What Power Bank Works for Both Phones and Laptops
You may have experienced this before: you’re out with your laptop, the battery is running low, and the power bank in your bag can only charge your phone. That leaves you searching for a wall outlet.
Today, many power banks are designed to charge both smartphones and USB-C laptops, making them useful for work, study, and travel.
This blog explains what to look for when choosing a power bank for both your phone and laptop.
Three Things to Check Before You Buy
Power Output
Laptops generally require more charging power than smartphones, so the output of a power bank is important.
For many lightweight USB-C laptops, including some Ultrabooks and MacBook Air models, a 45W power bank can provide enough power for everyday charging. Higher-performance laptops may require a 65W or 100W power bank, and some laptops may not support USB-C charging.
For users who mainly carry a phone and a lightweight USB-C laptop, a 45W power bank can be a practical everyday choice. Before buying a laptop power bank, always check your laptop’s charging requirements.
Battery Capacity and Wh Rating
Battery capacity is another important factor when choosing a power bank for a laptop.
The capacity printed on a power bank refers to its internal battery capacity. Some energy is lost during voltage conversion and charging, so the actual usable capacity will be lower.
A 20,000mAh power bank stores more energy than a smaller 5,000mAh or 10,000mAh power bank, making it more practical when you need to charge both a phone and a laptop.
You can also check the Wh (watt-hour) rating. A higher Wh generally means the power bank stores more energy and can provide more backup power for your laptop.
Compatible Ports and Protocols
When choosing a power bank for a modern laptop, USB-C support is important.
A laptop power bank should include a USB-C output, and ideally the USB-C port should support bidirectional charging. This allows the same power bank port to charge your devices and recharge the power bank itself.
For USB-C laptop charging, PD (Power Delivery) support is essential. Without it, your laptop may charge very slowly or may not charge at all. A PD power bank can support higher charging power for compatible USB-C devices.

Conclusion
Choosing the right power bank for both phones and laptops mainly comes down to three things: power output, battery capacity and Wh rating, and USB-C PD support.
For many everyday users, a power bank with 45W output and 20,000mAh capacity offers a practical balance between portability and charging capability.
