I needed a larger power brick that was at least over 10,000 mAh, as my phone is 4380mAh alone. So, a single charge would drain a standard brick. So, I opted to give this a try. As far as real use so I was able to charge my phone with a 18%. I got a full charge out of it and then I moved on to a table that has 7040mAh. The tablet was drained to 0% and it managed to get it charged back to 29% and simultaneously charging a gamepad as I was still playing the game pad maxes out at 1050mAh. However, the Power brick was down to a single dot left. And if you know this power brick has a indicator of four green dots. So we have to extrapolate how much power is used based on four dots.
To calculate how much power I had left over. mAh is explained as follows:
The capacity of batteries is indicated as XXXX mAh (milliampere/hour).
The formula for calculation is as follows:
Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour)
E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 milliampere/hour.
If you insert this battery into an appliance which consumes 100 milliampere current continuously, the operating time of the appliance will be around 20 hours mathematically. However, this is just a guideline since it varies depending on the performance of the appliance or the conditions it is used in.
Overall this battery pack is bulkier than most but has a decent power supply if fully charged for when you're out and about. If you have a back pack or a good way to stash this power supply away until you need it. The biggest plus of this battery is the fast charging capability, though I was only able to achieve good charge speeds using a type C to type C connection. The cable supplied is a standard USB A to Type C that didn't do the trick for me and my phone so I used it to charge a game pad. Always try to learn your devices mAh so you have a better understanding of how much you're actually draining.
I like it but, it's fat and bulky to store than most. The overall usability is there but if you don't have a good way to carry it you'll hate it.

I received this TW brand portable charger and immediately noticed how huge it is! It's about as big as an iPhone max but about an inch thick. Additionally it's not very light, however, when you're desperate for battery power you'll take anything! Portability is probably the biggest issue I have with this charger, if you're gonna throw it in a suitcase or perhaps a larger purse then it's a non-issue, however if you think you're going to put it in your pocket, think again. I do like that it has three different charging ports so I can charge 3 things at once as long as one side is USB or or C. The value is definitely there, at this price I would say get one but if portability is your biggest concern then I would say look elsewhere. Other than that the battery itself lasts quite a bit, sometimes it seems to charge slower than other times not sure what that's about. It's made of high-quality plastic and seems like it will last a long time.

A lot of charge capacity, moderately compact, one fast charge port, but no special features
Reviewed in the United States 🇺🇸 on January 20, 2023
This power bank has a lot of capacity at 20,000 mAh. It also has two USB A and two USB C ports (one fast charging). The size is relatively compact relative to its capacity. Some of these power banks offer features like a led flashlight, wrist strap, carrying case, or digital display. The only feature on this device, beyond its core charging capability, is that it has led lights to indicate the remaining charge in the battery. I would recommend if you only want a basic power bank with a lot of capacity but don't need any extras.

This power brick is massive. Way bigger than I thought with it being a 20k mAH. It will fast charge however and has 2 USB connections, a micro USB, and a type C connection. Tested on a galaxy s22 ultra. It works great. As far as portable the size makes it very awkward and it is a bit heavy as well.
