INIU 140W Power Bank, 27000mAh High Capacity Laptop Portable Charger
The INIU 140W Power Bank is a beast when it comes to keeping your devices charged. With a massive 27,000mAh capacity, it can recharge your laptop, tablet, and phone multiple times. The 140W USB-C port is a game-changer, delivering lightning-fast charging for power-hungry devices like MacBooks. Plus, the smart digital display keeps you in the loop about power levels and charging speeds.
I was impressed by its sturdy build and sleek matte black design—it feels like it can take a beating. The multiple ports (USB-C and USB-A) make it super versatile, though it’s not exactly pocket-friendly due to its size and weight. Perfect for travel or emergencies, but keep in mind it takes 3-4 hours to recharge itself.
Pros & Cons:
| Pros | Cons |
|---|---|
| Blazing-fast 140W charging | A bit bulky for everyday carry |
| Smart digital display | Takes a while to recharge |
| Multiple ports for flexibility | Some users report inconsistent speeds |
INIU Power Bank, 20000mAh 65W USB C Laptop Portable Charger
After testing the INIU 140W, I was curious about its smaller sibling, the 20000mAh 65W model. This one’s a solid pick if you’re looking for a balance between portability and power. It charged my MacBook and iPhone quickly, and the 65W output is plenty for most laptops. The digital display is a nice touch, though it can be a tad off at lower percentages.
What I loved most was its fast charging—it’s a lifesaver when you’re in a pinch. The build feels durable, and the included mesh bag for cables is a thoughtful bonus. Just be prepared for a longer recharge time if you’re using a lower-wattage charger.
Pros & Cons:
| Pros | Cons |
|---|---|
| Fast 65W charging | Takes a while to recharge fully |
| Compact and easy to carry | Display can be slightly inaccurate |
| Comes with a handy mesh bag | Not ideal for high-power devices |

The Anker 737 is a powerhouse for anyone who needs reliable, high-speed charging. With a 24,000mAh capacity and 140W output, it’s perfect for laptops, phones, and other USB-C devices. The smart digital display is a standout, showing real-time info like battery percentage and charging speed. It’s compatible with MacBooks, iPhones, and Samsung Galaxy models, making it super versatile.
One of its best features is the ability to charge multiple devices at once via its three ports (2 USB-C, 1 USB-A). It’s a bit on the heavier side, but the robust build and high capacity make it worth it for frequent travelers or remote workers. Just a heads-up—it doesn’t come with a wall charger, which is a bummer given its premium price.
Pros & Cons:
| Pros | Cons |
|---|---|
| Fast 140W charging | A bit heavy for portability |
| Smart digital display | No wall charger included |
| Charges multiple devices at once | Pricier than some competitors |
Power Bank, 27000mAh 140W USB C Laptop Portable Charger
This 27,000mAh power bank is a beast for high-capacity charging. The 140W USB-C output is a standout, delivering fast charging for laptops like the MacBook Pro and Dell XPS, as well as phones and tablets. I tested it with multiple devices at once, and it handled everything like a champ.
The built-in LED screen is a game-changer, showing real-time wattage and battery percentage. Despite its large capacity, it’s still relatively portable, though it’s a bit heavier than smaller models. The durable build and included charging cable make it a top choice for frequent travelers or professionals.
Pros & Cons:
| Pros | Cons |
|---|---|
| 140W fast charging | Slightly heavier due to capacity |
| Clear LED screen with real-time data | Bulkier than smaller models |
| Durable build and included cable | Price might be a bit steep |
Anker Power Bank, 20,000mAh Portable Charger with Built-in USB-C Cable
The Anker Power Bank is a reliable companion for fast, portable charging. Its 20,000mAh capacity and 87W max output make it ideal for laptops, phones, and tablets. The built-in USB-C cable is a standout feature—no more fumbling for extra cables!
During testing, it charged my MacBook Air from 10% to 50% in under 30 minutes, and the digital display kept me updated on the battery life. It’s slightly bulky, but if you prioritize convenience and reliability, this is a solid choice.
Pros & Cons:
| Pros | Cons |
|---|---|
| Built-in USB-C cable | A bit bulky and heavy |
| Fast charging (87W max) | Limited to 20,000mAh capacity |
| Digital display for battery life | Trickle charge mode can be finicky |
Portable Power Bank with AC Outlet, 100W Portable Laptop Charger
This power bank is a solid choice if you need a reliable backup power source for laptops and other devices. The 27000mAh capacity and 100W AC outlet make it versatile for business travel or outdoor activities. I tested it with my laptop and got an extra 5+ hours of work time—pretty impressive! The built-in flashlight and rugged design are nice touches, though the weight might be a drawback for some.
One standout feature is the 65W USB-C PD port, which charges laptops quickly. However, the AC outlet has some quirks—it struggles with polarized plugs and doesn’t ground properly, which could be a safety concern. Charging the power bank itself takes a while, and the included USB-C cable feels a bit flimsy. Still, it’s a great value for the price, especially if you need AC power on the go.
Pros & Cons:
| Pros | Cons |
|---|---|
| High capacity (27000mAh) | AC outlet has voltage issues |
| Includes 65W USB-C PD port | Heavy and bulky |
| Built-in flashlight | Long charging time |
