Dual PD port chargers are very handy as they can fast-charge BOTH your phone and PD powerbank at same time.

A handy but often overlooked freebie that comes with it is the USB-C to USB-C cable. This is absolutely essential if you plan to fast-charge the power bank fast using a PD charger or if you plan to fast-charge Android PD phones such as Pixels.

EasyAcc 20000 and EasyAcc 20000 USB-C are excellent value for money power banks and come with as many as 4 charging ports and some really unique features.

EasyAcc 20000 has a killer feature rarely seen in other power banks – pass-through charging. This allows you to charge the power bank and also charge phones through it at the same time. This is especially handy while charging via portable solar-panels. The EasyAcc 20000 has 4 regular USB charging ports and two micro-USB ports for charging the power bank.  The power bank can deliver maximum 2.4 amps per port and has a 4.8 amp combined output. This means you can either charge four phones at once at regular charging speed (1 amp or same speed as Apple 5-watt iPhone charger) or charge two phones simultaneously at 2.4 amp fast charging speed.

This is our favorite tried and tested favorite solar-charging compatible power bank. Two input ports also allows you to plug-in two charging cables from solar-chargers for double the charging speed. For charging it in just 7 hours, you can use a dual-port charger such as Anker 24-watt dual charger.

EasyAcc 20000 will charge all iPhones at twice the speed of Apple 5-watt/1-amp iPhone charger and it charges Samsung/LG/Moto/Mi Android phones at zero to 50% in 50-60 minutes (2.4 amps max).

EasyAcc 20000 will get fully charged in 12-14 hours if one micro-USB cable is used for charging. You can halve charging time to 7 hours by plugging-in two cables. Your wall chargers must be 2.4 amp/12-watt (you can use a charger such as Anker 24-watt dual charger) for fastest possible charging. Charging time using Apple iPhone 1-amp or 5-watt charger will be 24+ hours.

EasyAcc 20000 USB-C is one step up from the plain vanilla EasyAcc 20000 and features USB-C input for charging the power bank with the USB-C chargers that comes with most Android phones these days and USB-C output for charging USB-C phones. Please Note: It DOES NOT have USB-C PD which means it will NOT fast-charge latest iPhones 11/XR/8/8+ etc. or Pixels to 50% in 30 mins.

Best Looking Light & Compact 20000mah Portable Charger for iPhones, iPads and Android phones

Anker PowerCore 20100 

20000mah power bank for iPhones
PowerCore 20100 weighs just 12.6 oz (356 grams) 

 Anker PowerCore 20100 is an old favorite and five years ago it was our #1 pick but lack of new features such as USB-C and Quickcharge pushed it down over the years. Anker still sells it and it is still perhaps the best looking 20k mah power bank in the market but strictly only for those with old style USB power adapters as it gets charged via micro-USB port. It supports max 2.4 amp charging (12-watt) and will charge any iPhone or Samsung to about 50-60% in 1 hour. Also it can output 2.4 amp from both ports at once – 2.4 amp + 2.4 amp for a total of 4.8 amp. Anker PowerCore 20100 takes about 10-12 hours to charge which is inconvenient unless you need it sparsely and plan to charge it overnight.

 Anker PowerCore 20100 What We Like

  • Zero to 50% in 50-60 minutes charging for all iPhones including latest iPhone 12/11/11 Pro/XR/XS/XS Max, X, 8, 8 Plus
  • Zero to 50% in about 50-70 minutes for Android phones including Samsung phones – Galaxy S20, S10, S10+, S10e, S9, S9+, S8, S8+,S7, S7 Edge, S6, Note 9, 8, Note 5 etc.
  • 12.6 oz (360 gram) is light for a premium 20000mah power bank
  • Compact sleek build – most compact in class

Anker PowerCore 20100 What We Do not like

  • No way to charge it faster. The portable charger takes minimum 10-12 hours to charge with most Samsung/Android phone chargers (2.4 amp or above) and almost 24 hours with Apple stock iPhone 1-amp/5-watt  chargers. If you have an iPhone 5-watt/1-amp charger, you can get an inexpensive 12-watt dual charger such as Anker 24-watt dual charger to charge your iPhone twice as fast and to also charge the power bank in 10 hours at the same time.
  • No USB-C port for charging power bank or for many new phones like iPhone 12 that come with a USB-C charging cable.
