The size and form factor of this charger are good. It's nice to have a screen to analyse charging speeds. Gives real time voltage, amperage and a percentage. One thing I've noticed is the display flickers when charging a device. Annoying - Makes me question the longevity of the charger. But, for now it seems to be holding up okay. Suffered a small drop off a countertop and does not appear damaged. On the plus, it has apple. USB-C, Micro USB and regular USB ports. The 20,000mAh is not fully useable, more like 15,000mAh.

The pd/qc works fine, phone charges at up to 14w at 9v. I haven't tried it with anything more demanding in power It only supports up to 12v so won't charge my 20v laptop. For capacity it is rated at 76 wh, So far I averaged 69 wh out over 3 cycles and 100wh in to fully charge it over 4 cycles. So I think it is performing within reason compared to its rating. Charging efficiency isn't the greatest but a 70% round trip is as I expect from these types of devices.
