Best Carrying Case for Anker 737 Power Bank
The Anker 737 (PowerCore 24K) is a beast of a power bank, but its glossy smart display is a total scratch magnet. I’ve seen far too many photographers toss this $150 unit into a gear bag only to have the screen scuffed by a stray charging cable or tripod plate. Protecting that 140W investment is essential for field work. I’ve tested several options, and the Khanka Hard Case currently stands out as the gold standard for fit and durability.

Best Carrying Case for Anker 737 Power Bank: Detailed Reviews
Khanka Hard Travel Case View on Amazon View on B&H
The Khanka Hard Travel Case is specifically engineered for the unique, brick-like dimensions of the Anker 737. Unlike “universal” pouches that let the heavy battery slide around, this case features a precision-molded interior that cradles the unit securely. I find the soft velvet lining particularly impressive; it prevents the PowerCore’s glossy screen from picking up micro-scratches during transit. The exterior is made of high-density EVA material, providing excellent shock resistance if you happen to drop your bag. There is a dedicated mesh pocket in the lid that perfectly fits the 140W USB-C cable that comes with the bank. While it adds a bit of bulk to the overall footprint, the peace of mind it provides when packing the 737 alongside heavy camera bodies is well worth the extra centimeter. The zipper is smooth and feels rugged enough for years of use.

Hermitshell Hard Case View on Amazon View on B&H
If you’re looking for maximum protection without the premium price tag, the Hermitshell Hard Case is the way to go. It offers a slightly more spacious interior than the Khanka, which I actually prefer when I need to carry both a USB-C to C cable and a Lightning cable for multiple devices. The shell is rigid and water-resistant, protecting the 737 from accidental spills in your backpack—a common hazard for outdoor photographers. You’ll notice the build quality is surprisingly high for the price, with a sturdy wrist strap that makes it easy to pull out of a stuffed bag. The only minor drawback is that the fit is a tiny bit looser than the Khanka, but the internal elastic strap does a great job of keeping the power bank from rattling. It’s a pragmatic, durable choice for anyone who prioritizes function over form.

RLSOCO Hard Case View on Amazon View on B&H
The RLSOCO Hard Case is the most affordable option that still provides legitimate “hard-shell” protection. While many budget cases use thin fabric, RLSOCO uses a decent grade of EVA that can withstand significant pressure. It’s a no-frills design, but you’ll appreciate the slim profile if you’re trying to save space in a laptop sleeve or a small daypack. The interior features a simple mesh divider which is effective, though the padding isn’t quite as plush as the Khanka. I noticed the zipper can be a bit stiff during the first few uses, but it breaks in quickly. For the price of a couple of lattes, this case ensures you won’t have to deal with a cracked screen or dented corners on your Anker bank. It’s an honest, effective solution for users who want basic security without spending a fortune.

Peak Design Tech Pouch View on Amazon View on B&H
For those who carry more than just a power bank, the Peak Design Tech Pouch is the ultimate premium solution. While not specifically molded for the 737, the origami-style pockets allow the battery to sit upright and secure in the center compartment. I love this setup because I can keep my Anker 737, several SD cards, a wall charger, and all my cables in one weatherproof, aesthetically pleasing pouch. The 200D recycled nylon shell is incredibly durable and looks professional in any environment. You’ll find the cable pass-through feature particularly useful for charging your phone while the battery stays tucked inside the pouch. It’s significantly more expensive than a dedicated hard case, but for a photographer who values organization and style, it’s a game-changer that replaces three or four smaller bags. The lifetime warranty from Peak Design is the cherry on top.

LTGEM Hard Case View on Amazon View on B&H
The LTGEM Hard Case is a fantastic alternative to the Khanka, offering a slightly different aesthetic with its grey fabric-like texture. It is just as rigid and offers a snug fit that prevents any internal movement. In my experience, the LTGEM cases tend to have slightly better zippers that resist snagging even when the case is stuffed. It includes a mesh pocket for your 140W cable and a small carabiner loop, which is handy if you want to clip it to the outside of a bag temporarily (though I’d always recommend keeping the heavy 737 inside). The internal dimpled padding provides an extra layer of shock absorption that feels very premium. It’s a rock-solid choice for anyone who prefers a textured finish over the standard smooth EVA look. It handles the weight of the 737 effortlessly without deforming over time.

Frequently Asked Questions
Can I charge my devices while the Anker 737 is inside the case?
I strongly advise against this. The Anker 737 generates significant heat when outputting 140W, especially when charging a laptop. Keeping it zipped inside an EVA case traps that heat, which can lead to thermal throttling or, worse, internal battery degradation. Always remove the power bank from its case during use to ensure proper airflow and to keep the smart display from overheating. Safety first!
Will these cases fit the newer Anker Prime 27,650mAh model?
While the dimensions are similar, the Anker Prime series has a slightly different footprint. Most cases designed for the 737 will fit the newer Prime models, but they might be a bit snug or have a tiny bit of extra room. If you own the Prime model, look for cases that specifically mention “250W” or the newer model numbers to ensure the most secure fit possible for your device.
Is a hard case necessary for air travel?
Absolutely. TSA requires lithium-ion batteries to be in carry-on luggage, where they are often subjected to being squashed in overhead bins. A hard case protects the 737 from “crush” damage, which is a fire hazard. Plus, it keeps your cables organized so you aren’t fumbling at security. I never fly without my 737 tucked safely into a rigid EVA case for this exact reason.
Do these cases come with a charging cable?
Generally, no. These are third-party carrying cases and do not include the Anker 140W cable or a wall brick. However, most have a mesh pocket specifically designed to hold the cable that originally came with your Anker 737. If you’ve lost your original cable, make sure to buy a certified USB-C PD 3.1 cable to take full advantage of the power bank’s high-speed charging capabilities.
What is the best way to clean the interior of the case?
Over time, the velvet or mesh interior can trap dust or lint which can scratch the 737’s screen. I recommend using a simple lint roller or a quick blast of compressed air to clear out debris. If there’s a spill, a damp cloth with mild soap works for the exterior, but keep the interior as dry as possible to prevent mold or odors from developing in the padding.
Final Verdict
For most users, the Khanka Hard Travel Case is the clear winner due to its tailored design that prevents the heavy 737 from shifting. If you are a digital nomad or photographer with a complex kit, the Peak Design Tech Pouch is a worthwhile investment for overall organization. However, even the budget-friendly RLSOCO will vastly extend the life of your power bank by protecting that vulnerable smart display from the rigors of travel.
