Used as part of backup system for sump pump.

Giving this 4 stars as I've only had it for a few days.
I bought this to connect to a couple deep cycle batteries for a DIY sump pump battery backup solution.
I have a water sensor which will tell me when my main pump (on the grid) fails. I need the secondary pump to run for a few hours allowing me enough time to get to the house to deal with the problem, or have a family member get there.
If the power is still on then we simply plug the secondary pump into the wall outlet and let it run. If the power went out then I hope to god that the power is restored before my batteries are drained.

I have two sump pumps.
1/3hp Zoeller - Primary pump
1/3hp Liberty - Backup pump (this one lists having lower power requirements than the zoeller)

I don't have the Libery pump plumbed in yet so I tested my setup using the Zoeller.

For the test I have the Zoeller plugged into the Ampeak 2000W power inverter. The Ampeak was connected to a 105ah deep cycle Exide marine battery.
The battery had been charged using a Noco Genius 7200 charger. The Noco charger remained plugged into the batter during the test run.

My sump is currently running for about 4-6 seconds with a 40 second pause between pumps. I let the test run for about 90 minutes.
No issues!
The Ampeak would show about an 850W load initially which would fall to about 800W after a couple seconds of pumping. This was measured using the display on the Ampeak.

This inverter was easily able to go from no load, to near 1kw of load without issue and do this repeatedly for about 90 minutes.

I bought this inverter for one purpose. To facilitate my sump pump battery backup. It has easily done that.

A few notes.
- I have not done any real stress testing to take this inverter close to it's 2000W rating. So I can't speak to that.
- The display only has space for 3 digits, so what happens when you get over a 999 watt load???
- This unit is plastic. It's in my basement in my utility room which tends to stay fairly cold so I'm not terribly concerned about temp. It will also only run when my main sump pump fails which obviously doesn't happen often.
- The front fan runs all the time.
- The rear fans seem to kick on based on load. Right when the sump starts to run the rear fans spin up. I have a hard time believing they're temperature based when they kick on with 1-2 seconds of the sump starting.
- The display is nice. It show you the Volts as well as the Wattage load.
- Included cables are nice, 2/0 AWG and they easily reach my batteries with length to spare. I didn't measure them but I think they're 24 inches each.
- I have not stuck a multimeter on on the battery to verify the Volt reading on the inverter is correct.
- The inverter comes with plastic covers for the terminal connections. A small thing, but a nice feature to keep the terminals from being completely exposed.

I have no regrets with this purchase at all! Then again, my use case is very specific and this Ampeak inverter seems to solve my problem with ease.

If you have a different use case you may not be as pleased as I am ( or maybe you'll be more pleased??).

I am a retired electrical engineer who used to design similar products. I chose this one for its high power rating and reliability. I tested it using a car-battery charger as an input power source. It converts your car's battery voltage to an AC Voltage, 110V/60Hz, the same as the power outlets in your house (US). This device enables you to operate appliances that run off of the power from your wall outlet using just your car's battery voltage. It is great for camping or during a power outage. I keep it in the trunk of my car. I am considering buying another to keep in my wife's car as well. Very nice product, well designed.

This is a review for the 1,000 Watt version. However, it should essentially be the same as the 2,000 Watt one.

Pros:
- Good built quality. The main body is made of aluminum and the "end caps" are made of rough dark plastic,
- Although the inverter is relatively big (see attached image for size comparison with a quarter), it's actually not heavy at all at around 3 pounds (1.4 Kg).
- Embedded screen showing input/output data
- Included USB type A port.
- Safety features such as: short circuit protection, overload protection, low and high voltage protection as well as overheat protection (really useful in the summer).
- Shielded terminals (ends connecting to the inverter).
- Ventilation fan is relatively quiet.

Cons:
- At this price range, it should include the alligator clips for easily connecting to the car's battery. Not a big deal, as this clips can be found pretty cheap on Amazon these days (less than ten dollars).
- USB port can only deliver 2.1 Amp (2.4 would be idea for charging tablets and large screen size electronics).

All in all, a solid device.

We recently picked up a new project car that we've been restoring and I was wanting to add an additional distribution off the battery terminal to connect to an inverter. This couldn't have been simpler. I tested with the supplied leads for functionality though we intend long term to connect it to a longer clasp cable diverted from the battery terminal splitter. This fits perfectly in the glove box or trunk if you're thinking about an internal placement more permanently fixed location.

So for the testing I was able to go direct to the battery and ran a voltage test for just a bit over an hour and was getting good consistent draw throughout which was impressive.

If you're needing a higher watt inverter for your car or rv this was a great product for the price point.

This is nice sized portable inverter which can draw up plenty of power for a variety of scenarios. This summer, I am looking forward to using this for music, television, and LED lights. One side of the unit contains a USB port and three outlets. The other side contains battery connectors.
