Best Protective Case for Anker 737 Power Bank
The Anker 737 (PowerCore 24K) is an absolute beast for field photographers, but its glossy smart display is a magnet for scratches and cracks. After hauling mine through rugged shoots from the Dolomites to local weddings, I’ve learned that a dedicated hard shell is non-negotiable for protecting that 140W investment. In this guide, I’ll share the best protective cases that offer a glove-like fit, ensuring your power bank survives the chaos of a packed gear bag.

Best Protective 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. Having used their cases for my wireless mic systems, I knew the build quality would be tactile and tough. This specific model is laser-cut to the 737’s unique “coke-can” dimensions (roughly 6.1 x 2.1 x 1.9 inches), ensuring the power bank doesn’t rattle during transport. The exterior is a heavy-duty EVA that shrugs off compressions in a stuffed Shimoda bag, while the internal mesh pocket is just deep enough to hold the 140W USB-C cable without pressing against the screen. I particularly appreciate the heavy-duty zipper; it feels substantial and hasn’t snagged once. While it adds a bit of bulk to the power bank’s footprint, the peace of mind when throwing a $150 charger into a bin of metal camera supports is well worth the extra few millimeters of thickness.

Khanka Hard Travel Case View on Amazon
The Anker 737’s smart display is surprisingly delicate, and the Khanka Hard Travel Case addresses this better than most. While the exterior is a standard water-resistant fabric-covered EVA, the interior is lined with an incredibly soft velvet-like material. I find this essential because even small particles of grit in a gear bag can micro-scratch that screen. The Khanka offers a snug fit that prevents the device from sliding, which is a common flaw in generic “small electronics” cases. The value proposition here is unbeatable; you’re getting pro-level shock absorption for the price of a couple of coffees. My only minor gripe is that the hand strap feels a bit flimsy compared to the Hermitshell, but since most photographers will just tuck this inside a larger pack, it’s rarely a dealbreaker for the daily carry.

JSVER Hard Shell Carrying Case View on Amazon
If you’re looking for the absolute most affordable way to keep your Anker 737 from getting beat up, the JSVER Hard Shell is the way to go. It foregoes some of the thicker padding found in premium options to maintain a slimmer profile, which I actually prefer when I’m using a smaller 15L “commuter” style camera bag. The case is rigid enough to protect against accidental drops on the pavement, though the interior doesn’t have the same high-end plushness as the Khanka. It fits the 737 perfectly lengthwise, though there is a tiny bit of wiggle room on the sides that you might notice if you don’t have the cable stored in the mesh pocket to take up the space. For a budget pick, the zippers are surprisingly smooth, making it a reliable choice for photographers who prioritize cost and weight over maximum ruggedness.

RLSOCO Carrying Case for Anker 737 View on Amazon
RLSOCO is known for making precision cases for drones and high-end tech, and their Anker 737 case feels noticeably more “pro” than the generic options. The exterior material has a refined, matte texture that doesn’t pick up dust or lint—a common annoyance with cheaper fabric cases. Inside, the foam molding is exceptionally dense, offering the best impact protection in this lineup. I find this particularly useful for air travel where carry-on bags are frequently shoved into overhead bins. The internal space is efficiently used, with a secure strap that holds the power bank firmly in place even if the case is dropped while open. It’s slightly more expensive than the Hermitshell, but the aesthetic and the extra-thick shell walls make it the superior choice for professionals carrying high-end mirrorless kits.

Aenllosi Hard Storage Case View on Amazon
When you’re managing a bag full of black cables and black camera bodies, the Aenllosi Hard Storage Case is a lifesaver because it’s often available in different internal colors or stitching. I’ve used Aenllosi cases for my portable SSDs for years, and they hold up remarkably well to friction. This case fits the Anker 737 like a second skin. The internal mesh is tight, which is actually a benefit as it keeps your USB-C to USB-C 140W cable from falling out whenever you unzip the case. The shell is rigid enough to withstand someone accidentally stepping on your bag, and the zipper pulls are oversized, making them easy to operate even if you’re wearing gloves during a cold sunrise shoot. It’s a solid, dependable alternative if our top pick is out of stock.

Frequently Asked Questions
Will these cases fit the wall charger as well?
Generally, no. These cases are precision-molded specifically for the Anker 737 unit and a charging cable. The Anker 140W wall charger is quite bulky on its own. If you need to carry both, you would likely need a larger, universal electronics organizer rather than a fitted hard shell. For most photographers, keeping the power bank in a fitted case and the wall charger in a separate tech pouch is the most space-efficient method.
Is the Anker 737 case waterproof?
Most of the cases listed, like the Hermitshell and RLSOCO, are water-resistant. This means they can handle a light splash or being set down on a damp surface, but they are not submersible. The zippers are usually the weak point for water entry. If you are doing heavy maritime or rainforest photography, I recommend placing the hard case inside a dry bag for absolute protection against the elements.
Do I really need a case for a power bank?
For the Anker 737, absolutely. Unlike older, ruggedized power banks, the 737 features a sophisticated LED smart display that shows real-time wattage and battery health. This screen is prone to cracking under pressure or scratching from other gear in your bag. A $15 case is a very small price to pay to protect a high-end device that costs over $130 and is central to your mobile power workflow.
Will the case cause the power bank to overheat?
You should never charge the power bank or use it to charge other devices while it is inside the closed case. Heat dissipation is critical for GaN chargers, especially when outputting at 140W. These cases are strictly for storage and transport. Once you’re at your location and ready to charge your camera or laptop, remove the 737 from the case to ensure it stays cool and operates at peak efficiency.
Which case is the lightest for hiking?
The JSVER Hard Shell is typically the lightest option because it uses a slightly thinner EVA shell and a more streamlined design. If you are counting every ounce for a multi-day backpacking trek but still want to protect that 24,000mAh capacity for your camera batteries, the JSVER provides the best protection-to-weight ratio. It offers just enough rigidity to prevent impact damage without adding unnecessary bulk to your pack.
Final Verdict
If you want the absolute best protection for your Anker 737, the Hermitshell is the professional’s choice for its rigid build and perfect dimensions. For those who are particularly worried about the smart display’s finish, the Khanka’s plush lining is a fantastic alternative. Budget-conscious travelers or hikers should lean toward the JSVER for its slim profile. Regardless of which you choose, putting your 737 in a case is the best way to ensure your field power remains reliable for years.
