EV Charging

Mobi EV Charger™ can be quickly deployed to meet the rapidly changing EV market and requires no fixed infrastructure. A mobile alternative to the infrastructure-heavy, stationary L2 chargers, Mobi EV Chargers are battery-powered, providing powerful charging without the need for complex infrastructure. Setup is simple and can be done without permitting or construction, allowing for immediate deployment.

Applications include:

  • workplace EV charging in leased parking lots
  • fleet servicing in dispersed locations
  • revive dead EVs, before charging can occur.

Mobile Power

Mobi Gen™ offers clean and quiet on-site power for a variety of off-grid power needs. It supplies uninterruptible power to facilities or remote sites that require a guaranteed source of power. Mobi Gens can be used to supplement, or fully replace traditional diesel-fueled generators.

Applications include:

  • emergency situations – provide critical power wherever, whenever needed
  • movie sets, food trucks, outdoor festivals – enhance customer experience
  • underground tunnel work – improve worker health & safety
  • can also revive dead EVs.


FreeWire's purpose-built mobile power solutions include:

  • Lower energy costs: take advantage of off-peak electricity rates
  • Maximum efficiency: load balancing to avoid demand charges
  • Quality power: pure sine wave power delivery, resulting in longer lifespans for even the most sensitive devices
  • Easy setup: plug-&-play, multiple connections including the standard EVSE
  • Truly mobile solution: products can be deployed anywhere, including several models with a drive-system and a joystick that allow for exact placement
  • Low-maintenance: intelligent design requires minimal maintenance, lowering the cost of ownership
  • No stranded assets: no need for expensive infrastructure upgrades, mobile charging goes with you
  • High utilization: mobile chargers can be relocated anywhere to serve a distributed fleet, not the other way around
  • Intelligent EV charging: cloud-connected capabilities allow fleet managers to gain complete visibility into energy usage and utilization of their charging network
  • Clean & quiet power: when noise and pollution aren’t part of the plan for indoor, outdoor, and underground uses
