Description

What’s the Difference Between 65W, 100W, and 140W Laptop Power Banks? 65W: Great for lightweight laptops like MacBook Air；100W: Covers most high-performance laptops.；140W: Needed for ultra-high-performance laptops and full-speed PD 3.1 charging. Choose a power bank based on your laptop’s max input and daily workload. Can a Laptop Power Bank Damage My Laptop Battery? 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. Why Does My Power Bank Provide Fewer Charges Than Expected? 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. How to Calculate the Possible Number of Charges? Formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges. Example: (20000mAh × 0.65) ÷ 3692mAh ≈ 3.5 charges for iPhone 17. Does It Support Pass-Through Charging? Yes. The power bank supports pass-through charging, allowing you to charge the power bank and connected devices at the same time.

Irma Gerd, baw-dang! This is great power bank!
I love INIU power banks. I have a lot of their 20k banks which we constantly use just about everywhere. Travel, at a game, in a purse or backpack, camping, you name it, everyone has their power bank. The 20k will charge a Samsung S20 about 6 times. I don't care what it does for ijunk, but if you are a victim of those products, this bank will charge those too, with the right cord. I wanted a bigger power bank to keep in my laptop bag so I went with another bank from INIU. This time a 25k model. I am still SUUUUPER happy with their products. This bank has both USB-C and USB-A ports so you can get power out of it easily, but it depends on your cords. It is super easy to use, even with the mesh bag. At first I thought the bag was bit gimmicky, but I actually love it. There is just enough room in the bag to jam a phone and the bank inside so they stay tethered together. I don't use it that way, but its good to know what it can do. I keep the cord that came in the box with the bank at all times. That way I NEVER haver to worry about finding the right cord. All my devices are USB-C anyway, but still, the cord is a USB-C to USB-A so I can charge a friend's device in a pinch. The battery life on this bank is great. Like I said, the 20k will charge a Samsung S20 about 6 times. This one will do it 10. That count depends on the charge on the phone already, but I can travel in the wilderness for two weeks and keep my phone charged the whole time and still have a bit left at the end. It does take a while to charge. That would be my only complaint. From 0% to 100% probably takes about 6-8 hours. Not a problem at all for me. That Samsung S20 accepts fast charging and this bank can deliver. Just be sure you are using the right port. I am running a Surface Laptop 4 whose native charger is rated for 65W. I was hoping that this battery bank would be able to keep me charged while working remotely for at least one day. It does, but it can depend on what I am doing. If I taxing the laptop to the point where its cooling fans kick on, the drain on the battery bank is a lot. I still get about a day's power out of the bank, so that is awesome. I have found that the best way to use the power bank is to let the laptop battery get down to under 20%, then put the bank on. The bank will charge the laptop just like it is plugged into the wall and will recharge to 100% in about an hour. Then I put the bank back in the bag and repeat as needed. It seems that I get more out of the bank when I do this, or it might just be the BMS of the two devices working smarter. This bank has some heft. But that is to be expected for this much power. The weight is not a problem as this bank is always part of a tech bag, but if you think you could carry it around in your pocket, yeah, don't. I put this bank in my bag when we explored New Orleans this year. I had 3 cables for it and it was able to charge up 5 very hungry phones and still had 30% charge after 14 hours. INUI banks are very well made and I have yet to have one fail. Our house has 11 INIU banks. Most of them ar the 20k, but we have a 10k and now two of these 25k. All of them are excellent. ... show more

