Pros and Cons
| Pros | Cons |
|---|---|
| 140W EPR charging support | One usable USB-C port |
| Nice performance | Hard-to-read display |
| Free carrying bag | Heavy |
| Expensive |
We’ve tested a lot of battery banks. Some claim sky-high speeds. Others try to win on capacity or size. But the INIU 140W Power Bank stands out for better and worse. With a claimed 140W EPR output, this power bank is built for serious charging. So we ran it through every test we had: discharge rates, recharge speed, thermal performance you name it. Here’s how it stacked up.
Design
This power bank is rated at 25,000mAh (or 92.5Wh), and it shows. It weighs nearly 500g, which definitely puts it in the “laptop power user” zone. You get two USB-C ports and a USB-A port, but here’s where things get weird: only one USB-C port supports input charging, and that’s the same one that pushes 140W EPR output. The other USB-C port is capped at 65W and doesn’t even let you recharge the unit. What in the USB-C hell is that?
The case has a smooth finish, albeit a bit greasy, and the digital display feels like an afterthought. The numbers are thin and hard to read, which doesn’t inspire confidence when you’re dealing with high-wattage charging.
Performance
INIU 140W can move serious power. In our testing, it hit a peak output of 140W, and it supports a wide range of PDOs including 15W, 27W, 45W, 100W, and even EPR up to 140W. It also supports PPS at 5A, ranging from 3V to 21V. Our tests showed a Fixed PDO SAVA score of 90.9% and a PPS score of 79.8%, making it one of the better PPS performers in our test group.
Efficiency, though? That’s where things slide a bit. We pulled 60.77Wh in a discharge test, against the stated 92.5Wh capacity, which gave us a total efficiency of 65.7%. That’s not terrible, but it’s not amazing either.
Thermals
Thermals were average. It was not bad but not fantastic either. Discharge temperatures peaked at 43.3°C and recharge temps topped out at 45.4°C. In a world where some power banks get uncomfortably hot, this one ran cooler than expected. That’s a good sign for longevity and safety.
Value
Here’s the deal: the INIU 140W costs around $81, which works out to about $0.75 per watt-hour. That’s on the expensive side. But for that price, you’re getting a bank that can legitimately charge a monster laptop or fast-charge multiple devices in a pinch. Recharge speed is where it shines: it fully recharged in under 90 minutes, which is the fastest we’ve tested so far.
INIU also throws in a carrying bag, and of the three INIU products we recently tested, this one was the clear winner. It’s the most refined and future-proof of the bunch.
Verdict
If you’re looking to future-proof your charging setup, this might be the power bank to beat especially if you’ve got power-hungry devices. Yes, it’s pricier, heavier, and not the most elegant piece of tech. But in terms of raw power, recharge speed, and PPS support, the INIU 140W holds its own. Just be ready to overlook the awkward port design and that hideous screen. For spec-driven users, this one’s a sleeper hit.
