Review on 🔌 KRIËGER 1100W 12V Power Inverter with Dual 110V AC Outlets, Installation Kit Included, Automotive Backup Power Supply for Blenders, Vacuums, Power Tools - MET Approved by UL and CSA by Justin Abreu

There are 2 main types of inverters in this category of inverters. Sine wave (pure etc.) or modified sine wave. The sine wave produces an output very similar to what you would get from your house wall. Most devices have no problem with this, although you should always check this. The second type is a MODIFIED sine wave. They don't generate energy in the same way as your home. They produce less refined performance to keep the price down. Which one you should choose depends on what you're feeding. You should always check this as some effects appear over time and cannot be seen in a 5 minute test. The general rule is that the more complex and sensitive the electronics, the worse they perform with MODIFIED sine wave power. Think of it this way: if you drive a car with stop sign wheels, it will drive on sand (it will be a heater), but if you drive on concrete, it will be very bumpy (it will be sensitive equipment). There is no universal answer to good or not good. Heaters don't matter at all. Engine life may be shortened (depending on engine type), laser printers, lights, clocks, etc. may not work properly. This inverter seemed to work fine. We may not be able to use it due to possible problems with the hardware it runs on. I only tested it for 2 days but it put out 1240 watts, about 102 amps at 12 VDC. The wattage and battery metrics are useful. The cables are of decent length and construction. With no load, it draws about 0.031A when the rear power switch is on and 0.357A when the front switch is on. Waveform image included.