7th month review!
Hey guys so I’d like to start by saying I absolutely adore this powerbank I love batteries and solar stuff in general and I just love the way this powerbank feels in the hand the capacity is pretty true enough to specs it’ll charge my iPhone 11 Pro Max from 0 to 100% using 100% down to 84% of its starting power. Of course you do tend to get the less drain when the bank is high percent. So maybe it would take say 20% of its numerical value from 40% and under to charge same said phone. However this has been a near daily partner for me love love love it. I used the 20k version I’d say a good 6 months or longer before they invented this 25k unit. Love them both and I would say the 20k has juuuuust about the same capacity almost identical in real world use just about down to the percent guys. Except this bad boy can output 65 watts for the big boy devices. And what’s better is is can solar charge off a small foldable 60 watt panel at 45 watts in 65 out. So this guy charges pretty quick in about 2 hours. But mines always less cause I take care of my batteries and I very rarely ever let my lithium batterys drop below say 30s percent. And I don’t think this boy has ever been close 0% and only 100% maybe 6-10 times max I always try to keep it around 50-80% I think it has held its capacity great absolutely great I can’t notice a real world difference in percent loss when charging since day one and i use (2) phones at work daily. Love the powerbank live the carring case it comes with it’s just a nice soft sell formed rubber coating and just feels quality and solid weight in the hand no rattles just a solid brick in stylish formate with a great (percentage based display) I love being able to offer my family charges while on trips to church ect and brag about the banks performance and stellar recharge (itself) time. It charges 3 times faster then it’s 20k little brother and can triple the power out for devices. I’d say their is a bit of a let down as this power bank isnit pps compatible charger. And that’s basically needed to fast charge say my Samsung ultra 2023 at 2.0 max speed. Samsung requires a charger to be pps. I guess it’s basically like a chip that slows the charger to talk to Samsung phones or maybe other devices and androids. However that’s to achieve fast charge 2.0 display to pop up on the s23 ultra to say hey I’m getting like a lot of watts (up to 40). However this power bank gets the job done just fine and plenty quickly enough as the s23 ultra don’t really ever use 45 watts unless it’s really really low and even that’s temporary. So you hardly notice much a difference in using this power bank opposed to a 45 watt (pps) wall charger. You may get from say 30% to 85% 5 or 7 minutes faster so but the time you really notice it’s already been those extra handful of minutes and it’s sitting at 85% so still plenty fast enough so won’t doc it to hard there. However I will say I take such good care of this bank it’s my daily companion and I was pretty dissapointed today that the 65 watt port the (charging the bank port) no longer functions. I trued different cables and then eventually tried to detail clean it being gentle however it simple has given out. Now let’s see how iniu as a company responds and will get back to you guys for an update! By the way the other ports are working flawless and the capacity is still spot on. I do however wish at least one other port could take over the responsibility of recharging the unit itself as guys your relying on one port significantly to keep this powerbank lasting for years and unfortunately even with good care this all important 65 watt port decided it would it call it a day for good. However I will update you guys and see if iniu will step up and stand behind thier power banks! That’s for the read sorry about the length :))) I’ll update my rating after we see how it’s handled thanks guys! UPDATE *** 11/13/23 I’m very happy to say both Amazon and Iniu both had great reps and they had sent me a new unit out with all the bells and whistles. A new carry bag and two new cables just like buying it brand new. I would like to change my review to 5 stars simple because I truly do love this unit. Iniu is one of the good ones who do actually put the amount of mAH in their battery banks. You’ll get plenty of goo steady power from this champion and I put it to the test for over the 7 months. Everywhere I went it went suppling power two 2 phones (one on hotspot). You’ll love the feel of this case and the easy read (%) display. Battery bar displays are a no go for me I really like to know the exact amount of power that I’m using and what I have left. It also allows me to monitor the capacity as when I first charged my iPhone 11 Pro Max for 0% to 100% the battery bank went from 100% to 84%. That’s good to know as time goes by to see if you end up around the same. And I’m happy to say this champ was about in the exact same percent over daily use for 7 months. I also was using a 45 watt charger a decent portion of the time so the 65 watt port was well used and ports do unfortunately fail from time to time. But it’s a good test for iniu to see how how they approach their warranty. And I’m happy to say they backed it up 100%. Their warranty says they’ll replace your unit with a refurbished if they have then stock if not you’ll get s brand new unit. This one has what looks to be (possibly) the smallest little pinprick on one side where maybe they had repaired it… but it could be just a little speck of of torn rubber sticking up. However this unit is more prestine then my first that had scratches on the lcd screen. This one’s flawless besides the little thing in mentioned. Overall I can say I’m very satisfied with both Amazon rep I talked to and iniu who made sure I was taken well care of without sending anything back or to much hoops to jump through they got me set back up with go to companion once again and I’m very thankful to Amazon but Expecially iniu they passed the test guys so you won’t have to worry if your bank kills over from a port or something months down the road even 2 or 3 year I presume so out it to use and enjoy the convenience the comfort and feel of this premium power bank and know if anything goes wrong with it your covered. I’ll update again if anything happens with this one. In the meantime i may consider using about a 30 watt charger to charge the unit. Just because it can charge at 45 watts doesnit relaky mean you Must charge at max speed everytime. But the battery stew didnit mind it and no other port failed so it could be absolutely fine. It’s just eh if im not rushing to charge I may opt to enjoy still good speeds around 30 or so maybe 36 watts that would give my belkin charger a chance to be used and also may just be a little easier on the all to over used and important 65 watt port. The only post that recharges the unit itself… so guys as I said in the video shew I really do love solar and batterys and geeky powebanks and this one just Feeels so good in the hand you it let’s you know to take care of it you’ll enjoy this one and this company. But just to be sure I’ll update if anything happens :) if not we’ll I’ll be out there somewhere using this powerbank daily once again thanks to iniu :) ... show more

