I used Hyper’s power bank on vacation and when working out of the office. Here’s why I love it.

HyperJuice 245W USB-C Battery Pack review
Your typical dinky iPhone power bank is absolutely no help for keeping a MacBook Pro going for hours when no wall socket is available. You need something serious, like the HyperJuice 245W USB-C Battery Pack.
It’s capable of charging multiple laptops, tablets and/or phones at high speed. And it has enough capacity to greatly extend the time you can use your computer. Maybe a full charge, maybe more — depends on the notebook model.
One of its best features is a display that shows exactly what’s going on with each of the four USB-C ports, and precisely how much power remains in the battery.
- Bigger is better
- Four powerful USB-C ports
- Very useful display
- Add hours of use to MacBook or iPad

Bigger is better
It’s simply not possible to put 27,000mAh into a svelte package. The HyperJuice power bank is a hefty piece of kit. It measures 7.6 inches by 3.4 inches by 1.1 inches, and weighs 1.7 pounds.
You need a laptop bag or backpack to carry it. I tote the power bank around in Hyper’s HyperPack Pro backpack, where I can use pass-through ports to connect the battery to my Apple gear while I carry it all around.
The designers went for a very professional look, and one that matches most Macs. The aluminum part of the casing is close to Apple’s own space gray, with curved edges.
The metal portion of the exterior includes ridges that look great and also help you hold onto the device.
Four powerful USB-C ports
On one end of the HyperJuice power bank are the four USB-C ports mentioned in its name. Two of these can supply up to 100W, and two can supply up to 65W. The total output with multiple devices connected is 245W, but you knew that already.
The HyperJuice 245W USB-C Battery Pack can take in 100W to quickly recharge itself. And it supports passthrough power so it can juice up other computers at the same time.
I like that Hyper didn’t waste space on USB-A. Apple moved on to USB-C, and most of its products ship with cables that use that standard. I have no use for USB-A anymore.
Very useful display
A highlight of the HyperJuice 245W USB-C Battery Pack is its screen. This shows details on every aspect of the power bank. Naturally, that includes how much power is left, expressed in a graphic and as an exact percentage. In addition, the amount remaining is shown in watt-hours.
But that’s only the start. The display has a section for each USB-C port and indicates exactly how much power is flowing in or out.
This is the sort of detail one expects from professional-grade equipment. For comparison, consumer-grade power banks typically make you get by with a single LED that blinks to show an approximation of the remaining charge. Woo.
Add hours of use to MacBook or iPad
As noted, Hyper’s power bank holds 27,000mAh. That’s vastly more than those dinky little iPhone external batteries. To see what that much capacity means in real life, I used it to recharge my 12.9-inch iPad Pro from 2022. Over multiple recharge cycles, it was able to raise the battery level of the tablet 165%.
What that means for your computer depends on the model, and especially the size. MacBooks with larger screens have bigger batteries, so the HyperJuice power bank won‘t be able to give, say, a 16-inch model a 100% recharge.
But it’s definitely going to add many hours of use. It doesn’t bother me to carry this bulky accessory around because I know it’ll keep my notebook and my external display fully charged while working remotely for a few hours. And that won’t even seriously deplete the power bank, so I can do it again the next day.
As noted, two of the USB-C ports can output up to 100W. That’s more than any of my computers can accept, so the charging rate had to be reduced. In my testing, the most I saw was 37W, but that’s a limitation in my testing equipment, not the product.
HyperJuice 245W USB-C Battery Pack final thoughts
When it comes to power banks, I believe in the phrase “go big or go home.” Hyper’s power bank is big in a lot of ways. It stores as much power as any portable battery I’ve tested, it has more USB-C ports than any rival I know of, and its built-in display offers more data than any I’ve tested.
Truly, it’s the go-anywhere source of power that professional digital nomads are looking for.
All that said, it’s bigger than many people want to carry around. It has to be to do all it does, but the size and weight can’t be ignored.
And the price is high enough to put it outside the range of average consumers.
The HyperJuice 245W USB-C Battery Pack is a professional-grade product and is priced to match: $249.99.
You can save a bit without sacrificing too many features with the mophie powerstation pro AC ($199.95). Read my review of this power bank, which also holds 27,000 mAh,
