The CPAP requires 15 amp 115 volt power to operate. I wired the inverter to a single dedicated outlet so I can plug my CPAP machine in at night when I'm without shore power.. The power supply in my camper consists of 4 Interstate 6V 225AH deep cycle batteries wired in series/parallel circuit. In total that provides 450 AH which is way more than I actually need for the CPAP machine for one night. When needed I use a 2000 W portable generator to recharge the battery bank. The VertaMax inverter works perfectly for this. I have also used this to power my drip coffee maker a couple of times - great inverter. I highly recommend this inverter for this type of application. Installation was simple and does not require an electrical engineer to set it up. Connect positive and negative wires to batteries and plug in whatever AC device you want to operate to the inverter's convenient outlets (3 ea). ### ⭐ Dead after 5 minutes. *by M***. on December 9, 2023* I've worked with AC and DC for 40 years so I know what I'm doing. Hooked this up and it worked for about 3 minutes. Then beeped and died. Checked battery voltage and it was never lower than 12.5 while the inverter was running. After it died checked for battery voltage at the inverter to test the fuse and voltage was good. Turned it off and on a couple of times. Once it worked and then died again. Fan never came on so not a temp. issue. Returning. Garbage. Don't buy. Edit: after about 30 minute it started working again. Have to assume it's a cooling issue. Was able to use it at about 600watts output (according to its OWN readout) for 10 minutes and then it died again. Went back to Amazon and have ordered an inverter from Vevor instead. ### ⭐⭐⭐⭐⭐ so far so good no beeps or alarms coming on from the inverter ... *by M***Y on September 30, 2017* It seems to be well made the comments are a but scary for being so low but i gave them a shot and I think I did the right thing but time will tell, so far so good no beeps or alarms coming on from the inverter even with a low voltage battery. I have two 100 ah battery with a 100 watt solar panel but by the morning my battery is down to 11.8 volt so when I brew my morning coffee when we dry camp.it does drop to 11.1 and it's sitting there until the coffee has brewed, and then it goes back up to 11.8.So I can definitely say that it's worth every penny.The only suggestion I would make to buy better cables the one's the inverter come's with it's not that bad but they are definitely not 2AWG cause I had to order a longer cable for the positive end since it wasn't reaching my battery so I ordered a 3 feet 2 AWG copper Marine cable by Camco the best cable ever.and it is noticeably thicker then the windy nation 2 awg cable so other then that it is a good Inverter.I would definitely recommend it. ## Frequently Bought Together - 500 W Modified Sine Wave Inverter with Accessories - Sanuke 10pcs 1/0 AWG-3/8 Battery Lugs, UL Listed Heavy Duty Wire Lugs Ring Terminal 0 Guage terminals Battery Cable Ends/Terminal Connectors with 3:1 Heat Shrink Tubing - SELTERM 10pcs - 1/0 Awg - 5/16" Stud - Battery Lugs - Ring Terminal Connectors | with 12pcs 3:1 Black & Red Heat Shrink Tubing with Adhesive | Heavy Duty Battery Cable Ends - Bare Copper Wire Lugs Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/733448378-500-w-modified-sine-wave-inverter-with-accessories](https://www.desertcart.be/products/733448378-500-w-modified-sine-wave-inverter-with-accessories) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-19*
