Ugreen’s liquid-cooled power bank tackles wireless charging heat

The 10,000mAh MagFlow Pro uses a micro-pump, fan and vapour chamber to limit thermal throttling, but its advanced cooling comes at a premium.

Accessory makers are steadily moving beyond capacity and port counts, and the latest example is Ugreen’s MagFlow Pro, a 10,000mAh magnetic power bank built around active liquid cooling. According to the company’s product claims and reports from IFA 2026, it is designed to keep charging speeds stable by managing heat rather than merely storing more energy. That makes it a notable entry in a market where thermal control is becoming a selling point in its own right.

The central feature is Ugreen’s CryoPulse cooling system, which uses a micro-pump, a fan, a copper vapour chamber and a separate internal layout to move coolant to the hottest parts of the charger. The aim is to reduce thermal throttling during wireless charging, when phones and chargers often become warm enough to cut power. The MagFlow Pro also includes a transparent window so users can see the coolant in motion, a detail that underlines how much the product is meant to be noticed as well as used. Reviewers say the system can keep the charger itself cooler, although it does not eliminate heat on the phone entirely.

In practical terms, the MagFlow Pro supports up to 25W wireless charging and 45W wired charging, with a built-in USB-C cable alongside a USB-C port. Ugreen says the liquid-cooling system consumes just 0.02W, suggesting the feature is intended to have little impact on overall efficiency. The company also claims the charger can take an iPhone 17 Pro Max to 50% in around 40 minutes over wireless charging, while US product pages describe a similar 30-minute 0% to 50% figure for the iPhone 17 Pro Max under Qi2.2 fast charging. That difference appears to reflect different charging conditions rather than a contradiction in the underlying hardware.

The trade-off is that the extra engineering comes at a premium. Vietnamese reporting puts the MagFlow Pro at 3.7 million dong, while other coverage from Europe and the United States places it at $149.99 or 119.99 euros depending on market and timing. That positions it above many conventional 10,000mAh wireless power banks, including some rival models that offer cooling fans but no liquid circuit or integrated cable. It is also slightly more limited on charging input than some competitors, meaning it can take longer to refill.

For buyers, the choice now depends less on battery size alone and more on the balance between convenience, heat management and cost. The MagFlow Pro is aimed at users who want sustained wireless performance, an integrated cable and a more elaborate thermal design in one unit. Others may prefer a simpler and cheaper battery pack, especially if they value compactness, silence or broad colour choice over a visible cooling system and higher-end materials.
