BESTEK 300W Pure Sine Wave Power Inverter - DC 12V to 110V AC Car Converter Plug Adapter Outlet with PD30W USB-C Fast Charger - Vehicle Cigarette Lighter Adapter for Laptop

I use this on my boat, docked and off shoe, to power my internet service and auxiliary router. Power use is very low and essentially uses my 2 4D house batteries, which keeps everything going if there is a power outage when docked. No problems. Interestingly I boat the 400 watt model and discovered it was discontinued. I bought this 300 watt as I didn’t want something that had been dc’d on my boat and wrote that in my review. Late was contacted my the manufacturer asking if I wanted a refund which I accepted. They got my attention and will have my business

I bought this for road trips specifically to power my 130W gaming laptop for work. The standout feature is that this is a Pure Sine Wave inverter. Unlike cheaper modified sine wave units that often cause laptop bricks to buzz or cut off entirely, this provided clean, stable power in my car. My laptop stayed at full performance without any thermal or power-delivery issues. Perfect for sensitive electronics or a high current draw laptops.

Portable power for laptops and other devices is easier than ever. I always keep this in the trunk of my car now in case I'm out someplace and need some extra power. Runs cool and quiet and the cable can reach to the back seat of passenger cars).

I've been able to power a fan and my laptop while out dry camping without breaking the bank. It just works.

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!

Works great, Fan dosen't stay on all the time like some. Cool looking. Would be good to have a wired in connector, had to cut.

Works perfectly. Used it for craft show lighting. Hook it to a deep cycle battery and you'll have power all day. Quiet too. Didn't seem to use up much power to run.

Unit as described and quiet. Using as an additional outlet for a portable battery box. USB, USB-C and two 110V AC plugs all worked and powered items. For those making battery boxes: Attempted to use it with my 20V DeWalt Drill Battery directly connected into a cigarette lighter female plug but it would not energize. Stepped my battery down to 12 Volts and no problem. Works flawlessly at 12 Volts (as expected).
