What is the best way to charge AA batteries with a car battery?
I have a 1-hour charger that does 4 batteries. I will need 4 batteries a day. I can't run down my vehicle battery while out in the boonies. I was going to plug the 1-hour charger into a power adapter. That seems quickest and most efficient. Any better ways to do it?

The best way is with a high quality charger that runs directly off 12 Volts DC. Using a power adapter to make 120 Volts (and some heat.....the heat is a clue you don't want) is a flat out loser. Not to mention the wall wart itself. Charger speed is not really an issue, efficiency is. You want to use as few Watts as possible putting the required Watts back into the batteries.

Back in my traveling days, I used to do this sort of stuff using a motorcycle battery which I'd plug into the cigarette lighter jack when on the road to recharge. Never had cranking issues that way. Today I'd probably use a 12 or 20 Ah gel battery, which are common and cheap. If the battery is good in your ride you should be able to pull 15 or 20 Ah out and still be fine unless it's really hard starting?

CHarger speed/time is the issue for me. I need my batteries charged in around an hour. I can not run down my car battery. Plus I am in no way going to buy another charger. I already have to buy a power inverter. I already have 2 chargers a high quality 1 hour charger charger and the charger that came with the MFLB; they both work great. Best method includes the cheapest.

Suit yourself.

Next time you ask a question like "What is the best way to charge AA batteries with a car battery?" I'll try to remember not to waste my time answering/trying to help.

Good luck with it.

How do you expect to charge 4 batteries in an hour without running down your car battery or running your engine? You have to get electricity from somewhere, I'm not sure you'll be able to find a cheap method to make that happen. And like OF said (he knows his stuff about electricty), using a 12 volt car jack to produce 120 volts for a standard wall charger is a big waste. You can't get fast, low power, and cheap all at the same time.

It's 4 AA batteries. I hope my car battery can handle charging four AA batteries. I am going to plug the charger into a power inverter and that will either be enough to charge up a few AA batteries or it won't Idf it isn't then this mflb is usless for camping if you have to buy more expensive shit for it. .I will either be charging batteries with my 1 hour charger or the MFLB will be sitting back at camp and I'll smoke a good ole joint.

Now you're telling me I have to buy another charger? fuck that i have two already. if the mf charger uis a pos then this thing is useless for camping.

YEah DOn't answer if you are going to get upset because I didn't agree with you that your answer is best. It isn't best for me . I don't want to spend any more money on this thing. So my solution is better. Sorry. deal with it. ANd if using a power inveter and a charger I already have doesn't work I'll light a bowl.

Or you could buy a butane vape @1flyfisher ?

Also lets not get arsey. @OF has a lot of kudos around here but he doesn't tolerate fools. Be grateful for his input whether it's useful for you or not. believe it or not he does know his stuff.

I'd say why not give it a go and report back to us with charging times etc? As long as your car's running there shouldn't be a problem running down your battery. So maybe an extra jerry can of petrol/diesel will suffice to help charge your battery? Not the best solution but it's better than walking back from the lake lol

Then , just buy more batteries , you will eventually anyways .
Have them pre-charged before you leave your house .
I have 8 batteries in rotation with a 4 slot charger .
You may want to have more batteries for your camping trip .

First off I'm a retired Master Electrician. I got my Masters licence in 1970. This said so you guys won't think I'm blowing smoke.
Almost all chargers (not all you have to look), have an input for 12v, even the charger that comes with the LB, (look on the bottom). The MAHA C-9000 has a 12v input.
As for myself I have a Stanley 300 amp jump start battery, that has a 12v outlet, (cigarette lighter), and a USB outlet. You can charge it by 120v, or 12v, as well as jump start your car. Most people do not realize batteries charge faster on DC than on an AC adapter. Mainly because you don't get pure DC from an AC adapter. You get pulsing DC, (one reason the PA pulses on max when on the AC adapter). To get pure DC from a wall-wart is asking a lot in such a small space. I use my PA on DC. It never pulses on the jsb. I use the jsb to charge my cell phone. It's about a 1/2 to 3/4 hour faster.
The MFLB is not that complicated. There is less than a dollar in parts in this thing. Ohms law says if you know the voltage and the resistance, then you can calculate how much heat you will get. The spot welding of the screen can be different from box to box, so there is no set way to use them all. Just remember to shake between sips. The herbs need to touch the screen to be heated properly.
Ok I've said my piece. Be easy on me I'm an old man. I can just turn my deaf ear. ;-}

Anyone get an etched lid? I am regretting having my lid etched as it obstructs the view of the vapor building up.

I have a few without and one with. I've learned that no matter how much it bugs me, it still performs the same. I have the flower so I REALLY can't see anything.. My buddy has a Celtic tree and you can see the trench just fine from sides but not front and back

I just picked up the PA and was using it for the first time last night. The etching made visually judging the vapor production at various settings a bit harder than I imagined.

I feel like it might be more of an issue when judging how tossed your trench is (making sure any darker stuff is on top). While I've definitely dabbled in looking at the trench when vaping, I go mostly by taste and feel. In my experience by the time vapor starts showing in the trench the box is already super close to combustion. With a smooth consistent draw hardly any vapor shows in the box. What I've found to really help judge vapor production is to hook your box up to a water piece or j hook. Then you can see exactly how much vapor is coming out of the box at any given time, and adjust your technique accordingly. The Orbiter is just about perfect for this :D

Also, here's my full setup, PA included (finally!). Other accessories not included. :dog:

So what is the cheapest easiest quickest way to charge my batteries from a vehicle. I have a brand new quality battery in my rig. I was going to get this item and use it with the charger I have. I can start my vehicle before and after charging. In the winter I often fire up the vehicle and let it run 15 minutes to heat up the interior. I run the vehicle a few times in the evening to stay warm. I don't want batteries on a fuckin charger for hours or over night. I have a 1 hour charger for the last 10+ yeqars and it works great. I do not want to dump any more money into this. I have spent enough already on this thing. http://www.amazon.com/gp/product/B0040U3MI8/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=AWZ3LXPHZK09
Will this not work? I bought this damn MFLB thinking this would work.
I figured another $20 which I am good with.


