These key add-ons boost durability, versatility, and performance, making your action cam ready for anything.

Key Takeaways

• Essential mounts: Secure your camera with adhesive or clamp mounts for stable shots.
• Extra batteries: Extend recording time with high-capacity Sony NP-BX1 replacements.

Why the Sony HDR AS20 B Deserves the Right Gear

Let’s be real—owning a Sony HDR AS20 B action video camera is exciting. It’s compact, delivers crisp 1080p video, and handles shaky adventures like a champ. But here’s the thing: without the right Sony HDR AS20 B action video camera accessories, you’re only using half its potential. I learned this the hard way during a hiking trip last summer. I had the camera, but no extra battery, no waterproof case, and no way to stabilize it on my helmet. By the time I reached the summit, the battery died mid-recording, and my shaky hands made the footage look like a 90s camcorder demo. Lesson learned.

That trip taught me a golden rule: the camera is just the beginning. The real magic happens when you pair it with the right accessories. Whether you’re chasing adrenaline on a mountain bike, capturing family moments at the beach, or documenting a DIY project, the right add-ons can turn good footage into great memories. In this guide, we’ll dive into the must-have Sony HDR AS20 B action video camera accessories that’ll make your videos smoother, longer, and way more professional—without breaking the bank.

Essential Power Solutions for Longer Recording

Nothing kills the vibe like a dead battery. The Sony HDR AS20 B comes with a rechargeable NP-BX1 battery, but its 1.5–2 hour life span (depending on usage) isn’t enough for full-day adventures. Here’s how to stay powered up.

Extra Batteries: Your Best Friend

Always carry at least one spare NP-BX1 battery. I keep two in my gear bag: one in the camera, one charging, and one as backup. Why? Because Murphy’s Law applies to batteries. They’ll die right when you’re about to film a once-in-a-lifetime moment. Pro tip: label your batteries (e.g., “Primary,” “Backup”) with a waterproof marker to avoid confusion mid-hike.

• Original Sony NP-BX1: Reliable but pricey (~$30). Worth it for peace of mind.
• Third-party options (e.g., Kastar, Wasabi): Cheaper (~$15–20) but check reviews. I’ve had mixed luck—some last just as long, others die in 30 minutes.

Portable Chargers & USB Power Banks

The AS20 B charges via USB, so a power bank is a game-changer. I use a 10,000mAh Anker PowerCore. It’s compact, charges the camera twice, and doubles as a phone charger. For longer trips, I pack a solar-powered bank (like the BigBlue 28W). Just don’t rely on it in cloudy weather—solar is slow.

Real-world tip: Turn off Wi-Fi and LCD screen while charging to speed things up. A fully drained battery takes ~2.5 hours to charge via USB.

Car & Wall Chargers

For road trips, a 12V car charger (like the Sony AC-UD10) keeps your batteries topped up. At home, a dual-port USB wall charger lets you charge two batteries at once. I keep one in my office and another in my travel kit.

Stabilization & Mounting: Get Steady, Get Smooth

The AS20 B has decent in-camera stabilization, but shaky footage can still ruin a great moment. These accessories fix that.

Helmet & Handlebar Mounts

For biking, climbing, or skiing, a helmet mount is a must. The Sony AKA-HE1 helmet mount is lightweight and adjustable, but it’s pricey (~$40). I found a cheaper alternative: the ActionMount Universal Helmet Mount (~$15). It works just as well and fits the AS20 B perfectly.

For bikes or motorcycles, the Sony AKA-HM1 handlebar mount is rock-solid. I tested it on a bumpy mountain trail—zero wobble. Just make sure to tighten the clamp with a wrench, not your hands.

Tripods & Selfie Sticks

Need hands-free filming? A mini tripod (like the Joby GorillaPod) is perfect for tabletop shots or vlogging. I use the Sony VCT-55LH tripod adapter, which lets you attach the AS20 B to any standard tripod. For selfies, a telescopic selfie stick (e.g., GoPro 3-Way Grip) works great. The AS20 B’s tripod socket is on the side, so it’s easy to adjust angles.

