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

Some chargers in the article are 18-watt PD even as Galaxy 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 besides wearing down the phone batteries. 18-watt is a good balance of charging speed and capacity. Even Samsung has discontinued 45-watt charging and now only offers 25-watt in the latest S21 and Note 20 series. Apple too, limits charging speeds to 20/18 watt in iPhone 12/11 series.
