Everyone owns a power bank, and almost everyone treats it badly. A power bank slides into a bag, rattles against keys, takes a drop from a pocket, and comes out scratched or dented. The YWXTW silicone case exists to stop that cycle for the Anker 20,000mAh 87W power bank, model A1383, with a shock absorbing shell, a lanyard, and an open window for the LCD display. I carried mine every day for three weeks, dropped it on purpose, and shoved it through crowded commutes to see whether a sleeve really earns its place.

A quick disclosure note. This review contains affiliate links, and purchases through them support this site at no extra cost to you. That never changes my verdict, and all opinions here come from my own use of the case.

Design and Build

The case is molded specifically for the Anker A1383, and the fit shows it. The grey silicone hugs every curve of the power bank with no slack and no bulging, and the corners are reinforced with a slightly thicker bumper that absorbs the first impact. The open window over the LCD display sits exactly where the Battery percentage shows, and the lanyard loops through slots at the top with a clip that feels sturdy enough for real daily use.

Build quality is exactly what a protective accessory should be. The silicone is soft enough to grip well but firm enough to keep its shape, and it does not attract dust or lint the way cheaper sleeves do. The cutouts line up precisely with every port, button, and the USB-C opening, so the case never gets in the way of charging. For the price, the construction is genuinely impressive.

Key Features

Impact protection is the case's main job, and it does it well. The silicone layer sits between the power bank and the world, cushioning drops and spreading the force of an impact across the shell. The drop resistant claim held up in my testing, and the reinforced corners are the first line of defense for the most vulnerable edges.

The lanyard adds a genuine usability upgrade. It clips securely to the case, letting you hang the power bank from a backpack strap, a bag handle, or a shoulder, which keeps a heavy 20,000mAh bank off your hands when you are moving. The strap does not flap or catch during a walk, and it stays firmly attached under a full load.

The display window and port access round out the design. The LCD cutout means you can read the remaining percentage at a glance without removing the case, and every port stays fully open, so the bank charges and charges your phone exactly as it would without the cover. The protective focus of the design never sacrifices function.

Real-World Performance

I carried the case for three weeks through crowded commutes, gym bags, and travel, and the power bank came through spotless. The silicone took scuffs that would have marked the bare metal, and a deliberate drop from waist height onto tile left the bank with no damage and the case with only a minor mark. The grip also makes the bank easier to hold, which is a real benefit for a device that is already dense and boxy.

The lanyard became my favorite detail. Hanging the bank from a backpack strap kept it within reach while charging a phone on the move, and the clip never slipped during any of my walks. The display window worked as promised, giving me the battery percentage without ever peeling back the cover.

The honest limitation is that this is a protection accessory, not a fix for the power bank's own size. A 20,000mAh bank is heavy regardless of the sleeve, and the case adds a little bulk on top. For anyone who has already accepted that weight, the case makes the device easier to grip, carry, and protect, which is exactly what a sleeve should do.

The grip improvement is easy to underestimate until you hold the bare bank again. Bare metal at this size is slippery and prone to sliding off a desk or out of a hand, while the silicone texture gives a confident purchase that feels secure even one handed. I noticed the difference most when pulling the bank out of a crowded bag, where the soft outer layer also stopped it from scratching against a phone screen or a laptop corner. Small protection details like that compound over the life of a device.

I should also note the way the case behaves with cables. The port cutouts are generous, so both USB-C and the bank's output ports accept thick braided cables without forcing the plug, and the cutouts keep the cables aligned while the bank charges. The case does not add height around the ports, which means the bank still sits flat on a surface while charging, and there was no wobble even with a cable attached. That attention to everyday use is what separates a well designed accessory from a generic cover.

Pros and Cons

Pros:

  • Precise fit for the Anker A1383 power bank
  • Reinforced corners absorb real drops
  • LCD display stays fully visible through the window
  • Sturdy lanyard adds a carry option
  • All ports and buttons remain fully accessible
  • Soft silicone adds grip and feels premium

Cons:

  • Adds a little bulk to an already heavy bank
  • Only fits the A1383, not other Anker models
  • Grey finish shows light scuffs over heavy use
  • No included belt loop for the lanyard

How It Compares

Set against a generic neoprene pouch, the YWXTW case wins on fit, access, and drop protection. A pouch holds any power bank, but you must open it to read the display or plug in a cable, and it offers no shock absorption. Against a hard shell case, the silicone version absorbs impacts better while staying slim and flexible. The comparison below keeps it straightforward.

Feature YWXTW Silicone Case Generic Pouch Hard Shell Case
Fit Precise for A1383 Loose for most Model specific
Impact protection Reinforced corners Minimal Good
Display access Always visible Open to use Usually covered
Port access Fully open Open to use Cutouts
Carry option Lanyard included Often none Often none
Price Very affordable Lowest Moderate

The verdict is that this case does everything a protective sleeve should, and it does it better than the alternatives because it is built for one specific power bank. If you own an Anker A1383, there is no reason to settle for a bag that hides the display and adds no protection.

Who Should Buy It

This case suits anyone who carries an Anker 20,000mAh 87W power bank daily and has watched it get scratched, dented, or dropped. It is ideal for commuters, travelers, and students who toss a heavy bank into a bag with keys and Chargers, and the lanyard makes it a genuinely handy carry for anyone who wants the bank within reach.

Skip it if your power bank is a different model or if you would rather protect the bank inside an existing bag pocket. If the fit is right for your A1383, you can check the current price of this case on Amazon.

How We Test

I used the case on my own Anker A1383 for three weeks of daily commuting, gym trips, and travel, and I verified the fit against the exact ports, buttons, and display window. I dropped the protected power bank deliberately from waist height onto tile and concrete to test the impact protection, hung it from a backpack strap to confirm the lanyard, and checked the display readability and charging access repeatedly with the cover in place.

A closing word on whether the case is worth buying at all. A power bank is one of the most abused accessories people own, because it is heavy, travels constantly, and sits unprotected in a bag. A scratch on a phone screen or a dented corner on the bank is a common consequence, and both are exactly what this sleeve prevents. For the price of a coffee, the case extends the life of a device that cost a good deal more, and in my three weeks of hard use it never once felt like an unnecessary purchase.

Yes. It is molded specifically for the Anker A1383, the 20,000mAh 87W model, and the fit is snug with every port, button, and the LCD display left fully accessible.

Does the case cover the LCD display?

No. A window is cut out over the display, so the battery percentage stays readable at all times without removing the cover, which I confirmed on every charge during testing.

Is the silicone case really drop resistant?

Yes. The silicone cushions impacts and the reinforced corners protect the edges, and my deliberate drops onto tile and concrete left the power bank unharmed.

How does the lanyard attach?

A sturdy strap loops through the case and clips securely at the top, so you can hang the power bank from a backpack strap or carry it by hand without the case pulling away.
