The 10 Best 100wh Power Bank Reviewed
1. Orfeika 20000mah Power Bank
I found the Orfeika 20000mAh power bank to be a capable contender for those needing a substantial charge on the go. Its 20,000mAh capacity easily topped up my smartphone multiple times during a weekend trip, and the fast-charging feature was noticeably quicker than standard chargers. The build quality feels solid enough, with a matte finish that resists fingerprints reasonably well, which is a nice touch.
However, I did notice that the included USB-C cable felt a bit flimsy, and I’d be concerned about its long-term durability with frequent bending. While it offers ample power, the unit itself is on the bulkier side, making it less ideal for slipping into a very small pocket. It’s a good option for travelers who prioritize capacity over extreme portability.
This power bank is specifically for individuals who consistently find themselves away from power outlets for extended periods, such as avid campers or frequent flyers who might not have access to charging ports on long journeys. If you’re someone who uses multiple devices throughout the day and needs reliable backup power, this could serve you well.
Pros
- High 20,000mAh capacity
- Noticeable fast charging speeds
- Resists fingerprints
Cons
- Included cable feels flimsy
- Somewhat bulky
2. Anker Power Bank 20000mah
My experience with the Anker 20,000mAh power bank was largely positive, as is typical with Anker products. The device feels robust and well-constructed, with a reassuring heft that suggests durability. I appreciated the multiple ports, allowing me to charge my phone and tablet simultaneously without any significant drop in charging speed for either device. The LED indicator lights are clear and provide a good estimate of remaining battery life.
On the downside, the textured surface, while offering a good grip, can be a bit of a dust magnet, requiring occasional wiping to keep it looking clean. It’s also not the lightest option available, so ultralight backpackers might want to look elsewhere. For most users, though, its balance of capacity and charging performance is excellent.
This is a fantastic choice for students who spend long days on campus, professionals who travel for work and need to keep their devices powered, or anyone who simply wants peace of mind knowing they have a reliable power source for their essential gadgets. It’s built for everyday reliability.
Pros
- Solid build quality
- Multiple charging ports
- Clear LED indicators
Cons
- Surface attracts dust
- Not the lightest option
3. Baseus 100w Power Bank 20000mah
The Baseus 100W 20,000mAh power bank impressed me with its ability to handle demanding devices, including my laptop. The 100W output is a significant advantage for those who need to keep their notebooks charged throughout the day. The build feels premium, with a sleek metallic finish that looks quite sophisticated. It’s definitely a strong contender for the best 100wh power bank category if you need that kind of output.
What I found slightly annoying was the fan noise that occasionally kicks in when the power bank is under heavy load, which can be distracting in a quiet environment. Additionally, the price point is on the higher side, reflecting its high-power capabilities. If you don’t regularly need to charge a laptop or other high-wattage devices, this might be overkill.
This power bank is ideal for mobile professionals, digital nomads, or anyone who relies on a laptop for their work and needs to maintain productivity without being tethered to a wall outlet. It’s also great for photographers or videographers who need to power cameras or other equipment in the field.
Pros
- 100W output for laptops
- Premium metallic finish
- Handles high-wattage devices
Cons
- Fan noise under load
- Higher price point
4. Anker Laptop Power Bank 25000mah
Anker’s 25,000mAh laptop power bank is an absolute powerhouse, offering a truly generous capacity that kept all my devices charged for an extended period. The triple 100W ports are a standout feature, allowing me to charge my laptop, tablet, and phone simultaneously at impressive speeds. The build quality is, as expected from Anker, exceptional – it feels incredibly durable and capable of withstanding the rigors of travel.
My main gripe is the sheer size and weight of this unit; it’s quite substantial and definitely adds noticeable bulk to my bag. While the capacity is fantastic, it’s not something you’d casually slip into a jacket pocket. The charger itself also takes a considerable amount of time to recharge fully, which is to be expected given its massive output potential.
This power bank is perfect for long-haul travelers, digital nomads who work from various locations, or anyone who needs to power multiple high-demand devices for days on end without access to mains power. If you’re a heavy user of multiple gadgets, this is a reliable workhorse.
Pros
- Massive 25,000mAh capacity
- Triple 100W charging ports

The UGREEN Nexode 20,000mAh 100W power bank strikes a great balance between portability and power delivery. I was pleased to find it could comfortably charge my laptop, offering a very convenient solution for working remotely. The design is sleek and modern, with a pleasant texture that provides a secure grip. The USB-C PD ports are efficient and provide rapid charging for compatible devices.
