We've all been there: The battery on our laptop is draining while we're away from home, and there isn't an outlet in sight. A laptop power bank is an effective antidote for such trepidation, and we're constantly researching and testing the best ones worth buying. And today, there are plenty of high-quality options at various price points.

You should look for a laptop battery pack with at least one USB-C power output of 60 watts or more. That's the standard for most 13-inch (or bigger) notebooks, so any dependable power bank should have this capability. To be fair, some ultraportable laptops, such as the MacBook Air, can charge sufficiently with 30 watts or less.If you're looking to power up a full-size laptop with a 15-inch or larger display, look for a battery pack with a power output of 85 watts or more. Products with built-in AC outlet(s) can charge just about any laptop, regardless of its screen size. Additional power outputs like full USB ports or a car charger are also worth keeping an eye out for.

We suggest looking for a laptop power bank with a 20,000 mAh or larger battery pack. This capacity will ensure that you can fully charge a laptop and have spare power for a phone, a tablet, and other small gadgets such as wireless headphones or earbuds.A battery pack with enough power to charge a laptop is all but guaranteed to generate heat. The industry's leading products have onboard tech to keep high temperatures in check, protecting the connected devices from overcharging.

A laptop battery pack's portability and size depend on its capacity. The bigger the latter is, the bulkier the product will be. If you want to spend more time away from a power outlet, prepare to carry a heavy power station.

We scrutinized battery packs with sufficient capabilities and the capacity to charge most notebooks. We carefully evaluated each product's ability to charge more than your laptop, too. All the products we selected have at least a duo of charging ports, and some can simultaneously power up even more devices. Design, ergonomics, and durability are important aspects we factored in, along with the products' warranties.

Find your next favorite laptop accessory among the top-rated power banks that made our list. These gadgets are great options and great gifts for students, frequent travelers, and remote workers on the go.

The sleek Anker Laptop Power Bank is our top pick, thanks to a pair of trio USB-C outputs, a rapid USB-A port, ample battery capacity, and built-in tech to protect it from overheating. Available in silver or black, the surprisingly sleek gadget is backed by a robust 18-month warranty.

Best of all, and unlike most rivals, the gadget comes with a pair of integrated cables for charging and replenishing its battery pack. It also has a color display, which shows the power output of each connector you use, its remaining capacity, and battery status.

The 100-watt maximum power output of the battery pack results in USB-C charging speeds that are on par with those of a high-speed AC adapter. What's more, the recharging velocity of the power bank is just as incredible. Using a compatible adapter can fully replenish its battery pack in less than an hour.

Measuring just an inch in thickness, the BoostCharge Pro laptop battery pack by Belkin is thinner than any rival on this list without skimping on charging speed and battery capacity. The accessory’s slim design makes it easy to slip alongside a portable computer into a backpack, a messenger bag, a tote bag, or even the external pocket of a laptop sleeve.

Thanks to a pair of high-speed USB-C ports and a USB-A output, the gadget is as versatile as it is elegant. It also features a handy LED display that shows its charging status and battery capacity. Belkin backs the product with a two-year warranty.

The SOLIX C300 portable power station by Anker is an excellent option for longer stints away from a power outlet. In addition to its many (and versatile) charging outlets, the accessory has a large battery pack that can power up a laptop several times.

Anker has equipped the product with high-tech LiFePO4 batteries. These essential components are longer-lasting and more durable than those found in most battery packs. Anker backs the product with a five-year warranty.

Despite its charging capabilities, we like that the power station weighs less than 10 pounds. It also features an onboard display, an LED light, wireless connectivity, and a companion app.

Goal Zero's Sherpa 100 AC battery pack is feature-packed, yet ultra lightweight (it weighs just a tad above 2 pounds). It packs a duo of high-capacity USB-C ports, an AC power outlet, two full USB ports, and a fast Qi wireless charging pad.

The device's battery pack is sufficient to power up a laptop or deliver multiple charges for smaller devices. A color display will allow you to monitor the device's operation and battery capacity.

Consider the cheaper Goal Zero Sherpa 100 PD if you don't want to drop $300 on a laptop battery pack. It lacks an AC outlet, but its sole USB-C port is plenty capable.

The Goal Zero Venture 75 battery pack is the most rugged on this list and the best option for outdoorsy personalities. The product is water- and dustproof with an IP67 rating. Its port cover and rubber sleeve allow it to survive submersion underwater for up to 30 minutes.

The Venture 75 can simultaneously power up two devices with USB-C and USB-A ports. Its battery capacity is sufficient for a full charge of a compact notebook or multiple smaller-device power-ups.

We like that the product also features a built-in flashlight. The extra feature makes the device even more helpful in emergencies at home or outdoors. Goal Zero backs its creation with a 2-year warranty.

The Nimble CHAMP Pro is today’s most eco-friendly laptop battery pack. Its housing has 90% recycled plastic, and its packaging utilizes recycled paper. The accessory is available in black, white, and blue, and every option has characterful contrasting color accents.

Sporting a pair of USB-C ports, the CHAMP Pro can charge most laptops. Its battery pack has enough capacity to fully power up a notebook, plus other additional gadgets.

The accessory has a high-density battery pack, so it’s sleek and compact. The California-based accessory maker covers it with a 2-year warranty. It also offers an e-waste recycling program.

The EcoFlow DELTA 3 portable power station has a colossal battery pack that can charge any laptop multiple times. It can also power home appliances and heavy-duty tools via surge outlets.

The product's selection of power outputs is spectacular, allowing you to charge up to 15 devices simultaneously. You can recharge the DELTA 3 in an hour and a half with a standard power outlet or in a little over 3 hours with solar panels.

Considering its massive battery pack and many connectivity ports, the 36-pound generator isn’t portable or affordable. However, we believe its capabilities and 5-year warranty are worth it. The device can be a lifesaver during long camping trips off the grid or in case of a natural disaster.
