There are 2 main types of power inverters in this catagory of inverter. Sine wave (pure etc.) or modified sine wave. Sine wave produce power very similar to what you would get out of your wall house hold power. Most devices don’t have any issues with this although you should always check. The second type is MODIFIED sine wave. These do not create power the same as your house. They produce a less refined power in order to reduce the price. Which to choose depends on what you are powering. You should always check because some affects happen over time and wouldn’t be noticed in a 5 minute test. A general rule is that the more complicated and sensitive the electronics the worse it will do on MODIFIED sine wave power. Think of it this way, if you drove a car with stop sign shaped wheels it would do ok on sand (this would be a heater) but if you drove on concrete it would be very bumpy (this would be sensitive equipment).
There is no universal answer for ok or not ok. Heaters generally don’t care. Motors may have their life reduced (depending on type of motor), laser printers, lights, clocks etc. may not work well.
This inverter seemed to do well. We may not end up using it do to potential issues with the equipment running off it. I’ve only tested it for 2 days, but it delivered 1240 watts, around 102 amps at 12 VDC. The watt and battery readings are useful. The cables are a decent length and construction. With no load it draws around 0.031 amps with power switch in back on, 0.357amps with the front switch on. Included a picture of the wave form.
