BESTEK 300Watt Pure Sine Wave Power Inverter [30W PD USB-C] Car Adapter DC 12V to AC 110V with QC3.0 USB Ports, Multi-Protection Car Charger Power Inverter for Vehicles

I go camping and need a portable bi-pap machine.After trying several this one actually runs the machine. Apparently the others I tried they're not put out a pure enough sine wave. This one works perfectly..

When I initially tested this inverter, I found that it was only able to deliver 150W of AC power before it cut out. I mistakenly thought that this was because the unit was limited to just 150W of pure sine output.However, after communicating with the BESTEK customer service team, they explained that the limitation was due to my vehicle's 12V DC accessory outlet not being able to deliver enough current to allow the inverter to function at its maximum rated output. Once I retested the unit with a direct connection to the car battery, I found that it could easily deliver the rated 300W of AC output.NOTE: Although the unit can produce 300W of output, because many vehicle 12V ports are rated for only 120W - 180W, if you need higher levels of AC output, you may need an adapter that allows you to connect the inverter's 12V plug directly to the car's battery with clamps.

The inverter produces a clean sine wave, not the low quality ones that jump the voltage up and down, using a minimum of 50 watts to power any AC port. BESTEK makes great products. I still have a car jumper battery from them that they stopped making years ago, and it can still jump start my car to this day. Great quality that lasts.

Used during a recent road trip for phones and laptop charging. It worked better than others I've used and did not shutdown periodically like others. It's also pretty quiet and didn't notice if it was excessively hot. I don't love the way it looks but just kick it under the seat and problem solved.

Meets my charging needs on the go

never worked.

It provides consistent power, perfect for sensitive electronics and appliances. The build quality is solid, and the inverter is compact and easy to install. I've used it on road trips and during power outages, and it performs flawlessly every time. The multiple outlets are a bonus, making it versatile for various needs. Highly recommended for anyone needing reliable power on the go or in emergencies!

Nice inverter. Great finish. Looks and works great. Quiet during operation. Runs warm but not excessively high. Been in operation for three weeks no problems. I would recommend it
