All new laptops come with AC adapters. Adapters are used for charging laptop batteries and also used to supply power directly. There are occasions which we require to buy an AC adapter. Most laptop users travel, for they travel to Europe or US they require AC adapters that take 100-240 voltage input and output 16 voltage or 19 voltage.

Let us present 3 easy steps to pick the right laptop chargers.

1. Finding the right “tips” – Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, laptop AC adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called “TIP” which you will plug this tip into the “DC IN” in your laptop.

Your laptop won’t work on the wrong tip. You can only use the ” matching Tips”

Warning: DO NOT try to force it in.


2. Finding the right “output voltage” – Different laptops were designed to consume power varied by equipments such as CD-Rom, LCD size, CPU maker and CPU speed. You require to use the “matching voltage” . Only use the laptop AC adapters output the matching voltage of your laptops. You can easily locate your laptop voltage. Mostly, voltage is printed on your laptops. You also can check your laptop manual.


3. Find the right “input voltage” – for they users who will travel abroad especially to Europe and Asia. You would need laptop AC adapters that compatible with 220-240 voltage also. So it would be wise…and yes…you are!!…. Always look for AC adapters accept 100~240 voltages. 100~240 voltages AC adapters will go with you worldwide. You do not need to carry 2 adapters anymore!!!

That’s easy!!! You now know the basic knowledge to find your laptop power adapters.

AC Adapter Tips

An AC adapter allows a laptop computer to be plugged into a standard wall outlet. It converts the “AC” (or “alternating current”) of a wall outlet to “DC” (or “direct current”) so the laptop can draw power safely while charging the battery. Usually, an AC adapter is built to last for years, but sometimes it does not last as long as planned. When caring for or replacing a faulty AC adapter, there are a few things to keep in mind in order to maximize its usefulness and compatibility.

AC Adapter Compatability

Not all AC adapters are created equal. Some will have differing input and output voltages which makes choosing the correct one frustrating. If you are replacing a laptop’s adapter, always check its specifications to determine the power requirements. Also, laptop computers have different sized DC adapter plugs, so make sure that the adapter that you buy will fit. Many universal AC adapters come with interchangeable plugs to prevent this problem.

Problems That May Arise

While it is normal for an AC adapter to get warm to the touch while plugged in, any other signs of trouble may require immediate action. If your adapter is making a high pitch noise, replace it. If your adapter stops working completely, it may be a sign of a bad transformer or a wiring issue. If you fancy yourself an amateur repairman, keep in mind that it is generally a bad idea to open up the AC adapter for any reason. In addition to being notoriously difficult to open (without a hacksaw), the internal components can deliver dangerously high voltage levels to inexperienced repairmen.

Tips Packs for AC Laptop Adapter

This solution is Ideal for clone laptops like which are imported from Taiwan and rebadged by companies like Advent (PC World), AJP, Evesham, E-machines, Elonex, Hi-grade, iFriend, Rock and many others or for laptops where the size on the DC power plug is difficult to determine. With this method you just need to use our AC adapter selector which will give you the “best fit” option with the correct voltage and suitable current output, then the tip packs supplied should fit your laptop, if it does not we will give you your money back.

IMPORTANT: Your laptops DC power plug must be round (male or female type) like the example above here. If your laptops DC power plug has two or more pins in the center or is any other shape than the round barrel type shown here then these universal AC adapters & tip packs will not work with your laptop. Please refer to the tip list here to see any of those may fit your laptop.

Let our system select the correct AC adapter & Tip pack

You can use our adapter selector/calculator the tell you the correct combination of AC adapter and tip pack, all we need to do this is enter the DC input voltage and the current in to the calculator here below.

To find out the voltage & current, turn your laptop over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below. The voltage figure will have a “V” after the number i.e 19V and the current will have a “A” i.e 3.15A, if the is no current rating please email us for assistance. You can also find these shown in a similar fashion on the original AC adapter if you have it. In the examples below the voltage & current has been marked with a red ring.
