MetAir Ranger Series Battery Portable Power

July 17, 2012

QuantumSphere, Inc.'s MetAir Ranger series for on-demand back-up power in off-grid and emergency applications.  While already offering the highest energy density of any commercially available primary battery at the lowest cost per kilowatt hour, QSI’s MetAir Ranger portable power system has received independent validation that it surpasses the industry’s 72-hour emergency preparedness benchmark. The system achieved an unprecedented 108 hours – four and a half days – of instantly accessible emergency power. 

The MetAir Ranger Series portable power product is ideal for first responders, military, home, school, and business emergency preparedness. 

MetAir Ranger Features

  • High Energy Density
  • Low Cost Per Kilowatt Hour
  • Long Life (up to 10 Years Sealed)
  • Portable, Lightweight, Reliable, Off-Grid Emergency Power Source
  • Modular Design, Easily Scalable
  • Replaceable Multi-Cell Power Stack -Disposable with Household Waste
  • Non-Toxic, Safe, Non-Combustible
  • No Liquid Fuels, No Added Mercury, Cadmium, Lead or Lithium
  • Zinc-Air Batteries are D.O.T Approved for Transport by Air, Land and Sea
  • Wide Operating Temperature Range

The MetAir Ranger, a 3.2 kilowatt hour battery system weighing less than 25 pounds, yields energy densities of 352 Wh / Kg and costs per kilowatt hour of less than $200. While one MetAir Ranger system is about the size of a single deep cycle lead acid battery, it is roughly half the weight and has 11 times the equivalent energy per kilogram. It is also designed to accept easily replaceable power cartridges once the initial multi-cell stack is "air" activated and used up. The MetAir Ranger Series is essentially a "plug and play" box of portable energy and requires no external energy sources to stay charged.  The MetAir Ranger has an optional 150 watt 110 volt AC inverter with two outlets and a USB charging port.  The MetAir Ranger contains no hazardous materials or combustible fuels and, unlike large format Lithium batteries, is approved for transport by the Department of Transportation as non-hazardous material.

In comparison to the commonly available battery types used today, such as Lithium-ion, Nickel metal hydride and Lead acid, QSI's technology is based on a safe and proven zinc-air battery chemistry that is cost effective to manufacture and easy to use.  Zinc-air batteries are electro-chemical batteries powered by oxidizing zinc metal powder (a non-combustible, non-toxic and abundant domestic material) with oxygen from the air to generate an electrical current. In addition, Zinc-air batteries have very high energy densities and an unprecedented shelf life of up to 10 years before initial use. Sizes range from very small button cells for hearing aids, mid-size for remote portable power applications, to very large systems used for electric vehicle propulsion.

Main Applications

  • Portable, Off-Grid, Back-Up Power
  • Emergency Communications Equipment for First Responders, Military
  • Home, School, Business Emergency Preparedness / Back-Up Power
  • Outdoor Sports and Recreation
  • Off-Grid / Back-Up Power for Portable, Consumer Electronic Devices

The need for reliable, off-grid, back-up power solutions is clear and growing.  According to FEMA, major disaster declarations in the U.S. have grown 400% since 1950.  In 2011, statistics show that there were 3,071 reported power outages across the U.S., affecting 41.8 million people. The chief causes of these outages were commercial system overloads and natural disasters.  In a recent report on U.S. electricity infrastructure, ASCE President Andrew W. Herrmann warns that power interruptions could cost companies thousands of dollars per day.
