From rugged waterproof cases to high-performance mounts and external mics, these add-ons deliver pro-level results in any environment—ensuring crisp 4K footage whether you’re diving, hiking, or capturing high-speed action.

Key Takeaways

• Upgrade your grip: Use a sturdy tripod mount for shake-free 4K footage.
• Enhance low-light shots: Add an external LED light for brighter, clearer videos.
• Protect your lens: Always use a UV filter to avoid scratches and glare.

• Improve audio quality: Attach an external mic for crisp, professional sound.
• Expand storage capacity: Use high-speed microSD cards to avoid recording interruptions.

Why the Right Accessories Can Make or Break Your Mi Action Camera 4K Experience

Let’s be honest: the Mi Action Camera 4K is a solid little beast. It shoots crisp 4K video, handles bumps like a champ, and won’t burn a hole in your wallet. But here’s the thing — no matter how good the camera is, it’s only as good as the gear you pair it with. I learned this the hard way when I took mine on a mountain biking trip. I had the camera, a cheap selfie stick, and zero planning. The result? Blurry footage, shaky angles, and a cracked lens cap after a minor fall. Not exactly the epic adventure reel I was hoping for.

That’s when I realized: accessories aren’t just extras — they’re essential. The right ones don’t just protect your gear; they unlock the full potential of your Mi Action Camera 4K. Whether you’re filming a sunrise hike, a surfing session, or your kid’s first soccer goal, the right mounts, batteries, and lenses can turn shaky clips into cinematic moments. In this guide, I’ll walk you through the top Mi Action Camera 4K accessories that actually make a difference. No fluff, no sponsored hype — just honest, tested picks to help you capture stunning shots, every time.

1. Mounts That Keep Your Camera Steady — Wherever You Go

Mounts are the unsung heroes of action photography. A great mount keeps your Mi Action Camera 4K stable, secure, and perfectly angled. But not all mounts are created equal. Here’s what works — and what doesn’t.

Helmet Mounts: For First-Person POV

Helmet mounts are ideal for biking, skiing, or skateboarding. They give that immersive, “you are there” feel. The Mi Action Camera 4K helmet mount kit (sold separately or in bundles) includes a curved adhesive base and a quick-release arm. I’ve used it on both a full-face MTB helmet and a ski helmet. The adhesive holds well in cold and wet conditions — but make sure you clean the surface with alcohol wipes first. One tip: apply it in a warm room. Cold surfaces can weaken the bond.

• Best for: Cycling, skiing, snowboarding, skateboarding
• Pro tip: Use a safety tether (sold separately) — I once lost a camera on a downhill trail because the mount loosened mid-ride.
• Watch out: Avoid mounting on textured or curved surfaces. Flat areas work best.

Handlebar & Roll Bar Mounts: Perfect for Bikes and Vehicles

If you’re into mountain biking or off-roading, a handlebar mount is a must. The Mi 360° rotating handlebar mount lets you adjust the angle on the fly. I use it on my gravel bike — the rubberized clamp grips tight, even on bumpy trails. It’s also great for mounting on ATVs, motorcycles, or even a stroller (yes, I’ve done that for family vlogs).

• Best for: Bicycles, motorcycles, ATVs, strollers
• Pro tip: Tighten the clamp with a coin — it’s easier than using a screwdriver on the trail.
• Watch out: Check the clamp size. The standard fits 22–35mm bars. If you have a fat MTB bar, you might need an adapter.

Chest Mounts: For Dynamic, Stable Footage

Chest mounts are my go-to for hiking and trail running. They’re more stable than head mounts because they’re lower to the ground and follow your body’s natural movement. The Mi chest strap mount is lightweight and adjustable. I’ve worn it for 4-hour hikes — no chafing, no slipping.

• Best for: Hiking, trail running, climbing
• Pro tip: Position the camera just below your collarbone for the best field of view.
• Watch out: If you’re wearing a backpack, make sure the straps don’t interfere with the mount.

2. Power Solutions: Never Run Out of Juice Mid-Shoot

There’s nothing worse than your Mi Action Camera 4K dying halfway through a shoot. The stock battery lasts about 90 minutes in 4K mode — which sounds fine, until you’re in the middle of a waterfall or a 10-mile bike ride. That’s why extra batteries and smart charging solutions are non-negotiable.

Extra Batteries: The Lifeline of Action Filming

Always carry at least one spare battery. The Mi Action Camera 4K battery (1200mAh) is the same as the stock one, but third-party options like Wasabi Power or Duracell offer 1300mAh for slightly longer life. I keep two spares in a padded case — one in my pocket, one in my bag.

• Best for: Long shoots, travel, remote locations
• Pro tip: Label your batteries — “used” vs. “fresh” — so you don’t accidentally swap in a dead one.
• Watch out: Third-party batteries may not charge as fast in the official dock. Use them, but test them first.

Dual-Slot Battery Charger: Charge Two at Once

The Mi dual-slot USB charger lets you charge two batteries simultaneously from a power bank, laptop, or car USB. It’s compact and includes overcharge protection. I keep it in my camera bag — it’s a game-changer when you’re traveling.

• Best for: Travel, on-the-go charging
• Pro tip: Pair it with a 20,000mAh power bank. I can charge both batteries and my phone twice on a single charge.
• Watch out: Some third-party chargers don’t fit the Mi battery shape. Stick with Mi or trusted brands like Nitecore.

