Every cell phone, laptop, and tablet seem to come with their own charger. If you’re like me, you’ve probably compiled quite a few chargers over the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that isn’t the original manufacturer’s charger that came with the device? Types of Chargers In this article, we will focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most common. Laptop chargers are fairly specific to the device they come with. However, there may be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of the charger “head” and may not be the optimal charging amperage or voltage for your device. Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the same voltage, but may draw different amps. I’ll explain this further later and how to know if the charger is safe to use (depending on its listed amps and voltage).