Save Your Hairline!
Stressing out about a dead laptop or dead phone has ruined my day more than I care to admit. For college students, travelers, or anybody who wants the most from a power bank, this will definitely help prevent stress induced hair loss. I’ve had my phone die while stranded away from home, and I’ve had my laptop die mid-class. I chose to say bye to those cruel moments. I chose INIU because it’s definitely the best price to capacity/output while still being trustworthy. I got the classic size 25000 mAh model at 100W and this thing is perfect for my uses. For $10 more you can get a more compact model but this was still lighter than my Lenovo Laptop 170W slim charger while charging other things too. Since the classic size was on sale I went for the cheaper option. Great for gaming laptops if that’s your need. I get a few more hours out of mine, definitely makes the difference and eases the blow from not choosing a laptop that can't game. Which, this is definitely more for users of laptops or any other power hungry devices. Most other things won’t support 100W charging so your money is better spent on cheaper models. 20k mAh at 65W is probably the highest I’d go if I didn’t have a laptop. The 100W output is the main attraction here, my gaming laptop dies quickly but has a USB-C lightning port. This gives it the perfect power delivery in between it’s 60W minimum and 140W maximum, if you want the fastest charging then obviously buy the 27k mAh at 140W output. Yes the usb-c to usb-c cable they include supports 100W charging! No need to buy another unless you want a longer or more quality cable. The power bank itself charges admirably fast. I only have a 30W charger in hand for now but even at half of its 65W charging maximum, it’s pretty quick. I usually give myself an hour in the morning to get ready and leave, even if this was at 0% it’ll charge fast enough to get me through the day. Durability wise this thing is solid. I don’t LOVE the soft touch plastic used, it picks up finger prints and any oil on your hands like nobodies business, but it definitely feels more solid than your run of the mill hard plastic. The thing you want to avoid in a power bank are any cracks or punctures. A hard fall at a bad angle would crack cheaper plastic but not this tough shell. Metal gets hot and doesn’t absorb as much of the impact. So this was definitely the best choice. Maybe it could have a different finish but I usually charge it out of it's little pouch regardless. The only reason to take it out would be for the phone holder. All in all this is an invaluable purchase. The second I opened this and plugged it into my computer I felt my stress wash away. In 2025 a good power bank is almost necessary. Unless you upgrade phones every other year it’s probably not lasting an entire day of use. I also don’t have to look around the room for outlets to charge my laptop at during class. Great purchase ... show more

This takes a long time to charge the battery, but once it is charged it will fast charge your devices. I love that the handle is a cord which I didn't know until my husband told me. This is the approved wattage for travel on planes and it is a smaller size which is good.