Car Charger Adapter: Power Up on the Move

If you’re driving to a shoot, a 12V car charger lets you charge batteries in the car. The Mi USB car adapter plugs into your cigarette lighter and has two USB ports. I use it on road trips — by the time I arrive, my batteries are full.

• Best for: Road trips, long drives
• Pro tip: Use a coiled cable to avoid tangles.
• Watch out: Don’t leave the adapter plugged in when the car is off — it can drain the battery.

3. Lens & Housing Upgrades: Protect and Enhance Your Shots

The Mi Action Camera 4K already has a rugged housing, but the right lens and housing upgrades can take your footage from “good” to “great.”

Replacement Lens Cover: Prevent Scratches

The stock lens cover is plastic — and it scratches easily. I learned this after a single rock climb. The Mi tempered glass lens cover is a cheap upgrade that makes a big difference. It’s 9H hardness and fits snugly. I’ve dropped my camera twice — no scratches.

• Best for: Climbing, kayaking, any activity with debris
• Pro tip: Clean the lens with a microfiber cloth before applying the cover to avoid trapped dust.
• Watch out: Some third-party covers don’t align with the camera’s mic. Stick with Mi or brands that specify Mi 4K compatibility.

Underwater Housing: Dive Deeper

The stock housing is waterproof to 40m, but the Mi underwater housing (sold separately) is rated to 60m and has a better seal. It’s essential for scuba diving or deep snorkeling. I used it in a coral reef — the colors popped, and the housing stayed dry.

• Best for: Scuba diving, snorkeling, deep-water activities
• Pro tip: Test the housing in a pool first — better safe than sorry.
• Watch out: The housing adds bulk. If you’re using a chest mount, it might feel top-heavy.

Wide-Angle Lens Adapter: Expand Your Field of View

The Mi 4K has a 145° FOV, but the Mi wide-angle lens adapter (sold separately) bumps it to 170° — great for tight spaces or immersive shots. I used it in a cave — it captured the entire ceiling and walls.

• Best for: Caves, tight spaces, immersive POV
• Pro tip: Remove the adapter when not in use — it’s easy to lose.
• Watch out: It can cause slight barrel distortion. Use it for dramatic effect, not for straight lines.

4. Audio & Connectivity: Capture Crisp Sound and Stream Seamlessly

Great video is only half the story. Bad audio can ruin an otherwise perfect clip. And if you’re live-streaming, you need reliable connectivity.

External Microphone Adapter

The Mi 4K has a built-in mic, but it’s easily muffled by wind or housing. The Mi external mic adapter lets you plug in a shotgun or lavalier mic. I use a Rode VideoMic Me-L — the difference is night and day. No more “what did you say?” in my videos.

• Best for: Vlogging, interviews, windy environments
• Pro tip: Use a windscreen on the mic — even a small one helps.
• Watch out: The adapter adds bulk. It’s not ideal for helmet mounts.

Wi-Fi Remote Control: Frame Your Shots

The Mi Wi-Fi remote pairs with your camera and lets you start/stop recording, change modes, and even preview the frame on your phone. I use it for solo shoots — no more running back and forth.

• Best for: Solo filming, group shots, time-lapses
• Pro tip: Pair it before you leave home — it can be finicky in cold weather.
• Watch out: The remote’s battery life is short. Carry a spare.

HDMI Cable for Live Streaming

If you’re streaming to YouTube or Instagram, the Mi HDMI output cable lets you connect to a laptop or encoder. I use it with OBS — the 4K feed looks amazing.

• Best for: Live streaming, professional setups
• Pro tip: Use a 6-foot cable for flexibility.
• Watch out: The camera can overheat during long streams. Use a fan or take breaks.

5. Storage & Data: Never Miss a Shot Due to a Full Card

4K video eats up storage fast. A 64GB card holds about 90 minutes — not enough for a full day of filming.

High-Speed MicroSD Cards

Use a UHS-I U3 or UHS-II card with at least 128GB. I use a SanDisk Extreme 256GB — it’s fast, reliable, and survives extreme temps. I’ve used it from -10°C to 50°C — no issues.

• Best for: Long shoots, travel
• Pro tip: Label your cards — “Day 1,” “Day 2” — so you don’t mix them up.
• Watch out: Cheap cards can corrupt. Stick with SanDisk, Samsung, or Lexar.

Card Reader & Backup Drive

Transfer files fast with a USB 3.0 card reader. I pair it with a Seagate 1TB portable SSD — I can back up a full day of footage in 10 minutes.

• Best for: Travel, editing on the go
• Pro tip: Back up to the cloud if you have signal — extra protection.
• Watch out: Don’t edit directly from the card. Copy files to your computer first.

6. Bonus Accessories: The Little Things That Make a Big Difference

These aren’t essential, but they’re worth every penny.

Anti-Fog Inserts

Use them in humid or cold environments. I put them in my housing before a rainforest hike — no fogging.

Lens Cleaning Kit

A microfiber cloth, lens pen, and cleaning solution keep your lens spotless. I carry a small kit in my bag.

Carrying Case

A padded case protects your gear. I use a Lowepro Apex 10 — it fits the camera, 2 batteries, and 2 mounts.
