Indeed.. I don't much care for solutions like the i3 rex. That's why I propose hauling around the charger only when needed. Its not so much stopping every 2-4 hours that's the problem. If it was a 3-5 minute stop, it would be fine, but its a 20-40 minute stop (assuming no contention for chargers). I've taken many 900+ mile (each direction) road trips in my car. Charging generally ads about 25% to the overall elapsed time. The chargers (at least in the I95 corridor in the USA) are often not equipped with 24hr restrooms.
