I'm IGG order #58 and this charger from iClever works with my unit. https://smile.amazon.com/gp/aw/d/B07194RXTS.

In fact, while the stock charger wouldn't work via PD passthrough with https://smile.amazon.com/gp/aw/d/B0773H6KSZ to charge my Win2, the iClever one does.

Edit: While it appears to work, it won't consistently charge and has caused the issue where I have to pull the battery to get it work. NOT RECOMMENDED.
