Is it okay to use a lower amperage but the same output voltage laptop charger?

Is it okay to use a lower amperage but the same output voltage laptop charger?

No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.

Can I use an AC adapter with higher wattage?

If the wattage is higher than original it won’t hurt anything (as long as Voltage is the same). If the wattage is lower than original, it may not provide enough power to charge it. Voltage must be the same. Sometimes a charger with slightly lower wattage will charge it but it will take longer.

What happens if I use a higher voltage laptop charger?

Using a higher current charger (than the laptop is rated for) will not cause damage to the laptop; as stated earlier. The device will only draw what it requires from the power pack. The power pack isn’t ‘forcing’ the current down the neck of the laptop.

Can I use a 19V charger for a 20V laptop?

Yes: technically it can be used, but you need a higher amount of power (watt). if the adapter is 19V 6A, it might start the PC but you will have strange side effects.

Will a 19v charger work on a 19.5 V laptop?

It’ll be fine. Laptops have internal high-precision voltage regulators which convert down from the very roughly-regulated voltage supplied by the charger to the exact voltages they need for different things so half a volt won’t make any difference.

Can I use 12V adapter for 19V?

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.

Can I use a 90 watt charger on a 45 watt laptop?

Yes you can use a 90 watt charger on a 45 watt laptop as long as everything like the connection and stuff matches . Those universal chargers you see in stores that have different tips for many different laptop brands and models are essentially just that . The laptop has limits to how much charge the battery will accept at any time .

What is the difference between a 5A and 8A power adapter?

For example, your laptop may be rated for an 8A draw, but in reality, it only draws around 5A. Conversely, an adapter may be rated at 5A, but can withstand currents up to 8A. Also, some adapters and devices will have voltage and current switching or detecting features that will adjust the output/draw depending on what’s needed.

Can I use the 65 watt adapter to charge my laptop?

So, in short, buy the original adapter (90w), and till that arrives, you can use the 65w adapter, but DO NOT USE THE LAPTOP while charging. After it charges fully, unplug the adapter, and then only use it. Hope this helps!
