18-watt for Samsung/Android devices – 0 to 50% in 30-40 minutes
The Xiaomi Redmi 20000 has two USB charging connections and two power bank charging connectors.
The Xiaomi Redmi 20000 is without a doubt the greatest power bank bargain in the 20000mAh category. It has good quality, can be charged by USB-C and micro-USB, and is reasonably priced. Xiaomi Redmi 20000 supports up to 12 watt charging for the newest iPhone 13/12 phones and 18 watt fast charging for the Samsung S/Note/A series, with a total of two charge ports (2 USB) and two charging ports for the power bank (USB-C or micro-USB).

EasyAcc USB-C 20000
EasyAcc 20000 USB-C features four charging ports and may be charged by USB-C or micro-USB.
We suggest the superb ZMI Powerpack Ambi 10000 UPS PD Passthrough portable charger if you want an ultra-light 10000 mah USB-C PD pass-through power bank.
EasyAcc 20000 USB-C power banks provide great value for money, with up to four charging connections and some really unusual features.
The EasyAcc 20000 features a standout feature that you won’t find in many other power banks: pass-through charging. This enables you to charge the power bank while simultaneously charging your phone. This is particularly useful when using portable solar panels to charge. For charging the power bank, the EasyAcc 20000 includes four normal USB charging connections and two micro-USB charging ports. The power bank has a total capacity of 4.8 amps and can provide up to 2.4 amps per port. This means you can charge four phones at the same time at normal charging speed (1 amp, or the same pace as an Apple 5-watt iPhone charger) or two phones at 2.4 amp rapid charging speed.
This is our best solar-charging compatible power bank, which has been tried and proven. Two input ports also enable you to connect two solar-charger charging cables for twice the charging speed. You may use a multi-port charger like the Anker 24-watt dual charger to charge it in only 7 hours.
EasyAcc 20000 charges all iPhones twice as fast as Apple’s 5-watt/1-amp iPhone charger, and Samsung/LG/Moto/Mi Android phones from zero to 50% in 50-60 minutes (2.4 amps max).
If just one micro-USB cable is used to charge the EasyAcc 20000 USB-C, it will be completely charged in 12-14 hours. By connecting two connections, you can cut the charging time in half, to only 7 hours. For the quickest charging, your wall chargers must be 2.4 amp/12 watt (you may use a charger like the Anker 24-watt twin charger). It will take 24+ hours to charge an Apple iPhone using a 1-amp or 5-watt charger.
is a step up from the EasyAcc 20000 and has USB-C input for charging the power bank with the USB-C chargers that come standard with most Android phones nowadays, as well as USB-C output for charging USB-C phones. Please note that it lacks USB-C PD, which means it will not be able to charge the newest iPhones 12, 11, XR/8/8+, or Pixels to 50% in 30 minutes.
Because it supports Quickcharge 3.0, the EasyAcc 20000 USB-C will fast-charge all Samsung/LG/Moto/Mi phones to 50% in 30 minutes via its green Quickcharge 3.0 USB connector.
The EasyAcc 20000 USB-C is equipped with four charging ports: one Quickcharge USB port, two normal USB ports, and one USB-C port. It also includes two USB-C input connectors as well as a micro-USB charging port. Use a multi-port charger like the Anker 24-watt dual charger to completely charge the power bank in about 6 hours.
By connecting in two cables (USB-C and micro-USB – both supplied with the charger), you can completely charge the EasyAcc 20000 USB-C in 5 hours. It will take 12+ hours to charge with only one cable. For micro-USB cables, your power adapters must be 2 amp/10 watt, and for USB-C cables, they must be 3 amp/15 watt (We recommend Anker 24-watt dual charger for 6 hour charging). The Apple iPhone 5-watt charger will take 24+ hours to charge.