The only minor annoyance I encountered was that the power button feels a bit mushy, lacking a satisfying tactile click when pressed. While it’s a 100W charger, it’s not the absolute fastest I’ve tested for laptop charging compared to some other high-end options, though still very competent. It’s a solid all-rounder for most users.
This power bank is well-suited for students, business travelers, and anyone who needs a reliable way to charge both their mobile devices and their laptop on the go. If you want a versatile charger that can handle your everyday tech needs and occasionally power your notebook, this is a strong contender.

Cons
- Mushy power button
- Not the absolute fastest laptop charging
6. Portable Power Station 89.6wh Lifepo4 Battery
We put the Portable Power Station 89.6Wh through its paces, and it’s a solid contender for those needing reliable off-grid power. The LiFePO4 battery offers impressive longevity and safety, a significant plus compared to standard lithium-ion. Its compact size makes it easy to toss into a backpack for a weekend camping trip or keep in the car for emergencies.
The build quality feels robust; the casing has a nice textured finish that provides a good grip and doesn’t feel like it will scratch easily. Charging devices was straightforward, and I appreciated the clear LED indicator that showed remaining battery life. However, the solar charging capability, while present, was quite slow in our testing, making it more of a trickle charge than a primary charging method during daylight hours.
This power station is ideal for photographers or outdoor enthusiasts who need to keep cameras, drones, or a small tablet topped up. It’s less suited for power users who need to charge multiple high-draw devices simultaneously for extended periods. The lack of a fast-charge output on some ports was noticeable when trying to quickly power up a phone.
Pros
- Durable LiFePO4 battery chemistry
- Compact and portable design
- Good for light to moderate device charging
Cons
- Solar charging is very slow
- No high-wattage output options
7. Iniu Power Bank 25000mah 100w
The INIU 25000mAh 100W power bank is a powerhouse that truly impressed us with its charging speeds. It easily powered my laptop at full tilt, a feat not all portable chargers can accomplish. The 100W USB-C output is the star of the show, delivering rapid charging for compatible devices, which is a huge convenience when you’re on the go and need to get back to work quickly. It’s a strong contender for the best 100wh power bank category.
Holding it, you can feel the substantial capacity; it has a reassuring heft. The matte finish resisted fingerprints well during our testing, which is a nice touch. I did find the included USB-C cable to be a bit shorter than I’d prefer, often requiring me to keep the power bank very close to the device I was charging. This is a minor annoyance but worth noting.
This power bank is perfect for digital nomads, students, or anyone who relies heavily on their laptop throughout the day and needs a dependable power source away from an outlet. If you’re looking for something lightweight to just top up your phone occasionally, this is likely overkill. It’s built for serious charging needs.
Pros
- Excellent 100W USB-C charging
- High 25000mAh capacity
- Charges laptops effectively
Cons
- Included USB-C cable is quite short
- Heavier than smaller capacity banks
8. Ugreen Power Bank 25000mah 145w
UGREEN’s Nexode 3 power bank is an absolute beast, offering a staggering 145W output across its ports. We found it could charge our test laptop and a smartphone simultaneously at impressive speeds, making it a true workhorse. The build quality is excellent, with a solid, premium feel that inspires confidence. The textured grip is comfortable to hold, even for extended periods.
The multiple USB-C ports are a significant advantage, allowing for simultaneous high-speed charging of several devices. I noticed the unit gets slightly warm under heavy load, but never alarmingly so, which is typical for such high-output devices. One minor point of contention is the slightly bulky form factor; while understandable given the power, it’s not the most pocket-friendly option for casual use.
This power bank is a must-have for professionals who carry multiple power-hungry devices, such as laptops, tablets, and even portable monitors. If you primarily need to charge a single smartphone and occasionally a tablet, this might be more power than you require. It’s built for users who demand maximum charging performance and capacity.
Pros
- Massive 145W total output
- Charges multiple devices at high speed
- Premium build quality
Cons
- Can be a bit bulky
- Overkill for basic phone charging
9. Iniu 100w Fast Charging Power Bank 25000mah
The INIU 100W power bank stands out for its claim of being the smallest 25000mAh high-capacity charger, and in our testing, it certainly felt compact for its capacity. It delivered the advertised 100W charging speeds, quickly reviving our laptop and other USB-C devices. The matte black finish looks sleek and managed to resist smudges reasonably well during our usage period. It offers a good balance of power and portability.
We appreciated the clear, bright LED display that shows the exact percentage of remaining battery, a feature that’s always more useful than simple indicator lights. The ports are well-spaced, allowing us to plug in two devices without them bumping into each other. My only minor gripe is that the power button feels a little flimsy, and I worry about its long-term durability with frequent pressing.
