We've all been there: The battery on our laptop is draining while we're way from home, and there isn't an outlet in sight. The panic. The horror!
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.
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 also important aspects we factored in, along with the products’ warranties.
What to Consider
Power Output
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 like the MacBook Aircan 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 a 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.
Battery Capacity
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 like 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 built-in tech to keep high temperatures in check, protecting the connected devices from overcharging.
Portability
A laptop battery pack's portability and size will depend on its battery 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.

The 521 Portable Power Station by Anker is an excellent option for longer stints away from a power outlet. In addition to many (and versatile) charging outlets, the accessory also 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.

The EcoFlow DELTA 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 13 devices simultaneously. You can recharge the DELTA for less than 2 hours with a standard power outlet, or in 4 hours with solar panels.
With a battery pack this large and so many connectivity ports, the 31-pound generator isn't exactly portable or affordable. In our opinion, its capabilities and 24-month warranty are worth it, however.
