If you’re hunting for a slim power bank that won’t bulge in your bag but still packs enough juice for a laptop, you’re probably stuck between the UGREEN Nexode, the Baseus Blade, and the Anker Prime 25000. They all promise big power in a travel-friendly shape, but their thickness and total output are wildly different.
I tested these three side-by-side to figure out which one actually fits in a laptop sleeve and which one charges the fastest. One of them surprised me by being both the slimmest and the most practical for daily carry β let me show you which.

Individual Product Breakdown
I spent time testing each power bank’s thickness, output speed, and real-world portability to see which slim profile charger actually delivers on its promises. Here’s what I found with each one.
UGREEN Nexode Power Bank

- Dual USB-C Charging β Two Laptops, One Power BankοΌWith one built-in...
- 20,000mAh Capacity β Flight-Safe, Long-Lasting PowerοΌEnjoy extended...
The UGREEN Nexode packs a punch with 145W total output, which is the highest of all three power banks here. I love that it has a built-in USB-C cable and an extra 45W USB-C port so you can actually charge two laptops at the same time β a real productivity boost. At 1.06 inches thick, it’s not the slimmest option, but it’s still easy to toss in a briefcase. If you’re a business traveler who needs to power a MacBook Pro and a tablet simultaneously, this is your best bet.
β Pros
- 145W total output β highest of the three for charging two laptops
- Built-in USB-C cable means no extra cord to carry
- 72Wh capacity is flight-safe for carry-on travel
- Supports PD, PPS, SCP, and UFCS fast-charging protocols
β Cons
- Thickest of the three at 1.06 inches
- Only 3 ports total, fewer than the Baseus Blade
- No digital display for battery percentage

The Baseus Blade is the thinnest power bank of the bunch at just 0.78 inches, and it honestly feels like a slim notebook in your hand. I really appreciate the digital display that shows remaining battery in real-time, which takes the guesswork out of charging. It has four ports β two USB-C and two USB-A β giving you the most flexibility for charging older devices. The trade-off is that its total output caps at 100W, so you won’t be charging two laptops at full speed like the UGREEN can.
β Pros
- Thinnest design at 0.78 inches β slides into any bag pocket
- 4 ports total (2 USB-C + 2 USB-A) for maximum device compatibility
- Digital display shows exact remaining battery percentage
- Charges a MacBook Pro to 50% in 30 minutes
β Cons
- Only 100W total output β can’t charge two laptops at full speed
- No built-in cable, so you’ll need to carry your own
- Customer rating of 4.4 is the lowest of the three

