INIU Power Bank, 20000mAh 22.5W PD3.0 QC4.0 Fast Charging Portable Charger

I have bought seven of these over the last six years and they are still going strong and work flawlessly. All still hold their charge and take between 6-8 hours to fully charge. They give off very little heat when charging or being charged. They've been used indoors for running single board computers, model vehicles and charging a variety of devices as well as outdoors for camping and hiking etc.

I purchased this before Christmas but have only just needed to use it as an emergency power pack. It is very impressive as it held all of its initial charge from months ago and very quickly charged up my iPad. It usefully has two standard USB ports and a USB C port. It’s a great bit of kit. Comes with a bag which easily holds a couple of different, short charging leads. Good value for money and widely compatible with various devices.

⭐️⭐️⭐️⭐️⭐️ 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

Excellent piece of kit. Well made, feels really substantial and clearly has a BIG battery in it. It works really well and charges up quite quickly for its size. Overall, I am REALLY happy with this Powerbank after buying some disappointing ones over the years. I only gave it 4* because I'm sick of manufacturers quoting their internal battery size, not the delivered performance. Unfortunately, like all manufacturers I suspect they are quoting the LiPo cell capacity - 20,000mWh at 3.7v rather than what you hope they are quoting which is how many mWh of USB output it will provide. I am sure that this is exactly the same capacity as many '20,000mWh' Powerbanks - and a lot better than the one I've just sent back from another manufacturer. For the 'anoraks' among us: The 'true' capacity is around 13,000 mWh of USB output, after 16,700mWh of USB input. So if you have a 2500mWh battery in your phone you should be able to charge it about 4 times from this. It DOES take a while to charge up - since 16,000mWh is pretty big. It started charging up at 1.88A from a high power USB charger, dropping to 0.48A after it was about half full, then dropping down to 0.19A for the last handful of %. Overall it took about 12 hours go go from completely flat to completely charged. I discharged it by powering a tablet at about 0.9A and it took over 12 hours to run down..... as you'd expect, with a USB monitor on it, which showed 12978mAh delivered (plus a bit for the meter itself). From tests I've done over the years - this is one of the best

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 !!!

Great power bank, reliable and robust. PLEASE remembner not to use where ambient temperature is much above 25c. Performance will be poorer and risk of accident higher for all and any lithium pwered solutions

Review: I absolutely love this power bank. It exceeded my expectations and is definitely money well spent. I'm a very active cyclist doing Uber Eats and Just Eat deliveries, so I needed something reliable. I tested it by keeping my phone connected almost all day during my deliveries, and the power bank still had over 60% battery left. It's compact enough to fit in a pocket, feels well made, and the digital display makes it easy to check the battery level. It also has a small built-in flashlight and can charge up to three devices at the same time. Another big plus was the delivery. It arrived very quickly here in the UK, which was a nice bonus. I highly recommend it. Excellent value for the price!

Great power bank, on full charge I can maybe get 5-7 full charges of my phone before it runs out

I've had this for almost a year and it is hands down the best powerbank I've ever had the pleasure of owning. It gets charged and emptied daily and it's still as good as it was in beginning. Can't recommend this enough!

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

Après des mois d'utilisation, je peux dire que c'est la meilleure batterie externe que je n'ai jamais vu. J'en ai aussi acheté pour offrir. Elle est extrêmement pratique et une fois rechargée, elle permet plusieurs rechargements pour vos appareils. C'est super qu'elle ait plusieurs ports de recharges et qu'elle indiqué facilement le pourcentage de batterie

Die powerbank ist super, ist auch gut am LED tisch unten mit magnet befestigt. Hält bombe...👍😀
