NusGear 20000mAh 100W Power Bank Review
The NusGear 20000mAh 100W power bank can charge an iPhone 11 by 50 percent in 30 minutes, which is faster than the majority of portable chargers we’ve reviewed. Moreover, due to its high output, you can easily charge laptops such as the MacBook Pro or other power-intensive devices like drones or gaming consoles.
Charging Technology
The NusGear 20000mAh power bank is compatible with a range of USB and USB-C devices, including an iPad Air, iPhone XS Max, Kindle, MacBook, and more. In fact, there are very few devices it isn’t compatible with. This small power bank offers 20000mAh of power, enabling it to charge an iPhone 8 Plus 5-6 times, a Samsung Galaxy S9 4-5 times, and a MacBook Pro once. These numbers are impressive, meaning you could use this power bank for a weekend away and use amongst two people with no issues.
Recharging the NusGear power bank is quick and convenient, as it provides multiple charging options such as using an AC adapter, car charger, Type-C wall charger, or USB C charger and connect it to your laptop. Charging it with a regular adapter will take around 9 hours. However, for a quicker charge, it’ll reach 100% battery in 5-6 hours using a fast charge wall charger with a mico port. Or, if you’re using an 87W charger with a USB C port, then it the NusGear 20000mAh can charge in as little as 1 hour!
The main fast charging technology powering the NusGear 20000mAh 100W power bank is Power Delivery, which allows you to boost an iPhone 11 Pro’s battery by 50 percent in 30 minutes. You can also fully charge a MacBook 2016 in 4.5 hours. It also comes with Quick Charge 3.0 but unfortunately, it does not have passthrough charging like the RAVPower 60W power bank for example.
In terms of ports, it features 4 different options:
- Micro USB input
- USB type C in/out with Power Delivery
- USB type A with QC 3.0
- USB type A with adaptive charge
With the 3 output ports available, you can charge multiple devices at the same time.
Portability
The NusGear power bank measures 7.1 x 3.3. x 0.9 inches, which is 2 inches longer than the iPhone X, and longer and deeper, too. Compared to other power banks with a similar capacity, such as the Sdoutech charger, it’s 1 inch longer, which might make it inconvenient to store in your pocket while you’re boosting your smartphone.
At 1.29 pounds it’s not the lightest power bank we have reviewed. As a result, this weight can make it inconvenient for holding the device while charging, such as at a festival or while walking and charging your phone. Fortunately, the size dimensions allow you to keep it in your backpack.
Look and Feel
The NusGear 20000mAh 100W power bank is finished in a striking black with a slight sheen, though, it’s not available in other colors or designs. The NusGear name is showcased on the bottom light in a contrasting white font, but we feel a smaller size would make the device look more stylish.
On the top right, it mentions that it has 20000mAh of power, which users will already know and makes it look slightly cheaper than what it costs. On the other hand, the curved edges make it feel softer in your hand and prevent the device from bashing into other belongings in your bag.
The NusGear is designed with a scratch-resistant metal shell, as opposed to plastic, allowing it to remain durable, so you don’t have to worry about placing it on hard surfaces. This material also feels smooth to touch.
On the side of the unit are LED indicators that monitor the power status—a handy feature for seeing how much charge remains. These indicators are small, which adds elegance and can make it useful if you use the power bank even at night. The percentage for each indicator is 20%, thus you won’t be notified of a low battery at the last minute, which is extremely helpful. Each stage will glow a brighter blue than the other lights, though, the contrast isn’t too much and we’d prefer if the remaining lights were dimmed more.
Durability and Build Quality
This device comes with many safety features that make it secure for everyone to use:
- Short-circuit protection.
- Overheat protection.
- Over-voltage protection.
- Over-current protection.
There aren’t any further features such as being shockproof and waterproof, but the main focus is clearly on the device’s quick-charging technology. Plus, the durable metal shell makes it less prone to breaking if you drop it on the floor.
We also couldn’t locate any information on the charge cycles, but, some customers reported that the device stopped working after a couple of months for unknown reasons.

Pros
High output power - 100W
It has both Power Delivery and Quick Charge 3.0
4 different ports
Sturdy build with metal case

Cons
A bit heavy
No pass-through charging
Final Thoughts
The NusGear 20000mAh 100W power bank is powerful and charges your devices quickly and safely. It sticks to its promises and will protect your smartphone during charging, too. Its larger than average weight can be off-putting for those who want a lighter unit to store in their purse or hold on the go while using. Though, its versatility for a range of devices makes it a winner in our eyes.
