Amazon Basics 128GB microSDXC Memory Card with Adapter for Smartphones, Drones, Cameras, Full HD
Quick take
This 128GB microSDXC card from Amazon Basics is built for everyday expansion and media recording in phones, cameras, tablets, and dash cams. It targets speed-conscious use with up to 200MB/s read performance and UHS-I/U3, Class 10, and A2 support, but the highest advertised read speeds require a compatible card reader.

- Ruggedness features include shockproof, IPX6 waterproof, temperature-proof (-10° to 80°), X-ray-proof, and magnetic-proof.

What buyers think
Buyer feedback is broadly positive and focused on value and practical day-to-day performance. Reviews commonly describe the card as working reliably in cameras, dash cams, and other storage-expansion setups, and mention it as a cost-effective option compared to local retail pricing. There is also some limited feedback around the included items, specifically that a USB-C card reader is not included even though it can be shown in product images. Overall, review evidence points to a “works as expected” experience, with the most notable expectation-management items being speed requirements and included accessories.
What this card is best for
The Amazon Basics 128GB microSDXC card is a good fit when you want more storage and consistent performance across common media devices. The combination of 128GB capacity and speed classes (UHS-I, U3, Class 10, and A2) suggests it is aimed at recording and storing high-resolution video, plus faster app and media loading on compatible devices.
- Phones and tablets: Useful for expanding internal storage, storing high-res photos, and keeping more content offline.
- Cameras and action cameras: A straightforward option for capturing Full HD through higher-resolution video workflows.
- Dash cams and security devices: A practical capacity and reliability-oriented design for ongoing recording.
- Consoles, laptops, and other devices: Works in systems that accept microSDXC up to 128GB (and that support the needed speed profile).
Key specs that matter in real use
Capacity and storage recognition
With 128GB labeled capacity, real usable space can be lower depending on operating system measurement methods. The card is also compatible with devices that support microSDXC capacity up to 128GB, so it is worth checking whether your device has a maximum supported microSD size.
Speed ratings, and why your reader matters
The card is rated for reads up to 200MB/s and writes up to 150MB/s. It also supports speed classes intended for smoother performance, including UHS-I, U3, Class 10, and A2. However, the top read figure requires using a compatible microSD card reader, since the card reader you use can be the limiting factor.
Rugged design for outdoors and rough handling
Amazon Basics includes ruggedness features that appeal to outdoor and travel use. The card is described as shockproof and IPX6 waterproof, with temperature tolerance (-10° to 80°), plus X-ray-proof and magnetic-proof protection. If your use case involves taking the card into harsher environments, this spec set is a relevant reason to choose it.
Pros and cons, simplified
Why it’s a strong pick: The standout combination is a sensible 128GB capacity, speed class support aimed at recording and faster app behavior (A2), and ruggedness features. Buyers also seem to appreciate it as a cost-effective storage expansion card that works well across common devices.
What to watch before buying: Make sure you have the right reader if you care about hitting the maximum advertised read speeds, and confirm your device supports microSDXC up to 128GB. Also note that it is not compatible with Nintendo Switch 2.
Who should buy
- You want a 128GB microSDXC card for cameras, dash cams, phones, or tablets.
- Your workflow benefits from UHS-I/U3 and A2 support (where your device supports it).
- You want added protection for outdoor or rougher environments (IPX6, temperature-proof, shockproof).
- You prefer a bundle that includes a microSD-to-SD adapter.
Who should avoid
- You need microSD support for Nintendo Switch 2 (this card is not compatible).
- You must guarantee maximum advertised speed regardless of setup, since the top read performance depends on the card reader and device interface.
- Your device supports only smaller microSD capacities, since it may not recognize the full 128GB capacity.

At the time of review, this card is listed as in stock in the United States. Pricing can change, so the best way to confirm your current deal is to check the latest listing details.
Final verdict
The Amazon Basics 128GB microSDXC card is a practical, feature-rich storage upgrade for most mainstream devices that accept microSDXC up to 128GB. Its speed class support and rugged spec set make it especially appealing for recording and outdoor use. Just plan around the key caveat: to get the very highest read speeds, you will need a compatible card reader, and your device must support the needed microSD capacity and profiles.
FAQ
What devices is this microSD card compatible with?
It is designed for microSDXC-capable devices such as smartphones, tablets, cameras, action cameras, laptops/desktops, DSLRs, drones, and gaming consoles. It is not compatible with Nintendo Switch 2. If your device has a lower maximum microSD capacity limit, it may not recognize the full 128GB.
Does it include a card reader?
No. The card includes a microSD-to-SD adapter, but the USB-C 3.0 microSD card reader needed to reach the top advertised read speed is sold separately.
What speed can I realistically expect?
The card is rated up to 200MB/s read and up to 150MB/s write, but real-world performance depends on the device, interface, conditions, and especially the card reader you use. For best results, use hardware that supports the same speed class expectations.
Will my device show the full 128GB?
Not always. Storage shown by operating systems can be less than the labeled capacity due to different measurement standards. The card is expected to provide available storage capacity higher than 116GB, but the exact amount depends on your device.
Is this microSD card durable?
It is described as shockproof and IPX6 waterproof, and it is temperature-proof (-10° to 80°), X-ray-proof, and magnetic-proof, which makes it a better match for outdoor and active use.
