Samsung Galaxy S20 Ultra, S20+, and S20 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 S20 Ultra, S20+, S20 should ideally support PD fast charging, get charged fast via S20 series chargers, and have adequate batteries to charge the large batteries of the S20  series. Here is our pick of best power banks for Samsung S20 5G & 4G series –

Almost all 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 Note 20 series. Apple too, limits charging speeds to 18/20 watt in iPhone 12/11 series.

Wireless power banks are very useful for constant use of phone over the day without repeatedly keeping track of the battery and plugging it in chargers. Aukey 20000 Wireless PD is a compact, light and fast-charging wireless+wired USB-C PD power bank for Samsung Galaxy S20 Ultra, S20+, S20 phones. In wired mode, Aukey 20000 Wireless PD works just like any other 18-watt USB-C PD power bank and gives two charges from 30% to 100% to the S20+ at charging speed of zero to 50% in about 35 minutes (30 mins for S20).

Best wireless USB-C power bank for Samsung Note 10 Plus
Aukey 20000 Wireless PD can be used as a landscape mode phone stand while wirelessly charging

In wireless mode, Aukey 20000 Wireless PD can charge Galaxy S20 Ultra, S20+, S20 at a speed of 10-watts – this is fastest by any wireless power-bank and gives about zero to 50% charge in about 1 hour 15 minutes for the S20+. It has a sleek modern design and can be used as a phone stand in landscape mode while charging wirelessly. Aukey 20000 Wireless PD also gives wireless fast-charge to wireless charging supporting iPhones at 7.5 watts.

In wireless mode, the charging efficiency of Aukey 20000 Wireless PD drops by minimum 30%. This means you can expect about three charges from 30% to 100% for the S20+ when charging in wireless mode. This is due to unavoidable loss of energy in all wireless power banks or charging pads. We, therefore, recommend using only the wired mode when you do not have easy access to power outlets. Wireless mode is best used when the power bank is plugged in or when you are close to a power outlet (such as at work or when connected to in-seat USB power outlet in flights).

Aukey 20000 Wireless PD also supports 15-watt Samsung Adaptive Fast Charging for Samsungs S10/S9/S8/S7 etc. and Note 10/9/8 etc. and charges most older Samsung phones fully four times in wired mode. It will also fast-charge latest iPhones 11, 11 Pro, 11 Pro Max, SE 2020, XS, XS Max, XR, X etc. from zero to 50% in 30 mins.

Aukey 20000 Wireless PD can be charged in about 6 hours with Samsung Galaxy S20 Ultra, S20+, S20 chargers. A useful feature is that, you can use the power bank to wirelessly charge phones while charging the power bank.

The power bank weighs about 8.3 oz (235 grams) with dimensions of 6 x 3 x 1 inches.  The design is a bit glossy and we would have preferred a bit more under-stated design.

Pros

  • Zero to 50% in 30/40 minutes for S20 Ultra, S20+, S20
  • Wired mode fast charges the Samsung S20+ four times from 30% to 100%
  • Wired mode fast charges all latest iPhones – iPhone 12 & 11/XR/XS/X/8/8+ zero to 50% in 30 mins.
  • Wireless mode charges the Samsung S20+ three times from 30% to 100%
  • 10-watt wireless charging support (7.5-watt for iPhones and 5-watt for old iPhones such as iPhone 8)
  • Also wirelessly charges other Qi compatible phones such as LG ThinQ, Pixels etc.
  • Wirelessly charge phones while charging the power bank
  • Can be recharged in about 6 hours by the S20 series chargers
  • Can be used as phone stand – very handy while charging wirelessly at work or in flights

Cons

  • Can be used as stand in landscape mode only. The portrait mode is used by most users and is easier for quickly picking up phone to receive calls etc.
  • No USB-C to USB-C cable included. It comes with a USB-C to USB-A cable that is useless for wired fast-charging for Note 10s. S20+ gets fast-charged via USB-C/USB-C cable only, so either you will have to use the cable that comes with the phone for use with the power adapter, or buy a new one.
