Today let's look at how to transform battery-operated Christmas lights to run on a USB charger, such as that of a smartphone or iPhone. This is because lights that run on batteries have become very popular in recent years, and although they cost less than those that run on 230v, they use up a lot of disposable batteries, which are expensive and very harmful to the environment. So if we already have battery-operated lights at home but want to power them with mains electricity, which is much cheaper than batteries and less polluting, we can do it very easily by following this video.
