Will the 25 amp Stanley do better on car start with a dead battery vrs. this 15 amp Stanley ?

A charger capable of charging at a greater amp rate will charge a dead battery quicker than a lower amp rate charger. It is important to look at what the starting amps are available on the charger. The quick start timer depends on the charge rate of the charger, hence the 25 amp charger will have a shorter quick charge rate than the 15 amp charger. I note that my 15 amp Stanley charger does not have an engine start function, just a quick start timer (which tries to boost battery charge in a short time to enable rapid draw of power during a start)

The 15 amp does not have a "car start". That being said it is always faster to charge a battery with more amps.

I'm not an expert and I'm just giving my opinion but I don't thing that would work. Using the battery clips would be better because 250 watts on a 12 volt DC supply is 20.83 amps. Most cigarette lighter circuits are only good for 10 to 15 amps. Because of the continuous draw of the heater I would suggest going to a direct line to the battery. Your other concern will be the amp-hour rating of your battery and how long of a run you'll get before needing to recharge (assuming you're running off a battery and not an engine driven power supply). Just my thoughts, good luck.

It will charge a dead car battery with in 13 hours depending on the battery's capacity. It will not jump start a car though.

No. Starting a car requires 400-500 amps. The maximum output of the Yeti is 14 amps.

It will if the battery is still good it will take a while ,they only put in 1.5 amp .

I just looked at my charger, its 12VDC / 2 amp, same output as a car cigarette lighter. It is a Positive TIP (center) and Negative Outside jack. As long as you get an adaptor to fit unit and ensure Positive TIP, it will work. As far Amps, a car battery has as much as 500 amps, but don't worry, your box will only draw the 2 or less amps, only what it needs of the available 500 amps.

This could "jump start" any car, but beware that the battery in this is very small (like rated at 5 amp/hour). I have another brands "jump-start" that has a 18 amp/hour battery and just to experiment, I disconnected my car battery and hooked mine up. It started the car (a ford festiva 4 cyl), but the starter was barely turning the engine. If that's what happens on a small car with a much bigger battery than this, I'd be very surprised if this would be able to start a V6 or bigger engine with a fully drained battery (like from leaving the lights on all night). If you left on some lights while in a movie for 2 hours it may have a chance, but that's all I'd expect. Feel free to look at reviews of this and similar priced ones (that have a similar battery) to see if there are a fair number of others saying the same thing I am.

I'm not sure, as my husband is using the cooler in his semi, which I guess has several batteries, so the power it would draw would be minimal. It is a small size cooler though, so I doubt that it would draw a lot of amps from a regular car/truck battery.

yes it will only give u 25 rms through the factory stereo but if you run an amp kit to the battery it will give u better performance. i did it both ways an i could notice a big difference with it running to the battery for power. Heres the amp kit i used crutch field advised.http://www.crutchfield.com/p_700POWERPK/Power-Pack-Connection-Kit.html

yes, the 1 amp difference should not matter - it will actually make the battery less likely to fail, as it will be able to recharge more efficiently. My old battery was 4 amp, and this 5 amp replacement works like a charm.

This can provide some power for "jump-starting" any car, but realize that the battery in this is the size of what you'd see on a riding lawn mower or generator. Since it's really not that big, I find the "Gives you 500 amps" labels a pretty big lie. I hooked up another brands unit like this to my car and disconnected the regular battery to try it out. It started the car (ford festiva 4cyl), but the starter was slow barely going. I believe this has a 18 amp hour battery just like mine. If I had a fully drained car battery (like from a light left on all night) and I left it connected while hooking this up, I'm afraid the drained battery would "steal" most of the charge from this battery and probably make both too weak to start the car in as little as 30 seconds. So I'm not keeping my hopes too high on these, especially if talking about a fully drained car battery (whereas if you left lights on while in a movie for 2 hours it has a good chance of starting it). Feel free to look at reviews (both some low and high ones) and see if others suggest about the same thing. Also FYI if you want a way to compare these to your car/truck battery, here's one OEMs definitions of rating batteries: CCA (Cold cranking amps) = The discharge load measured in amps that a new fully charged battery can deliver at 0 degrees F for 30 seconds and maintain a terminal voltage greater than 7.2 VDC. CAA (Crank assist amps) = The discharge load measured in amps that a new fully charged battery can deliver at 70 degrees F for 5 seconds and maintain a terminal voltage greater than 7.2 VDC. These battery packs are labeled using the CAA system, so to convert to CCA dividing the "500 amps" by 6 will give you a closer number (and I get that 6 factor from the 30 sec test of one versus 5 sec, not to mention temp factors).

I believe the statement is referring to the starter battery of your vehicle. You would not want to risk running your starter battery "dead" or too low, as you will no longer be able to start your vehicle -- this is not good, as you will be stranded at worst, or inconvenienced. If the car is running (as in a tripp down the road), it is fine to plug it in and use it while the engine is running. If you stop for 15 minutes or so, it should be fine, as long as your battery is in good working order. Most newer vehicles have a ignition powered 12 VDC socket, and will turn off when the vehicle is "off". This is not guaranteed, so use your best judgement and consult your owner's manual for details.

No because the input amperage output is so low it cannot over charge a car battery. It also has a diode to prevent reverse flow when it is not charging. A dead panel should not drain a battery any faster than the battery would drain on its own without the panel hooked up. If it is dead it is dead. Now if only the reverse diode was dead than maybe it would drain it at night. So far my panel has worked great.

Be sure the circuit (fuse) has the capacity to handle the load. I have an aux. battery in my van and charged from a Wagan Quick Jump Starter and it blew a 20a fuse after a couple of days of plugging it in. Be sure you isolate the aux battery in some way or your batteries will try to drain each other.

I have not had the opportunity to use it. It is very light weight.It is for small cars and anything up to 300 amps. It might starta V8 truck if the battery is not run down much.

Probably but not if you crank it up much. This is for a steady draw from light bulbs. The only way to steadily power a car stereo is with a high amperage power supply. The easiest method is what I do in my golf cart. I have a marine deep cycle battery that runs the radio, then when I am done, I put it on charge overnight. For longer periods to keep the battery charged up I have a float charger. Yes this is a hassle but car stereos draw a lot of power at only 12-14v so they need a lot of amperage to crank them up. Easiest thing is to get a good sized (it should weigh a few pounds minimum) power supply. A battery charger alone will buzz like crazy and not be good for the constant amp draw.

only if your car's battery is old, and on its last legs. it WILL NOT HURT to have the engine running, but it is not necessary unless your battery is old and so weak that it might not start your car if you ran this compressor for 5-10 mins. any battery in good shape will handle it without the engine running.
