I have this. It seems way overpriced but it came included with a dock/chairs/cooler etc. I like the features if you can get them in a much better deal It will go right up to the PSI you want and then stop Plus when you're done you can run it in reverse to withdraw the air https://www.boteboard.com/collections/pumps/products/aeropump-auto-electric-pump-ii#
I have this one: https://www.amazon.com/dp/B08L4SGS2X?psc=1&ref=ppx_yo2ov_dt_b_product_details No wonder OP is confused, there are too many options! And Amazon needs to give us a kick back for all of the referrals today
Have been using this WM pump https://www.westmarine.com/west-marine-12v-premium-electric-inflator-pump-15-cfm-19941376.html for years. Cut off the alligator clips and hard wired into the Trunk. Works great for the Dingy, SUP and all the floats.
