Why can I only charge with an A to C cable, not a C to C cable?
Q: I tried charging my player with a fast charger (USB‑C port) and a C to C cable, but it doesn’t work. When I switch to an old charger (USB‑A port) with an A to C cable, it charges fine. Why?
A: Because the two types of ports communicate differently.
-
USB‑A port (the older rectangular one) is simple: it just sends power. The player sees the power and starts charging.
-
USB‑C port (the newer oval one) is smarter: when you plug it in, the charger first asks the device, “How many volts do you need?” If the device doesn’t answer, the charger won’t send any power.
Our player, to save cost, size, and battery life, does not include the chip that answers that question. So when the charger asks, it can’t reply. The charger waits, gets no response, and stays off.
When you use an A to C cable, the USB‑A port never asks questions – it just delivers power, and the player charges normally.
Q: So what should I do to charge my player?
A: Simple rule: always use a USB‑A charger (or port) with an A to C cable. For example:
- Most phone chargers that are not tiny fast‑chargers have a USB‑A port.
- The USB‑A port on your computer.
- The USB‑A port on a power bank.
If you only have C to C cables, you can buy a small USB‑C to USB‑A adapter and plug it into a USB‑A port.
Q: Is my player defective?
A: No. This is a normal design choice for many small electronics (MP3 players, Bluetooth earbuds, smart bands) to keep costs down, reduce size, and save power. The user manual clearly states to use an A to C cable. Follow that, and you’ll be fine.
Q: Can a firmware update fix this?
A: No. This is a hardware limitation – the chip that handles the USB‑C “handshake” is missing. Software cannot add it. Just keep using A to C charging.
One‑sentence summary: Always charge your player using a USB‑A charger and an A to C cable. Do not use C to C cables with USB‑C fast chargers or laptop ports.
