Can I use a 45w charger instead of 60w?
Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties.
You can always use an adapter that has a higher power rating than is required as long as the voltage rating is the same..
Is it bad to use a higher watt charger?
This means that you can quite safely use a charger with a higher wattage (or amps) rating as the laptop will only ever draw the amount of power required at the time. … A 30W or a 45W charger can not supply sufficient power for your laptops needs which means you could damage the laptop and/or the charger.
Can I use 85w charger instead of 60w?
Yes, with a caveat. The 85W adapter can be used inconsequentially with both models. It will provide ample power to both the MacBook Pro and MacBook, and will not damage the latter despite a higher-than-necessary wattage. … Note, however, that the 85W adapter will not charge a MacBook any faster than the 60W adapter.
Can the wrong charger ruin your laptop?
Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won’t damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.
Can I use a 90 watt charger on a 65 watt 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. But, and this is a big but, you cannot use a 19 Volt ac adapter on an 18.5 Volt-laptop.
Do I need a 60w or 85w charger?
You can charge using a higher wattage than is permitted, but you should not use a lower wattage. For instance, the MacBook Pro 13 inch uses a 60W MagSafe, but you can use an 85W MagSafe to charge or power it (although it will not charge any faster).
Can I use a 90 watt charger on a 130 watt laptop?
Generally the answer is yes, but it won’t supply enough power to charge the battery while you’re using your laptop. This will probably invalidate your warranty and could cause damage to your laptop, but the changes for that are small.
Can I use a 19.5 V charger on a 18.5 V laptop?
Your laptop takes 18.5V and the new charger is 19.5V. … Generally speaking, a 5% variance in voltage up or down is acceptable when in computer power supplies. Plugging in an adapter with more than a 5% voltage difference and you are running the risk of damaging or destroying the laptop.
Do all HP Chargers work for all HP laptops?
In most cases, the current line of HP computers will share the same AC adapter (charger). There are a few exceptions to this rule but generally HP laptops will share chargers with other HP laptops that were introduced in the same time frame.
Can I use a 90w charger instead of 45w?
If the output voltage is the same, you can use a 90W charger on a 45W laptop BUT cannot use a 45W charger on a 90W laptop. On the condition of same voltage, laptops and other devices will never overpowered. The amps you saw is the maximum one adapter is capable of, not the rated current.
Can I use a 90 watt charger on a 120 watt laptop?
When the current is less than the rated value, the output voltage is higher. In the case of Laptops the regulation is probably in the Laptop and if that is the case then no problem using the larger (120 Watt) as the current (output power) will be the same for either the 90, or 120 Watt brick.
Can a charger be too powerful?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
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.
Can I use a 45w charger instead of 65w?
If the voltages match, the 45W should just charge a bit slower than the 65W. I would refrain from running anything heavy though, as it may be more load than the adapter can handle and it will drain the battery as well.
Can a 65w charger for 45w laptop?
Yes. Wattage is a measurement of how much power a supply CAN generate, or how much your device DOES consume. The wattage of your power supply is a rating of the maximum power that can be drawn down from it; if your computer requires 45w but your supply can provide 65w, you will be fine.
What happens if amps are too high?
A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm.
Does higher wattage charge faster?
Use a wall charger In general, the higher the device’s wattage, the faster it can deliver a charge to your iPhone. The wall charger that comes with your iPhone is relatively anemic, rated at 5 watts.
