Maybe good for something but wasn’t good for me
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was unable to use this. I only needed it to plug my laptop in while in the car. It couldn’t handle my laptop and alarmed very loudly. When the alarm finally stopped it smelled so bad I unplugged it.

12V Adaptor Plug is too large for cigarette port
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The device works, but the plug-in to use it with your vehicle's 12V "cigarette" port is too wide and long -- it can be used but the slightest bump or wiggle will cause it to fall out, or it will gradually come out over time. Whenever it does, the device beeps really obnoxiously loud for losing power. It is not just a problem with my car -- i checked it in 3 ports in an SUV and 1 port in a Sedan; same issue in all. Unreliable and would not recommend this.

Cobra
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Worked first time every time. Used it in an RV conversion for several different appliances with one car battery as the power source. Worked well with one appliance or lights and charging a phone or other accessory. Our power source depleted quickly and needs to upgrade. Inverter is a good product needing a better power source than I used.

Cobra Power Inverter
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Provides reliable power to operate and charge my laptop when i am in the field and also charges my drone batteries.
I would recommend this to a friend Pretty good purchase
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works pretty good!! The only downside is that the car plug is kinda cheaper so it doesn’t plug in very smoothly, and kinda slips out. I have to press it in really hard and make sure not to move the inverter so that I don’t accidentally move the cable or anything. A little finicky but works great once it’s plugged in properly.
