Is it okay to use higher voltage 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 19V charger on a 15v laptop?

It should be okay. It is not a good idea to use a charger with a different voltage rating as this may cause damage to the laptop, or it may not supply any charge at all if the voltage is low.

Can you use a 12V adapter for a 19V device?

A 12V adapter is unlikely to damage the components, but it is possible depending on the design and that’s why I mentioned it. The likelihood is probably vey tiny though so you can probably ignore that bit.

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?

How does a laptop charger work?

There are few basic steps in a laptop charger. The laptop charger is a switch mode power supply that is basically a power supply that first converts the AC 220V to DC voltage. Thats nearly 330 Volts. Now this DC voltage is fed to two transistors that switch the DC voltage to alternating current again.

What type of power do I need to charge my device?

The input line voltage (wall or “mains” power) must be supported but is unrelated to compatibility with the device being charged or powered. The voltage provided by your charger must match that expected by the device being charged.

What should I look for when buying a laptop charger?

Don’t plug in a charger with a significant difference in voltage output. The amperage output should be equal or greater to your laptop’s requirements. You can connect a charger that delivers more watts or amps than your computer needs since your laptop won’t draw more power than it needs.
