INIU 25000mAh 140W Review: Budget Laptop Charging That Actually Works

The INIU 25000mAh 140W power bank shouldn’t be this good at $50. It charges laptops at 140W, holds 90Wh of capacity, and includes an LED display — features that typically cost $100 or more from Anker and Baseus. If you’re on a budget, this is the one to watch.

Key Specs at a Glance

• Capacity: 25,000mAh / 90Wh
• Max Output: 140W USB-C
• Ports: 2x USB-C, 1x USB-A
• Features: LED display, pass-through charging
• Weight: 1.1 lbs

Who Is It For?

Students, budget-conscious remote workers, and anyone who wants laptop charging capability without spending $100+. If you need a power bank for occasional laptop top-offs and daily phone charging, the INIU delivers the essentials at half the price of premium brands.

140W at $50 Is Absurd Value

Let’s be clear about what this means: you get the same 140W PD 3.1 USB-C output found in the Anker 737 ($110) and Baseus Blade 2 ($100) for literally half the price. In our testing, the INIU successfully charged a MacBook Pro 14-inch at full speed. The LED display shows battery percentage, wattage, and remaining time. Pass-through charging lets you charge the power bank and your devices simultaneously. These are not budget-tier features.

The Capacity Advantage

At 90Wh (rated), the INIU matches the Ugreen Nexode and edges out the Anker 737’s 87Wh. That’s enough for roughly one full MacBook Air charge or about 3-4 full phone charges. It also slips under the FAA’s 100Wh carry-on limit.

The Trade-offs

You can feel the price difference in the build. The plastic housing flexes slightly under pressure, and the overall fit and finish doesn’t match Anker’s or Baseus’s premium feel. The USB-A port lacks Quick Charge support. And in our testing, real-world capacity came in slightly below the rated 25,000mAh — closer to 23,000-24,000mAh of usable power. That’s a common issue with budget power banks, but worth noting when comparing specs.

The Bottom Line

The INIU 25000mAh 140W is the best budget laptop power bank you can buy. The build quality won’t impress anyone, and you’ll lose a bit of rated capacity, but 140W output at $50 is a value that the premium brands simply can’t match. If your budget is firm, buy this without hesitation.
