A travel backpack can look spacious online yet still be a poor fit for your laptop, commute, or carry-on setup. The SHRRADOO Anti Theft Laptop Backpack combines a 40-liter body, a combination lock, a USB pass-through cable, and padded carrying features in one large pack. Its strongest points are organization and travel convenience, but the listing gives conflicting laptop-fit guidance, so you should measure your device before ordering. This review explains where the bag works well, where the security features have limits, and who gets the best value from it.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: College, commuting, and short trips when you need generous storage and organized pockets.
Bottom Line: The 40-liter capacity, combination lock, luggage strap, and padded harness make this a practical multipurpose backpack. Its main tradeoff is unclear laptop sizing, because the listing markets a 17-inch fit while the detailed compartment guidance is smaller.

Key Takeaways
- The 40-liter layout gives you more room than a slim office backpack, with separate areas for a computer, accessories, and travel essentials.
- The combination lock and internal retaining strap add basic protection, but they do not make the entire backpack theft-proof.
- The external USB connection is only a pass-through. You still need your own charged power bank and cable inside the bag.
- Breathable back padding, S-shaped shoulder straps, a chest strap, and a padded top handle improve comfort when the load is adjusted correctly.
- Laptop fit needs extra attention because the marketing title and detailed compatibility fields do not give one consistent maximum size.
What Is the SHRRADOO Anti Theft Laptop Backpack?
The SHRRADOO Bg16017 is a large polyester laptop backpack designed for college, work, and short trips. Its 40-liter body uses a dedicated computer compartment, a main packing section, and a front organizer with smaller pockets, pen slots, and a key hook. The bag also opens from 90 to 180 degrees, which can make packing and security screening easier than with a narrow top-loading design.
The product is aimed at adults who carry a laptop plus chargers, notebooks, clothing, or other daily gear. Its key selling points are the built-in combination lock, USB pass-through cable, luggage strap, and padded harness. You should treat these as convenience features rather than guarantees against theft, impact, or weather damage.
Who Should Buy It?
Best For
- Students or commuters who carry a laptop, books, chargers, and several small accessories.
- Travelers who want a luggage-handle sleeve and a wide-opening main compartment.
- Buyers who prefer one roomy multipurpose backpack instead of a slim laptop sleeve plus a separate day bag.
Skip If
- You need a confirmed fit for a thick 17-inch gaming laptop.
- You want a small personal-item bag or a minimalist office backpack.
- You need a waterproof pack or a lock that secures every zipper and prevents the whole bag from being taken.
Before You Buy: Measure your laptop’s full width, depth, and thickness. The product title mentions a 17-inch laptop, but the listing’s detailed fit information points to a smaller 16.3-inch or 15.6-inch maximum.
Storage and Organization Capabilities
The 40-liter capacity is the main reason to choose this model over a slim commuter pack. You get a separate laptop area, a broad packing compartment for clothing or larger items, and a front section that keeps pens, a key, cables, and small accessories from collecting at the bottom. This layout works best when you assign each section a purpose instead of filling every pocket at random.
The internal shockproof retaining belt helps keep a laptop or tablet from sliding inside its compartment. It does not replace a hard case, and you should still avoid placing heavy objects against the computer. The rectangular shape also makes the available space easier to use, though a full 40-liter load can become heavy quickly.
Laptop Fit and Compatibility
SHRRADOO markets the bag as fitting a 17-inch laptop, while the feature text says the separate compartment holds a 16.3-inch device as well as common 15.6, 14, and 13-inch laptops. A separate listing field states a 15.6-inch compatible maximum. Because laptop screen size does not equal chassis size, two computers with the same screen measurement can fit differently.
Check your device against the bag’s listed 14 x 10.5 x 19.5-inch exterior dimensions, allowing room for padding, seams, and the zipper path. A slim 16-inch notebook may fit more easily than a thick gaming model with a similar screen size.
