The 10 Best 100w Power Bank Reviewed
1. Baseus 100w Power Bank 20000mah
We put the Baseus 100W power bank through its paces, and for a 20,000mAh unit, it’s surprisingly compact. The matte black finish feels good in the hand, though it does pick up fingerprints rather easily. Charging speeds for our devices were impressive, easily handling a full laptop charge and multiple phone top-ups.
One minor annoyance I found was the placement of the power button; it’s a little too close to the USB-C ports, and I occasionally hit it accidentally when plugging in cables. The included USB-C cable is a decent length, but feels a bit thin for a 100W capable device.
This power bank is a solid choice for professionals who travel frequently and need to keep their laptops and other essential gadgets powered throughout the day. It’s built for those who prioritize portability without sacrificing significant charging power.
Who is this *not* for? If you’re looking for a power bank solely for charging a Nintendo Switch or other low-power devices, this might be overkill and you could find a more budget-friendly option. The 100W capability is its main selling point, so you’d be paying for features you might not utilize.
Pros
- Fast charging for laptops and multiple devices.
- Relatively compact for its capacity.
- Solid build quality.
Cons
- Fingerprint magnet finish.
- Power button placement can be awkward.
- Included cable feels a bit flimsy.
2. Ugreen Nexode Power Bank 165w 20000mah
The UGREEN Nexode 165W power bank is a beast, offering exceptional charging speeds that genuinely impressed us. The design is robust, with a textured finish that provides a secure grip. We were able to charge our high-performance laptop and a smartphone simultaneously without any noticeable drop in power delivery.
While the charging performance is top-notch, the unit itself is quite substantial. It’s not the lightest power bank we’ve tested, and you’ll definitely feel its weight in a backpack. The LED display, while informative, could be a bit brighter for outdoor visibility.
This is the power bank for the power user who demands the absolute fastest charging for their most demanding devices. Think content creators, IT professionals, or anyone who relies heavily on their laptop and needs to minimize downtime on the go.
Avoid this if you’re a casual user who only needs to top up their phone occasionally. The 165W output is its defining feature, and if you don’t need that level of power, there are lighter and more affordable alternatives available.
Pros
- Extremely fast charging speeds.
- Charges multiple high-power devices simultaneously.
- Durable build.
Cons
- Quite heavy and bulky.
- LED display could be brighter.
- Higher price point due to 165W capability.
3. Anker Power Bank 20000mah
Anker continues its tradition of reliable portable power with this 20,000mAh charger. We found it to be a well-balanced option, offering good capacity and dependable charging for a variety of devices. The build quality feels premium, with a smooth, almost soft-touch finish that’s pleasant to hold.
While it excels as a travel essential, I did notice that the charging indicators are just simple LEDs, which can be a bit vague compared to a digital display showing exact percentages. It’s a minor point, but for a device designed for ‘best 100w power bank’ consideration, more granular feedback would be appreciated.
This Anker power bank is ideal for the average traveler who needs a dependable way to keep their phone, tablet, and perhaps a smaller laptop topped up throughout a journey. It strikes a good balance between capacity, size, and performance without unnecessary bells and whistles.
This is not the power bank for someone who needs to rapidly charge a high-end gaming laptop or multiple demanding devices at once. Its strength lies in its all-around utility rather than extreme power output.
Pros
- Reliable and consistent charging.
- Premium feel and build quality.
- Good capacity for travel.
Cons
- Basic LED charging indicators.
- Not the fastest for high-demand devices.
- Can be slightly bulky for smaller bags.
4. Ugreen 100w Power Bank 20000mah
The UGREEN Nexode 100W power bank is a strong contender for anyone needing serious portable power. Its 20,000mAh capacity easily handled charging our laptop multiple times, and it delivered fast speeds for our smartphones. The textured grip on the sides is a nice touch, preventing accidental slips.
My main critique is with the included USB-C cable; it feels a bit stiff and less flexible than I’d prefer, making it slightly awkward to manage when the power bank is in a pocket or tight bag. The unit also generates a low, consistent hum when actively charging a high-power device, which, while not loud, is noticeable in quiet environments.
This UGREEN model is perfect for students, remote workers, or anyone who frequently finds themselves away from a power outlet and needs to keep their primary work or entertainment devices running. It’s designed for consistent, high-speed charging when you need it most.
Skip this if you are looking for an ultra-lightweight power bank for minimal charging needs. Its 100W capability means it’s built for more demanding tasks, and its size reflects that.
Pros
- Excellent 100W charging speed.
- Good capacity for extended use.
- Secure grip design.
Cons
- Stiff USB-C cable.
- Noticeable hum during high-power charging.
- Can be on the heavier side.
