WINX GO Ultra 20000mAh 100W USB PD Power Bank
Model WX-PB103
Power banks. They are everywhere nowadays. I remember buying my first power bank at the Chinese sourcing expo at the Gallagher Convention Centre many years ago. They have come a long way since then.
The WINX GO Ultra is not just another power bank, what makes this power bank special is that it is able to deliver up to 100 watts (W) of power via the USB Type C Power Delivery (PD) port. A typical locally available fast charge capable power bank is usually rated at around 18W at the time of writing this.
In simple terms, this power bank allows you to charge larger, more power hungry devices like laptops. It also means that it can charge your devices super fast if your device supports high wattage PD.
WINX GO Ultra can also recharge at 65W which means that it will recharge much faster than the typical 20000mAh power bank. I was surprised by this because I did not take note of the 65W input before buying it but noticed this as soon as I plugged it into my 65W capable charger. I have a special cable that shows the charging wattage.
I tested recharging speed with my 65W charger and it took around 1 hour and 15 minutes to fully recharge this power bank from being completely dead which is pretty amazing!
My Samsung S22 Ultra supports up to 45W charging, but it requires Programmable Power Supply (PPS) in order to charge at 45W. This power bank supports PPS up to 33W. I have seen it charging at up to 29W from this power bank when charging my S22 Ultra. This is faster than most “fast” wall chargers!
Charging your laptop:
Some newer laptops do support charging through USB PD and if yours does then no additional cables are required for this to work. With other laptops you’ll need a special cable in order to change your laptop from a USB PD port. These cables are also available under the WINX brand. See the link below for a list of available cables: https://www.winxstore.com/product-category/cables/
These cables have a built-in USB PD trigger that triggers the required volts and amps from the USB DP port (20V*5A). Make sure that your laptop does not need more than 100W otherwise charging from this power bank may not work for you. I tested this functionality with the WINX cable for Asus laptops and it worked as expected.
How does USB Power Delivery (PD) work:
Some USB Type C ports are capable of USB PD. USB PD is a technology that allows for USB PD capable devices to negotiate (also called handshaking) the required voltage (V) and amperage (A) from a USB PD port. A USB PD port usually supports multiple voltage and amperage configurations. Refer the specifications below for the list of the voltage and amperage configurations that are supported by the WINX GO Ultra.

In the box:
The WINX GO Ultra comes with a USB Type A to Micro-B cable as well as a Type C to Type C cable in the box.
Ports:
1x USB Type A up to 18W
1x USB Type C/USB PD up to 100W
1x USB Type A up to 12W
It has a small LCD display on the side which displays the percentage of power left as well as small lightning icons to indicate fast charging.
What could have been better:
This power bank does not support pass-through charging, which means that it can’t charge something while it is being changed. This could have been useful in an instance where you wanted to use it like a UPS.
It would have been nice if it had a Micro-B USB port so that one can charge it from an older cable when you are on the road and can’t find a Type C cable.
Capacity:
I don’t currently have any proper means of testing its actual capacity of power banks. I did try to do a “real world” test. I charged my S22 Ultra from x% to 85% multiple times until the power bank was completely dead and I made notes of the percentage that it charged along the way. It managed to charge my S22 Ultra 219% (more than 2 times). Note that the S22 Ultra has a 5000mAh battery so I got about 11000mAh of real world charging (if the percentage indicator on my phone can be trusted). Also note that my S22 Ultra was on and sometimes being used on while charging and that will have an impact on the result.
I would not expect this power bank to be able to charge a laptop at 100W for longer than say 30-40 minutes due to the rated capacity of the internal batteries of around 74Wh (watt-hour).
You should never expect to get the rated capacity out of a power bank. Here is a detailed article that explains power bank capacity.
Who is WINX:
WINX is a brand by a local distributor, Syntech. Syntech brings a lot of cool tech items into the South African market.
Conclusion:
Overall, I am extremely happy with this power bank. Having a power bank that can charge my laptop in case of emergency is awesome. It is solidly built and it charges/recharges very quickly. It’s a major go! As Flossy Carter would say.
