• Before ordering this replacement Dell Vostro A840 Laptop Car Adapter, You MUST check your laptop's input voltage and your original adapter's output voltage. Laptops with 18V-20V input voltage can use our adapter which has 19V output voltage; Laptops with 15V-17V input voltage can use our adapter which has 16V output voltage; Remember : never exceed +/-1V tolerance. Using wrong output voltage adatper will damage your laptop computer.


• You can calculate your original Dell Vostro A840 Laptop Car Adapter's output Wattage [W] by multiplying the Ouput Voltage [V] by output current [Amps] i.e 19V X 4.74A = 90 Watts. You can choose a replacement Laptop Car Adapter which has higher Amps than your original Laptop Car Adapter's, but you can not choose an Laptop Car Adapter which has lower Amps than your original Laptop Car Adapter's because it can not provide sufficient power to your Dell Vostro A840 laptop. Adapters with higher Amps will not damage your laptop computer. The adapter's output current (Amps) and output power (watts) are maximum load ratings. Computers only draw as many amperes or watts as they need.


• Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, Laptop Car Adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet(or cigar lighter). 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 wrong tip in your laptop
