Best Travel Case for Anker 737 Charger
The Anker 737 Power Bank (PowerCore 24K) is a beast of a charger, but its glossy smart display and heavy chassis are magnets for scratches and impact damage. As a traveling photographer, I’ve seen how quickly gear gets battered in a crowded bag. You need a dedicated hard shell to protect that 140W investment. While many generic pouches exist, the RLSOCO Carrying Case stands out for its precision-molded interior that stops this heavy “brick” from shifting during transit.

Best Travel Case for Anker 737 Charger: Detailed Reviews
RLSOCO Carrying Case View on Amazon View on B&H
The RLSOCO case is the gold standard for the Anker 737. Most cases are just rectangular boxes, but this one features a precision-cut EVA foam slot that mirrors the 737’s unique “coke can” dimensions. This is vital because the 737 weighs a hefty 1.4 lbs; in a generic case, it acts like a hammer, bashing against the sides during movement. The interior is lined with soft green fabric that prevents micro-abrasions on the charger’s screen. I particularly appreciate the sturdy mesh pocket in the lid, which is actually deep enough to hold a 140W USB-C cable and a small wall plug without putting pressure on the power bank. The exterior is a high-density polyester that feels professional and rugged. The only downside is it’s slightly bulkier than a sleeve, but for a $150 charger, that’s a trade-off I’ll take every day.

Hermitshell Hard Travel Case View on Amazon View on B&H
If you don’t need the custom foam molding of the RLSOCO, the Hermitshell is a fantastic value proposition. It provides a semi-rigid exterior that protects against drops and spills, and it’s specifically sized for the PowerCore 24K. I find the zipper on Hermitshell cases to be surprisingly smooth for the price point, and it comes with a handy carabiner if you want to clip it to the outside of a hiking pack—though I’d recommend keeping such a heavy battery inside your bag for better weight distribution. The interior is a simple velvet-style lining with an elastic strap to keep the charger from sliding. While it doesn’t feel as “bespoke” as the premium options, it does its job perfectly. It’s a no-nonsense case for someone who wants protection without the “tech-gear” price premium. Just be careful not to overstuff the mesh pocket, as it sits directly against the charger’s screen.

Khanka Hard Travel Case View on Amazon View on B&H
The Khanka case is for the traveler who counts every cubic centimeter in their carry-on. It has the slimmest profile of the bunch, hugging the Anker 737 closely. Despite the low price, the build quality is honest. It uses a classic hard EVA shell covered in a scratch-resistant fabric. I’ve found Khanka cases to be incredibly resilient to being crushed at the bottom of a suitcase. The trade-off for its slimness is storage; you can fit the essential USB-C cable, but don’t expect to jam a wall brick in here. The internal elastic band is quite tight, which I actually prefer, as it ensures the battery doesn’t shift even a millimeter. It lacks the premium padding of the RLSOCO, but it’s a massive step up from the mesh bag Anker provides in the box. If you just want to stop your keys from scratching the 737 screen, this is the one.

Co2CREA Hard Case (Double) View on Amazon View on B&H
For those who treat their Anker 737 as a mobile workstation hub, the Co2CREA case is the professional pick. Unlike the others that focus solely on the power bank, this case is slightly larger to accommodate the Anker 737 and a large 140W GaN wall charger simultaneously. If you’re a digital nomad, you know the frustration of having your battery in one pouch and your wall plug rattling around somewhere else. The internal divider is thick and soft, ensuring the two devices never touch. The shock-absorption is excellent, with a dimpled “bubble” lining that provides an extra air cushion. It’s definitely the largest case on this list, so it might not fit in a small sling bag, but it’s perfect for a dedicated tech organizer within a larger camera backpack. It feels high-end, with a heavy-duty handle and a water-resistant zipper seal.

LTGEM Hard Case View on Amazon View on B&H
LTGEM has a cult following for a reason: their cases are incredibly consistent. This model for the Anker 737 features a very rigid outer shell that resists compression even under heavy loads. If you tend to overstuff your luggage, this is a great choice because it won’t flex inward against the 737’s LCD screen. The interior is lined with a signature grey soft-fleece material that feels great and keeps the charger looking like new. I like the wrist strap on this model; it makes it easy to pull out of a deep bag. While it lacks the custom foam cutouts of the RLSOCO, the fit is snug enough that there is very little internal movement. It’s a solid middle-ground option that balances size, protection, and price. You can’t go wrong with it, especially if you already use LTGEM cases for your other peripherals and want a matching set.

Frequently Asked Questions
Will these cases fit the wall charger too?
Most standard cases like the RLSOCO or Khanka are designed only for the Anker 737 battery and a USB-C cable. If you need to carry the large 140W wall brick that often accompanies this power bank, you should specifically look for “Double Compartment” cases like the Co2CREA. Always check the internal height of the lid pocket before assuming a wall plug will fit without crushing the battery’s screen.
Are these cases waterproof?
Most are “water-resistant” but not fully waterproof. They are made of EVA and nylon/polyester which can handle a light splash or rain, but the zippers are usually the weak point. If you are frequently in wet environments, look for a case with a rubberized “aquaguard” zipper. For total immersion protection, you would need a hard-shell Pelican-style dry box, which is significantly bulkier than these options.
Can I use the power bank while it’s inside the case?
I strongly advise against this. The Anker 737 can generate significant heat when charging at its maximum 140W output. Hard EVA cases act as insulators and trap that heat, which can lead to thermal throttling or reduced battery lifespan. Always take the power bank out of the case during use to allow for proper ventilation, especially when charging high-drain devices like a MacBook Pro or a mirrorless camera.
Is the Anker 737 TSA approved for flights?
Yes, the Anker 737 has a capacity of 24,000mAh (approx. 86.4Wh), which is under the 100Wh limit set by the TSA and most international aviation authorities. However, it must be kept in your carry-on luggage—never in checked bags. Having a dedicated travel case makes it much easier to pull out during security screenings and protects it from the rigors of being shoved under an airplane seat.
Do these cases fit other Anker power banks?
These cases are specifically tailored for the “tower” shape of the Anker 737 (PowerCore 24K). They will not fit the flatter, wider Anker 747 or the smaller Anker 533 properly. If you have a different model, the battery will likely rattle around, defeating the purpose of a protective case. Always match the case to the specific model number of your charger to ensure a secure fit.
Final Verdict
For the vast majority of users, the RLSOCO case is the clear winner because it treats the Anker 737 like the premium piece of equipment it is. If you’re a professional who needs to keep your wall charger and cables in one unified kit, go for the Co2CREA. Minimalists who want to keep their bag light and slim should stick with the Khanka. Regardless of your choice, getting this battery out of a loose bag and into a hard shell is a smart move.
