Consumers want to be able to charge their devices as fast as possible and the power bank industry is constantly trying to develop new technologies that can meet this ever-present demand. One such technology is the USB-C power bank.

USB-C power banks have a high-power connection that allows for ultra-fast charging of almost any device. Thanks to its ability to deliver more power, you can also charge significantly larger devices via USB-C. Many power banks now have both USB-C inputs and outputs.

Continue reading this article and learn about all the facts and benefits of the awesome technology that is the USB-C power bank.

How Do USB-C Power Banks Work?

Power banks that have USB-C connections work exactly the same way conventional power banks work. The charging process is exactly the same and this newer type of charging technology is even easier to use than its predecessors.

That’s the awesome thing about modern technology; it’s extremely easy to understand and very user-friendly!

What’s new are the following things:

High-Speed Charging

USB-C power banks can charge your device at a much faster rate than previous USB connections (USB-A and USB-B). We’re talking a slow walk in the park vs. lightning speed here!

A conventional USB-A connection can offer around 2.5W, which is totally sufficient for most smaller devices, such as phones, headsets, cameras, etc. But the charging takes forever (as we all know).

On the other hand, the USB-C technology (given it includes Power Delivery) can deliver around 100W of power to your device. This means that a USB-C power bank can charge your phone up to 70% faster than a conventional USB-A power bank! That’s pretty awesome, isn’t it?

Charges Larger Devices

Thanks to its higher power capacity, USB-C cannot only charge faster, but it can also charge significantly larger and more powerful devices, such as, you guessed it, your laptop or Mac!

To me, that’s a real game-changer, because being able to charge your laptop anytime and anywhere, and fairly quickly at that, is a huge advantage!

Conveniently, most newer laptops and MacBooks now have USB-C ports for both charging and data transfer.

Reversible Connections

The reversible connections is perhaps the most convenient feature of the USB-C! I don’t know about you, but I always managed to plug in a USB the wrong way…always! On several occasions, I also managed to damage the plug. I’m sure many of you can relate.

Well, with the USB-C, that problem is a thing of the past! Not only are the cable’s two connectors reversible, as they are virtually the same on each side, but the port is double-sided as well, which means that, no matter which way you stick in the USB-C, either side will always be the right one. Finally!

Universal Compatibility

Remember when you had two buy different cables with different connectors for your devices? It seemed as if every company had its own personal plugs and ports, right?

That’s another thing you can skip thinking about now! The USB-C was developed with broad compatibility in mind and virtually hundreds of tech companies came together to figure out the design. Among these are big names like Apple, Google, Intel, Microsoft, Dell, and many more.

This basically means that all new devices that are entering or will be entering the market in the near future will have USB-C connections. One power bank and one cable for all of your devices!

What Devices Can You Charge with a USB-C Power Bank?

As mentioned above, it’s only logical that more and more tech providers will adopt the USB-C standard in the coming years, which will mean that you can basically charge any device with a USB-C power bank.

As of right now, most new mobile models already have USB-C ports, and so do many of the newer laptop and MacBook versions.

Smaller devices, such as radios, lamps, headsets, mice, keyboards, loudspeakers, outdoor gadgets, etc, still mostly have conventional USB connections, but they’ll most likely follow suit soon as well.

In the meantime, you can still use a USB-C power bank to charge such devices, as virtually all of them still come with at least one USB-A and/or USB-B and/or micro USB port.

How Long Time Does it Take to Charge a USB-C Power Bank?

The really cool thing about the USB-C technology is that it doesn’t only speed-charges your devices but also the power bank itself.

Given that you are using an 18W USB-C wall charger, which is a relatively newly developed power adapter that will be necessary if you want to charge your power bank via a USB-C cable, the charging time of your power bank can be reduced by 50% or more.

Here is a little guide I put together on the charging times for several USB-C power banks with different capacities. You can check out all of them on Amazon if you want to take a closer look:

Power BankCapacityApprox.
Charging Time
INIU Portable Charger10,000mAh4h
Anker PowerCore Essential20,000mAh7h
Charmast Slim Thin 3A High-Speed Battery Pack26,800mAh9h
ROMOSS 30000mAh Power Bank Sense 8+30,000mAh11h
MAXOAK Laptop Power Bank50,000mAh8h (High-Speed Charging)

Pro Tip: Not all USB-C power banks come with the required 18W wall charger, so make sure you purchase one as well if you want to take advantage of the USB-C’s fast charging capabilities. You can find an 18W USB-C power adapter that’s perfectly suited for charging phones on Amazon here.

Are USB-C Power Banks Expensive?

Most USB-C power bank models are very decently priced and are actually not much more expensive than regular power banks.

Nowadays, the technological development is moving at an ever-faster pace, and consumers want the most efficiency at the lowest possible price.

Couple that with constantly dropping costs for materials and batteries and you’ve got yourself a super-efficient, high-speed charger at a very affordable price.

USB-C devices especially have become cheaper very fast, which is something that took many in the industry by surprise.

Many experts and power bank fans, like myself, thought it would take a few years to see current price levels. Well, as I said, things move fast nowadays!

And that’s why you can buy a high-capacity USB-C power bank of 30,000mAh or more for less than $50 and a laptop or MacBook power bank for approximately $100-$150.
