This article covers (ケースサック) CaseSack Verizon MiFi 6620L Jetpack 4G LTE モバイルホットスポット用保護ケース 充電器用スペース付き ケーブル — a case that solves how you carry a mobile hotspot, not the hotspot itself.
Overview
The CaseSack protective case for the Verizon MiFi 6620L Jetpack is a semi-rigid zippered case for people who want the router, its wall charger, and a cable to travel as one kit. It measures 5.9 x 3.85 x 1.95 inches (about 15.0 x 9.8 x 5.0 cm).
The nearly 2-inch depth is deliberate: the lid side holds the charger, which is why this is thicker than a slim sleeve.
This is a model-specific case, not a general gadget pouch. As captured on 2026-09-07, the listing showed 489 reviews at 4.6 out of 5 stars (92% positive).
For a case, that review volume matters — fit complaints are the usual source of one-star ratings, so a high score across hundreds of reviews is meaningful evidence that it actually fits the listed models.
Bottom line: if you own one of the supported hotspots and want your kit consolidated, this is an easy pick. If you want to store a different device, or need waterproofing or rated drop protection, look elsewhere.
Compatibility Guide
Officially supported models are the Verizon MiFi 6620L, 5510L, and 4620L Jetpack 4G LTE Mobile Hotspots. The case also fits the original wall charger and includes a mesh pocket for cables and USB drives.
| Item | Value | What it means in practice |
|---|---|---|
| Dimensions | 5.9 x 3.85 x 1.95 in (~15.0 x 9.8 x 5.0 cm) | Interior is several mm smaller; borderline devices won't fit |
| Compatible models | MiFi 6620L / 5510L / 4620L | Other brands depend entirely on measurements |
| Material | Semi-rigid plastic / nylon | Good against pressure and scuffs; not for water |
| Included | Case and removable wrist strap | Device, charger, and cables sold separately |
The most common mistake with cases like this is buying it for a device that isn't on the list because it "looks about the same size." A semi-rigid shell doesn't stretch the way fabric does, so being 5 mm too thick means the zipper simply won't close.
Measure your device and compare against the interior, not the exterior.
Also note the design targets North American Verizon hardware. Many hotspots sold elsewhere use wider, flatter bodies, so even if the volume matches, the internal layout may not.
For those, judge it as a generic pouch rather than a fitted case.
Product Info
As captured on 2026-09-07, the price was ¥4,210 on Amazon and $22.99 on eBay US.
Those are roughly consistent once currency is accounted for, so neither looks like a mis-scraped figure. Accessory pricing moves with stock levels, though, so check the product page for the current price before buying; sale pricing happens.
Construction combines a semi-rigid plastic shell with nylon and a full-perimeter zipper. It isn't as stiff as a molded EVA case, but it's rigid enough that a laptop or book pressing against it in a bag won't squeeze the router directly.
The package contains the case and a removable wrist strap only. Warranty terms should be confirmed with the manufacturer or the listing.
Compared to the Alternatives
There are three realistic options for this job:
- Generic gadget pouch — cheap and flexible, but the device slides around. The router ends up resting against the charger's corner and picks up scratches.
- Molded EVA hard case — maximum protection, but noticeably bigger and heavier for the same capacity. Overkill for a daily bag.
- This case (model-fitted, semi-rigid) — the middle ground. Nothing shifts inside, and the outer footprint stays compact.
The decision hinges entirely on whether your model is on the compatibility list. If it is, take the fitted case; if not, take a generic pouch.
Best Use Cases
- Daily commuters and students — keeps the router from rubbing against keys and pens, and the zipper closure blocks dust and lint.
- Frequent travelers — router, charger, and cable stay together, so you don't leave the charger behind at the last hotel. The wrist strap is removable for bag storage.
- Owners of multiple MiFi units — one case covers the 6620L, 5510L, and 4620L.
- Anyone storing a secondhand MiFi — older 4G LTE units lose their accessories easily; this keeps the set intact.
It's a poor fit for larger desktop routers, bulkier modern hotspots, or tablets. Buy a larger generic pouch for those.
Things to Check Before Buying
1. It's a fitted case, not a universal pouch. The listed size is the exterior; the usable interior is smaller.
A rigid shell has no give, so a few millimeters over means it won't close.
2. It is not waterproof. Plastic and nylon with a standard zipper — water gets in.
For outdoor or job-site use, pair it with a zip bag or buy a rated waterproof case. There is no published drop rating either.
3. The target devices are an older generation. The 6620L, 5510L, and 4620L are 4G LTE-era North American units.
Confirm exactly which device you own before buying a case sized for them.
4. Verify the listing yourself. Marketplace product data is partly auto-populated and can disagree with the physical item; this product appears through multiple channels and the seller and currency fields were not fully consistent across them.
Check the product photos and title to confirm you're looking at the right item, and treat the prices here as 2026-09-07 snapshots that may have changed.
5. Internal retention is minimal. There's a mesh pocket, but don't expect straps holding the router in place.
Put the charger on the lid side and the router on the base side so they don't press together in transit.
FAQ
Q. Will it fit hotspots other than the 6620L? A.
Only the 5510L and 4620L are listed. Anything else depends on measurements against the 5.9 x 3.85 x 1.95 inch exterior, minus wall thickness.
Q. Will a third-party charger fit? A.
It's sized for the original wall charger. Similarly sized USB chargers usually work, but high-wattage GaN bricks may be too thick.
Q. Is it waterproof?
A. No. No water resistance is claimed.
Q. What does it cost?
A. As of 2026-09-07, ¥4,210 on Amazon and $22.99 on eBay US. Check the listing for current pricing.
Q. Are the ratings trustworthy? A.
489 reviews at 4.6 out of 5 (92% positive) as of 2026-09-07 — enough volume to be a reasonable signal on fit.
Q. Can I carry cables and USB drives too? A.
Yes, in the mesh pocket. Capacity is limited, so a full kit including a power bank won't fit.
