output for longer.

Pixel 11 Pro compatibility: what is confirmed

Android Central reports that the Google Pixel 11, Pixel 11 Pro and Pixel 11 Pro XL support full Qi2 wireless charging and comply with Qi2.2, allowing wireless charging speeds of up to 25W. The Pixel 11 Pro therefore matches the MagFlow Pro’s headline wireless rating.

Matching ratings do not guarantee that every session will run at exactly 25W. Phone temperature, battery percentage, ambient temperature, alignment, cable use and the power bank’s control system can all change the instantaneous rate. There is no independent Pixel 11 Pro measurement confirming a sustained 25W session.

How the MagFlow Pro manages heat

UGREEN lists several parts working together rather than treating the cooling system as a single heat sink:

  • Transparent coolant window: lets you see the cooling fluid section.

On its product page, UGREEN reports “10℃ Cooler” and “44% Less Heat Buildup.” The footnote describes testing at 77°F, with a peak temperature up to 18°F lower than a 118°F industry benchmark, and warns that results vary by device, room temperature and usage. Those are manufacturer test claims, not an independent Pixel 11 Pro laboratory result.

UGREEN’s launch release also says an iPhone 17 Pro Max reached 50% in 40 minutes wirelessly. That is an iPhone test and should not be treated as Pixel 11 Pro performance. No published independent test establishes the MagFlow Pro’s sustained Pixel temperature, throttling point, long-term battery-health effect or acoustic output. The launch information does not specify whether the pump is audible in a quiet room, and it does not provide a pump or fan noise rating.

What 25W charging should feel like in practice

With the phone bare or in a properly aligned Qi2 case, the magnetic ring should center the charging coils without the manual positioning required by ordinary flat wireless pads. The 10,000mAh capacity gives the bank enough reserve for more than a quick emergency top-up, although usable energy is always lower than the printed cell capacity because of conversion and charging losses.

Wireless charging is convenient but less efficient than a cable. If you need the fastest possible recovery, the built-in USB-C cable and 45W wired output are the stronger option, assuming the Pixel 11 Pro accepts that input level under the same conditions. The wireless mode is the reason to buy this model: it keeps the phone usable while attached and avoids carrying a separate cable.

Who should buy it—and who should wait

The case for buying

  • You frequently use magnetic wireless charging and want the Pixel 11 Pro’s Qi2.2 capability rather than a 7.5W or 15W fallback.
  • Your current wireless battery bank becomes noticeably hot or slows down during longer sessions.
  • You want one accessory that offers magnetic wireless charging plus a 45W wired USB-C option.
  • You value active thermal management and are willing to accept that the independent Pixel measurements are not yet available.

Reasons to choose another power bank

  • You prioritize the thinnest or lightest daily-carry bank. The launch information does not provide dimensions or weight, so that comparison cannot yet be made.
  • You want the lowest price. UGREEN has not established a universal price or regional availability in the launch information.
  • You need silent operation. No measured pump or fan noise level is published.
  • You require proven Pixel-specific results. The available 50%-in-40-minutes example is from an iPhone 17 Pro Max, not a Pixel 11 Pro, and the temperature figures come from UGREEN’s own testing.

Availability and what to verify before ordering

The product was announced on September 4, 2026, but price, stock and exact regional listings are not established in the launch information. Before purchase, confirm that the listing is the 10,000mAh MagFlow Pro version, that it specifies Qi2 25W rather than a lower-output MagFlow model, and that the supplied USB-C cable and regional warranty match your market.

Also check the total thickness and weight in the local specification sheet, especially if you plan to leave it attached while holding the phone. If you use a case, verify that it is explicitly magnetic and Qi2-compatible; a conventional protective case can defeat the alignment that makes the system work.

Verdict for Pixel 11 Pro users

The MagFlow Pro is a credible answer to a real Qi2 problem: 25W wireless charging creates more heat than 15W, and UGREEN has built active cooling, copper spreading and adaptive controls around that constraint. Pixel 11 Pro compatibility is confirmed at the standards level, but the important practical questions—sustained Pixel charging speed, noise, dimensions, weight, price and long-term thermal behavior—still require device-specific testing or a complete regional listing. Buy it for the combination of Qi2 convenience and a serious cooling design, not on the assumption that every Pixel session will stay at 25W.