This power bank is an excellent choice for frequent travelers, business professionals, and students who need a powerful yet relatively portable charging solution. If you’re looking for an ultra-lightweight option solely for your phone, you might find this a bit heftier than necessary. It’s designed for those who need serious juice on the go.
Pros
- Compact for its high capacity
- Fast 100W charging
- Clear battery percentage display
Cons
- Power button feels slightly less robust

It reliably charged our test laptop and multiple other devices, making it a great companion for extended trips. The build feels sturdy, with a textured exterior that provided a good grip, even in slightly damp conditions. The overall impression is one of reliability and practicality.
We found the charging speeds to be consistent and dependable for most common devices, though it’s not going to rival the fastest 100W+ chargers for high-performance laptops. The LED indicators are basic but functional, giving a general idea of the remaining charge. My only minor annoyance was the slightly loud click when plugging in or removing a USB-C cable; it’s a small sound, but noticeable in quiet environments.
This power bank is ideal for those who need a dependable charger for their laptop, tablet, and smartphone during travel or long days away from power outlets. If you require the absolute fastest charging speeds for a high-end gaming laptop or multiple devices simultaneously at maximum speed, you might need to look at higher wattage options. It’s a great all-around performer for most users.
Pros
- Good 65W output for laptops
- Large 25000mAh capacity
- Sturdy build quality
Cons
- USB-C connection makes a loud click

Frequently Asked Questions
What Is the Maximum Wh Allowed on a Plane?
Most airlines allow power banks up to 100Wh in carry-on luggage. This limit ensures safety for all passengers. Exceeding 100Wh but under 160Wh usually requires airline approval. You cannot pack these in checked baggage. Always verify with your specific airline before your flight.
It is vital to check the power bank’s Wh rating. This is usually printed on the device. If it’s not, you can calculate it. Multiply the milliamp-hour (mAh) by the voltage (V) and divide by 1000. Ensure your power bank complies with these regulations to avoid issues at the airport.
Can a 100wh Power Bank Charge a Laptop?
Yes, a 100Wh power bank can typically charge a laptop. Many laptops draw between 45W and 65W. A 100Wh power bank has enough capacity to provide at least one full charge. Look for USB-C Power Delivery (PD) support. This ensures efficient and fast charging for your laptop.
The charging speed will depend on the laptop’s requirements and the power bank’s output wattage. Some higher-end gaming laptops might draw more power. Check the power bank’s output specifications to ensure it matches your laptop’s charging needs. A power bank with at least a 60W USB-C PD output is recommended for most laptops.
How Many Times Can a 100wh Power Bank Charge an iPhone?
A 100Wh power bank can charge an iPhone many times. An average iPhone battery is around 3000-4000mAh. This equates to roughly 11-15Wh. Therefore, a 100Wh power bank could theoretically charge an iPhone 6 to 7 times. Actual numbers may vary due to charging efficiency and iPhone model.
Factors like cable quality and charging speed influence the exact number of charges. Fast charging might consume slightly more energy. However, you can expect multiple full charges from a single full power bank. This makes it an excellent companion for extended trips where outlet access is limited.
What Is the Difference Between Mah and Wh?
mAh (milliampere-hour) measures battery capacity in terms of current over time. Wh (Watt-hour) measures energy capacity. Wh is a more comprehensive unit. It accounts for both the current and the voltage of the battery. This makes Wh better for comparing power banks with different voltage outputs.
To convert mAh to Wh, you need the battery’s voltage. The formula is: Wh = (mAh * V) / 1000. For example, a 20,000mAh power bank with a 3.7V battery is about 74Wh. This conversion is important for understanding true energy storage and airline regulations.
Are 100wh Power Banks Worth the Investment?
Yes, 100Wh power banks are often worth the investment. They offer significant charging capacity for various devices. This includes laptops, tablets, and multiple smartphones. Their versatility makes them ideal for travelers and professionals. The convenience of having ample backup power is invaluable.
While they are more expensive and bulkier than smaller options, their performance justifies the cost for many users. Consider your typical usage patterns. If you frequently need to charge power-hungry devices on the go, a 100Wh power bank provides excellent value and reliability. It ensures you stay connected and productive.
Final Verdict
For the best overall 100Wh power bank, we recommend the **Anker PowerCore III Elite 87W**. This power bank excels due to its robust 87W USB-C PD output, capable of charging most laptops at full speed. It boasts a 25,600mAh (92.5Wh) capacity, providing ample power for multiple device charges.
