The dodocool 20100 45W Type-C PD is a rare high output power bank. It is capable of keeping up with small and mid sized USB-C laptops. Its aluminum alloy casing gives it superb cooling. But it has some operating restrictions you should be aware of.

The dodocool 20100 45W Type-C PD was a bit heavier than expected. And cool to the touch. Both are due to the aluminum alloy case. The included 12 inch cable is easier to pack, less likely to get tangled. Shorter cables are also more efficient.
The dodocool 20100 45W Type-C PD offers 14.5V input/output instead of the usual 15V. That goes against USB-C PD standards, but in my testing wasn’t a problem. If you want a fully compliant power bank this may not be the one for you.
This isn’t the first 14.5V USB-C charger we’ve seen. Apple’s now discontinued 29W USB-C power adapter offered 14.5V/2A, giving it the 29W in its name. Apple designed it for the 12-inch MacBook, iPhone, and iPad. But it was also a solid charger for small USB-C devices, including the Nintendo Switch.
The dodocool’s 14.5V output kept up with other 20,000mAh power banks. Its output wattage (voltage x current) was between that of an Anker PowerCore Speed 20000 PD and ZMI QB820. Both of which use 15V output.
From 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).”
I don’t know why. There are reports that combining the Chromebook Pixel and dododcool power bank can lead to hardware damage.
I tested the power bank’s USB-C port with a Nintendo Switch and MacBook Pro (13-inch, 2016). The power bank performed well with both.

Charging the Power Bank
The one technical downside to this power bank is its input is more limited than its output. Many USB chargers will work, but you need a 20V USB-C charger to charge it as quickly as possible.
At 20V it reaches its 30W input limit, charging the power bank in a few hours. A USB-C charger limited to 15V will provide 33% less wattage. Some peculiar 15V chargers, such as the Nintendo Switch AC Adapter, won’t work at all.
Its specs show support for 9V/2A input (18W). But Google’s 18W Pixel charger only provided 6.9W, 25% of what a 20V charger offered. That will take almost 20 hours to recharge the dodocool power bank. A USB-A charger using a USB-C to USB-A cable will also take a full day to charge it from 0-100%.
The dodocool 20100 45W Type-C PD provided a fast charge to a Nintendo Switch and 13-inch MacBook Pro. It even powered the Nintendo Switch dock, a rare feat for a power bank. Its advertise capacity stood up to stress testing. It provided a bit more charge time than the Anker PowerCore Speed 20000 PD and ZMI QB820.
Its aluminum alloy casing does add weight. But the power bank was always cool to the touch while charging one USB-C device. I had to have it charge two devices at the same time to get it up to room temperature. Charging my MacBook Pro 20% increased its external temperature from 74.4°F to 83.4°F. Doing the same with a ZMI QB820 (another 45W output power bank with plastic case) got the temperature up to 93.1°F. As long as it is out of direct sunlight it is a great power bank for anyone charging in warmer environments.
It’s 30W input is matches other 20,100mAh power banks. It is picky about its power source. You’ll want a USB-C wall charger that supports 20V/1.5A to recharge it as quickly as possible. An 18W USB-C charger or USB-A charger will take 20+ hours for a full charge.
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.
dodocool has U.S. based support contacts (email, phone) and warranty service.
The dodocool 20100 45W Type-C PD 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 a USB-C laptop.
