What if you use adapter with more voltage for lap top?
Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. If it doesn’t, it may run hotter than normal, which can shorten the device’s life or cause immediate damage.
Can I use an adapter with higher voltage?
The short answer is yes you can use a laptop charger with a higher wattage, however, there are some caveats. The wattage rating of a laptop charger is a maximum rating which means that the charger is capable of providing power up to the output wattage rating and or course anything in between.
Can you use 15V adapter 12V device?
Can I use a 15v plug to a 12v device receptor? In the case of cooling fans the answer is generally yes. Most cooling fans accept a variable DC voltage of between 6V to 23V. Anything else I would say “No.” Wall bricks are cheap at around $6 for a cheapo from Fry’s, and will step down 110V AC to 12V DC in a snap.
Can I use 12V adapter for 19V?
A 12V adapter is unlikely to damage the components, but it is possible depending on the design and that’s why I mentioned it. The likelihood is probably vey tiny though so you can probably ignore that bit.
How to deal with a DC adapter with irregular voltage?
The solution in that case is to increase the capacitor size. If the DC output from the adapter is higher than what is needed in the circuit, another option that will help stabilise the output is to regulate the voltage down as required, after the capacitor, using a standard voltage regulator.

How much voltage do you need for a DC adapter?
In most applications these supplies are followed with a linear regulator to provide a stable voltage. You still need a minimum load and some filtering capacitors. 4000 µF is excessive and possibly dangerous. Typical capacitors are in the 1-100 µF range. The size and type of capacitor is dependent on the linear regulator.
What’s the difference between DC and DC power adapters?
Likewise, each electronic device is specifically designed to accept a certain DC input. The key is to match the DC output of the adapter to the DC input of your device. Determining the outputs and inputs of your adapters and devices is the hard part. Power adapters are a bit like canned food.
Is it okay to use a power supply that provides slightly more voltage?
This doesn’t mean your device will consume 3.42 A when its powered with this adapter; it is only an indication of the maximum current that can be drawn through the adapter by any device that it is connected to, above which the adapter gets damaged. Any device will only draw as much current as it needs, so long as its power source can supply it.
