How do I know my laptop charger wattage?
Read the original adapter’s label. It shows output like “19.5V 3.34A” — multiply volts by amps to get watts (here ~65W). Buy the same wattage or higher, never lower, and keep the same voltage and pin type.
Laptop Chargers & Adapters for HP, Dell, Lenovo, Asus & Acer
A laptop that charges only at a certain cable angle, shows “plugged in, not charging”, or does not power on at all often has a failed charger rather than a failed battery. Replacing the adapter is the cheapest first fix, but it must match three things: wattage (W), pin/connector type, and output voltage.
LapKart stocks barrel-pin and USB-C Power Delivery (PD) chargers for HP, Dell, Lenovo, Asus and Acer. Using a lower-wattage charger can make the laptop charge slowly or not at all under load, and a wrong pin size simply will not fit, so match the original adapter’s rating printed on its label.
Each charger lists wattage, connector and output up front, with warranty and COD at checkout, and Tamil Nadu delivery from Rs 50 (free over Rs 2,000).

Frequently asked questions
Can I use a higher-wattage charger safely?
Yes, if the voltage and connector match. A 90W charger on a laptop that came with 65W is safe — the laptop only draws what it needs. A lower-wattage charger is the one to avoid.
What is the difference between barrel-pin and Type-C chargers?
Older laptops use a round barrel pin in a specific diameter. Newer thin laptops charge over USB-C Power Delivery. They are not interchangeable; check which port your laptop uses and the required PD wattage for Type-C.
My laptop says “plugged in, not charging” — is it the charger?
Often yes, especially if the laptop runs only while plugged in or charges intermittently. It can also be the battery or DC jack. See our diagnosis guide and test with a known-good charger of the correct rating.
Do replacement chargers include the power cable?
Cable inclusion is noted on each product page. Warranty terms and COD eligibility are shown there too.
