  1. Mophie Powerstation AC

The highest output portable battery

Capacity: 22Ah | Outputs: 1 x AC, 1 x USB-A, 1 x USB-C

100W output

USB-PD compliant to fast charge the latest iPhones

A bit pricey

With the Mophie Powerstation AC, high power output is the name of the game. This portable laptop battery charger is able to power a 15-inch MacBook Pro. Meanwhile, the USB-C port is rated at 30W with a USB-PD label, meaning its one of the few batteries capable of fast charging an iPhone X or iPhone 8.

  1. Omni 20 USB-C

For when you also need a USB hub

Capacity: 20100mAh | Outputs: 2 x USB-C, 2 x USB-A | Notebook Connectors: N/A

High capacity

Lots of ports

Kind of expensive

If you have a newer laptop, and find yourself running out of juice throughout the day, the Omni 20 USB-C might be for you. Not only does it have an insanely high capacity, but it also allows charging of multiple USB-C devices simultaneously. So, if you’re working and you need to charge your Nintendo Switch and a mobile device, you go for it. Plus, the Omni 20 also serves as a USB hub, clearing out some extra storage space in your bag.

Long warranty

Tons of connectors

No Type-C connectors

The PowerAdd Pilot Pro2 doesn’t just come with 10 connectors that cover most of the laptops on the market today, but it’s backed by a two-year warranty. That means you can use the 23MAh/85Wh capacity without worry. The Pilot Pro2 is also light enough to carry around wherever you go, coming in under 560g. The only thing that holds it back is that it doesn’t have any USB-C connectors, so if you have a modern Ultrabook or MacBook, you may want to go elsewhere, otherwise you’ll have to carry a separate power supply to keep the battery charger backed up.

  1. RAVPower RP-PB058

Geared towards newer notebooks

Capacity: 26.8Ah | Outputs: 1 x Type-C, 2 x Type-A | Notebook Connectors: 0

Just about the max capacity you can take on a plane

Type-C in there


As technology marches forward, new laptops need less power to function. This is especially ture for high-end laptops like the MacBook Pro, HP Elite x2, Huawei Matebook Pro X or the Dell XPS 13. For all of these devices, and more, USB-C is king – the RAVPower uses this revolutionary connector to deliver up to 30W of power, which should be plenty for the best Ultrabooks. You can recharge it using a 30W wall charger that can also be used to power compatible laptops – very handy, indeed.

  1. MaxOak Apple MacBook Charger

Ideal for those with an Apple notebook

Capacity: 36Ah | Outputs: 2 x Type-A, 1 x Type-C, DC-out | Notebook Connectors: 3

Massive capacity

Plenty of connectors


The MaxOak MacBook Charger is a perfect example of a laptop battery charger that goes the extra mile to make sure that it matches the expectations of its audience. This portable laptop charger has all the hallmarks of an Apple device, without the logo – but that’s what those Apple stickers are for – with a matching brushed aluminum finish.

It’s the second most capacious portable laptop battery charger on this list, but its huge amount of juice comes with a catch – it carries so much power that at least one airline has outright banned it, so bear that in mind if you plan to use this charger while traveling. It’s also pretty heavy at almost 1kg and will cater to most MacBooks, but nothing else.
