Attending gaming conventions and fan events often means spending an entire day taking photos, recording videos, watching livestreams, checking schedules, and constantly staying connected on social media. As exciting as these events are, they’re also notorious for draining your smartphone’s battery long before the day ends.
Fortunately, the UGREEN MagFlow Air Magnetic Power Bank Honkai: Star Rail Edition proved to be the perfect companion during our visit to HoYo FEST 2026 at Spaces One Ayala in Makati, Philippines.
After spending an entire day covering the event and watching the highly anticipated Genshin Impact Special Program, this limited-edition power bank became one of the MVPs of our event kit.
A Premium Design Worthy of Any Trailblazer
UGREEN didn’t simply slap artwork onto a standard power bank.
The Honkai: Star Rail Edition immediately stands out with its premium finish and exclusive collaboration design that fans of the game will instantly appreciate. It feels more like a collectible accessory than just another charging device.
Its slim and lightweight profile also makes it incredibly easy to carry around. Whether tucked inside a small sling bag or slipped into a pocket, the MagFlow Air barely adds any noticeable weight, making it ideal for conventions, esports tournaments, concerts, or long days of travel.
For fans who enjoy showcasing their gaming merchandise, this power bank fits perfectly alongside any HoYoverse collection.
A Real-World Battery Test at HoYo FEST 2026
Specifications can only tell part of the story. The real test came during HoYo FEST 2026.
Our day started early and ended well into the evening. Throughout the event, we constantly used two smartphones to take photos, record videos, communicate with fellow media, browse event information, and watch the full Genshin Impact Special Program.
Despite the heavy workload, the UGREEN MagFlow Air Magnetic Power Bank Honkai: Star Rail Edition handled everything with ease.
It successfully charged both smartphones throughout the day, and impressively, it still had battery remaining by the time we headed home.
At no point did we need to hunt for a wall outlet or slow down our coverage just to conserve battery life. That peace of mind is invaluable, especially for media coverage or anyone attending all-day gaming events.
Cool Performance Even During Extended Charging
One concern many users have with magnetic wireless power banks is heat generation.
Thankfully, the MagFlow Air exceeded our expectations.
Even after spending hours charging two devices over the course of the day, it never became excessively hot. There was only minimal warmth during operation, making it comfortable to hold and reassuring to use for extended periods.
That cooler operating temperature also gave us more confidence while charging our phones continuously during a packed event schedule.
Built for More Than Just HoYoverse Fans
While its Honkai: Star Rail collaboration is undoubtedly its biggest selling point, the MagFlow Air offers plenty of practical value beyond its eye-catching design.
Its portability, dependable battery capacity, and magnetic wireless charging make it an excellent everyday accessory for gamers, students, travelers, professionals, and content creators alike.
Whether you’re attending conventions, covering esports tournaments, commuting around the city, or simply spending an entire day away from home, this is exactly the kind of accessory you’ll be glad you packed.
Final Verdict: A Stylish Power Bank That Delivers When It Matters Most
The UGREEN MagFlow Air Magnetic Power Bank Honkai: Star Rail Edition isn’t just a collector’s item—it’s a genuinely dependable everyday power bank that performs exactly when you need it most.
Our experience at HoYo FEST 2026 proved that it could comfortably support two heavily used smartphones throughout an entire day while remaining compact, portable, and surprisingly cool during extended charging sessions.
The exclusive Honkai: Star Rail aesthetic certainly makes it more appealing for HoYoverse fans, but even without the collaboration branding, the MagFlow Air stands on its own as an excellent portable charger.
If you’re a frequent convention-goer, content creator, gamer, or someone who simply refuses to let a dead battery interrupt your day, this is an accessory that’s easy to recommend.
