I purchased this for lights in my shed, I Have this hooked up to a battery charged by a small solar panel and it has been working good. The one it replaced burnt up from the heat, so time and summer heat will tell.

After almost 8 years, this thing has been used and abused, but keeps working like a champ!I've used it for all kinds of random things over the years, both with the 12 volt car port and the clamps for direct battery use. It's even had a few uses running small home appliances for a few days straight with no issues! (TV, console, sound system, and some other odds and ends all at the same time)The low battery protection is great for keeping the cells from being damaged due to running too low a voltage, but I wouldn't depend on it too much if you're using it on your main battery without running the car if that's what you're hooked up to. I forgot to leave the car running in an instance and the low battery indicator cut power as it should have, and when I went to crank the car I was lucky and it barely came to life! (4 cylinder motor, battery midway through its life. Your luck may vary!)I honestly bought it figuring I'd get a better one for small tasks when I got more money and it just refuses to die. I had one issue where I crushed the 12 volt plug and there was some language issue in support, but they were amazing and ended up just sending an entire unit overnight at no cost so I'd have extra of everything. (The inverter had no logo and was on a black shell, but I still have it and feel bad when I use it in conjunction with the main one!)Tldr: It just works and you'll be happy if you don't need crazy power output. I swear they haven't paid me, but I'd shill their products at this point.

Update 9/18 - inverter works well with my 700watt microwave (draws 1100watt) and 1000watt airfryer. Seller sent new Bluetooth adapter for free (excellent support), and it is better. 2 issues 1) the Android app needs to be reset every time before using. - its a hasstle, but there is a workaround 2) I noticed my battery drain when in standby in Bluetooth mode. Its not a huge concern, and I have now started turning off the invertor after use (instead of using Bluetooth standby). Overall, I am happy with the purchase at this price point.Update 6/17 - increased 1 star after testing Invertor under load - tested with 700watt Microwave (which draws 1100watts). Bluetooth is still a bit unreliable and hence 1 star is reduced. Testing completed - I will be using the invertor next week when camping.Update - 6/16 - increased 1 star of review because Tech support reached out and sent a new bluetooth USB adapter which appears to be working better. The App is still has connection issues, but the workaround to connectivity issues is to reset storage or uninstall-reinstall app, and it works. Invertor must be in bluetooth mode - not in ON mode.Next step - I will test the invertor at full power, and then post a update.Original review of 6/14/2022I just bought it few days back - tested it and now installing it.Sharing my initial impression after unboxing and testing- 6/14/2022. Will share updates later.1. The positive - Invertor function works along with auto-matic bypass - have not load tested it.2. The positive - really good value for the features-capabilities.3. Bluetooth is unreliable enough to be a pain- Android app only connects to Invertor in Bluetooth mode, and the app stops connecting and needs to be reinstalled frequently. - the workaround of reinstalling or clearing storage every time it stops connecting is currently working, but not a good sign4. Total Lack of tech support- this is the biggest problem with this product. The US phone number listed in manual is disconnected. No response to email support. The facebook page listed in manual does not exist. - this is a serious problem and I reduced 3 stars due to this.

i use it in my transport truck its a little hard on the batteries but i can't work with out it runs all my electronics

Excellent...been in use for a few months no issues what so ever except forgot to shutoff once and it drained the trucks battery once over a weekend.

ok but not as powerful as I thought it might be but will do the job

Exactly what I have been looking for.Well made......hooked a battery to Inverter with no problems usinglights or certain power equipment.and USB. Proof is in the real emergency....Thanks again

Works really good. Does what we needed it to. Easy install. Only complaint was that the cables were too short but we just bought longer ones.

I was recently seeking a portable power inverter for use in my vehicle as well as my travel trailer for when I go camping. I happened to find the Potek 500W Inverter here and opted to give it a shot based on the price and because it looked like it would get the job done. Of course, there is a 1000W inverter; however, I don’t need anything with that much drag on my battery and am quite satisfied with 500W at this time based on my personal needs.If you’re a camper or need an emergency power supply (110 – 125 VAC) when you’re on the go, then an inverter is what you need. I am not going to pretend that I know enough about electrical connections or currents in order to sell this to you in my review, but what I will do is present it how I intend to use it and have used it and you can decide from there. I haven’t a significant understanding of electrical systems, so I am a bit of a letdown there. However, as a “typical user,” perhaps this will review will help you as it would me!Here are some specs for those interested:Input voltage: 12.8-13.2 volts DC (VDC)Output voltage: 110-125 volts AC (VAC)Output frequency 60Hz +/- 3HzContinuous output power: up to 500 WWaveform: Modified Sine WaveEfficiency (Maximum): 90%Output power overload shutdown: 550+/- 50 WFuses: 30A (x2)2 NEMA AC Receptacles1 USB Port (2.0A)Can connect both to a battery (e.g., vehicle/deep cycle) and via 12V accessory plugOkay, now that specs are out of the way, let’s just talk about how the unit works and how it looks. I love the look of the unit, as I mentioned before, because it appeared like it would get the job done. I like that it looks professional and is not very large. In fact, the unit is smaller than a typical amplifier you would see in a vehicle for an audio system. In addition, the unit has four small notches on each of the bottom corners so that it can be mounted flush against a wall or other setup such as in a vehicle, trailer, etc. I will likely mount mine on a block of wood that is easy to set out with my battery on my trailer and at my vehicle should the need arise to use it.The unit performs very well and is extremely quiet. I’ve owned other inverters that kicked the cooling fan on within 30 seconds of use; however, this unit does not kick the fan on for quite some time, even under decent load (not full). I assume that if I maxed out the output power upon first turning the unit on, it would likely kick the fan on immediately.I love that this unit has two NEMA AC Receptacles, as I can connect my laptop and a mobile phone charger that requires something higher than 2A. For example, I use devices that use Quick Charge, and I need a higher amp charger for that to function, therefore connecting two units to the NEMA ports is convenient. Additionally, I can charge my Bluetooth headset or other lower-amp requiring device using the 1 USB port (2.0 A) (e.g., low-end tablet, Bluetooth Headset, speaker, portable Wi-Fi hotspot, Nintendo DS, etc.).Overall, I wasn’t able to overpower the unit during my use. Although I would not necessarily recommend it, I was able to connect an extension cord into the NEMA port and power an electric drill off of my battery (this is not pictured as I did not have my mobile device with me during that use). This was a great example of how I can use this inverter in a pinch when I am in need of power supply and all I have is a battery. The unit performs well, is quiet, doesn’t get extremely hot, and is easy to hide away in a compartment or under a seat – don’t forget it’s mountable should that be necessary!I am quite pleased with this unit. I have placed it in my vehicle’s trunk at this time so that I can use it in a pinch should I need connected to power without being close to it. I travel for work quite a bit and am on the road constantly, which means I am not always near a power supply that is sufficient for my needs. Therefore, this unit will provide a much-needed connection point when I am on the road for extended periods. Additionally, it will be great for camping as an extra connection or in my shop that is not connected to AC power.If you’re in need of portable power, look no further!
