[2 Pack] 12V USB Outlet, Quick Charge 3.0 Dual USB Power Outlet with Touch Switch, Waterproof 12V/24V Fast Charge USB Charger Socket DIY Kit for Car Boat Marine Bus Truck Golf Cart RV Motorcycle, etc.

So far, so good. I installed both chargers, to replace OEM chargers in my camper van. The OEM chargers were 1.0 amp versions, which were not sufficient to reliably charge my iPad. They were also wearing out, so that connection wasn’t reliable. These were easy to install, making sure that polarity was proper, because the slip-on connections were the same as the OEM chargers. I then tested them to make sure that they were working, and so far as I can tell, they are.

Works perfectly

Great item and price.

These are great, but note that if your battery goes below their voltage cut-off you will need a way to plug and replug them. They just cut off until they are reconnected to a charged battery.

these seem pretty well made and pretty high quality compared to most 12v car stuff like this.I used mine to charge a Macbook and Android from a battery. I specifically got one that was fairly high wattage. I haven't tried to max it out and test, but was able to get it to put out at least 40W without any hassle.

This is a good charger. Well made, and good components. First off (super nice feature to save your battery) It defaults to off!!! That's AWESOME! I have installed 3 of these and it's very nice that after power off they stay off till you power them on again! As it should be. It is definitely the higher grade of products in the sea of poor quality on amazon. The threads are good, and it will install well. The switch is awesome - I like that I can turn each individual one on and off and lessen parasitic load on the battery when not in use even if it is a small draw. The only gripe is that they're not really up to the advertised 65 watts of power. Like my laptop won't charge but it will maintain. So good to have but really wished it had the 65 watts to charge the laptop. This will fast charge a phone, but not nearly as fast as an AC powered adapter (for example I compare it to my Anker AC 65w charger). As for the laptop, it will work well if the laptop battery isn't severely drained and in need of a full recharge. All around its good - I really just wish it was up to the true wattage. Heck, I would pay even more than this if it was! Frankly though I would probably order more if the need arrived because I haven't found better.

So, I bought these to use one in my radio go box. I have had problems with one of them, the touch switch works only when it wants. Not a huge problem I just don’t turn it off, as I don’t need to. It is wired to the switch of the power supply so when I turn off the box it shuts off. The other one the switch works just fine.I have not been able to get any of my fast charge devices to kick into fast charge with it. All my devices charge at 1.5 amps which is normal charging current. The parasitic draw of the device is extremely low even with the led light on, not even a ma 21 ma to be exact with the led off it draws 12 ma. This is extremely good. As with all electronics they have a drain even when not in use the trick is to find the ones with the least draw. I was pleasantly surprised to see the draw so low on this device.The power efficiency is right around 62% (see photos above for current draws)Input watts = 0.997 × 12 = 11.964Outputs watts = 1.48 × 5 = 7.4power conversion efficiency formula output watts / input watts x 1007.4 ÷ 11.9 × 100 = 62.18This is right in the ball park of most consumer electronics maybe a little below par as the range is 63% to 80%. However, when we are talking about such small currents and considering the that most of these will be installed in a vehicle the conversion efficiency is just fine for this applicationI would buy these again for projects in the future for the price. They are well built and sturdy.I will update this review after I have used this device in the field for a few months.

Having used this device now for 6 month and I mean used, It’s still going strong . IPad Pro charges in no time at all. The power button issue, well at the time it was an issue but muscle memory/repetition is a wonderful thing. My finger goes right to the power button every time without having to think on it. I’m buying again when I need more and I will.Would be 5 stars but… You must turn it on every time you start up your vehicle. And that button is tiny, it’s a good thing they put a usb-c in because I don’t believe my finger would fit otherwise. As far as power, it’s good enough to charge my iPad Pro and iPhone simultaneously with no issues. I thought the price was fair for two devices with a c port. I can’t speak for all because I’m mechanically inclined and I’ve seen some people who should not pick up a screwdriver. If your buying this there’s a good chance you know what you’re getting and what needs to happen.
