(18 month update) - *** 18 month update *** This is still going strong. I frequently use this with my laptop ... I can get an additional 75% on my asus with this. It's really great if there's not a convenient outlet. It is limited to 45W when charging, but it can provide 65W to my laptop, so I can use this to do a quick power-up and then I can plug it in to the wall charger once it's discharged. It can fully recharge pretty quickly, so by the time my laptop is back down to maybe 75% it's generally ready to go again. Also works great powering my starlink mini dish. The starlink requires between 20 and 40W depending on conditions, so it can usually last a good long while. Still very pleased. *** original review *** I've been through one full discharge cycle on my laptop, and wanted to post my results. I monitored the entire cycle with a usb-c meter. The voltage was rock-solid at 19.4V, right up to full discharge. And it achieved a whopping 67.7WH! Using the standard li-ion cell voltage of 3.6, this would convert to 18,800 mAH, or about 94% efficiency based on advertised capacity. This is exceptionally good. I had another battery usb-c PD battery which could barely do 80% of rated capacity, and I've watched numerous reviews of solar generators, and have seen that anything over 90% is really quite exceptional. The build quality seems quite good, and it comes with a usb-c cable and a mesh bag. The percent LED meter on the front of the bank is quite good, and registers 1% increments. Its calibration isn't quite right, as it stopped on 1% for nearly an hour before full discharge. But that's a very minor quibble. It has an interesting slide-out bar on the top to the left of the LED screen. I'm not sure what its purpose is, but perhaps a place to rest a phone, or a way to grip/hold the battery with a single finger? It could work for either purpose. Also it does indeed charge at 45W (at least). I assume it can discharge at 65W, but I can't say for sure because my laptop never uses more than 45W, so that's the maximum rate I was able to test. Of course I've only had it for a day so I can't speak yet to its durability, but so far I'm very impressed by its performance! Review: The Best Portable Charger for Every Need! - I’ve tried many power banks before, but INIU has quickly become my go-to brand. Their 20,000 mAh, 65 W power bank is the most powerful, compact, and reliable charger I’ve ever owned. Charging Ability: With 65 W output, it enables me to charge almost all my devices at their maximum charging speed. For my Samsung S22 Ultra, it takes about an hour to charge back to full. I mainly start charging my phone again throughout the day when it's around 30% and to get up to around 80% again with this portable charger takes about 30 minutes and only takes away around 15 to 20% of the portable charger's full capacity. I also bought this charger to help charge my Rog Ally, but I haven't tested it yet. I estimate it could charge the Rog Ally to full again pretty quickly, but use up around 70% of its power. I can confidently say though I can get multiple phone charges no problem without worrying this will run out of battery with 20,000 mAh. Size: I love the size of this mini portable charger. Even with 20,000 mAh, it’s compact enough to meet airline carry-on requirements and fits neatly into my backpack or travel pouch without feeling like dead weight. It is around half the size of my first Inui charger that I've bought, which is the normal size. I feel like this one is small enough to also slip into your pocket, no issue. Design: The build feels premium and durable. I like the easy-to-use on-screen display, which works by pressing the power button once. A big thing I like about this one in particular is the cord that is tied to the side of the device. This cord makes it so convenient to charge my phone when I don't have any wires with me on hand. The cord on the side of the device is USB-C and supports up to 100 watts. If you need one reliable charger for a phone, laptop, or travel emergencies, INIU is where it’s at. I’ve used cheaper brands, but nothing comes close to this perfect balance of speed, capacity, and portability. It's absolutely the best power bank I’ve ever owned. ## 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 ### ⭐⭐⭐⭐⭐ powerhouse!

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. ## Frequently Bought Together - INIU Power Bank, 20000mAh 65W Ultra Compact USB C Laptop Portable Charger, PD QC Fast Charging 3-Output External Battery Pack for Laptop MacBook iPad Tablet Steam Deck iPhone 16 15 14 Pro Samsung S22 - INIU USB C to USB C Cable, 240W Fast Charging [6.6ft, 2-Pack] Type C Charger Cord, Braided USBC Phone Charger Cable for iPhone 16 15 Pro Samsung S24 S23 Laptops MacBook iPad Switch Steam Deck etc. - INIU Portable Charger, Ultra Small 10000mAh 45W PD Power Bank, USB C in&Out Fast Charging Battery Pack, Travel Essentials Powerbank for iPhone 16/15/14/13 Pro Max, iPad mini/Air, Samsung S22 S21 etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/648335642-iniu-laptop-power-bank-smallest-20000mah-65w-fast-charging-battery](https://www.desertcart.us/products/648335642-iniu-laptop-power-bank-smallest-20000mah-65w-fast-charging-battery) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-29*
