GPUTEK Mini Bike Tire Air Pump: Fast Inflate Portable Small Bicycle Electric Pump for Presta and Schrader Valves, 120 Psi High Pressure Pump with Digital Gauge for Road Bike, Mountain Bike, E-Bike

https://a.co/d/0gkhIw9m I have that one. It's really small and fits in my little bag on my scooter.

I agree, I would never trust an electric pump as my only source. I have a mini hand pump on all of my bikes. I have one electric pump that I swap around from bike to bike since it's more convenient to use.
