Review: The Product - Very good and useful product also fast charging and good battery life easy to carry and good looking but little heavy overall good product for. The price
Review: Good one from MI - I have previously used 20000mah from MI the first one ever released and that’s working till now. As my brother is using it, so, I decided to get another one for me. So, which brand to go for? Well why not the same one I’ve been using. So, I decided to opt for this. The power-bank comes in a simple packaging with a scratch code on top to verify the product’s authenticity and ghat if it’s been used previously l. Mine was a new one with all the things intact. In the box you get a power-bank 20000mah and a usb type to type-C cable that is quite short, don’t expect much. The main highlight is the power-bank which has 2-USB type A, 1 USB type C and 1 micro USB type. Micro USB only supports input while USB C can be used for input as well as output. The type A can only be used for output. The max output is 18W and supports fast charging. 1. Build Quality (4.5/5): Aluminium body looks sturdy and durable. 2. Charging Time of Power-bank (4/5): Around 7 hours from 25watt charger I used. Although I think 18W is the max input it supports. 3. Charging Output (4/5): Max 18W fast charging and yes it can charge iPhone and Samsung phones if you are worried. No issues there as I have tried it on my devices. The output may decrease if you charge multiple devices simultaneously. 4. Packaging and condition (5/5): Received a brand new product in working condition and a genuine one in a good packaging. So, KUDOS to that! # You can simultaneously charge the power-bank while charging the devices. But, there might be an issue if you charge two devices that supports super fast charging like when I tried to charge my tab s9 and my phone S23-FE simultaneously when the power-bank was in charging, my S23-FE stopped charging after a few seconds. Although, when I tried it while connecting tab and iPhones it was working without any issues. And yes, this is only during the charging devices while charging the power-bank at the same time. # 3 output ports (2 type A and one type C)and 2 input ports (micro USB and type C). # 12 layer protection against short circuit. Imp to notice: 1. For charging low power devices like watch and earpods, you can switch to low power output mode by fast clicking the power button twice and holding it until the light start blinking one by one. That is low power output mode and it’s a really nice addition. Just click the power button once to switch back to normal mode. 2. Can switch off the power-bank too, now, that’s something to watch even though I don’t know how long am I gonna use it. Just tap and hold power button once for 10seconds and then you will see the all the lights blink at the same time for 10 times and then it’s off. So, overall for me as I have previously used the Mi power bank, I hope this one lasts as well. I grabbed it at ₹1899 in great Indian festival. But, I have seen price come down to ₹1699 after I had bought it. So, keep an eye for the offer for the lower price. Overall a good buy: 4.5/5
