Decent Power Bank with Good Capacity, But Has Its Quirks
The Xiaomi 4i 20000mAh power bank delivers solid performance overall, but it’s not without some drawbacks.PROS:1). High Capacity & Fast Charging => The 33W PD fast charging works well for most devices, including phones, tablets, and earbuds. It can charge my phone multiple times without issue.2). Triple Output Ports => Useful for charging multiple devices at once. The combination of USB-A and Type-C ports is convenient.3). Type-C Input & Output => Charging the power bank with Type-C is fast and efficient, which is a big plus.CONS:1). Bulky & Heavy => It’s on the heavier side, which makes it less travel-friendly. Not ideal if you’re looking for something portable.2). Plastic Build Feels Basic => The build quality is okay, but the plastic body doesn’t feel as premium as some other options in this price range.3). Heating During Fast Charging => Gets slightly warm during fast charging, especially when charging multiple devices.---FINAL VERDICT =>If you need a high-capacity power bank with decent fast-charging support, the Xiaomi Power Bank 4i is a reliable option. However, its bulk and basic design may not appeal to everyone. A balanced product overall – not perfect, but dependable.

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 thepower-bank while charging the devices. But,there might be an issue if you charge twodevices that supports super fast charginglike when I tried to charge my tab s9 and myphone S23-FE simultaneously when thepower-bank was in charging, my S23-FEstopped charging after a few seconds.Although, when I tried it while connectingtab and iPhones it was working without anyissues. And yes, this is only during thecharging devices while charging thepower-bank at the same time.# 3 output ports (2 type A and onetype C)and 2 input ports (micro USB andtype 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
