Figure 1. The Dynamo Pro 17 Rechargeable 12V DC Mobile Power Station.
Congratulations on your purchase of an Orion Dynamo Pro 17. The generous 17 amp-hour bat-
tery size provides power for more than twice as long as standard 7 amp-hour batteries before
recharging is needed. In addition to powering your astronomical instruments, the Dynamo Pro 17
also serves as a power supply for a multitude of devices. It includes a red lens flashlight for night-
vision preservation, as well as an 800,000-candlepower halogen spotlight. The built-in radio will
keep you entertained while observing and informed during emergencies. The Dynamo Pro 17 can
even start your car if its battery is drained!

1. Operation
Fully charge the Dynamo before
using it for the first time.
Powering 12-Volt Devices
The Dynamo Pro 17 will operate up to two devices that are
powered by a 12V/10A car cigarette lighter-type plug. If your
12V device does not have a cigarette lighter-type plug, then
you will need to purchase an adapter (contact Orion or your
local electronics store). The tip of the plug will receive the pos-
itive charge (tip positive) from the Dynamo Pro 17, so make
sure the device to be powered is also tip positive. If the device
is tip negative, then an adapter is needed. (Some cigarette
lighter-type plug adapters allow you to switch between tip
positive and tip negative.) If both of the 12V sockets are being
used simultaneously, the total amperage of the 12V devices
together must not exceed 10 Amps.
Switch the power switch (Figure 1) to the “ON” position and
the green “READY TO USE” power indicator LED should
shine. Slide open the door to one of the 12V/10A output jacks
and insert the device’s 12V power plug.
Powering 3/6/9-Volt Devices
The Dynamo Pro 17 has three separate output jacks that can
be used respectively to power devices requiring 3, 6, or 9 volts
and no more than 1 Amp.The jacks accept standard DC power
plugs with a 2.1mm inner diameter and 5.5mm outer diameter.
The output from these jacks is tip positive. Using more than
one of the 3/6/9V output jacks at once is not recommended
due to the 1 Amp power limit.
To use these jacks, simply turn the Dynamo Pro 17 power
switch to the “ON” position and insert the device’s plug into the
appropriate output jack.
Operating the 12V Flashlight
The 12V flashlight located on the top of the Dynamo Pro 17
is a medium-power light that can be used to provide illumina-
tion to a small area. It has a red lens to preserve night vision
under dark skies. The flashlight can also be removed from the
body of the Dynamo Pro 17. Simply grab hold of the front of
the flashlight, and pull it out.You will notice that the flashlight is
tethered by a 10-foot long cable. For your convenience, there
is a cable-winder built into the rear of the flashlight. To expose
the cable-winder, fold back the rear cover of the flashlight.
You will also notice that there is a magnet on the rear cover;
this can be used to attach the flashlight to a metal surface for
“hands-free” applications.
To operate the flashlight, the Dynamo Pro 17 power switch
must be in the “ON” position. Press the flashlight button (Figure
1) once to produce a constant light. Pressing the button a sec-
ond time will cause the flashlight to flash on and off steadily.
Pressing the button a third time will turn the flashlight off.
Operating the Spotlight
The spotlight is an 800,000 candlepower halogen light.
Although it has many useful applications, the use of such a
powerful light at astronomical gatherings is not advised.
To operate the spotlight, the Dynamo Pro 17 power switch
must be in the “ON” position. Flip the spotlight switch (Figure
1) to the “ON” position. The spotlight can be rotated about its
hinge (Figure 1) for easy positioning of its beam. Simply take
hold of the spotlight and move it to the position you want.
Operating the Radio
To use the radio, the power switch must be in the “ON” posi-
tion. The radio switch (Figure 1) allows you to select between
FM radio, AM radio, or the internal siren. The internal siren is
for emergency situations.
To turn the radio on, rotate the volume dial clockwise until it
clicks on. The tuning dial allows you to adjust the frequency
to the desired radio station signal. To turn the radio off, rotate
the volume dial counterclockwise until it clicks into the off posi-
tion.
2. Recharging the Dynamo
Pro 17
If the yellow “NEEDS CHARGING” LED indicator light is shin-
ing, the battery power is low and requires recharging. The
battery can be recharged from an AC outlet or from a DC
source, such as a car cigarette lighter.
Recharging the Dynamo Pro 17 with AC Current
Recharging the Dynamo Pro 17 with an AC current outlet
requires the included AC adapter. Do not use substitute AC
adapters. The AC adapter is stored in the compartment above
the car battery clips.
