This is due to the fact that the Li-ion needs to be charged while the computer is running. The charger will input a higher voltage to charge the battery while the 19v is pushed through a buck converter on the motherboard that outputs a regulated 12v to power the motherboard. This is neccessary to efficiently charge you laptop battery.

How much power is used by a 35w bulb with 12v supply vs 110v supply?

it also depends on what meter you have, is it a KWH METER or a AH METER. IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)

Where is the gp sorensen mr78 relay on the 1991 lumina apv?

I went searching in my APV for this relay because an Autozone clerk sold it to me as a fix for a voltage fluctuation. While driving and monitoring with a ScanTool, the system goes from about 14V to below 12V, and the headlights dim, the power windows can only creep, the cruise dies, and the heat gauge maxes. There seems to be no pattern, or relationship to the open/close loop, radiator fan, coolant temp, even engine speed. The drop comes and goes, maybe every 10 to 20 minutes. After taking apart most of the console and searching under the hood, I found the relay behind the air compressor control panel behind the back seat. I had disconnected the relay years ago because during suspension repair, I had abandoned the load levelers, and the air compressor kept pumping until the relay was disconnected. Today I reconnected it and snipped 2 wires at the actual pump to kill the compressor, and replaced the relay. And yet, the up/down voltage continues. What the heck is going on? The "HATCH AJAR" indicator also went off after years of staying on... but came back on. And where is the sender for this warning light??? Thank goodness the APV is just a boat tow vehicle, and I also own a Prius.


How fast can a jetta go?

As fast as you can go before you get pulled over....around 135 mph. Depending upon the model of jetta and the year in which it was built. Mk3 jettas with a 12v Vr6 was speed limited at 135mph. Mk4 jettas are speed limited to 135mph across the board. (all models) Jettas that have the vr6 or 1.8T can go faster than 135mph with the speed limiter removed. Some Gli's seem to have increased limiters . The 2004 Gli with 1.8T has been known to achieve 150mph with minimal modifications and no ECU flashing. 2005 mk5 Gti and GLi and later are speed limited to 127 mph. 2009 models once again are limited to 135mph & 2010 to 127mph. **note the pattern during the platform run, the last year before a body style change is always slightly faster than the previous) The VW way!!

What will happen if use a 12v 500ma instead of 12v 300ma?

Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.


What will happen if use a 12v 400ma instead of 12v 500ma?

i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)


Can you use 12v 600ma instead of 12v 500ma?

Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.


How does a 12v to 115v converter work?

A 12v to 115v converter, like an inverter, works by converting direct current (DC) from a 12v source (such as a car battery) to alternating current (AC) at 115v. This is typically achieved through electronic circuitry that switches the DC input to create an AC output, allowing you to power AC devices (such as laptops or small appliances) from a DC power source.


How you convert a power supply into 12v DC?

DC 12V power supply can convert 110/220V AC power source to 12V DC.

Is there a power supply for laptops on an airplane?

A standard airline power jack provides 12V power just like the cigarette lighter in your car. If you have a DC (car) power supply for your computer already, there are adapters available which convert the cigarette-lighter plug to the smaller airline plug.


Can you use a 12v-0.6a 7.2va adaptor instead of a 12v 1.5a adaptor?

No, you cannot use a 12V 0.6A (7.2W) adapter instead of a 12V 1.5A adapter. The 0.6A adapter provides insufficient current for devices that require 1.5A, potentially leading to underperformance or damage to the device due to inadequate power supply. Always match the voltage and ensure the current rating of the adapter meets or exceeds the device's requirements.

Can I use a 12v 7ah battery instead of a 12v 12ah battery?

Yes, you can use a 12V 7Ah battery instead of a 12V 12Ah battery, but there are important considerations. The 7Ah battery will provide a shorter runtime and may not meet the power demands of your device if it requires consistent output. Additionally, ensure the discharge rate is compatible with your application to avoid damaging the battery. If your usage exceeds the 7Ah capacity, it may lead to quicker depletion and potential over-discharge.