The Anker Prime 25000 is the most complete package here with 25,000mAh capacity and three 100W USB-C ports, meaning you can charge three laptops at full speed simultaneously. I’m a huge fan of the dual built-in cables β one retractable up to 2.3 feet and another that doubles as a carrying strap β which makes it feel like an all-in-one travel solution. It’s also the most popular choice with over 10,000 purchases last month and a 4.5-star rating from nearly 9,000 reviews. The downside is that at 1.93 inches thick, it’s noticeably chunkier than the Baseus Blade, so it won’t disappear into a slim pocket as easily.
β Pros
- 25,000mAh capacity β highest of the three, charges laptops multiple times
- Triple 100W USB-C ports for charging three laptops at full speed
- Two built-in cables, including a retractable one up to 2.3 feet
- Recharges to 30% in just 22 minutes
β Cons
- Thickest at 1.93 inches β won’t fit in ultra-slim pockets
- Heaviest at 1.31 pounds, noticeable in a bag
- No USB-A port for older accessories
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to whether you prioritize pocket-friendliness, raw power, or maximum portability. Let me break down exactly who each one suits best.
UGREEN Nexode Power Bank is right for you if…
- You need to charge two laptops at once using the 100W + 45W dual output and the built-in USB-C cable.
- You’re a business traveler who wants a flight-safe 72Wh pack that fits in a briefcase without extra cords.
- You own devices from multiple brands and need broad protocol support including PD, PPS, SCP, and UFCS.
Baseus Laptop Portable Charger (Blade) is right for you if…
- You want the slimmest possible power bank at just 0.78 inches thick that disappears into a laptop sleeve.
- You need four ports (2 USB-C + 2 USB-A) to charge a mix of modern laptops and older phones or accessories.
- You prefer a digital display that shows exact remaining battery so you never get caught off guard.
Anker Laptop Power Bank (Prime 25000) is right for you if…
- You want the highest capacity at 25,000mAh and three 100W ports to charge three laptops at full speed.
- You hate carrying extra cables and want two built-in cords, including a retractable one that extends 2.3 feet.
- You need ultra-fast recharging β this pack hits 30% in just 22 minutes when you’re between flights.
β Who Should Skip All of These?
If you only need to charge a phone once or twice and never carry a laptop, you’re paying for way more power than you’ll use. A smaller 10,000mAh power bank or a wall charger with a built-in cable will save you weight and cash.
For most people who travel with a laptop and want a slim profile, I’d grab the Baseus Blade for its incredible 0.78-inch thickness and four-port flexibility β it’s the easiest to live with every single day. But if you need the most power and don’t mind the extra bulk, the Anker Prime 25000 is the clear winner with triple 100W ports and built-in cables.
Frequently Asked Questions
Which is slimmer: the UGREEN Nexode or the Baseus Blade?
The Baseus Blade wins easily here at just 0.78 inches thick, while the UGREEN Nexode measures 1.06 inches. That’s a 27% difference in thickness, and you’ll absolutely feel it when sliding them into a laptop sleeve or passport pocket. If slimness is your top priority, the Baseus Blade is the clear choice.
Is the Anker Prime 25000 worth the extra money over the UGREEN Nexode?
I think it is if you need the extra capacity and port count. The Anker gives you 25,000mAh versus the UGREEN’s 20,000mAh, plus three 100W USB-C ports compared to the UGREEN’s two ports with a 145W total output. You also get two built-in cables with the Anker versus one with the UGREEN, so if you regularly charge multiple laptops, the Anker justifies the higher price.
Can the Baseus Blade charge a MacBook Pro as fast as the UGREEN Nexode?
No, it can’t. The Baseus Blade tops out at 100W total output, while the UGREEN Nexode delivers 145W total and can push 100W to a single port. That means the UGREEN will charge a MacBook Pro noticeably faster, especially if you’re also charging a second device at the same time. For single-laptop charging, both are fine, but the UGREEN has more headroom.
Which power bank is best for flying with a slim bag?
All three are flight-safe since they’re under the 100Wh airline limit β the UGREEN is 72Wh, the Baseus is 72Wh, and the Anker is also compliant. But for a slim bag, the Baseus Blade at 0.78 inches thick is the easiest to tuck into a personal item or laptop compartment. The Anker at 1.93 inches is nearly two and a half times thicker, so it’ll eat up more space.
How many devices can each power bank charge at once?
The UGREEN Nexode charges up to 3 devices using its two USB-C ports and one built-in cable. The Baseus Blade handles 4 devices with two USB-C and two USB-A ports. The Anker Prime 25000 can charge up to 4 devices as well, thanks to its two built-in USB-C cables, one extra USB-C port, and a USB-A port. If you need to charge older accessories that use USB-A, the Baseus is your best bet.
Which power bank has the highest total wattage output?
The UGREEN Nexode leads here with 145W total output, which lets you charge a laptop at 100W and a second laptop at 45W simultaneously. The Anker Prime 25000 comes next with 165W total output across its ports, but each port is capped at 100W. The Baseus Blade is the lowest at 100W total, so it’s best for charging one laptop at full speed plus a phone or tablet.
My Final Verdict
The Anker Prime 25000 is my overall winner because it packs the most capacity at 25,000mAh, three 100W ports for charging multiple laptops, and two built-in cables β all in a flight-approved design. The Baseus Blade takes the runner-up spot for anyone who absolutely needs the thinnest profile at just 0.78 inches and four ports for older devices. The UGREEN Nexode is a solid third for business travelers who want 145W total output and a built-in cable, but its 1.06-inch thickness and lack of a digital display hold it back.
If you’re still on the fence, ask yourself this: do you want the slimmest possible power bank that disappears into a bag, or do you want the most power and ports for a full laptop setup? The Baseus Blade wins for pocketability, but the Anker Prime 25000 wins for raw capability.
