The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following, The adapter output V matches the rated input V of the device. The adapter output is greater or equal to the devices rated mAh or A.
How do I match my power adapter to device?
The right AC adapter for your device is one with matching electrical ratings. The device’s input voltage and current must match the adapter’s output voltage and current. Check the device’s product label or user manual to see its rated voltage and current.
How do you know if a power cord is compatible?
Any AC adapter is considered compatible with any device if it has all the following traits:
- The voltage of the adapter has to be identical.
- The amperage (amps) of the adapter has to be equal or greater than the device.
- The polarity of the adapter has to be identical.
How do I choose the right power cord?
When selecting a power cable for your unique application, its intended use should always be top of mind. Other key considerations include end finishing, cord set put-up, insulation material, conduction material, wire gauge, voltage, temperature range, cord shielding, and finishing requirements.
How do I match my power supply?
The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following, The adapter output V matches the rated input V of the device. The adapter output is greater or equal to the devices rated mAh or A.
Are power cords interchangeable?
As Bruce stated, the power cords are universal. Even some monitors (generally older CRT models with detachable cords) and some printers use the same type of cords. Power cords for desktop computers are the same. There are regional differences due to the configuration of the plugs around the world, but that is it.
Are laptop power cords interchangeable?
Laptops can share power cords so long as the adapter’s wattage and connector tip is correct and compatible for each laptop you wish to use it with.
How do I know if my power adapter is working without a multimeter?
Without it, there is nothing you can do. So first step is to plug the supply in and connect probes of the meter to the inner and outer connections of the supply. You should get around 19 V, if I’m reading the info on the site correctly. If you get good voltage, then it’s very likely that it’s working correctly.
Can I use 500mA instead of 300mA?
Since 300mA is less than 500mA you should be fine. It will work, as long as the voltage is correct. The power adapter’s nominal power is 500mA so it will work at a lower cycle (60%) than its full power. It will work just fine.
Will too much amperage hurt a device?
As long as the correct voltage is used, a device will draw only the amperage it needs, meaning there will not be “too many amps”. If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn and the device can be damaged.
Can I use a 1A charger for a 2A device?
It is perfectly safe to plug a device that draws 1A into the 2A port and vice versa. Amperes are a measure of current capacity.
How can I tell what power supply I have without opening my computer?
There are many watt meters available in the market by which you can check your power supply wattage without opening your computer. Just plug your wattmeter direct to your ac point then plugin your power supply to the wattmeter, now start your computer and you can see your wattage drawn by your computer power supply.
Can I use 18V adapter for 12V?
18V would be risky, I would not try to plug a 12V device into an 18V battery. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter. I use car-plug type adapters for all my 12v equipment because they have fuses in them.
Can I use 12V 3A for 12V 2a?
Yes, you can use. The voltage rating of the device should not decrease but for current it will work as it means the device need 1.5A current to work and our adapter is capable of providing till 3A current.
What is A universal power cord?
OverviewA universal power cord is used to transfer power between different devices. They are often used in place of lost or damaged power cord, as they’re a cheaper option in comparison to buying a replacement power cord from a device manufacturer.
Can I use any AC power cord?
Ac voltage is important but usually AC devices only draw the amperage as neeeded so as long as there are sufficent amp supplied, the device should be ok.
What is A universal power supply?
Universal input means the power source input range is within AC 85 ~ 264 Volt and capable of operating at 50 and 60 Hz. These power supplies can be used anywhere in the world without adjusting a select switch for the input power.
Can I charge laptop with different charger?
No. Though, you can use a charger of the same voltage (volts, V,) and the equal or higher current (Amps, A) than required by your laptop. For example 18V 3A (54Wats) charger can replace original charger 18V 2A (36Watts). Higher voltage charger will damage the laptop.
Can you splice a laptop power cord?
You can repair the cable by cutting out the chewed section. Solder and shrink wrap the middle cable first then solder and shrink wrap the outer cable next.+1 for suggesting a solder fix and not just a twist-and-electrical-tape fix.
How do I fix my universal plug?

What does the EU plug look like?
The Type C plug (also called the Europlug) has two round pins. The pins are 4 to 4.8 mm wide with centers that are spaced 19 mm apart; the plug fits any socket that conforms to these dimensions. It also fits into Type E, F, J, K or N sockets that often replace the Type C socket.
