WENIG - Anti-Theft Travel Laptop Backpack with USB Charging Port and Lock, Slim Water-Resistant Work Backpack for Men, University Backpacks, Fits Laptops

The WENIG anti-theft backpack is designed for those who need to carry a laptop up to 15.6 inches on daily commutes, business trips, or college. Its slim structure and multiple compartments make it practical for keeping personal and work items organized, and its neutral aesthetic works for both men and women.

It stands out for its balance between security and accessibility: it features a fixed combination lock and a hidden back pocket for valuables, plus an external USB port for charging your phone on the go (requires your own external battery). The water-resistant Oxford fabric, metal zippers, and breathable padded straps provide durability and comfort, while its size of 17.7 x 11.8 x 5.5 inches fits under an airplane seat.

However, its main limitation is that the combination lock is not TSA-approved, so it could be forced during international airport security checks. Also, the USB port does not include a battery, so if you forget the power bank, the cable is useless. For those seeking total waterproofing or needing to open the backpack without a key on long flights, other options with a locking zipper and waterproof pocket would be more suitable.
