Why I Took the Akaso EK7000 4K Action Camera Underwater Charging Case on My Last Dive Trip

Let me set the scene: I was 15 feet underwater, snorkeling through a coral reef in the Philippines, when my Akaso EK7000 4K action camera suddenly flashed a low-battery warning. I had planned to capture a full 30-minute dive, but I was only 10 minutes in. I panicked—my backup battery was back on the boat, and I had no way to recharge. That moment stuck with me. When I heard about the Akaso EK7000 4K action camera underwater charging case, I was skeptical. Could a charging case really work *underwater*? After testing it on my next tropical getaway, I’m ready to share the honest truth.

Action cameras like the Akaso EK7000 are fantastic for adventurers, divers, and vloggers, but their biggest weakness is battery life—especially when you’re off-grid or deep underwater. The underwater charging case promises to fix that. But does it deliver? In this review, I’ll walk you through my hands-on experience, the real-world pros and cons, and whether this accessory is worth adding to your gear bag. Whether you’re a scuba diver, a kayaker, or someone who loves filming in wet environments, this could be the game-changer you’ve been waiting for.

What Is the Akaso EK7000 4K Action Camera Underwater Charging Case?

Understanding the Concept

The Akaso EK7000 4K action camera underwater charging case is a specialized waterproof housing designed not just to protect your camera, but to actively charge it while submerged. Unlike standard cases that simply shield the camera from water, this one includes an internal battery and a charging mechanism that powers your EK7000 without removing it from the case. Think of it as a portable power bank built into a rugged, pressure-resistant shell.

It’s compatible only with the Akaso EK7000 and EK7000 Pro models, so if you’re using a different action camera, this won’t work for you. But for EK7000 owners, it’s a unique solution to a common problem: running out of juice during long shoots.

Key Features at a Glance

• Waterproof up to 40 meters (130 feet) – suitable for snorkeling, scuba diving, and deep-water filming
• Built-in 2600mAh battery – provides up to 2 full recharges for the EK7000’s 1050mAh battery
• Underwater charging – charge your camera while filming, no need to surface
• Transparent polycarbonate housing – clear view for framing shots
• Secure locking mechanism – prevents accidental opening
• External charging port – recharge the case via USB-C when on land

What makes this case stand out is the sealed charging port inside the housing. Once the camera is locked in, you can activate charging via a button on the case. The port is protected by a rubber seal, so water can’t get in—even at depth.

Who Should Consider It?

This case isn’t for everyone. If you’re a casual user who films for 10 minutes at a time, you probably don’t need it. But if you’re:

• A scuba diver recording long dives
• A freediver capturing extended underwater sequences
• A travel vlogger filming all day in wet environments
• Someone who hates swapping batteries mid-adventure

…then the Akaso EK7000 4K action camera underwater charging case could be a smart investment. It eliminates the need to carry multiple batteries or risk missing the perfect shot due to power loss.

Real-World Performance: How It Held Up on My Dives

First Impressions & Setup

When the case arrived, I was surprised by its weight—about 30% heavier than the standard Akaso waterproof housing. That’s due to the internal battery and reinforced seals. The build feels solid, not flimsy. The polycarbonate is thick, and the locking mechanism clicks securely into place.

Setting it up was simple. I placed my EK7000 into the case, aligned the charging pins (they only fit one way), and locked the back. The camera powered on immediately—no issues. I tested the charging function on land first: pressed the external button, and the LED on the case blinked blue (charging) and green (fully charged). The process took about 90 minutes to fully charge the camera from 10%.

Underwater Charging Test – The Moment of Truth

I took it on a 45-minute scuba dive in Bali. My EK7000 started at 85% battery. After 20 minutes of filming, it dropped to 50%. I pressed the charging button on the case, and the LED turned blue. Within 15 minutes, the battery was back to 80%. I filmed another 25 minutes, and when I surfaced, the camera still had 40%—plenty for the boat ride back.

Here’s what impressed me:

• Charging worked at 30 meters depth – no lag, no interruptions
• No fogging or leaks – the seals held perfectly
• Stable footage – no interference from the charging process

But there was one hiccup: the charging button is small and recessed. In thick diving gloves, it was a bit tricky to press. I had to use a finger or a tool (like a pen cap) to activate it. Not a dealbreaker, but worth noting.

Video Quality & Audio

I filmed in 4K/30fps with the EK7000’s built-in stabilization. The case didn’t affect video quality—colors were vibrant, and the clarity was excellent. However, the microphone is muffled underwater, just like with any housing. If you need crisp audio, consider using an external mic (though that defeats the waterproof benefit).

One tip: film with the camera’s screen off to save power. The case’s transparent back lets you frame shots using the camera’s front screen or just by pointing it. I used the Akaso app on my phone to check framing before diving—super helpful.

Pros and Cons: The Honest Breakdown

The Good Stuff

Let’s start with what works well. The Akaso EK7000 4K action camera underwater charging case delivers on its core promise: keeping your camera powered underwater.

