Lifeasy Travel Backpack, 35L Carry-On Daypack Flight Approved Laptop Expandable Weekender Multipurpose Trip Bag Business Backpacks with USB Charging Port Black

This is an excellent travel backpack, when it arrived, it was deceptively small and compact! But once you release it from it's plastic prison, it's just like an ever expanding storage paradise! Seriously, you just keep unzipping the darn thing, and it just gets bigger and bigger, quite impressed with just how much volume you have to work with.The material also feels great, you feel like you're getting a durable bag, it's well designed with plenty of pockets/storage compartments. I especially like the built in packing space in the main storage compartment. If i was only looking at the storage capacity and quality of the bag, this would easily be 5 stars, however here's where I feel some improvements can be made.1) I was disappointed that there was not a separate inner compartment/sleeve, or internal pocket solely designed to house a powerbank (something to keep your battery from flopping around your bag as you travel; ie internal velcro strap to keep it from moving or an internal zip/sleeve).2) While it was great that this bag came with an extended USB cable that connects to the external port for ease of access, the quality of the USB cable is poor. While I admire the design, the quality of the cable does not distribute the proper amount of power from the powerbank through the extension cord, to your device. I ran several tests with my powerbank with the USB cable extension and was only lucky to charge 2.5 -3% after 10 minutes. Using my own USB cable and powerbank, I get more than 5-6% after 10 minutes, which is a significant difference (or twice as slow using the bag's feature).I purchased this bag because it gave a lot of versatility in terms of capacity, and design quality; however what pushed me to purchase this product was the convenience of the external charging port access, had I know that it would be significantly less effective at charging my phone, I would have just gotten another bag or a regular one without a port. Call me a charging snob, just don't expect the same speed charging your devices using this extended usb cable and external port.Update: Lifeasy contacted me about my purchase and provide excellent feedback and support with my bag. They have taken my comments/advice under consideration to make improvements to the bag. Now that's what I call great customer service! Looking forward to see how the changes improves the function of the bag. Thanks Lifeasy team!!

Don't buy. The entire main zipper broke within 3 months!!! I left a message to the seller and they never replied to me or tried to resolve the situation. Horrible service.

Update 6 months later. After 5 overseas trips plus daily use as a laptop bag to and from the office, it's falling apart. Zipper compartment holding the laptop is tearing apart. The double zipper itself only works in one direction as the opposite direction will automatically unzip itself. This is a good concept and design, just wish it was more durable.Just received this the day I was scheduled to depart for a business trip to Europe. The backpack passed its first big test-a 1 week international business trip in which it was stuffed to the maximum with a laptop, iPad, computer accessories, 4 days of clothes including an extra pair of shoes and gym clothes, and a notebook. It was packed so full that I had difficulty getting the zippers closed and was concerned about them tearing apart. But they held up just fine. The separate pocket for the laptop makes going through airport security a breeze, and the fact that the main storage opens up like a book instead of a clamshell makes packing and unpacking much easier. So far, off to a good start and hopefully it will last for a long time and many more trips.

The media could not be loaded. I bought this backpack to replace my personal carry on bag for an upcoming trip and as a weekend travel bag. I usually carry two laptops, one for work and my personal laptop for gaming. One is 15' in and the other is 17'; they both fit in the laptop compartment together which is what I needed and I still have spaces to stuff my 17' laptop cooling pad.Very pleased with the outside portable battery connector and the suit case strap. The chest strap buckles can adjust up or down as well as length across your chest. Hopefully, will be convenient for airport travel. The material doesn't feel cheap and it's waterproof. Haven't had a chance to test the durability yet, but will update if anything breaks or changes. So far, so good!

good back pack and feels like it was built with quality. however I received mine with part of the mesh not sowed in correctly. I will most likely return and reorder again. hopefully I'll get one in better condition.

Nice backpack for carrying your laptop and devices around, not so good for fitting clothes and or bathroom stuff in. I wish there was a way to combine the different section into one to hold more in one large space instead of dividing them into smaller zippered sections.The zippers can all be zipped to the top, and all have holes threw them so they can be locked together, which is nice.
