Laptop power banks are super useful for any time you need to work away from mains power.
When searching for a power bank to charge a laptop or console, you need to keep two things in mind: can it deliver enough power to charge my device, and is the battery capacity high enough to give the battery a reasonable boost?
Laptops and consoles will not charge over a standard USB port: you need one equipped with Power Delivery. These can output up to 100W, but exactly how much you need depends on how much power is required by your device.
Best Laptop Power Bank Reviews
1. RavPower PD Pioneer 20000mAh 2 Port Power Bank (RP-PB201) - Best Overall
RavPower's PD Pioneer 20,000mAh power bank is a really interesting proposition. Though it has two outputs, if you're using only the USB-C Power Delivery output it can ramp up to a massive 60W. We imagine there are very few USB-C laptops for which it won't suffice.
Our only concern with this laptop power bank is how much charge you're actually going to get from it for your laptop. Laptops typically have much higher-capacity batteries than smartphones and tablets, and therefore you need higher-capacity power banks in order to keep them going.
The PD Pioneer is rated at 20,000mAh, which RavPower claims will charge a 13in MacBook Pro 0.84 times. That is still a very useful amount of portable power, if lower than some examples.
A benefit of this smaller capacity is a smaller, less bulky design and, though it's still quite the brick at 369g, its rectangular design is shorter and narrower than most phones (though it is several times the thickness). It's not bad looking in its matte black shell, but it's certainly a rather plain affair, with a small indent at the top corner in which you find the ports and four LEDs that denote remaining power.
RavPower supplies a USB-C to USB-C cable in the box, which is used with the Power Delivery port, but to make use of the second 18W Quick Charge port (full-size USB-A) you'll need to provide your own cable.
Note that the PD output is also the charging input, but in this direction the juice flows at 'just' 30W. That's still super-fast, and given an appropriate wall charger can refill this bank in less than three hours.
2. RavPower PD Pioneer 20000mAh 80W 2-Port Power House - Best Laptop Power Bank with AC Outlet
RavPower has updated its PowerStation with this mighty Power House. The untrained eye might suggest it has knocked 100mAh off the capacity and increased the price, but this is so much better than that.
As previously it is a power bank with a built-in AC outlet, which means you can quite literally plug in your electronics using their mains adaptor. The original version had a 65W output, but here it has been upgraded to 80W, and that makes it suitable for any laptop - even those that do not charge over USB-C.
What you can plug it into really depends on what power they require to operate. Laptop, yes. Hairdryer, no.
The additional ports here have also been upgraded, with the USB-C PD port now supporting up to 30W, and the second a full-size USB-A port with Quick Charge 3.0 up to 18W. Devices plugged into these ports will charge automatically, but to use the AC outlet you'll need to press and hold the small power button on the device's top.
30W will be plenty to charge some USB-C laptops, such as Apple MacBooks, but the MacBook Pro and many Windows laptops will likely require more power.
Recharging this power bank over USB-C should take about three hours, given an appropriately specced wall charger.
Naturally the Power House isn't the smallest of power banks, and it is significantly larger than other power banks of this capacity and weighs in at a chunky 665g.
The difference here is that RavPower supplies a swish hard carry case for carrying the bank and any accessories, as well as a soft mesh case for carrying just the bank itself.
So while it's not as pocketable as some, the RavPower is a delight for its versatility.
3. Anker PowerCore+ 26,800mAh 45W - Best Bundle
This Anker PowerCore+ is a 45W PD power bank with a generous 26,800mAh battery capacity, supplied with a 60W PowerPort Atom III USB-C PD charger that makes it fantastic value.
The Atom III is useful as a replacement mains charger for your laptop, but also for recharging the power bank itself, which is possible in just four hours - incredible for a power bank of this capacity. Of course, if you already have one, you probably don't want to buy another.
