Causes The adapter is rated USB 3.2 Gen 2 (10 Gbps), but the whole chain decides the real speed: the cable inserted into its female end, the laptop port, and the device all have to be USB 3.x or the link silently falls back to USB 2.0's 480 Mbps. The 10cm extension's four SuperSpeed pairs are thin and sit inside the 90° joint — a partially seated head, dirty inner pins, or a micro-crack from repeated bending all force the same USB 2.0 fallback while charging keeps working, so files copy at 30-40 MB/s instead of 800+ MB/s and the adapter gets blamed...

Causes The PowerExpand is a passive cable, not a video converter — it can only pass DisplayPort Alt Mode through if every link in the chain carries it: the laptop's USB-C port must output DP Alt Mode, the 10cm extension's four SuperSpeed lanes and SBU pins must be intact, the cable in the female end must be rated for video, and the monitor must be on the right input. A USB 2.0-only cable, a port that is charge-only, a broken high-speed pair inside the extension from repeated bending, or a partially seated head all kill the signal while charging and data still work — the classic 'charges fine, but no picture' symptom...

Causes The 10cm braided extension acts as a lever on the 90° head: any bump or tug briefly breaks contact on the CC and data pins, so charging restarts and drives unmount. A head that isn't fully clicked into the port, lint or wear inside the device port, a weak female socket on the adapter, or a partially broken wire pair inside the extension all show up as intermittent drops that only happen when the cable moves...

Causes The adapter is fully wired for USB 3.2 Gen 2, but data only passes if the cable plugged into its female end carries data wires — phone-charger cables are often charge-only, and a USB 2.0 cable caps the whole chain at 480 Mbps instead of the adapter's 10 Gbps. An Android phone set to 'Charging only', dirty data pins, or the high-speed pairs snapped inside the 10cm extension after repeated bending at the 90° joint all produce the classic 'charges but no data' symptom...

Causes The PowerExpand's 10cm braided extension adds an extra plug between your charger and device, and 100W PD pass-through only works if the e-marker and CC pins are read end-to-end — a partially seated 90° head, a charger or cable rated below 100W upstream, or lint blocking the device port's CC pin all break negotiation, so the device falls back to 5V and charges slowly or not at all. A cracked power rail inside the 90° joint from repeated bending produces the telltale 'charges only at one angle' symptom...
