The ones with inbuilt batteries are meant for emergencies/very rare use. And once the battery dies, they are useless.
Get one with a 12V cigarette port input from a reputed brand, and power it from bike/car directly with engine running. My previous inflator from Slime lasted from 2012 to 2023 with occasional usage.
One thing I don't like about the current models is they have a screw on type nozzle to conenct to the valve instead of quick release ones. Some air
will leak out when you're trying to disconnect the inflator, and quite frankly it's a bit of a unnecessary hassle. Example quick connector:
