Any different between power supply and battery charger?Thanks!!
Greetings, My name is Tom, known as HD116 at Home Depot's How to Community found at the site below. The fact is that the old charger will not work on the lithium ion batteries, but the charger for the lithium ion batteries will work for the old NiCad batteries with every manufacturer I have seen so far. There may be an exception, but I have yet to see one. Hope that helps.
For the brick/box part, no. They are both the same animal. The circuitry around the battery charger to prevent battery overcharging and discharge (reverse flow) is contained within the box that holds the batteries (either the phone/camera/mp3 player or an actual battery charger). If you plan to try and use one for the other, make sure the output voltages are the same, as well as the polarity (many larger pieces of eqt will have a little diagram next to the power plug-in). However, to decipher that, it'll unfortunately require another question. The amperage should also be in the same ballpark, as that'll also affect the amount of juice the power supply designed to provide. Good luck!
Power supply is supposed to provide sufficient power for the device and provides stabile output voltage. It can be AC or DC output. With additional circuitry an PS may be used *** battery charger. Battery charger always has DC output and depending of battery it is supposed to charge , can provide different output. Some batteries require contant voltage to charge some , regulated current. Some chargers do not have a filtered output. Typically they are not replacement for power supply.
Yes. A battery charger usually incorporates a power supply, but a power supply isn't always a battery charger. A power supply is a bit of a misnomer - typically it refers to circuit that converts ac to dc or dc to ac, and either steps the voltage up or down as necessary. More literally, any form of energy storage could be called a 'power supply': a lump of coal, a wooden log, or a battery itself, as all of these objects can 'supply power'. A battery charger needs to provide a specific dc voltage or current, and may be required (by battery chemistry) to control voltage and current based on time (duration) or temperature.
A battery charger is used to recharge rechargable batteries, such as lithium and (to a lesser extent) nickel-cadmium. A power supply is generally a plug-in-the-wall substitute for batteries, which does not allow the device to be portable. However, a battery charger has a power supply which converts AC to DC in order to charge the batteries. A power supply is anything which supplies voltage to a circuit.
