Unfortunately, mophie is very scant on details, so we went hunting using its EAN number
3.7V/20A/20,000mAh roughly equates to 13,000mAh at 5V.
Cypress CCG2 chipset/controller PD 2.0 standard smart circuitry
USB-C port for both charging (5V/3.4A) – 17W maximum for 500 recharge cycles
The same provides USB-PD output 5/9/112/15/20V to a maximum of 1.5A (30W)
1 x USB-A port 5V/2.4A and 1 x USB-A port 5V/1A (or maximum combined 3A)
Priority charging support (delivers the full output to one device while charging)
4 LEDs for 25% increments
USB-A to USB-C short cable
775 x 159 x 232mm x 435g with impact isolation
To put this in layman’s terms, it can recharge the battery
at up to 17W. While you can use higher USB-C PD wattage chargers, it will not
speed up the charge.
It provides up to 30W of power (similar to Qualcomm Quick
Charge 4.0 specifications) and has a 5V capacity of 13,000mAh.
That means (excluding loss of efficiency) about three charges
of an iPhone XS Max or Samsung Galaxy Note9 (4000mAh). It is suitable for
tablets (<2 charges) but definitely not for higher drain products
like a MacBook or similar (requiring 60W or more). Note: some reviews state it
will charge a MacBook but consider these ‘paid’ or rubbish reviews.
If you are shopping for a power bank, the two things that
count are wattage output and the mAh delivery at 5V – not the mAH capacity of
the 3.7V battery.
Tested charge times
Using a 5V/2A standard charger – between 15-20
5V/3A USB charger of USB-C 15W – 8 to 10 hours
Car utility socket 5V/3A (as above)
JB Hi-Fi, Office works and other major retailers.
GadgetGuy’s take – mophie powerstation XXL – good price but not 20,000mAh performance
This is not a negative because few power bank makers declare the real 5V mAh capacity – all that counts. mophie should learn that it needs to have full specifications instead of us hunting for them.
If you have a smartphone, iPad or Android tablet, this is a perfect top up. It’s safe, won’t overcharge, is well made and from a good company.
Price is on par with other 30W, 5V/13,000mAh capacity power banks – you will pay much more for a 60W USB-PD 2.0/3.0 power bank.
But we must down rate is as it is advertised as a 20,000mAh and not clearly identified as a 30W smartphone/tablet only device.

Good brand, well made
Only provides 5V/13000mAh less power efficiency loss
