Really like that it has a power button, so it doesn’t drain the boat battery. Pretty much the only one that has this feature. Also love that I can monitor my battery voltage, and even see what the power drain is when different items are turned on. Bought 2 more for my other boats!Installed in classic car to plug phone into and it has a volt meterVolt gauge is niceFits perfect on a Kawasaki Ninja 400. Great product.I checked the voltage that was being displayed with a multimeter and it was always spot on, maybe 0.01-.05 V off from time to time. The installation was easy, the wires were thick and seemed durable. I have no complaints.I was able to install in about 20 minutes total including testing and checking the systems before trying it out with my phone. The bulk of time was using a dremel to carefully sand a good snug hole for the socket to be seated properly the locking back ring helps keep the socket on nice and tight. I installed it in my 1984 Trans Am to replace the old dead cigarette socket. After installing I can still flip the cigarette ash tray door down no problem.Pros: Very easy to install (especially the wiring) either with using the existing cigarette lighter wires or directly to the battery. The charging power is very strong to activate the rapid charge for a Samsung Galaxy Note 9. It's nice to have the option to turn on/off the power to the unit and, to see the battery voltage (handy for cold winter mornings dealing with possible low/dead batteries).Cons: not a big deal breaker for me personally however, beware that this unit does not activate rapid charge for the Google Pixel series phones (apperently they are fussy and wants a full 18 volts for rapid charging)To make long short: great bang for your buck purchase on updating your cars electronics charging system.As the title suggests, these are a bit wider than the factory openings in the 1st gen toyota sequoia. I used basic tools to carve the factory hole wider. Once you get it threaded, they fit in very snuggly. Overall--pretty easy to install; the hardest part (for me) was removing the factory cigarette lighter.The On/Off switch is a great feature, as the sequoia has 3 or 4 outlets that are not switched. So it really gives these outlets new life. But my concern is the how well this switch will hold up. I bought two of these, and the switch in one is already a bit cloogy. Hopefully, it'll last. i dig the voltage meter as well.This is a great product in concept, but the quality control is poor. Be prepared to buy a few before you get one that works reliably.I installed three on my motorcycle before I got one that did not fail. The first unit started having issues after a few weeks. Only one of the USB ports worked, while the other port provided no power at all.The second unit lasted about two months before it started to fail. It intermittently turned itself off. I could turn it back on, but it would only stay on for a few seconds to a few minutes before shutting off again.I've had the third one installed for a few months now. So far, so good. Both USB ports provide power and it doesn't turn itself off. I hope it continues to work.I acknowledge that motorcycles can be a tough environment for electronics due to the vibrations, so I cut the company a little slack. But still, a well-built product shouldn't fail so quickly even on a motorcycle.No es de metal al 100%
