Q: If you have a "dead" battery how are you supposed to charge the "charger" to jump your car, without a "good" samaritan?
A: When you first receive the SelfCharge Auto Jumper, charge its battery in your home. Then, transfer it to your car and keep it there in the event your car battery dies. If you were to use the SelfCharge Auto Jumper to recharge a cell phone, for instance, you could recharge your SelfCharge Auto Jumper using the cigarette lighter socket in your car while your car is running. It's a very versatile product.

Q: After initially charging the SelfCharge Jumper, how long does it keep its charge? Would it be still fully charged in 6 mo? 1yr? 2yr?
A: The SelfCharge Auto Jumper will hold its charge for 3 to 6 months. The charge will gradually decrease over time, but every few months you can plug it in to recharge so that it is always ready should you need it.

Q: What's the maximum amount of time it takes to charge the unit plugged into the cigarette lighter adapter?
A: It would take 30-60 minutes to charge the SelfCharge Auto Jumper through a cigarette lighter. This should only be attempted while the car is actually on, as you don't want to drain the battery unnecessarily.

Q: Jump-starting a "weak" battery is all well and good. But will your product still work when the car's battery has gone completely, stone-cold dead?
A: While the manufacturer states that the SelfCharge Auto Jumper can charge a dead battery, we suspect that there's a "degree of deadness" at which this charger will no longer be able to restart your car (where regular jumper cables may still be able to do the trick). The beauty of the SelfCharge Auto Jumper lies in the fact that it will work in most situations, it doesn't require outside assistance, and it can also charge your cell phone and other small devices.

Q: Hello, did you say it takes 30 to 60 minutes for the battery to charge? Thank you Merci ! lauryv@3web.net
A: It takes 30 to 60 minutes to initially charge the battery in the SelfCharge Auto Jumper. When it is fully charged, it should only take approximately 10 minutes for it to jump your car's battery.

Q: Will this work on Hybrid technology cars?
A: The SelfCharge Auto Jumper will also work with hybrid cars as long as it is plugged into a cigarette lighter with at least 12 volts.

Q: is this only for US Cars or will it work in cars in Europe? Thanks!
A: As long as your car has a 12 volt outlet, the SelfCharge Auto Jumper will work no matter where the car was made.

Q: I have a car that "switches off" it's power ports and cigarette lighter if the engine is off. Is there a way to still use this?
A: If your car turns off your power ports and cigarette lighter when the car is off, there is not a way for the SelfCharge Auto Jumper to bypass that, so it would not work in your car. If your car functions like this, we recommend that you purchase a Power Dome EX, which can also jumpstart a dead battery.

Q: I would like to know if this product is good to use on just cars or would it work on big trucks with bigger engines? Also, what if the temperature is really cold outside. Will the charger hold?
A: The SelfCharge Auto Jumper was made specifically for cars and SUVs. It is not meant to be used for larger trucks. Cold temperatures will not have an effect on the charger.

Q: You note that this won't work on a car that switches off its power ports when the car's off. Will this work if those power ports are switched on when the key is turned to the Accessory position?
A: According to the manufacturer, the SelfCharge Auto Jumper will work if the power ports are on when the key is in the accessory position.

Q: After it is fully charged how many weeks or months can elapse for the battery to be useable to charge a car battery
A: The charge will deplete over time, which is why it is suggested to top-off / re-charge the SelfCharge Auto Jumper every several months.

Q: how often can you use this product/how many times can you charge/recharge your battery?
A: According to the manufacturer, the SelfCharge Auto Jumper can be used up to 200 times.

Q: do it really work?
A: Yes. The SelfCharge Auto Jumper is basically a large rechargeable battery. As long as it has a charge, plugging it into your cigarette lighter will transfer that charge to your car's battery.

A: The SelfCharge Auto Jumper is designed to work with both cars, SUVS, and station wagons.

Q: How much does it weigh? Regards
A: The SelfCharge Auto Jumper weighs about 2 pounds.

Q: Does this really work is my question...I thought the cigarate lighter drained the battery not the other way of around.
A: Yes, it really works. Your cigarette lighter can do both.

Q: What is the amp load of the starter unit? Is there a way to know when the unit needs to be re-charged? I have a trans Am with the High Torque starter. Will this unit work on that? Thanks. DP
A: The SelfCharge Auto Jumper uses 5 amps. The unit should be charged 12-24 hours when you first receive it. It should be re-charged after it has been used or after 6 months of non-use. There is not an indicator on the unit that tells you when to re-charge. According to the manufacturer, the torque should not affect the SelfCharge Auto Jumper, as torque has more to do with mechanics than with the electrical system. The SelfCharge Auto Jumper will work with small and medium size car batteries.

Q: Please explain how the auto jumper works, and how it charges from inside the car through the cigarette lighter socket. Also, is there any warnings about the use of your product?
A: The SelfCharge Auto Jumper has a 5 Amp (14.5 volts), sealed-alkaline battery with the power you need to restart your car. Once the car battery has been jumped and fully charged, the SelfCharge Auto Jumper will begin to recharge itself automatically as you drive. There are no usage warnings for this product.

Q: alternater stopped working and battery died.could i use this to power my 4 way flashers and lights when i am hooked upto a toe truck
A: Yes, if the battery will accept a jump then lights and flashers powered by the battery will work. If the battery is completely dead and cannot be jumped, then these lights will not work.

Q: Does this company that makes this offer a money back guarantee?
A: The SelfCharge Auto Jumper has a one year manufacturer's warranty that covers manufacturing defects. Damages that result from misuse, accidents, or improper installation are not covered under the warranty.

Q: do you ship to UK and is it okay to use on our regular cars?
A: Electrically, yes. Physically, possibly. The outlet's center conductor has to be positive and 12 volts. There are 2 kinds of outlet diameters used in Europe. The United States standard is a little bit narrower than the European standard. If the plug allows you to change the diameter, then the SelfCharge Auto Jumper will fit fine. Yes, Vat19 ships to the UK.

Q: In question 3 you said "30-60 minutes to charge the device". Then later question you state that the time to have the device recharge the car's bat is 30-60 min. But ad says 10 minutes to charge car.
A: There seems to have been some confusion about which battery was in question. We have changed that answer to be more clear. To confirm, it takes 30-60 minutes to charge the actual battery in the SelfCharge Auto Jumper and only 10 minutes to charge your car battery using the SelfCharge.

Q: How much energy, measured in joules, is stored in this product (Self Charge Auto Jumper)
A: The manufacturer doesn't know the energy stored in joules, but we do know that it generates a total of 19.8 watts of power and its voltage output is 13.2V DC.

Q: Hi there, I was wondering how this will work if you have a cell phone and you normally have this plugged into the plug in. And how long does this have to be in the lighter to get a charge.

Q: Hi there, I was wondering once you have this charged up, will the cold draw the charges out, like it does with regualr batteries( flashlight) batteries.
A: Cold weather should not decrease the charge, but we would recommend giving it a charge every 2-3 months just to be safe.
