Anyone have some info on why you can pick up a China 30 Amp charger for $ 190, and a name brand charger in Auz will cost around the $700 mark. (there are other 30A chargers for aroundt the same price, so it is not unique)
I have two of this same charger, 1 kept permanent in the tug and the other permanent in the garage.
Had them for a few years now and cannot fault them
Near same pricing -- $35 for the first and $41 for the second
Cheers
Vince

Great thanks,
We wont use it often, just when there hasnt been good solar for a while and the batteries are getting low, then I want to get the max amps from a few hours of generator.
Nice to know you guys are using em with no drama's thanks.
Nice charger Col, I also like the remote sender, need to look at the most cost effective though and $ 180 for 30 Amps is the best i can find at the moment.
Great price there Hako, may look at that as an alternative to the 30.

My take on this, all battery chargers are not created equal, even some so called "Smart chargers" are not too smart and can drop back into absorption mode as soon as minor load is applied on the battery, causing it to eventually boil and or swell. Been there, done that !
A base type charger as shown (no mention of 3-4-5 stage smart charging) will have to be monitored closely so that it does not boil the battery and kill it !
AGM batteries are expensive now, why cut corners and chance destroying you expensive batteries ?
I have seen scope traces of AC ripple on the DC charger outputs on some cheap chargers that will eventually kill a battery, why take the risk to save a few dollars, buy a quality unit like CteK or Projecta and look after your battery, it will thank you for it by living longer, and be possibly cheaper in the long run.

The OP is only planning on using the charger to "push amps back into the batteries quickly when we need it." so in theory any old charger will do the job. If it was going to be connected constantly then banjo's advice would be the way to go as long as you have the cash IMHO.

Any ideas on what makes them different and justifies the price?
Budget is tight and im looking for a 30 Amp charger so that the Gennie can push amps back into the batteries quickly when we need it.

I bought one of these which is a 20 amp model:

and have found it to work very well. It has a cooling fan that runs till the charge rate drops to about 5amps. Probably not as sophisticated as the ones costing 20 times as much but they both do the same job. I tested mine on an almost flat 105 amp hour battery and it pumped out 20 amps or just under then slowly dropped to a trickle after a few hours.
Best thing is the price...$39.
Good Luck.

They also have a 40amp model:
