Wagan EL2600 Elite Pro 200W Pure Sine Inverter

I have been running this unit solid non-stop 8 to 10 hours a day 6 days a week in a work vehicle, it is powering a 90/120 watt HP laptop in high performance power plan mode with a discrete Nvidia graphics card onboard. On the second outlet there is a 35 watt continuous UtiliQuest GPS site survey location device running fulltime also. This 200 watt inverter has not skipped a beat over the past 4 months of continuous field/work use. I have heard the fan ever so slightly only a couple of times, the unit doesn't overheat at all and it is the smallest pure sine wave inverter I could find for my power consumption needs. I know the unit is running at peak efficiency because efficiency increases when an inverter is running at or as close to its rated capacity. I wouldn't hesitate to buy another and this is my first experience with a Wagan product.

Seems to work, but when it senses low voltage it emits a terrible beeping alarm. As most common 12 volt systems will have high amperage components (macerator, engine starter, water pump, bilge pump) the idea that you need to be notified when the voltage drops is kind of dumb. The USB plug was installed a little wonky too so it seems to be a challenge to plug something in. It does work an inverter and I use it mainly to keep my laptop charged because my DC charger failed and I needed a backup. I also don't think it works with 200 watts. I've had the annoying alarm turn on when I tried using an 85 watt laptop charger. It can handle 45 though and I happened to have one that works. Not amazed with this thing but I also have not returned it.

Read the directions first, then plugged it into my truck cigarette.lighter plug. Blew a 15 amp fuse, tried another one, same thing. Hooked it up directly to a spare 12 volt car battery, with a remote cigarette plug. The wires from the battery started getting very hot, I never did get to turn the unit on. It is obvious that this product never got tested before it left the foreign manufactures. This unit has a direct short. I will not waste my time on anther.

Ordered two inverters. They are really pure sine waver inverters with the same AC as household power. Tested them at work with a friends machine that shows the sine wave. Real beautiful sine waves when compared to modified sine waves. Only issue is that one of the inverters Green light was on and it beeped at first when turned on but no power from the outlets. Returned it and received a new inverter really promptly. For some reason it takes a while to power up 74 watts that is plugged into it but starts up quicker with another that requires 100 watts. Maybe the surge load is a little high at first when starting for the 74 watts compared to the 100 watts.

The problem I have with this thing is the fact that it cuts out and chirps while using my laptop. My laptop has a draw of 120 watts MAX, so I thought this being 200 watts I would be OK. However, just moving the mouse, opening and closing windows, causes the inverter to chirp loudly (either under voltage warning or overload warning, I do not know which) and it cuts out for a second, long enough for my laptop to indicate that it went to battery power instead of charging. I have not even tried loading this thing up and doing anything intensive, this was with basic internet browsing. I don't see why I should need a more robust unit for such a small power draw. I have plenty of other inverters that work just fine, but I wanted pure sine wave so I got this, and was quickly disappointed.

I bought this unit to replace another that had a noisy fan and was not pure sine wave. I use it to power my CPAP when primitive camping. It consumes about 105W with the humidifier on. While running my CPAP overnight for about 8 hours, the unit never felt warm. I was able to use a watt hour meter to determine load which would not have functioned without a pure sine wave output. This is a great little inverter that appears to be very efficient. My deep cycle battery dropped from 13.4V to 11.9V after three nights of use.

I initially bought this to run my guitar amp on battery power so I could busk. It worked very well for this and provided nice, clean power without any noise, important for music applications. I later installed it in a van with power and it failed within a month of near-constant use. I speculate that perhaps the 14.4v that was being pushed into it while the batteries charged may have been the cause, or maybe it just wasn't intended for 24/7 use. In any case, it still functions, but with some terrible buzzing noise, and it can no longer handle anywhere near 200 watts.

I don’t like leaving negative reviews and ignored the other negative reviews. This product does not put out as much wattage as advertised. Would not power up a PS4 even when connected directly to a battery. Should have had no problem, since the PS4 only draws about 70w. It was quiet though. I purchased a Bestek inverter and it works great to power both the PS4 and a 32” LED TV.
