Can I have this charger hooked up to the car on the 50amp setting and turn the engine over without damaging the charger?

It takes lots more than 50 amps to start your car. I do not think your car will even turn over, or if it does not very well. This charger is not really intended as a car starting unit, and if you use it that way you just may "smoke" it. If you have the bucks and balls to try it let me know how it turns out.

I have had this charger hooked up on a dead battery, at 50 amp setting. After a few minutes charge, I tried it. It did not burn up, but 50 amps will not crank an engine. It takes about 450 amps. Let it charge a few minutes, then try again.

This charger only operates for 60 seconds @ 50amp & shuts down for 180seconds (3mins) to prevent damage - if your battery is not totally trash then 50amps will crank engine & usually start car so it can charge on it's own ~ this feature is only intended for for situations when one does not have sufficient time for a proper charge~ such as running late for work & need car running instantly ~ continually charging a battery @ 50amp can result in injury or explosion~ this is a charger & proper time for charing is ALWAYS recommended

Use of this charger can only be to maintain the charge, not starting the vehicle.

Using this as a "power supply" is not recommended with sensitive d.c. electronics (radios, test equipment) and such. Car battery chargers don't have "clean d.c. output filtering. But you can attach charger to an auto/marine, etc. type battery and then connect to the battery then. The battery acts somewhat like a filter and your current should be acceptable. I've only done this in an emergency 2 or 3 times in the past 50 years, but it works. Otherwise straight out of the charger could damage "high end" electronics. Straight out of the charger to a radio, you'll probably notice an over bearing loud Hum coming from the speakers, that's unfiltered d.c. Good luck in your experimenting!!!

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine

Yes, use the charge controller and configure according to the directions that come with it. I got the 30 amp one.

i am not a mechanic, nor electrical engineer, however, I doubt that the current required to charge this unit will do any harm to the battery. For a more qualified answer, you might check with your mechanic or dealer that sells auto batteries.

No, it is not designed to handle that kind of amperage. It is used for finding shorted circuits, and for powering up circuits to operate low amperage solenoids and relays and switches.On second thought, you could induce 12 volts to the ignition switch circuit to power up the solenoid, just don't use the Power Probe to bypass the solenoid.

Yes, the charger converts from the car's 12 volt system to 5 volts, the standard USB port voltage.

there's nothing to over heat, the charger only works when the two inductor comes together. hope this helps

Yes you can as long as the car is running. It will not charge if the ignition is off! it uses no more power than a phone charger and heats up nice, not too hot like some!

You can, this charger will maintain the battery and never overcharge or destroys the battery

Yes, you can. Check out this link for a better explanation. http://ask-leo.com/can_i_use_a_charger_that_provides_the_same_voltage_but_a_different_amperage.html

just look at the specs for your charger. if the output VOLTAGE is the same, it should be ok. Lower or higher amperage is fine, tho lower amperage= slower charging. If it doesn't give amps, but only watts and volts, as long as the Volts are the same, you're good to go- tho, again, lower watts= slower charging. That said, the car charger matches the specs for my 2011 macbook air, and i think it STILL charges slower than my regular charger.

The higher the amp the more electrical energy is sent. The car will charge faster.

Yes and no... If you vehicle as cigaret light with constant 12V without key in the ignition then you can. This charger put out max 5amp or so it is okay to use. If you have to use with ignition on then you are wasting the charging so I would use battery terminal

The only way I know to charge this is to plug it into a 120 volt line. But I can tell you that it has worked when other smaller chargers would not start an engine. The other day I helped out a workman whose truck battery would not start, and the small unit he had would not turn the engine fast enough, or supply the amperage for the system. I hooked this monster up and the truck started in one second.

Yes, this is a handy 2 amp charger that will prevent you from toasting this small battery. These batteries are easily damaged using higher amperagechargers.

I can't see why not either. While driving, this gadget and the car's battery are both being charged by the car's system, which has many times the necessary output to run everything all by itself. You wouldn't want to use the inverter when you were charging the battery from the wall charger, but there's no reason to try that in the first place.
