Determine Battery Capacity
Battery type and battery size strongly affect the performance. Therefore,
you need to identify the type of loads your inverter will be powering and
how much you will be using them between charges. Once you know how
much power you will be using, you can determine how much battery
capacity you need. Technaxx recommends that you purchase as much
battery capacity as possible.
CAUTION: Risk of inverter damage.
⚫ The inverter must only be connected to a battery that has a nominal
output of 12V. ⚫Not operate if connected to a 6/24V battery
Voltage converter installation
Install the power inverter with suitable screws (not included) or by car
adapter cable:
⚫ in sturdy and even locations,
⚫ on clean, dry and non-flammable surfaces,
⚫ in well ventilated areas.
Please be sure not to cover the vent.
Connecting the inverter
This unit contains a pair of DC input terminals to connect a 3ft. car adapter
cable or option 3ft. battery cable with alligator connectors that directly
attaches to a battery's DC terminals.
The order of steps in the following procedure minimizes the danger of
sparking near the battery bank.
Option1
⚫ Prepare all cable set ends with ring terminals at the battery ends
⚫ Select the OFF position on the inverter
⚫ Remove the red positive(+) screw connector cap
⚫ Slide the red positive(+) cable lead onto the red positive(+) screw
connector stud. Tighten the screw connector cap securely
⚫ Remove the Black negative(-) screw connector cap
⚫ Slide the Black negative(-) cable lead onto the Black negative(-) screw
connector stud. Tighten the screw connector cap securely
⚫ Securely connect the red positive (+) cable lead to the positive (+)
terminal of the battery or power source
⚫ Securely connect the black negative (-) cable lead to the negative (-)

terminal of the battery or power source
Option 2
⚫ Plug the cigarette lighter into your 12V sources
Note: Sparking is normal for first connection.
Operation
Before using the power inverter determine your equipment’s total
watts!
⚫ Do not connect more watt than the Output Power (maximum continuous
watt) of the device (➔ see technical specifications).
⚫ Determine Total Wattage Required, Watt ratings are usually listed in
equipment manuals or on nameplates. If your equipment is rated in Amp,
multiply that number times AC utility voltage to determine watts.
(mathematic example: a drill requires 1A →1A x 230Volt = 230Watt. →
No problem to use the drill.)
⚫ Remember the vehicle‘s battery will be discharged when the vehicle is
not running.
⚫ To Determine DC Battery Amps Required, divide the total wattage
required (from above) by the nominal battery voltage to determine the DC
amps required. 230Watt / 12V = 19.17A DC
⚫ To Estimate Battery Amp-Hours Required Multiply the DC amps
required (from above) by the number of hours you estimate you will
operate your equipment exclusively from battery power before you have
to recharge your batteries with utility- or generator-supplied AC power.
Compensate for inefficiency by multiplying this number by 1.2. This will
give you a rough estimate of how many amp-hours of battery power (from
one or several batteries) you should connect to your Inverter/Charger.
28.75A DC x 0.5h runtime x 1.2 inefficiency rating = 17.25 amp-hours
⚫ To Estimate Battery Recharge Required, Given Your Application You
must allow your batteries to recharge long enough to replace the charge
lost during inverter operation or else you will eventually run down your
batteries. To estimate the minimum amount of time you need to recharge
your batteries given your application, divide your required battery amp-
hours (from above) by your Inverter/Charger’s rated charging amps
(depending on the ON/OFF settings).
17.25 amp-hours / 40A inverter/charger rating = 0.43h recharge
Operation
Turn ON the inverter: Press ON/OFF Button on the panel. The GREEN
LED Indicator will light up verifying the inverter is receiving power
Turn OFF the inverter: Press ON/OFF Button on the panel.

When you have confirmed that the appliance to be operated is turned off,
plug an appliance cord into a 230V AC outlets on the front panel of the
inverter
Note: If you are going to operate several loads from the inverter, turn them
on separately after you have turned the inverter on. This will ensure that
the inverter does not have to deliver the starting current for all the loads at
once.
Temperature Protection
The Inverter is equipped with a cooling fan.
TROUBLESHOOTING
Possible Cause
Remedy
An overload/over-
temperature
shutdown has occurred
Use an AC-powered device that a power
rating of less than rated power. Allow the
inverter to cool down, or
try to reduce the ambient temperature and
try again
Do not cover the inverter’s ventilation
openings.
High starting surge has
caused an overload
shutdown.
Use an AC-powered device that has a
surge power rating
less than the surge power rating of the
Inverter
Vehicle’s ignition
switch is turned
Off thus the DC
accessory socket is
also off
Turn the vehicle’s ignition switch to ON.
Consult your
Vehicle’s manual for instruction
Poor contact with DC
accessory
Socket
Adjust the inverter’s DC plug to ensure a
snug fit. If needed,
Clean the DC accessory socket
Vehicle battery is
discharged
Recharge the vehicle battery
Vehicle fuse blown due
to heavy load on the
accessory socket
Replace the blown fuse. Consult your
vehicle’s manual for fuse location, fuse
type, and instructions.
USB connector is not
inserted properly into
the USB port
Ensure that USB cable’s connectors are
properly fitted into the USB ports of either
device.
Warnings & Caution

⚫ Use of the device in life support applications where failure of the device can
reasonably be expected to cause the failure of the life support equipment or to
significantly affect its safety or effectiveness is not recommended. ⚫ Do not use the
device in the presence of a flammable anesthetic mixture with air, oxygen or nitrous
oxide, and also not near flammable materials, fumes or gases. ⚫ Since the device
requires adequate ventilation during operation, do not block fan or cooling vents and
do not cover the device. Do not operate near car heating vents or in direct sunlight. ⚫
Keep the device dry at all times and disconnect when not in use. ⚫ Turn OFF
connected equipment before (!) starting your engine. DO NOT plug a surge protector,
line conditioner or UPS system into the device. If you attach AC extension cords, use
the heaviest practical gauge. ⚫ Before connecting a battery charger or adapter, check
its manual to make sure that the technical specifications of the device fall within the
recommendations of the external battery charger or adapter.
