electric can be bulky if you have limited space. I have a ryobi tire pump that is fairly compact. It works very well. and the battery seems to hold its charge. When going on more than a day trip it gets left a home and I use a bicycle pump. I can pump up the tire in a reasonable amount of time if I have to and not have the bulk of a electric pump. The other option would be a co2 inflator. You would need multiple co2 cartridges per tire to fully inflate it.
