Kundeanmeldelser for VEVOR strømomformer modifisert sinusbølgeomformer 5000W DC 12V til AC 110V LCD

I am an electronics engineer. This product is defective or a scam. Tested with a 300A LiFePO4 battery. It does not provide even 1600W on the claimed 2500W. They have a Watt meter on the unit that gives a false reading (I tested with a resistive load to make sure the reading should to be correct). It is possible they falsified the meter reading to give you a false impression that you are using the unit to its fullest potential. So when you connect a 1500W load it tells you you are at the limit of 2500Watts, this way you do not put anymore load and discover that the unit can't even deliver the claimed power. See pictures, my Watt meter has been tested and I know it is correct. My Watt meter reads 633W, the unit says 1138W. At 725W it reads 1304W. At 1317W it reads 2362W.

Bad build, cheap materials, poor customer service, AVOID!

I can’t get this to work. Can I get another one to replace it ………………………………………………………………………………………………….

J’aurai bien aimé évaluer mais j n’ai jamais reçu l’article

I purchased this large inverter for my RV, to run a Harbor Freight Electric Log Splitter while camping. Splitter is a 120V 15A rated. Unknown in-rush current or duration. Thought this Inverter would be overkill, but not so. I connected inverter to battery back with 2-0 heavy battery cable, 3 ft long. Plugged in the Splitter and hit the on button. Inverter went into overload. : ( Gunna talk with my local electric motor guy and see what I can do to slow down the in rush current. The splitter works fine on any 15A outlet in my house.

Mi conversor está dañado, lo conecto justo dice la indicación y no encendió; luego abrí la tapa y vi que estaba con una mancha en la tarjeta una mancha de quemado.

Junk

I NEVER RECEIVED EITHER OF THESE PURCHASES (POWER INVERTERS)...I NEVER RECEIVED REVERSE CHARGES BACK TO MY BANK ACCOUNT ($465.74) ... WHY DID ESTHER (CUSTOMER SERVICE REP) CLOSE THIS CASE BEFORE I RECEIVED MY CHECKING ACCOUNT STATEMENT ??? Why has nobody called me or texted me on this situation??? I'm NOT happy about this....

Plugged in for the first time and didn't work.

I purchased this product on April 29 2025. This product is garbage, it doesn't meet my needs to run a microwave. So I requested a refund and now vevor will not refund my money, they offered me 36.00 to just keep it and not return it , there is no point in me keeping something that doesn't work, wtf?
