Recommended, good performance & lightweight
Very impressed. It is a little heavy but its lightweight compared to others with this capability. I’m quite happy to put this in my handbag but returned others as they were too heavy. Similarly this one lives up to its promise on charging capability. I’ve used it several times now & I get around 5 full charges for a new iPhone 14. It does take a few hours to charge back up but I don’t think this is a problem given its other attributes

Excellent product and amazing customer service.
⭐️⭐️⭐️⭐️⭐️ Perfect Power Bank! This INIU power bank is fantastic! It charges my phone incredibly fast, and the 20,000mAh capacity lasts for days. I love that the USB-C port works for both input and output—super convenient. Solid build, great value, and extremely reliable. Great for Travel Bought this for a long trip, and it didn’t disappoint. I charged my phone multiple times and still had power left. The fast charging works exactly as advertised. Not too heavy for the capacity and easy to carry around. Charges Everything Quickly Really impressed with the 22.5W fast charging. My iPhone and tablet both charge much faster than with my older power bank. The display is clear and the build quality feels premium. Definitely worth the price. Reliable and Powerful I keep this in my bag every day. It’s dependable, holds a ton of power, and recharges itself pretty quickly with USB-C. Perfect for work, travel, or emergencies. Would absolutely buy again. Excellent customer service, the team were very professional and helpful to resolve an issue quickly. Highly recommended

Perfect Power Bank for Quest 3 ❤️
Fabulous Power Bank. Worth every penny. Using it with a Quest 3. Keeps the headset charging without any 'low charge rate' type errors in the headset. Was checking the headset battery level during usage, and it keeps the Quest 3 at the same % throughout with no droppage. Nice digital battery % display. Using with 'UGREEN 60W USB-C Charger Cable' also from Amazon. Which has a Right Angled (L-shaped) fitting for connecting to the headset. Perfect combination and recommended 👍

Great for charging and long lasting power
Great to use if you have no way of charging your phone for afew days. Takes a while to charge up the product however the charge on this lasts for a long time. The power bank is a little bulky when trying to fit in a small bag. Had no experiences of overheating and has a mini torch which comes in handy when camping. Overall, I would buy again and great value for money

Amazing Power Bank !!!
Wow .... very impressed !!! , I bought this power bank to use with my heated gilet .... I needed one that would last all day outside , and I did a really long search into brands /reviews etc , changing my mind almost daily , then finally settling on this one !! It did not disappoint at all , it did take a while to charge , but that wasn't a problem ... when it arrived I did think that it might be a little heavy , but actually once it was in the gilet storage pocket , I didnt notice the weight at all , even when I was running , totally forgot it was there and it didnt make a difference at all ! I turned this on approx 6.50am , and it lasted me the whole day , it was switched off around 5pm when I got back in my van to go home , and it was still showing 33% battery 🙂 ..... It feels very well made and love the non slip casing its housed in , my other power banks do tend to slip through my fingers .... It comes with a fab little mesh carry bag and charging cable , and it was just plug and go .... very very impressed ... when funds allow I will look at buying another as theyre very handy things to have around , especially when I start camping again in April ... I bought this based on my own reviews and research and am not affiliated with the brand in any way .... but would def recommend them !!!

