f your current portable charger feels too simple, Ugreen has cooked up a flashy alternative that puts miniature plumbing right against your palm. The new MagFlow Pro Magnetic Power Bank packs a 10,000mAh battery for $149.99, catapulting standard pocket juice squarely into luxury showcase territory.
For that three-figure asking price, Ugreen claims the accessory delivers the first liquid-cooling loop inside a magnetic wireless power bank. A micro-pump circulates coolant across internal heat sinks and a Qi2.2-compatible wireless charging coil. You can even watch the fluid swirl through a transparent viewing window on the casing while your phone charges.
The heat problem and the power cap
Wireless magnetic charging notoriously wastes energy as heat, which bakes lithium-ion batteries and throttles charging speeds to a crawl. Ugreen counters this with its liquid loop, copper heat spreaders, and isolated circuitry designed to prevent thermal degradation and help sustain wireless output up to 25W without turning your phone into a hot brick.
The $149.99 MagFlow Pro is considerably more expensive than other 10,000mAh power banks.
For wired backups, the hardware includes an integrated USB-C cable lanyard and an additional USB-C port. Each can push up to 45W individually for tablets or ultrabooks, though total power output across the unit remains capped at 45W when charging multiple devices at once.
Paying triple the going rate for a 10,000mAh pack turns thermal control into an expensive novelty. Cramming a mechanical pump and liquid chambers into a pocket device adds moving parts that may not survive a drop onto concrete. Unless you refuse to let your handset get warm during wireless top-ups, a conventional wired power bank delivers identical charging speeds for a fraction of the price.
