Water Resistant Travel Work School Backpack with USB Charging and Lock

Why the Water Resistant Travel Backpack with USB Charging and Lock Is Essential for Commuters and Students

Picture standing in a packed boarding queue, phone at 9 percent, rain starting to spit — and somewhere behind you, a stranger's hand testing your bag's zipper. This backpack was designed for exactly that moment. Your phone charges from the external USB port wired to the power bank inside. The water resistant polyester sheds the drizzle. And the fixed password lock on the metal zippers means that wandering hand finds nothing but disappointment.

Built for daily commuters, college students, business travelers, teachers, and weekend explorers, this is the best water resistant travel work school backpack with USB charging for people whose whole life rides on their shoulders. A dedicated padded compartment fits laptops up to 15.6 inches (a 17.3-inch variant is also available), a cavernous main compartment swallows daily necessities, and a front organizer keeps pens, keys, and chargers from forming a junk drawer. Seven styles — from classic Grey and Jean Blue to Pink, Gold, and three floral prints — mean it works in a lecture hall or a boardroom. Welcome to the Gorilla Family.

Key Features

• 7 style choices: A-Flower, A-Grey, A-MdFlower, Gold, Jean Blue, and Pink in the 15.6-inch size, plus an X3-Grey 17.3-inch version for big-laptop carriers.
• Premium materials: high quality water resistant polyester fabric with durable metal zippers and reinforced stitching.
• Dedicated laptop compartment: a padded sleeve that holds 13, 14, 15, and slim 15.6-inch laptops snugly (17.3-inch in the X3 variant).
• Built-in USB charging port: an external USB interface with internal cable connects to your own power bank, so your phone charges while you walk.
• Headphone port: route audio from a device inside the bag to your ears outside it — hands and zippers stay closed.
• Anti-theft password lock: a fixed combination lock secures the metal zipper pulls against pickpockets in queues, trains, and crowds.
• Serious organization: a spacious main compartment, front organizer with pen slots, multiple divider pockets, and a built-in key fob hook.
• Luggage strap: a trolley sleeve slides over suitcase handles so the bag rides your roller through the terminal.
• All-day comfort: widened, padded shoulder straps and a breathable back panel for long commutes.
• Large capacity: external dimensions 20 x 11.8 x 5.5 in — laptop, tablet, water bottle, journal, chargers, lunch, and a hoodie, all at once.
• Compatibility: the standard size fits laptops UP TO 15.6 inches ONLY — it does NOT fit 16-inch+ gaming laptops or the 17.3-inch class; choose the X3-Grey 17.3-inch variant for those.

Materials Explained — What Water Resistant Polyester and Metal Hardware Actually Feel Like

The shell is high-density polyester — the same workhorse fabric used in hiking daypacks and airline luggage. It has a tight, slightly crisp weave that beads water on contact, shrugs off scuffs against train seats and lecture-hall floors, and wipes clean with a damp cloth. Water resistant means rain and spills roll off; it is not a dry bag for full submersion, and we will tell you that plainly.

The zippers are metal — heavier and far harder to force than the plastic coils on bargain bags — and they feed into the fixed password lock, a three-dial combination unit anchored to the bag. The shoulder straps are widened and padded with breathable foam, closer to hiking-pack straps than the string-thin ones on fashion backpacks.

The bag itself weighs about 1.5 lb (680 g) empty — light enough that the capacity, not the bag, is what you feel on your shoulders.

Real-World Use Cases

• The Commuter: charges a phone through the external port on the platform while the password lock keeps rush-hour hands out of the main compartment.
• The College Student: carries a laptop, two textbooks, a water bottle, and a hoodie across campus with pens and keys exactly where the organizer left them.
• The Business Traveler: slides the trolley strap over a roller bag handle and breezes through the terminal, laptop padded and accessible for security.
• The Teacher: hauls a laptop, graded papers, and lunch in separate compartments — and never digs for keys thanks to the fob hook.
• The Gift-Giver: picks the floral print for a graduate or the X3-Grey 17.3-inch for the gamer heading to college.

Feature-to-Benefit Mapping

Step-by-Step Setup Guide

1. Set your password lock combination following the included instructions before first use — and store the code somewhere safe.
2. Connect your power bank (not included) to the internal end of the USB cable and stow it in the dedicated pocket.
3. Slide your laptop into the padded compartment and distribute heavier items low and close to your back.
4. Load the front organizer — pens in the slots, keys on the fob hook, chargers in the zip pocket.
5. Adjust both shoulder straps evenly, clip the zipper pulls into the lock, and test the external USB port with your phone.

