> 3 dayGot this last May for my camper. Worked great until last week when the voltage regulator went out. I called the company and they shipped me a new one in 3 days.

> 3 dayGood power supply for ECU programming. Holds constant voltage during ECU module programming. Auto shut off if another power source is detected. Charged fully drained battery under 45 mins. Only con in this power supply is that it doesnt have power supply voltage reading measure display, you have to use volt meter to determine the measurement under fixed voltage supply. If you are programming BMW ECUs I recommend you set the fixed voltage to 14.2 vdc so your output value on terminal 15 and terminal 30 remains between 13.6 to 14 vdc. Voltage supply only fluctuates for the first few mins.

Greater than one weekI replaced my RV converter with this, i expected it to be a temporary measure but its held up fine. Ive got 300 watts of solar panels so it doesnt generally have to do a lot of work but im still impressed it has lasted so long.

> 3 dayAlthough this product lasted me about four years, can anyone explain how it burned up these two 40 amp fuses all of the sudden out of the blue? It operated flawlessly all this time and then the fuses actually melted and also melted the fuse sockets. At the time of failure it was powered with a 1,600 watt Predator generator - that has also ran many many hours flawlessly before and after these fuses burned up. Since the fuse sockets melted I am not going to replace the fuses just to see what might happen. Thoughts?
