I bought this battery bank to use with a quest 3. Most battery banks cannot keep a quest 3 charged while playing because of the 18+ watts of power draw the quest 3 uses. This battery bank can deliver 22.5w from any one of its 3 USB ports. This means if you are just charging the quest 3 from the battery bank and charging nothing else from the battery bank it will stop the quest 3 from losing battery life. Adds an additional 6-8 hours of battery life (in mixed reality games only about 4 extra) on top of the quest 3's 2 hour internal battery.

I'm glad I spent the extra dollars for this compared to other portable chargers. Most do not have C-output only C input. I literally charge my work phone off this and my personal phone and my AirPods. Everyday and I only have to charge the portable Iniu charger once a week and I've never had it go below 10%. I usually just keep it in my backpack but had to just take a cable with me and the charger and it's not bulky at all. I would really suggest this product. Oh and did I mention I always charge my Lost Mary vape's as well. You won't be let down at all.

EIGHT STARS!

Your search for the right battery pack ends here.

I know. It's where my search ended and that was a very long search and I've had this thing long enough to put it through its paces.

Unlike most others which offer a few chintzy lights to help you guesstimate remaining charge, this well-designed unit gives you an actual text-on-screen with the precise percent of charge remaining. So I can give you exact data:

I just got through charging my iPhone 14 Pro and the event opened with the INIU charger at 42% and my device at 15%.

44 minutes later I offloaded the device when it attained 80%. The battery pack residual measured 31%.

I've been using this unit for several months so I believe these data are representative of what you will experience in the long term. (There is fluctuation with Berry and conditions: as the pack gets closer to full discharge it uses a higher percent of charge to get the job done and it takes longer. This event occurred in the midrange so it should provide a good median reference.)

I don't know of any 30,000 mA unit that can approach this level of performance or this number of charges in capacity. Certainly none of the 30,000 units I've tried have come close.

Now here's the killer: when I say it charges fast that's with a regular charger. I got a pair of Samsung 25 Watt fast chargers (which came with a pair of excellent cables included) and the whole pack was only $16. That's $8 each for the best charger I've ever had with a 10 foot cable along with each. (That's here on AMAZON too I'd head right on over there.)

You plug this battery pack into that Samsung 25 Watt charger and it charges up in just two to three hours. Everything about these units is wonderful.

I am happy I bought two of these battery packs. I did that because I require continuous charging capability. Given how quickly they charge and how long they last an inventory of two he's more than sufficient for all of my charging needs.

To be honest I did not know what to expect when I bought these so I grabbed three just in case one broke. So now my phone has a back up battery pack for charging purposes and the two active battery packs have redundancy.

I have absolutely no use for another one. I have no idea what I would do with more if I had them. So I absolutely do not need to buy any more of these. I just ordered two more"¦

I searched for a charging pack that actually worked as advertised and the INIU portable charger is one that in fact works and it charges very well. The other important factor is that the USB-C is an input and output charging port. You charge the INIU through the USB-C and you can also use that port to charge devices that are USB-C. That is huge since more and more electronics are converting to USB-C. Two USB output charging ports are there too so I can literally have 3 devices charging at once. My main use for this is actually for my daughter who plays sports. These days, her days are sometimes 12-13 hours long and for my sanity, I need to know my kids phone is charged. INIU portable charger is it for me.

I am pleased with this compact battery pack. It is very easy to use. I use it primarily to recharge my smartphone. It charges my Samsung S21 Ultra from less than 50% to 100% in less than 30 minutes.

The battery pack conveniently has a feature that displays the percentage of charge remaining when it is recharging another device or when it is being recharged. When the unit needs to be recharged itself, I plug it in at less than 20% and it registers at 100% when I return in a couple of hours. I also can recharge my laptop computer and sometimes more than one device at a time is recharged. I make it a point to carry it with me whenever I have an appointment and it provides consistent power to have the phone power register at 100% while connected for over 4 hours. The last time I took note of this, the battery pack still had about 40% power remaining.

It also has a small penlight which is helpful in low light coditions.

I've experienced no issues with my smartphone recharging since I received this product!

I highly recommend this product!

The only negative comment: the user manual is a joke. The print is far too small to be deciphered without the aid of a magnifier and the instructions are unintelligible if one is able to expand the text size. A phone call to Amazon Support answered my inquiry as to how to recharge the unit and how to connect devices requiring charges. Amazon Support also explained that the flashlight is turned on and off by double tapping the switch on the side of the unit.