Troubleshooting and Tips

• Phone not charging from the port? The port is a pass-through — it needs a charged power bank connected inside; check the internal cable is seated at both ends.
• Forgot your lock combination? Work through combinations methodically from 000 — a fixed three-dial lock has 1,000 positions and takes under 30 minutes worst case. Then write the new one down.
• Zippers feel stiff with the lock attached? Unclip the pulls fully before opening — forcing locked metal zippers is the one way to wear them prematurely.
• Caught in heavy rain? The shell sheds showers, but for downpours give electronics a minute of shelter — water resistant is not waterproof, and honesty is the Gorilla way.
• How should you clean it? Damp cloth and mild soap on the polyester — avoid alcohol wipes and bleach, which fade the fabric coating, and never machine wash with the lock attached.

FAQs

Which laptops does this backpack fit?
The standard size fits 13, 14, 15, and slim 15.6-inch laptops in its padded compartment. It does NOT fit 16-inch+ MacBook Pros with chunky cases or 17-inch gaming laptops — for those, choose the X3-Grey 17.3-inch variant.

What comes with it?
The backpack with built-in USB pass-through cable, headphone port, fixed password lock, key fob hook, and trolley strap. A power bank is NOT included — the USB port connects to your own.

How does the USB charging port work?
Plug your power bank into the cable end inside the bag; your phone plugs into the external port. You charge while walking without ever opening a zipper.

Is it really anti-theft?
The fixed password lock secures the main zipper pulls, and metal zippers resist forcing. No bag is theft-proof, but in queues and transit this stops the opportunistic 99 percent.

Is it waterproof?
It is water resistant — rain showers, splashes, and spills bead off the polyester. It is not rated for submersion or sustained downpours, so give electronics shelter in a storm.

How big is it?
External dimensions are 20 x 11.8 x 5.5 in — large enough for a laptop, tablet, books, bottle, and clothes, and it fits under most airline seats.

Is it airline carry-on friendly?
Yes — it fits standard underseat and overhead allowances, and the trolley strap slides over roller-bag handles for the walk between gates.

Is there a headphone port too?
Yes — a dedicated audio port lets you run headphones from a device inside the bag while everything stays zipped and locked.

Are the straps comfortable for long days?
Yes — widened, padded shoulder straps spread the load, and the back panel is padded and breathable for commutes and campus crossings.

Will the colors fade or peel?
No — the polyester is dye-fast and the prints are woven-in rather than surface-printed. Years of sun and rain wear it in, not out.

Is it professional enough for the office?
A-Grey and Jean Blue read fully corporate; Gold, Pink, and the florals bring personality to campuses and creative offices.

Who is this backpack for?
Women, men, and students alike — the fit is unisex, the styles span the spectrum, and the organization works for work, school, and travel equally.

Is this a good gift?
One of the best — graduations, new jobs, back-to-school. The USB port and lock make it feel like a gadget, not just a bag. Free 30-day returns cover any style second thoughts.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all backpacks. If the backpack doesn't suit your needs or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

What Gorilla Family Customers Are Saying

★★★★★
The lock earned its keep in week one
Felt someone tug my zipper on a crowded train — the lock held and they moved on. Laptop compartment fits my 15-inch work machine perfectly and the USB port keeps my phone alive on double-commute days.
— Marcus J., Chicago, IL

★★★★★
Carried me through two semesters
Books, laptop, gym clothes, charger — everything has a place and the straps do not dig even fully loaded. The flower print gets compliments weekly and has survived Texas downpours dry inside.
— Renata V., San Antonio, TX

★★★★★
Best travel companion I have bought
The trolley strap over my roller bag changed airport life, and charging my phone in the customs queue from the outside port felt like cheating. Underseat fit on three different airlines so far.
— Pauline D., Toronto, ON, Canada

★★★★★
Bought the 17.3 for my gaming laptop
Finally a USB backpack that takes a 17-inch machine. Padding is real, zippers feel industrial, and the grey looks smart at client sites. My old bag lasted a year; this one looks ready for five.
— Oliver S., Manchester, UK

★★★★½
Great bag — remember the power bank
Organization and comfort are outstanding and the lock gives real peace of mind. One honest note: the USB port is a pass-through, so nothing charges until you add your own power bank inside. Once I figured that out, flawless.
— Keisha B., Atlanta, GA
