Planning on using your laptop while on the road? A small portable charger might be fine for keeping your smartphone and wireless earbuds charged, but you’ll need a portable laptop charger, or one for your tablet, to help your power-hungry devices stay juiced.

A large power bank, like the ones featured in this guide, can rapidly charge a laptop or tablet multiple times (of course, they're capable of fully charging your smartphone and other rechargeable devices, too). Many come packing multiple ports, allowing you to charge a number of devices, all at once. Some even offer a 110V AC outlet that you can use as a power source for your laptop's wall charger!

The Goal Zero Sherpa 100PD seems to be the best portable tablet and laptop power bank for your large devices, offering the best balance of power storage, power output, and flexibility for those who need power on the go.

Omnicharge Omni Mobile 25600

• Capacity: 25,600 mAh
• Watts: 92
• Ports: Two USB A ports, One USB C cable, One DC Port

Weighing a little over a pound, the Omnicharge Omnimobile 25,600 Pro is a large battery. It feels sturdy and capable of withstanding some rough treatment. Its feature set includes a wireless charging pad for your smartphone and a variable DC output for your laptop. This is great news for anyone with an older laptop, as they don't typically support USB charging. While the Omnicharge can charge most laptops, you have to buy the proprietary laptop power cable and connector in order to do so.

The Omnicharge’s USB-C port delivers 60 Watts of juice while its two USB-A ports support QuickCharge 3.0m at 18 Watts each, allowing you to charge mobile devices like iPhones and tablets. We had no trouble simultaneously charging a Chromebook over USB-C, an iPhone XS with the wireless charger, and wireless headphones over USB-A.

Pros

• Nice and sturdy

• Includes a wireless charging pad

Cons

• Large and heavy

How to Choose the Best Laptop Power Bank for Your Device

There are five things you need to look out for when buying a power bank for your laptop or tablet: capacity, power output, ports, and portability.

Capacity: The capacity is the measure of energy the battery can store. The low or high capacity of a battery is recorded in milliamp-hours (mAh) or Watt-hours (Wh). Both of these measurements represent how much electrical energy the battery can release over time. One mAh means the battery can release energy at a rate of one milliamp for one hour. One Watt-hour means that the battery can release a flow of 1 Watt for one hour. Different manufacturers use different numbers for their products, but the bottom line is the bigger the number, the more juice the battery can store.

Power Output: The power output is a measure of how much power the battery can output at maximum. Measured in Watts, the higher this number is the better. If you're charging a laptop battery that can receive up to 60 Watts and can output only 30 Watts, it will take twice as long as it would with one that can give out 60W. A 60W battery will charge more devices at once than a 30W one at full speed.

Ports: Ports are used to connect the battery to the devices you want to charge. USB-A ports are large and rectangular and can be found on most gaming laptops. Some offer built-in cables that have plugs for micro USB or Lightning connectors. You usually see these types of ports on older Android devices or iPads. There's also USB-C, which can handle more energy than USB-A.

Portability: Portability is how easy the battery is to carry around. A smaller battery will hold less charge but will be easier to carry with you. A bigger battery will hold more juice (and thus will be able to charge your laptop several times), but will be harder to lug around.
