Portable Charger Power Bank 24000mAh Huge Capacity Battery Pack with LCD Screen, 3 Inputs 2 Outputs Backup Battery Phone Charger Compatible Smart Devices Tablet Android Phone and Other Cellphones

I bought this on October 8 2020. It is now May 31 2022. I had this in my house for the most part until about 6 months ago. I then started storing this in my van (in Florida) to have an emergency power supply. This lasted nice for awhile. Then about a month ago it became completely useless, no slow aging process. It will show charging at 100%, but plugging it in gives about 5 seconds of use before it's at 0%.So, for the money, $22 or whatever, it was great.I decided to take this apart to see what batteries these were, to see if it was worth repairing or if I should just purchase a new one.Well, I desoldered the 2 batteries from the unit and I see these are labeled as 7565121 batteries. I do a search and see that 7565121 are 8000mAh batteries. So, 2 x 8000mAh is 16000mAh.I don't know why this is marketed as 24000mAh. It quite clearly isn't. That's just wrong.Nevertheless, for the $22, it's a great price even if you only get just over a year of use.

Let me tell you the reason why I decided to get a Power Bank. A few years ago at a Holiday Dinner event, 7 family members, (including myself) all had our cell phone and we all ended up having to have them charged. It seemed at the time to me that it just wasn't right to go to one person's home and use up that much power for so many cell phones. :)I had purchased a previous power bank but very seldom used it. I gave it to a friend who was traveling back and forth quite a bit and then I found 5D Diamond Painting kits.I found that I needed some source of power that could be plugged in to an ultra thin light tablet so that I could see more clearly where to put the beads with the corresponding color code. I decided to get this Power Bank.I absolutely love this! When I use this, I usually have the power bank plugged in to the light tablet, as well as having my Samsung A20 Cell phone plugged in charging at the same time. I can use this Power Bank in this way for hours. It will completely power the light tablet and fully charge my cell phone quickly to 100% and usually I still have around 77 % Power Bank charge left showing.When I work on the Diamond Painting kits, I literally am working on them for as long as 4 or 5 hours at a time, which includes getting up and moving around, getting coffee, things like that. Of course I turn the light tablet off while I am doing that.I could not be more pleased! This performs wonderfully and consistently.The price is very reasonable and the charge lasts a very long time. I have never gotten the charge down below 50% at any given time when I have been using it.Get it, you will be glad you did!

This battery pack says it’s 24,000mah, however I only get maybe 1.5 full charges on my iPhone 12. Meanwhile my other battery pack labeled as 10,000mah I get about 3 full chargers. Also, recharging the battery takes forever, almost 20 hrs to get to 100%, and I’m not sure it is even 100% cause I looked at it and it said 75% then a few minutes later it read 100%.

I just got this yesterday, and it works great. It was charged to 26% out of the box (the percent shows on the LED if you press the button), so I charged it. It took about 12 hours to get to 100%, which would be equivalent to taking 16 hours if it was fully discharged (at 0%). That's actually faster than what I would have expected, given its high capacity.My iPhone was at 75% and didn't really need a charge, but I figured I would test out the charging speed of the power bank anyway. It ended up taking about the same amount of time as charging through the wall outlet, again, what I would have expected. When the iPhone got to 100% charge, the power bank still showed 99%, which is great. So 1% of the power bank capacity was used to charge about 25% of the phone.One nice feature I wasn't aware of was that pressing the power button twice turns a flashlight on/off. It's not a very powerful light, but the feature could come in handy.The case is sturdy, made of a very hard plastic, and seems well made. There are 5 various input/output ports and an LED. The power bank allows for simultaneous charging of two devices. It also comes with a 16 inch USB cable that I wasn't aware of since it was hidden under a cardboard insert in the box.This power bank seems like an excellent value for the money. I'll update the review if I have any problems. I will also be using it to power a lens heater used to prevent dew on a telescope or camera lens when doing night sky photography.

This battery pack looked too good to be true but based on a friend’s recommendation I bought one to try. Love it!I have several RavPower and Anker packs in the 6,500-17,000mAh range. But the cost quite a lot more per 1000mAh than this pack.Pros:Huge capacity of 24,000mAhCan charge my iPhone7 several timesLED display of remaining percentage of chargeCan be charged via Lightning or micro-USBSame size as iPhone 7 so easy to carry with it(3 times as thick)Very low cost for performanceSeems well made and works greatCons:One USB port is only 1Ah, and the other is 2.0Ah. Works OK but ports are not labeled as such. Why not two ports of 2.4Ah? AtLeast the digital display does indicate the output amp-hours being used.I bought two more of these packs and now use them the most often. The 24,000 mAh capacity is great if you are traveling or camping and rarely have long enough access to a wall or car USB charger. Or for extended power outages, emergency hospital stays with a family member, etc. great to be able see exact percent of capacity remaining and not just three or four LEDs. And being able to charge via iPhone Lightning or standard USB cord is super handy for a family with lots of Lightning cords in cars but not always a USB.I highly recommend this battery pack for its capacity, quality and price. About the same price as a RavPower 6,500mAH pack but more than three times the capacity and more versatility.
