There are a few possible explanations. First, it could be seen as an environmental move. By not including chargers, manufacturers are cutting down on the amount of waste produced. This is a good thing for the environment, but it does create an inconvenience for consumers.
Another possibility is that manufacturers are trying to save money. Chargers can be expensive to produce, so by not including them, manufacturers can keep the price of their products down. This might be good for consumers in the short term, but it’s not a sustainable long-term solution.
The last possibility is that manufacturers are simply trying to get us to buy more stuff. By not including chargers, they know that we’ll have to buy them separately. This is an annoyance, but it’s also a way for manufacturers to make more money.
Whatever the reason, the trend of not including chargers with new electronics products doesn’t seem to be going away anytime soon.
