With the best laptop power bank, you don't have to worry about your laptop's battery running down, even if you can't access a wall outlet. Instead, just plug it into the power bank and charge it again. Easy!

Laptops need a lot more electricity than phones to charge, though, so even the best iPhone power banks (opens in new tab) probably won't be powerful enough for this purpose. Instead, you'll need a power bank with at least 18,000mAh capacity, as well as the right ports to connect to your specific laptop. 

To help you find the right model, we've compiled a list of the very best laptop power banks on sale today. Note, too, that they don't just work with laptops but can also be used to charge cameras, tablets, phones, and other devices.

Overkill for most people

Looking for a big beast of a machine, to keep multiple laptops, cameras and other devices topped up, without ever running short of juice? Then you may prefer to invest in something serious, and we recommend the EcoFlow River Max portable power station.

With a mammoth 576Wh capacity, it can be charged from a normal power socket in just over an hour and a half. Alternatively, if you're going off-grid, you can buy solar panels separately, which will charge it in just over five hours in direct sunlight. Or you can use the cigarette lighter charger found in most cars, which again takes about five hours.

At 7.7kg, it's pretty heavy, although if you need less power you can reduce the weight by removing one of the two 288Wh batteries. Outputs include one USB-A fast-charge (18W), one USB-A (5V/2.4A), one USB-C (100W), one 13.6V cigarette lighter, two AC (600W), and two DC. 

Don't get us wrong: this is overkill if you just want to charge a laptop, but if you're taking a ton of electrical equipment – on a photoshoot, say – it's a great choice.

Overkill for most uses

If you're going off-grid with a large crew, and for a long time, then even the EcoFlow River Max above may not be enough for you. In which case, check out the even heftier Goal Zero Yeti 1500X.

This giant portable power station offers a massive 400,000 mAh or 1,516W hours. That's clearly enough to charge a camera battery, let alone a laptop, many times over. You get a ton of outputs, including two AC, two USB-A, one 60W PD USB-C, two 12V car outputs, two 12V power ports, and two Anderson Power Pol (APP). It can be attached to up to 50V's worth of solar panels, and there's even onboard Wi-Fi and a bespoke app to control everything with.

All this comes at a cost, and you'd need quite an extensive setup to justify buying this. But by gosh, it sure is a nice bit of kit.

3. Krisdonia 50,000mAh Power Pack

The best laptop power bank overall

Specifications

Capacity: 50,000mAh
Maximum wattage: 90W
Output sockets: 2x USB-A, 1x USB-C, DC out
Weight: 1.2kg
Size: 195 x 150 x 28mm

Reasons to buy

+
Huge capacity 
+
Charge 4 devices at once 
+
28 laptop connectors 

Reasons to avoid

-
Heavy 
-
Not suitable for flights

Hitting the perfect sweet spot in terms of battery, versatility, and price, the Krisdonia 50,000mAh Power Pack is the best laptop power bank overall. It comes with a massive 50,000mAh battery, which provides enough juice to power a 65W laptop about 2.5 times and a smartphone about 11-18 times. In other words, enough power to keep you going for days on end. 

Alternatively, you can charge both your laptop and other devices, such as smartphones and tablets, simultaneously, using any combination of the power bank's four ports. These are a DC-out for laptops, two USB-A ports for smartphones, and a USB-C port for laptops such as the 12in MacBook, as well as other devices like the Nintendo Switch. Note, though, that the USB-C port doesn't support 20V, so if you have a 20V laptop you'll need to buy a converter.

Passthrough charging is supported, too, which means you can charge the power bank up while it's charging other devices. And it comes with 28 different laptop connectors and a MagSafe 2 adapter, making it compatible with a huge range of laptops, including MacBooks. On the downside, because it's so powerful, it's not TSA-approved so you can't take it on a plane. Also be aware that at 1.2kg, it's quite heavy.

Want to charge a lot of devices at once? Then as long as you're using a Windows laptop or Chromebook (Apple laptops aren't supported), this power bank from Maxoak is the ideal choice. 

It not only comes with a huge 50,000mAh battery, which provides up to 185W of power, but it also has an impressive six ports. These are, in turn: a 20V/5A slot for laptops, a 12V/2.5A slot for digital cameras, two 5V/2.1A ports, and two 5V/1A ports, which cover most smartphones and tablets. You also have 14 connectors for various laptops, and passthrough charging is supported. 

On the downside, it's the heaviest on our list at 1.26kg, and it's so powerful that you're not allowed to take it on a plane.

Not the biggest battery

Even with the best laptop power banks, there's a compromise to be made between the amount you spend and the amount of power you get. And we reckon that this power bank from Anker hits a great balance in terms of value. 

Despite its relatively low price, his power bank comes with a meaty 25,600mAh battery, which allows you to fully charge a 13.4-inch MacBook and charge a Dell XPS 13 up to 90 percent. It's also enough to juice up an iPhone 11 more than five times, or a Samsung Galaxy S20 more than four times. With a USB-C port and two USB-A ports, you can charge up to three devices at the same time. 

There's also a trickle-charging mode designed specifically to provide safe, stable charging to low-powered devices such as Bluetooth earphones. And you get a travel pouch thrown in too. So overall, this offers the best value of all the laptop power banks on this list.

Here's another great laptop power bank that comes in at a nicely affordable price. With a 20,000 mAh rechargeable battery and three outputs – one USB-C PD port and USB-A charge-out ports – you can use this cheap and cheerful power bank to fully charge a 13-inch laptop, or charge multiple devices at once. 

It's compact, slimline, and flight-safe, too, making it a great choice for travel. As Biolite is known for its outdoors and camping products, though, it's worth pointing out that this power bank is not rugged or waterproof. On the plus side, it is the lightest on our list of the best laptop power banks.

Not the biggest battery

Short on cash? Then let us point you to the Belkin Boost Charge Power Bank, which has the lowest price on our list, but still does a decent job of charging your laptop and other devices. 

Admittedly, the 20,100mAh battery is much less powerful than those of the products above. Yet it can still provide, for example, up to nine extra hours of battery life to your MacBook, up to 28 hours to your iPad, or up to 77 hours to your phone. 

You can fast-charge USB-C smartphones with the included cable up to 50 percent in 36 minutes, or an iPhone 8+ in just 30 minutes if you have a USB-C to Lightning cable (not included). Plus, because this laptop power bank comes with both a USB-C and a USB-A port, you can charge two devices at the same time. You can take it on a plane and, as the second-lightest on our list at just 520g, it's a great choice for travel overall.
