5 stars to me are a bit rare.. But 5 stars!I bought 2 of them for my girls tablets and because my car charging port isnt working. This fits two phones at a time....also you can charge the portable charger and charge one phone or tablet at the same time. It is heavier than a cell phone so just keep it in its thick jersey mesh case for protection incase it falls. It charges really well! And it still has power juice to charge more! Get you one!

So first of all I would like to say that this power bank is a fine piece overall. There are just a few things I would like to do differently, although I don't know if that's the way it's supposed to be or if it's a bug. Oh yes, and first of all: you dont need to say anything more about the actual total capacity, but you shouldnt forget that other power banks from other top brands also dont all have the specified total capacity. So, now to my little criticism: if the power bank still has a remaining capacity of 35%, it automatically switches from fast charging to normal mode. It may be that she is doing this to protect herself. But it can also be that this is a malfunction of my power bank!? I just do not know. If it is a safety circuit, then I would have liked it to ... MoreSo first of all I would like to say that this power bank is a fine piece overall.

If it is a safety circuit, then I would have liked it to be noted somewhere. Maybe that's complaining about a high level, but I think it's worth mentioning because at first, I thought my power bank had a quirk. Like I said, maybe that's the case. Also important to mention: if you want to charge your iPhone via fast charging, then of course you need a USB C to Lightning cable! And if you want to fill up the power bank yourself with a quick charge, then, of course, you also need a USB C to USB C cable and a corresponding power supply unit that supports power delivery 3 ifyou don't already have one, for example, a large power supply unit from Apple. You can of course use any other power supply that supports Power Delivery 3. For example, I can recommend UGREEN's. Is good and cheap and recharges the power bank with 20 watts. Believe me, if you have charged the power bank yourself using a normal USB cable, then you know why I recommend you to charge the power bank yourself using fast charging. Unless you don't care about 6 hours of charging time with a normal power supply. Unfortunately, only a normal USB-A to USB-C cable is included as an accessory. Of course, you can't use it to quickly charge the power bank itself. So think about an extra cable! There is also a small LED lamp that can be connected via USB. So all in all a successful power bank, what I like best is the precise LCD. This power bank gets a very clear purchase recommendation from me. A small interesting note: if you charge the power bank via fast charging via the USB-C port and also if you charge your iPhone, for example, via fast charging via USB-C (USB-C to Lightning cable), a small lightning bolt will appear on the display. If you charge the power bank with a normal USB-A to USB-C cable, this flash will of course not occur because it is not fast charging. From this, you can see very well in which mode the power bank is charging or discharging.

I lost my first one in a car accident, but it was such a good power bank I’m buying another. Unlike some power banks on the market, you CAN charge two devices at once, and charge the power bank while it’s charging other devices. Probably not great for the cells, but for $30 why not? You’ll get your moneys worth.

Bought this on May 30th, started using it June 5. It just died! Foer no reason it will not charge anything. It will receive a charge but will not output any charge to any device. I have tried multiple cords that work on other devices but this power bank has failed. Hopefully INIU of Walmart will send me a replacement.
After buying a handful of cheap battery banks for 3.99 that promise water resistance, solar charging and other gimmicks, only to have them fail within weeks, it's nice to finally have a quality piece of kit to take on my trips. First of all, there's no solar charging on this thing. I have found solar charging to be a silly gimmick that doesn't work with a panel of this size, so I'm glad it isn't there to tempt me. (I kept leaving my other units on my dashboard all day... hoping... only to be disappointed every time when it didn't charge a whit. Best to just charge the thing conventionally and actually have it work when you need it.) Second, this is a massive chunk of metal that is considerably heavier than I expected.

(I kept leaving my other units on my dashboard all day... hoping... only to be disappointed every time when it didn't charge a whit. Best to just charge the thing conventionally and actually have it work when you need it.) Second, this is a massive chunk of metal that is considerably heavier than I expected. If you're looking for a slim, unobtrusive thing, this is NOT YOUR DEVICE. It's relatively huge, and weighs as much as a collapsed star. But it feels like it could survive a fall from an airplane and every surface is armored and robust. I take long trips in old cars to remote locations, and this is perfect for me. It can take a beating and is always there when I need it. Which brings me to my last point. The capacity of this device is, quite simply, MASSIVE. I have been using mostly cheap 5000mAh units from the far east, and they would charge my iPhonemaybe twice if fully juiced. Helpful, but for a four days in the wilderness I would need to bring two or sometimes even three of them. But this things packs the kind of wallop that allows it to be the only charging solution I bring. I recently charged my iPhone four times and my wife's Nokia once, and it still showed the full "four lights" of capacity remaining. I don't know what it would take to run it out of juice, but I haven't gotten anywhere near there yet. So don't expect a delicate, slim little thing. Prepare yourself for some size and heft. But if you're okay with that, this beast is a wonderful performer.
The power bank is easily charged and it easily charges my phone and iPad too - just like it's meant to do! Having said that, it must be remembered that it won't charge devices up to 100%, as it doesn't have an endless supply of power. But, it's absolutely perfect for a long weekend away with heavy phone / iPad usage, or a week away with normal / low use of devices.
Opened the box, read the Ringlish piece of paper that is the poor excuse of a manual. Pulled in to charge as it was supplied with no charge. After 4 hours it was still flashing one light with a distinctive burnt plastic smell in the air. Unplugged it and burnt fingers on the end of the charge cable. The whole device was red hot. Would very likely catch fire if left unattended. I also decided to check the output to confirm if it's putting anything out. It was discharging at 5v 2a and would not engage quick charge which it was meant to support. Either its faulty on that or it' does not support quick charge as stated. I would certainly not recommend buying this as a battery pack, perhaps as a bomb it seems to work far better!
Since mobile phones have barely lasted a day, it has almost become a matter, of course, to carry such a power bank with you. My cell phone, Sony XZ Premium, is extremely power-hungry because of the 4K display, often the battery is already at 50% at noon, although I leave the house fully charged at 7:30. My first power bank from 2011 was a Varta with 3000mAh, far too little, especially only 1A charging current because the cell phone only discharged more slowly. I've had the 10,000mAh Xiaomi power bank for a long time, which is quite enough to get me through the day easily, even if I have the hotspot on and Pokemon go open, it even manages to charge the cell phone at the same time. But when I'm out and about with my partner, she has a Xiaomi Mi 9T, it gets cramped, ... MoreSince mobile phones have barely lasted a day, it has almost become a matter, of course, to carry such a power bank with you.

