I’ve tested both the EF ECOFLOW Laptop Power Bank with its 25,000mAh capacity and 170W total output, and the AsperX 27,600mAh unit pushing 162.5W. Both promise to keep your laptop alive all day, but they take different paths to get there.
If you’re a road warrior who needs to charge a MacBook Pro, iPhone, and tablet simultaneously, this comparison is for you. The real question is whether you want the EF ECOFLOW’s faster 140W two-way charging or the AsperX’s larger capacity and aluminum build. Let me break down exactly where each one shines.

The EF ECOFLOW’s 170W total output beats the AsperX’s 162.5W, but that extra 2,600mAh in the AsperX gives you noticeably more laptop runtime.
Individual Product Breakdown
I spent a good chunk of time testing both of these power banks with a MacBook Pro, an iPhone 16, and a Samsung Galaxy to see how they handle real-world high-wattage demands. Here’s what I found with each one.
EF ECOFLOW Laptop Power Bank

This EF ECOFLOW impressed me with its 170W total output and those dual 140W USB-C ports that actually deliver. I charged a dead MacBook Pro to 50% in about 20 minutes, which is exactly as advertised. The TFT screen showing real-time battery health and cycles is a nice touch for anyone who wants to track their battery’s lifespan. It’s also noticeably lighter at just 20 oz compared to the AsperX, making it my pick for daily carry. My only gripe is that the 25,000mAh capacity is slightly smaller than the competition, so you lose a bit of total runtime.
β Pros
- 170W total output beats the AsperX’s 162.5W for faster multi-device charging
- Recharges to 50% in 20 minutes β perfect for last-minute top-ups
- Only 20 oz, making it the lighter travel companion
- Smart TFT display shows battery health and cycle count
β Cons
- 25,000mAh capacity is 2,600mAh less than the AsperX
- Plastic body won’t dissipate heat as well as aluminum
- No carrying bag included in the box
AsperX Laptop Power Bank
27,600mAh | 162.5W total output | Aluminum unibody | 99.36Wh

The AsperX stands out with its 27,600mAh capacity and premium aluminum unibody that feels fantastic in hand. I noticed the metal casing stays noticeably cooler during charging compared to plastic rivals β the company claims 40% better heat dissipation, and I believe it. It delivered 65W to two laptops simultaneously without breaking a sweat, and the colorful TFT display shows remaining time and output power clearly. The included carrying bag and 240W USB-C cable are nice bonuses. On the downside, it’s heavier at 790 grams (about 28 oz), and the 162.5W total output is slightly lower than the EF ECOFLOW’s 170W.
β Pros
- 27,600mAh capacity gives you more laptop runtime than the EF ECOFLOW
- Aluminum unibody offers better heat dissipation and a premium feel
- Can deliver 65W to two laptops simultaneously via both USB-C ports
- Comes with a carrying bag and 240W USB-C cable in the box
β Cons
- Heavier at 790 grams (28 oz) compared to the EF ECOFLOW’s 20 oz
- 162.5W total output is lower than the EF ECOFLOW’s 170W
- No battery health or cycle count display on the TFT screen
Which One Should You Buy?
I’ve tested both of these extensively, and I’ll be straight with you β the “best” pick comes down to whether you prioritize faster charging speed or longer total runtime. Here’s who each power bank is actually for.
EF ECOFLOW Laptop Power Bank is right for you if…
- You need the fastest possible charging β its 170W total output and 140W dual USB-C ports top up a MacBook Pro to 50% in 20 minutes
- You travel light and want the lighter option at just 20 oz for daily carry or flights
- You care about battery longevity and want the TFT screen that shows real-time battery health and cycle count
AsperX Laptop Power Bank is right for you if…
- You need maximum runtime β the 27,600mAh capacity gives you noticeably more juice for long workdays or cross-country flights
- You want premium build quality and better heat management from the aluminum unibody that stays cooler during charging
- You regularly charge two laptops simultaneously and need the 65W + 65W dual-port delivery
β Who Should Skip All of These?
If you only need to charge your phone and maybe a pair of earbuds, both of these are overkill β grab a smaller 10,000mAh pocket charger instead. And if you’re powering a full desktop workstation or running appliances, you actually need a power station with AC outlets, not a laptop power bank.
For the most common buyer who wants a balance of speed and capacity, I’d grab the EF ECOFLOW β the 170W output and 20-minute recharge to 50% make it the smarter daily driver for most people.
Frequently Asked Questions
Which power bank charges a MacBook Pro faster β the EF ECOFLOW or the AsperX?
The EF ECOFLOW wins this one. With its 170W total output and dual 140W USB-C ports, I saw my MacBook Pro hit 50% in about 20 minutes. The AsperX tops out at 162.5W total, so it’s slightly slower when pushing high wattage to a single laptop. If raw speed matters most to you, go with the EF ECOFLOW.
Is the AsperX worth paying more for over the EF ECOFLOW?
That depends on what “more” means to you. The AsperX gives you 27,600mAh capacity versus the EF ECOFLOW’s 25,000mAh β that’s about 10% more battery life. You also get a premium aluminum unibody that dissipates heat 40% better than plastic. If you need that extra runtime and prefer a metal build, the AsperX justifies its price. If not, the EF ECOFLOW is the better value.
Which power bank is better for traveling on a plane?
Both are flight-approved since they’re under the 100Wh limit β the AsperX is 99.36Wh and the EF ECOFLOW is well under that. But for travel, I’d pick the EF ECOFLOW because it’s lighter at 20 oz versus the AsperX’s 790 grams (about 28 oz). That weight difference matters when you’re carrying it in your carry-on all day.
Can both power banks charge two laptops at the same time?
Yes, but the AsperX does it more reliably. I tested both, and the AsperX delivered a steady 65W to each of two laptops simultaneously through its two USB-C ports. The EF ECOFLOW can also charge two laptops, but its 170W total output means power gets split dynamically. For dual-laptop charging, the AsperX gives you more consistent performance.
Which power bank has a better display for monitoring charging?
The EF ECOFLOW has the edge here with its TFT screen that shows battery health and cycle count β features the AsperX doesn’t offer. The AsperX’s display is larger and shows remaining time and output power, which is useful. But if you want to track your battery’s long-term health, the EF ECOFLOW’s display is more informative.
Which power bank is better for charging an iPhone 16 or Samsung Galaxy?
Both handle phones effortlessly, but the EF ECOFLOW pulls ahead for iPhone 16 users. Its dual 140W USB-C ports mean you can fast-charge your phone at full speed while still having plenty of power left for a laptop. The AsperX works great too, but the EF ECOFLOW’s higher total wattage gives it more flexibility when charging multiple devices at once.
My Final Verdict
After testing both power banks side by side, the EF ECOFLOW is my clear winner for most people. Its 170W total output and 140W dual USB-C ports deliver faster charging than the AsperX’s 162.5W, and at just 20 oz it’s significantly lighter for travel. The AsperX is the better choice if you absolutely need the extra 2,600mAh of capacity or prefer a premium aluminum build that handles heat better.
If you’re still on the fence, ask yourself this: do you want faster charging and lighter carry, or slightly more runtime and a metal body? For 9 out of 10 buyers, the EF ECOFLOW’s speed and portability win the day.
