The battery pack is only suitable for charging basic, lower power draw devices given that the ports are limited to 12W each (24W total) using the standard 5V/2.4A USB-A mode.
This could be even more problematic with USB-A to USB-C cables which might limit charging to 1.5A / 7.5W or less (as low as the default 5V/500mA or 2.5W)
The battery pack is recharged using micro-USB limited to 10W
These rates are slow and limiting, but also maximize the efficiency of both charging and discharging. You can expect this charger to easily take 6-8 hours to recharge from empty.
However, the two big pros I'd note:
The digital display should give a very clear indication of charge state relative to the basic 4-5 LED indicator bar typical of basic models. This could further allow you to optimally manage the battery pack health by maintaining the state of charge within optimal ranges (keeping above 20% but limiting charge to 80%, for example).
The actual capacity of the device is likely very close (if not spot on) to the claimed 20,000 mAh rating.
This is a big distinction from typical knock-off brands that make ridiculous capacity claims that border on criminal.
Good luck!
