What to Compare Before Buying
- Laptop size: This model is stated to fit up to 15.6 inch laptops, so compare that with your device size.
- Overall dimensions: The stated 17" x 12.3" x 7.6" size helps you judge storage space and how much room it will take up.
- Charging setup: The USB port works with a connected power bank, which is not included, so check whether you already have one.
- Carrying style: Padded shoulder straps, a handle and a luggage strap are included in the described design, so compare that with how you plan to carry it.
What Else You May Need
A compatible power bank is needed if you want to use the USB charging port, because the bag only provides the port and not the battery itself.
Before You Decide
Confirm the 15.6 inch laptop limit, the black finish and the stated dimensions before choosing. If the USB port is important, make sure you already have a power bank to use with it, and check that the water-repellent finish suits the conditions you expect.
