INIU 100W 25000mAh Portable Charger for Laptop & Phone, Power Bank with PD QC Fast Charging (USB-C in/Out) - High Capacity Electronics Battery Pack for iPad, Samsung, Travel, Camping, Hiking

Superb product.

I absolutely love this power bank, I’ve tried loads and this is by far the best. It’s chunky and a bit heavy, which isn’t in any way a criticism, it’s just a physical limitation as these things can only be so light and still work.A physical limitation INIU do seem to have overcome though is the overall size. For a power bank of this capacity, this is absolutely tiny.Build quality and charging speed are both very good. I use a Ugreen 65w plug to charge it with and it charges from 0-100% in just over two hours. If you used a 100w plug, you’d be even quicker.This may be a little niche, but I use this to power a lens warmer while I’m doing astrophotography. With my lens warmer on medium, this will last about 8 hours (tested at -6°c) which is more than enough! It will also stay on the whole time. Some power banks will auto power off with lens warmers due to the way they intermittently pull power to keep a constant temp. This one doesn’t, which is great.Price is fair, no complaints in that department.It’s pretty much plug and play out of the box, so very easy to use.

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.

Seems to do the job charges fast but for some weird reason 99 to 100% charge takes like 30 mins I don't know if it's a fault I hopeNot but the charging performance is phenomenal I can power my rog ally for upto 3 hours and it allows 30w turbo and charge my phone at the same time wow 👌

The best power bank I’ve owned. Charges quickly and transfers power to my devices quickly. A good solid construction.

Excellent power banks, I have three. Really pleased.

Great little power bank for my Steam Deck when I'm out and around or have a little bit of time to play when I'm on my break at work. Very versatile with different ports and can charge any device a few times.

The power bank is really good, but I'm sceptical about using it after the Amazon delivery staff dropped it over the fence at a height of over 2 meters. The user manual clearly mentions not dropping the power bank. I will return it and repurchase a new one, as there's no straightforward return and exchange procedure.
