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

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!

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.

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.

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.

Bought the power bank as it was on price cut and I need one to replace a faulty one. I was surprised to find a thick power bank when I opened the package. It was at least 0.25 to 0.5 inch thicker than those pictures in the product description and it was quite heavy too (see picture). Anyway, I bought it to power my laptop computer and it does its job. When I recharged it after a couple of cycles of use, it went dead as you can see in the video. The screen kept on blinking and it couldn't charge. I googled the issue and found restarting the power is one of the solutions. And so I did. It's working fine now but I don't know if the same problem would happen again. The product comes with a slider and it was a mobile phone stand indeed. It's a thoughtful design (see pictures). It also comes with a short USB c cable and cheap cloth bag for storage. Overall, I'm not impressed with the pictures at the description of the product not matching the exact product, which gives people a wrong impression of the thickness of the power bank. I'm also worried about the reliability of the product. Therefore I took one star off each. Other than that, the power bank works fine after two months of use. I think there are other similar products in the market for consideration and I will go for other brands should I need one in the future. [Added after customer service contacted] After I posted the above review, the after-sales customer service of Amazon send a letter to me and offered me a brand new replacement of the power bank with 3 years warranty. I'm impressed with the gesture and so I took the offer as the previous one has issue there. I might need one as backup in case the previous one fails again. I'm impressed with the customer service but not the product and I have to be true to myself. Still, the picture the customer service used in the letter is not a genuine reflection of the actual thickness of the product, which lured me into purchasing the product (it is at least 1/4 inch thicker than the picture). Overall, I am very impressed with the quality of the after-sales service but not so much for the product. I do not want to mislead others in this review for the power bank and I'm sorry that I have to maintain the same review rating for the product. Revised October 2024 After a year's of usage, I have decided to revise my previous review and give it a 4 stars rating for its power and endurance. It still works as well as it was a year ago and the reliability issue seems to be gone as time goes by. It can charge my phones multiple times before I have to recharge the power bank. It's not a power bank that you can carry around in your clothes pocket but considering the high output it provides and the power bank is a product made a year ago, it's good for what it supposed to do.

Hmmm…. Not a good product at all. Said it was 100% charged when plugging in a charger. Then it says 1% with a load attached but won’t actually power the unit. Plug it into a charger and it counts up 100% suspiciously quickly but once again, attach a load and it says 1% Tried with cable supplied as well as Apple ones. Tried 4 chargers and iPhone 16

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.

Very good, lasts quite a long time between changing

Excellent product. Highly recommended.

Piccola ma potente, ricarica velocemente lo smartphone, e si ricarica essa stessa molto velocemente: un ottimo prodotto e un ottimo acquisto: la consiglio a tutti!!

Il power bank porta il marchio INIU ed arriva insieme ad una cavetto doppio USB-C maschio, una custodia a rete e libretto istruzioni multilingue di cui anche l'Italiano. Le sue dimensioni sono 10,8 x 6,8 x 3,5cm e pesa 393 grammi, ben al di sotto degli standards finora imposti da una capacità simile (25000mAh)! A pensarci bene questo power bank agli ioni di litio rappresenta davvero un must per gli utenti che usano più dispositivi energivori, dal momento che riesce ad offrire una carica ad alta velocità di 110W max per 2 dispositivi contemporaneamente, vantando tecnologie all'avanguardia come la TinyCell e la HyperStack! Le velocità con cui riesce a caricare completamente dispositivi con capacità di batteria importanti (iPhone, MacBook, Samsung, ecc...) sono impressionanti e vanno dai soli 25 minuti ai 94 minuti! Ovviamente va da se che il dispositivo collegato a questo tipo di power bank ultra veloce deve a sua volta supportare anch'esso velocità di carica simili, altrimenti il dispositivo avrà, grazie alla presenza di chips intelligenti, la carica max che riesce a supportare. Il power bank è munito di display luminoso in grado di indicarci in qualsiasi momento il suo stato di carica, di un pulsante Power e di ben tre interfacce di cui 2 (USB-C e USB-C2) funzionanti in modalità OUT (uscita) ed una OUT/IN (quella USB-C1). Quest'ultima è in grado di erogare una carica da 100W max mentre le altre due raggiungono potenze da 45W (USB-C2) e 18W (USB-A) rispettivamente. La corrente in entrata può essere di 65W max (5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A) mentre quella in uscita della USB-C2 raggiungere i 45W max (5V/9V/12V/15V - 3A), contro i 18W max di quella in uscita della USB-C2 (5V/9V - 3A & 12V-1.5A). I protocolli di carica veloce rispettati sono: PD3.0, PD2.0, QC3.0, QC2.0, PPS, AFC, ecc... Punti a favore: - capacità 25000mAh - potenza max erogabile 100W - alta velocità di carica - peso ed ingombri ridotti - 3 interfacce in uscita (di cui una in entrata) - ampia compatibilità - display luminoso indicatore di carica - protezioni contro sovraccarico, cortocircuito, sovratensione, ecc... - custodia a rete - manuale d'uso anche in Italiano. Punti contro: al momento nessuno. Considerazioni finali: Innovazioni del genere che riescono a mettere in discussione le leggi della fisica, rischiando di superarle ed alzando sempre di più l'asticella delle prestazioni non possono che suscitarmi interesse ragion per cui ne feci richiesta. Prendendo in mano questa batteria esterna della INIU ho avuto modo di paragonarla con un'altra di pari capienza circa (22000mAh) ma molto meno veloce, che comunque pesava ed ingombrava di più. Come si vede nel video l'ho collegata ad un dispositivo che supporta la carica veloce anche se non di quel livello per cui il circuito intelligente integrato ha provveduto ad abbassarne la potenza di erogazione adeguandola alle necessità del dispositivo. Essendo provvisto di un adattatore in grado di fornire informazioni di carica (Potenza, Amperaggio e Voltaggio) sono riuscito a vedere fino a quanto è riuscito a spingersi durante il procedimento di carica. Per riuscire a caricare in breve tempo una batteria esterna come questa, con capacità da 25000mAh, bisogna avere a disposizione alimentatori da 65W altrimenti ci vorrà molto tempo (10 e più ore) per portarla a piena carica. Mi è arrivata con una carica di 50% e si sono volute più di 5 ore per raggiungere il 100% di carica. Da appassionato di attività all'aperto mi serviva una power bank molto capiente in grado di offrirmi l'energia necessaria per tenere operativi 2-3 dispositivi contemporaneamente per più giorni. Questo mi permetterebbe anche di ridurre pesi ed ingombri lasciando a casa il mio pannello solare da 25W. Durante la mia prova l'ho voluta collegare a due smartphones contemporaneamente per provare le sue capacità. I miei dispositivi si stavano ricaricando velocemente e senza surriscaldarsi riuscendo a raggiungere la piena carica in molto meno tempo rispetto a quello che richiedono abitualmente quando vengono attaccati ad altri power banks. In conclusione posso ritenermi soddisfatto delle sue prestazioni in particolare con la rapidità con cui completa la carica del dispositivo ad essa collegato. Posso di conseguenza consigliarne l'acquisto aggiungendo che pur essendo di capacità simile (25000mAh) trova facilmente posto in qualsiasi tasca e/o borsetta. Rapporto qualità/prezzo adeguato!

Molto soddisfatto sia della power-bank sia del servizio di assistenza post-vendita; dopo aver segnalato un problema hanno risposto in tempi rapidi e risolto.

Perfetta fa tutto quello che dice nella descrizione
