I bought these years ago when I was working outside and it was cold. I have a heated vest and these batteries are incredible. I charge them a year ago. I have not use them and they still have a full charge. I can use them now with my new backpack and Charge my phone. These batteries are built the last and our good quality. They look good their Portable and the size of them is manageable unable to charge my phone very quickly with these batteries. I suggest getting these if you have a backpack or a heated vest that supports a charging port.

I love these! Very easy to use, have a large battery capacity and charge my phone, iPad and other devices quickly. I keep on in my backpack for train rides, so I can watch movies on my hour train commute and for whenever I am out and don’t have access to an outlet. The size is perfect, taking up very little room in my bag.

The batteries are great. They hold a huge amount of energy and give lots of charges. But read the details carefully about input versus output.INPUT has slots for both Micro-USB and USB C. The ports are only for power input to the battery, and don't output power. The USB C port can use fast charging input to charge relatively quickly. They store a huge amount of power, and can take many hours to charge if not using fast charging.OUTPUT goes to two big USB square plugs. It does not output a fast charge. You can power any two items with standard big square USB plugs. It includes a cable that is big square USB plug to Micro-USB, and another cable that is big square USB plug to USB C standard charging speed output. You can instead plug any big square USB cable into the battery and it will output regular USB power. Each battery holds a huge amount of power. If it doesn't turn on automatically, hit the button to turn it on. It has an auto-off when the device stops drawing power, which is pretty common these days, or you can push the button to turn it off. It has the typical 4-LED panel to indicate remaining power.Critically:* It will not OUTPUT to the USB C port. If you have a USB C to USB C cable the battery will only INPUT power to the battery. If you plug it into a laptop or Nintendo Switch or phone through a USB-C to USB-C cable, it will drain the device to charge the battery, never the other way around. Several one-star reviews talk about the batteries draining their device, they likely used a USB C to USB C cable.* It will not OUTPUT for USB C fast charge. It will only output to the slower, standard speed.As long as you are fine with standard speed output, these are great high capacity batteries.

I needed something small yet with enough power to power my amateur radio DMR hot spot while operating mobile. The 2 pack was nice as I just plug in the 2nd one if I run out of power.

I have been using these power cells to supply power to the pumps in my bird baths. So far, they have been able to supply power continuously for about 2.5 days. Depending on the charger used, it takes about an hour to recharge.

I ordered these a few days prior to the huge storm in Texas that wiped out our power for days. They arrived in time and I charged them. On the morning the power went out and my phone got down to 30% I plugged it into one of them. All of a sudden my power was down to 3% - 2% - 1% and in a matter of seconds it powered off. I didn't have time to text my family to let them know my phone had died. I tried it plugging it in again but my phone ignored it. I tried to power my phone on several times and it tried to start and then immediately powered off. The roads were one big sheet of ice and my family became very concerned as it was my only source of communication without other power.Before I wrote a scathing review I wanted to contact Miady to see if I had done something wrong. They only had one tiny sheet of paper with info in the packaging and half of it was in Japanese. I could find no website for them although the info did give a contact email. I emailed them and have waited over a week with no response. I suggest if you buy these to definitely try them out before you need to use them as they certainly did not work for me.BTW - my phone was able to charge with my car (once I could pull it out of the garage) and once the power went back on it charged just fine in the house.

These power banks charged from empty to full overnight and provided power for my teen's device for 3 days (we were in an area with limited power outlets). They're easy to carry and didn't get too warm.
