INIU 140W Power Bank 25000mAh High Capacity Portable Charger USB C in Out Smart Display

This INIU 140W 25000mAh Power Bank arrived very well packaged, and came with with a 24-inch long USB-C to USB-C charging cable (no charger) and a concise, fanfold, 10 language user manual. No storage bag was included for travel. The charger has a gray, matte, plastic finish, which despite other reviewer's comments, is not fingerprint immune, just muted. But the surface is not the rubberized kind of material that can become tacky over time. The sides of the rectangular profile are rounded enough to prevent resting it on any of it's edges. The bottom of the unit is not cushioned to prevent sliding on a smooth surface, but that's not a big deal. It features three ports, two USB-C and one USB-A. C1:IN/OUT is the dual purpose USB-C port for both charging input (80W max) and output (140W max). C2:OUT has a 45W max output, and A:OUT has an 18W max output. The unit arrived with a 60% charge and took about 45 minutes to fully charge using a 5V/3A charger. When discharged to 80%, a 65W GaN charger took 21 minutes to fully charge it again. When discharged to 19% during testing, it became fully charged within 1 hour, 9 minutes with the 65W GaN charger. During charging, the power bank stayed cool, whereas the 5V/3A charger became a bit hot, while the 65W GaN charger only became warm. Pressing the button on the upper right side of the unit illuminates the percent charge in green digits (EZ Mode). When plugged in (for charging or discharging), long pressing the button for 3 seconds alternates between EZ Mode and Pro Mode. I like that in "Pro" mode, the digital display shows three numbers; wattage in/out (blue digits), percent charge on the power bank (green digits), and time remaining for both charging input and output (blue digits). That display stays illuminated about one minute before turning off. I acquired this power bank for several reasons: - I live in an area that experiences occasional power outages, usually due to either extreme cold or heavy storms, including hurricanes. - I previously acquired a different INIU 20,000mAh power bank which came in very handy during a subsequent power outage (hurricane). I had charged that INUI unit and two other power banks (different brands) to 100% months prior to needing them, then forgot about them. When I lost power, I discovered that one of the other power banks had discharged completely to 0%, which didn't surprise me because I had encountered other problems (over heating when charging) with that power bank previously. However, the INIU and another unit still retained a 100% charge. So, I grew to trust the INIU brand, and it helped me keep my cell phone charged, while also helping to run a rechargeable fan and LED lights. - Besides using this unit to charge my phone and other accessories, the primary reason I got this INIU unit was to charge my laptop as needed. My laptop (Dell XPS 17 9720) has a 8071mAh battery that requires a 130W charger, so I was attracted to this units 140W max output as well as it's hefty 25000mAh power reserve. However, when I plugged it into my laptop it only fluctuated between 29.1 to 87.2 max wattage output, mostly hovering closer to 58W, and my laptop battery signaled "Weak charging stage, please check power charger." I was disappointed that this INIU power bank is inefficient for what I wanted it to do. Trying to understand why, it was noteworthy that the specifications in the INIU user manual indicated that max output to achieve 140W is 28V/5A. However, the AC adapter for my laptop has an output spec of 20V/6.5A to reach 130W, so perhaps the amperage output of this INIU unit is too low to most efficiently charge my laptop - just speculating. That's not to say it didn't charge my laptop, it certainly did. Using it to charge my laptop WHILE IT WAS RUNNING, brought it from 57% to 99% over the course of 1+ hours, but drained the power bank from 100% to 19%. I should mention that my laptop battery's drainage fluctuates between 21% and 79%, so the INIU charger did a good job of keeping up. During that time, my laptop's battery monitor indicated a charging rate of around 20%/hour, slowly decreasing to 12%/hour as the INIU unit drained and the laptop battery filled. I hibernated my laptop to test the INIU's wattage output to it, which was around 43.1W. When I turned my laptop on again the INIU wattage output jumped up, fluctuating between 60W to 87.9W. In Pro Mode, there was an apparent discrepancy between "charge time remaining" as stated by the INIU charger versus my laptops battery monitor, with the INIU unit predicting a much longer charge time. I also noted when re-charging the INIU unit (from 19%) that it's "charge time remaining" was inaccurate, with it charging faster (with a 65W GaN charger) than the unit stated. During charging, the wattage input closely matched the charging adapters being used, albeit slightly lower. Despite never witnessing 140W output from this INIU power bank to charge my laptop, it is still valuable to keep various devices charged as needed. I encountered no problem with it super-fast charging my Galaxy S22 Ultra, and expect it could charge it many times over. During my testing, it held it's charge, and never overheated, so I expect I can rely upon it when needed. I could easily recommend this INIU power bank. Read more

This big battery has plenty of juice for charging multiple electronics at once. In addition, it takes a while to run down, so you can even plug your computer into it and not have to worry about it declining as quickly. It’s a hig battery and therefore takes up more space than the smaller versions. It would be good for slipping into a purse or computer bag, but a bit to large for carrying in one’s pocket. My husband has utilized this item the most, but with its multiple ports and ability to sustain multiple devices. It has come in really handy. Read more

My husband often works in remote areas where he's away from a way to charge his phone for several hours. There are plenty of lighter weight power banks on the market, but he needs something that carries enough juice to charge not only his iPhone but his emergency satellite phone as well (he's often in areas with zero cell coverage). This power bank allows him to do both. Neither device has shown any compatibility issues to where the device will not charge when plugged into this power bank. His only big concern with using this charger is how his work-issued ACER laptop would one day recognize this charger but the next said it was incompatible. Since this charger has no trouble when charging his iPhone, iPad, watch, or satellite phone, he's still very pleased with the charging performance. Any other issue is just little things, such as the weight and lack of carry pouch to keep dirt and debris out of the ports. He is quite impressed with the LED display and the information it supplies. So many portable chargers don't show you how much power the bank still contains. No one wants to get stuck with drained power bank when you need one during an emergency. Read more

This portable battery charger has seriously impressed me. The input and output wattage are incredibly fast, which was a major reason I bought it. I use it to charge my phone, Apple Vision Pro, and even my laptop—and it handles all of them beautifully thanks to the high wattage output. It really pushes your devices to charge at their max speed, which is exactly what I was looking for. Now, it’s a 27,000mAh battery, so yes—it’s hefty. But it’s not unmanageable at all. You can easily toss it into a backpack, and while it’s large enough to notice, you can still hold it in one hand without feeling overwhelmed. I was prepared for the size and weight, and I found that it’s totally reasonable for the capacity it offers. One of my favorite features is the LCD readout. It’s crystal clear and shows both the wattage the power bank is charging at and the wattage it’s outputting to your devices. This has been super useful in helping me figure out which of my USB-C cables are actually high-speed and which ones are slowing me down. It’s saved me time by identifying the cables that need upgrading for faster charging. The packaging was another pleasant surprise—it’s sustainably sourced and feels premium. The charger itself feels robust and very well-built, with a sturdy, quality design that gives you confidence it will last. Yes, it’s on the pricier side at $100, but for the level of performance it offers, it’s completely worth it. If you can catch it on sale, even better—but I’d honestly buy it again at full price without hesitation. If you need a portable charger that can handle everything, this one’s a powerhouse. Read more
