One with the proper electrical ratings will work with your device. The output voltage and current of the adapter must match those of the device. To find out the device’s recommended voltage and current, see the product label or user guide.

You can use a greater wattage adapter as long as the voltage and connector type are the same. Although the battery may charge a little bit more quickly, you won’t notice any other differences outside the brick’s size.

You can use a 65W, 90W, 120W, 150W, 180W, or 240W charger if your laptop came with a 65W charger because we know it won’t ever require more power than that.

The gadget can turn on and then use more current than the adapter is rated for. The adapter can overheat or break as a result of this. Alternately, the device might turn on but the adapter might not be able to keep up, resulting in a drop in voltage (see voltage too low above).

4You may test and compare connector sizes in stores, or if you’re technically inclined, you can measure the port and pin sizes yourself. If you are measuring, you need to know the inner diameter of the port as well as the diameter of the center pin for the (ID) (OD).

Your laptop could sustain damage if you use a charger with the incorrect voltage rating. Too much voltage is often to blame for this. However, utilizing an excessively high current charger won’t harm your laptop. The power supply could be damaged if a charger with a low current rating is used, but not the laptop.

You may use the 65W charger included with Oppo and One Plus devices to charge your compatible laptop, Nintendo Switch, and even your Galaxy phone because it supports the USB-C PD standard with speeds of up to 45W.

Despite the fact that the voltage is different, they are probably interchangeable. This is due to the fact that the voltage differential is within specifications, and I GUESS you could go further higher or lower.

Amperage is derived from how much current is actually taken, based on the device’s resistance, therefore having “too much” is not a problem and would not harm. A greater voltage than a device is designed for will most likely blow up some components.

It only takes a moment to examine the charger directly. The wattage may be printed on this (as on Apple chargers), but the output(s) may be stated in volts and amps. Because Watts = Volts * Amps, if it states the output is 5V at 3A, for instance, it is a 15W charger.

The voltage capacity of the adapter must not exceed 10% of the computer’s capability. Wattage Range: The computer’s and the adapter’s wattages must be equal. Current Range: The computer’s current should never be less than the power adapter’s current.

Each power adapter is capable of handling and delivering a given amount of power, measured in watts or volts, to a certain device. A power adaptor is not universal as a result. Different power adapters cannot be combined or switched between devices. The auxiliary battery won’t function.

Not all USB chargers, cables, and connectors are created equal. For instance, some wall chargers can deliver more power than others, and the power of a specific USB port on a laptop may differ from the power of the others, or some PCs can charge while they are in sleep mode. You should also think about amps.
