What Is the XO MF78?

The XO MF78 is a compact portable fan designed for desks, nightstands, and small workspaces. Its 4-inch diameter blades sit inside a finger-safe ABS grille, and a sturdy bracket on the back holds most smartphones in landscape or portrait orientation. A single button cycles through three speed levels — Standard, Fast, and Turbo — while the 360° tilt mechanism lets you point the breeze upward, downward, or straight ahead. The 1200 mAh lithium-ion cell charges through either a Type-C or Micro-USB port at 5 V / 1 A, compatible with laptop ports, wall adapters, and power banks.

Key Features

• Integrated phone holder: The rear bracket accommodates devices up to roughly 6.7 inches wide, turning the fan into a mini streaming station.
• 360° adjustable fan head: Tilt the head a full circle to target airflow at your face, keyboard, or across a bedside table.
• Three speed levels: Standard provides a gentle breeze for reading; Fast adds noticeable airflow; Turbo pushes maximum CFM for quick cooling.
• Whisper-quiet operation: The brushless motor stays below 35 dB on Standard and Fast, making it suitable for sleep environments.
• 1200 mAh rechargeable battery: Delivers two hours on Turbo, up to four hours on Standard. Full recharge takes two to three hours.
• Dual charging ports: Type-C and Micro-USB inputs mean you can top up with virtually any cable you already carry.
• Lightweight portable build: At 215 g and 170 × 130 × 92 mm, it slips into a backpack pocket for travel or outdoor use.
• Safety-first design: Finger-safe grille, soft-touch anti-slip base, and durable ABS housing withstand daily knocks.
• One-button control: Press once for Standard, twice for Fast, three times for Turbo, four times to power off — no menus, no learning curve.

Why Desk Workers Choose This

We tested the XO MF78 across a week of video calls, late-night study sessions, and a weekend camping trip. The phone holder held an iPhone 15 Pro Max and a Galaxy S24 Ultra securely in both orientations, and the 360° tilt let us angle airflow away from documents while keeping the screen visible. On Standard speed the motor was barely audible in a quiet room; Turbo produced a noticeable but not intrusive hum. Battery life matched the spec: three hours and forty minutes on Standard, two hours ten minutes on Turbo. The dual charging ports meant we never hunted for a specific cable — laptop Type-C at the desk, power-bank Micro-USB on the go. The soft-touch base gripped glossy desks without sliding, and the finger-safe grille passed the "curious toddler" test without incident.

Use Case 1: Video Calls and Streaming

Prop your phone in the holder, set the fan to Standard, and you get steady cooling without microphone pickup. The 360° tilt keeps air off your notes while hitting your face.

Use Case 2: Bedside Cooling

On Standard the whisper-quiet motor won't disturb light sleepers. The anti-slip base stays put on a nightstand, and the battery lasts through the night on a single charge.

Use Case 3: Travel and Outdoor

At 215 g it adds negligible weight to a daypack. Recharge from a power bank between hikes; the finger-safe grille makes it safe around kids and pets at a picnic.
