One Of The Best USB-C Cables I've Tested – Mophie Charge Stream USB-C/USB4 Cable Review

I’m not a big fan of Mophie’s battery banks but their cables are something else. The Mophie Charge Stream is a beast of a cable…except for one thing.

Mophie Charge Stream USB-4 USB-C to USB-C Cable Heavy-Duty Braided Enduraflex Silicone 240W Power Delivery Review

-The Charge Stream is a USB4 cable that has the potential for 240W charging
-the head of cable has a metal cap with the rest of the body being a matte rubber
-the head size is smaller than other USB4 cables which means it’s easier to use
-i was surprised with the length, Moophie said it was this (0.8), I got this (0.89)
-Becuase it’s a USB4 cable, it’s bulkier but it has a nice flex to it so again, easier to use

-For charging, this cable was solid out of the box
-Didn’t encounter an failed protocols when I called for them
-One of the few cables that didn’t fail the 15W charging test
-though the voltage drop on the higher 15V and 20V charge protocols did have slightly higher voltage drops but nothing to be concerned about ( .64 vs .69)
-The average resistance in the cable was also average as well (.21 ohms)
-For large data files, it was average for both write and read speeds at (238 and 234)
-I’ll add that every test I did was consistent. It was 238 and 234 on the nose which was neat to see
-For the 1GB and 5GB mixed folder tests, the speeds were average as well
-When it came to charging, at 3300 bends, the results were almost identical to the fresh out of the box results
-At 11k bends, everything up to 60W was fine, I couldn’t get the cable to give me 20V at 5A.
-if we compare the before and after’s, there was a noticeably voltage drop by about .12 volts which, if charging your iPhone, is going to add 30 seconds on a full charge so relatively not a big deal
-everything else was the same for charging
-for data, after 3.3k bends, the speeds were basically identical
-at 11k bends, the speeds for the large files were a hair slower between .5 to 1.5MB/s so not a huge deal but worth noting
-I’ll say same with the mixed file data transfers as well
-so a noticeable degradation, albeit minor ones, after bending it 3x times the stated amount
-Not bad

General Testing Procedure:
Data:
– Data speeds were tested with a Samsung T9 Portable SSD connected to a M1 Mac Studio
– Tested 1, 5, 20 GB sized files and 1, 5 GB folders containing mixed files
– Data speeds were measured using fio
Charge:
– Charge speeds were measured using a 140W Apple Charger, a PowerZ KM003c and a Siglent Eload
– Charge speeds measured across 15, 27, 45, 60W rates
Bends:
– Bends were tested on a custom built bending platform
– Cables were bent to 90 degrees repeatedly, no pause at each bend
– Cable wasn’t hard clamped, it was held in place by a channel in the platform to allow for a bit of twisting
