Is this charger efficent? I have one of those big charger with 2 wheels that use 500 watts to charge 15 to 20 amps on a 12volt battery.

Yes it is and its very well made..I was very impressed with its output power and digital display I have been a mechanic all my life untill retirement and would recomend this charger

Yes. I haven't had it very, but I have used it 3 times so far. Jump started my car, charged my other car battery and used it on my lawn mower battery to charge it as well. So far I love it. Very easy to use.

as mentioned in the specs it is 12A-30A for charging and 100Amp for starting. I have used on all styles of batteries and to jump without any issues.

i am not sure. but i have a 1.5 20 amp charger on a timer for one hour every day

I bought this charger because it charges ALL normal batteries 6 volt , 12 volt car , truck, motorcycle big and small tractors . Being a 1.5 amp charger it could take awhile to fully charge a low charged battery .

I keep mine on a Schumacher Smart Charger 24/7 and its been sitting for over a year on that charger. Used it as a battery backup system in a simulated "black out" scenario last weekend. Ran 5 light bulbs, a HAM radio, and charged electronic devices off of it. Pulled very little voltage and after running it for hours the monitor I use still showed an full charge. All that to say, the battery seems to be holding at peak efficiency.

I think you mean amps, not watts. It is supposed to trickle charge slowly. Borrow or buy a3 amp charger for this battery. 10 amps would ruin it.

I would not reccomend it, 500mah charges at .5 amps which is really too high and will shorten the life of your battery and possibly cause a fire if you still have the stock hubsan charger i would use that.

It should be similar to your charger. If you use a two amp port it might be quicker if the device allows it. I have never timed it versus my charger.

It depends on your charging habits. If you have time for an overnight charge, it will do just fine. If you need it to charge more quickly get a higher amperage unit. how many amps was your original charger?

The rule for large AMP hour batteries, such as yours, is to use a charger which puts out 10% of your battery's AmpHour rating. Since your batteries are 200AH, you would need a charger which puts out ten percent of 200... which is about 20 Amps. It doesn't matter that you are using two batteries... the calculation is still 200/10=20This 12 amp charger may, or may not, be capable of keeping your high amperage AGM batteries free of sulfation (which is why the higher amperage charger is recommended) Your best bet is to use a charger which puts out as close to 20 amps as possible.

It is a very good charger, i us it on only one 12v battery currently, but i see no reason why it would not maintain the charge on your batteries as long as they are hooked as a 12v system, i am sure it would be more effective it you did one at a time and cycled them through

According to the very small name plate the rating is 5.1 volts at 0.85 amps. If you need more current many two port chargers deliver 2 plus amps. Search Amazon for "USB Charger" I have one from POWERGEN.

Probably yes, as long as there were no other major loads on the generator. This unit draws a maximum of 13 amps at 120 VAC which equates to about 1560 watts, make it just over 1600 watts if you account for the charger efficiency of >93%. Obviously these numbers are based on maximum output form the charger (100 amps). You may want to consider a power conditioner in between the generator and the charger, depending on how clean the power is from your generator. If it is an inverter generator then this is not necessary. Hope this helps.

Yes . This is a good charger. You shouldnt have any trouble with it running a constant 55 amps

The 12V charger on this unit is minimal, maybe 10 watts, it should say in the specs, but I don't remember. I know I used the 12V plug on my motor home start battery and it barely made a difference on a 600 watt battery. You could use a separate 12V charger as long as it doesn't demand too many watts. Good luck.

This is only a trickle charger, 16Watts under bright sunlight. Not knowing your cooling system wattage it is hard to answer. If the cooling system uses any kind of motor or compressor I doubt it will be enough.

I wouldn't use this charger for a battery that size. It would probably take at least 24hrs to charge it. I would look for a charger that's at around a 2-5amp charger. This would be a good alternative for just a little increase in price.... Schumacher XM1-5 1.5 Amp Fully Automatic Power Charger and Maintainer

You are not likely to have a 2,400W charger (20A*120V), so you likely have a charger that has a total of 20A (12V*20A=240W, ~2A@120V) or a charger that has three 20A outputs (12V*20A*3=720W, ~6A@120V). So, either way you should be fine with this as it is rated to 15A. If you need more reassurance, check the rated input current on the charger itself.