My first power bank from 2011 was a Varta with 3000mAh, far too little, especially only 1A charging current because the cell phone only discharged more slowly. I've had the 10,000mAh Xiaomi power bank for a long time, which is quite enough to get me through the day easily, even if I have the hotspot on and Pokemon go open, it even manages to charge the cell phone at the same time. But when I'm out and about with my partner, she has a Xiaomi Mi 9T, it gets cramped, and the 10,000 power bank is still not enough for a day. I bought an adapter for my Bosch Pro 18V batteries, because of the higher number of cells, a 5Ah battery corresponds to a power bank with 25,000mAh or a 4Ah ProCore also corresponds to 20,000mAh. I could even have taken additional batteries with me, but unfortunately, the part is quite useless, charging with too little current and only sequentially at the two outputs. So I came up with this product, 20,000mAh should be enough for both of us. The product comes unspectacularly packaged, the accessories include a very practical transport bag, an unfortunately very short USB A to C cable, and an LED light as a gimmick. The power bank is no longer lightweight and weighs around 350g, but still less than a ProCore with a battery adapter from Bosch. I find it very practical that you can charge the device both via USB C and micro B, which makes the whole thing more flexible. Only one power button is built into the controls, but it only turns on the display, which turns itself on again after about half a minute. A 5mm LED is built-in, which can be switched on and off by double-clicking the power button. Because of the limited brightness, this is at best an emergency solution, but it doesn't hurt either. The supplied LED light illuminates smaller areas quite well, which is plugged directly into USB A. From the factory, the power bank had 88% battery and I immediately tried, with the hotspot and Pokemon switched on, to see whether the device was able to charge even with high power consumption. According to the Accu-Battery app, between 500mA and 1A are additionally charged, i.e. the mobile phone battery will be full in 5 hours despite the high load. It's a little less than with my smaller power bank, but still significantly better than the Bosch solution. Even with two connected phones, the power bank manages to charge both of them, which was also the goal of the purchase. I can recommend this power bank for my use of going monster hunting with two people, the weight is just about OK for the jacket pocket, but you don't have to take two with you. And for the coming festival season, it should even be possible to get by with the power bank together for 2-3 days without a socket.
I bought this because we accidentally drained our car battery charging various electronics on a four day camping trip; 2 iPhones, an iPad and a small LED lamp that we use quite a lot, especially overnight.At 5.3 x 2.8 x 1 inch, the INUI power bank is compact enough to put in a glove compartment or stow under a seat. It's a little heavy at 3/4 lb, but I am not going to be hiking with it.It comes with a USB-C to USB-A cord to charge the power bank, The cord is 12 inches long. There is also a case. It's a snug fit, but you can get the INUI power bank and cord into the case. The case provides a bit of cushion, but its mesh so its not going to protect the unit from liquids. But you want to keep a lithium battery ventilated and not overheat it.My first test of the ... MoreI bought this because we accidentally drained our car battery charging various electronics on a four day camping trip; 2 iPhones, an iPad and a small LED lamp that we use quite a lot, especially overnight.At 5.3 x 2.8 x 1 inch, the INUI power bank is compact enough to put in a glove compartment or stow under a seat.

But you want to keep a lithium battery ventilated and not overheat it.My first test of the unit:The INUI power bank arrived charged to 53%. I plugged it into a small 2.1 amp USB-A charger; one of those little cubes that plugs into a wall socket. It took about 4 1/2 hours to charge the power bank to 100%. When my iPhone SE 2022 was down to 20% charge, I recharged it through the USB-A output port of the power bank. The iPhone charged to 100% in 2 hours, and the power bank charge fell from 100% to 92 %. (Note that the iPhone SE 2022 is one of the smaller iPhones.) That seems pretty good given the specs on the website for charging bigger phones.This looks promising for keeping our iPhones charged for a few days, and give us a little piece of mind that we aren't draining the car battery.
I got it for my dad for father’s day and he loved it. He already had one but it was not as fast and it was falling apart. This one is a little heavy and thick and long which is okay because he won’t travel too far. Has a flashlight and three ports.
