Title: My first one lasted years.
Review: This 410 watt inverter is a replacement for the last inverter of the same brand and size I had.I used the previous unit for camping and fishing. It would run a vacuum packer as long as it was connected to the battery using the supplied connectors. It was many years old, I can’t remember where or when I bought it.Lately I was using this inverter to run our tv and internet device full time in our RV trailer. We like to boon dock often, and I have a solar array on our 5th wheel. We do not use much shore power and can be energy independent. This Schumacher XI41B works fine for that use.The failure of the old unit started as excess fan noise. When I checked the output, it was only showing 90 volts AC output, the unit was hot too. I may of hastened it’s demise by not paying attention to the 12 volt power supply wires, ie, too small and too long.When the first unit failed after many years of use, I had no issue with buying another.I since I bought a new inverter, I dedicated a run of 9 feet, 10 gauge wire from the battery to the inverter. The voltage line loss is minimal, as I am only pulling 3.5 amps 12 VDC from the battery. I checked this with a Fluke AmpClamp Volt meter. Very handy device.The TV and 4G modem are all low voltage devices, and do not use much 110 volt. So far the inverter runs quietly with no problems. I have not heard any fan noise, it does get warm, but not hot.To get the full 410 watts would require (410/12=) 34 amps (10 AWG minimum), and a bigger gauge wire would be needed. Since my amps requirement is small I can get away with this size wire to length. I read a lot of misconceptions and complaints about wire size and runs, and then complaints about the device not working right. The battery clamps wire is short for a reason.The 120 volt output is not the best or steady, and is more like 110 volt AC. But for recharging or running low voltage devices, this works fine. Just beware of the limitations of using the smaller plug in 12v connector. For full power, this must be connected with the battery clamps, or use a good gauge wire with appropriate wire length from the battery.

Title: Used for running lights in my remote shed off a battery
Review: Seems OK, does not like it when all the lights are on and in the heat of the summer (fan kicks on ASAP and runs wide open — when that happens its pretty loud. Over all not a bad purchase for the price

Title: Itâs fine when it works, way over rated for power
Review: I have 185w exactly of lights hooked to this. No long wire runs or anything, just 185w. When turning it on, the lights flicker a ton and the unit just says overload and retries over and over again. I can run less lights down to 145w and itâll work fine, but it definitely isnât rated for what it says.Edit: changed it to a 1 star as the problem seems to be getting worse over time. Running less lights now it will trip the overload. Donât buy this.

Title: All the power I need
Review: Powers a small TV/DVD combo and fan, etc in my SUV converted camper. Works great. It it’s hard wired to the the battery and fused as it should be to get full power from the unit

Title: Impractical Voltage Range
Review: This works fine but requires a fully charged battery. Once the voltage begins to drop below 12volts the unit will start complaining and will shut down… The unit also will not operate if the voltage is above 13 volts or so… This makes it tough to use with anything other than a powered vehicle running. The super narrow operational range means you should look elsewhere for a better inverter…

Review: Pre buy info is not good as it does mention one needs to direct hook to battery for all +100W. Also the shut off bleed of 0.8ma was not known until read the manual.
