Cap = 12,000mAh - So far so good on power, like the size, and for the value, not bad when it is on sale. But when it is not on sale, it's kinda steep. I did do a battery test on it, it was fast to charge up since I use a 100W GAN outlet charger. It is easy to use, and very portable. Love the design versus a big lunky thing. The test I did with this was to fully charge to 100%, then use my tester to match the output of the Output 3 or USB-A settings and let it rip. Though the battery is rated at 20,000mAh, the actual capacity the user will get is 12,065mAh. It would be higher if the display was able to go off and not stay on 24/7 while depleting. Because I assume that takes some of the charge. Also, my little tester does take a bit more from the charge because it has it's own LCD screen, but I can control the voltage coming from the device. Took about 4-5 hrs to fully charge this thing, not bad. and 4 hours to fully deplete. You can see from the photos, about 1hr 35min in, it was from 100% down to 57%, very quick depletion, however took long time to get down to full depletion, at 4hrs 4min. And for those seeing Watts per hour.. there you go 60Wph, incase you are flying, that is Low for the travel. I plan on buying another one before my travel as a gift. Review: Solid power pack with Wh stated clearly on it for airline security compatibility - I bought this because I needed a power pack that definitely had the TSA Wh measurement printed on it (so many others don't) so no matter who I encountered in airplane security, it would be clear that my power pack was within legal limits. This is important if you're flying to a destination where you'll need to use that battery pack to trek with. Something to note is that "100W" doesn't mean "100Wh", which is the limit you have to stay at or under without getting special permission. So many other units are sold in terms of Watts, which is a descriptor of how much power they can deliver through those ports, not how much energy they can store (which is battery Volts x Amps x hours). Also, I wanted a power pack that showed how much battery was really left. I have purchased other packs with just a few LED dots that indicated power level, but these seemed to serve more as decoration or entertainment than as factual readings. This INIU power pack's digital capacity display definitely shows how much is left, and it seems to discharge linearly when loads being charged are actually drawing power continuously. It behaves like a power pack that is 67Wh in capacity (so many on the market have a rating that makes it possible for them to do that, but the batteries inside them don't actually have that capacity). This unit is smaller than an iPhone (about 3/4 of the length, slightly narrower, though twice as thick). It has solid construction and only one button (on/off); very nice. It is UNUSUALLY HEAVY, weighing 11.6oz on my lab scale. For comparison, a medium-sized iPhone pro weighs 8.5oz, making the power pack weigh 35% more than the phone. While I am buying this for trekking because of its size, dependability, and air travel compatibility, it is going to add a half pound to my pack (not suitable for backpacking, in my view). The power pack easily powered up an iPhone with the USB-C cable in a couple hours on the medium charge rate (there are three power ports to choose from), leaving room enough for about two more of those plus a headlamp charge. Again, ideal for trekking to stay in touch. I would recommend this power bank for trekking and certainly for air travel where you need to be certain that anyone could read the printed details on the back of the power pack, providing its real Wh and other characteristics. The unit does not get hot at all while charging. ## Features - Wallet-Sized Laptop Power Packs a massive 20,000mAh into a body smaller than a standard wallet.

Choose a power bank based on your laptop’s max input and daily workload. **Q: Can a Laptop Power Bank Damage My Laptop Battery?** A: No, if you pick a high-quality, compatible power bank with proper voltage regulation and USB-C PD support. Low-quality or unstable power banks can wear the battery over time. Always choose certified power banks with protections. **Q: Why Does My Power Bank Provide Fewer Charges Than Expected?** A: External batteries typically deliver 60%-70% of their rated capacity. 30%-40% is lost to heat from voltage conversion and circuitry, which reduces the number of full charges for your device. **Q: How to Calculate the Possible Number of Charges?** A: Formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges. Example: (20000mAh × 0.65) ÷ 3692mAh ≈ 3.5 charges for iPhone 17. **Q: Does It Support Pass-Through Charging?** A: Yes. The power bank supports pass-through charging, allowing you to charge the power bank and connected devices at the same time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not bad for 4hr depletion time.

Unfortunately, it stopped charging in August. Since the power bank comes with a 3-year warranty, I contacted INIU customer support. Their response was outstanding. A special thank-you to Karlin, who was incredibly helpful throughout the process! They first provided clear troubleshooting instructions to see if the problem could be resolved. When those steps didn’t work, they immediately sent me instructions for returning the defective charger, along with a postage-paid return label. What really impressed me: just 24 hours after I dropped off the defective unit, I had a brand-new replacement charger. Products can occasionally fail—that happens with any manufacturer. What separates a great company from the rest is how it handles things when something goes wrong. INIU’s customer service and warranty support were exceptional: fast, easy, professional, and hassle-free. This level of customer support gives me confidence in buying INIU products again.
