Can I charge a picow with the LiPo Charger Plus

I have a Pimoroni Pico plus 2W with a USB-C connector. I would like to power the Pimoroni with my 3.7V LiPo battery with a 2 pin JST connector.

If I use the LiPo Charger Plus to power my battery, can I then use the LiPo Charger Plus to power the Pimoroni into its USB-C connector, basically reversing the LiPo Charger Plus to discharge from the battery to power the Pico?

No, that won’t work. The USB C connector on both devices accept external power, they don’t prodce it. It would be like connecting two light bulbs together expecting one to power the other.
