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..
Is it OK to use a different laptop charger?
The short answer is; No. You should never intentionally use another laptop’s charger on your laptop. It doesn’t matter if you’re in a pinch or if your battery is about to die. Plugging a different charger that isn’t meant for your specific model will not lead to anything good.
How do I know if a charger is compatible with my laptop?
Look for the amperage and the voltage required. Look up the model number online to find if there are compatible adapters available. The voltage and amperage of the adapter need to match the requirements of the laptop. Compare the connector type of the laptop adapter to any available adapters found online.
Can I use a 60w charger instead of 45w?
here’s the definitive answer: YES, you can use a higher rated power adapter with your MBA (or whatever) with no ill effect. … in the reverse case, if you use too low a wattage adapter (e.g. 45W one on a MB Pro), there won’t be enough current to charge the battery, although you can run it off AC power while plugged in.
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 19v charger on a 19.5 V laptop?
Voltage: 19.5V and 19V is a relatively small voltage difference. It is most probably safe to use as long as: The current of the charger is the same or higher than that of the laptop. … The output power (Amps * Volts) of the original and the new charger differs in 0.6 Watts, the 19.5V charger having more output power.
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.
Can I use 65w charger instead of 90w?
A 65W adapter may work but probably won’t charge as fast as the original and will probably run hotter than the original.
Can you use a 65w charger instead of 45w?
As long as it is the same voltage and connector type you can use a higher watt adapter. It will charge the battery a bit faster but other than and the size of the brick you will see no difference. The laptop will only draw the current it needs while running.
Can I use a 90 watt charger on a 120 watt laptop?
You should not use a 90 Watt brick if you need a 120 Watt brick. While I talked about charging currents, The max output requirement is based on Charging current required by a depleted battery pak + Operating current required by the laptop under full load.
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.
What is the difference between 45w and 65w charger?
You can definitely use the 65W charger. The brick will be a little larger and heavier and it will charge your battery a bit faster. The plug and the voltage are the same so it works with your laptop fine.
Can I use a 130w adapter on a 65w laptop?
The laptop will only draw the current it needs so you will not fry anything. You can use an adapter with more amps and the same voltage and the same physical connection without any problems. It will even charge the battery faster.
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 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 the wrong charger ruin your phone?
Generally speaking the wrong charger to the wrong phone can cause damage. … Thankfully, the advent of USB changed all that and has provided an easy, standardized platform for charging devices. All USB cords carry the same 5V, regardless of if it’s got a 30-pin head or a microUSB plug, whether it’s first-party or third.
Can I use a 45w charger instead of 90w?
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 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.
