can i use phone charger to charge laptop

[McKate]

Of course! That's a great and very practical question.

Based on the information, the answer is generally yes, but with some important things to keep in mind. The key factor is whether your laptop charges using a USB-C port. If it does, you can often use a USB-C phone charger to give it some juice.

However, the main difference between a phone charger and a laptop charger is the power output, measured in watts (W). Your laptop requires a lot more power than your phone, so its original charger will have a much higher wattage. A standard phone charger might only offer 15-30W, while a laptop often needs 45W, 65W, or even more.

If you plug a lower-wattage phone charger into your laptop, a few things might happen. It might charge very, very slowly. In some cases, it may only be able to charge the laptop when it's turned off or asleep. If you're using the laptop while it's plugged into the phone charger, you might even see the battery level continue to drop, just at a slower rate than usual. It's a handy trick in an emergency, but it's not a perfect replacement for your laptop's dedicated charger.
