How to Charge a Cell Phone Using Laptops
Some cell phone batteries can last 10 or more hours without charging, while others are less prolific and need charging more often. When you are away from your home or office, it can be difficult to keep your cell phone continuously charged. But luckily there is a solution to the problem of charging if you have a portable laptop handy while you're out and about, even if you do not have a traveling power adapter.
Things You'll Need
- USB cable for your phone
Purchase a USB cable from your cell phone provider's store or online that is compatible with your phone model. This cord comes standard with some new phones, like PDA devices.
Insert the USB cable into your phone and then into the USB slot on your laptop.
Plug your laptop into a power outlet using its power charger.
Start up the computer and log in (if required). Once the computer is active, it begins to charge your cell phone phone. So long as you have the cell phone solidly connected to your computer with the USB cable, while the laptop is in use and plugged into the outlet, it will stay charged.
Tips & Warnings
- If you want to save energy on your cell phone while you're on the road, turn off unnecessary programs that are running in the background (like navigation software and games) and turn off the vibrate option.
