Your backpack requires one of these power banks before classes begin.

      Locating an available outlet on campus can demand more patience than signing up for a sought-after class. Common areas such as libraries or lecture halls often lack conveniently positioned sockets. Thus, having a reliable power bank allows for greater flexibility. It enables the choice of a quiet spot in the library, working outside between classes, or completing assignments without the worry of your laptop's battery dying.

      Selecting the right model depends on the devices you carry, as a phone requires significantly less power than a MacBook or gaming laptop. I have chosen four Anker power banks suitable for various needs, from routine phone charging to powering multiple demanding devices simultaneously.

      **Anker Prime Power Bank (20K, 220W)**

      **Pros**

      - Enormous 220W total output capacity

      - Quick 140W single-port charging speed

      - Fast 100W self-recharging input rate

      - TSA-friendly 72.36Wh portable size

      **Cons**

      - High price relative to capacity

      - Heavy build at 510 grams

      - Plastic outer layer easily shows smudges

      The Anker Prime is the power bank I would keep in my backpack for demanding laptops used in fields like architecture, engineering, or animation. Its single USB-C port can provide up to 140W, and with a total capacity of 220W, it can simultaneously charge a laptop alongside a phone, tablet, or another USB-C gadget. The display offers more than just a basic battery percentage, showing real-time charging speeds and remaining runtime estimates, while the companion app allows for further monitoring and power management.

      However, this capability comes with a hefty weight of 1.12 pounds, making it more akin to a portable charging station than a backup phone battery. Students with lighter equipment can opt for a less expensive option, conserving precious backpack space. Nonetheless, for high-demand laptops and multiple device configurations, the Prime delivers the best charging performance among this group. Best Buy has it listed for $129.99, reduced by $50 from its regular price of $179.99.

      **Anker Laptop Power Bank (25K, 165W)**

      **Pros**

      - Huge 165W combined output power

      - Comes with an integrated retractable USB-C cable

      - TSA-compliant flight-approved 90Wh capacity

      - Smart display shows real-time metrics

      **Cons**

      - Fairly heavy at 595 grams

      - Shiny screen is prone to scratches

      - Thick design requires dedicated bag space

      This is the ideal power bank for students who tend to carry all their devices but forget the charging cables. Given today’s reliance on a myriad of tech products, I recommend the Anker Laptop Power Bank as a robust all-in-one solution. It can charge up to four devices at once.

      Anker has included two USB-C cables in the battery: a retractable 27.6-inch cable and a shorter cable that also serves as a carrying loop. Additionally, it features separate USB-C and USB-A ports. Each USB-C port can deliver up to 100W, sufficient for many slim laptops, tablets, handheld gaming devices, and phones. Its 25,000mAh capacity provides longer endurance than the Prime, although the larger battery and cable system increase its weight to about 21 ounces. This makes it a significant addition to a backpack, but the convenience of not having to carry multiple cables may justify the extra bulk. It is currently priced at $104.99 on Best Buy.

      **Anker Nano Power Bank 10K**

      **Pros**

      - Built-in cable doubles as a strap

      - Fast 30W two-way Power Delivery

      - Eco-friendly construction with post-consumer recycled plastic

      - Informative digital battery status display

      **Cons**

      - Built-in cable cannot be replaced by the user

      - Short cable limits device placement options

      - Slightly heavier than its size might suggest

      Many students need backup power for their phones, earbuds, and other portable devices; not everyone uses a high-performance laptop. Therefore, I recommend the Anker Nano for its ability to fulfill basic power needs without weighing down a backpack. It weighs 7.58 ounces and features a built-in USB-C cable for charging devices and recharging the power bank itself.

      A separate USB-C port and USB-A connection provide compatibility with older accessories, and the display updates you on the remaining charge. Its maximum output of 30W is suitable for phones, tablets, a Nintendo Switch, and smaller USB-C devices. However, it is not advisable to use it as the primary charger for laptops. While it may slow down the battery drain on an efficient notebook, larger laptops typically require significantly more power. With a capacity of 10,000mAh and a compact design, the Nano stands out as the most convenient option for daily campus use. Currently, Walmart lists the black version at $49.99.

      **Anker Zolo Magnetic Power Bank 10K**

      **Pros**

      - Good price-to
