Big currents are required for faster battery charging, but unfortunately this requirement increases the weight of the power supply.

Can I use 19V 3.42 A?
Q: Can we use 19V 3.42A charger in other Laptop which supports 19V 4.74A charger ? 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.
Is it OK to use a power supply with higher amps?
Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous, you’ll be fine.
Can I charge my laptop with a higher amp charger?
Yes, Your laptop has been designed to draw up to a certain amount of power when running at full power.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.
How many watts is 19.5 VDC?
19.5V * 2.5A = 48.75W.
Can I use 65W charger for my phone?
Yes, the phone supports USB-PD, which is what the laptop charger will be using to charge. Although the charger can provide 65W, it will only deliver a maximum of 27W to the phone, as that’s what the phone will communicate is its maximum.
Will a 3 amp charger hurt my phone?
Nothing, because nothing is there to ask for the amperage needed to produce that kind of power. It goes to a step down converter usually to 5 volts at 2 amps. Fast charging is 9 volts at about 1.7 amps. I would not recommend plugging your phone into a standard home 110 outlet.
Is it OK to charge phone with higher amp?
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.
What are amps vs volts?
Amps are simply the amount of electricity used by the item. Volts are the measure of the force of the electric. Amps multiplied by volts gives you the total wattage (workload). Understanding how the three terms relate helps with understanding the electrical requirements of an item.
Does more amps mean faster charging?
“Ultimately, it’s really the amperage that determines how fast a charger will supply power to your device. If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts (or whatever voltage the device you’re trying to charge is specced at).”
Will too little amperage hurt a device?
you can’t really damage a device with amps, as a device itself consumes amps it needs to power function(s) it performs, unless it is damaged already, in which case damage will be done to the power supply, unless the output of the power supply is protected.
Does higher amp damage battery?
The answer is yes to both. Even batteries that charge in a couple of hours or so, have charge current 1/2 the amp hour capacity. That 1000 milliamp hour battery would be charged at 500 milliamps. Charging a 1,000 milliamp hour battery at 1 amp or more would likely damage or destroy it.
Can I use a 65 watt charger on a 45 watt laptop?
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 65 watt charger on a 90 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.
Can I use 65W charger instead of 30w?
Yes you can but, it will charge at the same speed at which it charges with your out of the box charger at 30w and it will not damage or degrade your battery.
How much is 9 volts in watts?
Equivalent Volts and Watts Measurements
| Voltage | Power | Current |
|---|---|---|
| 9 Volts | 9 Watts | 1 Amps |
| 9 Volts | 18 Watts | 2 Amps |
| 9 Volts | 27 Watts | 3 Amps |
| 9 Volts | 36 Watts | 4 Amps |
How many volts is 1000 watts?
Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.
How many watts does a TV use?
Key findings: Modern TVs use, on average, 58.6 watts when in On mode and 1.3 watts in standby mode. The power consumption of modern TVs ranges from 10W to 117W (0.5W to 3W on standby). On average, TVs consume 106.9 kWh of electricity per year, costing $16.04 annually to run in the US.
