2000W Power Inverter

For under $200 this unit was able to power up and run my mini-freezer with no problems. The unit was quiet and easy to hook up. The LCD read out was also useful to see the power loads and status of the unit. I did not see a ground connection to the unit but not sure how that would work using an attached car battery for the power source. Basically, I was looking for a device to power our home mini-freezer and our main refrigerator from my EV during a power outage. The mini-freezer only draws about 60 watts when running but the startup surge apparently may exceed 1000 watts. A previously purchased 500 watt unit (another vendor) was not able to handle the freezer's start up surge but this 2000 watt unit had no problem. I was able to run the mini-freezer for several hours with no problem. I had to set my EV into a "Utility Mode" to allow it to draw power from the main drive batteries via the 12V accessory battery. This device presumably provides pure sine wave output. I don't think the freezer would work properly with a modified sine wave output. The battery cables were substantial enough to handle the power loads. A bit more effort is required to connect the cables to the battery screw terminals but this seems to provide a more secure connection than clip-on connectors that you might find for standard battery jumper cables.

I purchased this 1500 watt modified sine wave inverter for my solar generator build. It is a compact size inverter, and fits well within my system. This inverter has a remote control on/off system (Free with this purchase), which is attached to a phone line. It has three sockets, two USB ports and a cigarette lighter port. Positives: it is a modified sine inverter that peaks at 3,000 watts. It has an easy view display which shows battery life and power gauge. It has a remote unit which only has, on/off function. It appears to be well made and it is compact. It has 3 sockets 2 USB ports. Functions well at this time. It is reasonably priced for a modified sign wave inverter. This is a well made inverter with high quality cables. I have purchased several of these. Negatives: Does not come with a USB-C input. No other issues noted.

This is a review of the 1500W version (6.2A). I work out of a vehicle primarily and have a laptop onboard with a touchscreen monitor & keyboard that's mounted in the cab. This inverter wires directly to the battery terminals, which can be tricky for most people. Hooking it up is the easy part, but running the cabling can be quite tricky (if you're going to do a more permanent installation, you'd run it through the firewall with longer cables - just make sure they're the 4 gauge). Luckily, the vehicle I operate has the battery in the trunk, so I've got the inverter velcro'd in the trunk & cables attached to the battery posts. I then use a heavy-duty extension cable that's snaked in under the side panels up to the front where I've got the monitor plugged in. In the trunk, I've got a power strip hooked into the inverter that has the laptop plugged in & the extension cable. So, ultimately, with all of that powered, I use about 28-29W of power consumption according to the screen. That's... incredibly low for what I'm running. Very impressive. That's with the computer running fully, plugged in, monitor on, with applications in usage. If you're going to run something similar like I have, invest in the additional (sold separately) on/off remote switch. It's what plugs into that little phone-cable looking port, and then you'll run that where it's easily accessible, giving you the ability to turn it off remotely. It's incredibly useful. With my situation, I'd have to pop the trunk to turn off the inverter manually. When I'm on a site, generally I'll power down my vehicle when I'm outside of the car, so I'll hit the switch and then when I get back, I'll power it back on right quick to do some computer work. Previously used a cheaper $30 inverter on Amazon that was around 300W, but quickly found out that it didn't have the protection nor fuses, and lasted only one month of the rigorous usage I put them through as I'm constantly on the computer in the vehicle. The thing I like the most about this inverter is that it's a direct battery terminal post hookup. It's not a socket you're plugging the inverter into just to have a fuse blow for the outlet - not good! There's a ton of applications and usages people will use these for. I primarily see them used in work vehicles, especially vans that's running internal equipment (locksmiths, maintenance vehicles, contractors, etc etc). Recommended.

I didn't buy this inverter for it's quality, it is all plastic and very light, i bought it because i wanted to open it up and immediately get to modifying it for my special application. The body is plastic with exception of the bottom cover, the unit is small enough and it weighs much less than one may expect. Modifying the guts to accept a higher input voltage range is straight forward. This unit is built with single sided and some double sided circuits, it has few integrated circuits. The system consists of 3 nearly independent circuits. The display board contains an STM8S003K3 microcontroller, it calculates the power and measures the voltages to display on the LEDs, it also monitors the remote input, power button and enable the USB 5V buck circuit. The Low side control board is on or off only, it turns on when the display board provides it with power which is simply a switch on the input voltage to the unit. The Low side control board decides if the unit can operate or not and makes the buzzer sound for too low or too high input voltages. Finally the high side control board generate the 120 AC output, it has limited feedback to the microcontroller, there is optical isolation for output voltage and possibly current (two isolators) i didn't bother reverse engineering any of the high side output or feedback as that was not necessary for my task. This unit has a thermal sensor and claims to be short circuit protected. I did not test the short circuit protection as I've had to replace power FETs before in other units which also claimed to be short protected. 4 stars because it did not come with a remote and (before i modified it) i tested it and found that LUP and OUP error codes are swapped in the programming. Maximum input voltage before modification was 15.4x VDC at 25C for my unit. I would expect many 10s of mV of variation across other units. At 15.50V it definitely had issues starting up. photo of the guts attached

