Same here, I have chosen this xiaomi 10,000mAh out of all my portable chargers to be my to-go powerbank. The internal LiPo holds more energy than 3x high capacity 18650s because of the much higher operating voltage range compared to Li-Ion.
I’m about to receive the new Xiaomi 20,000mAh with QC3.0, which also uses LiPo cells, hopefully the same cells from this one. It should be very interesting to see how much better it performs vs the older model with 6x 3,350mah 18650 cells.
They are really nice. I especially like that with a double click of the power button, it’s in the always on mode so it won’t shut down when charging ultra low current draw devices like the Jetbeam Mini 1, etc. You’ll know when you’re in that mode because the 4 charge LED’s will flash one at a time. To exit the always on mode, just single click the power button.
Just a guess, based on testing 20 powerbanks :
the Xiaomi will score marginally better, as it is a LiPo-cell as opposed to the Anker, which uses 3 18650's (based on it's dimensions and power rating.) LiPo based powerbanks always score a little bit higher in my experience.
I put purchase date labels on mine to keep track of them. So far the one I purchased in May of 2015 is still going strong after extensive use. I’m very impressed with this company.
I got the power bank, but it’s not working properly. It doesn’t connect to any device and when I’m charging the power bank, the one dot keeps blinking for few hours and then skips to all 4 dots. When I plug in my phone or any other usb device, nothing happens. I think that the whole pcb is broken. Do you know if I can get that pcb alone anywhere?
I would like to know something about how much Quick Charge changes the usuable capacity (charging cycles on mobile phone)? The main idea of mine to have a powerbank is to have maximum times(cycles) %0 to %100 battery charging on mobile phone when you are away from AC
Mi Powerbank’s capacity is 10,000mAh @ 3.85V so it means if the mobile phone is 3,85V and has 3000mAh battery it can be charged nearly 3.x times but if the mobile phone is 5V and 3000mAh so it can be charged aproximately 2.x times.
So the quiestion is; Quick Charge 2.0 is charging at 9v and Quick Charge 3.0 at 12v and at these rates how many times can we charge a mobile phone which supports Quick Charge with a battery of 5v 3000mAh?
I know this question is several months old but I will explain it quickly anyways if anyone needs to know.
When trying to figure out how many times will a powerbank charge a phone, it is easier to ignore capacity and voltage entirely and focus only in energy. By looking at the closest discharge rate in the chart, take that Wh output rating and divide it into the Wh required to fully charge a phone, that’s how many times it will charge it.
Lets say you have a phone that charges at ~9V 1.5A, and using a power meter you know that it takes 18Wh to fully charge. The xiaomi has a output Wh rating of 34Wh at that charge rate, so it will charge the phone almost 2x times.
Rated capacity is how much it has, output energy is how much you get. This is why discharge tests are important when reviewing power banks.
