in writing to me about
portable electric power
pack supply sources. I
used and researched several of the various models
available. They are exJim Dulley
cellent for emergencies
(such as power outages during storms) and
for recreational and home use. If you need to
run a standard saw, trimmer, etc., out in your
yard or in the woods, these power packs can
handle this for you. I use one for backup
power for my pellet/corn stove in emergency
power outages.
All of the power packs use 12-volt batteries. They are all sealed lead acid batteries
that require no maintenance and will not
leak. Clore Automotive uses an absorbent
glass matt type of battery that can be used in
any position. Most standard batteries, even
sealed ones which do not leak when they are
knocked over, generally should be used in an
upright position.

There are
many 12-volt DC (direct current) appliances
available at most camping and outdoor equipment shops. You plug these into the 12-volt
socket on the power pack. The socket is
usually a basic car cigarette lighter socket. If
your power pack needs recharging, you can
plug it into your car cigarette lighter as you
drive and it will recharge in several hours.
Standard household items, TV’s, radios,
clocks, lights, etc., operate on 115-volt AC
(alternating current). In order to convert the 12-volt

advantage of a separate inverter is that you

your car. Pay attention to the maximum
wattage output of the inverter so you do not
exceed it in use to it may overheat.
All of the units I have listed on pages
one and two are of excellent quality. The
models that are about 20 amp-hours and less
provide plenty of emergency power and are
ideal for portability (attractive, easy-to-carry
cases). The heavier, higher capacity models
are often used with stationary solar or wind
generation systems, but they will provide a
lot of electricity for an extended emergency
The prices vary from about $30 to more
than $150 depending upon the maximum
battery and inverter output. Vector sells
remanufactured models online for the lowest cost, but they do not have built-in inverters. The Black & Decker Electromate 400
is one of the nicest models with
convenient controls and handle
for carrying. Its suggested retail
price is $99.

En-R-Pak by National Solar Technology
(shown with optional solar panel)
The En-R-Pak
200 will control and
store power from a
car battery, household power, solar
panels, and a wind or
water turbine. It uses
the stored energy to
output 115 volts
(pure sine wave A/C)
and 12 volts DC. A
230 volt (50 Hertz or
60 Hertz) unit is available for international use.
No assembly is required. All of the electronics and gel cell batteries
are built into one unit. There are no wires to connect, no part drawings to
decipher and no set-up headaches. Your unit arrives charged and ready
to use. All you do is point the solar panel south,
plug the prewired cable connections into the power
center and you will be producing your own electrical power. Expansion Chassis (pictured on the left)
is an optional portable unit that has another built-in
battery and control circuits for an additional 100
amp hours of storage. A charge cable is included.

Jazz Inverter by Xantrex
“Freedom Jazz Inverter” - Provides 120 volt AC current from 12 volt DC current wherever it is needed. Portable power
and easy to install advanced series power. Capacities range from 50 to 2,500 watts to power almost any appliance.
High efficiency, compact design, High/Low voltage protection circuitry protects the inverter whenever input voltage
exceeds 15 volts DC or less than 10.5 volts DC. Thermal Cutoff automatically shuts inverter down if internal temperature
exceeds standard design parameters for safe operation
When sizing your inverter, simply calculate the highest total wattage needed at any one time and choose the closest
inverter with a higher output. For practical application, most people operate only one or two major appliances at a time. Start
up watts should be considered where appropriate.
Preparing for Emergencies
There are many items you should have in your automobile and
things you should do to be prepared for an emergency.
• Even if you are at home when a disaster strikes, and your home
is well stocked, you may still need the supplies in your car. Your
house may not be safe to enter, or may catch fire after a natural
disaster such as an earthquake.
• Your car will be one of the most important resources after a
disaster strikes. Keep it mechanically sound and pay close attention to the exhaust system. A leaking exhaust system could
• Always make sure you keep your gas tank full. Fill it when it is
half empty. You will thank yourself the first time you are stuck
in a traffic jam during bad weather.
• Think of your car’s trunk as an extra large supply cabinet. Keep
your supplies in the trunk along with other important items such
as tools, jumper cables and a spare tire.
• Keep the car mechanically sound and ready to use.
• Keep supplies in the car for use in an emergency.
• Replace your battery every five years. In an emergency, your car
battery needs to run the radio and heater for extended periods.
Have a mechanic check the following items on your vehicle
to keep it ready for an emergency: battery, antifreeze, wipers and
windshield washer fluid, ignition system, thermostat, lights and
flashing hazard, exhaust system, heater, brakes, defroster, tire
pressures and treads
To prevent car batteries from becoming a problem, perform
regular routine maintenance on the battery. Maintaining the correct electrolyte levels, tightening loose hold-down clamps and terminals are maintenance batteries require. Additionally, removing
corrosion and checking the alternator belt tension are also preventative maintenance steps required for a battery.
The frequency you perform these steps depends on your climate and battery type, but you should perform at least once before
cold weather starts and once a month during hot weather.
If the electrolyte levels are low in non-sealed batteries, add
distilled water to the level indicated by the battery manufacturer
or to 1/8” below the bottom of the filler tube. Try not to overfill,
especially in hot climates.
