I added the 18V Ryobi Inflater/Deflater to my collection. An end of season Tool-Only $23 Home Depot close out.
My Ryobi Driver/Drill, Impact Driver, Hand Vac and Inflater/Deflater travel with us and they all use the same 18V Lithium batteries and I have a spare charger for them that also travels along.
For economy tools Ryobi has served me well as my reliable go-to brand for years.
