Our Picks: Best Anti Theft Backpack With Charger reviews
1. hk Slim Expandable Backpack: A Flexible Pick for Work and Travel
This hk backpack is designed to look slim on a commute but expand when you need more room. Its listed capacity increases from 15L to 27L by opening the expansion zippers, giving you more flexibility for a workday or a short trip. The main compartment fits a laptop up to 17 inches, and the bag weighs 1.65 pounds.
The exterior USB port connects to an internal charging cable, so you can keep a compatible power bank inside the bag and connect your device outside. The power bank is not included. For security, this model uses a hidden back zip pocket rather than a built-in lock. That is useful for keeping small valuables closer to your body, but it is a simpler solution than the BANGE’s lockable compartment.
The bag is made with water-resistant Oxford material and has padded shoulder straps and a back panel. Its listed water resistance is intended for everyday conditions, not immersion or heavy exposure to water. The expandable layout suits commuters who sometimes carry extra items, though the slim profile may be less appealing if you want a permanently roomy bag.
Pros:
- Expands from 15L to 27L
- Fits laptops up to 17 inches
- Hidden back pocket for small valuables
- USB port and internal cable for power-bank charging
Cons:
- Power bank is not included
- Uses a hidden pocket rather than a locking security system
Verdict: Choose the hk if you want a relatively light work bag that can expand for occasional extra cargo and has a discreet pocket for valuables.
2. BANGE Anti-Theft Backpack: Best for a Built-In Combination Lock
The BANGE stands out for its smart combination lock, made from zinc alloy, which is designed to secure a compartment. It has three separate pockets, including a dedicated laptop compartment that fits a laptop up to 17.3 inches. The separated layout can help keep work gear apart from shoes or other personal items stored in the front compartment.
An external USB 3.0 port provides a way to connect a device to a power bank stored inside; the power bank is not included. The backpack also uses water-resistant Oxford fabric and waterproof YKK zippers, according to the product description. These features can help with splashes and wet conditions, but the bag should not be treated as waterproof for submersion.
The lock makes this the most security-focused option in the group, but it also adds a setup step: you’ll need to set the combination using the included instructions. Its capacity and weight are not specified in the supplied details, so shoppers comparing pack volume or carry weight should confirm those measurements before buying.
Pros:
- Built-in combination lock for a secured compartment
- Dedicated laptop compartment fits up to 17.3 inches
- Three separate pockets for different types of gear
- External USB 3.0 port and breathable mesh back and straps
Cons:
- Power bank is not included
- Capacity and weight are not provided in the available product details
Verdict: The BANGE is a strong match if a built-in combination lock matters more to you than a minimal, low-maintenance design.
3. Lixiin Business Travel Backpack: A Compact Option for 15.6-Inch Laptops
The Lixiin is a business and travel backpack sized for laptops up to 15.6 inches. It weighs 2 pounds and measures 17.3 by 11.8 by 8 inches. Its product details describe a main compartment with multiple pockets, a dedicated laptop compartment, and a small extra pouch for accessories.
A hidden zipper design on the surface is intended to make valuables less visible, while the padded laptop compartment helps protect a computer from bumps and abrasion. This is not a lockable bag, so its security approach is closer to discreet storage than the BANGE’s combination lock.
The external USB port connects to an internal cable, but you need to supply a power bank. The breathable mesh back and shoulder straps are designed for comfort, and the water-resistant material is intended to handle light rain and spills. The listed laptop limit is narrower than the 17-inch options, so check your computer’s actual dimensions before choosing this model.
Pros:
- Fits laptops up to 15.6 inches
- Includes a small pouch for accessories
- Hidden zipper design and padded laptop compartment
- USB charging connection and breathable mesh straps
Cons:
- Does not fit laptops larger than 15.6 inches
- Power bank is not included
Verdict: Pick the Lixiin if your laptop is 15.6 inches or smaller and you want a travel-oriented layout with discreet storage and a charging port.
4. BAGSWAN 25L Backpack: Lots of Pockets for Daily Organization
The BAGSWAN offers 25L of capacity, five compartments, and 21 pockets, making it the most pocket-focused choice here. It fits laptops up to 15.6 inches and has room for work documents and everyday items. Two side pockets are described as fitting a 32-ounce water bottle and an umbrella.
For anti-theft storage, the bag combines a hidden rear pocket with an anti-theft main zipper. These features provide discreet storage and an added barrier, though they are not a lock. A luggage strap helps attach the bag to a rolling suitcase, and the listed dimensions are 16.5 by 12 by 7.5 inches.
The external USB port connects to a set-in cable inside the backpack; you’ll need to provide a power bank. The nylon and faux-leather exterior is described as water-resistant and easy to clean. With its many pockets, this bag may suit someone who likes a place for small items, but shoppers who prefer a simple, open interior may find the organization more involved than they need.
Pros:
- 25L capacity with five compartments and 21 pockets
- Hidden rear pocket and anti-theft main zipper
- Fits laptops up to 15.6 inches
- Luggage strap and external USB charging port
Cons:
- Power bank is not included
- Many pockets may feel excessive if you prefer a simpler layout
Verdict: The BAGSWAN is a practical choice if you carry lots of small essentials and want a well-divided 25L bag with discreet storage.
