Koolatron 12V Battery Saver Turns Off Coolers, Inverters, Etc. So Vehicle Starts

by Barbara 26. January 2012 08:01

Question about using the Koolatron Kargo Kooler 12V Thermoelectric Cooler 33 Qt while my car is parked.

Q: "I am concerned about leaving the Koolatron cooler plugged in while I go into the store to shop. I want the cooler to be pre-cooled. We live in Arizona. What can I do to make sure my battery does not get too low to start the car? Thanks. Susan."

Answer: We suggest that you add a Koolatron 12V Battery Saver for Vehicles, F70110.

The battery saver can mean the difference between being stuck miles from nowhere!  To use, first plug your 12V cooler, inverter, etc. into the battery saver. Then turn on your car or truck engine and plug in the Battery Saver to the 12V outlet/cigarette lighter accessory outlet.  When you turn off the enginer, the 12V appliances or inverter will operate only until the Koolatron 12V Battery Saver F70110 senses that your vehicle voltage is below 11 volts. The battery saver then shuts off the current to all accessories plugged in, preventing further drainage. The Battery Saver reconnects automatically when you start your vehicle so your appliance or thermoelectric cooler is again operational. You'll never have to worry about your car starting again with the 12 V Battery Saver. Use with all Koolatron coolers so your car will start if you forget to disconnect the 12V plug.

  • Works with any vehicle with a cigarette lighter
  • Senses when vehicle voltage drops below 11 volts
  • Reconnects automatically
  • Model F70110
  • 1 Year warranty by Koolatron 

Thanks for your question.

Sincerely, Barbara

Top Emergency Items for Emergency Preparedness for Survival

by Barbara 6. February 2011 07:18

Question Submitted to Ask Barbara Contest: "What are the top items you recommend for an emergency kit to keep at home?" Jacqueline

Answer: As I noted in my response to Jacqueline, giving an accurate list is difficult without more specifics. For example, does she live in a house or an apartment? Is it a cold or a hot location? Is it rural or city? Is she on well water or city water? (Some rural residents have propane or gasoline powered generators so that water or some power is available no matter what the situation.) Is she living in an earthquake zone, a flood plain, a tornado area?

This is an expansion of my response to her.

I do not know where you live or I could be more specific. These are not necessarily in the correct order. All homes should have these, in my opinion. The brand is not as important as having the items there. You can use rechargeable or battery lights.The Energizer Solar Lantern This unit has charging options that include solar panels, crank, primary batteries and car adaptors.This is an LED lantern with adjustable light output.

If you live in a southern climate, using solar panels to keep batteries charged to power a 12volt Koolatron cooler would be a great addition so you could have cool beverages and keep some food items from spoiling until the power returned. The solar panel I've included has a regulator on it so the 12V battery of your car, truck or RV won't be overcharged. What you don't want is a dead battery when you need to leave your home for a shelter or to get supplies when the emergency is over. A less expensive solar panel is the 50 watt Go Power solar panel with regulator

1. Flashlight or flashlight lantern and extra batteries

2.Weather Radio and extra batteries

3.Emergency medical kit. Also include at least a 7 day supply of Rx medications that you or family members require.

4. A survival kit either made by you or a company that includes drinking water,food bars,etc. Survivor Industries makes a variety of survival kits for different needs. The food and water both have a 5 year shelf life. This is a 3 day kit for 2 people This is a 3 day kit for 2 people. For a remote location or a flood or earthquake zone, I suggest you plan for a longer time without access to fresh or frozen foods. Small Office or Family Emergency Survival Kit by Survivor Industries offers both a medical kit and provisions to keep up to 5 people healthy and fed for up to 3 days. Both food and nutrition bars are included plus a deck of cards, tissue packs, flashlight, radio, etc.

5. The Aqua Pod fits in a bath tub and gives you water storage if you live in a hurricane, tornado or flood zone where your tap water will either not be available or its safety is in question. This unit includes a hand pump. The capacity is 65 gallons, enough for a family of 4 for 14 days. The unit includes three liners.  

Thank you for your question and your entry into the Ask Barbara Contest.



