Is this charger power-efficient? Does it produce a 12VDC supply and use linear regulators to go down to 1.5V, thereby burning 3/4 of the power?

gave this as christmas gift they have not used it sorry can't help it nice looking but looks lot like the older style

The charge output is very dependent on your charger & cable. I get anywhere from 400mA to 1900mA using my old chargers and old cables. I do own 3 of these cradles because they are very good.

John,California just passed a law that requires manufactures of battery chargers to be more energy efficient. They are saying battery chargers take too much electricityy to run them. Some manufacturers are beginning to re-tool so they can comply. However this is a double edged sword. Consumers in California will most likely pay more for the chargers than what they will save in electricity use in a years time.Joe

No, this is not a charger, it reduces the voltage from a 48 volt battery pack to 12 volts so that 12 volt accessories use all the batteries equally.

No. The solar charger is expecting a solar panel. A solar panel in sunlight puts out much more than 12 volts and the charger will regulate that down to provide the optimum power delivery to the battery. A 12V 3A supply won't put out enough voltage to charge the battery even if it was connected directly.

As I found similarly with the design of their car adapter, which showed negligible draw on the car battery when plugged in by itself, testing this charger also exhibited no significant power draw on the AC line when not actively charging.Because it doesn't even use an LED indicator to display that it's on, which almost every other device in the world uses, it's quite efficient and can be simply be left plugged in without any concern for wasting energy.

I would think not, this is just a slow trickle charger. You are looking for a 12v continuous power supply.

Yes to both questions. I bought a higher amperage battery to use as my primary power source. The charger works well, even when I took it overseas.

This is acute little charger. It says the maximum current output is 500 ma. That's probably at 6 volts which means the max at 12volts will be about 250 ma. Not really powerful but if you are not in a hurry and you have small lead acid batteries this works well. Hope this helps.

This charger is capable of charging 6volt and 12volt batteries. The "start" option for 6volt is 100amps whereas it is 200amps for 12volt. Yes, there is a 100amps option but at an output of 6volts.

This is a charger not a battery. However it will supply a steady state 13.5 VDC at 5 amps. It will supply that voltage indefinitely.

NOTE: 1 watt at 12vdc means this only produces 1/12 amp. This is a "micro" trickle charger. Look at plug in trickle chargers on Amazon-- they range from 1/2 amp to 1.5 amps. So it will maintain a battery lead acid if it is small and is not operating too many systems such as car clocks, on-board computers, etc. 1/12 amp for 12 hours is only 1-amp-hr. So if your battery has a 100 amp hour capacity, it will take several hundred hours to charge it accounting for parasitic losses and changing battery voltage.

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.

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..

This charger has a voltage readout so you can observe that it doesn't maintain a constant (float) voltage. It seems to let the battery drop to a predetermined level and than recharge (energy conservation?).

No. It has a proprietary DIN connector from the power supply to the charger main unit so no way to power the charger with common coaxial DC power connectors. Unless you use an inverter to make 115V AC power and plug the charger power supply into the inverter. Not very efficient though.

This is a manual charger, I have used it on all most dead batteries, it should also work on those completely dead. Automatic chargers will not. As to the use as a power supply, I have not tried that, but my knowledge of electronics tells me, it will supply the voltage and current, the voltage will be unregulated and unfiltered.