Pro Tip: Pack your laptop first, then place flat items beside it and heavier items low and close to your back. This improves balance and reduces pressure on the computer compartment.
Security and Device Protection
Combination Lock
The built-in password lock can discourage quick access to the zipper pulls while you commute or wait in a public area. It is useful as a basic deterrent, but it does not protect every pocket, stop someone from cutting fabric, or prevent the entire backpack from being taken. Keep valuables with you and follow the included lock-setting instructions.
Internal Retaining Strap
The internal strap helps hold your laptop or tablet in place so it moves less when you set down or carry the bag. This is helpful during normal walking and transit, but the backpack is still a soft-shell design. Do not expect the strap or padding to protect electronics from a hard drop or crushing force.
USB Pass-Through Cable
The external USB connection lets you route power from a portable battery inside the backpack to a phone outside. The port does not create or store power, and a power bank is not described as included. Disconnect your devices before washing the bag, keep the connection dry, and avoid leaving a charging battery in direct heat.
Comfort and Carrying Design
The back panel and adjustable shoulder straps use breathable mesh with foam cushioning. The S-shaped straps are intended to spread pressure across your shoulders, while the chest strap can help stabilize the bag when it is heavily packed. A foam-filled top handle gives you another carrying option for short lifts.
These features improve comfort, but fit and load still matter. Tighten both shoulder straps evenly, position the backpack high enough that it does not pull backward, and use the chest strap when the bag feels unstable. A 40-liter pack can hold more than is comfortable for a long walk, so carrying capacity should not be treated as a target weight.
Luggage Strap and Wide Opening
The rear luggage strap slides over an upright suitcase handle, which can reduce shoulder strain in airports and hotels. The main section opens 90 to 180 degrees, helping you pack folded clothing and see the contents without digging from the top. Airline size rules vary, so compare the packed bag with your carrier’s current limits before travel.
Material, Water Resistance, and Care
The backpack uses a polyester outer, nylon lining, and a soft-shell construction. The listing describes it as water-resistant, which may help with light rain or small splashes. It is not a dry bag, and water can still enter through zippers, seams, or the USB opening during sustained exposure.
Hand washing is the listed care method. Remove electronics, cables, and the power bank before cleaning. Use mild soap, avoid soaking the lock and USB components, and let the bag air-dry fully before you reload it.
How It Performs in Real Use
For College or Daily Commuting
The separate computer area and front organizer help you divide a laptop, notebook, pens, keys, and charging accessories. The bag makes the most sense when you routinely carry more than a slim office pack can handle. For a light commute with only a laptop and one charger, its 40-liter size may feel larger than necessary.
For Work Trips
The wide-opening main section can hold a change of clothes alongside work gear, while the luggage strap keeps the backpack attached to a rolling suitcase. The combination lock adds a small barrier against casual zipper access. You should still keep identification, medication, and high-value items in a secure, supervised location.
For Air Travel
The rectangular shape and 90 to 180-degree opening are useful for organized packing and security screening. However, the 19.5-inch height and 40-liter volume may be too large for some personal-item limits, especially when fully packed. Check the airline’s current measurements rather than relying on a general “airplane travel” claim.
For Outdoor or Weekend Use
The capacity can handle layers, snacks, cables, and personal items for a day out or a short weekend. Water resistance offers limited protection in changing weather, but the bag is not presented as a technical hiking pack and does not provide waterproof storage. Use a separate waterproof pouch for electronics when rain is likely.
Setup Tips and Common Mistakes
- Test the laptop fit before removing tags. Close the compartment gently and check that the zipper does not press against the computer’s corners.
- Set and test the lock while the bag is empty. Record your combination in a secure place and make sure you understand how to reset it.
- Use a protected power bank. Place it in an internal pocket where it will not be crushed, overheated, or pulled by the cable.
- Do not overpack the outer sections. Excess pressure can strain zippers and push hard objects into the laptop area.
