EcoFlow River 3 Plus Arrived but will only charge using AC only at 170w

Received my River 3 Plus today. Purchased on a special deal along with a 45w solar panel for an unbeatable price in my opinion.

However, it will not charge over 170w plugged into AC alone. I searched the forum here but couldn't find this specifically addressed previously.

Shouldn't this be able to charge in the 300w range on AC alone? The slider is all the way up to 650w, and if I slide it down to the minimum of 80w and apply the change, it drops to 80w. Sliding back up to the 650w and apply, it goes back to 170w and stays. I also tried 175, 200, 225, 250, etc., all to no avail. It likes that 170. I'll keep tinkering with levels in hopes it goes higher, that is if its actually capable.

Firmware states it's current, and the charge level is at 35% presently. Apologies if this was discussed and my ability to find a previous discussion on this is lacking.

Thanks for any info! I love this little guy.
