Zendure SuperTank: Power Your Phone For A Week, Recharge In One Hour
Just backed this one for $89 USD, spec looks awesome with dual USB-C port capable of 100W input/output, 1 QC3.0 USB port. Capacity is maxed out at 27k/99.9Wh. Functionality wise, USB hub, passthrough charging, low power mode, battery % display, you name it
Only downside is the weight and size, gonna be literally a tank (at least 600g I suspect)!
I think you mean figuratively. A tank literally weighs ~50-70 tonnes.