A travel essential -- got us through transatlantic flights without breaking a sweat
We took these INIU power banks on our transatlantic flights and they were exactly what we needed. Plenty of capacity to keep multiple devices charged throughout long travel days, charges devices fast, and recharges itself quickly too which is a bonus when you have limited time at an outlet. It also meets current airline requirements, which was a relief -- our previous power bank was larger and I was genuinely worried about it getting confiscated going through European airports. One quirk worth mentioning: I had trouble getting the battery indicator to read 100%. It would get close but never quite show a full charge. Didn't affect performance at all, just a minor annoyance with the display. Pros: - Massive capacity -- handled multiple devices across long travel days - Fast charging output - Recharges itself quickly - Meets current airline carry-on requirements - Reliable and compact enough for travel Cons: - Battery indicator wouldn't consistently show 100% even when fully charged A must-have for long trips. Won't travel without it. ... show more

One Year Review
One-Year Review Still Worth Every Penny Just wanted to give a quick review after using this thing for almost a year. I picked it up back in August, and honestly, it’s been amazing. For the price, it’s worth every penny and then some. Performance:
 At the start, I was getting about 7–8 full charges on phones like the iPhone XR, iPhone 12, and iPhone 12 Pro. And keep in mind, I use my phone a lot such as FaceTime, YouTube, movies, all that stuff that eats battery. I always used the fast-charging port too, and it did a great job getting things charged up quick. Depending on if I was using the phone while it charged or not, it usually took around 20–35 minutes if I was using it, or 15–25 minutes if I left it alone on Low Power Mode. Either way, pretty fast. Cons:
 Now, a few things to keep in mind. One small annoyance is that you have to turn the device on first before plugging your phone in. It won’t start charging if you do it the other way around. Would’ve been nice if it just kicked in automatically. Another thing is the port wear over time. It has two USB-C ports and a USB-A, so plenty of options, but after almost a year of regular use, the connection isn’t as solid as it used to be. I’ve never dropped it or yanked on the cables or anything, so I think it’s just normal wear from always having to plug and unplug to start a charge. Over time, the charge doesn’t last as long and the battery drains faster than it used to. After nearly a year of heavy use, I’m probably due for a new one soon but again, for the price, I can’t complain. Sometimes, after charging a device or mid-charge, it randomly shuts off even when there’s still plenty of battery left. Not super common, but it’s happened enough to notice. Also, it really only handles charging one thing at a time. If you plug in two devices, one just stops charging. Pros:
 Now for the good stuff, which is most of it. It charges your phone fast. Like, way faster than some wall chargers I’ve used. And if you use a solid fast-charging cable with it (which I recommend), it really shows. The difference is noticeable. Yeah, it’s a little bulky but that’s to be expected. It fits fine in a hoodie or jacket pocket. The design is smooth, and the rounded corners are nice and won’t poke you or anything. One of my favorite features is the built-in stand at the bottom. You can pull it out and rest your phone on it while it’s charging, which is super handy if you’re watching something or listening to music. I’ve even used it on a flight and it was perfect. And yes, you can bring it on planes with no issue. Even when the power bank heats up during charging, you don’t feel any of that heat on your phone, which is a nice touch. Charging the power bank itself takes a few hours, so I usually just leave it overnight. But honestly, with how many times it charges your devices, it’s not a big deal at all. The battery on this thing lasts a long time. Like, so long that I started carrying it with me everywhere just in case. You get hooked on having that much backup power. Final Thoughts:
All in all, even if you only get a year of solid use out of it, it’s absolutely worth it. For the price, it’s a no-brainer. If you ever see it on sale grab it. You won’t regret it. ... show more
