Best Carrying Case for Anker 737 Power Bank
The Anker 737 Power Bank (PowerCore 24K) is a portable powerhouse for photographers, but its bulky “coke-can” shape and fragile digital display make it a liability in a cramped gear bag. I’ve seen too many pristine screens ruined by stray tripod plates. To keep your 140W beast safe, you need a dedicated hard-shell case. After testing several options during field shoots, I’ve found the Hermitshell Hard Travel Case offers the best balance of ruggedness and tailored fit.

Best Carrying Case for Anker 737 Power Bank: Detailed Reviews
Hermitshell Hard Travel Case View on Amazon
The Hermitshell Hard Travel Case is the gold standard for the Anker 737. When you’re tossing gear into a backpack for a sunrise landscape shoot, you need something that can handle compression. This case is built from heavy-duty EVA that doesn’t flex under pressure, ensuring that the 737’s sensitive smart display remains unscathed. I particularly like the internal mesh pocket; it’s deep enough to hold the chunky 140W USB-C cable without pressing against the battery body. The fit is snug enough to prevent rattling but loose enough that you aren’t fighting to get the power bank out. The zipper is remarkably smooth for a case at this price point, and the included carabiner is a nice touch for hanging it off a tripod or bag strap. While it adds a bit of bulk, the peace of mind it provides for a $150 power bank is well worth the extra centimeter.

Khanka Hard Case View on Amazon
If you want top-tier protection without spending a dime more than necessary, the Khanka Hard Case is your best bet. It mimics the design of more expensive cases but manages to keep the cost down. The standout feature here is the interior lining; it’s a soft, velvet-like material that prevents micro-scratches on the Anker 737’s glossy faceplate. In my testing, the Khanka felt slightly lighter than the Hermitshell, which is a plus if you’re already carrying heavy mirrorless bodies. The exterior is splash-resistant, though I wouldn’t trust it in a downpour. It fits the 737 like a glove, and the elastic strap keeps the battery from sliding around when the case is half-open. The only minor drawback is that the mesh pocket is a bit tight; if you’re trying to fit a wall charger in addition to the cable, it might be a squeeze. However, for sheer value, it’s hard to beat.

Aenllosi Hard Carrying Case View on Amazon
The Aenllosi Hard Carrying Case is the most compact option on this list. For those of us who use small sling bags like the Peak Design 6L, every millimeter of space counts. The Aenllosi has thinner walls than the Hermitshell, which makes it slightly less crush-proof but significantly more pocketable. Don’t let the “budget” label fool you; the build quality is solid, and the fabric exterior has a nice grip to it. It lacks a dedicated internal strap, so the battery can shift slightly, but the interior dimensions are so tight that it doesn’t have much room to move anyway. It’s an honest, no-frills case that does exactly what it says on the tin: protects the Anker 737 from scratches and minor drops. If you aren’t planning on dropping your bag off a cliff, this is all the protection you really need for a very low price.

Think Tank Photo Cable Management 10 V2.0 View on Amazon
For professionals who live and die by their cable management, the Think Tank Photo Cable Management 10 is a superb alternative to a hard case. While it’s a soft-sided pouch, the padding is thick and the materials are world-class. I love the clear TPU window; it allows you to see if you’ve actually packed the 737 without opening the bag. It’s large enough to hold the Anker 737, several long USB-C cables, and even a small wall charger like the Anker 735. The YKK zippers are the best in the business and won’t fail even after years of use. While it doesn’t offer the crush-proof protection of an EVA shell, it integrates much better into a professional camera bag workflow. If you organize your gear by “kits,” this is the premium way to house your power station and all associated peripherals in one sleek, durable package.

Peak Design Tech Pouch View on Amazon
The Peak Design Tech Pouch is over-engineered in the best possible way. If you don’t want a dedicated case just for your power bank, this is the “one bag to rule them all.” The Anker 737 fits perfectly in the central compartment, while the origami-style internal pockets can house your SD cards, batteries, and dongles. The 200D recycled nylon shell is weather-resistant and incredibly durable. I find the cable pass-through feature particularly useful; you can keep the 737 inside the pouch while charging your phone externally. It’s bulky, yes, but it replaces three or four smaller pouches. The only downside is the price—it’s an investment. But if you already own Peak Design bags, the mounting points on the back allow it to clip directly into their ecosystem, making it a dream for organized travel.

Frequently Asked Questions
Will these cases fit the wall charger as well?
Most dedicated hard cases like the Hermitshell or Khanka are designed primarily for the power bank and its cable. While you might be able to squeeze a slim 30W charger inside, a full-sized 140W GaN charger will usually be too thick for the mesh pocket. For carrying both the battery and the brick, the Think Tank or Peak Design options are much better suited due to their expandable nature.
Is the official Anker pouch that comes in the box enough?
Honestly, no. The drawstring pouch Anker includes is fine for preventing dust, but it offers zero impact protection. Because the 737 is so heavy, even a short drop inside that pouch can lead to a cracked screen or internal damage. If you’re traveling or packing it with other metal gear, a hard shell is a mandatory upgrade to protect your investment.
Are these cases water-resistant for outdoor photography?
The EVA cases (Hermitshell, Khanka) are splash-resistant thanks to their synthetic outer fabric, meaning they’ll survive a light drizzle or a spill in your bag. However, they are not waterproof. The zippers are the weak point where water can seep in. If you need 100% waterproof protection, you would need to step up to a small Pelican-style hard case with an O-ring seal.
Does the 737 overheat if kept inside the case while charging?
You should never charge devices with the 737 while it is zipped inside a hard case. The Anker 737 generates significant heat when outputting 140W, and hard cases act as insulators. Always remove the power bank from the case during use to allow for proper airflow. The Peak Design Tech Pouch is slightly better for this due to its breathable fabric, but it’s still best practice to keep it out.
Can I use these cases for the older Anker 737 (PowerCore III Elite)?
No. The older Anker 737 is a flat, wide power bank, whereas the newer 737 (PowerCore 24K) is a tall, thick brick. Cases designed for one will not fit the other. Always check that the case specifically mentions “PowerCore 24K” or “GaNPrime” to ensure the dimensions match the newer, more popular 140W model featured in this guide.
Final Verdict
If you want the absolute best protection, the Hermitshell is a no-brainer—it’s the most rugged shell I’ve tested for this specific power bank. For the budget-conscious, the Khanka offers nearly identical performance for a few dollars less. If you’re a professional photographer who needs to organize cables alongside the battery, skip the hard shells and invest in the Think Tank Management 10. Regardless of your choice, getting your 737 out of that flimsy factory bag and into a real case is the best thing you can do for your gear’s longevity.
