Does the suitcase charge my phone by itself?

No. The USB port and wireless pad need a power bank connected inside the case. You supply the battery; the suitcase provides the port and pad.

Is it carry-on or checked size?

The Pro line comes in several sizes, and the larger expandable spinners are checked bags. Check the specific size before you fly, since carry-on limits vary by airline.

What does the RFID pocket protect?

It blocks radio signals to cards inside it, such as passports with chips and contactless credit cards. It is a shielded pocket inside the interior organization.

How much extra room does the expansion give?

The expandable zipper adds a few inches of depth to the main compartment. It is enough for extra clothing or souvenirs, but it pushes the bag past some airline size limits when open.

Does it have a laptop sleeve?

Yes. The interior includes a padded laptop compartment and organizer pockets aimed at business travel. The sleeve fits most standard business laptops.

How does it compare with Samsonite's cheaper spinners?

It adds charging, RFID protection and more interior organization. Those features make it heavier and more expensive than Samsonite's basic hardside spinners.
