It is a very good power bank and it is totally worth the money. I am using this for now anlong time and i have put very load on it and the only problem i have with it is ,it takes minimum 6-8 hours of charging usually I just plug it in while night and it charges but sometimes it can be a problem. Rest everything is very good the build quality,the charging speed and the looks also personally I really love this product.😁 If you are going to buy it go for it you will not regret,the packaging was also very excellent.

Good powerbank at this price. Not so compact as you expect from a 20000mah powebank. Appearance is very sleek, atleast in all black varient. No wireless charging. Battery life also very good as it uses the more premium Lithium ion battery. The only downside is the size and weight, it is always going to be bulkier than your phone and also don't charge laptops cause it's 33W. So order it if you want to use it as plug and leave cause it's very big and heavy to carry in your hands.

It's a great product. It's charging speed is also fascinating. It helps to charge phones rapidly. In this price segment it's beyond and far better than 'good'. It's looks also good. Three ports are available two fast charging and one superfast charging. It's a bit heavier but good for travelling. Capacity is 20000mah.

Nice power bank. Takes a while to charge but charges phone quickly

Xiaomi 4i Truly Dilivers 33Watt Output on Both USB PD protocol and USB Quick Charge Protocol, it also outputs 20V output.. that is great, it charges many Type C supported Laptops too.. Type C port only supports 33Watt output, and Type A support 18 watt QC output only Input also supports Charging of powerbank upto 27 watts... The output quality is good, Acceptable Ripples, no dangerous voltage spikes.. no heating at all... So its a long lasting powerbank.. 5 starts

Very good, been using it for about 2 years. Works flawlessly and looks really good too. Not bulky, and charges a phone about 3 to 4 times

This is a high-quality product, and I truly appreciate it. It is indeed true that it charged my Xiaomi phone rapidly. However, if you want your power bank itself to charge quickly, you must use a Xiaomi 33W charger. I also tried using a Vivo charger, but the charging speed was slow; even when connected to a Vivo phone, it charged slowly (at around 10–15W). (Your experience may differ; I am simply sharing my personal experience with you.)

The Xiaomi Power Bank 4i 20000mAh is definitely worth it. The build feels rugged and durable, and the backup is excellent with long-lasting power for both heat and cold conditions. The 33W super fast charging with PD works smoothly and charges devices quickly. It is slightly heavy, but that is expected with such a high-capacity battery. Overall, a solid choice if you need dependable backup power on the go.
