Can I charge my laptop with my phone?
While it’s technically possible to charge a laptop with a phone, there are some limitations and considerations to keep in mind. Most modern smartphones have a USB-C or USB-OTG (On-The-Go) port that can be used to output power, but the amount of power they can deliver is typically limited to around 5-10 watts. This is much lower than the 60-90 watts required by most laptops, so charging your laptop with your phone will likely be slow and may not be practical for everyday use.
That being said, if you’re in a pinch and need to top off your laptop’s battery, using your phone as a power source might be a viable option. You’ll need a USB-C to USB-C cable or a USB-OTG adapter to connect your phone to your laptop, and you should also make sure that your phone is fully charged and has enough power to spare. It’s also worth noting that not all phones support USB-OTG or power output, so you’ll need to check your phone’s specifications before attempting to charge your laptop with it.
What kind of cable do I need to charge my laptop with my phone?
To charge your laptop with your phone, you’ll need a cable that can carry power from your phone to your laptop. The type of cable you need will depend on the types of ports on your phone and laptop. If your phone has a USB-C port and your laptop also has a USB-C port, you can use a USB-C to USB-C cable. If your phone has a USB-C port but your laptop has a traditional USB-A port, you’ll need a USB-C to USB-A cable or a USB-C to USB-A adapter.
It’s also important to make sure that the cable you use is capable of carrying power. Not all USB cables are created equal, and some may only be designed for data transfer. Look for a cable that is specifically designed for power delivery and has a high enough power rating to support your laptop’s charging needs. A cable with a power rating of at least 60 watts is recommended, but you may need a higher-rated cable depending on your laptop’s specifications.

Another option is to use a solar charger, which can be used to charge your laptop using sunlight.
Other options include using a car charger, which can be used to charge your laptop while you’re driving, or a wall charger, which can be used to charge your laptop from a wall outlet. You can also consider using a laptop with a longer-lasting battery or one that supports faster charging, which can help minimize the need for on-the-go charging.
Is it worth buying a phone with a high power output for charging my laptop?
If you plan on using your phone to charge your laptop regularly, it may be worth considering a phone with a high power output. Some phones, such as those with Qualcomm’s QuickCharge technology, can deliver up to 18 watts of power, which is significantly higher than the 5-10 watts delivered by most smartphones.
However, it’s worth noting that even with a phone that has a high power output, charging your laptop with your phone will still be slower than using a dedicated wall charger or power bank. Additionally, phones with high power output may be more expensive than those with lower power output, so you’ll need to weigh the benefits against the cost. If you only need to charge your laptop in emergency situations, a phone with a lower power output may still be sufficient.
