Im using this in my camper, and have my charger hooked to my aux battery, will the power flow to my starter bat as well? It doesn't seem to come on...

The current version will connect both batteries together when a charger is connected to either battery and providing an output voltage of 13.4 volts or higher. This will allow charging of both batteries with a single output charger.

It kicks off power to camper so u have to go reset it when it happens.....lets us know while we have been gone if it happens....we have ours in a permanent spot for season. It does what it is suppose to do!

In my Chevy pickup the plug is always hot, even with the key out of the ignition. So with a device plugged into the charger it will pull some power. Also the charger by itself will burn a tiny amount of power since it is converting DC voltage. This loss is tiny compared to a car battery but is an additional load if you don't run the car for an extended period. Its surprising how all the loads can add up and eventually deaden the battery.

I'm not an expert but I don't think this thing draws hardly any watts or amps etc. I lost my instruction booklet because half of the unit stopped working and MinnKota said it can't be fixed. I kept it to use as a trickle charger for cars, boats etc. I would think almost any generator would make this charger work. It' basically a trickle charger so it's gonna run your generator a long time to charge a battery a battery. You might want a more powerful charger depending on your use to shorten the generator run time..

How many watts of electricity do you require to run whatever it is you want to plug in? My grand kids used mine while on a camping trip recently and plugged in a boom box then their lap tops to play games. The vehicle's battery went dead in just over 6 hours. Lucky for them gramps packed a self contained emergency battery jumper to get the vehicle started up and back home. If they would've started the vehicle every hour for about 10 minutes, I think they would've been okay.

I am having trouble running it off AC power. The plug isn't designed well and it fell out of my power strip, so the battery ran out of charge totally. Now it's plugged in, but it doesn't want to work yet because the battery is not charged. So, it runs off the battery only, but you can try to keep the battery recharging as you use it by keeping it plugged in.

I used a car battery on it's own with out using the one in my vehicle when I was camping but the fan seems to draw very little from the battery, after my trip I hooked my smart charger to the battery and it didn't seem to really need much charging and I was running the fan every night for 3 nights.

Okay, do you keep the charger cable plugged into 110VAC outlet? I Don't, but I do plug it in from time to time. I (and neighbors) have used this device lots of times and never run it down. I've used the 110VAC outlet for drilling holes in fence poles and to run a pole saw pruning trees. I've used the "jump charge" feature for starting cars stalled on the road. I've charged a cell phone. I've used it for pre-setting our GPS. It is a little heavy to use as a flashlight but fills low tires on cars. Our neighbors like it a lot and have "suggested" what a great Christmas gift it would make (hint...hint). When we get our new Cessna, I will probably keep another in the luggage bay. Don't buy a cheap copy. Okay, do you keep the charger cable plugged into 110VAC outlet? I Don't, but I do plug it in from time to time.

You have to ensure the internal battery is charged or ensure that you have a good connection to the vehicle power source. If you have the USB connector you can charge it that way, although I never have been able to operate solely on the battery for any length of time.

No sweat...most important step that most people skip is hook up to battery with no less than #4 welding cable. # 2 is what i used and never had an issue powering anything. If you cheat on this, it will kick out on you constantly. Auto parts store will have dual batt terminals for a few bucks for hook up. Sweet unit...:)

+This unit does not store any battery power at all. Therefore to get any electrical "juice" from the unit it MUST be plugged in to an appropriate AC outlet. And, read about time limitations when you are calling for 50A output. Simply stated, at best it is a helper to your battery that is low. Best thing to do is to charge your battery for a while at 10A (more than 30 min), then switch the charger to 50A and crank your engine for a max of 10 seconds. If your engine does not start, switch back to 10A charging and allow battery to store enough "juice" (meaning Amps) to properly power the starter. All this presumes low battery is all that is wrong. Hope this helps. Randall

Just plug it in and its ready to go. It may need charged but mine didn't. Mine is a trickle charger very low amps. Good luck

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'm not sure but i'd use the optional AUX connection (the cable that plugs into the left side) because it shouldn't mess with the battery while it's charging.

I had a wall charger from walkera 25#10 and works great on this bat.Good thing stock 1 was junk. 3.7 volts dif miliamps works fine.

It charges a weak battery. If the battery is, for example 50% charged and it only takes several minutes to bring it back to 100%, some cells of the battery are dead rendering it useless. Won't jump start a car, not it's purpose. There are chargers/ jump starters, but be prepared to spend more $. It will, however,serve as a maintainer should you plan to leave the car sitting several days. It's all in the instructions. Be safe, read the instructions. On rare occasions batteries get hot (to the touch) meaning they are going to explode. I always touch the battery after a half hour or so.

Have 2 deep cycle bats in series-it will charge both at same time but,"ERROR" msg. stops the next phases of the charger's sequence.Charging each individually works normally thru the phases.A tech rep.& I spent 1/2 hour trying to diagnose problem.W/12v bats,charger gets confused-W/6v bats,probably similar results-only 1 way to find out it seems.Good luck.
