Revolutionizing Charging: UGREEN’s Liquid-Cooled Magnetic Power Bank

UGREEN has recently unveiled its latest MagFlow charging series at IFA 2026, featuring the debut of the first Qi2 25W magnetic power bank with active micro-pump liquid cooling. The lineup also includes a 3-in-1 magnetic charging stand and a foldable 2-in-1 charger, designed to manage heat production during high-power wireless charging.

Transitioning from the previous 15W standard to Qi2 25W results in a nearly 70% increase in charging power, accompanied by a corresponding escalation in heat emission. Excessive heat accumulation during wireless charging can lead to thermal throttling, slowing down the charging process and impacting battery longevity over time. UGREEN notes that with standard Qi2 system efficiency levels hovering around 70 to 75%, up to 30% of power could be lost as waste heat between the charger and the phone. At 25W output, this heat buildup accelerates rapidly, transforming peak charging into a brief burst rather than a sustained session.

To combat this, the MagFlow lineup integrates active cooling techniques with passive heat dissipation structures across all devices, featuring a system known as Thermal Guard to regulate temperature and power output throughout the range.

The flagship product within the range is the MagFlow Pro Magnetic Power Bank, a 10,000mAh unit that boasts the distinction of being the first power bank to employ micro-pump liquid cooling – a methodology commonly seen in high-performance gaming systems and PCs. The cooling mechanism, branded as CryoPulse, combines an active micro-pump with vapour chamber copper heat spreading foil and a segregated internal component layout to draw heat away from the cell. A transparent window on the back of the unit allows users to observe the coolant circulation.

UGREEN states that this cooling system maintains the peak surface temperature of an iPhone 17 Pro Max up to 10°C below a 48°C reference level used as an industry benchmark. The power bank supports Qi2 25W wireless charging alongside a maximum wired output of 45W through a built-in cable. UGREEN affirms that an iPhone 17 Pro Max, charging wirelessly from empty, reaches 50% battery capacity in approximately 40 minutes.

Internally, the power bank is equipped with ATL high-density battery cells featuring Dymondcell 2.0 protection, enhancing safety. The company asserts that the unit retains 90% of its capacity after 800 charge cycles. A small display on the unit indicates charging status, and the built-in USB-C cable serves as a wrist strap.

The MagFlow Pro 3-in-1 stand, designed for desk or bedside use, can simultaneously charge an iPhone, Apple Watch, and AirPods. Instead of liquid cooling, it incorporates what UGREEN terms a TEC Active Cooling System, coupling a thermoelectric cooling module with a fan emitting 15 decibels of noise or less. With cooling activated, UGREEN reports that the magnetic charging surface records around 11°C at its center during testing.

The stand delivers up to 25W to a compatible iPhone and provides full-speed charging to an Apple Watch through a Made for Apple Watch certified module. UGREEN states that the stand can charge an iPhone 17 Pro Max from empty to 50% in 26 minutes and an Apple Watch Series 11 to 50% in 19 minutes. A built-in display showcases power output, temperature, and the current cooling mode.

The most compact device in the lineup is the MagFlow 2-in-1 foldable charger, measuring 60 x 72 x 27mm when closed – compact enough to fit in a pocket or bag. When unfolded, it can deliver up to 25W to an iPhone and 5W to a pair of AirPods simultaneously, with the Thermal Guard system regulating heat output. UGREEN has added a broader anti-slip pad for positioning earbuds, along with a cool-touch glass charging surface.

The MagFlow series is set to be available for purchase across Europe starting from September 4, 2026. The UK pricing has been confirmed as £109.99 for the MagFlow Pro Magnetic Power Bank, £119.99 for the MagFlow Pro 3-in-1 Wireless Charging Stand, and £43.99 for the MagFlow 2-in-1 Foldable Wireless Charger.

UGREEN is showcasing its products in two halls at IFA 2026 for the first time, focusing on Communication and Connectivity in hall H3.2-153 and Smart Home in hall H2.2-135, under the banner ‘Smarter Living Starts Here’. The company has also been designated as an IFA 2026 Charging Partner and will offer complimentary charging at designated rest areas throughout the event.