5. HEROIC KNIGHT 25L Backpack: Dual Charging Ports for Everyday Carry
This 25L business backpack fits laptops up to 16 inches and weighs 2.15 pounds. It includes a dedicated laptop compartment, a main compartment, front organizer pockets, two side pockets, a hidden back pocket, and a small pocket on the shoulder strap for a card. A securing strap inside helps hold a laptop or tablet in place.
Its standout feature is the pair of external USB-A and USB-C charging ports, connected to internal cables. You supply the power bank, which stays inside the bag while you connect a compatible device outside. This gives you more port options than the other picks, though it does not mean the bag itself provides power.
The backpack uses 1800D Oxford fabric and has an EVA-padded back panel and mesh shoulder straps. Its water-resistant exterior is intended for light rain and splashes, not complete waterproof protection. The hidden pocket adds discreet storage, but shoppers looking for a built-in lock should consider the BANGE instead.
Pros:
- USB-A and USB-C charging ports with internal cables
- 25L capacity and laptop fit up to 16 inches
- Hidden back pocket and multiple organizer compartments
- Luggage strap for attaching the bag to a rolling suitcase
Cons:
- Power bank is not included
- Hidden pocket is not a locking security feature
Verdict: Choose the HEROIC KNIGHT if you want a 25L work or travel bag with both USB-A and USB-C ports and your laptop is 16 inches or smaller.
How to Choose an Anti-Theft Backpack With a Charger
Check the Laptop Compartment Size
Start with your laptop’s dimensions, not just the screen size printed on its box. The backpacks here have stated limits from 15.6 to 17.3 inches, but a laptop’s shape and thickness can affect fit. If you carry a larger computer, the hk and BANGE options list space for up to 17-inch and 17.3-inch laptops, respectively. The Lixiin and BAGSWAN are limited to 15.6 inches, while the HEROIC KNIGHT lists a 16-inch limit.
Know What the USB Port Does
A backpack USB port is a pass-through connection, not a built-in battery. You place your own power bank inside, connect it to the bag’s internal cable, and plug your device into the external port. Confirm that your power bank and device use compatible connections. The HEROIC KNIGHT lists both USB-A and USB-C ports; the other models list a USB charging port, with the BANGE specifying USB 3.0.
Compare the Security Design
“Anti-theft” can describe different features. The BANGE has a combination lock for a compartment, while the hk, BAGSWAN, and HEROIC KNIGHT use hidden back pockets. The Lixiin describes a hidden zipper design. A concealed pocket can make valuables less visible, but it is not the same as a lock. Consider where you carry the bag and how much extra security you want.
Choose the Right Capacity and Layout
For variable loads, the hk expands from 15L to 27L. The BAGSWAN and HEROIC KNIGHT each list 25L capacity and several compartments. The Lixiin has a thicker profile and a separate accessory pouch, while the BANGE uses three main pockets. If you carry many small items, more pockets may help; if you prefer to pack larger items, a simpler compartment layout may be easier to use.
Understand Water Resistance
Several bags are described as water-resistant, and the BANGE also lists waterproof zippers. These features can help protect your belongings from light rain or splashes, but product descriptions do not establish that any of these bags can withstand submersion. If you expect heavy rain, use a separate protective cover or case for electronics.
Consider Comfort and Travel Features
Padded or breathable mesh straps and back panels can make a loaded backpack more comfortable to carry. The hk, BANGE, Lixiin, and HEROIC KNIGHT describe comfort-focused padding or mesh. For travel, a luggage strap can secure the bag to a rolling suitcase; this feature is listed on the BAGSWAN and HEROIC KNIGHT. Check each bag’s measurements and weight if you need a specific carry-on fit.
Frequently Asked Questions
Do these backpacks include a power bank?
No. The listed USB charging features require you to supply a compatible power bank. The backpack’s internal cable connects that power bank to an external port for your device.
Which backpack has the strongest listed anti-theft feature?
The BANGE is the only option here that lists a built-in combination lock. The other models rely on features such as hidden pockets or a hidden zipper design rather than a lock.
Which option fits the largest laptop?
The BANGE lists a fit for laptops up to 17.3 inches. The hk lists up to 17 inches, followed by the HEROIC KNIGHT at 16 inches. Always compare your laptop’s actual measurements with the backpack compartment before ordering.
Are these backpacks waterproof?
Most are described as water-resistant, not fully waterproof. The BANGE lists waterproof YKK zippers, but that does not establish that the entire bag is suitable for submersion. Protect electronics separately in heavy rain.
Which backpack is best for carrying many small items?
The BAGSWAN has five compartments and 21 pockets, so it offers the most specified organization. The HEROIC KNIGHT also has several compartments and organizer pockets for work and travel essentials.
Can I charge my phone while the power bank stays inside the backpack?
Yes. Each listed charging setup uses an internal cable connected to an external USB port. Keep your own power bank inside and connect a compatible device to the outside port.
Final Recommendation
For a lockable compartment and the largest stated laptop fit, the BANGE is the most security-focused pick. If you prefer a discreet pocket and room to adjust your load, consider the expandable hk. The HEROIC KNIGHT is a useful alternative if you want both USB-A and USB-C ports, while the BAGSWAN suits shoppers who value extensive organization. Before deciding, verify laptop fit and remember that every charging option requires a separate power bank.
