Xiaomi Power Bank 4i 20000mAh 33W Super Fast Charging PD

Worth The Money.

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.

Excellent 20,000mAh power bank with fast charging

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 capacityUp to 33W outputUSB-C fast chargingMultiple portsGood build qualityUseful for travel and power cutsGood value for a high-capacity power bankCons:Relatively heavyFull recharge takes several hoursMaximum charging speed depends on device and charging protocolOverall: 4.5/5