• Extended filming time – I gained an extra 20–25 minutes of 4K recording per dive, thanks to the case’s battery. That’s huge for long dives or back-to-back shoots.
• No battery swaps – I didn’t have to surface, open the case, or risk water damage. Just press a button and keep filming.
• Reliable waterproofing – I tested it in saltwater, freshwater, and even a waterfall. Zero leaks after 10+ dives.
• Compact and portable – fits easily in a dive bag. The included mount works with standard GoPro-style accessories.
• Fast charging on land – the case recharges fully in about 3 hours via USB-C.

For me, the biggest win was peace of mind. I no longer had to obsess over battery percentages or cut dives short.

Where It Falls Short

No product is perfect, and this case has a few limitations.

• Only works with EK7000/EK7000 Pro – if you upgrade cameras, you’ll need a new case.
• Charging button is hard to press with gloves – as mentioned earlier, this can be frustrating in cold water.
• Added weight and bulk – the case makes the camera heavier, which might affect balance if you’re using a selfie stick or gimbal.
• No wireless charging – you can’t charge the case remotely. It must be plugged in.
• Microphone muffled underwater – not unique to this case, but still a limitation for vloggers.

One thing I wish it had: a battery level indicator on the outside. Right now, you have to open the case or use the Akaso app to check the case’s battery. A simple LED display would be a nice upgrade.

Is the Price Justified?

The case retails for around $80–$100, which is 2–3 times the cost of a standard waterproof housing. Is it worth it? For frequent divers or professionals, yes. The time saved, the extended battery life, and the convenience make it a solid long-term investment. But if you only dive a few times a year, you might be better off buying extra batteries.

Comparing the Underwater Charging Case to Alternatives

Standard Waterproof Housing vs. Charging Case

The standard Akaso waterproof case costs about $30 and offers the same 40m depth rating. It’s lighter and simpler. But it has no battery—just protection. If you’re filming for 15 minutes or less, it’s fine. But for longer sessions, the charging case is far more practical.

Here’s a quick comparison:

Feature	Standard Case	Underwater Charging Case
Depth Rating	40m	40m
Battery	None	2600mAh (2x camera recharge)
Underwater Charging	No	Yes
Weight	120g	180g
Price	$30	$90

Other Charging Solutions

Are there other ways to keep your EK7000 charged underwater?

• External battery packs with waterproof bags – risky and bulky. You’d need to run a cable from the bag to the camera, which can leak.
• Spare batteries – Akaso sells 1050mAh batteries for $15 each. But swapping them underwater is nearly impossible without a dry bag.
• Solar chargers – only useful on land or at the surface.

None of these match the convenience of the Akaso EK7000 4K action camera underwater charging case. It’s the only solution that lets you charge *while* filming, *without* surfacing.

Practical Tips for Getting the Most Out of Your Charging Case

Pre-Dive Prep

To avoid issues, do these before every dive:

• Fully charge both the case and camera – I use a USB-C power bank to charge both overnight.
• Test the charging function on land – make sure the pins connect and the LED lights work.
• Clean the seals – wipe the rubber gaskets with a soft cloth to remove salt or sand.
• Use the Akaso app to check battery levels – it shows the camera’s battery and (indirectly) the case’s charge.

Underwater Charging Best Practices

• Start charging before the battery drops below 30% – this ensures a full recharge before it dies.
• Press the button firmly – if it doesn’t respond, try again. Sometimes the seal needs a moment to equalize pressure.
• Avoid charging in direct sunlight – heat can reduce battery efficiency.
• Don’t charge while recording 4K/60fps – this drains power faster. Stick to 30fps for longer sessions.

Post-Dive Care

After your dive:

• Rinse the case with fresh water – especially if you were in saltwater.
• Open the case to air dry – this prevents mold or corrosion.
• Recharge the case within 24 hours – lithium batteries last longer when kept charged.

One pro tip: use a desiccant pack inside the case when storing it long-term. It absorbs moisture and keeps the seals fresh.

Final Verdict: Is the Akaso EK7000 Underwater Charging Case Worth It?

After months of testing, I can confidently say the Akaso EK7000 4K action camera underwater charging case is one of the most practical accessories I’ve used for underwater filming. It solved my biggest pain point—battery anxiety—and let me focus on capturing amazing moments, not managing power.

Yes, it has quirks. The charging button could be easier to use with gloves, and the price is steep compared to a standard case. But for anyone who films underwater for more than 20 minutes at a time, the benefits far outweigh the drawbacks. It’s reliable, well-built, and genuinely innovative.

If you’re a diver, snorkeler, or adventure filmmaker who relies on the EK7000, this case is a smart upgrade. It’s not just a housing—it’s a power solution. And in the world of action cameras, where every second counts, that makes all the difference.

So, would I recommend it? Absolutely. Just remember: it’s not a magic fix for everything. You’ll still need to manage settings, lighting, and storage. But when it comes to power, the Akaso EK7000 4K action camera underwater charging case has your back—literally, and figuratively, underwater.
