Power supplies can be used with batteries, but they will not charge them; for that, you need a battery charger. Another difference is that power supplies typically have higher wattage ratings than battery chargers.
A battery charger is effectively a power supply. As long as the battery charger can provide the sufficient amount of voltage and current to the electrical load, it can be used as a power supply. There are some differences and considerations to take into account when using a battery charger as a power supply which shall be discussed in this article.
There is a big difference between a power supply and battery charger. A power supply provides power to an electronic device, while a battery charger charges a battery. A power supply converts AC or DC into low-voltage DC, which is then used to power an electronic device.
The power supply can be used by anyone from the maker in their garage, to the experienced engineer prototyping new ideas. But, good quality power supplies can be quite expensive and acquiring one might leave a dent in your bank account. Are there any alternatives to using a power supply? Can you use a battery charger as a power supply?
A 12-volt charger is designed to charge a battery, not to provide power to a device. It doesn’t have the capacity to provide enough current to run most devices. If in case you try to use a 12-volt charger as a power supply, you’ll probably find that it doesn’t work or that it works very slowly.
A power supply is a device that provides electricity to an electrical device. It converts one form of energy into another, typically converting AC (alternating current) into DC (direct current). Power supplies are used in a wide variety of electronic devices, from computers and servers to cell phones and tablets.
