The dodocool 20100 45W Type-C PD is an aluminum encased power bank. It offers 45W output and excellent temperature control. But you’ll need to work around a couple of operating restrictions.

First Impression

The dodocool 20100 45W Type-C PD was a bit heavier than expected. And cool to the touch. It has an aluminum alloy case instead of plastic. That added a few more ounces, but provides great temperature control. The included 12 inch cable is easier to pack. And shorter cables are more efficient. Its printed specs showed 14.5V output/input, not the standard 15V. That didn’t present a problem in later testing. But it was something I needed to look into.

USB-C Standards

The dodocool 20100 45W Type-C PD doesn’t meet with USB-C standards. To be fair, most power banks don’t. If they include Quick Charge or support Apple’s “fast charge” they violate USB-IF’s standard. There’s only one USB-IF certified power bank on the market that I’m aware of (Anker PowerCore Speed 20000 PD). But dodocool’s power bank doesn’t meet up for two less common reasons.

One, it uses 14.5V output/input instead of the standard 15V. Two, it listed two laptops as being “not compatible.”


Under strict USB-C PD standards 14.5V is not supported. But we know strict USB-C PD standards are not upheld by many USB-C devices. The Nintendo Switch itself is a prime example. They all should. It would make things easier for end users. But that isn’t how most products work out. And for the most part it isn’t a problem for end users.

With USB-C PD chargers and power banks 14.5V is unusual, but not unheard of. The most popular example is the Apple 29W USB-C Power Adapter. It offers 14.5V/2A, hence the 29W in its name. Apple designed it for use with the 12-inch MacBook, iPad, and iPhone. But other reviews have found it works quite well for the Nintendo Switch. Apple has recently released a 30W USB-C power adapter to replace the 29W model. Among the updates are support for 15V/2A. I hope the next version of dodocool’s power bank follows the same path. But until then the current model works, as Apple’s power adapter did.

Charging the Switch with 14.5V

My testing of the dodocool power bank with the Nintendo Switch found no issues. The Switch drew 14.3V or 14.4V (the variant is normal and present in 15V chargers) from it. Total wattage charging the Switch in various states lined up other 15V power banks.

Charging the Power Bank with 14.5V

I had a couple of issues while testing its 14.5V input, but nothing unexpected. dodocool’s documentation says to use USB-C PD chargers rated 30W or more. They recommend their own charger, Apple’s 29W/61W/87W chargers, and a few other laptop chargers. For ideal charging it wants a charger with 20V/1.5A output. It charges slowly if using other voltages. I tested every charger I had.

  • Anker 30W: 19.8V/1.45A (28.7W)
  • Apple 61W: 20.1V/1.45A (29W)
  • Inateck 60W: 20V/1.45A (29W)
  • Google 18W: 9V/0.77A (6.9W)
  • Nintendo 39W: No charge
  • ZMI 45W: 19.7V/1.41A (28W)

Google’s 18W charger worked, but at a reduced power draw. It is below dodocool’s charger recommendation (18W vs 30W).

The Nintendo Switch AC Adapter didn’t work at all. But this isn’t the first time I’ve had problems with that charger. The Switch’s AC adapter power profiles are all unusual. It’s designed for the Nintendo Switch, nothing else. It can charge some power banks. But I’ve had as many failures with it as successes, and often recommend it stay with the dock full time.


The 14.5 voltage works fine with the Switch. But it would never qualify for USB-IF certification. If you want to stay within strict USB-C PD standards this is not the power bank for you. I didn’t find anything to complain about.

To charge the dodocool power bank you’ll want a 30W or higher USB-C PD charger. You can use a USB-A charger, but it’ll take 20 hours to charge from 0-100%.

Incompatible Laptops

From the dodocool’s product page:

Not compatible with Google Chromebook Pixel (12.85″, 2015) or HP TPN-C127 (HP Spectre Notebook, HP Spectre Notebook 13t, HP Spectre Notebook 13, or HP Spectre Notebook PC).

Why? I don’t know.

Freelance hardware engineer Nathan K put out a warning on the matter. One of his readers informed him that they used the power bank with their Pixelbook. “As a result, it is non-functional.” It isn’t clear if the laptop or power bank become non-functional. The affected user wasn’t able to run tests, and Nathan K never did any testing. The incompatible listing was present at the time of Nathan’s post. Nathan K points out that had it followed strict USB-C PD standards this wouldn’t be the case.

Again, the power bank worked fine with the Nintendo Switch in my testing. I also tried it with my 13-inch MacBook Pro and had good results. The power meter read 19.7V/2.12A with the MacBook running and setup to induce max power draw. That lines up with the Apple;s own 61W USB-C power adapter (20V/2.25A).

Is This Power Bank Safe?

Yes, for the Nintendo Switch. No, for one of the listed incompatible laptops.

I experienced no issues myself. Charging the Switch went as well as my previous reviews. Charging the power bank also went fine, provided you give it what it wants. dodocool has documented its quirks, which is always appreciated. Other reviews for this power bank (beyond Amazon) also reported good experiences.

I recommend you consider the issues and details I’ve mentioned. As well as the other pros and cons listed elsewhere in this review. Then decide if, like with any product, its pros outweigh its cons.


The dodocool 20100 45W Type-C PD provided a fast charge to the Nintendo Switch in handheld mode. It recharged the Switch 3 times (my testing totaled exactly 299%), offering 9+ extra hours of gaming. Its rare 45W output allows it to power the Nintendo Switch dock. That isn’t of concern for many. But with USB powered monitors a few Switch owners have taken mobility to extremes.

Its aluminum alloy casing adds some weight. But the power bank was always cool to the touch while charging the Switch. I was able to raise it to room temperature by charging both the Switch and a phone. Other power banks are warm through their plastic casing after a few minutes of use. As long as it is out of direct sunlight it is a great power bank for anyone charging in warmer environments.

Its 30W input is similar to other 20,000mAh power banks. It is picky about its own power source. It won’t work with the Switch’s AC adapter. An 18W charger under performs. A USB-A charger will take almost a full day (same as other 20,000mAh power banks). And you’ll need to provide the USB-C to USB-A cable. With a 30W USB-C PD charger you can recharge this power bank in 3.33 hours. Disconnect it at 3 hours and you’ll have 98% capacity.

Do not use this with a Google Chromebook Pixel or HP Spectre laptop. As detailed above, dodocool lists them as being incompatible. Likewise, be aware of its 14.5V output/input instead of the standard 15V. It didn’t cause any problems or reduced performance in my testing. And it isn’t the first USB-C PD charger with that voltage offering.

Compared to its peers the dodocool offers great output and temperature control. And it does so at the bottom of the price range. It is among the power banks to consider if you own both a Switch and a USB-C laptop.

dodocool has U.S. based support contacts (email, phone) and warranty service.

Bottom Line

The dodocool 20100 45W Type-C PD is a good, high capacity power bank for both the Nintendo Switch and most USB-C laptops. It’ll stay cool while you charge either and your phone. You’ll want a 30W USB-C PD wall charger to charge it as quickly as possible.
