| Pros | Cons |
|---|---|
| Sleek head design and nice finish | Unstable data speeds and charging |
| Available in multiple colors | USB2 speeds despite 240W spec |
| Flexible and lightweight | |
| Included silicone cable tie |
We’ve generally liked Anker products in the past, but their 240W Nano USB-C cable? Honestly, it raised a lot of red flags during testing. On paper, it checks all the boxes. It’s 240W charging, good looks, and a compact design. But when we put it through our usual gauntlet of performance and durability tests, things didn’t hold up. If you’re thinking of picking one up, you’ll want to hear this first.
Design
| Advertised Length | Measured Length | Cable Type | Charging Spec | Connector Material | Flexibility |
|---|---|---|---|---|---|
| 0.9m | 0.95m | USB 2.0 | PD 3.1 | Full Metal Head | Flexible (braided) |
At first glance, the Anker Nano cable looks great. It’s thinner than most 240W-capable cables, has a clean matte finish, and comes in a range of colors. The connector head is nicely designed too. It’s also super flexible but maybe too flexible for our liking. It flops around more than we’d like, which might be an issue in more rugged setups. Anker lists it as 1 meter long, but ours measured 1.03 meters so you’re getting a bit more length than advertised.
Performance
| Test | Pre-Bend | Post-Bend |
|---|---|---|
| Voltage Drop | 0.74V | 0.79V |
| Resistance | 0.190 Ω | 0.21 Ω |
| Large File Write Speed | 27.2 MB/s | 27.1 MB/s |
| Large File Read Speed | 30.1 MB/s | 29.6 MB/s |
| 1GB Folder Write Speed | 26.9 MB/s | 26.7 MB/s |
| 1GB Folder Read Speed | 29.9 MB/s | 29.8 MB/s |
| 5GB Folder Write Speed | 27.2 MB/s | 27.1 MB/s |
| 5GB Folder Read Speed | 30.1 MB/s | 29.6 MB/s |
Charging results were disappointing from the start. It struggled to hit the 15W charging protocol, and the average voltage drop was 0.81V which was much higher than our 0.69V average. Resistance came in at 0.24 ohms, also higher than expected. These are early warning signs before even running durability tests. As for data, large file transfer speeds were nothing special: 26 MB/s write and 30 MB/s read. One run even dropped to 7 MB/s, which no other cable in our test group did. In mixed file tests, write speeds were decent at 40 MB/s, but the inconsistency flagged this as unreliable.
Durability
| Rated Bends | Bends Tested | Visible Wear | Functional |
|---|---|---|---|
| 300,000 | 330,000 | Slight connector bend | ✅ Yes |
Anker claims the cable can withstand 30,000 bends but we tested it to 33,000 just to be safe. Surprisingly, it looked fine. But visually passing doesn’t mean much. In post-bend charging tests, the cable failed to initiate in 19 out of 20 attempts. The one successful connection showed a massive 6V voltage drop and resistance spiked to 1.32 Ω. Basically, unusable. The strange part? Data tests improved. Write speeds were steady, but read speeds jumped from 40 to 944 MB/s in one test. It’s possible the internal chip was damaged and stopped throttling the connection. Wild, but not exactly confidence-inspiring.
Value
At $19.99, this cable is slightly above the average $20.50 for its category. It comes with a nice silicone tie, but that’s about it. Given the inconsistent results and how quickly it failed under testing, it’s hard to recommend. Even if you like the styling or brand name, there are simply more reliable choices out there at the same price point.
Verdict
The Anker 240W Nano cable is a textbook example of form over function. It looks good, it feels flexible, and it survived the bend test visually but internally, it fell apart. Poor voltage stability, failed charging connections, and erratic data performance make it tough to trust. For something that’s supposed to handle high-power tasks, this cable just doesn’t deliver where it counts.
