I haven't had the opportunity to use my power inverter, yet. I store it in my mini RV/conversion van. It gives me so much peace of mind to know that I can power my CPAP if I can't find a plug in.
Great for charging or powering devices that do not consume much power such as a laptop computer or, in my case, an electronic balance. You can plug the inverter directly into your 12V outlet. The unit has no fan, which means less noise and current draw. Great small size. However, the 12 V plug is too stiff in my opinion.
I bought the 150W PowerVerter Ultra-Compact Car Inverter to run my CPAP (breathing machine) while I am camping, and in case our power goes out at the house. It works perfectly for my needs. Other inverters that I've used are larger, bulkier and also have a noisy fan that runs whenever they were connected and turned on. This inverter is very compact and runs silently (no fan). My CPAP is rated at 90W so the inverter has plenty of power for what I need.