Chest Harnesses & Wrist Straps

For immersive POV shots (think: kayaking or skiing), a chest harness (like the Sony AKA-CM1) is a lifesaver. It’s more stable than a helmet mount and keeps the camera at eye level. For quick access, I use a wrist strap (e.g., Peak Design Cuff) when filming on the move. It prevents drops—trust me, I’ve tested this the hard way.

Waterproofing & Protection: Shoot Anywhere, Anytime

The AS20 B isn’t natively waterproof, so a housing is non-negotiable for water sports, rain, or dusty environments.

Underwater Housings

The Sony MPK-AS3 is the official waterproof case, rated for 60 meters (197 feet). It’s bulky but reliable. I used it for snorkeling in Hawaii—zero leaks, and the buttons were easy to press underwater. For shallow water, a cheaper alternative like the DiCAPac WP-S10 (~$30) works. It’s a flexible case with a touchscreen-compatible window, but don’t take it deeper than 10 feet.

Dustproof & Shockproof Cases

For desert hikes or off-road biking, a rugged case (e.g., Pelican 1010) protects your camera from sand, drops, and vibrations. I keep mine in a padded backpack with silica gel packets to fight humidity.

Lens Covers & Filters

The AS20 B’s lens is exposed, so a Sony LCJ-HA lens cap is essential. For glare reduction, a UV filter (e.g., Hoya HMC UV) helps. I noticed a big difference filming at sunset—less lens flare, more vibrant colors.

Audio Upgrades: Clear Sound, No Background Noise

The built-in mic is okay, but wind noise and muffled voices are common. Here’s how to fix it.

External Microphones

The Sony ECM-AW4 wireless mic clips to your shirt and connects via Bluetooth. It’s pricey (~$100), but the audio is crystal clear. For a budget option, the Rode VideoMicro (~$50) mounts on the camera and cuts wind noise with its furry windshield.

Wind Muffs & Dead Cats

For outdoor shoots, a “dead cat” (yes, that’s the real name) windshield is a must. The Furry Windshield for Sony AS20 (~$15) reduced wind noise by 80% during a windy beach shoot. Pro tip: attach it with a rubber band if the clip is too tight.

Audio Recorders (For Pro Use)

If you’re serious about sound, pair the AS20 B with a Zoom H1n recorder. Record audio separately, then sync it in editing. I did this for a travel vlog—the difference was night and day.

Storage & Connectivity: Never Lose a Shot

Running out of storage or struggling to transfer files? These accessories solve both.

High-Speed Memory Cards

The AS20 B uses microSD cards (up to 128GB). I use a SanDisk Extreme 64GB (U3, 160MB/s). It handles 1080p/60fps without buffering. Avoid cheap cards—they’ll corrupt your footage. Test yours with H2testw (free software) to verify capacity.

Card Readers & Adapters

A USB-C card reader (e.g., Anker 2-in-1) lets you transfer files to your phone or laptop in seconds. For older computers, an SD card adapter (like the Sony MRW-E90) works too.

Wi-Fi & Remote Control

The AS20 B has built-in Wi-Fi, but the Sony RM-LVR1 remote control (~$50) is better for group shots or self-filming. It pairs instantly and works up to 10 meters away. I used it for a family picnic—no more sprinting back to start recording.

Bonus Accessories: The Little Things That Matter

These extras aren’t essential, but they make filming easier and more fun.

Cleaning Kits

A microfiber cloth and lens cleaning pen keep your camera spotless. I keep mine in a small pouch with a blower (for dust) and a UV filter wipe.

Backpack & Storage Bags

A padded action camera bag (e.g., Lowepro Apex 10) organizes your gear. I use it for hiking—fits the camera, mounts, batteries, and cables in one compact case.

Editing Software (Not an Accessory, But Helpful)

For quick edits, Sony’s PlayMemories Mobile app lets you trim clips on your phone. For advanced editing, try Adobe Premiere Rush (free tier available).

Accessory Comparison: What’s Worth It?

Here’s a quick breakdown of top accessories and their value:

Accessory	Best For	Price Range	Verdict
NP-BX1 Battery (Spare)	Extended recording	$15–30	Must-have for all users
