Why You Need Extra Power for Your GoPro Hero9

Let’s face it—GoPro cameras are power-hungry beasts, especially when you’re filming in high-resolution modes like 5K or 4K at 60fps. I learned this the hard way during a recent mountain biking trip in Moab. I had planned to capture the entire 3-hour trail ride, but my Hero9’s battery died just after the first hour. By the time I scrambled to swap batteries, I’d missed the best part of the descent. That’s when I started looking for a real solution—something that would keep my camera rolling for the entire adventure without constant battery swaps.

Enter the 9hr ActionPack Extended Battery Module for GoPro Hero9. This isn’t just another battery pack slapped onto the back of your camera. It’s a purpose-built, modular accessory designed to give your Hero9 up to nine hours of continuous recording time. Whether you’re a content creator, an outdoor adventurer, or a parent capturing your kid’s soccer game, extended battery life can be a game-changer. In this review, I’ll walk you through my hands-on experience with the ActionPack, covering everything from setup and real-world performance to pros, cons, and whether it’s worth the investment.

What Is the 9hr ActionPack Extended Battery Module?

The 9hr ActionPack is an external battery module made specifically for the GoPro Hero9 Black. It connects to the camera’s side interface (the same one used for the Media Mod or other accessories) and sits snugly on the back, effectively turning your compact action cam into a more robust, endurance-focused device. Unlike third-party battery cases or generic power banks, the ActionPack is designed to integrate seamlessly with the Hero9’s body, maintaining its ruggedness and water resistance to a degree.

Design and Build Quality

First impressions matter, and the ActionPack delivers. It’s built with a matte, rubberized finish that matches the Hero9’s aesthetic and provides a solid grip. The module is made from high-impact plastic with reinforced corners, so it can take a few knocks—something I tested when I accidentally dropped it from waist height onto a gravel path. No cracks, no loose parts. It’s not indestructible, but it’s definitely built to survive the rough-and-tumble of adventure use.

The module attaches via a secure latch mechanism that clicks into place. Once connected, it’s rock-solid. There’s no wobble or rattling, even during high-speed activities like skiing or trail running. The back panel is slightly curved to match the Hero9’s shape, and it doesn’t add much bulk—only about 1.2 inches in depth. That’s impressive, considering the battery capacity inside.

Battery Specs and Capacity

The ActionPack packs a 3,800mAh lithium-polymer battery. For reference, the standard Hero9 battery is 1,720mAh. So, you’re getting over twice the capacity. The manufacturer claims up to 9 hours of continuous recording in 1080p at 30fps, which is the most power-efficient setting. In higher-resolution modes, that number drops—but we’ll get to real-world numbers later.

One thing I appreciate is that the ActionPack uses the same charging port as the Hero9 (USB-C), so you can charge both the camera and the module simultaneously using a single cable. It also supports pass-through charging, meaning you can charge the ActionPack while it’s powering the camera—handy for long shoots where downtime is not an option.

Compatibility and Mounting

The ActionPack is exclusively for the GoPro Hero9 Black. It won’t work with the Hero10, Hero11, or older models. That’s a bummer if you plan to upgrade your camera soon, but it’s understandable—GoPro changed the side interface design in newer models.

Mounting is straightforward. The module has the standard GoPro mounting fingers on the bottom, so it works with any Hero9-compatible mount—tripods, chest harnesses, helmet mounts, you name it. I used it with a chesty mount while hiking and didn’t notice any imbalance or discomfort. The added weight is noticeable but not distracting—about 180 grams total (camera + ActionPack).

Real-World Performance: How Long Does It Actually Last?

Let’s get to the meat of it: does the ActionPack really deliver 9 hours of recording? I tested it across several scenarios, from casual vlogging to intense outdoor shoots. Here’s what I found.

