You're standing in the middle of the electronics aisle at Walmart. It’s bright. It’s loud. You just realized your new phone doesn't fit your old car charger, and now you’re staring at a wall of plastic-wrapped cables that all look exactly the same. Honestly, buying a usb to usb c walmart adapter or cable should be simple, but it’s surprisingly easy to walk out with the wrong thing.
Most people think a cable is just a cable. It isn't.
If you grab the first $5 "Onn" brand cord you see, you might find that your phone takes six hours to charge instead of one. Or worse, it won't sync your data at all. This happens because the transition from the old USB-A (the rectangular one we've used since the 90s) to USB-C is a mess of different standards, speeds, and power ratings. Walmart carries everything from high-end Belkin products to budget-bin cables that barely meet safety standards. You have to know what to look for before you hit the checkout.
Why Your USB to USB C Walmart Choice Actually Matters
Cheap cables are a gamble. I’ve seen budget USB-A to USB-C adapters literally melt because they couldn’t handle the voltage pull of a modern laptop. It’s not just about the plastic housing; it’s about the internal resistors. Specifically, a proper USB-C to USB-A cable must have a 56kΩ resistor. This little component tells your device not to pull more power than the older USB-A port can provide. Without it? You risk frying your motherboard or your battery.
Walmart’s house brand, Onn, has actually improved quite a bit over the last two years. Their "Premium" line is generally solid for basic charging. However, if you're looking for something like the Belkin BoostCharge or an Anker cable (which Walmart now stocks in many locations), you're paying for better shielding and more durable connectors.

Think about how you use your phone. Do you yank the cord out by the wire? Do you use it while it's plugged in, bending the neck of the cable back and forth? If so, the $4.88 white cable at the bottom of the bin is going to fail in three weeks. It’s a waste of money. Spend the extra five bucks for the braided nylon version. Your wallet—and the environment—will thank you.
Understanding the Different Types of Adapters
When you search for usb to usb c walmart, you'll see two main categories: cables and "dongles" (adapters).
The Simple "Male to Male" Cable
This is what most people need. It has the old-school rectangular USB-A plug on one end and the small, rounded USB-C plug on the other. You’ll find these in lengths ranging from 3 feet to 10 feet. Pro tip: 10-foot cables are great for the couch, but they often have slower charging speeds because of the resistance created by the extra length. If you want fast charging, stick to 3 or 6 feet.
The Small Adapter Plug
These are tiny little nubs. One side is a USB-C male plug, and the back is a USB-A female port. These are perfect if you have an old thumb drive and a new laptop that only has USB-C ports. Walmart usually keeps these near the laptop accessories rather than the phone chargers. Brands like Blackweb (another Walmart brand) or Satechi are common here.
The Fast Charging Lie
Walmart shelves are covered in "Fast Charge" stickers. It’s mostly marketing fluff.
The reality is that USB-A to USB-C is inherently limited. Most of these cables will cap out at about 12W to 15W of power. If you’re trying to charge a Samsung Galaxy S23 or an iPhone 15 (which now uses USB-C), you really want "Power Delivery" (PD). But here is the kicker: Power Delivery usually requires a USB-C to USB-C cable, not the USB-A one you're likely looking for.
If you stick with a usb to usb c walmart cable, you're likely getting "standard" fast charging. It’s fine for overnight, but don’t expect it to juice your phone to 50% in twenty minutes. For that, you’d need to upgrade your wall brick to a USB-C version and buy a C-to-C cable.
Real World Testing: Onn vs. Name Brand
I’ve spent way too much time testing these things with a multimeter. A few years ago, the "Onn" cables were notoriously flimsy. Today? They are surprisingly adequate for 90% of users.

- The Onn Braided Cable: It’s stiff. That’s actually a good thing. The braiding prevents the internal copper from fraying. At around $7-$10, it's the best value in the store.
- Belkin: You’re paying for the warranty. If a Belkin cable dies, they are usually pretty good about replacing it. Is it worth double the price? Only if you’re traveling a lot and putting the cable through hell.
- The "Checkout Lane" Specials: Avoid these. You know the ones—the neon-colored, unbranded cables right next to the gum and candy. They often lack the proper 56kΩ resistor and use thinner gauge wire that gets hot during charging.
What to Look for on the Packaging
When you're scanning the shelf, look for these specific keywords:
- USB 3.0 or 3.1: This refers to data speed. If you’re just charging, it doesn't matter. If you’re moving photos from your phone to a computer, it matters a lot. USB 2.0 (the cheap ones) is painfully slow.
- Braided: It lasts longer. Simple as that.
- Strain Relief: Look at the part where the wire meets the plug. If it’s long and flexible, the cable won’t snap there.
Dealing with Walmart’s Inventory
Walmart's website and their physical stores are two different worlds. If you search for usb to usb c walmart online, you’ll see thousands of third-party sellers. Be careful. Many of those are shipping from overseas and aren't actually "Walmart" products. They might take three weeks to arrive.
If you need it today, check the "In-store" filter on the app. Most Supercenters keep a dedicated "Mobile Juice" section near the electronics counter. If it's not there, check the clearance endcaps. You can often find high-quality cables there for half price because the packaging was slightly crushed.
Compatibility Nuances
Here is a weird one: Not all USB-C ports are created equal. If you are trying to use a usb to usb c walmart adapter to connect a monitor to your laptop, it probably won't work. Most USB-A to USB-C connections do not support "Alt-Mode DisplayPort."
Basically, you can use these cables for:
- Charging phones and tablets.
- Moving files to a PC.
- Connecting a mouse or keyboard.
You cannot use them for:
- Connecting a laptop to a 4K monitor.
- High-speed Thunderbolt 3/4 data transfers.
- Powering a high-draw device like a gaming laptop.
Making the Final Call
Buying tech at a big-box retailer feels like a chore, but it doesn't have to be.
If you are in a rush, just grab the Onn Braided USB-A to USB-C cable. It’s the safest "cheap" bet. If you have an extra ten dollars, look for an Anker Powerline cable in the same aisle. Anker is widely considered the gold standard for third-party cables by experts at Wirecutter and various tech forums for a reason. Their connectors fit tighter, and they don't wiggle loose over time.
Actionable Steps for Your Next Trip
- Check your wall brick first. If your wall plug is the old rectangular style, you need a USB-A to USB-C cable. If the hole in the wall brick is small and rounded, you actually need a USB-C to USB-C cable. Don't buy the wrong one and have to come back tomorrow.
- Feel the cable through the box. If it feels like a thin spaghetti noodle, put it back. You want something with some girth to it.
- Look for the "USB-IF" Certification. This is a logo that means the cable has been tested by the official USB standards body. It’s the ultimate "peace of mind" stamp.
- Avoid the 10-footers unless necessary. They are tempting, but the voltage drop over that distance means your phone will charge significantly slower than it would with a standard 3-foot or 6-foot cable.
- Test it in the car. If you're buying it for Android Auto or Apple CarPlay, data speed is king. Buy a cable labeled "USB 3.1" to ensure the connection doesn't drop every time you hit a pothole.
Investing ten minutes of attention now prevents a dead battery later. Most of these cables are under $15, so while it's not a huge financial risk, the frustration of a slow charge is real. Stick to the braided options, check for the right connectors, and you'll be fine.
