When I first came across the WhatCable post on Hacker News, I did something embarrassing: I walked over to my desk, picked up three USB-C cables sitting in a pile, and realized I had absolutely no idea which one was the 100W charger and which one had been limping along at 5W for the past eight months. The show WhatCable tiny menu inspecting tool hit a nerve because it solved a problem I didn’t know had a clean solution. As a Canadian Mac user with a drawer full of cables bought off Amazon.ca over the years, having a free app that reads what a cable actually does — right from the menu bar, in plain English — is genuinely useful. This review covers the app itself, and then pairs it with the five best USB-C cables you can actually buy in Canada today.
Key Takeaways
- WhatCable is a free, open-source Mac menu bar app (built in Swift/SwiftUI) that identifies your USB-C cable’s real capabilities: charging wattage, data speed, display support, and Thunderbolt level.
- USB-C cables vary wildly — from 5W passive cables to 240W / 40Gbps Thunderbolt 4 cables — and they look identical. WhatCable removes the guesswork.
- All five cables in this guide are available on Amazon.ca with Canadian fulfillment, priced between $12 CAD and $59 CAD.
- For most Canadian MacBook users, the Anker 240W USB-C Cable (~$22 CAD) is the best everyday value; for Thunderbolt 4 workstation setups, the Apple Thunderbolt 4 Pro Cable (~$59 CAD) is the clear pick.
- WhatCable has no tracking, no subscription, and no App Store gatekeeping — download it free from GitHub.

What Is WhatCable? The Free Mac Menu Bar Cable Inspector
WhatCable is a tiny macOS menu bar application built by developer Darryl Morley in Swift and SwiftUI. The premise is straightforward: plug in a USB-C cable and the app reads the cable descriptor data your Mac already has access to, then displays it in plain English. You see the charging wattage ceiling, the data transfer speed, whether the cable supports DisplayPort alt mode, and whether it’s Thunderbolt 3 or Thunderbolt 4 certified. No digging through spec sheets. No squinting at fine print on Amazon listings.
What surprised us when researching this was how much variance exists even among cables sold as “USB-C.” The USB-C connector standard technically allows for cables rated anywhere from 5W passive charging up to 240W (under the USB Power Delivery 3.1 spec finalized in 2021) and data speeds from USB 2.0’s 480Mbps all the way to Thunderbolt 4’s 40Gbps. Two cables can look physically identical and perform at opposite ends of that spectrum. WhatCable reads the e-marker chip embedded in higher-spec cables — the chip that stores the cable’s actual rating — and surfaces that data immediately. The app is open-source on GitHub (github.com/darrylmorley/whatcable), free, and has zero telemetry or tracking.
For Canadian developers and Mac power users, this pairs directly with having a reliable set of USB-C cables you can trust. If you’re running a MacBook Pro M3 or M4 connected to an external display and a 140W charger, knowing your cable is actually rated for that load matters. The five cables below were selected specifically because they cover the full range of use cases WhatCable will report on — and all are available on Amazon.ca with Canadian fulfillment.

1. Anker 240W USB-C to USB-C Cable
Anker’s 240W USB-C cable is the one to buy if you want a single cable that WhatCable will report back on with maximum capability. It’s rated to the USB Power Delivery 3.1 standard at 240W, handles data at USB 3.2 Gen 2 speeds (10Gbps), and comes in lengths from 0.9m to 1.8m. The braided nylon exterior is noticeably more durable than the rubber-coated cables that come bundled with most chargers. Anker backs it with a lifetime warranty — a detail worth noting given how often cheaper cables fail at the connector joint within six months.
The e-marker chip in this cable is what makes it readable by WhatCable. Plug it into your Mac and the app will correctly identify it as a 240W-capable cable rather than showing a generic or unreadable result. That matters if you’re using a high-wattage GaN charger — the Anker 747 charger, for instance, outputs 150W on its USB-C port, and pairing it with an underpowered cable means your MacBook Pro throttles the charge rate without telling you why. At roughly $18–$25 CAD on Amazon.ca depending on length, this is exceptional value.
Specs: 240W max, 10Gbps data, USB 3.2 Gen 2, nylon braided, available in 0.9m / 1.8m. Pros: highest wattage rating in this price range; e-marker chip for full WhatCable readout; lifetime warranty; widely available on Amazon.ca. Cons: does not support Thunderbolt 3 or 4 (data only, not TB-certified). Best for: Canadian MacBook users who want a reliable everyday charging and data cable without spending $50+.

