Some people (not I) carry a CO2 inflator for the field repair of the wheel. A small, lightweight thing which does not require any recharging.
For me, it is a big upright bike pump at home (it literally takes some 5-6 movements to restore the pressure, once a week). I'm not getting particularly tired when I reinflate the wheel after a tyre change, which is a rare thing to me
For long rides, I carry this with me:
Topeak Mountain TT-G Twin Turbo manual pump. 227 g or 8 oz. Good for Presta or Schrader valves, and it has a gauge. Every movement of the piston (forward or backward) delivers a huge amount of air to the inner tube. This model is limited to 4 bar (58 psi), which is enough for any of my e-bikes.
The more and more I'm riding the less and less I'm interested in
gizmoism Every single thing you need to carry makes your e-bike even heavier. Every electronic gadget is one more you need to recharge.
i don't carry a pump with me on rides. I like to live dangerously
It's your choice, haha! I only do not take tools or the pump on grocery shopping rides but these never exceed 10 miles
Otherwise... Once I set off for a simple ride to Warsaw, bike paths only. Already on the 5th mile, I got a flat
Necessary to mention, flats occur to other people (I can recollect exactly four* tyre flats in four years). In that specific situations, I gave my friendly cab driver a phone call to avoid a long Walk Of Shame

*) The only tyre flats I have had:
- Lovelec. The puncture got sealed by the tube sealant. I only needed a pump to reinflate the tyre
- Giant Trance E+ (tubeless). A piece of quartzite punctured the tyre. The sealant fixed the hole (I only needed the pump to reinflate the wheel).
- Vado SL. A pinch flat because of wrongly installed inner tube. A 1-km Walk Of Shame.
- Vado SL. A flat as described above. I took no tools with me on that ride.
I hav never had a single flat on my big Vado!
