UGREEN has unveiled MagFlow, a new family of charging accessories. The headline product is a 10,000mAh magnetic power bank with an active liquid-cooling loop driven by a micro pump. It answers the heat problem that came with the jump to Qi2 25W wireless charging by borrowing a technique familiar from PC building, and a transparent window lets you watch the coolant circulate.

PC Cooling, Shrunk Into a Power Bank

At the heart of the MagFlow Pro is a micro-pump liquid-cooling system UGREEN calls CryoPulse. A small pump circulates coolant to carry heat away directly from the source, and UGREEN says this is the first time the approach has been used inside a power bank. Liquid cooling is ordinary in high-performance PCs and servers, but nobody had squeezed it into something that fits in a palm.

Cooling does not rest on the pump alone. A copper vapor chamber (VC) heat-spreading foil distributes heat across a surface, and separating the charging components from the cells keeps heat from pooling in one place. A control layer called ThermalGuard adjusts output automatically according to temperature.

The body also carries a transparent window that shows the coolant moving through the loop. Cooling hardware is normally buried inside a chassis where you never notice it exists. Choosing to expose it turns proof that the system is working into part of the reason to buy the thing.

The Move to 25W Brought the Heat With It

The reason UGREEN leaned this hard on cooling is that wireless charging power has climbed a step. Going from the previous 15W to Qi2 25W raises charging power by roughly 70 percent. More power means more heat, and once heat builds up, protection circuits throttle output and charging slows down. Battery health suffers too. If you want speed, you have to cool it. That physical constraint is where this product starts.

In UGREEN's own testing, peak temperature on an iPhone 17 Pro Max landed up to 10°C below the 48°C figure the company cites as an industry reference. On speed, UGREEN reports an iPhone 17 Pro Max reaching 50 percent in 40 minutes over the wireless connection.

On the wired side, a built-in cable handles up to 45W. That cable doubles as a carry strap, so there is no separate cable to remember. Capacity is 10,000mAh, and a display shows remaining charge and charging status.

The cells are ATL high-density units paired with a multi-layer protection scheme UGREEN calls Dymondcell 2.0. The company cites crush and needle-puncture tests, a 140°C heat test, and a life test retaining more than 80 percent capacity after 800 cycles. Having added a liquid loop, UGREEN clearly felt it needed to spend words on the safety side as well.

A 3-in-1 Stand With a Cooling Fan

MagFlow is a three-model series rather than a single power bank.

The MagFlow Pro 3-in-1 Magnetic Wireless Charging Stand is a desk unit that charges an iPhone, an Apple Watch and AirPods at once. Instead of liquid cooling it uses active cooling built from a TEC module (a Peltier element) and an ultra-quiet fan rated at 15dB or below. It delivers up to 25W to an iPhone and full-speed Apple Watch charging through an MFW-certified module, and UGREEN's testing puts an iPhone 17 Pro Max at 50 percent in 26 minutes and an Apple Watch Series 11 at 50 percent in 19 minutes. The display shows output, temperature and cooling mode.

The third model, the MagFlow 2-in-1 Foldable Magnetic Wireless Charger, measures 60 x 72 x 27mm folded and is aimed at travel. Opened up, it supplies up to 25W to an iPhone and 5W to AirPods simultaneously. Cooling here is handled by ThermalGuard, with a wider anti-slip pad for earbuds to make placement easier and a cool-touch glass surface.

Pricing and Availability

The series went on sale across Europe on September 4, 2026. Suggested retail is 119.99 EUR (about 22,000 yen) or 109.99 GBP (about 23,000 yen) for the power bank, 139.99 EUR (about 25,000 yen) or 119.99 GBP (about 25,000 yen) for the 3-in-1 stand, and 49.99 EUR (about 9,000 yen) or 43.99 GBP (about 9,000 yen) for the 2-in-1 charger. In the United States, UGREEN's official store lists the MagFlow Pro power bank at 149.99 USD (about 23,000 yen). No Japanese release date or pricing has been announced as of this writing.

※Exchange rates as of September 8, 2026: 1 EUR = 181 JPY, 1 GBP = 211 JPY, 1 USD = 156 JPY

UGREEN also exhibited across two halls at IFA 2026 for the first time, splitting communication and connectivity into H3.2-153 and smart home into H2.2-135. As a charging partner for the show, it provided free charging at designated rest areas.

Summary

The MagFlow Pro handles the extra heat of Qi2 25W with a micro-pump liquid loop, a design with no precedent in a power bank. Including the window that shows coolant moving, it turns the engineering behind the performance claim into the product's visible selling point. Everyone knew heat was why wireless charging stayed slow, and nobody had done much about it; UGREEN brought over the answer from the PC side. Japanese availability is unclear, but it is a legible example of where 25W-generation wireless charging runs into its limits.
