I tested the Dell XPS13 9380, the new thinkpad x390, and the razer stealth 13 - all based on almost identical chipsets. None of them had the same issue, although Dell did ship a bad TB3 driver which needed to be manually fixed. I have other USB-C devices, including phone, that charge just fine on any charger.