Updated 6/16/22 Another year and still no problems. I have it connected to two Group 27 RV batteries in parallel. Have been to Yosemite and many sites in SoCal with no hookups and this is still doing the job. I discovered another appliance that doesn't like square wave AC. It's a travel size hair dryer with an AC-DC converter built into it. The converter buzzes when plugged in even if the hair dryer is switched off. Updated 6/7/21 Bought July 2019 for my Class C RV. Have camped about 60 dates since then with no issues. This runs the coffee maker, the RV microwave, the DVD/TV combo, laptop, and cell phone charger. The only appliance so far that doesn't seem to like the modified sine wave is the Waterpik water flosser. Its motor does not sound as powerful as it does plugged in at home although it still works. Some reviewers complain about the lack of cables but they didn't look hard enough. The box has what amounts to a false bottom beneath which is a bag containing the cables. There is also a small instruction booklet that explains what happens if you try to draw too many amps out of your storage battery before recharging it. If the battery voltage drops too low then the inverter starts beeping. Keep on drawing and it soon cuts out altogether to save your battery from a ruinous discharge. The remote control switch (sold separately) is very handy in my RV. I keep the inverter and battery in the utility bay and turn it on and off from inside the RV. My battery is always being recharged by a solar panel on the RV roof, even when underway, so there is usually enough AC to run the coffee maker and TV/DVD combo at camp sites with no hookups or restrictive generator hours.

I regret not buying this sooner works well I genuinely appreciate the fan power is fantastic I use this alot having a 3prong in the car is a next level luxury I now can't live without it is on the larger size so make sure you have a good place to put it or there will be a mess

I purchased the Ampeak 2000 watt inverter and remote. This inverter had a design issue that forced me to return it as I felt it would be unsafe to leave installed in my RV due to the standard wiring conventions not being followed on all 3 plugs. Detailed explanation below and in video. In my case I was trying to wire it into my RV so that I could easily flip a switch and feed the inverter into two different circuits. One was for the auxiliary outlets so I could use a coffee maker with it. The other circuit was for the microwave. The inverter seemed to work fine when I bench tested it so I installed it in the RV and wired up 3-way switches so I could switch back and forth between shore power and the inverter. First circuit went fine and everything worked but when I installed the second circuit I got an OOP indication for an overload condition. Thinking I had wired something wrong I went back through all of my wiring and everything seemed to be fine until I plugged in both circuits to the inverter and it would cause the hot and neutral to be shorted together. Further investigation found that two of the plugs on the inverter have the hot and neutral swapped from normal convention. Now this isn't something most people would notice if they had individual appliances connected. In my case going through the circuit breaker panel it ties the neutral and hot together since the neutrals are all tied together in the panel. Being a retired electrical engineer I figured I could just pull the front panel and swap the leads on the plugs but what I found was the plugs were soldered into a circuit board so there is no way to swap them and also leads me to believe they are all wired that way which could be a safety hazard or cause a failure like I experienced. I also contacted their customer support and the phone number listed on the website was out of order. I did get a response from an email and while it contained a lot of nice words about how they were there to help they wanted videos to show the inverter working and not working to pass on to their technical staff. I sent them that along with the explanation of what was wrong. Their "technical staff" still couldn't understand it so asked for an additional video showing something different. At that point I was done with their stall tactics of asking for meaningless videos so I decided to return the inverter. While I could make this inverter work by changing my wiring to match their incorrect layout I don't want electronics in my RV where the design has a blatant flaw like this and the technical staff can't understand what is wrong or catch it in the first place. Their last email did say to return the product but nothing about a replacement so I will be ordering a different brand of inverter. I read a lot of reviews but very seldom write one. This time I feel the need to warn people about a design flaw or at least give others the reason they would see the same problem I had. If you watch the video it will fully explain what the problem is.

Great inverter so far. You get in a big box but the only thing inside is the inverter and the cables for instalation. The cables are good cables but not really long, so you might want to use your own cables as I did. I used 2 gauge wires I got from autozone. Dies but fine with a remote so you have to order seperate witch I didn't know and not sure which remote goes with it but I'm sure it says it somewhere in descriptions. It has power and it keeps going. Mine has been on for 24 hours tuning nu lights and TV and I only turned my car on once but I do have an auxiliary battery. It doesn't shut off or the alarm go off for no reason like some other inverters. The microwave does make a weird sound when you run it but it works and heats up your food. This unit reads your battery really accurate. It reads the dane thing my battery monitor says. I still ned to permanently install it somewhere but I recommend this inverter.
