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: 5,100mAh
Actual capacities are estimates are based on capacity testing and calculation.
The Xcentz xWingMan Dual has a compact square form factor. Compared to the more rectangular shapes we see from similar power banks. It is thicker than other options, but also offers a smaller foot print. It can fit better in jacket and bag pockets, especially short ones. The exterior has more texture than what we usually see. This helps with the grip, but adds a tiny bit of weight. What sets is apart visually the most is the selection of colors. Most USB-C chargers come in only black. Xcentz offers several colors, including a neon blue, neon pink, and sandstone grey. The model pictured in this review is their sandstone black.
Power Meter Readings
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.
The USB-A port supports Apple 2.4A, so it too can fast charge the iPhone. From 0-30% USB-C PD is faster. But by 50% either port will charge the iPhone at the same rate. 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.
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 USB-C port of Xcentz’s power bank 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 Xcentz xWingMan Dual can fast charge most USB-C phones. Between the two ports it’ll handle the most common fast charging standards. And at 10,000mAh it’ll recharge even the largest phones more than once.
The 18W USB-C Power Delivery port will fast charge USB PD supporting phones. Including newer iPhones, Google Pixel, and Xiaomi models. It can also keep the Nintendo Switch topped off while you play in handheld mode. And will charge less demanding tablets.
With Quick Charge 3.0 offers on the USB-A port it can also fast charge many other Android phones. Including Samsung, Motorola, and any QC supporting models.
The Huawei FCP on both ports will offer fast charging to Huawei phones. It isn’t as good as their newer SuperCharge standard. But you won’t find that on any power bank.
*There is 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. The actual output at 5V depends on what charging standard your device uses. For regular USB-C it will be 5V/3A, hence the listing. But for USB-C Power Delivery (which my sniffer reads) it is 5V/2A. Almost no USB PD devices only charge at 5V, so I wouldn’t expect anyone to see a performance issue.
You can charge using both ports at the same time. But doing so drops the output of both ports to 5V. This removes fast charging for all devices. You can charge two phones at once at their normal rate. In my testing I saw ~15W total output.
Xcentz (pronounced “accents”) has U.S. based support (web, email, chat, phone) and an 18 month warranty.
The Xcentz xWingMan Dual is a compact fast charger for your USB-C phone. Or a regular charger for two phones at once. Also good for small accessories and the Nintendo Switch. But actual capacity is more limited due to the higher output.Buy on Amazon
