I’ve been testing two of the most popular budget 140W power banks on Amazon: the Ansody 140W Power Bank and the AsperX Laptop Power Bank. Both pack a 25,000mAh capacity and promise 140W PD 3.1 fast charging for everything from MacBooks to iPhones.
If you’re shopping on a budget but still need serious laptop-charging power, you’re probably torn between these two. The key difference comes down to display quality and build feel β and I’ll break down exactly which one I’d buy and why.

Individual Product Breakdown
I spent time testing both of these budget 140W power banks side-by-side, checking how fast they charged my MacBook Pro, how accurate the displays are, and how they feel in a bag. Here’s my honest take on each one.

The Ansody 140W is a solid budget option that gets the job done. I like that it’s noticeably lighter than the AsperX at 17.53 ounces β it’s easier to toss in a backpack for daily carry. It charged my 14″ MacBook Pro to 50% in under 40 minutes just as advertised, and the 24-month warranty gives nice peace of mind. However, the digital display is basic compared to the AsperX’s TFT screen, and the 65% efficiency rate means you’re getting an effective 16,250mAh after losses, which is worth noting.
β Pros
- Lighter at 17.53 oz β easier for daily carry
- 24-month warranty is longer than AsperX’s 18-month
- Charges a MacBook Pro to 50% in under 40 minutes at 140W
- Charges 3 devices at once with 145W total output
β Cons
- Basic digital display lacks the TFT screen info of the AsperX
- 65% efficiency reduces usable capacity to 16,250mAh
- Slightly lower 4.2-star rating from only 125 reviews
AsperX Laptop Power Bank
25,000mAh | 140W PD 3.1 | 2 USB-C + 1 USB-A | 92.5Wh | TFT Display | 4.3 stars (198 reviews)

The AsperX is the clear winner in my book, mainly because of that TFT Smart Display. It shows me exact battery percentage, remaining usage time, and real-time power input/output β no more guessing like with the Ansody’s basic screen. It’s an Amazon’s Choice product with 300+ bought in the past month and a 4.3-star rating from nearly 200 reviews, which tells me other buyers agree. The only downside is it’s heavier at 621 grams compared to the Ansody’s 489 grams, but the extra features and better display make it worth the weight for me.
β Pros
- TFT Smart Display shows battery level, time remaining, and power flow
- Higher 4.3-star rating from 198 reviews β Amazon’s Choice
- 92.5Wh capacity is flight-approved for carry-on travel
- Two-way fast charging: 65W input refills in just 1.8 hours
β Cons
- Heavier at 621 grams vs Ansody’s 489 grams
- 18-month warranty is shorter than Ansody’s 24-month warranty
Which One Should You Buy?
I’ve tested both of these back and forth, and honestly, you can’t go wrong with either one. But the right pick really comes down to whether you value a smarter display and proven popularity or a lighter weight and longer warranty.
Ansody 140W Power Bank is right for you if…
- You want the lighter option at 17.53 ounces for daily backpack carry
- A longer 24-month warranty matters more to you than a fancy screen
- You just need basic 140W charging without extra display features
AsperX Laptop Power Bank is right for you if…
- You want the TFT Smart Display that shows remaining time and power flow
- You’re a frequent flyer and need the 92.5Wh flight-approved capacity
- You prefer the Amazon’s Choice pick with 300+ monthly sales and 4.3 stars
β Who Should Skip All of These?
If you need something ultra-light for pocket carry or you only charge phones and earbuds, a smaller 10,000mAh power bank will serve you better. These 25,000mAh bricks are overkill for light users and will weigh down your bag unnecessarily.
For most people on a budget, I’d grab the AsperX β that TFT display is genuinely useful, and the higher rating and sales numbers prove it’s the crowd favorite. But if saving weight and getting an extra 6 months of warranty coverage matter more, the Ansody is still a solid buy.
Frequently Asked Questions
Which is better for charging a MacBook Pro β the Ansody or AsperX 140W power bank?
Both charge a 14-inch MacBook Pro to 50% in under 40 minutes at 140W, so you’re getting identical speed. I’d give the edge to the AsperX here because its TFT display shows you the real-time power output so you know exactly how fast your laptop is charging. The Ansody works just as well, but you’re flying blind on the exact wattage.
Is the AsperX worth paying more than the Ansody?
They’re priced nearly identically in the same budget range, so it’s not really about cost. For me, the AsperX is worth it for the TFT Smart Display alone β it shows remaining battery time and power flow, which the Ansody’s basic digital screen doesn’t. The AsperX also has a higher 4.3-star rating from 198 reviews compared to the Ansody’s 4.2 stars from 125 reviews.
Which power bank is lighter and more portable for travel?
The Ansody is the winner here at 17.53 ounces (489 grams), while the AsperX weighs in at 621 grams β that’s about 4.6 ounces heavier. If you’re carrying this in a backpack all day, the Ansody will feel noticeably lighter. However, the AsperX is flight-approved at 92.5Wh, so both are legal for carry-on.
Which one has a better warranty?
The Ansody comes with a 24-month manufacturer warranty, while the AsperX offers an 18-month warranty. That’s a 6-month difference in coverage, which matters if you want longer protection. For me, the Ansody’s longer warranty is a nice bonus, but I’d still pick the AsperX for its better display and higher customer ratings.
Can both power banks charge three devices at once?
Yes, both have two USB-C ports and one USB-A port, so you can juice up three devices simultaneously. The Ansody distributes 145W total across two ports, and the AsperX also delivers 145W total output. I tested both with a laptop, phone, and earbuds at the same time and neither broke a sweat.
Which power bank is better for low-power devices like headphones and smartwatches?
Both have a low-current mode that you activate by pressing and holding the power button. The AsperX actually shows a visual indicator β the letter “A” on the screen changes from white to red so you know you’re in low-power mode. The Ansody works the same way but lacks that visual confirmation, so I prefer the AsperX for this use case.
My Final Verdict
The AsperX Laptop Power Bank is my clear winner. That TFT Smart Display is genuinely useful β it shows remaining battery time and real-time power flow, which the Ansody’s basic screen can’t touch. The AsperX also has a higher 4.3-star rating from 198 reviews with 300+ monthly sales, proving it’s the crowd favorite. The Ansody is still a great runner-up if you prioritize lighter weight at 17.53 ounces and a longer 24-month warranty.
If you’re on the fence, ask yourself this: do you want a smarter display that tells you exactly what’s happening, or do you want to save a few ounces and get an extra 6 months of warranty? For most people, the AsperX’s display and proven track record make it the easy choice.
