How many times have you run out of battery in the middle of the countryside and have nowhere to charge it? With this practical article you will learn how to make your own battery charger.

What we need to create our loader is:

The next step is to soldering the battery holder wires. To do this we put one on each flange of the plug (where the old cables were attached) and solder carefully. At this point we must find out which is the positive and which is the negative, because if we confuse them, we could burn the battery.

Now plug the connector with its old casing and we insert all the batteries. Regarding the batteries, they should be approximately the same voltage as the original charger. For example, if our mobile phone charger works at 3.6 V, we will not be able to insert 14 V batteries in our battery holder, but we could insert 4 V batteries, for example.

In the end, all that remains is test our charger to see if it is working properly.

I would like to add that this trick could be adapted to many other electronic devices that also use a charger, we would only have to worry about the plug being compatible and the batteries have the suitable voltage.
