Laptop power banks are a tricky thing. Most are only compatible with specific portables, depending on the available output port and the energy transfer rate. Luckily, you’ve got the MaxOak K2 Portable Charger. With a maximum power of 130W and two DC outputs – not to mention a variety of DC adapters included – this power bank is compatible with many laptops. That makes it useful for households with multiple types of laptops and devices. Unfortunately, this isn’t TSA-approved, due to its 185Wh, over the 100Wh TSA standard. However, it’s great for road trips, camping, and train rides.

Pricey compared to other favorites

With just 70wh, the OmniCharge 20+ 20000mah is TSA-approved, making it an excellent companion for work trips abroad and if you have long layovers. It’s compatible with 60W USB-C laptops like the MacBook Pro 13-inch and Dell XPS 2-in-1, but its 100W AC outlet is great for other laptops and other tech gadgets like DSLRs. Finally, it features passthrough charging, so you can charge it while simultaneously powering devices via the AC or USB-A ports. It is a bit more expensive than the MaxOak Laptop Power Bank. However, its versatility does make it worth the higher price tag.

Not very sturdy

The HALO Bolt 58830 isn’t just a portable laptop charger, but it is effective thanks to its AC outlet. This portable charger is also designed to jumpstart a car and is great for laptops that draw up to 60W of power. 

It has its own jump start port and comes with its own jumper cables. And, unlike other portable laptop chargers, which only come in one or two colors, this one comes in seven different colors/design patterns, making it ideal for folks who don’t care for the minimalist approach. 

Unfortunately, it doesn’t have a USB-C port, and the AC outlet should take care of most of your laptop charging needs.

Thanks to its two USB-A ports, you can also charge your other devices. More importantly for travelers and digital nomads, it boasts a svelte and lightweight design – at 405 g, it’s a lot lighter than the iPad Air.

And its PD 2.0 Type C port covers any of the newer USB-C-only MacBooks and can charge any laptop equipped with a USB-C port.

This incredibly high-capacity laptop power bank might have too much power to take on a flight. However, it’s ideal for long road trips. It’s also incredibly versatile, with 28 different laptop connectors and a Magsafe 2 adapter to accommodate just about any laptop under the sun. 

The laptop charger also has a passthrough function that can be easily turned on and off and a LED display that shows the voltage and current battery level. Unfortunately, even though it is the highest capacity charger on this list at 50,000mAh, it can fully charge in 6-8 hours – charging overnight is obligatory.

A bit bulky

The Voltaic Systems V88 Portable Laptop Power Bank has all the necessary features that any great laptop power bank should have, including four outputs, passthrough functionality, and an easy-to-read LCD display for monitoring the battery level and voltage. 

It’s fairly versatile, including 10 laptop adapters that should cover most users’ needs. At 88Wh, it’s also airplane-friendly. The Voltaic power bank is unique, though, because it’s solar-optimized. This means it works with solar chargers and solar panels when traditional power sources are unavailable. 

While those have to be purchased separately, this feature makes the Voltaic Systems V88 particularly useful for those going off-grid.