Good value 20000 mAh Power Bank
This is my 3rd (or 4th, I lose track) 20000mAh power bank from INIU. Not because I keep replacing them, but they are so good I keep adding them to my collection. I was very impressed with my first one, bought several years ago I added a few more. They are moderately hefty (fair chunk of cells in the bar of soap-shaped case for 20000 mAh) but actually quite a small footprint. It has a nice clear readout of % charge left (0-100% shows in 1% increments) and a handy (ish) white LED light / torch function, which surprisingly, I use fairly frequently (push button on the side which activates the torch with a double press or turns it off with another 2 presses. Port-wise, 2xUSB3 (standard A size, blue coloured insert) for output to a device, and a USB-C (in/out) which allows re-charging of the bank or charging of a device (not at the same time, obviously!). The selling point for me is you can long-press the power button to turn it off but more importantly it stays ON when charging very low current devices e.g. some earbuds or smart watches (or powering some low power USB devices such as LNAs for SDR applications). Many powerbanks turn off if only a tiny current is being drawn, these don't which is why I own 4. As a device charger, they are great, they offer more rapid charge for my (android) phones that require it (can't comment on the fruity phones or devices as I don't own or use them, but I would assume the same for them). For the more nerdy types, I use one to power a 5v Bias-Tee for a small active antenna, and a fully charged bank lasts in the region of 2 or more weeks (and eliminates USB noise from SDR Bias-Tee or USB ports on computers). Comes nice packaged in a box, with brief user guide and guarantee card, a nice mesh drawstring bag, a 30 cm USB-A to USB-C cable (I assume charge only, never used them as have a set of other cables to do that job). And that's your lot. I regularly buy them on offer which makes them even more value for money. Next time I see one reduced, I'll probably add another to the collection as I really do like them. Good stuff!

Do I recommend it , Short Answer Yes! I’m dept review I bought this because of the changing in times we are living in & the power going out here in Ireland, been in my mid 30’s it’s honestly unheard of the power going down But it happens more & more often unfortunately this is why I bought it & to update for ones I bought years ago with a well known safe brand I own over ten power banks, This build quality is in the top 3 it really is! You get a full 3 year warranty with it It’s super sleek , it’s Really well made , it’s small it’s not that heavy for the mAh it’s really not It has a really nice display that’s big & clear , mine came with 55% which is the norm You get a USB A to USB C cable it’s not long maybe 6/7 inches ( that’s my only con which is nitpicking as they often don’t come with one ) The packaging is really nice , it’s very straight forward, push on , 2 fast pushes for the LED Light & sane to turn off super easy. Been USB C , It can recharge a lot faster & it’s really quick to charge my IPhone 11 usb A to Lighten People might think it’s heavy , For the power 20,000mAh it’s really not! , it’s really sleek & has a soft feel like velvet is the best way I can explain it but it’s really sturdy! But you can tell it’s made to last & anything with 3 year’s warranty at this price with this much power & at the speed it charges your phone or itself It’s a steal , such a bargain! I 100% recommend this. Buy it! *EDIT - UPDATE* - I charged this to 90% ( btw is the norm don’t charge to 100% and put stress on the batteries just sitting there as it’s just sitting there ) So 7 weeks later I checked it today 5th of June 2025 , it’s still at 90% & I plugged it in my phone for 15 mins , didn’t get hot , works perfectly as expected with the build quality reviews & from tech sites it’s the cheap but amazing quality powerbank ( build quality is my number 1 and it meets it it’s no different than my Ankler or Ugreen ) now I know I can put this in the drawer knowing when the power goes Click! I’m good , is such a peace of mind , this is the very same quality as Ankler & Ugreen imo, power is power at the end of the day , yes INIU is a new company, but with millions sold in the states & all over Europe & no horror stories, it’s such a peace of mind , also it’s not heavy IMO , it’s not it weight is about 4 times your phone ( if that is heavy to you ) if you are going out for a day long train or an overnight event 10,000mAh is Loads , imo this is for an emergency , I can’t rate it higher for the cost , build quality , power holding , and the price in around €20 quid it’s such a steal , Said I’d update to help someone to decide! As build quality is the most important thing to me then the power & it does both whats it ment to , on the tin so to speak And who doesn’t like a bargain , it will definitely go up in price. Hope this helps someone out

Sono molto soddisfatto di questo power bank. La capacità di ricarica è ottima e la velocità di ricarica è davvero veloce. Il display che mostra la riserva di energia è molto utile e ti permette di tenere sempre tutto sotto controllo. Le dimensioni sono abbastanza compatte e il rapporto qualità-prezzo è sicuramente favorevole. L'unico aspetto che potrebbe essere migliorato è il peso: per alcuni potrebbe risultare un po' pesante e ingombrante, ma nel complesso è un prodotto che consiglio per chi cerca un power bank affidabile.
