Best Travel Case for Anker 737 Power Bank
The Anker 737 (PowerCore 24K) is an absolute beast for photographers on location, but its tall, “brick” form factor makes it a nightmare to pack safely. I’ve seen too many of these premium power banks end up with cracked screens or scuffed casings after a rough flight. Finding a dedicated case that accommodates its unique dimensions and high-speed cables is essential. Our top pick, the RLSOCO Hard Case, offers the precise molding required to keep this heavy-duty battery stationary and secure during transit.

Best Travel Case for Anker 737 Power Bank: Detailed Reviews
RLSOCO Hard Case View on Amazon
The RLSOCO Hard Case is the gold standard for the Anker 737. Unlike generic pouches, this case features a custom-molded interior that prevents the heavy battery from sliding around—a crucial feature given that the 737 weighs over 1.3 pounds. During my last landscape shoot in Iceland, the rigid EVA exterior took several knocks in my checked luggage without a single scratch to the power bank’s sensitive LED display. The mesh pocket in the lid is surprisingly deep, comfortably housing a 140W USB-C cable and even a small wall plug. The zipper action is incredibly smooth, which I always appreciate when I’m fumbling for power in a dark terminal. While it adds a bit of bulk to your kit, the peace of mind it provides for a $150 battery is worth every extra ounce.

Khanka Hard Travel Case View on Amazon
If you don’t need the extreme heavy-duty molding of the RLSOCO, the Khanka Hard Travel Case is a fantastic middle ground. It balances affordability with high-quality materials, featuring a soft velvet lining that protects the Anker 737’s glossy front panel from micro-abrasions. I found the fit to be snug but not restrictive; you won’t struggle to zip it shut even with a thick braided cable tucked inside. The exterior hand strap is a nice touch for quick transitions between bags. It lacks the “tank-like” feel of more expensive options, but for the average user who just wants to toss their battery into a backpack without worry, it’s the most sensible choice. The classic black finish and minimalist design ensure it doesn’t look out of place in a professional camera bag or a corporate briefcase.

Hermitshell Hard Travel Case View on Amazon
The Hermitshell Hard Travel Case is for those who spent their budget on the power bank itself and want no-frills protection for the remainder. It’s significantly lighter than the other cases on this list, which is a benefit if you’re already hitting your airline’s weight limit. The build quality is honest—it’s a basic EVA shell with a standard zipper. You won’t get the premium “feel” or the custom interior molding of the RLSOCO, but it will absolutely prevent keys from scratching the screen or light rain from getting into the ports. One limitation to keep in mind is that the internal space is tighter; if you use extra-long 10ft cables, you might find it a bit of a squeeze. However, for a standard 3ft charging cable, it works perfectly well and represents the best value for money in the budget category.

Smatree Hard Shell Carrying Case View on Amazon
The Smatree Hard Shell is built like a miniature Pelican case for your electronics. For photographers who often work in rugged environments—think dusty trails or humid jungles—the Smatree offers an extra layer of structural rigidity that others don’t. The outer fabric is more abrasion-resistant, and the carabiner loop is reinforced, allowing you to clip the battery to the outside of your pack for easy access during a shoot. I’ve found that the internal elastic straps are much tighter on this model, ensuring the Anker 737 doesn’t budge even during heavy vibration (like in the back of a 4×4). It’s the “pro” choice for those who treat their gear roughly. While it’s the most expensive on the list, the build quality justifies the price for anyone who relies on their power bank for mission-critical shoots.

BAGSMART Electronic Organizer View on Amazon
Not everyone wants a dedicated single-purpose case. If you’re like me and carry a plethora of SD cards, ND filters, and multiple USB-C cables, the BAGSMART Electronic Organizer is a brilliant alternative. While it’s not molded specifically for the Anker 737, the medium size fits the battery perfectly in the main padded compartment. The beauty here is the organization; you can keep your 737, a wall charger, and all your camera’s tethering cables in one place. It’s a soft-sided case, so it doesn’t offer the same crush protection as the RLSOCO, but it’s much better for streamlining your workflow. You’ll notice that having everything in one “tech pouch” makes airport security much faster. It’s the best choice for the organized creative who values workflow efficiency over pure armor-plating.

Frequently Asked Questions
Will the Anker 140W wall charger fit inside these cases?
Most dedicated cases like the RLSOCO and Khanka are designed specifically for the battery and a cable. While a small GaN charger might squeeze into the RLSOCO, the standard Anker 140W brick is quite large and usually requires a separate compartment. If you need to carry both together, the BAGSMART Organizer is a better bet as it has larger, flexible pockets designed for bulky wall adapters.
Is the Anker 737 safe to carry in a hardshell case on a plane?
Yes, absolutely. In fact, it’s recommended. TSA requires lithium batteries to be in carry-on luggage, and a hardshell case provides the necessary protection against short circuits or physical damage. The Anker 737 is 86.4Wh, which is well under the 100Wh limit for most airlines, making it perfectly legal for air travel. The case simply ensures it doesn’t get crushed in the overhead bin.
Do these cases help with heat dissipation while charging?
No, you should never charge your devices while the Anker 737 is inside a closed travel case. The 737 can generate significant heat when outputting 140W, and EVA foam is an insulator. Always remove the battery from the case when in use to ensure proper airflow and to prevent the power bank’s thermal protection from kicking in and slowing down your charge speeds.
How water-resistant are these cases?
Most of the cases listed, particularly the Smatree and RLSOCO, are water-resistant but not waterproof. They will easily survive a splash or a brief walk through the rain, but they cannot be submerged. The zippers are usually the weakest point for water entry. If you’re going to be on a boat or in extreme wet weather, consider placing the hardshell case inside a dry bag.
Can I use a generic “large” power bank sleeve instead?
You can, but it’s not ideal. Generic sleeves are often designed for flat, smartphone-style batteries. Because the Anker 737 is shaped like a block, it will stretch a flat sleeve awkwardly, leaving the corners exposed and the screen vulnerable. A dedicated “brick” style case ensures that all six sides of the battery are equally protected from impact and pressure.
Final Verdict
For most users, the RLSOCO Hard Case is the definitive choice; its custom molding is simply too good to pass up for a battery this heavy. If you’re a professional photographer frequently in the field, the Smatree offers that extra bit of ruggedness. However, if you’re just looking for a reliable way to get your Anker 737 from A to B without the screen getting scratched, the Khanka provides excellent value for your money.