2. Apple Thunderbolt 4 Pro Cable
Apple’s Thunderbolt 4 Pro Cable is the reference-grade option. At 40Gbps data throughput, support for dual 4K displays or a single 6K display (Pro Display XDR territory), and 100W charging, it does everything the USB-C spec allows at the Thunderbolt 4 tier. WhatCable will return the fullest possible readout on this cable — Thunderbolt 4 certified, 40Gbps, 100W, display support confirmed. It’s 1.8m long, which is generous for a desk setup, and the build quality is exactly what you’d expect from Apple: thick, tightly braided, with reinforced connector housings.
The accepted narrative is that Apple charges a premium purely for the logo. The actual case is more nuanced: Thunderbolt 4 certification requires Intel’s testing and licensing process, and counterfeit or uncertified TB4 cables are a real problem on Amazon marketplaces globally. Buying directly from Apple or from Amazon.ca’s Apple-authorized listings gives you verified certification. At $55–$65 CAD, it’s the most expensive cable in this guide. If your workflow involves an eGPU, a Thunderbolt dock, or a 6K display, the cost is justified. For charging a MacBook Air, it’s overkill.
Specs: Thunderbolt 4, 40Gbps, 100W charging, 1.8m, dual 4K / single 6K display support. Pros: certified TB4; maximum WhatCable readout; Apple build quality; dual-display support. Cons: $55–$65 CAD is a significant premium over 100W alternatives; 100W cap means it won’t fast-charge newer 140W MacBook Pro models at full rate. Best for: Mac Studio, Mac Pro, or MacBook Pro users with Thunderbolt docks or external 6K displays.

3. Belkin BOOST↑CHARGE PRO Flex USB-C Cable
Belkin’s BOOST↑CHARGE PRO Flex is the travel pick. The silicone outer jacket is genuinely flexible — it coils flat, doesn’t retain kinks, and survives being stuffed into a laptop bag repeatedly without the connector joint stress that kills braided cables over time. It’s rated at 60W (USB Power Delivery), handles USB 2.0 data speeds (480Mbps), and comes in 1m and 2m lengths. WhatCable will read it as a 60W cable — not the highest wattage here, but sufficient for MacBook Air and most iPad Pro charging scenarios.
The 60W ceiling is the honest limitation. If you’re running a MacBook Pro 16-inch that wants 140W to charge at full speed, this cable will charge it — just slowly under load. Belkin prices this at $28–$38 CAD on Amazon.ca, which is reasonable for the build quality and the flexibility advantage. Belkin also sells into Best Buy Canada and Staples Canada locations, so it’s one of the easier cables to find in-store if you need a replacement same-day in Calgary, Toronto, or Vancouver.
Specs: 60W, USB 2.0 (480Mbps data), silicone jacket, 1m / 2m, MFi certified for Apple devices. Pros: best flexibility for travel; silicone jacket resists kinking; available in Canadian retail stores. Cons: 60W cap limits fast-charging on MacBook Pro 14/16-inch; USB 2.0 data speed only. Best for: Canadian travellers, MacBook Air users, and anyone who needs a cable that survives a laptop bag.

4. Cable Matters 100W USB-C Cable
Cable Matters is a brand that doesn’t get enough attention in Canadian tech circles. Their 100W USB-C cable supports USB 3.2 Gen 2 (10Gbps data), 100W Power Delivery, and comes in lengths from 0.5m to 2m. It’s the cleanest budget option for a desk setup where you want real data transfer speeds alongside solid charging. WhatCable will read it correctly as a 100W, 10Gbps cable — a meaningful step up from the Belkin’s 60W / USB 2.0 spec, at a lower price point.
At $12–$18 CAD on Amazon.ca, this is the cable to buy in multiples. One for the desk, one for the monitor arm, one in the bag. The build is straightforward nylon braid with aluminum connector housings — nothing exotic, but reliable. Cable Matters ships from Canadian Amazon fulfillment centres, so Prime delivery applies without cross-border complications. Our reading of the user reviews suggests the 2m version is the most popular length for desk setups where a monitor and laptop charger share a single cable run.
Specs: 100W, 10Gbps (USB 3.2 Gen 2), nylon braid, 0.5m to 2m, e-marker chip included. Pros: best price-to-spec ratio in this guide; 10Gbps data at under $18 CAD; multiple lengths; Canadian fulfillment. Cons: no Thunderbolt support; brand recognition lower than Anker or Belkin. Best for: budget-conscious Canadian Mac users who need a capable desk cable without premium pricing.

