URVNS 240W USB C Car Charger, Super Fast Charging 4-Ports PD3.1 140W/PD3.0 100W PPS 45W QC65W Type-C Car Adapter for MacBook Pro Laptop iPhone 16 15 Max iPad Samsung Galaxy S24/23 Pixel etc

This car USB charger performs excellently, no problems.

I have to honestly say I'm impressed. From 32% battery life in my Galaxy S24 Ultra it usually takes about 1.5 hours to fully charge my phone. That's not the case with this super fast charger. Within 35 minutes I'm already charged up to 80% because of its power output. Now I must say that I do have it coupled with a 100 watt rated charging cable to ensure no wattage loss during charging

This one works even on unusual devices like my EGO Power+ PAD5000 Nexus Escape 400W Inverter. I tried a couple other USB C power delivery 140 W cigarette lighter outlet adapters, and neither would charge the EGO battery above about 30 watts, if I used the 140 watt USB C port they would stall, but this one works fine on any port. Those other USB C power delivery adapters worked fine at 140 watts with a laptop computer but not the EGO battery charger. This one works with them all. The trick might be that the EGO battery charger can either source power from its USB C power delivery port or accept power, while laptops typically only accept power at 100 W but won't source 100W. This adapter is not confused and works fine.

If that's why you're buying, don't buy. Every 5 seconds the 140w will reconnect and pop up on ur screen.

Works as advertised on 12v.I was able to verify that it puts out 130W on a 12v battery. This thing is great.Works with my Dell laptop as well as a Samsung laptop and a Samsung galaxy phone and an iPhone.

Works very well and charges fast

I wanna preface this by saying that I've only had it for one day so I can't attest to the longevity of the charger. But if it breaks in the near future through no fault of mine I will update this review.So far this thing is great. It's pretty huge which is unfortunate but it performs very well. I'm not able to measure power coming out of it but it seems to be able to charge at its advertised capacity.I tried the following 3 devices with it. A Galaxy Note 20 Ultra, a Steam Deck, and a ThinkPad t490. All 3 charged at normal charging rate. My phone charges at super fast charging so it fills from dead in under an hour. The Steam Deck, which requires 45 watts charges and doesn't lose battery while playing intensive games, and the ThinkPad which requires 65 watts says it's charging normally. If it gets less than 65 watts it says it's slow charging, and below 15 watts it won't charge at all.I was able to plug in all 3 devices at once and they all charged at full draw except for my phone which said it was only regular fast charging instead of super fast charging.

Knub messes up and prevents proper charge.
