What portable reserve energy can do

  • Bridge a gap: deliver enough energy to reach a working charger when plans change.
  • Travel with you: portable energy does not depend on fixed infrastructure being where you need it.
  • Restore momentum: a modest amount of energy can turn a stranded moment into a planned stop.

What it cannot do

  • Replace a full recharge: portable systems carry far less energy than a fixed charging station or a full battery.
  • Fit every vehicle without checks: a connection only works when the vehicle and the system are compatible.
  • Substitute good planning: reserve energy is a backup, not a reason to skip charging stops.
  • Deliver road-trip pace: moving energy into a vehicle battery is slower than drawing it from the grid.

What determines the outcome

Three factors decide how far stored energy takes you: how much energy is delivered, how efficient the vehicle is, and how far away the next working charger is. At roughly 2.5–4 miles per kWh, even a few kilowatt-hours can represent meaningful miles — but they are bridge miles, not destination miles.

RESERVE is engineered around exactly this role: a planned, portable reserve for the gap between where you are and the next working charger.