5. Baseus 100W Braided USB-C Cable
Baseus has become a legitimate option in the Canadian Amazon.ca ecosystem over the past two years — their cables show up in Prime-fulfilled listings, prices are competitive, and the build quality on the braided 100W line is noticeably better than the brand’s earlier budget-tier products. The 100W cable supports USB 3.2 Gen 2 (10Gbps), includes an e-marker chip, and comes in a tight nylon braid with a 90-degree angled connector option on some SKUs — useful if your MacBook’s USB-C port faces an awkward direction on your desk.
Priced at $14–$20 CAD on Amazon.ca, it sits just above the Cable Matters option but adds the angled connector variant as a differentiator. WhatCable will read it as a 100W / 10Gbps cable. One honest note: Baseus sells a wide range of cables and not all of them carry the e-marker chip — check that the specific listing you’re buying states 100W and USB 3.2 Gen 2. The cheaper Baseus cables in the $8–$10 CAD range are typically 60W or lower and will return a different WhatCable readout.
Specs: 100W, 10Gbps (USB 3.2 Gen 2), nylon braid, available in straight and 90-degree angled connector, 1m / 2m. Pros: angled connector option is unique at this price; e-marker chip; solid braid quality; Prime-fulfilled on Amazon.ca. Cons: Baseus product line is inconsistent — verify specs on the specific listing before buying. Best for: Canadian users who want 100W performance with an angled connector for tight desk setups.

Budget vs Premium: Which USB-C Cable Should Canadians Buy?
Best Budget Pick: Cable Matters 100W USB-C Cable (~$12–$18 CAD)
If you’re outfitting a home office on a tight budget, or you just want a reliable cable that WhatCable confirms is doing its job, the Cable Matters 100W is the answer. Ten gigabits per second data, 100W charging, e-marker chip, Canadian fulfillment. At $12 CAD for the 1m version, it’s genuinely hard to argue against buying two or three. Check price on Amazon.ca.
Best Premium Pick: Apple Thunderbolt 4 Pro Cable (~$55–$65 CAD)
For Canadians running a Thunderbolt 4 dock, an eGPU enclosure, or Apple’s Pro Display XDR, there is no substitute. The 40Gbps throughput and certified TB4 status are the difference between a setup that works and one that randomly drops display connections or throttles bandwidth. WhatCable will show you exactly what you’re getting. Check price on Amazon.ca.
The gap between $12 and $65 CAD is real, but so is the performance gap. If you’re not sure which end of the spectrum your setup actually needs, install WhatCable, plug in what you already own, and let the app tell you whether you’re leaving performance on the table. That’s the honest starting point.

| Cable | Max Wattage | Data Speed | Thunderbolt | Display Support | E-Marker | Price (CAD) |
|---|---|---|---|---|---|---|
| Anker 240W | 240W | 10Gbps | No | No | Yes | $18–$25 |

Best Overall Pick for Canadian Mac Users
The Anker 240W USB-C Cable is the best overall pick for most Canadians. Here’s the short version: 240W headroom means it won’t be the bottleneck regardless of which MacBook or charger you pair it with, the 10Gbps data speed handles file transfers without frustration, the e-marker chip gives WhatCable a full readout, and $18–$25 CAD is a price point that makes buying a spare copy reasonable. It ships from Canadian Amazon fulfillment, so Prime delivery applies and there are no cross-border complications.
The Apple Thunderbolt 4 Pro Cable is the right answer for a specific, higher-end use case — Thunderbolt docks, eGPUs, 6K displays. If that’s your setup, the premium is justified and the cable will deliver. For everyone else, the Anker 240W does the job cleanly and WhatCable will confirm it every time you plug in.
USB-C cable pricing on Amazon.ca moves frequently — especially on Anker products during Prime Day and Black Friday sales, when the 240W cable has historically dropped below $15 CAD. Check current prices before buying, because the deals do shift.