120VAC/DC Converter for 5 amp or less 12V Thermoelectric cooler or warmer?

by Barbara 10. June 2009 10:19

Question about using a thermoelectric cooler/warmer indoors on AC power.

Q: "Which AC/DC converter do you suggest for a larger thermoelectric cooler/warmer that draws up to 5 amps? We'd like to use our cooler indoors as an extra fridge or pre-cool prior to going camping." Thanks. Thomas

Answer: Currently, Koolatron has two units that meet your needs. These are the Koolatron AC Adapter for 12V Cooler and Battery Charger, ABC-1 and the Koolatron AC Power Adapter for 12V Travel Coolers, AC15.

The ABC-1 is the Deluxe Version of the Koolatron AC Adapter is compatible with all Koolatron thermoelectric coolers. This deluxe AC adaptor does everything the AC-15 adapter does plus it is a 120VAC car battery charger. Power your Koolatron Cooler/Warmer at home or office with this AC Adapter. For use with all Koolatron 12V Coolers and warmers and other 12V items as well. Not only is it an AC adapter, it is also a battery charger for your car. Plug into the car's cigarette lighter and charge your car battery over night. You can use it to power all sorts of 12V items that require no more than 12V at 5A of power and use a cigarette lighter socket for a power source. It also is protected against overloading and overcharging. Converts 110VAC to 13VDC. Use indoors only.

The AC15 is not voltage regulated and depends upon the input voltage and the load current. The output voltage is not regulated and depends upon the load current: the output voltage may exceed 14 volts when load current is less than 0.5 amps. 5 amps power draw.The output voltage of the power adapter Important: This power adapter/battery charger is for indoor use only. Intended for use with Koolatron thermo-electric coolers: the user is responsible for evaluating the suitability of the product for use in other applicatDirections for Use: Place unit upright on a hard, flat surface with cooling vents unobstructed. Connect cooler to power adapter output socket first. Then connect the power adapter to an AC outlet. When disconnecting, first remove the AC plug first, then the DC plug. This unit has an auto-resetting electronic shut-down circuit for your protection and for the protection of the unit. A green illuminated LED indicates proper operation. When the shut-down circuit operated, the LED will not be lighted. Disconnect the power adapter from the AC outlet. Allows it to cool down for at least 10 seconds and the circuit should reset. The LED will again light. Any load that causes the LED to go off either draws too much current for the power adapter to handle or has a defect causing a short circuit..

Warnings are similar for both units for safety:

  • Do not operate in an environment where the unit may get wet
  • Do no operate in direct sunlight or near radiant heaters
  • Do not restrict ventilation above or below the unit
  • Do not operate without a load for longer than 15 minutes: Only for the AC15
  • Do not grip cords when disconnecting: grip only the plug and socket
  • Do not rotate the plug in the socket: push straight in and pull straight out.
Thanks for your question.


How Cool Does A Cooler Cool?

by Barbara 22. June 2008 08:07

Question about the product, Koolatron Krusader 12V Thermoelectric Cooler 52 Qt.

Question: Your information says these coolers keep items cool to 45-50 degrees below the ambient temperature. Does that mean if the inside temperature of my car is 80 degrees it will cool items in the cooler to 35-40 degrees? Thank you in advance for your response." Gary

Answer: We checked with Koolatron, the manufacturer of the Krusader and other thermoelectric cooler models. Here is their representative's response:

"Your customer is correct, the ambient temperature is the temperature within the environment where the cooler is placed. If the cooler is in his car, and it is 80 degrees, the Krusader or other Koolatron coolers will cool down to a low of 35 degrees inside the cooler. Please note that thermoelectric coolers do not reach freezing, so 35 degrees is the coldest the cooler will get inside. In other words, if the inside of the car is 65 degrees, the temperature inside the cooler will go down to around the 35 degree level, not down to 15 to 20 degrees F."

We recommend that you purchase an AC adapter and precool the unit before moving to your vehicle. During your trip, use AC to power the cooler at night if your camp site has AC available or use AC in your motel or hotel room.

Please contact us if you have additional questions. We sell several brands of thermoelectric coolers and warmers including Koolatron and Vector.

