Introduction
In 2025, handheld gaming PCs are no longer niche gadgets — they are serious contenders for gamers who demand desktop-level performance in a portable body. Enter the OneXFly Apex, a device that aims to shatter expectations with its high-end specifications and groundbreaking cooling and power architecture. In this review we’ll explore its hardware, use-case, strengths, trade-offs, and if it truly deserves a spot among the “best handhelds of 2025”.
What the OneXFly Apex Brings to the Table
The Apex is engineered with some truly top-tier specs that separate it from many competitors:
- It is powered by the AMD Ryzen AI Max+ 395 APU, a next-gen mobile processor featuring 16 Zen 5 cores and Radeon graphics. Tom’s Hardware+2Wccftech+2
- The system supports up to 128 GB of RAM (with reports of up to 96 GB dedicated as VRAM in some configurations). Wccftech+1
- A major headline: a 120 W TDP ceiling, enabled by an optional external liquid-cooling module and advanced internal cooling design. Tom’s Hardware+1
- The display is an 8-inch, 120 Hz (or higher) panel with VRR, optimized for high-frame-rate portable gaming. Android Authority+1
- To fuel all this, it uses an 85Wh external battery pack (clip-on style) to sustain the high-power hardware, though actual runtime will depend on load. Notebookcheck+1
- Storage and expandability: M.2 internal slot plus external mini-SSD slot, high-spec memory and storage bandwidth. Liliputing+1
In short: the Apex isn’t just another handheld — it’s a “desktop-in-hand” concept, pushing performance boundaries.
Performance & Real-World Use
Raw power and benchmark insights
Early reports from tech outlets show impressive numbers: for example, at lower TDPs the Apex already out-paces many handhelds; at full 120W (when using external cooling) it theoretically reaches desktop-class scores. Wccftech+1
However — and this is key — using full power means higher thermal output, likely needing the external cooling module, and means battery life takes a hit.
Gaming experience
With its high refresh display and powerful GPU, the Apex is built for high-end AAA PC games on the go. Games running at 1080p or 1440p with high settings should be viable. That said, users should expect trade-offs: battery life will be shorter at high wattage, the device size and weight may be higher than lighter handhelds, and heat/ergonomics will matter more due to the performance envelope.
The portability vs power trade-off
This is where the Apex stands out — and also where buyers must be clear about expectations. The external battery, optional water cooling, high-wattage TDP all add bulk or dependency on accessories. So while technically “handheld”, its optimum use may be closer to “mobile desktop” than ultra-light handheld for travel.
Build, Design & Features
- The controls include high-quality analog sticks, multi-stage triggers, and premium audio (Harman-tuned speakers) in some reports. Tom’s Hardware+1
- Connectivity: USB4, high-speed ports, future-proof storage and expansion. Wccftech
- The external battery pack concept means you can swap or upgrade battery modules, potentially extending gaming sessions beyond what internal cells alone allow.
Strengths & What It Excels At
- Performance ceiling: very few handhelds can match the Apex when fully enabled.
- Expandable and modular design: high RAM/storage ceiling; upgrade path built in.
- Display quality: 8-inch high refresh VRR panel gives immersive visuals.
- Future-proofing: Designed for hardcore gamers who want cutting-edge hardware.
Trade-Offs & What to Consider
- Price: Early Chinese indications show starting around ~$1,200 for base model; higher end models with full specs will cost much more. Liliputing+1
- Size/weight: At full power, the device will be larger/heavier than ultra-portable handhelds; external battery and cooling accessories increase bulk. Android Authority+1
- Battery life at full performance: While battery capacity is large, running at 80-120W will drain quickly; in handheld mode use you may need to reduce wattage.
- Use scenarios: The apex mode (120W + liquid cooling) is likely best for stationary or plugged-in use, not pure on-the-go handheld use.
- Software/driver maturity: With high-end hardware comes need for optimized drivers and heat/power tuning, which sometimes lag at launch.
Who Should Buy the OneXFly Apex?
- Gamers who demand near-desktop visuals and performance in a portable form and are comfortable investing premium.
- Users who already carry accessories, power banks, and anticipate using handheld for serious gaming rather than quick casual sessions.
- Tech enthusiasts who value upgradeability, future-proof hardware, and are okay with some trade-off in portability for raw power.
If you’re looking for a lightweight, ultra-affordable handheld for casual gaming, the Apex might be overkill (and expensive) for your needs.
Final Verdict
The OneXFly Apex is a bold statement device in the 2025 handheld gaming PC space. It pushes the envelope on hardware, cooling, performance and upgradeability. For those who want the ultimate portable PC gaming device — and are willing to accept some compromises in battery life, portability and cost — it may well be the most compelling option available right now.
That said, it isn’t perfect. The real world usability (battery, cooling, size) will dictate how much of its power you can reliably access. If you’re prepared for that and excited by high-end specs, then the Apex is worth serious consideration.
In short: If you want “desktop-class gaming, handheld form factor, 2025 technology”, then the OneXFly Apex checks those boxes better than most. If you want pure portability, minimal accessories and lower cost, there are other handhelds that may serve better.
