65W vs. 100W Laptop Power Banks: Which Should You Choose?

By Robert Peterson

Choose 65W for everyday laptop work and phone charging. Choose 100W when your laptop can use more power, especially during demanding work. Either can charge USB-C MacBook Air and MacBook Pro models, but the speed will vary.

Is 65W enough for a MacBook Pro?

Yes, a USB-C charging MacBook Pro can charge from 65W. A 14-inch or 16-inch model may charge more slowly than with its usual wall charger, particularly while editing video or gaming. Let it sleep if the battery is dropping while plugged in.

When is 100W worth choosing?

Choose 100W if you want more available power for a compatible laptop, or if 65W struggles to keep up with your normal workload. It does not automatically make every laptop charge faster: a laptop that accepts less power will not use the extra.

Does 100W mean more battery life?

No. The 20,000mAh 65W and 20,000mAh 100W TSBar models store the same amount of battery power. The main difference is how quickly they can supply it. A 30,000mAh model gives you more stored power, but its charging speed depends on its port.

Which cable do I need?

Use a USB-C cable rated for 100W or 240W for the full output from either model. A 60W cable can limit charging below 65W. Plug the laptop into the main USB-C port and unplug other devices when you want the most power available for it.

Can I also use it for phones and tablets?

Yes. Use the appropriate USB-C, Lightning or other charging cable. A higher-powered laptop bank does not force extra power into your phone. With more than one device connected, the available power is shared.
