USB-C recharge from empty

On occasion I’ve depleted the battery on my Blade 14 (2022) and I’m finding that USB-C can’t bring the device back: I have to use the large power-brick to give the device a little charge before the USB-C starts to work again.  When the device is not depleted, the same USB-C charger works; the charger is an Anker USB C 736 Charger (Nano II 100W) with a dedicated port for laptops and no other cables or devices plugged in at the same time.  Is this a known limitation of using the USB-C ports for charging on the Razer Blade:  does USB-PD require a little bit of power to function at all? I ask because I would like to travel with my Blade 14 without the large power-brick but I don’t want to be left on the lurch if I accidentally deplete the battery.
