If you have a 12volt standard electrical system in your vehicle.
It is both positive and negative. The travel inverter converts this 12 volt DC current into 110v 60hz AC current so you can plug in your electronics that require standard household current to charge/operate.
There is a built in USB port if you device will accept this for 12 volt power. It also has the power oultet with ground for 110v 6hz power.
Link below has a good picture and description. Hope this helps!

Trying to charge battery for first time. It says connect two red connectors. Do you charge it first then connect the connector afterwards?


1. I assume this is a car battery so the first thing you do is to disconnect the vehicle cables from the battery terminals. The negative first and then the positive. The positive terminal is marked with a plus sign ...+ ... When refitting the cables to the
battery after it is charged you fit the positive cable to the positive battery terminal(+) first and fit the negative(-) last.

2. Now that the battery is unconnected from the vehicle you can fit the charging cables to the battery terminals. The charger you have should have 2 cables leading from it , a positive with a red plastic insulation on the clip and a negative cable probably with black insulation on the clip.The instructions with the charger will tell you in which order the cables are to be attached to the battery and the order you remove them. Each of the 2 cables has to be clipped onto the correct battery terminal. The positive cable(+) from the charger goes to the positive battery terminal (+)and the negative cable(-) from the charger goes to the negative battery terminal(-).

3. Once the cables from the charger are properly connected to the battery, you can plug in the charger and turn on the power.

4. Batteries generate explosive gasses when being charged and it only takes one small spark to ignite them. Don't reconnect the battery after charging for a half hour or so and make sure the area where you are charging is well ventilated.

How to Charge a Car Battery Using a Battery Charger


If you find yourself with a dead battery in your car and have access to a battery charger you are only some time away from being on the road again. Whether you are using a small car charger known as a trickle charger or a larger unit on wheels, you can charge your battery effectively. There are safety concerns though. Be sure to check the warnings
1、Locate the battery or remote charging point by consulting the owner’s manual. You can also open the hood to find the battery. The laptop battery may be under a seat, in which case a charging point may be provided under the hood.
2、Remove any plastic covers that may be protecting the positive and negative posts of the battery. Just push the covers to the side as they are usually pliable. Note the location of positive and negative terminals signified by a plus and a minus sign respectively.
3、Locate the laptop car charger so that its cables will reach the battery. Make sure your charger will reach an electrical outlet. Add an extension cord if needed.
4、Place the clamps of the charger on the battery making sure that the red handled clamp goes to the positive battery post and the black handled clamp goes to the negative laptop batteries post. If you are not sure, trace the cable attached to the clamp back to the charger and look for a positive or negative designation. If you are still not sure, stop and seek professional advice.
5、Plug the charger in, making sure that the selection switch is set to off.
6、Select the appropriate voltage and or rate (almost all cars have a 12 volt system). If time permits choose the slower rate and plan on charging the battery for two hours. This selection will turn the charger on. If the charger has a timer, set it.
7、After charging the battery, unplug the charger, disconnect the charger’s cables and start the car.

Battery went dead put charger on battery and charger shuts off.


the reason for this may be the way you have attached the battery charger leads
charging batteries require the positive lead of the charger to be clipped to the positive terminal of the battery
likewise the negative lead of the charger goes to the negative terminal of the battery
I suspect that you are hooking positive to negative in which the charger will go into overload protection and shut down.

Charging the battery


If you have a battery charger, remove the battery cover to expose the battery terminals then you can connect the battery charge to the battery.
Make sure you connect the positive lead from the charger to the positive terminal on the battery and the negative lead from the charger to the negative terminal on the battery before you power up the battery charger.
When you have finished charging the battery, power off the battery charger before you disconnect the leads from the battery.

The charger that comes with Homelite 24v mower is crappy. I've gone thru 3 of them. What's a better alternative?


I have used a DieHard portable battery charger (model 200.71222) for several years to recharge my 24-volt, 18-year old Craftsman mulcher, model 315.370270. This is after the on-board charger died. I just disconnect the link between the two 12-volt batteries and remove all other battery connections. Then connect the charger leads to the positive and negative terminals on one of the batteries before plugging in the charger. I put the settings on the charger at conventional low maintenance and 2 amps. Charge one battery and then the other (assuming you have two 12-volt sealed lead acid batteries like my mower). I use binder clips 530-t.jpgfrom an office supply store to hold the battery wires on the terminals when I'm mowing...makes it simpler to remove and reattach for charging instead of the nut-and-bolt connectors that came with the mower.

Need to charge battery on my chevy venture. Please show me how


Okay... One can not see the negative battery terminal so.... Connect the negative clip from your charger to the chassis and then remove the RED plastic cover in front of the black relay box above the battery OR the plastic cover from the positive battery terminal and connect the positive cable. Make sure you have good connections by watching the meter on your charger. Then plug in the charger and turn it on. Charge time depends on the strength of your charger. I'm going to go hook mine up again because I need to go out for a bit. I don't think I'm going to like changing this battery..... Just thought I'd share..... Good luck.

My 15 min. Duracell charger keeps blinking-won't work...


When the duracell lights blink during charging, AT YOUR OWN RISK, try a reverse charge. Instead charging positive to positive and negative to negative, try positive to negative and negative to positive. I did this for 2 minutes. This solved the problem. After the 2 minutes, I gave the batteries a normal charge. You will have to force the battery and charger contacts to touch.

Can't connect charger's cables to battery without sparks


NEVER connect positive to negative. You'll damage your electrical system in the car or fry the charger.

It is best to put the positive on first, and then the negative. Remember, it doesn't always have to be the negative post of the battery, it can be a really good ground on the bare metal of your car.

But sparks just go along with it - don't let them scare you. But I always connect the clamps first, then turn on the charger, with the dial on "off". Then make sure of the 6/12 volt settings, and the amp charge you want to put on. A long slow charge overnight fo 12 volt can be 10 amps. A relatively fast is 50. And then to jump it off, go to the setting.

Make sure the battery being charged is sitting in wood, not concrete. If you have the old fashioned battery with removeble water caps, don't breathe the vapors.

Charge battery


Do you have a battery charger? If you do, connect the red(positive) clamp on the charger (+) to the Positive (+) battery post. Then connect the black(negative) clamp on the charger (--) to the (--)(negative) battery post. Make sure these are hooked up this way, if they aren't, you can damage the car's charging system (big bucks to fix). When you are sure the charger is connected to the battery properly, plug the charger in. It would be best to let it charge overnight. You must then find out why the battery went dead, otherwise, when you go out someplace and turn the car off, you may not be able to start it up again. If it's the original battery it's time to get a new one. You can drive to a major parts store, they will check the battery and car's charging system to see what's wrong for free.Good Luck countrycurt0
