Faulty charging cord for Bluetooth speaker

Hi,

Usually most devices are +ve centre.

According to the user manual it requires 5V DC from a USB port or an adapter.

If using a universal adapter here’s an image of what symbol to look for on the adapter to find out the polarity of the supply. Sometimes universal adapters have reversible and not fixed plugs so be aware of this if yours has this feature. Check what is shows on the plug!

The other thing to be aware of is there are two DC plugs that are very similar in size and it is hard to tell by just looking at them. They are 2.1mm and 2.5mm.

Unfortunately a 2.5mm plug will fit into a 2.1mm socket but there will be at best only an intermittent connection which may result in problems. The 2.1mm plug will not fit in the 2.5mm socket because the centre connector of the plug will not fit over the centre pin of the socket.

I cannot find a replacement charge cord online and it also doesn’t state the polarity or the plug size in the manual, so you may just have to try it for size and see if it works. Just ensure that the polarity is centre +ve as this is the most common connection.
