Review on Wagan EL3808 Pure Line 2000W Power Inverter: Efficient DC 12V to 110V AC Car Inverter, ETL Certified for Optimal Performance by Daryle Grove

This inverter has been proven to meet manufacturer specifications. I hooked it up to a 170Ah, 12V lithium battery and was able to easily increase the power to 2kW by using the microwave, fridge and heat gun simultaneously for 10 minutes. I also hooked it up to my caravan and it easily turned on the AC. I was very surprised as my AC needs a little over 3kW to start but then steadily drops to around 1.9kW. Of course the inverter is said to be able to withstand 4kW surges, but I was skeptical that it could withstand even a 3kW surge after seeing all the complaints about inverters from other manufacturers. I left the AC on for half an hour in 39 degrees and the inverter fans came on but it just purred with no complaints. It seems very durable and well built. I definitely recommend this WAGAN inverter - even for the $438 price I paid. It's worth the peace.
