Raden's carry-on bag doesn't quite look like a giant iPhone, but it definitely takes inspiration from one. The A22 Carry is the most stylish hard-sided smart suitcase we've seen, delivering both a minimalist design and maximum capacity. The software features are a nice plus, but can use an upgrade.

Physical Features and Carrying Capacity
Raden's smart suitcase line comes in two sizes: the $295 A22 carry-on we tested, and the $395 A28 checked bag. The basic case is a big polycarbonate shell. It isn't entirely rigid—it'll bend when sat or stood on—but it won't break.

Unlike tech-centric carry-ons we've seen from Hedgren and Bluesmart, there's no easy-access outer pocket for your laptop or travel documents; the A22 is one big egg with a long zipper that goes around the edge. The zipper has a water-resistant flap. Light rain didn't leak into the bag, although it created some condensation on the inside of the zipper flap. A little bit of a heavy downpour managed to get in, but less than with competing bags, and even that didn't damage the USB charging ports on the back of the bag, which worked just fine once they dried out. At the top, there's a TSA-friendly combination lock, which is easy to set but not app-enabled the way Bluesmart's is.

On the back, behind the handle, there are two full-size USB ports for charging your gadgets, and a micro USB port for charging the case's internal 7,800mAh battery. A single LED flashes white or blue depending on the case's pairing status.

The case has a dual-extension aluminum handle and four spinner wheels. It doesn't slide as effortlessly as the Hedgren, but I'm okay with that, as the Hedgren tended to float away on slick floors. It comes in eight colors; I'd say don't get the white, as smooth white cases get marked up very easily (as mine did after just one trip in a checked baggage hold).

I packed the A22 for a week's business trip with room to spare, something I wasn't able to do with either the Hedgren Boarding S or the Genius Pack. It's a little bit larger and heavier than those bags: At 22 by 14 by 8 inches (HWD) and 7.5 pounds, it fits all US airline maximum size requirements, but slightly exceeds some European ones. The little bit of extra room really pays off, though.

Inside, there are some nicely segregated fabric compartments. The two halves of the suitcase each have a fabric cover that keeps things in place, and there's a second pouch on the right hand side. There's no compression straps, but the all-the-way-around zippered compartment did just fine containing my pants and jacket. Under another layer on the right side you'll find the 7,800mAh battery, which is completely removable; you can take it with you to charge your gadgets on the go, which is a nice touch.