5. Anker Laptop Power Bank 25000mah 100w
Anker’s 25,000mAh laptop power bank is a powerhouse, offering impressive capacity and the ability to charge multiple devices simultaneously at 100W. The build feels robust and durable, ready to withstand the rigors of travel. We were able to charge a laptop and two phones at full speed without any issues.
While the triple 100W ports are fantastic, I found the overall footprint of this power bank to be quite substantial. It takes up a significant amount of space in a bag, and its weight is certainly noticeable. The glossy finish, while looking sleek, is also prone to showing scratches over time.
This Anker unit is clearly designed for the power user who needs to keep multiple high-draw devices charged for extended periods, such as during long flights or multi-day conferences. It’s for those who prioritize maximum capacity and multi-device charging over ultimate portability.
This is not the power bank for someone who needs a compact charger for their smartphone or a single tablet. Its sheer size and weight make it unsuitable for light travel or casual use.
Pros
- Massive capacity.
- Charges three devices at 100W simultaneously.
- Robust build quality.
Cons
- Very large and heavy.
- Glossy finish can scratch easily.
- Takes up considerable bag space.
6. Rewonder 100w Power Bank 20000mah
We put the REWONDER 100W Power Bank through its paces, and it proved to be a capable companion for keeping our devices charged on the go. The 20000mAh capacity is substantial, offering multiple recharges for most smartphones and a good boost for laptops. Its build quality feels robust, with a textured finish that provides a decent grip, though it’s not exactly premium to the touch.
The 100W output is where this power bank truly shines, allowing for rapid charging of compatible devices. I found it easily handled topping up my tablet while simultaneously charging my phone. The inclusion of a built-in cable is a convenient touch, reducing the need to carry extra accessories, although its length is somewhat restrictive.
Real-Life Usage Scenario: During a long train journey, this power bank was a lifesaver. I was able to keep my work laptop powered for several hours, ensuring I could finish a presentation without hunting for an outlet. It also kept my phone and headphones alive, making for a much more productive and enjoyable trip.
While it performs admirably, the LED display, showing only a numerical percentage, could be more informative with additional indicators for charging status or wattage. For those who prioritize a sleek aesthetic, the REWONDER might feel a bit utilitarian.
Pros
- Fast 100W charging capability.
- Generous 20000mAh capacity.
- Built-in cable adds convenience.
Cons
- Basic LED display.
- Built-in cable is a bit short.
7. Iniu Power Bank 25000mah 100w
The INIU 25000mAh 100W power bank is a solid contender for anyone needing serious portable power. Its substantial 25000mAh capacity means you can leave your charger at home for extended periods, and the 100W USB-C output is impressive, capable of powering demanding laptops. The matte finish feels good in the hand and resists fingerprints quite well.
I was particularly pleased with the array of ports, offering flexibility for charging multiple devices simultaneously. The included USB-C to USB-C cable is also of good quality. However, the sheer size and weight of this unit are noticeable; it’s not something you’d slip into a small pocket comfortably.
Who it is specifically for?: This power bank is ideal for digital nomads, frequent business travelers, or students who rely heavily on their laptops throughout the day. It provides the confidence that your essential devices will remain powered, no matter where your work or studies take you.
While the charging speed is excellent, I did notice the unit can get quite warm during high-power output, which is common but worth mentioning. The indicator lights, while clear, could benefit from a bit more detail beyond just battery percentage.
Pros
- High 100W charging speed.
- Large 25000mAh capacity.
- Multiple ports for versatility.
Cons
- Quite bulky and heavy.
- Gets warm under heavy load.
8. Iniu 100w Power Bank 25000mah
INIU aims for a balance of power and portability with this 25000mAh 100W charger, and they’ve largely succeeded. The claim of ‘smallest’ for this capacity and power is certainly arguable, but it is indeed quite compact compared to some competitors. The textured, rubberized sides offer an excellent grip, making it feel secure when held.
The 100W output is a significant advantage, allowing for rapid charging of laptops and other high-draw devices. I found it charged my MacBook Pro with impressive speed. The LED display is bright and easy to read, providing a clear percentage of remaining battery life. However, the included USB-C cable, while functional, feels a bit thin and might not withstand rigorous daily use for long.
Who it is NOT for: If you’re looking for an ultra-lightweight power bank that can disappear into your bag, this might not be the best fit due to its overall density. Casual phone users who only need a top-up might find the capacity and power overkill.
Despite its compact nature, the unit can still generate a fair bit of heat when pushing its maximum output. While this is expected for such a powerful device, it’s something to be aware of when using it in enclosed spaces.
Pros
- Impressive 100W charging.
- Good capacity at 25000mAh.
- Compact design for its power.
Cons
- Included cable feels less durable.
- Can get warm under heavy load.