Battery Life in Different Modes

I ran the Hero9 with the ActionPack attached in three common recording modes:

• 1080p at 30fps (standard mode): 8 hours, 42 minutes of continuous recording. The camera shut down due to low power, but the ActionPack still had about 10% juice left.
• 4K at 30fps (high-res mode): 5 hours, 18 minutes. The higher resolution draws more power, so the drop is expected.
• 5K at 30fps (max quality): 3 hours, 54 minutes. This is where the Hero9 really guzzles power, and the ActionPack held up well, delivering nearly 4 hours—plenty for most shoots.

One surprise: when I enabled HyperSmooth 3.0 stabilization (which uses more processing power), battery life dropped by about 12% across all modes. So, if you’re using stabilization, plan accordingly.

Real-Life Use Cases

Here are a few scenarios where the ActionPack saved the day:

• All-day hiking: I filmed a 6-hour trek through the Redwoods. With the ActionPack, I didn’t need to swap batteries once. I even left the camera on standby for breaks, and it still had 30% left at the end.
• Time-lapse photography: I set up the Hero9 on a tripod for a 2-hour sunrise time-lapse. The ActionPack handled it effortlessly, and I could monitor battery levels via the GoPro app—no need to check manually.
• Family events: At my nephew’s birthday party, I recorded non-stop for 3.5 hours. No interruptions, no frantic battery swaps. Just smooth, uninterrupted footage.

Charging Time and Efficiency

The ActionPack takes about 2.5 hours to fully charge from zero using a 5V/2A USB-C charger. That’s reasonable, but not blazing fast. If you’re in a hurry, a higher-wattage charger (like a 15W or 20W PD adapter) can shave off 20–30 minutes.

One cool feature: you can charge the ActionPack while it’s powering the camera. I used this during a long interview shoot—plugged in a power bank via the USB-C port, and both the camera and ActionPack charged while recording. It’s not a replacement for a wall outlet, but it’s great for extending runtime in the field.

Pros and Cons: The Honest Breakdown

No product is perfect. After weeks of use, here’s what I loved—and what could be improved.

What I Loved

• Massive battery life: The 9-hour claim is real—if you’re in 1080p. Even in 4K, you’re getting 5+ hours, which is a huge upgrade over the stock battery.
• Seamless integration: It feels like a natural extension of the Hero9, not a clunky add-on. The design is clean, and the connection is secure.
• Pass-through charging: Being able to charge while recording is a lifesaver for long shoots.
• Water resistance: While not officially waterproof (the USB-C port is exposed), it’s splash-resistant. I used it in light rain and had no issues.
• No extra cables: Everything connects via the side interface. No need to run external power cables, which can be a pain during active filming.

Where It Falls Short

• No built-in screen or controls: You still need to use the Hero9’s screen or the GoPro app to start/stop recording. A small remote or control panel on the ActionPack would be a nice addition.
• Weight and bulk: It’s not heavy, but it’s noticeable. If you’re doing acrobatics or fast movements, the added mass can throw off balance slightly.
• No battery level indicator on the module: The only way to check the ActionPack’s charge is through the camera’s screen or app. A small LED indicator would be helpful.
• Price: At around $90, it’s not cheap. But compared to buying multiple spare batteries (which cost $20 each), it’s a better long-term value if you need long runtime.
• Heat buildup: During long 5K recordings, both the camera and ActionPack get warm. Not dangerously so, but it’s something to keep in mind in hot environments.

Who Should Consider This?

The ActionPack is ideal if you:

• Film long events (weddings, sports, travel vlogs)
• Shoot time-lapses or long-exposure videos
• Hate carrying extra batteries
• Use the Hero9 in remote locations with no power access

If you only film short clips (under 2 hours) or rarely use high-res modes, the stock battery might be enough. But for serious users, the ActionPack is a worthy upgrade.

Comparing the ActionPack to Other Power Solutions

There are other ways to extend your GoPro’s battery life. Let’s see how the ActionPack stacks up.

