Quick Answer: Can A Charger Be Too Powerful?

Can I use a 65w charger instead of 45w HP?

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..

Can you damage your phone by using the wrong charger?

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 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.

Is it OK to use a higher amp charger?

Amperage. … Your computer will use more power, in the form of higher amperage draw, when it’s working hard than when it’s not. (Voltage remains the same regardless.) Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous supply, you’ll be fine.

Can you use a 90w charger on a 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 20v charger on a 19v laptop?

“if you use a 20v charger on a 19v rated thing, you will be “forcing” an extra 0.235A (V=IZ, Z is the appliance’s impedance) into the device in addition to the 4.47A.” This does not make sense.

How many watts is a fast charger?

Standard chargers that come with iPhones and older Android phones carry 1 amp of current and put out 5 watts of power. New rapid chargers with technology such as Quick Charge support 2 amps and 12 watts or more, potentially charging your phone up to four times faster.

Can I use a 60w charger instead of 45w?

You can always use an adapter that has a higher power rating than is required as long as the voltage rating is the same. … Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties.

Does higher wattage charge faster?

But to reiterate the point from Wired’s article, it’s a myth that you will reduce phone battery life or blow up your phone by charging at a higher wattage than its standard charger offers. Newer, higher wattage chargers simply speed up the charging process.

Is Fast charging bad?

The lithium-ion technology that goes into batteries powering modern Android smartphones allows for fast recharging. Consumers who are interested in a fast-charging solution sometimes worry that a faster transfer of electricity could damage the phone’s battery. But in fact, you have nothing to worry about.

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?

Voltage: When trying to match a supply to a device, you need to get the voltage right… if the supply voltage is too high, then it will damage your device. … Current: When looking at current, you need to ensure that the Amps rating is higher than the device needs as it will only use as much electricity as it needs.

Is 12w a fast charger?

The 12W charger and all of the Apple USB-C chargers deliver nearly identical performance, charging the phone to 85 percent in about an hour and 20 minutes. That’s an hour faster than the in-box charger.

What is the most powerful USB charger?

The Anker 36W charger occupies only a single wall outlet when plugged in. Anker’s 36W 4-Port USB Wall Charger is the best multiport USB charger for most people. It’s the most powerful charger that plugs directly into a wall outlet, letting you fast-charge up to three full-size iPads at once or four at a slower rate.

Is 2.4 A fast charging?

Most phones and other devices are capable of handling 5V/2.4A. For fast charging, you’re looking at something that bumps the voltage up 5V, 9V, 12V, and beyond, or increases amperage to 3A and above. Keep in mind, your device will only take in as much power as its charging circuit is designed for.

Do milliamps matter?

The milliamp rating of a power supply is a measure of how much it can supply. The milliamp rating of a pedal is how much it uses. All that matters is supply exceeds demand. The 230 vs 220V rating probably means nothing.

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.

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 you use a 90w charger on a 65w?

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.

What happens if you use a higher wattage 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.

Does the wattage of a charger matter?

Watts are supplied “on demand” to the battery that’s being charged, so even if you’re over the device’s limit, it doesn’t cause problems. … A laptop will typically call for watts between 45 and 100. Not all chargers will list the watts, but if the amps and voltage match, you’re usually in the clear.
