FAQ

Q: How Much Capacity Is Good for a Laptop Power Bank?

If you want to recharge your laptop fully at least once, you need a power bank with enough capacity. Most regular-sized smartphone power banks only have 10,000mAh, which is usually not enough for a computer.

It's wise to get a least a 20,000mAh power bank to ensure you can recharge your PC fully at least once. If you don't need to fly with your power bank, you can get a larger 40,000mAh one, allowing you to recharge most laptops at least twice over.

Q: Can I Charge a 65W Laptop With a 45W Power Bank?

Yes, you can. As long as the power bank can deliver the required voltage and has a compatible connector or cable, you can recharge a higher-watt-capacity laptop with a lower-watt-output power bank via USB-C.

However, you should know that this will cause your laptop to recharge much more slowly, so don't expect it to fill as quickly when the computer is plugged into its charging brick or a higher-watt-output power bank.

Q: Is Charging a Laptop With a Power Bank Overnight Okay?

Yes, with most modern laptops and power banks, the battery will stop charging as soon as it hits 100%.
