Your phone and laptop both charge with USB-C, so can you use your phone charger to power up your laptop? The answer depends on several factors.

In short, getting your smartphone or tablet to charge quickly is something of an arcane art. If you have an iPhone or iPad, be sure to charge it with your Apple PC or use the Apple-provided wall wart.

While you can't use just any laptop charger with any laptop, you may be able to use a simple USB-C charger, like the one you use for your phone, instead.

Using your phone while charging can rapidly increase the temperature, putting strain on your battery, screen and processor. Charging rules are essential when it comes to your computer, too.
