«  unbeatable for the price. »

The first thing to note is that it is increasingly difficult to find it. I found that in Amazon or U.S. sites. I took to change my power plant in harley benton, that even if the price is his office does not have isolated outputs. Here is the case, it can be placed in 220 or 115v if you travel around the world with its hardware, it's nice. You can also emulate a battery end of life on two outputs from 9 to 4 volts if it is equipped with a small screwdriver. We also have the right to Ac output and can pass other 12v (from memory, because I do not use it).

The value for money is unbeatable, I recommend it to everyone instead of typing more expensive fuel tank and with fewer options.
