Super convenient small size for carrying in a pocket. Does fast PD charging. However, I'm not sure it carries as much charge as it claims. The percentage goes down pretty quickly as you're charging your phone. But overall, I'm happy with it.
If you look at the bad reviews, you can really see a bunch of people giving their opinions on things they don't understand.
Many people are complaining that this does not actually have 5000mAh because it doesn't fully charge their phone that only has around 4000mAh.
First of all, almost all battery manufacturers provide a mAh rating based on the nominal voltage of a lithium ion cell, 3.6-3.7v. 5000mAh at 3.6v is 18Wh. The thing is, your phone doesn't charge at nominal voltage, it charges at 5v or more depending on how the power bank provides the power. Most iPhones and Androids charge at 18 watts or more these days. Mathematically, that 5000mAh capacity becomes 3600mAh when charging at 5v, and 1500mAh when charging at 12v.
Watt-hours = Ah * voltage. You can figure out the general capacity at each voltage if you know what voltage your phone is charging at. The power bank itself even lists that at 5v, the true capacity is around 3100mAh instead of the 3600mAh we calculated earlier because they account for energy loss. Charging from one battery to another is going to experience energy loss in the form of heat.
Unfortunately though, I don't believe you can select the wattage at which you charge your phone. Most modern phones these days charge at 18w or higher, which means the voltage will be higher and the battery will drain fast. This thing will most likely only give a battery boost to a phone and likely will struggle to charge a phone from 0-100%. The power bank is still immensely useful due to its size. It's small enough to bring with you in a pocket, day bag, or purse. This is not something you bring with you for a multi day adventure. This thing will likely give your phone another 80% of charge. If you need more than 180% of phone battery and you cannot find an outlet within 24 hours, you should either replace the battery in your phone or bring the right size power bank for your multi-day adventure. This size is more than enough for day trips. Bringing a bigger battery that can charge your phone multiple times is just going to weigh significantly more for no reason at all. It's like bringing a 5 gallon water jug to run errands. You are not going to use it all before you get home and all that extra just weighs you down.
Tdlr; Iniu is not lying about the capacity. This thing is meant as a battery boost to your phone. Great for day trips when you need just enough to get to the end of the day where you have an outlet. If you can't get to an outlet in 24 hours, you brought the wrong tool for the job. Due to the laws of physics, a battery of this size will not be able to charge most phones to 100% at 20watts multiple times. Use common sense.

what if you get a cable that only slow charges at 5v?
what if you get a cable that only slow charges at 5v?
If you can find a USB-C to USB-C cable that doesn't have the Power Delivery protocol, then it should charge at a lower wattage. I've never actually seen one though. If the power bank had a USB-A port on it, then a USB-A to USB-C cable would work as USB-A does not have the pins for power delivery negotiation.
The only potential solution would be very janky. Buy a USB-C (male) to USB-A (female) adapter and plug the C end into the power bank. Then plug a USB-A to USB-C cable to the adapter. It would look something like this:
Power Bank C Port---> C-A (adapter) --->A-C (cable)--- C port on phone.
The adapter and the A-C cable definitely don't have the pins required for negotiation of higher wattages.

You forgot the fact that higher voltage means less amps for same draw. The higher the voltage, the lower the amps it needs to draw for the same watts power output. 5V at 3.6A is the same power draw as 9V at 2A for example. Both will draw 18W of power, but the 9V will need 0.55x the Amps to run 18W for an hour. In the end, the actual battery consumed will be the same.
So even if technically the mAh is less for higher voltage, the draw is equivalently lower. 5V will pull 3600 milliAmps in an hour, 9V will pull 2000 mA, and 12V will draw 1500.
Watt hours is a much more useful metric for this reason. Because Watts is the actual power consumed. That's why your power bill is measured in watts and not amps or volts.
Weird, I'm a Prime customer. When I first opened the link to the product it was showing as $26.99 and a total of $13.76 in my cart, same as someone stated above. I deleted it from my cart, went back to the link and refreshed, and it then showed the item at $22.49 and the correct total with tax for me of $12.23 in my cart.
This was why I bought the battery--fantastic for Apple Watch charging. I keep this in my work bag to recharge the watch at my desk as needed, or on road trips. Only uses ~13% of the battery to recharge the watch. It does appear to support the faster charging as well. Cheaper than buying another watch charger and pretty convenient for what it is.

Agreed. I did the voltage math equation to show how the mAh rating doesn't really mean much, I guess I wasn't very clear about it. Watts and Wh are far more useful because of this reason.
When I said the battery will drain fast because voltage will be higher when charging at 18w, I meant that it will be higher than the 3.6v they used to calculate 5000mAh so that 5000mAh is a fairly useless number. Also, technically, charging at a higher voltage will result in lower capacity due to the inefficiencies of the boost converter.
Still, kind of sucks you cannot choose to charge at a slow 5w (5v 1 amp). The Power Delivery protocol will negotiate a higher wattage no matter what.