The UGREEN Nexode 3 is a powerhouse, boasting a massive 25,000mAh capacity and a staggering 145W total output, which easily covers the 100W requirements for most high-end laptops. The build quality is exceptional, with a solid, premium feel that instills confidence. The matte black finish is sleek and resists smudges well, making it look good even after extensive use.
The array of ports is generous, offering significant versatility for charging multiple devices simultaneously at high speeds. I was able to charge my laptop, phone, and earbuds all at once without any noticeable slowdown. The inclusion of a robust USB-C cable that can handle the high wattage is a welcome addition. My only minor gripe is that the power button feels a little mushy and lacks a satisfying click.
Real-Life Usage Scenario: For a weekend camping trip where access to power was nonexistent, this UGREEN power bank became the central charging hub. It kept my work laptop running for essential emails, my camera batteries topped up for capturing scenery, and my phone alive for navigation and communication. It truly provided power independence.
While the 145W is fantastic, for those who only need to charge a smartphone or tablet, this power bank might be overkill in terms of both capacity and price. It’s definitely geared towards power users and professionals.
Pros
- Extremely high 145W total output.
- Massive 25,000mAh capacity.
- Premium build quality.
Cons
- Power button feel could be improved.
- Overkill for basic charging needs.
10. 27000mah 120w Fast Charging Power Bank
This 27000mAh 120W power bank is built for endurance and speed, offering a substantial capacity that easily surpasses typical smartphone needs and provides ample juice for laptops. The 120W output is a significant step up, ensuring that compatible devices charge remarkably quickly. The unit feels sturdy, with a dense construction that suggests durability, though its matte plastic finish is a bit uninspired.
I appreciated the straightforward LED display, which clearly shows the remaining battery percentage. This makes it easy to gauge when a recharge is needed. The inclusion of multiple USB-C ports, along with USB-A, offers good flexibility for various gadgets. However, the overall form factor is quite bulky, making it less ideal for minimalists or those with limited bag space.
Who it is specifically for?: This power bank is an excellent choice for frequent travelers, remote workers, or anyone who needs to keep multiple power-hungry devices running for extended periods away from an outlet. Its high capacity and fast charging make it a reliable workhorse.
While the charging speed is impressive, the unit can become noticeably warm during prolonged high-wattage charging sessions. This is a common characteristic of such powerful devices, but it’s something to be mindful of.
Pros

- Large 27000mAh capacity.

Frequently Asked Questions
Can a 100w Power Bank Charge a Laptop?
Yes, absolutely. A 100W power bank is specifically designed to charge high-power devices like laptops. This is achieved through its USB-C Power Delivery (PD) port.
It’s important to check that your laptop’s charging port is USB-C and supports PD. Most modern laptops use this technology. The power bank should deliver at least the wattage your laptop requires for charging. A 100W output is usually sufficient for most standard laptops.
How Many Times Can a 100w Power Bank Charge My Phone?
The number of times depends on the phone’s battery capacity and the power bank’s total capacity. A typical smartphone battery is around 4,000-5,000mAh.
A 20,000mAh power bank could theoretically charge a 4,000mAh phone about 4-5 times. However, actual charges are lower due to energy loss. A larger capacity, like 30,000mAh or 40,000mAh, will provide significantly more charges for your phone.
Are 100w Power Banks Safe to Use?
Reputable 100W power banks are very safe. They come equipped with multiple safety features. These protect against common issues like overheating and short circuits.
Look for certifications like UL, CE, or FCC. These indicate that the product has met strict safety standards. Always buy from trusted brands to ensure you are getting reliable safety protections. Avoid unbranded or suspiciously cheap options.
Can I Take a 100w Power Bank on an Airplane?
Generally, yes, but there are strict regulations. Airline policies limit the capacity of portable chargers (power banks) you can carry. The limit is usually 100Wh (watt-hours).
To calculate watt-hours, multiply the mAh capacity by the voltage (V) and divide by 1000. For example, a 27,000mAh power bank with a 3.7V battery is about 99.9Wh. Most 100W power banks fall within this limit. Always check with your specific airline before flying.
What Is the Difference Between 100w Output and 100w Input?
Output refers to the power the bank can deliver to charge your devices. Input refers to the power the bank can receive to recharge itself. A 100W power bank should ideally have a high output and a fast input.
A 100W output lets you charge laptops and other power-hungry gadgets quickly. A high input, like 60W or 100W, means the power bank recharges much faster. This is crucial for a large capacity power bank, otherwise, it takes too long to be ready for use again.
Final Verdict
For the best overall 100W power bank, we recommend the Anker 737 Power Bank (PowerCore 24K). It strikes an excellent balance between massive 24,000mAh capacity, a true 140W output (exceeding the 100W requirement), and rapid 140W input recharging. Its robust build and comprehensive safety features ensure reliability. While slightly pricier, its performance and versatility make it the top choice for charging laptops, phones, and other devices on the go.