Does this power inverter not provide enough energy to charge 4 AA batteries. It has good reviews. dOes this thing not work with battery chargers?
I am ready to just say fuck it and plan on smoking my pipe while out in the kayak. this pos mflb came with a car adapter. Is that not going to work either?

Anyone get an etched lid? I am regretting having my lid etched as it obstructs the view of the vapor building up.
I was thinking of this yesterday. I am glad I don't have an etched lid and wouldn't want one. I have to be able to see in there and align my herbs. I have to bang my mflb hard on the table or something to loosen the herbs and shake it real good, otherwise they will stay stuck in the corner cracks. The upper sides of my trench are a bit concave and herbs get stuck up there so I have to jiggle them into place. No way on the etching blocking my view. I also like to see how brown they are. I can pretty much tap the mflb lightly against something or tap it with my fingers but after I do that I like a visual check before my next draw.

lol this guy

It's like you are threatening to combust if people don't provide a cheap and fast way for you to charge your batteries using your car. By all means, blaze away. Nobody cares

Here is a golden lesson I learned from years of modding cars for power: fast, cheap, and reliable. Pick two. You just can't have all three.

LOL I think you need to put down the herbs you are tripping. Thgreatening to combust?....lol that's funny.

I don't want to buy more shit for this thing. I don't want to fuck with the batteries really at all. I hate charging batteries and screwing with fucking batteries. I take 8 AA batteries with me for my depth finder and they work for an entire trip so no recharging. I hate dealing with the batteries I already have to carry and screw with 8 batteries now I have to recharge batteries for the mflb. That just more shit I have to deal with while trying to camp and fish in winter conditions. I do not want to buy all sorts of shit for this thing like fancy battery chargers or water pipes or add ons or anything I don't have to. I just want a simple product for use while remote camping.


I saw solar AA battery chargers. Maybe fuck the car battery and rely on the sun.
I want the cheapest, easiest, fastest, bestest way.

I am getting the power inverter, then maybe a solar AA charger. If that can't charge a fuckk AA battery I am throwing this fuckin MFLB in the lake.

Just Use your power inverter since your mind is made up already or smoke a joint who here really cares.
I'd say most people think ahead if going off grid and pick up 6 to 10 batteries at least( if you don't like carrying extra batteries I don't believe the MF is the right vape for you to use in these situations)

I know if need be I have a 500 amp jumpstarter/powerstation always in the car(unless its charging on AC) that'll probably run the Launch box with the PA for days worth of use.

But I Believe Your Inverter will work Best, For You. Maybe no one else here who has experience with these things but yes Best For You !

Maybe look into Butane powered vapes for camping and fishing.

I love smoking my pipe. So I always have back up.
Jumpstarter battery backup are a good way to go and also a good item to own for remote camping.
But you are right the power inverter is the best way to recharge the AA batteries.
I am going to try a power inverter, I said that.

why did you bring a MFLB on your trip with you if hate batteries so much? You knew in advance that you were going to have to carry them around with you and charge them.....then you didnt bring enough pre-charged batteries so your complaining about having to buy extra stuff to charge the few batteries you do have?

I would say its safe to assume the MFLB just isent for you or you need to just buckle down and buy a bunch of spare AA to make sure you dont have to worry about charging at all.

You're really making a mountain out of a molehill. Despite the inefficiencies with your approach (and there sure are some of those), simple math will tell you that you could charge your AA batteries several times. A decent car battery will have at least 60 Ah, but 4 AA batteries for the LB only need 10 Ah for a full charge from completely dead. If you run your engine for a few minutes you restore part of that capacity as well. If charging your LB batteries drains your car battery below starting power then I suggest you should be looking for a better car battery.

Frankly, you didn't do enough homework. The LB is a marvelous little device despite you referring to it as a "pos"; however, batteries and charging them will always be an issue if you make long trips away from conventional power sources. Sell your LB and buy yourself a Hammer with an Ed's stem and a can or two of butane.

Another suggestion: stop after typing a post, hit the LB, and relax. Then edit your post and tone down the frustration and hostility. You don't want to break our Be Nice rule, do you?
 
@1flyfisher The Solar charger will take 10-12 hours of full sun to charge 2 batteries, good luck with that.
Thanks. It looks like it will work real good.
My God is the Sun.

I would need like 100 batteries for 3 weeks of camping.

I did tons of homework. Way too damn much on this thing. It has flaws and it has some good things about it. No matter how much homework you will never know till you try own one. I would not recommend this pos because it has too many of them.
I hope someone invents something better than this mflb. then I will buy another vape. I will use the mflb a little but it kinda sucks and the thing juust doesn't get you baked like a good toke. Plus it's a different high and less body high which medical users need.

That is what I was saying. Then someone gave me some convoluted technical bs that I needed a new charger and someone else said I needed dozens of new fucking batteries.
The power inverter will work. It'll work.
Positive vibes man. Positive vibes.
