Nice powerbank does the job also support fast charging on Samsung phones. But with time it's charging quality or something degrade cause at initial it work well charge the battery even while using phone but after some months it can't charge the battery while using. The charging percentage goes slowly up while using or stay at same percentage on which you plug the Powerbank. The top material is good for price but not as strong as metal body provided by Xiaomi in 10000mah models they are so strong. And it is a bulky power bank feels heavy weights nearly two smartphones. The c to c cable is decent but not as good as braided ones but support fast charging. And you can also use it for charging powerbank. Only major flaw is if there was two type C ports it would be good. But still serves the purpose and done the job well then expected. One thing more it heats while getting charge and also gets the charger a lot so use a GaN charger or avoid over charging though it has protection but prevention is better than cure.

I’m quite satisfied with the Xiaomi 20000mAh Power Bank 4i. The build quality feels solid, and the 20000mAh capacity is more than enough for daily use and travel. It provides good charging speed and can comfortably keep my phone powered throughout the day. The power bank is well-designed and feels reliable. I also like that it has multiple charging options, making it convenient when charging different devices. Overall, it’s a good power bank for anyone looking for a reliable 20000mAh option with good performance and value for money. Recommended for daily use and travel.

I have been using the Xiaomi Power Bank 4i for regular day-to-day use, and overall I am very satisfied with its performance. The 20,000mAh capacity is its biggest advantage. It provides plenty of backup for phones and other small devices, making it especially useful while travelling or during power cuts. The build quality feels solid, and the multiple ports are convenient when charging more than one device. The USB-C output provides good fast-charging performance with compatible devices. In my testing, charging speeds were noticeably better than a basic 10W power bank, although the actual speed depends on the phone, cable and charging protocol. The advertised 33W output should therefore not be interpreted as 33W for every device. Recharging the power bank itself can take several hours depending on the charger used. Using a compatible higher-power charger is recommended if you want to take advantage of its faster input capability. The only minor downside is its weight and size, which are expected for a 20,000mAh power bank. Overall, this is a reliable and versatile power bank with good capacity, solid build quality and fast-charging support. A good choice if you prioritise battery capacity, reliability and versatility over the absolute fastest proprietary charging for a particular phone. Pros: 20,000mAh capacity Up to 33W output USB-C fast charging Multiple ports Good build quality Useful for travel and power cuts Good value for a high-capacity power bank Cons: Relatively heavy Full recharge takes several hours Maximum charging speed depends on device and charging protocol Overall: 4.5/5

Excellent performance and reliable battery backup. This power bank exceeds expectations. The fast-charging capability works flawlessly with my devices, and the build quality feels premium and durable. I can easily get 2 to 3 full charges on my phone before needing to recharge the power bank itself. The LED battery indicators are also very accurate. Great value for money.

This is indeed the best powerbank, I had ever used Battery backup is great as it can 5000 mAh phone 3 times full, considering the environment condition suitable not too hot or cold and charges also at 28~30 watts and the outuput is also same You can charge macbook with this also as I did charge. It definitely feels bulky but the size and durability is fine It is also flight safe as of now One issue I face you cannot use it while charging the powerbank because it has one Type C port. In the box you get a Type C to Type C cable and powerbank

Very very good product without hesitation buy this product

Good power bank. Able to charge upto 3.5 times, my 5,000 mah devices. supports fast charging. Is heavy but is expected out of this capacity power bank. Doesn't heat up when charging devices much. Slighlty heats when charging itself, but again not much. Has a matte finish. Could be carried in a small bag, not very big. Supports C to C (one port), USB ports (2 ports).

Good but heavy