Press the power switch into the “CHA”, or charge position.
Then plug the small end of the AC adapter into the charge
input jack located at the rear of the Dynamo Pro 17, and plug
the other end of the adapter into a 110V AC wall outlet. The
red “CHARGING” LED light should come on indicating that the
battery is charging.
Charging should take around 14-20 hours, depending upon
how drained the battery is. The green “FULLY CHARGED”
LED light should shine when the battery is fully charged.
Unplug the adapter from the Dynamo Pro 17, and the “READY
TO USE” LED should shine again once the power switch is in
the “ON” position.
Recharging the Dynamo Pro 17 with DC Current
Recharging the Dynamo Pro 17 with DC current should be
done with the cigarette lighter outlet in an automobile. The
car’s engine must be operating during charging. The DC
recharging adapter is stored in the compartment above the
car battery clips.
Press the power switch into the “CHA” position. Plug the small
end of the DC adapter into the charge input jack located at
the rear of the Dynamo Pro 17. Make certain the car engine
is running, then plug the other end of the DC adapter into the
cigarette lighter in the car. The red “CHARGING” LED light will
come on indicating the battery is charging.
Charging should take about 5-8 hours. The green “FULLY
CHARGED” LED light should shine when the battery is fully

3
charged. Unplug the adapter from the Dynamo Pro 17, and
the “READY TO USE” LED should shine again once the power
switch is in the “ON” position.
3. Using the Dynamo Pro 17
to Start a Vehicle
The Dynamo Pro 17 can be used to help start a vehicle that
has a drained battery. It may not have sufficient power to
charge a severely drained, or extremely large (greater than
4000cc engine), car battery.
To use the Dynamo Pro 17 to help start a vehicle:
1) Put the power switch in the “ON” position.
2) Connect the red clip (+) on the Dynamo Pro 17 to the
positive pole (+) on the car battery
3) Connect the black clip (-) on the Dynamo Pro 17 to the
negative pole (+) on the car battery
4) Wait a few seconds, then attempt to start the car.
5) Remove the Dynamo Pro 17 clips from the car battery.
4. Storage and Maintenance
To optimize the lifetime of the Dynamo Pro 17, several steps
should be taken for its proper storage and maintenance. Make
certain the Dynamo Pro 17 power switch is in the “OFF” posi-
tion before putting it in storage.Keep the Dynamo Pro 17 stored
a dry, cool area when not in use. Fully charge the Dynamo Pro
17 before putting it into storage. If you are going to store the
Dynamo Pro 17 for long periods of time, you should occasion-
ally recharge it (about every three months). Failure to do so
will void your warranty.
Resetting the Circuit Breaker
If the power indicator LED light does not come on when you
turn the power switch, the circuit breaker (Figure 1) will need
to be reset. Turn the power switch to the “OFF” position and
press the circuit breaker button to reset it. Keep in mind that
if you are drawing more than 10 Amps through the 12V/10A
adapters you will always cause the circuit breaker to break.
Replacing the 2 Amp Fuse
If the fuse for the 3V/6V/9V power jacks should blow, it can be
replaced with a new 2 Amp (5mm x 20mm long, 250 VAC, fast
acting) fuse. Turn the power switch to the “OFF” position, then
turn the fuse securing knob (Figure 1) in the indicated direc-
tion to free the old fuse. Replace it with the new fuse. Replace
the fuse securing knob.
Replacing the Flashlight Bulb
Should the flashlight bulb break or burn out, it can be replaced
with a 12V, 0.5A Krypton bulb, available at most hardware
stores. Make certain the power switch is in the “OFF” position
before replacing the bulb.
To replace the bulb, unthread the flashlight head by turning it
counterclockwise. Replace the old bulb with the new bulb and
thread the flashlight head back onto the flashlight.
Replacing the Spotlight Bulb
Should the spotlight bulb break or burn out, it can be replaced
with an H3 12V 55W halogen bulb, available at most hardware
stores. Make certain the power switch is in the “OFF” position
before replacing the bulb.
To replace the bulb, unthread the spotlight head by turning it
counterclockwise. Make certain the old bulb and the reflector
have had plenty of time to cool down before you touch either
one. Separate the reflector from the bulb by removing the clip
shown in Figure 2. The entire bulb assembly, including its cord
(color white), is removed by detaching the end of the cord
from the connecting clip within the spotlight housing. Replace
the bulb assembly, and reassemble the spotlight.
