ONEXFLY APEX Review: The Ultimate Handheld Gaming PC for Enthusiasts
The ONEXFLY APEX represents OneXPlayer’s most ambitious entry into the handheld gaming PC market, delivering desktop-level performance in a portable form factor. With AMD’s powerful Ryzen AI Max+ 395 processor and innovative tech features like removable batteries and optional liquid cooling, this device targets hardcore gamers willing to invest in premium portable performance.
Key Specifications at a Glance

Processor: AMD Ryzen AI Max+ 395 (16-core, 32-thread)
Graphics: Radeon 8060S integrated GPU
RAM: Up to 128GB LPDDR5X
Storage: Up to 8TB total (SSD + mini SSD + microSD)
Display: 8-inch, 1920×1200, 120Hz with VRR, ~500 nits brightness
TDP Range: 10W to 120W adjustable
Battery: 85Wh removable/swappable
Price: Starting at $1,399 (base model) to $2,200+ (top configuration)
Performance: Desktop Power Meets Portability

The APEX’s AMD Ryzen AI Max+ 395 processor delivers exceptional performance that rivals lower-end desktop GPUs. The adjustable power envelope of up to 120W TDP significantly outpaces competitors like the Steam Deck (~15W) and most Windows handhelds (30-45W), enabling sustained high clock speeds during demanding gaming sessions.
This raw power makes the APEX suitable not just for gaming, but also for productivity tasks like video editing and AI workloads, setting it apart from gaming-focused competitors.
Display and Controls
The 8-inch 120Hz display with Variable Refresh Rate support provides smooth, responsive visuals. At 1920×1200 resolution with approximately 500 nits brightness, the screen delivers sharp detail and vibrant colors suitable for both competitive gaming and cinematic experiences.
Control features include asymmetrical analog sticks, adjustable multi-stage triggers with customization options, and Hall effect joysticks designed to minimize drift over extended use. These premium controls aim to provide a more refined gaming experience than standard handheld designs.
Cooling Solutions: Choose Your Approach

The APEX offers two cooling configurations to match different usage scenarios:
Standard Dual-Fan Cooling: The built-in system handles everyday gaming at mid-range power levels effectively, maintaining reasonable thermals for portable use.
Optional Liquid Cooling Module: For users seeking maximum 120W performance, the silent liquid cooling attachment enables sustained peak output. However, this external hardware significantly reduces portability, potentially contradicting the handheld concept for some users.
Battery Life: Power vs Endurance
The detachable 85Wh battery allows mid-session swapping for continuous gameplay without charging downtime. Expected battery performance varies significantly with power settings:
- Low power (≈10W): 7+ hours
- Moderate power (≈25W): ~2 hours 20 minutes
- High performance (≈45W): ~1 hour 10 minutes
- Maximum power (120W): Under 1 hour
Community feedback suggests many users operate at 30-45W for balanced performance and battery life, carrying spare batteries for extended sessions.
Pricing and Configurations
The APEX positions itself firmly in the enthusiast market:
- Base model (Ryzen AI Max 385): Approximately $1,399+
- Top configuration (Ryzen AI Max+ 395, 128GB RAM): $2,200+
- Liquid cooling and additional batteries: Sold separately
This pricing places the APEX well above mainstream devices like the Steam Deck ($399+) and mid-range Windows handhelds ($800+).