The design is typical Anker and, although it's a little basic, it's impossible to fault. The rectangular brick-like device is, as you might expect, incredibly big and heavy (180x80x24mm and 580g), but its metal body and completely rounded edges make it seem much less offensive.
The PowerCore+ is undoubtedly well-made, and feels like a product that will last. It is also supplied with a mesh carry case and a USB-C cable, making it easier to carry together all the necessary attachments for charging your laptop.
We say charging your laptop, but of course the Anker PowerCore+ has plenty of juice for charging your laptop, phone and tablet all at once. The two full-size USB ports support a 15W output with PowerIQ, which in essence recognises the device type to deliver the optimum charge. Meanwhile, the USB-C port is both input and output, able to deliver or accept up to 45W.
4. Zendure X6 - Best Functionality
A 45W USB PD power bank from Zendure, this X6 has the added functionality of performing as a USB hub while connected to your laptop. And it builds in an LCD readout of exactly how much power remains and four full-size USB outputs, one of which is Quick Charge 3.0-compliant.
Looking a little different to previous Zendure power banks, its softer design is still as tough and rugged as they come. There's a 24-month manufacturer's warranty for peace of mind, too.
In common with all Zendure power banks, there's also passthrough charging, incredible six-month standby, higher-than-average 80 percent efficiency and Zen+ tech that can deliver the optimum charge for your device.
The USB hub functionality is supported on two of the full-size outputs, offering data transfer at speeds of up to 480Mb/s. All four USB outputs can also provide power, with one at 18W and the other three at 12W, sharing a maximum output of 45W.
5. Anker PowerCore Speed 20000 PD - Best for MacBook
USB Power Delivery can offer up to 100W in either direction. But the 'up to' here is important: this Anker power bank offers 22.5W, which means it will charge your USB-C laptop only if it meets that requirement.
The 12in MacBook (which ships with a 29W adaptor) apparently does, though our Mi laptop does not. You'll need to carefully check the spec of your laptop, or perhaps the charger you're currently using, to see if it will be supported. Even if it's not appropriate for your laptop, Power Delivery chargers are also useful for fast-charging phones, tablets and consoles.
The Anker PowerCore Speed offers 20,100mAh of power for keeping your devices going, and as such is a lower-capacity and cheaper alternative to some of those in Anker's line-up.
It offers insanely fast charging - and recharging (in just four hours) - with USB-C PD also supported on the input. There's also peace of mind associated with buying from Anker, which is one of the best-known brands in the power bank market.
Of course, you won't actually see 20,000mAh in real terms. Power banks typically operate at between 60- and 70 percent efficiency, so you might get around 13,000mAh for charging your devices.
The design is Anker's standard fare, a rectangular plastic brick with a matte finish and softly rounded corners. Four LEDs are used to show how much capacity remains, which doesn't give an especially precise impression when each LED represents 5000mAh.
The power bank is pretty heavy at 371g, which is understandable given the capacity, but it's elongated design makes it feel bulkier than it is. You'll find it more practical carrying the Anker in a bag than a pocket.
On the side is a button that activates these LEDs to show you what there is at a glance, though charging is automatic when you connect your device. You can add two if you like, with two ports found at one end: one is a USB-C PD port and the other a 10W USB-A output with PowerIQ (tech that identifies your device type and delivers the optimum amount of power).
You can't charge a device a recharge the Anker power bank at once (passthrough charging), though the USB-C PD input means having to charge each device separately is less of a hassle.
How much power do I need?
Check the spec of the wall charger that you use to power the device at home. Ideally you're looking for a figure in Watts, but it may be expressed in Amps and Volts, which you multiply together to get the rating in Watts. If you can't find it here, check the specification on the manufacturer's site or in the paperwork that came with the laptop.
If your laptop or console charges over a proprietary cable rather than USB-C then you can still charge your laptop using a power bank, but you'll need to select a bank with an AC outlet to which you can physically plug in your laptop using its mains charger. In such a scenario the power bank simply steps in to replace your wall power outlet.
