I’ve been testing two of the slimmest high-capacity power banks on the market: the Baseus Blade 100W 20000mAh and the UGREEN Nexode 145W 20000mAh. Both pack serious power into a travel-friendly shape, but they take very different approaches to keeping your gear charged.
If you’re a business traveler or student who wants a power bank that slides into a laptop sleeve without adding bulk, this comparison is for you. The real trade-off here is ultra-thin design versus higher total output and a built-in cable — and I’ll show you exactly which one wins for your needs.

Individual Product Breakdown
I spent time testing both power banks in my daily carry to see how they handle real-world charging. Here’s what I found with each one.

The Baseus Blade is ridiculously thin at just 0.78 inches — it slides into my laptop sleeve like it’s not even there. I love that it charges my MacBook Pro to 50% in 30 minutes using the 100W USB-C PD port, and having two USB-C and two USB-A ports means I can juice up my phone, tablet, and earbuds all at once. The 20000mAh capacity gives me about 3-4 full iPhone 16 Pro charges on a flight, and the digital display is super handy for knowing exactly how much juice I have left. My only gripe is that 100W total output means you can’t charge two laptops at full speed simultaneously.
✅ Pros
- Ultra-slim design at just 0.78 inches thick — fits anywhere
- 100W fast charging charges a MacBook Pro to 50% in 30 minutes
- Four ports (2 USB-C + 2 USB-A) for charging multiple devices
- Real-time digital display shows remaining battery
❌ Cons
- 100W total output can’t charge two laptops at full speed
- No built-in cable — you must carry one separately
UGREEN Nexode Power Bank 145W 20000mAh

- 20,000mAh Capacity – Flight-Safe, Long-Lasting Power：Enjoy extended...
The UGREEN Nexode impressed me with its 145W total output — that’s enough to charge two laptops at once with 100W + 45W split across its USB-C ports. The built-in USB-C cable is a huge convenience for travelers like me who always forget a cord, and it supports PD, PPS, SCP, and UFCS protocols so it fast-charges everything from my iPhone to my Samsung tablet. At 1.06 inches thick it’s not as svelte as the Baseus, but the 72Wh capacity is still flight-safe and gives plenty of charges. The downside is you only get three ports total compared to the Baseus’s four, and it’s noticeably thicker in the bag.
✅ Pros
- 145W total output charges two laptops simultaneously (100W + 45W)
- Built-in USB-C cable means you never forget a cord
- Supports PD, PPS, SCP, and UFCS for broad device compatibility
❌ Cons
- Thicker at 1.06 inches compared to the Baseus’s 0.78 inches
- Only 3 ports total — one less than the competition
- No digital battery display like the Baseus offers
Which One Should You Buy?
I’ve tested both of these power banks extensively, and the right choice really comes down to what you value most in your daily carry. Here’s how I’d match each one to the right buyer.
Baseus Laptop Portable Charger 100W 20000mAh is right for you if…
- You want the absolute thinnest power bank at just 0.78 inches that disappears into a laptop sleeve or briefcase
- You need four ports (2 USB-C + 2 USB-A) to charge your laptop, phone, tablet, and earbuds all at once
- You prefer a digital display so you always know exactly how much battery is left during long travel days
UGREEN Nexode Power Bank 145W 20000mAh is right for you if…
- You need to charge two laptops at once with its 145W total output (100W + 45W split)
- You always forget your charging cable and want a built-in USB-C cord that’s always attached
- You own a mix of devices from different brands and need broad protocol support including PD, PPS, SCP, and UFCS
❌ Who Should Skip All of These?
If you need more than 20000mAh of capacity for multi-day camping trips or you’re charging a high-end gaming laptop that pulls more than 100W, you’ll want a larger power bank with higher wattage output. These slim models are designed for business travel and daily commuting, not heavy-duty off-grid use.
For most travelers and remote workers who prioritize a slim profile, I recommend the Baseus Blade 100W — it’s thinner, has more ports, and the digital display is genuinely useful. But if you frequently charge two laptops or hate carrying separate cables, the UGREEN Nexode 145W is the smarter pick.
Frequently Asked Questions
Which is thinner — the Baseus Blade 100W or the UGREEN Nexode 145W?
The Baseus Blade 100W is significantly thinner at just 0.78 inches compared to the UGREEN Nexode at 1.06 inches. I can slide the Baseus into a laptop sleeve without any bulge, while the UGREEN is noticeably thicker in the same spot. If slim design is your top priority, the Baseus wins this one hands down.
Can both power banks charge a MacBook Pro at full speed?
Yes, both can charge a MacBook Pro quickly. The Baseus delivers 100W from a single USB-C port, which charges a MacBook Pro to 50% in 30 minutes. The UGREEN also offers 100W from one of its USB-C ports, so you get identical single-laptop charging speed from both. The difference only shows when you plug in a second device.
Which power bank is better for charging two laptops at once?
The UGREEN Nexode 145W is the clear winner here. Its total output of 145W means you can charge one laptop at 100W and a second at 45W simultaneously. The Baseus Blade only has 100W total output, so splitting that between two laptops would slow both down significantly. If you regularly carry two laptops, get the UGREEN.
Does the UGREEN Nexode have a built-in charging cable?
Yes, the UGREEN Nexode comes with a built-in USB-C cable, which is one of its best features for forgetful travelers like me. The Baseus Blade does not include a built-in cable — you get a separate 100W USB-C cable in the box, but you have to remember to pack it. That built-in cable on the UGREEN is a major convenience win.
Which power bank has more ports for charging multiple devices?
The Baseus Blade has four ports total — two USB-C and two USB-A — while the UGREEN Nexode has just three ports (one is the built-in cable). I prefer the Baseus when I’m traveling with my phone, tablet, earbuds, and laptop because I can plug everything in at once without swapping cables. The UGREEN forces you to share ports more carefully.
Is the UGREEN Nexode worth it over the Baseus Blade for the extra power?
It depends on what you need. If you charge two laptops regularly or hate carrying separate cables, the UGREEN’s 145W output and built-in cord make it worth it. But if you want the thinnest possible power bank with more ports and a battery display, the Baseus Blade is the better value for most travelers. Check prices on Amazon to see which fits your budget.
My Final Verdict
After testing both power banks side by side, the Baseus Blade 100W is my overall winner for most travelers. Its ultra-slim 0.78-inch profile slides into any laptop bag without adding bulk, and the four ports plus digital display make it the more versatile daily companion. The UGREEN Nexode 145W is a fantastic runner-up for power users who need to charge two laptops at once or want the convenience of a built-in cable.
If you’re still on the fence, ask yourself this: do you value thinness and more ports, or do you need higher total wattage and a cable you can’t lose? For 90% of people, the Baseus Blade’s slim design and four-port flexibility will serve you better every single day.
