Laptop Power Bank, Smallest 25000mAh 100W Fast Charging Battery Pack

There is nothing light about this power bank (about 500g) which is what you would expect with a big battery (multiple batteries inside). If it was light then it wouldn't be able to deliver the power. I use my phone as a mobile hotspot for my tablet when I work outside and needed something to charge both on days when I use the devices heavily. It managed to fast charge my phone and charge my tablet simultaneously. My old power bank simply couldn't fast charge anything and couldn't deliver enough power to charge the tablet at all and therefore I couldn't work all day without finding an AC adapter. This one looks and feels quality. Many other power banks (cheaper) either lie about their capacity or simply disappoint - this one does exactly what it says it will. Very pleased that I invested in it. Best power bank I have had. Lower power devices (ear buds etc) will need to be charged from the 18w port I found, therefore you may need to carry 2 cables (USB-A and USB-A). The bank comes with a short USB-C cable so you may need a USB-A to USB-C cable for some devices. Make sure that you use good cables to fast charge devices not cheap cables. [UPDATE] I have bought a USB-C to 5.5x2.5mm barrell adapter so that I can run my Gigabyte G5 gaming laptop. I also bought a USB-C cable that shows the charge in watts and can graph my laptop battery being charged and discharged. The laptop thinks the power bank is an ac adapter and therefore can charge the laptop battery at a rate of about 14 watts and run the laptop doing normal work (web browser and watching Amazon Prime video). The power needed to do this varies between 33 watts and 59 watts depending on what the laptop is doing. Power bank works great. I then got the GPU running and played Halo - the power bank delivered 110 watts (and even 114 watts momentaraly). The laptop wanted more power than this and so behaved as though the power plug was being plugged in and out every 5 to 20 seconds, when this happened the laptop is switching between its own battery and the power bank. The power bank therefore is working perfectly! If I stop using the GPU to play the game power usage returns back to 35 watts approx. During my tests the power bank ran the laptop for approx 45 minutes, charged the laptop from 25% to 40% and powered the laptop while in use and by the time I wrote this line the power bank was only down to 65%. The powerbank can deliver 110 watts momentarily and will sustain 100watts (I haven't found a way to demand 100 watts continually yet). It does deliver what it says it can. The photo shows the laptop playing a video and graphing the laptop battery charge and discharge while I tested. Just to show that I did test it. The blue part of the graph shows me trying to disharge the battery the red line shows when the power bank was running the laptop and charging the laptop. It shows at that moment the power bank was delivering 51 watts to the laptop and for my tests which lasted about 45 minutes the power bank only discharged down to 73%. While the GPU was demanding a lot of power it also shows that the laptop wasn't being charged and as soon as I stopped playing Halo charging resumed at 14 watts. Bottom line is this is a great power bank and works as advertised. Well pleased.

This has to be the best buying decision I've made. This is a beast! Very useful, very reliable. You can carry it on an airplane as well. Massive battery storage, can charge your phone, laptop, and other devices. It has fast charing, 40% to 95% within 30 minutes! This is a must have if you are traveling. It takes a lot of time to charge the power bank. Value for money! You will not regret buying this Although it does come with a cable, I would suggest buying a few cables from the brand as well along with it.

Great charger. Used in holiday in Spain and was able to keep my iPhone fully charged, which was important as I had boarding passes and accommodation access codes stored in my phone. It’s a little heavy but a great charger. The hanging strap is actually a built in charging and charger lead.

Really good. 3x almost full charges on my Xiaomi phone (5000mah battery) and it's at 57 percent. Worked perfectly on my weekend away camping. Fast charging too. Seams very well made. With a nice bag/case and charging cable seams of good quality by too. Very happy.

Very compact for its capacity, & fast charges all your appliances. Useful screen to check how much remains in it. Docked a star as it doesn't come with a pouch, & depletes quicker than I'd hoped - overall though, impressed enough to make this my go-to charger (out of several).

I bought the blue "mini-size" version. It's a pretty good size and weight for the power it can supply. The picture with the hand holding it is deceptive - perhaps photo-shopped? - or they have quite a large hand! I have average size male hands and I can't hold it like that! The size is actually around 11cm by 4.5cm by 7cm and it weighs in at 400g. I've used the power bank to charge an iPad with great results and I've also used it to power an Elektron Tonverk, again with excellent results. To power the Tonverk, I used a USB C to USB C cable from the in/out 1 port. It charges very well. I use my USB C MacBook Pro charger to charge it. I was initially disappointed to see there was no USB C charging cable included. But then realised that the cable is very cleverly the carrying strap! - A really nice bit of design. The 'strap' USB C to USB C cable is 16.5cm tip to tip and reassuringly robust. The display is simple and just displays the charge percent remaining - nothing else. This can be displayed with a press of the side button and then long-press to stop displaying. It holds charge well, with no loss at all when not in use. I've had this a month and a half now and there have been no issues at all. It's pretty good value for such a powerful power bank at the £57 I paid. I'm happy!

The claim about charging a laptop 1.5 times is really a lab claim and unclear how this was the case. Mine doesn't charge a laptop up to 30%. I wrote to Customer service of INIU, and the email reply was asking me to go through so many things to establish if the product is faulty or not that I felt it is a waste of time to do this to get a replacement. I just decided to return it to Amazon. For me, it is just another power bank with an unproven claim about a full laptop charge. Update 03/04/2026: Have been using this powerbank for some time now. What I like is that it can recharge quickly if you recharge it using a laptop charger with a usb-c charger. What I don't like is it's bulky and charging a laptop isn't so great.

It's funny that INIU seem to think these smarties of the Power Bank World are really for teenagers and young people! I am not a little bit older than that and I ADORE them. These are amazing Power Banks; beautifully made and designed in lots of smartie like colours - and wow! are they miniature. I have the 45W version and the 100W. The 100W is still small - but it is big! I mean.... it is not tiny! It is heavy too. BUT it packs a punch. Having tested the 45W mini versions (I have not tried the 65W versions - more on that later) - I would choose lots of the 45W versions rather than this beast.... but if you want the big power for a lap top this is probably your best bet. So before I do a quick comparison with Anker Power Banks - a quick word on availability. These are like gold dust. Nearly every colour is no longer available; most are now available in black. Until this week I had not heard of the brand at all. So now a comparison with Anker. These are much prettier things - Anker has nothing that comes close. These are also functional - not so many readouts and the cable is simpler. Instead of being welded, it is attached to the strap. Warranty: well Iniu promise three years no questions asked. I have not tested it. This is pretty much the best in the market. The big problem currently (May/June 2025) is complete lack of availability for almost all power Banks. I just wish they could keep up with demand - nearly everything is sold out. And please get more of the red, green and yellow ones! These are very little technological marvels - and we love them. You do not say that very often about Power Banks - but there you are. 5 STARS VERY highly recommended.
