INIU Swooshcord USB-C Cable Review: Cheap Price, Unreliable Performance

Longer than advertised

When a USB-C cable promises 240W charging and comes in at under $10 a piece, it sounds like a steal. But here’s the thing: with the INIU Swooshcord USB-C cable, you really do get what you pay for. We ran it through our full suite of tests and while it looks solid on paper, real-world usage exposed some serious flaws. Let’s break it down.

At a glance, the INIU Swooshcord feels like it should perform well. It’s thick, braided, and comes with a full metal connector head. We ordered the 2-meter version, and it actually measured 2.02 meters. The cable is also stiff enough to hold its shape, which some might find useful for tidy routing. However, each connector head looked slightly different, which felt a bit inconsistent. Most notably, while it supports PD 3.1 and claims 240W charging, INIU doesn’t state its USB version on the box. We only learned it was USB2 during testing.

Charging tests didn’t go as well as we’d hoped. Out of eight power delivery protocols, it failed three. It struggled with the 100W profile in particular, which isn’t great for something claiming high-wattage compatibility. Voltage drop came in at 0.73V (higher than average), and resistance measured 0.22 Ω. On the data side, write speeds were slightly above average, but read speeds were just below average. The real issue was with mixed file transfers. Transfer speeds dropped off a cliff, which is a major red flag if you’re using this for anything beyond simple charging.

Durability

INIU claims the cable is bend-rated for 45,000 cycles. We went 10% over, hitting just shy of 50,000. The cable felt slightly looser after testing but didn’t show any visible damage. Surprisingly, the charging performance didn’t change much post-bend. The voltage drop shifted by just 0.01V, and resistance remained the same. But data performance got even worse. Large file write speeds dropped to around 19 MB/s, and read speeds to 22 MB/s. Mixed file tests were similarly poor, making the cable effectively unusable for data.

Value

Here’s the kicker: this is an $18 two-pack. That’s $4.46 per meter—absurdly cheap. But cheap doesn’t equal good. You’re trading cost for reliability. It’s hard to justify using a cable that flunks both power and data performance, even if it’s practically disposable. There are better cheap cables that can at least maintain USB3 speeds and hit power specs more consistently.

Verdict

The promise of USB-C is that it’s universal with one cable to charge and transfer data across all your devices. But INIU’s cable feels like a universal failure. It’s affordable, sure. But charging is inconsistent, and data speeds are embarrassingly bad, especially after stress testing. We can’t recommend it for anything beyond emergency backup use. Even then, we’d still hesitate.