- Balance the load. Keep dense items close to your back and use both shoulder straps instead of carrying the bag from one strap.
Pros and Cons
Pros
- Large 40-liter capacity with separate laptop, packing, and organizer sections.
- Combination lock adds a basic barrier against quick zipper access.
- USB pass-through cable supports convenient phone charging with your own power bank.
- Padded mesh back, S-shaped straps, chest strap, and top handle provide several comfort features.
- Luggage strap and wide-opening design are useful for short trips and airport handling.
Cons
- Laptop size guidance is inconsistent, so a thick 17-inch device may not fit.
- The USB port requires a separate power bank and is not a built-in charger.
- The soft-shell, water-resistant design is not waterproof or impact-proof.
What Buyer Feedback Should You Look For?
Before you decide, read recent reviews for patterns rather than relying on one overall score. Pay special attention to comments from buyers with a laptop close to your device’s actual dimensions. Reviews that mention zipper durability, strap stitching, lock setup, and comfort under a full load are more useful than general statements about appearance.
Also check whether the review applies to the same grey model and size shown on the linked page. Amazon listings can group variants, and feedback for a different capacity or design may not describe this exact Bg16017 backpack.
Is It Worth the Price?
The SHRRADOO backpack offers strong value for the price when you need one large bag for a computer, accessories, and short-trip clothing. The combination lock, luggage strap, USB routing, chest strap, and broad opening give it more travel utility than a basic school backpack.
It is a less convincing buy if your main priority is a guaranteed fit for a large gaming laptop, a compact personal item, or full weather protection. You get the most value when the 40-liter size matches your routine and you are comfortable using the lock and USB port as convenience features, not complete security systems.
How It Compares to Alternatives
A slim MATEIN 15.6-inch laptop backpack may be easier to carry for light commuting, while SHRRADOO’s 50-liter model gives you more packing room for longer trips. A BANGE backpack designed around a 17.3-inch computer is worth comparing when verified large-laptop fit is your top concern.
The Bg16017 makes the most sense when you want a middle ground: more space than a slim commuter bag, but less bulk than a 50-liter travel pack. Its deciding feature is the combination of 40-liter storage, a wide opening, and basic travel organization.
Frequently Asked Questions
Will the SHRRADOO backpack fit a 17-inch laptop?
The title markets the bag for a 17-inch laptop, but the detailed compartment text lists up to 16.3 inches and another field lists 15.6 inches. Measure the full laptop body, including thickness, and compare it with the compartment before buying.
Does the USB port charge a phone by itself?
No. The external port is a pass-through connection for a power bank stored inside the backpack. You need to supply a charged battery and the correct device cable.
Is the backpack waterproof?
The listing describes it as water-resistant, not waterproof. It may handle light moisture, but prolonged rain can reach the interior through seams, zippers, or openings.
Does the combination lock make the bag theft-proof?
No. It can slow casual zipper access, but it does not secure every compartment or stop someone from taking the entire backpack. Keep the bag supervised and use normal travel security practices.
Can it be used as an airline personal item?
The bag measures 14 x 10.5 x 19.5 inches and holds 40 liters, so it may exceed some personal-item limits when full. Compare the packed dimensions with your airline’s current rules before leaving for the airport.
How should you clean the backpack?
The care instructions call for hand washing. Remove all electronics and power accessories, clean gently with mild soap, and air-dry the bag completely before use.
What does the one-year support cover?
The seller states that it will address quality defects that occur during normal use within one year of receipt. Accidental damage, misuse, and normal wear are not stated as covered, so review the current seller terms before purchase.
The Bottom Line
The SHRRADOO Anti Theft Laptop Backpack is a practical choice when you need 40 liters of organized space, a wide-opening travel layout, and basic lock and charging conveniences. Buy it for college, commuting, or short trips after confirming your laptop dimensions; skip it when you need a compact bag, guaranteed thick 17-inch laptop fit, or waterproof protection.
