TVR 14471 varistor was the original, which is a 300 Vrms varistor. If I remember well, the fuse was 3.15AT. But keep in mind, the varistor voltage and the fuse type depend on the designed mains voltage of charger. So, you have to install parts of the same value as what was in it. This charger in the video is designed for 200-240V, and I installed the varistor from a Dell desktop PC power supply.
I have a problem with the same charger for my ebike. The charger turns on after connecting to the power supply, then the diode lights up red, then green and again red, then turns off. Inside you can hear how the processor works. Is there a possibility of repairing it? Please help and contact me in my case. Best regards
In the case of industrial electronics, it is worth repairing power supplies and PCBs costing thousands of euros, and spending time reverse engineering the operation. I repaired this power supply as a hobby, its owner has already bought another one, because she was told in the service center that it cannot be repaired. It's not a cheap power supply though, it costs at least 400 euros. I couldn't find any documentation for it at all, so it is much slower to diagnose the device. So the question is not so much whether it can be fixed, but how long it takes and whether it is worth spending a lot of time with it.

what is the spec for the varistor and fuse?
