First Impression

The Novoo PowerCube Mini 10000 has a compact form factor. Most similar power banks go for  long and thin, similar a smartphone. Novoo’s design is more cubical. It is thicker with a smaller footprint. For me that fits better into more bag pockets. Thinner accessories can be stacked, but I don’t stack much in my Switch’s carrying case.

Switch power negotiations

Switch power negotiations

The Nintendo Switch charges at the expected rate with a 12V charger. Chargers which offer 12V but not 15V will under perform with the Switch. It under draws power, maxing out at 12W instead of 18W with a 9V or 15V charger. The issue is with the Switch, not the charger. Please note 12W is still more than enough to charge the Switch in handheld mode while you play. Learn more about charging the Switch.

The PD protocol negotiation with the Switch is typical. It connects at 5V and moved up to 12V after negotiations. Current steps up once the 12V connection is made.

The iPhone 8 fast charges when using a USB-C to Lightning cable. We see the usual power negotiations. Connection starts at 5V, then moves up to 9V. Learn more about fast charging iPhones.

The Moto G6 fast charges using the Quick Charge port. This will be the same for Samsung and Quick Charge enabled Android phones. If connected to the USB-C port it’ll charge ~50% slower. The Google Pixel and Android phones that support USB Power Delivery will fast charge on the USB-C port. Learn more about fast charging various Android phones.

Fast Charging Standards Over USB-C & USB-IF Specifications

The Novoo PowerCube Mini’s USB-C port supports more than USB Power Delivery. It also supports Huawei FCP. Its presence on the USB-C connection is against USB-IF specifications.

USB-C includes communication lines, along with power and data lines. The comm lines allow power negotiation without disrupting data transfers. USB Power Delivery uses these comm lines. As does Quick Charge 4+. But fast charging standards which pre-date USB-C do not. Instead they manipulate the data lines to negotiate power. That go against USB-C specifications, as it disrupts data transfers. But one doesn’t use data transfers with a dedicated charger.

In 2016, some USB-C chargers started offering Quick Charge 3.0. A few USB-C focused engineers warned against this practice and cited USB-IF specifications. But the predicted consequences were vague. As it turned out, nothing bad happened. Since then many chargers have operated this way, against specs. But there have been no reports of real world issues.

I have also not run into any issues with these fast charging standards on this or any other charger. But you should be aware of all the information before buying.

If you’re a stickler for meeting USB-C specifications this isn’t a good charger for you. If you’re more pragmatic it works well and has no known issues.


The Novoo PowerCube Mini 10000 is among the smaller USB-C PD power banks on the market. At 10,000mAh it is suitable for commute and travel. With a fully charged Switch you can get 7 hours of play with the most demanding games. It isn’t as fast of a charge as some larger models. But it is more than enough to charge while you play. For the size and price it is a reasonable compromise in performance.

*I did find a discrepancy between the published specs and my testing. The USB-C output is listed as 5V/3A, 9V/2A, 12V/1.5A. My USB Power Delivery PD sniffer reported 5V/2A, 9V/2A, 12V/1.5A. During testing I didn’t see more than 2A @ 5V, backing the PD sniffer’s report. I reached out to Omars. The project manager said 5V output is limited to 2A with USB Power Delivery devices (such as my sniffer). But with regular USB-C devices it can reach 5V/3A. Almost no USB PD devices only charge at 5V, so I wouldn’t expect anyone to see a performance issue.

The PowerCube Mini 10000 can charge a Switch and phone (USB-A) at the same time. But doing so reduces the charge speed to the Switch. With only the Switch it chargers at 12V. When the USB-A port connects the USB-C output drops to 5V. The Switch ends up going from 12W to 9.4W. That’s still enough to keep up with gaming demands. And of course charging two devices will reduce your total Switch playtime.

Bottom Line

The Novoo PowerCube Mini 10000 is a great, compact option for fast charging your Switch. What little you lose in charge speed you get back in size and price. If you like the design but want something smaller check out the Novoo PowerCube Mini 5000.
