What happens if the amperage is too high?

What happens if the amperage is too high?

When output current needs to be higher, it will stop acting as an ideal voltage source and will start showing imperfections such as voltage drop, overheating, current limit and so on. Voltage and resistance is all that matters. So, given a fixed voltage and the fixed resistance you can calculate amperage.

Can I use 2a charger for 1.5 a device?

Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed.

What happens if you use the wrong laptop charger?

Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. Using a charger with too low current rating might fry the power supply, but not the laptop. As the difference in voltage in this case is small, it should be OK.

Can I use any Dell charger for my laptop?

Not all Dell laptop chargers will work on all Dell laptops, because the individual models vary in power source requirements. The chargers, while paired with compatible models, are designed to work with all laptops that use the same type of connection and require the same power output.

Can I use a 90w adapter on a 65w Dell laptop?

Yes, you can use a 90 watt ac adapter, a.k.a power charger, for your 65 watt-compatible laptop. It will actually charge your battery faster.

Can I use a 65w charger instead of 90w Dell?

Distinguished. If its the same voltage, then you can use it. But if you are using more power then it can provide, your laptop will start drawing from the battery as well as from the power brick.

What’s the difference between 90w and 65W AC Adapter?

The one main difference between both of them is the current it can source while charging at the same voltage. Yes, a 90 watt charger can charge quickly when compared with a 65 watt charger. The one main difference between both of them is the current it can source while charging at the same voltage.