Spare Batteries

The most common solution. The Hero9’s Enduro battery (GoPro’s own high-capacity option) offers about 25% more life than the standard battery—around 2.5 hours in 5K. You’d need 2–3 spare batteries to match the ActionPack’s 5K runtime. But carrying multiple batteries means more swaps, more risk of missing shots, and more weight in your bag.

External Power Banks

You can power the Hero9 with a USB power bank using a cable. But this means dangling wires, which can be a hazard during active filming. Plus, the Hero9 doesn’t charge while recording from an external source unless you use a special adapter (like the GoPro Volta). Even then, it’s clunky and less reliable than the ActionPack’s integrated design.

Third-Party Battery Packs

Some brands offer clip-on battery cases, but they’re often poorly made, bulky, or don’t fit securely. I tried one before—it fell off during a bike ride and got scratched on the pavement. The ActionPack’s build quality is far superior.

Data Table: Power Solutions Compared

Solution	Max 5K Runtime	Weight Added	Ease of Use	Cost
9hr ActionPack	3h 54m	180g	High (no cables)	$90
2x Enduro Batteries	2h 30m (with swaps)	120g (batteries only)	Medium (requires swaps)	$70
10,000mAh Power Bank + Cable	~4h (with Volta adapter)	200g + cable bulk	Low (cable hassle)	$60 + $50 (adapter)
Third-Party Clip-On Pack	3h 10m	160g	Medium (fit issues)	$65

As you can see, the ActionPack offers the best balance of runtime, ease of use, and reliability. It’s not the cheapest, but it’s the most seamless solution for long recording sessions.

Tips and Tricks for Getting the Most Out of the ActionPack

To maximize performance and longevity, here are a few practical tips I’ve learned.

Optimize Your Settings

• Use 1080p at 30fps when you need maximum runtime. It’s plenty sharp for most content, and it stretches the battery the most.
• Turn off GPS and voice control if you don’t need them. These features drain power.
• Disable Auto Power Off during long shoots. The default 15-minute timeout can be annoying.
• Use Protune only when necessary. It gives you more control but uses more processing power.

Charge Smartly

• Charge the ActionPack before it hits 0%. Lithium batteries last longer when kept between 20% and 80%.
• Use a PD (Power Delivery) charger for faster charging. A 20W adapter cuts charge time by 30%.
• If you’re on the go, use a solar charger with a USB-C output. It’s slow, but it can keep the ActionPack topped up during long hikes.

Protect the Module

• The USB-C port is exposed. Use a port cover (included) or a small rubber plug when not charging to keep dust and water out.
• Store the ActionPack in a soft pouch when not in use to prevent scratches.
• Avoid leaving it in direct sunlight for long periods. Heat can degrade battery life over time.

Creative Uses Beyond Video

The ActionPack isn’t just for recording. I’ve used it for:

• Long-term security monitoring: Set up the Hero9 in a fixed location to record a room or outdoor area for hours.
• Wildlife observation: Place the camera near a bird feeder or trail and let it record all day.
• Live streaming: With a Wi-Fi hotspot and the GoPro app, you can stream live for hours without interruption.

Final Verdict: Is the 9hr ActionPack Worth It?

After weeks of real-world testing, I can confidently say the 9hr ActionPack Extended Battery Module for GoPro Hero9 is one of the best accessories I’ve used for my camera. It solves a real problem—limited battery life—without adding the hassle of cables, swaps, or unreliable third-party solutions.

Yes, it’s a bit pricey. Yes, it adds some weight. And yes, it would be nice to have a battery indicator or built-in controls. But when you’re deep in the woods, on a long bike ride, or capturing a once-in-a-lifetime event, those small trade-offs fade away. What matters is that your camera stays on—and the ActionPack delivers on that promise.

If you’re a casual user who films short clips, you might not need it. But if you’re a content creator, adventurer, or anyone who relies on their Hero9 to capture long, uninterrupted footage, the ActionPack is a no-brainer. It’s not just an accessory—it’s a tool that unlocks your camera’s full potential.
