Samsung Galaxy S21 Ultra, S21+, and S21 and the S20 Ultra/Plus series are premium flagship phones with huge 4000-5000 mAh batteries with support for 45/25-watt PPS and USB-C PD 3.0 charging. Best portable chargers for Samsung Galaxy S21 and S20 Ultra/plus series as well as the new S22 series should ideally support 25-watt PPS USB-C fast charging, get charged fast via Samsung 25-watt chargers, and have adequate batteries to charge the large batteries of the newest S22 series phones as well. Here is our pick of best power banks for Samsung S21 5G & 4G series and the S22/S20 series-

Some chargers in the article are 18-watt even as Galaxy S21/S22/S20 series phones support 45 or 25-watt maximum charging speed. This is not necessarily a disadvantage as high voltage/high current charging causes greater energy-loss and gives less power backup from the same battery compared to slow charging. 18-watt is still a good balance of charging speed and battery-backup. Even Samsung now only offers real speeds of around 25-watt in the latest S22 series. Apple too, limits charging speeds to 20/18 watt in iPhone 13/12/11 series.
