Charge cable for Polaroid PA80 Smart watch

I got a Polaroid PA80 Smart watch as a present the watch I am happy with but have had to replace the charge cable three times already now this cable has 5 V at the charge point but it will not charge the first cable broke in the middle and started to burn the cloth luckily I was around otherwise it might have caused a fire the next cable over heated at the charge point and melted the plastic rendering the cable use less I do not abuse the cables I am very un happy
