INIU Power Bank, 25000mAh 100W High Capacity Laptop & Phone Portable Charger, Fast Charging Flight Cruise Ship Family Essentials Traveling Powerbank for College Student Traveler Teen Boys Girls, White

Beautiful colour and design. The display is sufficient, its weight is normal for a 25000mAh unit. It charges 2 Ipads , or more than 2 iphones when fully charged. Its capacity matched my expectations . It also charges the Macbook pro without any issues. Charging speed is sufficient, there are faster chargers in the market but this charger is well optimized. Good for frequent travellers, the yellow colour makes it highly visible and easier to find. Case size is suitable for coat pocket, but it might not fit any trouser pocket. Charging cable looks sturdy and durable. No issues so far.

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.

Decent power bank but quite chunky i knew it would be bigger from the pictures but it’s quite heavy aswell feels like your carrying a brick in your pocket. That being said if you keep it in a backpack I’d say it’s a really good power bank battery life is good charging speed is good has both usb A and C ports so good functionality. INIU make the best power banks I got another smaller one from them which I carry in my pocket and it charges my phone twice which is more the enough for my work day as a delivery driver.

A solidly built, fast-changing piece of kit that I carry when travelling. It charges my Samsung Z Fold faster than my Samsung mains charger and powers my laptop. Chunky and a little heavy but I'm fine with this given it's excellent performance. And it can be taken onboard flights (the wattage is shown on the back to show airport security it's 100w if the need arises).

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).

INIU are great for chargers & this one is super too. Battery life is very good, easy to use. Great quality. Feels good to hold. Charges well.

Arrived with 1% battery, which has likely been the case for many weeks or months, resulting in irreversible capacity loss, increasing the risk of failure and accelerated aging of the lithium cells. After charging for 1 hour using a PD3.0 charger, likely at 65w due to comparative charging of other devices), it has reached 2% so I fear the battery has indeed suffered irreversible damage due to being stored at such a low charge. Lithium batteries should never ever be stored empty like this! I previously purchased the P51L-E2 and it has been flawless for months, but this -100w 25,000mAh model BI-B63 - I cannot recommend.

Great power bank very powerful and works great
