Yes, a power supply can charge a battery directly. The charging process will be slower than if you were to use a dedicated battery charger, but it will work. You’ll need to make sure that the polarity of the power supply is correct for the battery – check your documentation to be sure.
Yes, you can use a switching power supply to charge a battery. However, there are some things to keep in mind when doing this. First, the voltage of the power supply must be higher than the voltage of the battery. Second, the current output of the power supply must be greater than or equal to the charging current of the battery.
If you often find yourself without the charger you need, consider investing in a universal adapter to avoid further issues. All you have to do is match your laptop’s tip and voltage settings and plug it into a power source like a wall outlet. An external battery charger provides a direct way to charge your laptop’s battery outside of the computer.
One way is to use a 12V charger that plugs into the outlet. Another way is to use a cigarette lighter adapter and plug it into the outlet. Finally, you can use jumper cables and connect the positive and negative terminals of the battery to the corresponding terminals of the outlet.
For an Android device with removable battery, is it possible to use only in charging mode (wall charging with the device's charger/USB charging) after removing its battery? (For example, a laptop can be run by direct plugging, without battery) I would say that this depends on the phone.
Yes, you can charge a laptop with a USB if it supports USB-C Power Delivery. This feature allows high-wattage power transfer, allowing devices like smartphones, tablets, and even some laptops to charge each other. Note that traditional USB-A ports do not provide sufficient power for charging laptops.
