All power banks list their capacity (mAh) based on the nominal voltage of the battery cells. It does not accurately represent how many recharges you’ll get with the power bank. Actual capacity shows how much power you’ll actually get from a power bank.
You can divide the actual capacity below by your device’s battery capacity. That will give you a realistic estimate on the number of charges it will provide.
- Listed Capacity: 10,000mAh
- Actual Capacity:
- Phone Charging: 7,000mAh
- Switch Charging: 6,200mAh
Actual capacities are estimates are based on capacity testing and calculation.
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 like stacking gear in general.
Power Meter Readings
If you connect to the USB-A port it’ll charge ~30% slower.
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.
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.

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 works great as a portable charger for most USB-C phones. The USB-C side will fast charge newer iPhones as well as Google, Essential, Razer, and Xiaomi phones. The USB-A side with Quick Charge 3.0 will fast charge HTC, LG, Motorola, Nokia, and Samsung phones. It also supports smaller USB-C PD devices such as the Nintendo Switch. But its limited capacity won’t fully recharge larger batteries.
*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 via USB-C and USB-A at the same time. But doing so drops the USB-C output to 5V. With ports on either side you can set this up between you and your travel companion. Be sure you have the right cables to use with both phones.
Novoo is a subsidiary brand under Omars. They have U.S. based support (web, email) and a 12 month warranty on both Omars and Novoo branded products.
The Novoo PowerCube Mini 10000 is a great, compact option for fast charging your USB-C phone or Nintendo Switch. If you like the design but want something smaller check out the Novoo PowerCube Mini 5000.Buy on Amazon
