Can I charge my laptop with a lower amperage?
The answer is yes. You definitely can use a lower wattage charger for your laptop (you can even charge your laptop without a charger!), but this will directly impact the performance of your laptop itself.
Is it OK to use a lower amp charger?
We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

Can I use a charger with lower amps?
The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. The device being charged may be damaged.

Is it bad to charge a laptop with low amperage?
That is one of the reasons why the use of low amperage charger may become an issue.. not immediately but may happen at a later time.. As long as, at the laptop’s highest current draw, the output voltage of the power supply xstays steady and doesn’t drop, then you’re fine.
Why does my laptop adapter cause more current than 18V?
However, the laptop adapter’s voltage is a full volt above the specified 18 V; this will cause more current to flow into your device, since the voltage has been increased.
Is it OK to use a higher wattage charger for laptop?
If the charger delivers more amps or watts than your computer needs, you can still use it since your computer won’t draw more power than it needs. However, it would be best to use a charger with the correct output as soon as you can replace it. Can I use a lower wattage charger for my laptop?
Can I use more amps than I need from my Charger?
To be clear: there is nothing wrong at all with having a charger capable of providing more amps than needed. The polarity of the connection between your charger and device must be correct. Most power supplies provide their output on two wires: one labeled (+) or positive, and the other (-) or negative.
