Overcharge, overheating protection hai → safe use 👍
Excellent power bank with strong battery backup. The 20000mAh capacity easily charges my iPhone 3–4 times on a full charge.Build quality feels solid and premium. Charging speed is good, especially with Type-C fast charging support. LED indicators are helpful to understand the battery level.It is slightly heavy, but that’s expected for this capacity. Perfect for travel and daily use.Overall, great value for money!

Great product but very big.
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 doesn’t heat even if u use it outdoor. But little bil heavy and bulky weights around 450 grams
I am highly satisfied with this product. Its the best powerbank i ever found cause it doesn’t heat even if you are charging ur phone or even charging this powerbank. Its weight and size is a drawback its weight is around 450 grams im not sure about the exact weight but itz somewhere around this figure if u don’t carry a bag with u it may cause trouble but if u carry bag like me there will be no issue. As a college student its perfect for me. It can pass 2 days if it’s full charged. It takes around 4 hours to full charge. At the end product is fabulous ( full paisa vasool)

Quality Product, Must Buy
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 onlyInput 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

After 3 months of using.
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.

Rugged and Reliable Backup
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.