Sincerely, Barbara

How does a thermoelectric cooler work?

by Barbara 4. June 2008 12:22

Question about the product: KN-P27 Koolatron Voyager 12-Volt Cooler 32 Quart

Q: "How does a thermoelectric cooler work? I am considering purchasing the Koolatron Voyager but need more information." George

Answer: Thank you for asking this question. I did not know the answer so I went to the Koolatron site where I gleaned this information.

Thermoelectric coolers use a principle called the "Peltier" effect. In 1834 Jean Peltier noted that when an electrical current is applied across the junction of two dissimilar metals, heat is removed from one of the metals and transferred to the other. Koolatron uses this principle to keep the Voyager and other Koolatron thermoelectric coolers cold.

Thermoelectric modules are constructed from a series of tiny metal cubes of dissimilar exotic metals which are physically bonded together and connected electrically. When electrical current passes through the cube junctions, heat is transferred from one metal to the other. Solid-state thermoelectric modules like the ones used in the Koolatron coolers are capable of transferring large quantities of heat when connected to a heat absorbing device on one side and a heat dissipating device on the other.

The Koolatron cooler's internal aluminum cold plate fins absorb heat from the contents, (food and beverages): the thermoelectric modules transfer it to heat dissipating fins under the control panel. There a small fan helps to disperse the heat into the air. The system is totally environmentally friendly and contains no hazardous gases, no pipes no coils and no compressor. The only moving part is the small 12-volt fan.

Thermoelectric modules are too expensive for normal domestic and commercial applications which run only on regular household current. They are ideally suited to recreational applications because they are lightweight, compact, insensitive to motion or tilting, have no moving parts, and can operate directly from 12-volt batteries.

Advantages of a KoolatronThermoelectric Refrigerator (Cooler) Over Compressor Coolers (Freon Using), Absorption Coolers (Ammonia Solution Using) and Ice Chest Coolers:

  • Compact: More usable space due to small size of cooling components: thermoelectric module is the size of a matchbook.
  • Weight: Weigh 1/3 to 1/2 as much due to lightweight cooling system. Ex. A 36 qt. capacity unit weighs only 17 lb.
  • Lower Cost: 20% to 40% less expensive than compressor or absorption units.
  • Portable: carry with one hand. Unaffected by motion or tilting.
  • Low battery draw: average is about 4.5 amps - less than your car's headlights
  • No Melting Ice: Food and beverages are kept cold and dry. Helps preserve ice 3 to 4 times longer than an ice chest.
  • Cooling Performance: Koolatron units will refrigerate in sustained ambient temperatures of up to 95 degrees F. If Koolatron coolers are kept full, they will refrigerate satisfactorily even if peak daytime temperatures reach 110 degrees F as the temperature of the contents lags behind the ambient. The food will be just starting to warm up when the air cools off in the evening which will bring the food temperature back down to normal.
  • Reliability: Koolatron thermoelectric modules do not wear out or deteriorate with use. They have been used for military and aerospace applications for years because of their reliability and other unique features.
  • Ease of Servicing and Maintenance: Koolatron units have only one moving part, a small fan with 12 volt motor which can easily be replaced with only a screw driver. Most parts are easily replaced by the end-user.

I hope this answers your question about not only how a thermoelectric cooler works but also why this is the best choice for most people needing a portable cooler.


Can you set a temperature on a Koolatron cooler?

by Barbara 19. March 2008 08:41

Question about the Koolatron Voyager 12-Volt Cooler 32 Quart

Q:"Can you set this cooler to a certain temperature?" Kip

Answer: No, there is no temperature setting on the Koolatron Voyager and other non-commercial Koolatron cooler units. These units cool 45 to 50 Fahrenheit degrees below the ambient temperature. "Ambient temperature is defined as "the temperature of the medium surrounding an object or. . . the prevailing room temperature." So if it is 90 degrees in your car, the temperature of the cooler will be 40 to 45 degrees F. We do suggest you pre-cool the unit using an AC adapter. This unit also can serve as a warmer to keep food warm for a picnic or other event where food will be consumed within 45 minutes or so.

If you have need for a commercial cooler, please contact us with your requirements and we can get a price for you dependent upon the size of the unit.
