We have onboard air so no need for self Inflating. Been looking around and getting a headache with all the choices. They all say they’re the best so what’s the best value? Been out of the camping scene for about 30 years.
Not all air pumps are equal. Most likely your OBA is a high pressure, low volume. Usually for an air mattress, you want a low pressure, high volume style pump. If you’re in the DeWalt 20v ecosystem, they have a battery air inflator that does both. That’s what I use to inflate my REI air mattress. It’s a “queen” but I call it a camping queen. Plenty of room for two and I’ve enjoyed it over the years.
