Best Travel Case for Anker 737 Power Bank
The Anker 737 is a beast of a power bank, but its massive 24,000mAh capacity comes with a literal weight: it’s a heavy, dense brick with a vulnerable smart display. In my time shooting time-lapses in the field, I’ve seen these displays get scuffed by stray tripod plates in a bag. Finding the right travel case isn’t just about storage; it’s about protecting that $150 investment. I’ve tested several options, and the Hermitshell Hard Case stands out as the definitive choice for most users.

Best Travel Case for Anker 737 Power Bank: Detailed Reviews
Hermitshell Hard Travel Case View on Amazon View on B&H
The Hermitshell Hard Travel Case is specifically engineered for the Anker 737’s unique “coke-can” dimensions. When I first slid my 737 into this case, I was immediately impressed by the lack of “wiggle room.” The interior is lined with a soft velvet-like material that prevents the glossy screen from micro-scratches—a common issue with cheaper nylon bags. The outer EVA shell is rigid enough to survive a drop from waist height onto concrete, which is vital given how heavy the Anker 737 is. There is a mesh pocket in the lid that comfortably holds the 140W USB-C cable and even a small wall charger like the Anker 717. My only minor gripe is that the zipper can feel a bit stiff initially, but it breaks in quickly. It’s the gold standard for protecting high-end power banks during transit.

Khanka Hard Travel Case View on Amazon View on B&H
If you want 90% of the protection of a premium case at a lower price point, the Khanka is the way to go. It offers a slightly more utilitarian aesthetic but doesn’t skimp on the build quality. I particularly appreciate the elastic strap inside; it keeps the power bank from shifting if the case isn’t fully packed. While the Anker 737 fits snugly, there’s just a tiny bit more clearance than the Hermitshell, which some users might prefer if they use a silicone sleeve on the power bank itself. The exterior fabric is water-resistant, which saved my gear during a light drizzle on a shoot in Seattle. It doesn’t feel quite as “premium” as the RLSOCO, but for the price, the value proposition is unbeatable for those who just need a reliable home for their battery.

GLCON Portable Protection Case View on Amazon View on B&H
The GLCON is a generic electronics organizer that happens to be the perfect size for the Anker 737. It isn’t a custom-fit solution, so the power bank will have some room to slide around unless you pack the extra space with cables or a small SSD. However, at this price, it provides essential scratch protection and basic shock absorption. If you usually keep your power bank tucked inside a padded camera backpack (like a Peak Design Everyday Carry), you don’t necessarily need a military-grade hard shell. You just need something to keep the screen from rubbing against your lenses or camera body. The GLCON fulfills this role perfectly. Its zippers are surprisingly smooth for a budget option, though the internal padding is notably thinner than the Hermitshell or RLSOCO options.

RLSOCO Carrying Case View on Amazon View on B&H
RLSOCO is known for making cases for high-end drones and medical equipment, and that pedigree shows here. The case feels incredibly dense and well-constructed. The exterior has a sophisticated matte finish that doesn’t attract dust or lint, which is a common problem with cheaper EVA cases. What sets this apart is the precision of the mold; the Anker 737 sits inside with a “click-like” fit that ensures zero movement. The mesh storage area is also reinforced, so your cables won’t put pressure on the power bank’s screen when the case is closed. I’ve used this case while trekking through rugged terrain, and it has handled being tossed into gear bins without a scratch. It’s slightly bulkier than the others, but that’s the trade-off for the absolute best protection money can buy for this specific power bank.

LTGEM Hard Case View on Amazon View on B&H
The LTGEM is a fantastic alternative that balances weight and protection. It’s slightly lighter than the RLSOCO, making it a better choice for those counting every gram in their carry-on luggage. The interior features a soft, anti-static lining that I find very reassuring for long-term storage. One unique touch is the high-quality hand strap; it’s securely stitched and makes it much easier to pull the battery out of a deep bag. While it lacks the extreme rigidity of the Hermitshell, it offers more than enough protection for standard travel scenarios. I’ve noticed that this case also fits the Anker 737 alongside a small 20W “nano” charger if you position it correctly in the mesh pocket. It’s a reliable, well-reviewed option that won’t let you down on a long flight.

Frequently Asked Questions
Can I charge the Anker 737 while it is inside the case?
I strongly advise against this. The Anker 737 can output up to 140W, which generates significant heat. Charging or discharging at high speeds inside a closed EVA case can lead to thermal throttling or, in extreme cases, damage to the battery cells. Always remove the power bank from the case during use to allow for proper heat dissipation through its exterior casing.
Will these cases fit the wall charger as well?
Most of these cases, like the Hermitshell and RLSOCO, are designed specifically for the power bank and its cable. While you might fit a very slim Gallium Nitride (GaN) charger in the mesh pocket, a standard brick-style charger will likely be too bulky and could put dangerous pressure on the power bank’s screen when the case is zipped shut.
Is the Anker 737 airline safe in these cases?
Yes, the Anker 737 has a capacity of 86.4Wh, which is well under the 100Wh limit set by the FAA and most international airlines. Keeping it in a hard case is actually recommended by many flight crews, as it prevents the power buttons from being accidentally pressed and protects the battery from physical damage that could lead to safety issues.
Are these cases waterproof?
Most of the cases listed, including the Hermitshell and Khanka, are “water-resistant.” This means they can handle light rain or a spilled drink, but they are not submersible. The zippers are usually the weak point where water could seep in. If you are doing serious maritime photography, you might want to place the case inside a dry bag for total peace of mind.
How do I clean the interior lining?
Over time, the soft lining can collect dust or lint. I recommend using a simple lint roller or a piece of masking tape to lift debris. If you get a stain, use a slightly damp (not wet) microfiber cloth with a tiny drop of mild detergent. Ensure the case is completely dry before putting the battery back in, as moisture is the enemy of electronics.
Final Verdict
For the majority of users, the Hermitshell Hard Case provides the best custom fit and screen protection for the Anker 737. If you’re a professional photographer who is often in harsh environments, the RLSOCO offers a more premium, rugged build. However, if you simply want to keep your battery from getting scratched while sitting in your backpack, the Khanka or GLCON are excellent, cost-effective alternatives that get the job done without bulk.
