High-capacity battery with wireless charging

The Ugreen MagFlow Pro is a high-end external battery with wireless charging capabilities and two USB-C ports. It features an integrated USB-C cable that can also be used as a strap, making it both functional and portable.

Technical specifications and design

With a capacity of 10,000 mAh, the MagFlow Pro measures 10.8 x 7.1 x 1.6 cm and weighs 221 grams. It can deliver up to 25 W through its Qi 2.2 certified magnetic wireless charger, and the two USB-C ports can provide up to 45 W of power. It is also the first external battery of its kind to include an integrated liquid cooling system.

Safety and durability features

The device includes multiple layers of protection, such as resistance to crushing, needle puncture, and heat tests at 140 °C without catching fire or exploding. It is rated for at least 800 charge/discharge cycles and is marked as "Airline-Approved," indicating it meets safety standards for air travel.

Cooling system design and performance

The liquid cooling system is located between a copper sheet and an aluminum heat sink casing. It uses a micro-pump that consumes 0.02 W of energy and circulates liquid through tubes. The system redistributes heat but does not reduce the total amount of heat the device must dissipate.

User experience and pricing

The MagFlow Pro is priced at 100 euros, similar to other high-end 10,000 mAh batteries like the Anker MagGo 2 Pro. It is described as a "small technological jewel" that may spark conversations, though the micro-pump could be a potential point of failure in the long term.

Testing and thermal performance

Thermal camera tests showed that the side with the liquid cooler was slightly cooler, while the charging base was slightly warmer. This indicates that the cooling system effectively redistributes heat. Some users have noted that the device may limit charging speed, but this only occurs if the device is at risk of overheating.
